Effect of different postures of the scapular girdle and arm on the pressure pain threshold in the infraspinatus muscle

BackgroundMechanosensitivity changes and trigger points in the infraspinatus muscle are associated with several painful conditions of the upper limb. The aim of this study was to assess the effect of different postures of the upper quadrant on the pressure pain threshold (PPT) of the infraspinatus muscle.MethodsThis was an observational, cross-sectional study. Fifty-four subjects with and without shoulder pain (Asymptomatic subjects = 27, mean age 26.9 ± 4.92 years, BMI 23.73 ± 3.87), (symptomatic subjects = 27, mean age 27.6 ± 3.68 years, BMI 24.35 ± 3.86) were evaluated with a pressure algometer on the infraspinatus muscle belly, in four different positions of the upper quadrant: rest position (P1), passive scapular retraction position (P2), cervical contralateral inclination position (P3), and suprascapular nerve provocation position (P4). The assessed side was randomly chosen and all measurements were taken in sitting position.ResultsNo differences were observed between groups. The within-group analysis showed differences for both factors: “Positions” (F = 69.91; p = 0.001) and the interaction “Positions^Group” (F = 3.36; p = 0.02). The pairwise post-hoc analysis showed differences for the retracted position (P2) compared to others P1 (p = 0.001), P3 (p = 0.001), and P4 (p = 0.001), with higher PPT results achieved on the retracted position. Differences between P4 vs. P1 (p = 0.03) were also observed, with higher values for P4.ConclusionPlacing the scapular girdle in a passive scapular retraction position significantly reduces the pressure sensitivity at the infraspinatus muscle. Physiotherapists can take into account these results when assessing and treating patients with upper quadrant pain syndromes.     

Positional release therapy and therapeutic massage reduce muscle trigger and tender points

ObjectiveTo determine if positional release therapy (PRT) or therapeutic massage (TM) was more effective in the treatment of trigger and tender points in the upper trapezius muscle.BackgroundTrigger points in the upper trapezius muscle are common and can be painful. Trigger points are commonly treated using TM however, PRT is a novel treatment that deserves further investigation.MethodsSixty healthy male (24) and female (36) participants, (age = 27.1 ± 8.8 years, wt = 75.2 ± 17.9 kg, ht = 172.8 ± 9.7 cm) presenting with upper trapezius pain and a trigger point were recruited and randomized into either the TM or PRT group. Upper trapezius trigger points were found via palpation. Pain level was evaluated using a visual analog scale (VAS) and pain pressure threshold (PPT) was assessed using a pressure algometer. Muscle thickness was measured by B-mode ultrasound, while muscle stiffness was measured by shear-wave elastography (SWE). Participants were measured at baseline, posttreatment and again 48 h later.ResultsBoth treatments were effective in treatment of pain and muscle stiffness. Although no statistical group differences existed, treatment using PRT showed decreased pain averages and decreased pressure sensitivity at both post treatment, and 48 h later. Neither treatment was able to maintain the reduced muscle stiffness at the 48-h measure in males.ConclusionBoth treatments showed a significant ability to reduce pain and acutely decrease muscle stiffness. Although not statistically different, clinically PRT is more effective at decreasing pain, and decreasing pressure sensitivity. Neither treatment method produced a long lasting effect on muscle stiffness in males.     

Association between trigger points in hamstring,posterior leg,foot muscles and plantar fasciopathy: A cross- sectional study

BackroundPlantar Fasciopathy (PF) is soreness or irritability experienced underneath infero-medial aspect of the heel. It is a multifactorial disorder where myofascial involvement also seems to be associated with it, in which, muscles of posterior thigh, leg and foot muscles are affected. Trigger points in these muscles may interfere with biomechanics and normal functioning of the lower limb.ObjectiveTo find an association between trigger points of the posterior thigh, leg and foot muscles and plantar fasciopathy.Study designA cross sectional study.Methods100 patients with plantar fasciopathy who fulfilled inclusion criteria were included in this study. They were examined for trigger points by manual palpation in posterior thigh, leg and foot muscles. Totally 15 muscles were examined on both affected and unaffected side.ResultsResults showed that myofascial trigger points were more prevalent in medial gastrocnemius (98%, Chi-square: 110.07, p < 0.05, Phi-0.74), quadratus plantae (83%, Chi-square:126.96, p < 0.05, Phi- 0.79), soleus (69%, Chi-square: 28.88, p < 0.05, Phi-0.38), tibialis posterior (46%, Chi-square 41.98 p<0.05%, Phi-0.50), abductor hallucis (42%, Chi-square: 43.61 p<0.05% Phi-0.46), flexor halluces longus (41%, Chisquare: 39.25, p < 0.05, Phi-0.44) than other muscles on the affected side. Whereas, on the unaffected side, trigger points were more prevalent among peroneus longus (50%, Chi-square: 26.14, p < 0.05, Phi-0.36) followed by medial gastrocnemius (26%, Chisquare: 110.07, p < 0.05, Phi-0.74).ConclusionPlantar fasciopathy is strongly associated with trigger points of medial gastrocnemius, quadratus plantae followed by soleus, tibialis posterior, abductor hallucis and flexor hallucis longus.     

Mapping nursing interventions using the Therapeutic Intervention Scoring System in bloodless liver transplantations

BackgroundThe Simplified Therapeutic Intervention Scoring System adapted to liver transplantation by King's College Hospital rank 138 activities to determine the nursing workload, diagnostic, monitoring and therapeutic needs.ObjectivesTo evaluate nursing activities of “King’s-TISS” score grouped in organ systems and nurse patient ratio in the perioperative 48 hours of blood product free liver transplantations (LT).MethodsThe “King’s-TISS” score’s were analysed by nursing procedures and grouped, scored according to organ systems. The nursing workloads were studied during LT (T1), on arrival on the ICU (T2) and 12–24-48 hours after LT (T3-T4-T5).ResultsThe total of “King’s-TISS” score points were decreased by ≥20% daily (p = 0.001). The mean score of 104 ± 3.5 points (CI:104–105) during LT decreased to 84.7 ± 12 points (CI:83–86) in 48 hours (T5). The “metabolic” and “haemostasis” points increased (p = ).01), the “immunology” points unchanged (T2-T5) postoperatively. A slight decrease was observed in case of “basic nursing care”, “monitoring”, “neurologic support”, “renal support” and “cardiovascular support” points (T2-T5, p < .01). The “invasive intervention” and “ventilatory support” points strongly decreased (T2-T5, p < .001). One “King’s-TISS” point was found to equal 7.4 minutes with a nurse patient ratio of 2:1 intraoperatively and 1:1 postoperatively.ConclusionAbsence of blood product administration in LT decreases the total and organ specific workload, except the metabolic, haemostasis, immunology and basic support requirement. It was not within the scope of the King’s-TISS score to analyse the application of viscoelastic haemostasis test and coagulation factor concentrate administration.     

Pressure pain hypersensitivity and referred pain from muscle trigger points in elite male wheelchair basketball players

BackgroundShoulder injuries are common in individuals who use wheelchairs.ObjectivesThis study investigated the presence of mechanical pain hypersensitivity and trigger points in the neck-shoulder muscles in elite wheelchair basketball players with/without shoulder pain and asymptomatic able-bodied elite basketball players.MethodsEighteen male wheelchair basketball players with shoulder pain, 22 players without shoulder pain, and 20 able-bodied elite male basketball players were recruited. Pressure pain thresholds were assessed over C5-C6 zygapophyseal joint, deltoid muscle, and second metacarpal. Trigger points in the upper trapezius, supraspinatus, teres minor, infraspinatus, teres major, latissimus dorsi, subscapularis, pectoralis minor, pectoralis major and deltoid muscles were also examined.ResultsWheelchair basketball players with shoulder pain showed lower pressure pain thresholds over the C5-C6 joint and second metacarpal than elite wheelchair basketball players without pain (between-groups differences: 1.1, 95%CI 0.4, 1.8 and 1.8, 95%CI 0.8, 2.8, respectively) and able-bodied basketball players without pain (between-groups differences: 0.8, 95%CI 0.4, 1.2; 1.6, 95%CI 0.8, 2.4, respectively). The mean number of myofascial trigger points for wheelchair basketball players with unilateral shoulder pain was 4.8 ± 2.7 (2 ± 1 active, 2.9 ± 2.2 latent). Wheelchair basketball players and able-bodied basketball players without shoulder pain exhibited a similar number of latent trigger points (2.4 ± 2.0 and 2.4 ± 1.8, respectively). Wheelchair basketball players with shoulder pain exhibited higher number of active myofascial trigger points than those without pain (either with or without wheelchair), but all groups had a similar number of latent trigger points (P < 0.05).ConclusionsThe reported mechanical pain hypersensitivity suggests that active trigger points may play a role in the development of shoulder pain in elite male wheelchair basketball players.     

Pilates method on pulmonary function and range of motion after coronary artery bypass grafting: A clinical trial

IntroductionCoronary artery bypass grafting (CABG) can compromise pulmonary function and range of motion (ROM) of the shoulder and knee joints due to median sternotomy and saphenectomy, the Pilates method being a strategy for reducing loss.ObjectiveTo evaluate the effect of applying the Pilates method on pulmonary function and ROM in patients undergoing CABG.Methodology: This is a clinical trial. Patients were evaluated preoperatively at discharge from the hospital for shoulder flexion and abduction and knee flexion-extension. In addition, vital capacity(VC), maximum inspiratory pressure(MIP), expiratory pressure(MEP) and peak expiratory flow(PEF) were evaluated. Upon discharge from the Intensive Care Unit (ICU), they were divided into a control group(CG) that received conventional assistance and Pilates(PG) was increased with Pilates method techniques.Results40 patients were analyzed, 25 were men(61%), with a mean age of 66 ± 7 years. At the end, the left shoulder abduction in the CG was 105±9vs115 ± 8 in the PG(p = 0.03), the right shoulder abduction in the CG 104 ± 11vs116 ± 10 in the PG(p < 0.001) and right knee flexion in the CG 78 ± 13vs92 ± 9 in the PG(0.002). In relation to MIP, the CG had a loss of 32 ± 8 while the PG 18 ± 10cmH2O(p < 0.001), the worsening MEP was 31 ± 9(CG)vs29 ± 11cmH2O(PG)(p = 0.53), the VC in the CG reduced 8±9vs6±8 in the PG(p = 0.23) and the PEF reduced 107 ± 5 in the GCvs83 ± 88 in the PG(p = 0.09).ConclusionIt is concluded that the Pilates method decreased the loss of ROM and maximum inspiratory pressure in patients undergoing coronary artery bypass grafting.     

The effects of a sensory stimulation intervention on psychosocial and clinical outcomes of critically ill patients and their families: A randomised controlled trial

ObjectivesTo explore the effectiveness of a sensory stimulation intervention on intensive care unit patients' psychosocial, clinical, and family outcomes.DesignA prospective, assessor-blind, parallel-group randomised controlled trial.SettingA surgical intensive care unit of one tertiary hospital in Guangzhou, mainland China.InterventionParticipants in the intervention group received a daily 30-minute auditory and visual stimulation session starting from recruitment and for a maximum of seven days while in the intensive care unit.Measurement and main resultsOne hundred fifty-two patients and family caregiver dyads were recruited. Patients in the intervention group showed lower total scores of post-traumatic stress disorder (21.92 ± 6.34 vs 27.62 ± 10.35, p = 0.001), depressive symptoms (3.76 ± 3.99 vs 6.78 ± 4.75, p = 0.001) and delusional memories (0.47 ± 0.92 vs 0.82 ± 1.23, p = 0.001) collected immediately post-intervention than those in the control group, while not on depressive symptoms at one-month post-intervention (3.32 ± 4.03 vs 3.28 ± 3.77, p = 0.800). Sensory stimulation did not significantly impact patients' unit length of stay and 30-day mortality (all p > 0.05). For family outcomes, family caregivers in the intervention group had greater satisfaction with care (127.12 ± 14.14 vs 114.38 ± 21.97, p = 0.001) and a lower level of anxiety (28.49 ± 6.48 vs 34.64 ± 7.68, p = 0.001) than family caregivers in the control group.ConclusionsSensory stimulation may benefit patients' and family caregivers' psychological well-being, and further well-designed multi-centre clustered randomized controlled trials could be considered to strengthen the evidence.     

Evidence of Generalized Muscle Stiffness in the Presence of Latent Trigger Points Within Infraspinatus

Objective

To evaluate stiffness of infraspinatus muscle tissue, both with and without latent trigger points, using ultrasound shear wave elastography (SWE). The primary hypothesis is that muscle with a latent trigger point will demonstrate a discrete region of increased shear wave speed. The secondary hypothesis is that shear wave speed (SWS) in the region with the trigger point will be higher in patients compared with controls, and will be similar between the two groups in the uninvolved regions.

Performance,reliability and fatigue in prone bridge test and supine unilateral bridge test

IntroductionThe core muscles can be evaluated through functional tests, such as the prone bridge test (PBT) and supine unilateral bridge test (SUBT). However, there are differences in reliability and muscle fatigue related to these tests.MethodsThe study evaluated 30 sedentary individuals and 30 individuals who practiced resistance exercises. Participants performed the PBT and SUBT in association with muscle recruitment, through surface electromyography of the upper and lower limbs and trunk muscles. The order of the tests was random and the participants performed one repetition of each test until fatigue. After a 30-min rest interval the participants repeated the tests. After one week, the participants returned and repeated the tests.ResultsThe resistance group (RG) presented longer PBT holding time (RG 111.8 ± 9.4 and sedentary group (SG) 81 ± 7.7; p = 0.01), while the holding time in the SUBT was similar for both groups (RG = 100.7 ± 8.1 and SG = 79 ± 9.2; p = 0.09). Good to excellent reliability (ICC >0.836; SEM < 3.85) was established for the PBT and SUBT. Comparing the two groups there were no significant differences or interactions regarding muscle fatigue. The intragroup analysis on the PBT indicated greater gluteus maximus muscle fatigue, and for the SUBT the rectus abdominis presented greater fatigue, in both groups.ConclusionThe PBT and SUBT are reliable. Resistance exercise practitioners maintain the PBT for a longer time. The PBT led to greater gluteus maximus muscle fatigue, while the SUBT generated greater fatigue in the rectus abdominis and gluteus medius, in both groups.     

Effect of myofascial release on lower limb range of motion,sit and reach and horizontal jump distance in male university students

ObjectiveEvaluate the effects of Myofascial release (MR) on lower limb ROM, sit and reach and horizontal jump distance in male university students.Study designQuasi-experimental study.BackgroundMR is a technique that aims to stretch fascia to increase range of motion (ROM), relieve pressure points and improve performance. However, there is limited evidence of its actual effects on flexibility and physical performance.MethodsTwenty-one uninjured, male university students received MR (11 on the first session and the other 10 on the second session 24 h later), completed lower limb ROM assessments, the sit and reach and the horizontal jump tests in a randomized order. MR was performed before the tests with a myofascial stick in the anterior and posterior aspects of the right and left thigh and calf muscles. Each muscle group was massaged for 90 s, totaling 9 min of MR. The testing conditions with MR and without MR were compared using Student t-tests and the effect sizes (ES) were calculated.ResultsThere were no significant differences between the testing conditions on horizontal jump distance. However, the sit and reach distance (28 ± 9 vs. 32 ± 9 cm, p = 0.001; ES = 0.44), left hip extension (10 ± 2 vs. 8 ± 2°, p = 0.006; ES = 1.00) and left plantar flexion (36 ± 7 vs. 39 ± 7°, p = 0.044; ES = 0.43) were higher with MR.ConclusionsMR increased sit and reach distance, left hip extension and plantar flexion, but it did not affect horizontal jump distance in uninjured, male university students.     

Dynamic changes in liver function after transjugular intrahepatic portosystemic shunt in patients with cirrhosis

PurposeTo evaluate the dynamic changes in liver function after transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with cirrhosis and to explore its association with clinical outcomes.MethodsThis retrospective study included patients who underwent TIPS between August 2016 and December 2020. Liver function was primarily evaluated using the model for end-stage liver disease (MELD) score, which was analyzed at baseline, 1 week, 1 month, 3 months, 6 months, and 12 months using one-way repeated measures ANOVA. The Kaplan-Meier method, log-rank test, and multivariate analysis were used as appropriate.ResultsIn total, 235 patients were included in this study. The MELD score was significantly higher at 1 week (11.8 ?± ?3.1 vs 13.5 ?± ?3.5, p ?< ?0.05) and 1 month (11.8 ?± ?3.1 vs 13.2 ?± ?4.6, p ?< ?0.05) than the baseline level and recovered at 3 months (11.8 ?± ?3.1 vs 11.9 ?± ?3.9, p ?> ?0.05). At 12 months, the MELD score was higher than the baseline level (11.8 ?± ?3.1 vs 12.4 ?± ?3.2, p ?< ?0.05). Patients with a recovery of the MELD score (n ?= ?151) at 3 months had a lower probability of overt and severe HE (log-rank p ?= ?0.015 and p ?= ?0.027, respectively) than those without recovery (n ?= ?84). Logistic regression analysis revealed that albumin (odds ratio [OR], 0.926; 95% confidence interval [CI], 0.863–0.992; p ?= ?0.029) and platelet count (OR, 0.993; 95% CI, 0.987–0.999; p ?= ?0.033) were independent predictive factors for non-recovery of the MELD score at 3 months.ConclusionsLiver function after TIPS creation showed a trend of deterioration at first, followed by recovery. Recovery of liver function at three months was associated with reduced overt and severe HE.     

Reliability of visual inspection and palpation to assess relative flexibility of the shoulder

IntroductionMovement compensations during internal rotation of the shoulder can provoke pain. Reliably observing and measuring compensations in the shoulder using visual and palpatory methods can result in more efficacious treatments of shoulder pathology. Despite this, the reliability of these measures and the relationship between them is unknown.MethodsBilateral shoulders of 33 Doctor of Physical Therapy (DPT) students were measured. Two third-year DPT student examiners used visual inspection and physical palpation to identify the first signs of internal rotation (IR) passive stiffness. Measurements were taken and recorded by a third examiner using the GetMyROM (Version 1.1) iPhone application.ResultsGood intra-rater reliability for both examiners was identified for physical palpation (ICC = 0.896, 95% CI = 0.830, 0.936, ICC = 0.901, 95% CI = 0.839, 0.939) and visual inspection (ICC = 0.813, 95% CI = 0.699, 0.884, ICC = 0.782, 95% CI = 0.667, 0.880). Moderate interrater reliability was found between the examiners for physical palpation (ICC = 0.681, 95% CI = 0.479, 0.797) while poor interrater reliability was found between examiners for visual inspection (ICC = 0.481, 95% CI = 0.234, 0.648). The correlation between physical palpation and visual inspection indicated moderate reliability for both examiners (r = 0.815, p = 0.01, r = 0.832, p = 0.01).ConclusionThe findings of this research study indicate that both physical palpation and visual inspection are reliable methods for measuring relative flexibility of shoulder IR when performed by the same examiner. However, the reliability for both methods decreases when performed by different examiners. Additionally, a strong correlation was found between both measures.     

Comparison of the postoperative pain change and spinal stenosis rate between percutaneous vertebroplasty combined with radiofrequency ablation and with 125I particle implantation in the treatment of metastatic spinal cord compression: A retrospective study

Background contextMetastatic spinal cord compression (MSCC) seriously affects the survival rate.ObjectiveThe therapeutic effects of two treatment strategies for MSCC: percutaneous vertebroplasty (PVP) combined with radiofrequency ablation (RFA) and PVP combined with ¹²⁵I particle implantation, were compared.Study designRetrospective study.Patient sample40 patients with MSCC were divided into two groups: 19 cases in the RFA group and 21 cases in the ¹²⁵I group.MethodAll patients were accessed to determine the differences in pain, which was evaluated using the visual analog scale (VAS) at 1 week, 1 month, and 3 months after the operation, and spinal stenosis rates (SSRs), which were measured at 1 and 3 months after the operation, between the two groups.ResultsThe VAS scores and SSRs at baseline were comparable between the RFA group and the ¹²⁵I group (7.19 ​± ​2.07 vs 7.42 ​± ​1.95, 37.7% ​± ​11.2% vs 41.1% ​± ​11.4%). The VAS scores and SSRs at 1 month and 3 months after the operation were significantly reduced in both groups, compared with those at baseline. The VAS scores and SSRs in the ¹²⁵I group were lower than those in the RFA group at 3 months after the operation (1.09 ​± ​0.97 vs 1.75 ​± ​1.06 p ​= ​0.048 and 12.3% ​± ​6.4% vs 18.1% ​± ​10.1% p ​= ​0.034), while the VAS scores at 1 week after the operation in the RFA group were lower than those in the ¹²⁵I group (4.39 ​± ​1.34 vs 5.05 ​± ​1.82 p ​= ​0.049).ConclusionPVP combined with RFA has a slight advantage in relieving pain in the short term, while PVP combined with ¹²⁵I particle implantation may have a better effect in the relieving pain and decreasing the SSRs at 3 months after the operation.     

Impact of the coronavirus disease 2019 pandemic on critical care healthcare workers' depression,anxiety, and stress levels

AimThe aim of the study was to determine levels of depression, anxiety, and stress symptoms and factors associated with psychological burden amongst critical care healthcare workers in the early stages of the coronavirus disease 2019 pandemic.MethodsAn anonymous Web-based survey distributed in April 2020. All healthcare workers employed in a critical care setting were eligible to participate. Invitations to the survey were distributed through Australian and New Zealand critical care societies and social media platforms. The primary outcome was the proportion of healthcare workers who reported moderate to extremely severe scores on the Depression, Anxiety, and Stress Scale-21 (DASS-21).ResultsOf the 3770 complete responses, 3039 (80.6%) were from Australia. A total of 2871 respondents (76.2%) were women; the median age was 41 years. Nurses made up 2269 (60.2%) of respondents, with most (2029 [53.8%]) working in intensive care units. Overall, 813 (21.6%) respondents reported moderate to extremely severe depression, 1078 (28.6%) reported moderate to extremely severe anxiety, and 1057 (28.0%) reported moderate to extremely severe stress scores. Mean ± standard deviation values of DASS-21 depression, anxiety, and stress scores amongst woman vs men was as follows: 8.0 ± 8.2 vs 7.1 ± 8.2 (p = 0.003), 7.2 ± 7.5 vs 5.0 ± 6.7 (p < 0.001), and 14.4 ± 9.6 vs 12.5 ± 9.4 (p < 0.001), respectively. After adjusting for significant confounders, clinical concerns associated with higher DASS-21 scores included not being clinically prepared (β = 4.2, p < 0.001), an inadequate workforce (β = 2.4, p = 0.001), having to triage patients owing to lack of beds and/or equipment (β = 2.6, p = 0.001), virus transmission to friends and family (β = 2.1, p = 0.009), contracting coronavirus disease 2019 (β = 2.8, p = 0.011), being responsible for other staff members (β = 3.1, p < 0.001), and being asked to work in an area that was not in the respondents' expertise (β = 5.7, p < 0.001).ConclusionIn this survey of critical care healthcare workers, between 22 and 29% of respondents reported moderate to extremely severe depression, anxiety, and stress symptoms, with women reporting higher scores than men. Although female gender appears to play a role, modifiable factors also contribute to psychological burden and should be studied further.     

Association between subscapularis trigger point and frozen shoulder: A cross sectional study

BackgroundFrozen shoulder (FS) is one of the most common shoulder conditions characterized by pain, restricted range of motion and high morbidity. Though FS is known as adhesive capsulitis, presence of capsular adhesions has been rebutted and the nomenclature adhesive capsulitis is debated. It has been proposed that FS is a condition of cytokine driven capsular, ligamentous fibrosis and contracture. Despite extensive research on it, still it is unclear that how far the capsular contracture contribute to range of motion restriction in FS. Evidence also suggested that myofascial trigger points play a role in restricted range of motion.ObjectiveTo find an association between subscapularis trigger point and frozen shoulder.Study designCross-sectional study.Method143 Patients were screened for inclusion and exclusion criteria, out of which 100 patients, were selected for the study. Manual palpation was performed to look for subscapularis muscle trigger points via axillary approach on both the affected and unaffected side. Trigger point diagnosing criteria was used to diagnose subscapularis trigger points.ResultsResults have shown that there was an association between subscapularis trigger point and frozen shoulder (X 2 = 32.151 P < 0.0001) on the affected side. We used Phi coefficient to measure the degree of association which denotes (Phi = 0.567 P < 0.0001) strong association between frozen shoulder and subscapularis trigger point on the affected side compared to unaffected side (X 2 9.157; P < 0.002: Phi:0.303: P < 0.002).ConclusionThis study concluded that there appears to be a strong association between subscapularis trigger point and frozen shoulder.     

Translation,cross-cultural adaptation,and measurement properties of the Brazilian-Portuguese version of the idiopathic pulmonary fibrosis-specific version of the Saint George's Respiratory Questionnaire (SGRQ-I) for patients with interstitial lung disease

BackgroundThe idiopathic pulmonary fibrosis-specific version of the St George's Respiratory Questionnaire (SGRQ-I) is a valid tool to assess health-related quality of life in patients with interstitial lung diseases (ILDs).ObjectiveTo translate and cross-culturally adapt the SGRQ-I to Brazilian-Portuguese, and to assess its measurement properties.MethodsPhase one consisted of the translation and cross-cultural adaptation of the questionnaire. In phase two, intra- and inter-assessor reliability (intraclass correlation coefficient [ICC]), internal consistency (Cronbach's α), minimal detectable change (MDC), ceiling/floor effects, convergent validity (correlation with SF-36 questionnaire), and discriminative validity (according to clinical characteristics) were investigated.ResultsNo significant adaptations were needed during the translation process of the SGRQ-I. In phase two, 30 patients with ILD were included (15 men; age 59 ± 10 years; Forced Vital Capacity 73 [61–80]%predicted). The total score on the SGRQ-I presented excellent intra-assessor (ICC: 0.93; 95%CI: 0.85, 0.97]) and inter-assessor (ICC: 0.88; 95%CI: 0.77, 0.94) agreement. Internal consistency was considered adequate for the domains impact, activity, and total score (0.79<α<0.88) but not for symptoms (α=0.43). MDC was 12.8 points and ceiling/floor effects were found in only 3% of patients. No discriminative validity was observed, but there was adequate convergent validity.ConclusionThe results provide preliminary evidence of adequate measurement properties and validity of the Brazilian-Portuguese version of the SGRQ-I for patients with ILDs.     

Comparing rehabilitation outcomes for patients admitted to the intensive care unit with COVID-19 requiring mechanical ventilation during the first two waves of the pandemic: A service evaluation

ObjectivesTo compare rehabilitation outcomes of patients admitted to the intensive care unit with COVID-19 and mechanically ventilated during wave 1 and 2, receiving two different models of physiotherapy delivery.MethodsAdults admitted to the intensive care unit between October–March 2021 (wave 2) with a confirmed diagnosis of COVID-19 and mechanically ventilated for >24 hours were included. During wave 2, rehabilitation was provided by physiotherapists over five days, with only emergency respiratory physiotherapy delivered at weekends. Rehabilitation status was measured daily using the Manchester Mobility Score to identify time taken to first mobilise and highest level of mobility achieved at ICU discharge. Outcomes were compared to data previously published from the same ICU during ‘wave 1’ (March–April 2020) when a seven-day rehabilitation physiotherapy service was provided.ResultsA total of n = 291 patients were included in analysis; 110 from wave 1, and 181 from wave 2. Patient characteristics and medical management were similar between waves. Mean ± SD time to first mobilise was slower in wave 2 (15 ± 11 days vs 14 ± 7 days), with overall mobility scores lower at both ICU (MMS 5 (Step transferring) vs MMS 4 (standing practice) (4), p < 0.05) and hospital (MMS 7 (Mobile > 30 m MMS) vs MMS 6 (Mobile < 30 m MMS), p < 0.0001) discharge. Significantly more patients in wave 2 required ongoing rehabilitation either at home or as an inpatient compared to wave 1 (81 % vs 49 %, p = 0.003).ConclusionThe change in physiotherapy staff provision from a seven-day rehabilitation service during wave 1 to a five day rehabilitation service with emergency respiratory physio only at weekends in wave 2 was associated with delayed time to first mobilise, lower levels of mobility at both intensive care unit and hospital discharge and higher requirement for ongoing rehabilitation at the point of hospital discharge.     

Measuring the physiological impact of extreme heat on lifeguards during cardiopulmonary resuscitation. Randomized simulation study

ObjectiveLifeguard teams carry out their work in extremely hot conditions in many parts of the world. The aim of this study was to analyze the impact of high temperatures on physiological parameters during cardiopulmonary resuscitation (CPR).MethodA randomized quasi-experimental cross-over design was used to test physiological lifesaving demands (50 min acclimatization +10 min CPR) in two different thermal environments: Thermo-neutral environment (25 °C) vs Hyperthermic environment (37 °C).ResultsThe data obtained from 21 lifeguards were included, this covers a total of 420 min of resuscitation. The CPR performance was constantly maintained during the 10 min. The Oxygen uptake (VO 2) ranged from 17 to 18 ml/min/kg for chest compressions (CC) and between 13 and 14 ml/min/kg for ventilations (V) at both 25 °C and 37 °C, with no significant difference between environments (p > 0.05). The percentage of maximum heart rate (%HR max) increased between 7% and 8% at 37 °C (p < 0.001), ranging between 75% and 82% of HR max. The loss of body fluids (LBF) was higher in the hyperthermic environment; LBF: (37 °C: 400 ± 187 g vs 25 °C: 148 ± 81 g, p < 0.001). Body temperature was 1 °C higher at the end of the test (p < 0.001). The perceived fatigue (RPE) increased by 37° an average of 2 points on a scale of 10 (p = 0.001).ConclusionsExtreme heat is not a limiting factor in CPR performance with two lifeguards. Metabolic consumption is sustained, with an increase in CC, so V can serve as active rest. Nevertheless, resuscitation at 37 °C results in a higher HR, is more exhausting and causes significant loss of fluids due to sweating.     

Comparison of the prevalence of myofascial trigger points of muscles acting on knee between patients with moderate degree of knee osteoarthritis and healthy matched people

IntroductionTrigger points have been implicated in the development of several musculoskeletal disorders. Trigger points harbored in lower limb muscles might represent a ubiquitous source of pain in patients with knee osteoarthritis (OA). This study was carried out to evaluate the prevalence of Myofascial Trigger Points (MTrPs) in muscles acting on the knee in patients with OA.MethodsThirty-seven patients aged at least 55 years old with a moderate degree of OA (grade III of Kellgren and Lawrence scale) were recruited. Thirty asymptomatic people, matched on age and body mass index, were considered as the control group. Ten muscles acting on the knee joint were selected. Taut bands were also identified using a skin rolling method. A pressure of 3 kg/cm² was used to identify myofascial trigger points in all muscles except the popliteus (8 kg/cm²).ResultsChi-square was performed to compare the prevalence of trigger points between the groups. The McNemar test was administered to compare the prevalence of trigger points in the right and left sides of participants. Prevalence of the trigger points was significantly higher in patients with knee OA compared with asymptomatic people in all muscles except for right (p = 0.17) and left (p = 0.41) rectus femoris, right (p = 0.61) and left (p = 0.22) sartorius and left biceps femoris (p = 0.08). Comparison of the prevalence of MTrPs bilaterally revealed that only the right and left sartorius differed significantly (p = 0.008).ConclusionsThe prevalence of MTrPs in the muscles acting on the knee joint is higher in patients with a moderate degree of knee OA compared with asymptomatic subjects.
