Patients With Higher Treatment Outcome Expectations Are More Satisfied With the Results of Nonoperative Treatment for Thumb Base Osteoarthritis: A Cohort Study

ObjectiveTo investigate how satisfaction with treatment outcome is associated with patient mindset and Michigan Hand Outcome Questionnaire (MHQ) scores at baseline and 3 months in patients receiving nonoperative treatment for first carpometacarpal joint (CMC-1) osteoarthritis (OA).DesignCohort studySettingA total of 20 outpatient locations of a clinic for hand surgery and hand therapy in the Netherlands.ParticipantsPatients (N=308) receiving nonoperative treatment for CMC-1 OA, including exercise therapy, an orthosis, or both, between September 2017 and February 2019.InterventionsNonoperative treatment (ie, exercise therapy, an orthosis, or both)Main Outcome MeasuresSatisfaction with treatment outcomes was measured after 3 months of treatment. We measured total MHQ score at baseline and at 3 months. As baseline mindset factors, patients completed questionnaires on treatment outcome expectations, illness perceptions, pain catastrophizing, and psychological distress. We used multivariable logistic regression analysis and mediation analysis to identify factors associated with satisfaction with treatment outcomes.ResultsMore positive pretreatment outcome expectations were associated with a higher probability of being satisfied with treatment outcomes at 3 months (odds ratio, 1.15; 95% confidence interval, 1.07-1.25). Only a relatively small part (33%) of this association was because of a higher total MHQ score at 3 months. None of the other mindset and hand function variables at baseline were associated with satisfaction with treatment outcomes.ConclusionsThis study demonstrates that patients with higher pretreatment outcome expectations are more likely to be satisfied with treatment outcomes after 3 months of nonoperative treatment for CMC-1 OA. This association could only partially be explained by a better functional outcome at 3 months for patients who were satisfied. Health care providers treating patients nonoperatively for CMC-1 OA should be aware of the importance of expectations and may take this into account in pretreatment counseling.     

Comparative Effectiveness of Orthoses for Thumb Osteoarthritis: A Systematic Review and Network Meta-analysis

ObjectiveTo evaluate the best option among orthoses for carpometacarpal (CMC) osteoarthritis (OA) of the thumb, using a network meta-analysis.Data SourcesMedline, Embase, Cochrane, and ClinicalTrials.gov registry databases were used. PubMed, Embase, Cochrane Controlled Trials Register, Cochrane, and other databases were used without language restrictions.Study SelectionWe searched randomized controlled trials (RCTs) on adults with OA of the thumb by studying any orthosis from the beginning to March 10, 2020.Data ExtractionData were extracted and checked for accuracy and completeness by pairs of reviewers. Outcomes were pain and function. Comparative treatment effects were analyzed by random-effects model for direct pairwise comparisons and Bayesian network meta-analyses to integrate direct and indirect evidence.Data SynthesisEleven RCTs involving 619 patients were included. We evaluated 5 groups, for 4 different orthoses: short thermoplastic CMC splint (rigid CMC) (n=5), long thermoplastic carpometacarpal-metacarpophalangeal splint (rigid CMC-MCP) (n=7), short neoprene CMC splint (soft CMC) (n=1), long neoprene CMC-MCP splint (soft CMC-MCP) (n=5), and one as a control group (n=5). Our results show that all splints were superior to placebo to reduce pain intensity and the top-ranked intervention was the rigid CMC-MCP (surface under the cumulative ranking curve analysis [SUCRA], score: 65.4). In function evaluation, we report a 71.6 SUCRA for rigid CMC.ConclusionsAlthough the current evidence is unclear on the use of the splint in OA of the thumb, it is not known which orthosis is more effective and whether the orthosis is more effective than other interventions. The network meta-analysis shows that a long thermoplastic splint it is the best choice for pain relief and the short thermoplastic CMC splint is the best treatment to increase function. These results may suggest initial treatment with a long rigid orthosis and then a short rigid orthosis.     

Unilateral Strength Training of the Less Affected Hand Improves Cortical Excitability and Clinical Outcomes in Patients With Subacute Stroke: A Randomized Controlled Trial

ObjectivesTo investigate whether unilateral strength training helps improve cortical excitability and clinical outcomes after stroke.DesignRandomized controlled trial.SettingRehabilitation sciences research center.ParticipantsPatients with subacute stroke (N=26) were randomly assigned to a control group (n=13) or the experimental group (n=13).InterventionsParticipants in both groups received conventional physiotherapy. The experimental group also received unilateral strength training of the less affected wrist extensors. Interventions were applied for 4 weeks (12 sessions, 3 d/wk).Main Outcome MeasuresCortical excitability in both the ipsilesional hemisphere (ipsiH) and contralesional hemisphere (contraH) was assessed by measuring resting motor threshold (RMT), active motor threshold (AMT), motor evoked potential (MEP), and cortical silent period (CSP) at baseline and after the 4-week intervention period. Clinical outcomes were obtained by evaluating wrist extension strength in both the more affected and less affected hands, upper extremity motor function, activities of daily living (ADL), and spasticity.ResultsThe experimental group showed greater MEP amplitude (P=.001) in the ipsiH and shorter CSP duration in both the ipsiH (P=.042) and contraH (P=.038) compared with the control group. However, the reductions in RMT and AMT in both hemispheres were not significantly different between groups. Improvements in wrist extension strength in the more affected (P=.029) and less affected (P=.001) hand, upper extremity motor function (P=.04), and spasticity (P=.014) were greater in the experimental group. No significant difference in ADLs was detected between groups.ConclusionsA combination of unilateral strength training and conventional physiotherapy appears to be a beneficial therapeutic modality for improving cortical excitability and some clinical outcomes in patients with stroke.     

Effectiveness of Botulinum Toxin Treatment for Upper Limb Spasticity Poststroke Over Different ICF Domains: A Systematic Review and Meta-Analysis

ObjectiveTo provide a comprehensive overview of reported effects and scientific robustness of botulinum toxin (BoNT) treatment regarding the main clinical goals related to poststroke upper limb spasticity, using the International Classification of Functioning, Disability and Health.Data SourcesEmbase, PubMed, Wiley/Cochrane Library, and Ebsco/CINAHL were searched from inception up to May 16, 2018.Study SelectionWe included randomized controlled trials comparing upper limb BoNT injections with a control intervention in patients with a history of stroke. A total of 1212 unique records were screened by 2 independent reviewers. Forty trials were identified, including 2718 patients with history of stroke.Data ExtractionOutcome data were pooled according to assessment timing (ie, 4-8wk and 12wk after injection), and categorized into 6 main clinical goals (ie, spasticity-related pain, involuntary movements, passive joint motion, care ability, arm and hand use, and standing and walking performance). Sensitivity analyses were performed for the influence of study and intervention characteristics, involvement of pharmaceutical industry, and publication bias.Data SynthesisRobust evidence is shown for the effectiveness of BoNT in reducing resistance to passive movement, as measured with the (Modified) Ashworth Score, and improving self-care ability for the affected hand and arm after intervention (P<.005) and at follow-up (P<.005). In addition, robust evidence is shown for the absence of effect on arm-hand capacity at follow-up. BoNT was found to significantly reduce involuntary movements, spasticity-related pain, and caregiver burden, and improve passive range of motion, while no evidence was found for arm and hand use after intervention.ConclusionsIn view of the robustness of current evidence, no further trials are needed to investigate BoNT for its favorable effects on resistance to passive movement of the spastic wrist and fingers, and on self-care. No trials are needed to further confirm the lack of effects of BoNT on arm-hand capacity, whereas additional trials are needed to establish the suggested favorable effects of BoNT on other body functions, which may result in clinically meaningful outcomes at activity and participation levels.     

The effects of an 8-week knitting program on osteoarthritis symptoms in elderly women: A pilot randomized controlled trial

BackgroundExercise therapy is effective in reducing symptoms and disability associated with hand osteoarthritis (HOA) but often has low adherence. An intervention consisting in a meaningful occupation, such as knitting, may improve adherence to treatment. This pilot randomized controlled trial (RCT) studied the adherence and clinical effectiveness of a knitting program in older females suffering from HOA to evaluate the acceptability of this intervention and assess the feasibility of a larger-scale RCT.MethodsSingle-blind, two-arm pilot RCT with a parallel group design with 37 participants (18 control, 19 intervention). Control participants were given an educational pamphlet and assigned to a waiting list. The knitting program (8-week duration) had two components: bi-weekly 20-min group knitting sessions and daily 20-min home knitting session on the 5 remaining weekdays. Measures included knitting adherence (implementation outcomes) as well as stiffness, pain, functional status, hand physical activity level, patient's global impression of change, health-related quality of life, self-efficacy, and grip strength (clinical outcomes measured throughout the 8-week program and 4 weeks after the intervention).ResultsOur protocol is feasible and the intervention was acceptable and enjoyable for participants, who showed high adherence. No difference was observed between the two groups for any of the clinical outcome measures (all p > .05).ConclusionKnitting is a safe and accessible activity for older women with HOA. However, our 8-week knitting program did not result in improvements in any of our outcome measures. Knitting for a longer period and/or with higher frequency may yield better outcomes.     

Effects of Virtual Reality and Task-Oriented Training on Hand Function and Activity Performance in Pediatric Hand Burns: A Randomized Controlled Trial

ObjectiveTo assess the efficacy of a motion-sensing, hands-free gaming device and task-oriented training (TOT) programs on improving hand function, activity performance, and satisfaction in pediatric hand burns.DesignA randomized controlled trial.SettingOutpatient rehabilitation center.ParticipantsFifty children with deep partial-thickness or full-thickness hand burns. (N=50; mean age, 10.70±1.64y; range, 7-14y)InterventionsChildren were randomized into 1 of the following 3 groups: the motion-sensing, hands-free gaming device group that used interactive video games plus traditional rehabilitation (TR); the TOT group that used real materials plus TR; and the control group that only received TR, all groups received the interventions 3 days per week for 8 weeks.Main Outcome MeasuresWe assessed the children at the baseline and after 8 weeks of intervention. The primary outcome measures were the Jebsen-Taylor Hand Function Test, Duruoz Hand Index (DHI), and Canadian Occupational Performance Measure (COPM). The secondary outcome measures were range of motion (ROM) of the digits, grip strength, and pinch strengths (tip, palmer, and lateral pinch).ResultsThere was a significant increase in all measurements of the motion-sensing, hands-free gaming device and TOT groups compared with that of the control group postintervention (P<.05). There was no significant change in Jebsen-Taylor Hand Function Test, COPM performance, ROM, grip strength, and tip and lateral pinch strengths between the motion-sensing, hands-free gaming device group and TOT group (P>.05), whereas there was a significant increase in DHI, COPM satisfaction, and palmer pinch strength (P<.05) in the motion-sensing, hands-free gaming device group compared with the TOT group postintervention.ConclusionsThe motion-sensing, hands-free gaming device and TOT programs resulted in significant improvement in hand function, activity performance and satisfaction, ROM of the digits, grip strength, and pinch strengths in pediatric hand burns compared with the traditional hand rehabilitation.     

Effects of Tai Chi on Lower Limb Proprioception in Adults Aged Over 55: A Systematic Review and Meta-Analysis

ObjectiveTo summarize and critically evaluate the effects of Tai Chi on lower limb proprioception in adults older than 55.Data SourcesSeven databases (Scopus, PubMed, Web of Science, SPORTDiscus, Cochrane Library, Wanfang, CNKI) were searched from inception until April 14, 2018.Study SelectionEleven randomized controlled trials were included for meta-analysis.Data ExtractionTwo independent reviewers screened potentially relevant studies based on the inclusion criteria, extracted data, and assessed methodological quality of the eligible studies using the Physiotherapy Evidence Database (PEDro).Data SynthesisThe pooled effect size (standardized mean difference [SMD]) was calculated while the random-effects model was selected. Physiotherapy Evidence Database scores ranged from 5 to 8 points (mean=6.7). The study results showed that Tai Chi had significantly positive effects on lower limb joint proprioception. Effect sizes were moderate to large, including ankle plantar flexion (SMD=−0.55; 95% confidence interval [95% CI], −0.9 to −0.2; P=.002; I²=0%; n=162), dorsiflexion (SMD=−0.75; 95% CI, −1.11 to −0.39; P<.001; I²=0%; n=162), nondominant or left knee flexion (SMD=−0.71; 95% CI, −1.10 to −0.41; P<.001; I²=25.1%; n=266), dominant or right knee flexion (SMD=−0.82; 95% CI, −1.06 to −0.58; P<.001; I²=33.8%; n=464).ConclusionsThere is moderate to strong evidence that suggests that Tai Chi is an effective intervention to maintain and improve lower limb proprioception in adults older than 55. More robust multicenter studies including oldest-old participants, with longer follow-ups and validated outcome measures, are needed before a definitive conclusion is drawn.     

The effectiveness of biomechanical taping and Kinesiotaping on shoulder pain,active range of motion and function of participants with Trapezius Myalgia: A randomized controlled trial

BackgroundTrapezius Myalgia (TM) is characterized by shoulder pain and dysfunction. Kinesio Taping is commonly used in symptom management of TM. Biomechanical Taping (BMT), a novel intervention, may provide equally effective management.ObjectivesThis paper reports on the effectiveness of Biomechanical Taping compared with Kinesio Taping in improving shoulder pain, active range of motion (AROM), and function.MethodsTwo groups of participants with TM were recruited through simple random sampling of participants from nine call centers and purposively-sampled participants from one fast-food chain and one community based rehabilitation center in Manila, Philippines. Participants were randomly allocated to either Kinesio Taping or biomechanical taping group in a double-blind clinical trial. Irrespective of the type of taping, participants performed gentle passive stretching of upper trapezius for six times each held for 30 s on Days 1, 3, and 5. On Days 2 and 4, participants performed gentle passive stretch of upper trapezius three times a day. Pre- and post-intervention measures were taken of Visual Analogue Scale for pain intensity, AROM for shoulder movement, and Disability of Arm, Shoulder, and Hand for function.ResultsOf 68 participants, 62 had shoulder symptoms secondary to TM. Similar significant within group improvements were found for Visual Analogue Scale scores, and Disability of Arm, Shoulder and Hand for biomechanical taping and Kinesio Taping interventions when comparing between group results (p < 0.05).ConclusionBiomechanical Taping appears to be as effective as Kinesio Taping in the short term in decreasing pain and improving function of individuals with TM. Both taping techniques did not restrict shoulder AROM of included participants.Mesh TermsAthletic Tape, Myalgia, Pain Measurements, Shoulder PainNon-Mesh TermsBiomechanical Taping Technique     

Gait- and Posture-Related Factors Associated With Changes in Hip Pain and Physical Function in Patients With Secondary Hip Osteoarthritis: A Prospective Cohort Study

ObjectiveTo identify gait- and posture-related factors associated with changes in hip pain and physical function in patients with hip osteoarthritis (OA).DesignProspective cohort study.SettingClinical biomechanics laboratory of a university.ParticipantsConsecutive sampling of female patients with mild-to-moderate secondary hip OA (N=30).Main Outcome MeasuresHip pain (visual analog scale) and physical function (physical component summary of the Medical Outcomes Study 36-Item Short-Form Health Survey) were measured at baseline and 12 months later. With changes in hip pain and physical function as dependent variables, linear regression analyses were performed with gait- and posture-related factors as independent variables with and without adjustment for age, joint space width, and hip pain or physical function at baseline. Posture-related factors included angles of thoracic kyphosis, lumbar lordosis, sacral inclination, spinal inclination, and spinal mobility. Gait-related factors were walking speed, steps per day, joint angles, external hip joint moment impulses, and daily cumulative hip moments.ResultsMultiple linear regression analyses showed that limited hip extension (adjusted standardized B coefficient [95% confidence interval]: −0.52 [−0.88 to −0.17]) and limited external rotation angles (−0.51 [−0.85 to −0.18]) during walking were associated with the worsening of hip pain. An increased thoracic kyphosis (−0.54 [−0.99 to −0.09]), less sacral anterior tilt (0.40 [0.01-0.79]), reduced thoracic spine mobility (0.59 [0.23-0.94]), less steps per day (0.53 [0.13-0.92]), and a slower walking speed (0.45 [0.04-0.86]) were associated with deterioration in physical function.ConclusionsGait- and posture-related factors should be considered when assessing risk and designing preventive interventions for the clinical progression of secondary hip OA.     

Effect of a Novel Perturbation-Based Pinch Task Training on Sensorimotor Performance of Upper Extremity for Patients With Chronic Stroke: A Pilot Randomized Controlled Trial

ObjectiveTo investigate the effects of perturbation-based pinch task training on the sensorimotor performance of the upper extremities of patients with chronic stroke via a novel vibrotactile therapy system.DesignA single-blinded randomized controlled trial.SettingA university hospital.ParticipantsPatients with chronic stroke (N=19) randomly assigned into either an experimental group or a control group completed the study.InterventionsIn addition to 10 minutes of traditional sensorimotor facilitation, each participant in the experimental group received 20 minutes of perturbation-based pinch task training in each treatment session, and the controls received 20 minutes of task-specific motor training twice a week for 6 weeks.Main Outcome MeasuresThe scores for the primary outcome, Semmes-Weinstein monofilament (SWM), and those for the secondary outcomes, Fugl-Meyer Assessment (FMA), amount of use, quality of movement (QOM) on the Motor Activity Log (MAL) scale, and box and block test (BBT), were recorded. All outcome measures were recorded at pretreatment, post treatment, and 12-week follow-up.ResultsThere were statistically significant between-group differences in the training-induced improvements revealed in the SWM results (P=.04) immediately after training and in the BBT results (P=.05) at the 12-week follow-up. The changes in muscle tone and in the QOM, SWM, and BBT scores indicated statistically significant improvements after 12 sessions of treatment for the experimental group. For the control group, a significant statistical improvement was found in the wrist (P<.001) and coordination (P=.01) component of the FMA score.ConclusionsThis study indicated that the perturbation-based pinch task training has beneficial effects on sensory restoration of the affected thumb in patients with chronic stroke.     

Effect of Psychomotricity in Combination With 3 Months of Active Shoulder Exercises in Individuals With Chronic Shoulder Pain: Primary Results From an Investigator-Blinded,Randomized, Controlled Trial

ObjectiveTo evaluate whether psychomotor therapy (PMT) in combination with usual care active exercise (AE) rehabilitation for the shoulder is superior to merely AE.DesignThe trial was a single-center, stratified (by corticosteroid injection [yes or no]), randomized, and controlled superiority trial.SettingShoulder unit of the orthopedic department at Hospital Lillebaelt, Vejle Hospital.ParticipantsEligible participants (N=87) were adults aged 18-75 years with shoulder complaints lasting for at least 3 months, in addition to a score equal to or below 3 on the Multidimensional Assessment of Interoceptive Awareness score. Furthermore, patients had at least a visual analog scale pain score of 2 at rest, 3 at night, and 5 in activity (range: 0-10).InterventionsPatients were randomized to 12 weeks of AE (control group) or in combination with 5 PMT sessions (intervention group).Main Outcome MeasureThe primary outcome was the patient-reported outcome score Disability of the Arm, Shoulder and Hand questionnaire. The primary endpoint was 12 weeks after baseline.ResultsThere was no between-group difference in function between the intervention group and control group.ConclusionsOur results showed no additional benefit on patient-reported function and pain from PMT over usual care in patients with long-lasting shoulder pain and low body awareness. This finding suggests that PMT adds no additional benefit to patients’ recovery in relation to pain and active function in comparison to standard care.     

Comparative Relevance of Physical Fitness and Adiposity on Life Expectancy: A UK Biobank Observational Study

ObjectiveTo investigate the extent to which 2 measures of physical fitness—walking pace and handgrip strength—are associated with life expectancy across different levels of adiposity, as the relative importance of physical fitness and adiposity on health outcomes is still debated.Patients and MethodsUsual walking pace (self-defined as slow, steady/average, brisk), dynamometer-assessed handgrip strength, body mass index (BMI), waist circumference, and body-fat percentage determined at baseline in the UK Biobank prospective cohort study (March 13, 2006, to January 31, 2016). Life expectancy was estimated at 45 years of age.ResultsThe median age and BMI of the 474,919 participants included in this analysis were 58.2 years and 26.7 kg/m², respectively; over a median follow-up of 6.97 years, 12,823 deaths occurred. Participants reporting brisk walking pace had longer life expectancies across all levels of BMIs, ranging from 86.7 to 87.8 years in women and 85.2 to 86.8 years in men. Conversely, subjects reporting slow walking pace had shorter life expectancies, being the lowest observed in slow walkers with a BMI less than 20 kg/m² (women: 72.4 years; men: 64.8 years). Smaller, less consistent differences in life expectancy were observed between participants with high and low handgrip strength, particularly in women. The same pattern of results was observed for waist circumference or body-fat percentage.ConclusionBrisk walkers were found to have longer life expectancies, which was constant across different levels and indices of adiposity. These findings could help clarify the relative importance of physical fitness and adiposity on mortality.     

The Effectiveness of Instrument-Assisted Soft Tissue Mobilization in Athletes,Participants Without Extremity or Spinal Conditions,and Individuals with Upper Extremity,Lower Extremity,and Spinal Conditions: A Systematic Review

ObjectiveTo assess the effectiveness of instrument-assisted soft tissue mobilization (IASTM) to other treatments or placebo in athletes or participants without extremity or spinal conditions and individuals with upper extremity, lower extremity, and spinal conditions.Data SourcesThe MEDLINE, EMBASE, CINAHL, and PEDro electronic databases were searched from January 1998 to March 2018.Study SelectionRandomized controlled trials of participants without extremity or spinal conditions or athletes and people with upper extremity, lower extremity, or spinal conditions, who revived IASTM vs other active treatment, placebo, or control (no treatment), to improve outcome (function, pain, range of motion).Data ExtractionTwo independent review authors extracted data, assessed the trials for risk of bias using the Cochrane Risk of Bias tool in included studies, and performed the rating of quality of individual trials per outcome across trials was also performed using the Grading of Recommendations, Assessment, Development, and Evaluations guidelines.Data SynthesisNine trials with 43 reported outcomes (function, pain, range of motion, grip strength), compared the addition of IASTM over other treatments vs other treatments. Six trials with 36 outcomes reported no clinically important differences in outcomes between the 2 groups. Two trials with 2 outcomes displayed clinically important differences favoring the other treatment (without IASTM) group. Six trials with 15 reported outcomes (pressure sensitivity, pain, range of motion, muscle performance), compared IASTM vs control (no treatment). Three trials with 5 outcomes reported no clinically important differences in outcomes between the 2 groups. Furthermore, in 1 trial with 5 outcomes, IASTM demonstrated small effects (standard mean difference range 0.03-0.24) in terms of improvement muscle performance in physically active individuals when compared to a no treatment group.ConclusionThe current evidence does not support the use of IASTM to improve pain, function, or range of motion in individuals without extremity or spinal conditions or those with varied pathologies.     

Change in Function Over Inpatient Rehabilitation After Hypoxic Ischemic Brain Injury: A Population-Wide Cohort Study

ObjectiveTo estimate change in motor, cognitive, and overall functional performance during inpatient rehabilitation (IR) and to identify potential determinants of these outcomes among patients with hypoxic-ischemic brain injury (HIBI).DesignPopulation-based retrospective cohort study using Ontario’s health administrative data.SettingInpatient rehabilitation.ParticipantsSurvivors of HIBI 20 years and older discharged from acute care between fiscal years 2002-2003 and 2010-2011 and admitted to IR within 1 year of acute care discharge (N=159).InterventionsNot applicable.Main Outcome MeasureFunctional status as measured by FIM, total, and scores on motor and cognitive subscales.ResultsA higher proportion (77%) of HIBI patients in the study were male and 28% were older than 65 years. We observed material improvements in FIM total, motor, and cognitive scores from across the IR episode. Potential determinants of total FIM gain were living in rural location (β, 10.4; 95% CI, 0.21-21), having shorter preceding acute care length of stay (15-30 vs >60 days β, 10.4; 95% CI, 1.4-19.5), and failing to proceed directly to IR following acute care discharge (β, 8.7; 95% CI, 1.8-15.5). Motor FIM gain had similar identified potential determinants. Identified potential determinants of cognitive FIM gain were shorter (ie, 31-60 vs >60 days) preceding acute care, longer IR and length of stay, and proceeding directly to IR. There were no sex differences in functional gain.ConclusionsInpatient rehabilitation is beneficial to HIBI survivors. Timely access to these services may be crucial in achieving optimal outcomes for these patients.     

One-Year Efficacy of Platelet-Rich Plasma for Moderate-to-Severe Carpal Tunnel Syndrome: A Prospective,Randomized, Double-Blind,Controlled Trial

ObjectiveTo assess the therapeutic effect of platelet-rich plasma (PRP) for moderate-to-severe carpal tunnel syndrome (CTS).DesignA prospective, randomized, double-blinded, controlled trial (1-year follow-up).SettingOutpatient of local medical center settings.ParticipantsPatients (N=26) who were diagnosed with bilateral moderate-to-severe CTS (total 52 wrists) were included. For each patient, one wrist was randomized into either the PRP or control group and the contralateral wrist of the same patient was allocated to another group.Twenty-four patients were included in the final data analysis.InterventionsThe wrists in the PRP group received a single ultrasound-guided dose of PRP injection (3.5mL), and the control group received a single ultrasound-guided injection with normal saline (3.5mL).Main Outcome MeasuresThe Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) scores were used as the primary outcome. Secondary outcomes encompassed the cross-sectional area of the median nerve and electrophysiological study. Assessments were conducted prior to injection and 1, 3, 6, and 12 months postinjection.ResultsCompared to the control group, the PRP group exhibited significant improvements in BCTQ severity scores at all time points, BCTQ functional scores at the sixth month, and cross-sectional area at the 12th month postinjection (P<.0125).ConclusionsA single dose of ultrasound-guided perineural PRP injection can provide therapeutic effect for 1 year postinjection.     

Failure to Compensate: Patients With Nerve Injury Use Their Injured Dominant Hand,Even When Their Nondominant Is More Dexterous

ObjectiveTo identify how individuals respond to unilateral upper extremity peripheral nerve injury via compensation (increased use of the nondominant hand). We hypothesized that injury to the dominant hand would have a greater effect on hand use (left vs right choices). We also hypothesized that compensation would not depend on current (postinjury) nondominant hand performance because many patients undergo rehabilitation that is not designed to alter hand use.DesignObservational survey, single-arm.SettingsAcademic research institution and referral center.ParticipantsA total of 48 adults (N=48) with unilateral upper extremity peripheral nerve injury. Another 14 declined participation. Referred sample, including all eligible patients from 16 months at 1 nerve injury clinic and 1 hand therapy clinic.InterventionsNot applicable.Main Outcome MeasuresHand use (% of actions with each hand) via Block Building Task. Dexterity via Jebsen-Taylor Hand Function.ResultsParticipants preferred their dominant hand regardless of whether it was injured: hand usage (dominant/nondominant) did not differ from typical adults, regardless of injured side (P>.07), even though most participants (77%) were more dexterous with their uninjured nondominant hand (mean asymmetry index, ?0.16±0.25). The Block Building Task was sensitive to hand dominance (P=2 × 10^?4) and moderately correlated with Motor Activity Log amount scores (r²=0.33, P<.0001). Compensation was associated only with dominant hand dexterity (P=3.9 × 10^?3), not on nondominant hand dexterity, rehabilitation, or other patient and/or injury factors (P>.1).ConclusionsPatients with peripheral nerve injury with dominant hand injury do not compensate with their unaffected nondominant hand, even if it is more dexterous. For the subset of patients unlikely to recover function with the injured hand, they could benefit from rehabilitation that encourages compensation with the nondominant hand.     

Impact of Pulmonary Hypertension on In-Hospital Outcomes and 30-Day Readmissions Following Percutaneous Coronary Interventions

ObjectiveTo evaluate the impact of pulmonary hypertension (PH) on percutaneous coronary intervention (PCI) outcomes and 30-day all-cause readmissions by analyzing a national database.MethodsWe queried the 2014 National Readmissions Database to identify patients undergoing PCI using International Classification of Diseases, Ninth Revision, Clinical Modification codes. These patients were then subcategorized based on the coded presence or absence of PH and further analyzed to determine the impact of PH on clinical outcomes, health care use, and 30-day readmissions.ResultsAmong 599,490 patients hospitalized for a PCI in 2014, 19,348 (3.2%) had concomitant PH. At baseline, these patients were older with a higher burden of comorbidities. Patients with PH had longer initial hospitalizations and higher 30-day readmission rates and mortality than their non-PH counterparts. This was largely driven by cardiac causes, most commonly heart failure (20.3% vs 9.0%, P<.001) and non–ST-segment elevation myocardial infarction. Recurrent coronary events (17.5% vs 9.5%, P<.05) including ST-segment elevation myocardial infarction predominated in the non-PH group.ConclusionPatients with PH undergoing PCI are a high-risk group in terms of mortality and 30-day readmission rates. Percutaneous coronary intervention in patients with PH is associated with higher rates of recurrent heart failure and non–ST-segment elevation myocardial infarction, rather than recurrent coronary events or ST-segment elevation myocardial infarction. This perhaps indicates a predominance of demand ischemia and heart failure syndromes rather than overt atherothrombosis in the etiology of chest pain in these patients.     

Nebulized colistin as the adjunctive treatment for ventilator-associated pneumonia: A systematic review and meta-analysis

PurposeNebulized colistin (NC) is a potential therapy for ventilator-associated pneumonia (VAP); however, the clinical efficacy and safety of NC remain unclear. This study investigated whether NC is an effective therapy for patients with VAP.Materials and methodsWe performed a search in Web of Science, PubMed, Embase, and the Cochrane Library to retrieve randomized controlled trials (RCTs) and observational studies published at any time until February 6, 2023. The primary outcome was clinical response. Secondary outcomes included microbiological eradication, overall mortality, length of mechanical ventilation (MV), length of intensive care unit stay (ICU-LOS), nephrotoxicity, neurotoxicity, and bronchospasm.ResultsSeven observational studies and three RCTs were included. Despite exhibiting a higher microbiological eradication rate (OR,2.21; 95%CI, 1.25–3.92) and the same nephrotoxicity risk (OR,0.86; 95%CI, 0.60–1.23), NC was not significantly different in clinical response (OR,1.39; 95%CI, 0.87–2.20), overall mortality (OR,0.74; 95%CI, 0.50–1.12), MV length (mean difference (MD),-2.5; 95%CI, −5.20–0.19), and the ICU-LOS (MD,-1.91; 95%CI, −6.66–2.84) than by the intravenous antibiotic. Besides, the risk of bronchospasm raised significantly (OR, 5.19; 95%CI, 1.05–25.52) among NC.ConclusionNC was associated with better microbiological outcomes but did not result in any remarkable changes in the prognosis of patients with VAP.     

Ultrasound-Guided Standard vs Dual-Target Subacromial Corticosteroid Injections for Shoulder Impingement Syndrome: A Randomized Controlled Trial

ObjectiveTo compare dual-target injection with standard ultrasound (US)-guided subacromial injection in patients with subacromial impingement syndrome (SIS) and possible disorders of the biceps long-head tendons.DesignDouble-blind, randomized controlled trial.SettingRehabilitation outpatient clinic.ParticipantsPatients with SIS (N=60).Intervention(1) US-guided standard subacromial bursa; (2) dual-target (subacromial bursa plus proximal biceps long-head tendon) injection, with 40-mg triamcinolone acetonide administered to patients in each group.Main Outcome MeasuresClinical assessments were performed at baseline. The outcomes, including results from a self-administered questionnaire, the Shoulder Pain and Disability Index (SPADI), and a self-pain report, the visual analog scale (VAS) scores for pain at rest, at night, and during overhead activities, were evaluated at baseline and at the first and third months postintervention.ResultsNo significant difference was observed in baseline evaluations between groups (n=30 in each treatment arm) prior to injections. Both groups exhibited significant SPADI and VAS-score improvements after the first month. The dual-target injection group had less rebounding pain at the 3-month follow-up. The standard injection group had more patients reporting worsening pain within 1 day postinjection.ConclusionUS-guided dual-target corticosteroid injection showed similar short-term efficacy to standard subacromial injections, but with an extended duration of symptom relief. Therefore, dual-target corticosteroid injections may be useful for shoulder pain treatment in patients with SIS.     

Optimal Multifield Functional Electrical Stimulation Parameters for the “Turn on the Light” Task and Related Upper Limb Kinematics Repeatability in Poststroke Subjects

ObjectiveTo characterize the optimal functional electrical stimulation (FES) parameters that assist the turn on the light task (TOTL) on poststroke participants and to analyze the related upper limb (UL) kinematics repeatability.DesignCross-sectional study.SettingHuman movement research center.ParticipantsPoststroke individuals (N=11) with history of a single unilateral stroke that resulted in a motor control dysfunction of the contralesional UL.InterventionsFES based on surface multifield technology applied to the contralesional wrist and finger extensors during the TOTL.Main Outcome MeasuresFES outcome metrics (virtual electrodes, stimulation duration, intensity) and kinematic metrics (end-point kinematics [absolute and relative duration, mean and peak velocities, relative instant of peak velocity, index of curvature, number of movement units] and joint kinematics [shoulder, elbow, wrist end position and range of movement]). Outcome measures were assessed 2 times with a 72-hour maximum time interval.ConclusionIt was possible to establish reliable FES parameters that assisted the TOTL on poststroke participants. These stimulation parameters led to high to very high repeatability in terms of UL kinematics for most of the cases.
