Body balance evaluation in osteoporotic elderly women

Summary

Osteoporotic Brazilian women balance was evaluated by timed up and go test (TUG) and to the Berg balance scale (BBS). In the BBS, women with and without osteoporosis had normal range scores, even with history of fall. In the TUG test, women with osteoporosis were slower, but in the normal parameter. Results suggest that the references values of these tests are not appropriate for Brazilians.

Purposes

The purposes of this study were to evaluate balance and functional mobility in women with osteoporosis and without osteoporosis and to verify if the history of falls has association to the TUG and to the BBS, both largely used in the clinical practice.

Materials and methods

Forty-five women were divided into three groups: group 1, young women with normal body mineral density (BMD); group 2, elderly with normal BMD; and group 3, elderly with osteoporosis. BBS and TUG were performed, and the history of falls was collected.

Results

BBS and TUG showed differences in the scores obtained for young women compared with both elderly with and without osteoporosis. In the TUG test, there were differences between elderly with and without osteoporosis. The fall’s history did not present correlations either for TUG or BBS.

Conclusions

Although the results showed that all women were within the normal range for BBS and TUG, the results suggest that the reference values for TUG and BBS are not appropriate for Brazilian population.     

The Structural Index Score and its relation to foot function,disability and physical performance tests in rheumatoid arthritis (RA) — A cross-sectional study

ObjectivesTo evaluate the Structural Index Score (SIS) – a clinical foot deformity assessment index developed for RA, and to compare its results with foot function, disability and physical performance tests.MethodsIn this cross-sectional study, 104 patients with foot pain were evaluated according to SIS score, subscales (Forefoot SIS and Rearfoot SIS) and items. Results were compared with the Foot Function Index (FFI), the Health Assessment Questionnaire Disability Index (using lower limbs items: LL-HAQ), and physical performance tests: Berg Balance Scale (BBS), the Timed Up and Go test (TUG) and the 5-Time Sit down-to-Stand up Test (SST5).ResultsThere was a weak correlation of SIS score with FFI and LL-HAQ. Rearfoot SIS was correlated with FFI, LL-HAQ and worse performance in BBS, TUG and SST5. Regarding Rearfoot SIS items, the ankle ROM was correlated to all studied outcomes, the calcaneus varus/valgus was correlated with FFI (total, pain and disability subscales) and the planus/cavus deformity with FFI-pain, HAQ-DI and LL-HAQ. Forefoot SIS did not correlate with any outcome measures. In relation to Forefoot SIS items, hallux valgus was associated with foot function (FFI-total, pain and disability subscales), the MTPs joints subluxation was correlated with FFI-disability subscale, and the 5th MTP exostosis was associated with FFI-pain.ConclusionSIS score was correlated to impaired foot function (FFI) and disability (LL-HAQ). Rearfoot SIS was correlated to worse performance on FFI, LL-HAQ, BBS, TUG and SST5. SIS score index can be a useful tool to evaluate the rheumatoid foot deformities, but a better graduation of foot deformities should add sensitivity to this method.     

Preoperative methylprednisolone does not reduce loss of knee-extension strength after total knee arthroplasty

Background and purpose — Patients undergoing total knee arthroplasty (TKA) face challenges related to postoperative reduction in knee-extension strength. We evaluated whether inhibition of the inflammatory response by a single preoperative dose of methylprednisolone (MP) reduces the pronounced loss of knee-extension strength at discharge after fast-track TKA.

Patients and methods — 70 patients undergoing elective unilateral TKA were randomized (1:1) to preoperative intravenous (IV) MP 125?mg (group MP) or isotonic saline IV (group C). All procedures were performed under spinal anesthesia without tourniquet, and with a standardized multimodal analgesic regime. The primary outcome was change in knee-extension strength from baseline to 48?hours postoperatively. Secondary outcomes were knee joint circumference, functional performance using the Timed Up and Go (TUG) test, pain during the aforementioned tests, rescue analgesic requirements, and plasma C-reactive protein (CRP) changes.

Results — 61 patients completed the follow-up. The loss in quadriceps muscle strength was similar between groups; group MP 1.04 (0.22–1.91) Nm/kg (–89%) vs. group C 1.02 (0.22–1.57) Nm/kg (–88%). Also between-group differences were similar for knee circumference, TUG test, and pain scores. MP reduced the inflammatory response (CRP) at 24?hours postoperatively; group MP 33 (IQR 21–50) mg/L vs. group C 72 (IQR 58–92) mg/L (p < 0.001), and 48?hours postoperatively; group MP 83 (IQR 56–125) mg/L vs. group C 192 (IQR 147–265) mg/L (p < 0.001), respectively.

Interpretation — Preoperative systemic administration of MP 125?mg did not reduce the pronounced loss of knee-extension strength or other functional outcomes at discharge after fast-track TKA despite a reduced systemic inflammatory response.     

Predicting the probability of falls in community dwelling persons with brain injury: a pilot study

PRIMARY OBJECTIVES: To determine the usefulness of select balance and functional mobility measures in predicting fall risk in community dwelling persons with brain injury (BI) and to develop a model to quantify fall risk. RESEARCH DESIGN: An exploratory pilot study to predict fall risk in persons with BI. Non-manipulated independent variable was fall status with two levels, non-faller and faller. Dependent variables were scores on the Berg Balance Scale (BBS), the Dynamic Gait Index (DGI) and the Falls Efficacy Scale (FES); age, gender, supervision required and assistive device use. METHODS AND PROCEDURES: Twenty-six participants recruited from support groups and community re-entry programmes were divided into two groups, fallers and non-fallers. The FES, BBS and DGI were administered. MAIN OUTCOMES AND RESULTS: T-tests and chi-square tests revealed between group differences for age, FES, BBS, DGI and assistive device use. Spearman's rho statistic showed moderate relationships among the variables, FES, BBS, DGI and assistive device use. Logistic regression determined the DGI to best predict fall risk. CONCLUSIONS: This study developed a predictive model that could be used by therapists to determine an individual's fall risk in the home or outpatient settings. Assessing risk allows therapists to identify individuals who would benefit from intervention designed to improve balance and gait ability, possibly preventing future falls and a second head injury.

The effects of semi-immersive virtual reality therapy on standing balance and upright mobility function in individuals with chronic incomplete spinal cord injury: A preliminary study

Background: Individuals with chronic incomplete spinal cord injury (iSCI) commonly face persistent balance or mobility impairments. Virtual reality (VR) therapy is a useful rehabilitation approach; however, little is known about its effects in individuals with chronic iSCI.

Objective: To investigate the effects of semi-immersive VR therapy on standing balance and upright mobility function in individuals with chronic iSCI.

Methods: Ten subjects with chronic iSCI underwent VR therapy 30 minutes a day, 3 days a week, for 6 weeks. Limit of stability (LOS) and the Berg Balance Scale (BBS) were used to evaluate standing balance function. The Timed Up & Go (TUG) test, Activities-specific Balance Confidence (ABS) Scale, and Walking Index for Spinal Cord Injury-II (WISCI-II) were used to measure the subject’s upright mobility function. Outcomes were assessed and recorded pre- and post-intervention.

Results: After semi-immersive VR therapy, LOS and BBS scores were significantly increased. In addition, the TUG test results increased significantly over time, while ABC scale scores and WSCI-II levels improved significantly.

Conclusion: This study is the first to assess the effects of semi-immersive VR therapy for patients with chronic iSCI and limited functional abilities. These results indicated that semi-immersive VR therapy has a positive effect and is a useful intervention for standing balance and upright mobility function in patients with chronic iSCI.     

A comparison of the effectiveness of splinting,exercise and electrotherapy in women patients with hallux valgus: A randomized clinical trial

BackgroundHallux valgus (HV) is a very common foot deformity involving lateral deviation of the hallux and medial deviation of the first metatarsal head.ObjectivesTo investigate the effects of HV night splinting, exercise and electrotherapy on the HV angle, and foot-specific health-related quality of life.MethodsSixty women (120 feet) with bilateral HV deformity were randomly assigned to one of three groups — an HV night splint (SP) group, an exercise (EX) group, and a high-voltage galvanic stimulation (HVPGS) (EL) group. The patients in SP group used the HV night splints while resting or sleeping for at least 8 h a day and the patients in the EX group performed exercises 3–4 times a day with 10 repetitions for the duration of the one-month treatment period. Twenty-minute HVPGS was applied in total over three weekly sessions for four weeks in EL group. Angular degrees (hallux interphalangeal angle (HIPA), HV angle (HVA), and intermetatarsal angle (IMA)) were determined before (t0) and three months after treatment (t2). Foot-specific quality of life was assessed using the Manchester-Oxford Foot Questionnaire (MOFQ) at t0, after one month (t1), and at t2.ResultsAll groups exhibited significant changes in the HIPA, HVA, and IMA angles and outcome measures (p ≤ 0.001). Decreases in the HIPA and IMA angles, and MOFQ-Pain subscale scores, were higher in the SP group than in the other two groups (p < 0.05). IMA angle at t2, MOFQ-Walking score at t1 and t2 and MOFQ-Pain subscale score at t1 were lower in the SP group (p < 0.05).ConclusionThe SP group exhibited more positive effects in the parameters measured than the other two groups. A combination of these conservative treatment approaches may be more beneficial to improve HV symptoms with longer follow-up periods.ClinicalTrials.gov IdentifierNCT04393545.     

Quadriceps muscle characteristics and subcutaneous fat assessed by ultrasound and relationship with function in patients with knee osteoarthritis awaiting knee arthroplasty

BackgroundPatients with severe knee osteoarthritis are evaluated for total knee replacement (TKR), whose main indications are persistent pain and severe functional limitations substantially affecting mobility. However, evaluation of pain intensity and functional disability is difficult to standardize.ObjectiveTo evaluate the relationship between quadriceps muscle thickness (QMT) and quality; the QMT and subcutaneous fat thickness (SFT) and QMT and function in patients with knee OA on a waiting list for TKR.MethodsCross-sectional study in consecutively-enrolled patients. Variables: SFT, QMT and rectus femoris muscle quality, assessed by echointensity (EI). Function by the Timed Up & Go Test (TUG); sociodemographic and clinical variables and physical activity were determined. Karl Pearson correlations and multiple linear regression were used.Results61 patients (45 female, mean age 69.7 years [SD 7.2], mean BMI 33.0 [SD 5.7], mean comorbidities 3.3 [SD 2.0], 52.5% regular physical activity) were studied. Mean TUG was 15.1 (SD 6.1). Variables retained in the regression model explained 36% of variability in the TUG. Greater muscle content (percentage) (r = −0,291) was associated with better TUG scores (p = 0.001). Greater muscle EI was negatively (r = −0,364) associated with function (p = 0.006). Older age was associated with worse TUG scores while regular physical activity was associated with better TUG scores (p = 0.001 and p = 0.008, respectively).ConclusionsA higher percentage of quadriceps muscle and better muscle quality (lower EI) was associated with better function. Age and exercise levels influenced function. Ultrasound may provide     

Efficacies of extracorporeal shockwave therapy and low-level laser therapy in patients with plantar fasciitis

BackgroundVarious conservative treatment methods can be administered in the early stages of plantar fasciitis (PF). The aim of the treatment is to enable the patient to return to the physical activity as soon as possible.AimIn this study it was aimed to compare efficacies of Extracorporeal Shockwave Therapy (ESWT) and Low-Level Laser Therapy (LLLT) on patients with PF.DesignA local prospective cross-sectional studySettingDepartment of Physical Medicine and Rehabilitation Outpatient Clinic of Sakarya University, Faculty of MedicinePopulationPatients aged 18–70 years, having ongoing heel pain for at least 3 months, and not using oral and/or parenteral corticosteroids in the last 6 months.MethodsA total of 40 patients with PF included in the current study. Visual Analog Scale (VAS), Roles and Maudsley Score (RMS), American Orthopedic Foot and Ankle Association Score (AOFAS) and Foot Function Index (FFI) questionnaire were performed for all patients. ESWT and LLLT groups comprised of 22 (55%) and 18 (45%) patients, respectively.ResultsWe found significant improvements in scores based on the VAS, RMS, AOFAS, FFI in patients with PF and it was sustained for 3 months (p = 0.001, for all scores). While decrease in scores based on the VAS and FFI in LLLT group was statistically more significant compared to ESWT group (p = 0.014, p = 0.013), there was statistically less significant decrease in scores on the AOFAS in LLLT group than that of ESWT group (p = 0.032).ConclusionsThe results of this study indicated significant improvements in terms of pain, functional status and daily life activities following the administration of either of the treatments. Furthermore, LLLT was found to be significantly more effective for alleviating pain than ESWT in the treatment of PF.     

The impact of hallux valgus on function and quality of life in females

BackgroundThe effect of hallux valgus (HV) on health-related quality of life (HRQOL) and the relationship between radiographic severity of deformity and patient reported outcome measures (PROMs) is poorly understood.The aim of this study was to compare the HRQOL of female patients with HV to the UK population. The secondary aim was to assess the correlation between PROMs, including HRQOL, with radiographic severity of deformity.MethodsWeight bearing radiographic data (hallux valgus (HVA) angle; intermetatarsal (IM) angle) were measured in consecutive female patients presenting with HV. Each patient prospectively completed the Euroqol EQ-5D-5L questionnaire (EQ-5D), Visual Analogue Scale for Pain (VAS-Pain) and Manchester Oxford Foot Questionnaire (MOXFQ). Data were stratified into age ranges and compared with an EQ-5D United Kingdom general population reference dataset. Pearson R correlation values were calculated for the PROMs and radiographic deformity.ResultsBetween July 2015 and March 2020, 425 consecutive female patients presented with HV for consideration for surgery. EQ-5D-5L data were prospectively collected for 396 of these patients (93.2%). Females less than 65 years with HV had a statistically significantly worse quality of life compared with females of the same age group in the general population. Above the age of 65, there was no statistically significant difference in EQ-5D-5L Index score between the two groups. Younger females reported higher VAS-Pain scores compared to older patients with 91% of patients reporting some degree of pain symptoms. There was a moderate correlation with MOXFQ Index score and EQ-5D-5L Index (R = ?0.51, p < 0.001) and VAS-Pain scores (R = 0.54, p < 0.001). There was no correlation between radiographic HV deformity and HRQOL measures or MOXFQ scores although it was noted that there was a trend of increasing HVA/IMA with age.ConclusionFemale patients presenting with HV deformity have a significantly reduced quality of life compared with the UK general population. The radiographic severity of deformity did not correlate with HRQOL measures or foot and ankle specific PROMs. Foot and ankle specific clinical PROMsmoderately correlate with HRQOL and may be a better marker of the negative effect of symptomatic hallux valgus deformity on quality of life.Level of evidenceIII     

Quality of life in individuals with chronic foot conditions: A cross sectional observational study

BackgroundChronic foot conditions have been reported to be a significant cause of impairment and disability to individuals affected. However, studies to date have particularly focussed on patient satisfaction with outcomes following surgery.ObjectivesThe aim of this study is to examine the impact of three common foot conditions on the levels of impairment and quality of life prior to surgery. Three conditions include Hallux Valgus (HV), Hallux Rigidus (HR) and Hammer Toe (HT).MethodsThis was a pilot cross-sectional observational study of people who were radiologically and clinically diagnosed with one of the three common foot pathologies: HV, HR and HT. Age and gender matched controls were also recruited. Self-reported quality of life was measured.ResultsThe SF-36 scores did not differ significantly between the groups. There was a significant difference in self reported impairment between the groups on the Global Foot and Ankle Scale indicating that the ‘bilateral foot group’ perceived themselves to be significantly more impaired than their counterparts in the control group.ConclusionPatient quality of life is now recognised as one of the most important outcomes of surgery. These findings serve to highlight the level of impairment and quality of life of individuals prior to surgery.     

A clinically meaningful training effect in walking speed using functional electrical stimulation for motor-incomplete spinal cord injury

Context/Objective: The study aimed to investigate the presence of a training effect for rehabilitation of walking function in motor-incomplete spinal cord injury (SCI) through daily use of functional electrical stimulation (FES).

Setting: A specialist FES outpatient centre.

Participants: Thirty-five participants (mean age 53, SD 15, range 18-80; mean years since diagnosis 9, range 5 months - 39 years) with drop foot and motor-incomplete SCI (T12 or higher, ASIA Impairment Scale C and D) able to ambulate 10 metres with the use of a walking stick or frame.

Interventions: FES of the peroneal nerve, glutei and hamstrings as clinically indicated over six months in the community.

Outcome Measures: The data was analysed for a training effect (difference between unassisted ten metre walking speed at baseline and after six months) and orthotic effects (difference between walking speed with and without FES) initially on day one and after six months. The data was further analysed for a minimum clinically important difference (MCID) (>0.06 m/s).

Results: A clinically meaningful, significant change was observed for initial orthotic effect (0.13m/s, CI: 0.04-0.17, P?=?0.013), total orthotic effect (0.11m/s, CI: 0.04-0.18, P?=?0.017) and training effect (0.09m/s, CI: 0.02-0.16, P?=?0.025).

Conclusion: The results suggest that daily independent use of FES may produce clinically meaningful changes in walking speed which are significant for motor-incomplete SCI. Further research exploring the mechanism for the presence of a training effect may be beneficial in targeting therapies for future rehabilitation.     

Colonoscopy performance correlates with scores on the FES™ manual skills test

Introduction

Achieving proficiency in flexible endoscopy is a major priority for general surgery training programs. The Fundamentals of Endoscopic Surgery (FES?) is a high-stakes examination of the knowledge and skills required to perform flexible endoscopy. The objective of this study was to establish additional evidence for the validity of the FES? hands-on test as a measure of flexible endoscopy skills by correlating clinical colonoscopy performance with FES? score.

Methods

Participants included FES?-naïve general surgery residents, gastroenterology fellows at all levels of training and attending physicians who regularly perform colonoscopy. Each participant completed a live colonoscopy and the FES? hands-on test within 2 weeks. Performance on live colonoscopy was measured using the Global Assessment of Gastrointestinal Endoscopic Skills—Colonoscopy (GAGES-C, maximum score 20), and performance on the FES? hands-on test was assessed by the simulator’s computerized scoring system. The clinical assessor was blinded to simulator performance. Scores were compared using Pearson’s correlation coefficient.

Results

A total of 24 participants were enrolled (mean age 30; 54 % male) with a broad range of endoscopy experience; 17 % reported no experience, 54 % had <25 previous colonoscopies; and 21 % had >100. The FES? and GAGES scores reflected the broad range of endoscopy experience of the study group (FES? score range 32–105; GAGES score range 5–20). Pearson’s correlation coefficient between GAGES-C scores and FES? hands-on test scores was 0.78 (0.54–0.90, p < 0.0001). All eight participants with GAGES-C score >15/20 achieved a passing score on the FES? hands-on test.

Conclusion

There is a strong correlation between clinical colonoscopy performance and scores achieved on the FES? hands-on test. These data support the validity of FES? as a measure of colonoscopy skills.     

The effect of single-task and dual-task balance exercise programs on balance performance in adults with osteoporosis: a randomized controlled preliminary trial

Summary

Osteoporosis is a serious disease characterized by muscle weakness in the lower extremities, shortened length of trunk, and increased dorsal kyphosis leading to poor balance performance. Although balance impairment increases in adults with osteoporosis, falls and fall-related injuries have been shown to occur mainly during the dual-task performance. Several studies have shown that dual-task performance was improved with specific repetitive dual-task exercises.

Introduction

The aims of this study were to compare the effect of single- and dual-task balance exercise programs on static balance, dynamic balance, and activity-specific balance confidence in adults with osteoporosis and to assess the effectiveness of dual-task balance training on gait speed under dual-task conditions.

Methods

Older adults (N = 42) (age range, 45–88 years) with osteoporosis were randomly assigned into two groups. Single-task balance training group was given single-task balance exercises for 4 weeks, whereas dual-task balance training group received dual-task balance exercises. Participants received 45-min individualized training session, three times a week. Static balance was evaluated by one-leg stance (OLS) and a kinesthetic ability trainer (KAT) device. Dynamic balance was measured by the Berg Balance Scale (BBS), Time Up and Go (TUG) test, and gait speed. Self-confidence was assessed with the Activities-specific Balance Confidence (ABC-6) scale. Assessments were performed at baseline and after the 4-week program.

Results

At the end of the treatment periods, KAT score, BBS score, time in OLS and TUG, gait speeds under single- and dual-task conditions, and ABC-6 scale scores improved significantly in all patients (p?<?0.05). However, BBS and gait speeds under single- and dual-task conditions showed significantly greater improvement in the dual-task balance training group than in the single-task balance training group (p?<?0.05). ABC-6 scale scores improved more in the single-task balance training group than in the dual-task balance training group (p?<?0.05).

Conclusions

A 4-week single- and dual-task balance exercise programs are effective in improving static balance, dynamic balance, and balance confidence during daily activities in older adults with osteoporosis. However, single- and dual-task gait speeds showed greater improvement following the application of a specific type of dual-task exercise programs.

Comparison of transcutaneous electrical nerve stimulation (TENS) and functional electrical stimulation (FES) for spasticity in spinal cord injury - A pilot randomized cross-over trial

Objective: Spasticity following spinal cord injury (SCI) can impair function and affect quality of life. This study compared the effects of transcutaneous electrical nerve stimulation (TENS) and functional electrical stimulation (FES) on lower limb spasticity in patients with SCI.

Design: Double blind randomized crossover design.

Setting: Neuro-rehabilitation unit, Manipal University, India.

Participants: Ten participants (age: 39 ± 13.6 years, C1–T11, 1–26 months post SCI) with lower limb spasticity were enrolled in this study.

Interventions: Participants were administered electrical stimulation with TENS and FES (duration - 30 minutes) in a cross over manner separated by 24 hours.

Outcome Measures: Spasticity was measured using modified Ashworth scale (MAS) [for hip abductors, knee extensors and ankle plantar flexors] and spinal cord assessment tool for spastic reflexes (SCATS). Assessments were performed at baseline, immediately, 1 hour, 4 hours, and 24 hours post intervention.

Results: A between group analysis did not show statistically significant differences between FES and TENS (P > 0.05). In the within group analyses, TENS and FES significantly reduced spasticity up to 4 hours in hip adductors and knee extensors (P < 0.01). SCATS values showed significant reductions at 1 hour (P?=?0.01) following TENS and 4 hours following FES (P?=?0.01).

Conclusion: A single session of electrical stimulation with FES and TENS appears to have similar anti-spasticity effects that last for 4 hours. The findings of this preliminary study suggest that both TENS and FES have the potential to be used as therapeutic adjuncts to relieve spasticity in the clinic. In addition, FES may have better effects on patients presenting with spastic reflexes.     

Novel values in the radiographic diagnosis of ligamentous Lisfranc injuries

BackgroundLigamentous Lisfranc instability is commonly missed on unilateral radiographs. However, measurement protocols for bilateral weightbearing radiographs have not been standardized. The primary aim of this study was to investigate the optimal cut-off values for diagnosing Lisfranc instability by evaluating the side-to-side differences of preoperative bilateral weightbearing radiographs among patients with surgically-confirmed ligamentous Lisfranc instability. A secondary aim was to investigate whether the midfoot measurements for detecting Lisfranc injury could also be used in patients with a pre-existing bilateral Hallux Valgus (HV) deformity by evaluating whether the Lisfranc measurements could be affected by a foot deformity as HV.Patients and methodsPatients who underwent surgical repair of ligamentous Lisfranc instability, as well as a separate cohort with bilateral hallux valgus deformity, were included in this multicenter retrospective cohort study. A standardized radiographic measurement protocol was used to assess the midfoot and a receiver operator correlation (ROC) analysis was used to identify the optimal cut-off value for measurements. Interclass Correlation (ICC) scores were calculated to assess the interrater reliability of the Lisfranc area measurement.ResultsForty-seven patients were included in the Lisfranc group with a mean age of 33 (± 15) years and 25 patients were included in the HV group with a mean age of 51 (± 15) years. For the Lisfranc group, measurements that demonstrated a significant side-to-side difference included; increased C1M2 diastasis of 2.4 mm (± 1.4, P<0.001), increased C1M2 surface area of 24 mm² (± 15, P<0.001), C2M2 malignment by 1.7 mm (± 1.2, P<0.001), second tarsometatarsal joint dorsal step-off sign by 0.8 mm (± 0.7, P<0.001), and arch height by 2.5 mm (± 6.4, P<0.048), all greater on the injured side. In the HV group, side-to-side measurements were not significantly different. There was no significant difference comparing the M1M2 measurement in the HV group with the injured (P = 0.16) or uninjured (P = 0.08) foot in the Lisfranc group. The optimal cut-off points were between the injured and uninjured foot in the Lisfranc group were 2.1 mm for C1M2 diastasis, 0.7 mm for the C2M2 alignment, and 30 mm² for the C1M2 surface area. The ICC-score for the second C1M2 area measurement was 0.88.ConclusionBilateral foot weightbearing radiographs can effectively diagnose ligamentous Lisfranc instability using a standardized measurement protocol. Malalignment of the medial aspect of the second metatarsal base ≥0.3 mm relatively to the intermediate cuneiform offers a high sensitivity, and distance ≥2.1 mm between the second metatarsal base and the medial cuneiform has a high specificity. Intermetatarsal distance between the first and second metatarsal base has a low sensitivity and specificity and should not be used in solitary for diagnosis.Level of evidenceLevel III, retrospective comparative study     

Lower extremity functional electrical stimulation cycling promotes physical and functional recovery in chronic spinal cord injury

Abstract

Objective

To examine the effect of long-term lower extremity functional electrical stimulation (FES) cycling on the physical integrity and functional recovery in people with chronic spinal cord injury (SCI).

Design

Retrospective cohort, mean follow-up 29.1 months, and cross-sectional evaluation.

Setting

Washington University Spinal Cord Injury Neurorehabilitation Center, referral center.

Participants

Twenty-five people with chronic SCI who received FES during cycling were matched by age, gender, injury level, and severity, and duration of injury to 20 people with SCI who received range of motion and stretching.

Intervention

Lower extremity FES during cycling as part of an activity-based restorative treatment regimen.

Main outcome measure

Change in neurological function: motor, sensory, and combined motor–sensory scores (CMSS) assessed by the American Spinal Injury Association Impairment scale. Response was defined as ≥1 point improvement.

Results

FES was associated with an 80% CMSS responder rate compared to 40% in controls. An average 9.6 CMSS point loss among controls was offset by an average 20-point gain among FES subjects. Quadriceps muscle mass was on average 36% higher and intra/inter-muscular fat 44% lower, in the FES group. Hamstring and quadriceps muscle strength was 30 and 35% greater, respectively, in the FES group. Quality of life and daily function measures were significantly higher in FES group.

Conclusion

FES during cycling in chronic SCI may provide substantial physical integrity benefits, including enhanced neurological and functional performance, increased muscle size and force-generation potential, reduced spasticity, and improved quality of life.     

Preoperative photography improves patient satisfaction following hallux valgus surgery

BackgroundPatient satisfaction is variable following hallux valgus (HV) surgery. This prospective, blinded, randomized trial endeavored to determine whether showing patients a preoperative photograph would improve satisfaction following HV corrective surgery.MethodsAdult patients undergoing HV surgery were randomized to a picture group (P) or a no picture group (NP). P-group patients were shown their preoperative photograph for 5 min at each postoperative visit. Outcome measures included the Foot Function Index (FFI), the Foot Ankle Outcome Score (FAOS), and a patient satisfaction questionnaire.ResultsTwenty-nine patients were enrolled in the study (15P, 14 NP). At 3, and 6 months postoperatively, patients in the P-group were more likely to be completely satisfied with the appearance of their foot. There were no differences between groups with respect to postoperative HVA, IMA, or FFI, and FAOS scores.ConclusionPatient satisfaction is increased following hallux valgus corrective surgery by reminding patients of the preoperative appearance of their foot through the use of photographs.Level of EvidenceLevel I, randomized control trial.     

Quantitative assessment of postural balance in patients with chronic anterior cruciate ligament injury- A controlled study

PurposeEvaluation of single and double limb support postural balance in patients with Anterior cruciate ligament (ACL)injury and comparison of the postural strategy adopted after ACL injury/deficiency(ACLD) with that of an age-matched healthy individual.MethodsThe study group that included 33 subjects confirming inclusion criteria had undergone postural balance assessment using the HUMAC Balance system. The parameters of the center of pressure excursion were recorded on a force plate and compared with age, BMI matched 66 healthy volunteers of control group. The center of pressure excursions was monitored using dependable variables such as sway path length(cm), the average velocity of sway(cm/sec), and the mean COP stability score(%). The mobility component was recorded as the percentage (%) of time spent on each target.ResultA decrease in postural balance in the injury group was evidenced by a statistically significant decrease of stability score(p = 0.015), increase in path length(p = 0.002) and decrease on time on target mean score (p= <0.001),. Although, the stability score path length and average sway velocity scores in the sound limb of the ACLD group showed impaired balance, the differences were not statistically significant (p = 0.180, p = 0.561, and p = 0.639 respectively) when compared with the dominant limb of the control group.ConclusionHUMAC balance system is an effective and simplified measure for quantifying postural balance. Although overall postural stability in ACL injury is impaired, static postural balance is maintained by the compensatory of strategy of sound limb. However, the quantitative parameters of postural stability for the sound limb, despite of a lower mean value, did not show statistically significant differences from the dominant limb of the controlled group.     

Bilateral and concomitant pathology’ surgeries do not affect the outcomes of mini-open distal linear metatarsal osteotomy (Bosch osteotomy) with manipulation for hallux valgus deformity

BackgroundBosch osteotomy for hallux valgus (HV) deformity has advantages of reduction both the operating time and surgical dissection, and may be performed bilaterally and with fewer complications than other surgical procedures as well as early weight-bearing. However, there are few reports on the effects of bilateral simultaneous surgery, simultaneous surgery on concomitant pathologies, and the preoperative HV angle on the postoperative results. The present assessed the factors that might affect the improvement in clinical outcomes following mini-open Bosch osteotomy with manipulation to treat HV deformity.MethodsSeventy patients with 110 feet were included. They were divided into groups as follows: unilateral and bilateral simultaneous surgery groups, Bosch osteotomy alone and simultaneous surgeries for concomitant pathologies groups, and preoperative HV angle< 40° and ≥ 40° groups. Subjective clinical outcome scores using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and the HV and intermetatarsal first and second metatarsal (M1M2) angles according to the anteroposterior (A-P) view of the weighted foot X-ray were assessed preoperatively and at 12 months after surgery.ResultsThe mean HV angle, M1M2 angle and all subscales of the SAFE-Q score showed significant improvement at 12 months after surgery, regardless of simultaneous bilateral surgery, simultaneous surgery for concomitant pathologies, or the preoperative HV angle. On comparing the groups, there were no significant differences in the HV angle at 12 months after surgery. Significant inferiority at 12 months after surgery was found in the intermetatarsal angle in the simultaneous surgery for concomitant pathologies group and in all subscales of the SAFE-Q score in the HV angle ≥ 40° group.ConclusionMini-open Bosch osteotomy with manipulation for HV deformity demonstrated good results in both radiological assessments and subjective clinical scores at 12 months after surgery, even for simultaneous bilateral surgery, simultaneous concomitant pathologies’ surgery, and severe HV deformity.Level of EvidencePrognostic Level III, retrospective cohort study.
