Calculation of the minimal clinically important difference in operated patients with adult spine deformity: advantages of the ROC method and significance of prevalence in threshold selection

PURPOSE

The Minimal Clinically Important Difference (MCID) is crucial to evaluate management outcomes, but different thresholds have been obtained in different works. Part of this variability is due to measurement error and influence of the database, both essential for calculating the MCID. The aim of this study was to introduce the association of the ROC method in the anchor-based MCID calculation for ODI, SRS-22r, and SF-36, to objectively set the threshold for the anchor-based MCID in an adult spine deformity (ASD) population.

METHODS

Multicentric study based on a prospective database of consecutively operated ASD patients. An anchor question was used to assess patients' quality of life after surgery. Different approaches were used to calculate the MCID and then compared: SEM (Standard Error of Measurement), MDC (Minimal Detectable Change), and anchor-based MCID with ROC method.

RESULTS

516 patients were included. Those who responded with 6 and 7 to the anchor question were considered improved. The MCID ranges obtained with the ROC method exhibited the lowest variability. Prediction error rates ranged from 31% (SRS-22r) to 41% (SF-36 MCS). The MCID ranges spanned between 12 and 15 for ODI, 0.6 and 0.73 for SRS-22r, 6.62 and 7.41 for SF-36 PCS, and between 2.69 and 5.63 for SF-36 MCS.

CONCLUSION

The ROC method proposes an MCID range with error rate, and can objectively determine the threshold for distinguishing improved and non-improved patients. As the MCID correlates with the utilized database and error of measurement, each study should compute its own MCID for each PROM to allow comparison among different publications.

Novel Posterior Shoulder Stretching With Rapid Eccentric Contraction and Static Stretching in Patients With Subacromial Pain Syndrome: A Randomized Trial

BACKGROUND

In subacromial pain syndrome (SPS), it is unknown whether posterior shoulder stretching exercises (PSSE) with rapid eccentric contraction, a muscle energy technique, improve clinical and ultrasonographic outcomes more than no stretching or static PSSE.

HYPOTHESIS

PSSE with rapid eccentric contraction is superior to no stretching and static PSSE in improving clinical and ultrasonographic outcomes in SPS.

STUDY DESIGN

Randomized controlled trial.

LEVEL OF EVIDENCE

Level 1.

METHODS

Seventy patients with SPS and glenohumeral internal rotation deficit were randomized into the modified cross-body stretching with rapid eccentric contraction group (EMCBS; n = 24), static MCBS group (SMCBS; n = 23), or control group (CG; n = 23). In addition to 4-week physical therapy, EMCBS received PSSE with rapid eccentric contraction, SMCBS static PSSE, and CG no PSSE. The primary outcome was internal rotation range of motion (ROM). Secondary outcomes were posterior shoulder tightness, external rotation ROM (ERROM), pain, modified Constant-Murley score, short form of the disabilities of the arm, shoulder, and hand questionnaire (QuickDASH), rotator cuff strength, acromiohumeral distance (AHD), supraspinatus tendon thickness, and supraspinatus tendon occupation ratio (STOR).

RESULTS

Shoulder mobility, pain, function and disability, strength, AHD, and STOR improved in all groups (P < 0.05).

CONCLUSION

In patients with SPS, PSSE with rapid eccentric contraction and static PSSE were superior to no stretching in improving clinical and ultrasonographic outcomes. Stretching with rapid eccentric contraction was not superior to static stretching, but improved ERROM compared with no stretching.

CLINICAL RELEVANCE

In SPS, both PSSE with rapid eccentric contraction and static PSSE included in physical therapy program are beneficial to improve posterior shoulder mobility and other clinical and ultrasonographic outcomes. In the case of ERROM deficiency, rapid eccentric contraction might be preferred.

Prevalence, diagnostic delay and economic burden of endometriosis and its impact on quality of life: results from an Eastern Mediterranean population

BACKGROUND

There are limited data on endometriosis from the Eastern Mediterranean region. This study for the first time estimates the prevalence and impact of endometriosis on women in Northern Cyprus, an under-represented region in Europe.

METHODS

Cyprus Women's Health Research Initiative, a cross-sectional study recruited 7646 women aged 18-55 in Northern Cyprus between January 2018 and February 2020. Cases were identified using self-reported and ultrasound data and two control groups were defined, with (n = 2922) and without (n = 4314) pain. Standardized tools, including the 11-point Numerical Rating Scale and the Short Form 36 Health Survey version 2, were used to assess pain and quality of life, respectively.

RESULTS

Prevalence and median diagnostic delay of endometriosis were 5.4% [95% confidence interval (CI): 4.9-5.9%, n = 410] and 7 (interquartile range 15.5) years. Endometriosis cases experienced a higher prevalence of bladder pain compared with asymptomatic pain controls (6.3% vs. 1.0%, P < 0.001) and irritable bowel syndrome relating to pelvic pain compared with symptomatic (4.6% vs. 2.6%, P = 0.027) and asymptomatic (0.3%, P < 0.001) controls. The odds of endometriosis cases reporting an anxiety diagnosis was 1.56 (95% CI: 1.03-2.38) higher than the symptomatic and 1.95 (95% CI: 1.30-2.92) times higher than the asymptomatic controls. The physical component score of the health-related quality-of-life instrument suggested a significant difference between the endometriosis cases and the symptomatic controls (46.8 vs. 48.5, P = 0.034). Average annual economic cost of endometriosis cases was Int$9864 (95% CI: $8811-$10 917) including healthcare, costs relating to absence and loss of productivity at work.

CONCLUSION

Prevalence was lower than the global 10% estimate, and substantial proportion of women without endometriosis reported moderate/severe pelvic pain hinting at many undiagnosed cases within this population. Coupled with lower quality of life, significant economic burden and underutilized pain management options, the study highlights multiple opportunities to improve care for endometriosis patients and women with pelvic pain.

Effects of Supplementation with Microalgae Extract from Phaeodactylum tricornutum (Mi136) to Support Benefits from a Weight Management Intervention in Overweight Women

BACKGROUND

Microalgae like Phaeodactylum tricornutum (PT) contain the carotenoid, fucoxanthin, which has been purported to promote fat loss, lower blood lipids, and improve glucose management. This study examined whether dietary supplementation with microalgae extracts from PT containing 4.4 mg/d of fucoxanthin affects changes in body composition or health markers in overweight women during an exercise and diet intervention.

MATERIALS AND METHODS

A total of 37 females (28.6 ± 7.9 years, 80.2 ± 14.9 kg, 29.6 ± 3.8 kg/m², 41.4 ± 4.2% fat) fasted for 12 h, donated a fasting blood sample, completed health and mood state inventories, and undertook body composition, health, and exercise assessments. In a counterbalanced, randomized, and double-blind manner, participants ingested a placebo (PL), or microalgae extract of Phaeodactylum tricornutum standardized to 4.4 mg of fucoxanthin (FX) for 12 weeks while participating in a supervised exercise program that included resistance-training and walking (3 days/week) with encouragement to accumulate 10,000 steps/day on remaining days of the week. The diet intervention involved reducing energy intake by about -300 kcal/d (i.e., ≈1400-1600 kcals/d, 55% carbohydrate, 30% fat, 15% protein) to promote a -500 kcal/d energy deficit with exercise. Follow-up testing was performed at 6 and 12 weeks. A general linear model (GLM) with repeated measures statistical analysis was used to analyze group responses and changes from baseline with 95% confidence intervals.

RESULTS

Dietary supplementation with microalgae extract from PT containing fucoxanthin for 12 weeks did not promote additional weight loss or fat loss in overweight but otherwise healthy females initiating an exercise and diet intervention designed to promote modest weight loss. However, fucoxanthin supplementation preserved bone mass, increased bone density, and saw greater improvements in walking steps/day, resting heart rate, aerobic capacity, blood lipid profiles, adherence to diet goals, functional activity tolerance, and measures of quality of life. Consequently, there appears to be some benefit to supplementing microalgae extract from PT containing fucoxanthin during a diet and exercise program. Registered clinical trial #NCT04761406.

The effect of mirror therapy in patients with frozen shoulder

Introduction

This study was designed to compare mirror therapy and visual feedback with the control group in adhesive capsulitis patients.

Methods

Thirty-six patients, divided into three groups as mirror therapy, visual feedback and control for 15 sessions of treatment. Evaluations were made before treatment, at 6th and 10th weeks. Bilateral glenohumeral exercise was performed at the end of each session with the affected extremity behind the mirror in the mirror group, with both upper extremities in front of the mirror in the visual feedback group, and without the mirror in the control group.

Results

There were statistically significant differences between the mirror therapy and visual feedback in terms of pain severity change, and the visual feedback was superior to the change in pain severity compared to the control. Visual feedback showed significant improvement in mean change from baseline to week 10 in shoulder pain and disability index scores compared to control (p = 0.012). There was no significant difference between the groups in terms of modified constant score, proprioception and shoulder range of motion.

Conclusion

It was determined that the exercises performed by seeing the affected extremity in the mirror were more effective than mirror therapy and control group.

The Preference-Based Multiple Sclerosis Index: an assessment of its psychometric properties and translation into Turkish

PURPOSE

To translate Preference-Based Multiple Sclerosis Index (PBMSI) into Turkish, investigate its psychometric properties and differences between its two scoring algorithms: PBMSI-Rating Scale (PBMSI-RS) and PBMSI-Standard Gamble (PBMSI-SG).

METHODS

An expert committee supervised the translation process. Psychometric properties were evaluated in 104 people with multiple sclerosis. Exploratory common factor analysis was used to investigate structural validity. Convergent validity was assessed by formulating hypotheses about correlations between PBMSI and other HRQL measures, disability level, walking-related measures, and MS symptoms. Known-groups validity was assessed against different measures of disability and walking capacity. Test-retest reliability was assessed by calculating the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC95%).

RESULTS

Factor analysis revealed one factor (Eigenvalue = 2.46). PBMSI-RS and PBMSI-SG correlated significantly with other measures (p < .001). Both could differentiate between individuals with different levels of disability and walking capacity (p < .05, d  ≥  0.50). Relative test-retest reliability was moderate for PBMSI-RS (ICC = 0.75) and good for PBMSI-SG (ICC = 0.83). SEM and MDC95% values were 0.16 and 0.44 for PBMSI-RS and 0.10 and 0.28 for PBMSI-SG, respectively.

CONCLUSION

Turkish version of PBMSI has good psychometric properties to assess health-related quality of life in people with multiple sclerosis. PBMSI-SG should be preferred over PBMSI-RS.IMPLICATIONS FOR REHABILITATIONHealth-related quality of life is often used as a primary or secondary endpoint in multiple sclerosis research.The Preference-Based Multiple Sclerosis Index is the first preference-based health-related quality of life measure developed in multiple sclerosis using patient preferences.Preference-Based Multiple Sclerosis Index was translated to Turkish and demonstrated good psychometric properties, including structural, convergent, known-groups validity, internal consistency, and test-retest reliability.Professionals working in the field of multiple sclerosis research and rehabilitation may benefit from using the Preference-Based Multiple Sclerosis Index as it is a short and psychometrically robust instrument.

The effect of postoperative sling immobilization and early mobilization on clinical and functional outcomes after arthroscopic rotator cuff repair: A propensity score-matched analysis

BACKROUND

Optimal postoperative management is controversial after arthroscopic rotator cuff repair (ARCR).

OBJECTIVE

The aim of the study was to evaluate outcomes of patients with and without postoperative sling immobilization after undergoing arthroscopic RCR rotator cuff repair.

METHOD

369 arthroscopic full thickness superior rotator cuff tears (RCT) with a minimum follow-up of 6 months were included in this study. Propensity score matching was performed for age, sex, BMI, and tear size. Pain (VAS score), shoulder range of motion (ROM), functional outcome (ASES, Constant-Murley [CM] and Oxford shoulder score [OSS]), and health related quality of life (SF-36) scores were compared between patients with and without sling immobilization.

RESULTS

According to the propensity match score, 92 patients (50 sling immobilization and 42 no sling immobilization) were matched to be almost identical in age (62.5 ± 8.0 vs. 61.8 ± 5.9), sex (female 78% vs. 76.2%), BMI (28.1 ± 2.8 vs. 27.8 ± 2.6), and tear size (2.7 ± 1.1 vs. 2.9 ± 0.8). The postoperative physical functioning domain of SF-36 scores was found to be significantly higher in the no sling group (p= 0.034).

CONCLUSION

Early mobilization after arthroscopic small and medium sized full thickness superior rotator cuff repair is associated with improved ROM and quality of life scores.

Reliability and validity of Turkish versions of Sciatica Bothersomeness and Sciatica Frequency Index

BACKGROUND

The Sciatica Frequency Index (SFI) and Sciatica Bothersomeness Index (SBI) are two separate indices scored for both the bothersomeness and frequency of radiating symptoms. There is no Turkish scale used specifically for sciatica.

OBJECTIVE

We aimed to translate SBI and SBI in Turkish and investigate the reliability and validity of these indices.

METHODS

A total of 80 patients with lumbar disc herniation (LDH) were prospectively included. Construct validity was assessed by comparing the SBI and SFI with subscales of Short Form 36 (SF-36), back and leg Numeric Rating Scale (NRS) and Roland Morris Disability Questionnaire (RMDQ). Reliability was assessed by internal consistency (Cronbach's alpha) and test-retest reliability.

RESULTS

A weak correlation was found between SBI/SFI, back NRS and SF-36 subgroups while a moderate correlation was found between SBI/SFI, RMDQ and leg NRS. The SBI and SFI had high internal consistency measured by Cronbach's alpha (0.76 and 0.73). Test-retest reliability of the SBI and SFI were 0.95 (95% CI: 0.92-0.97) and 0.95 (95% CI: 0.92-0.97) respectively, indicating excellent reliability.

CONCLUSION

The Turkish versions of the SFI/SBI are a valid and reliable tool supporting their usability in patients with LDH-induced sciatica.

Which high-intensity interval training program is more effective in patients with coronary artery disease?

The aim of the study is to examine high-intensity interval training (HIIT) programs and a moderate-intensity continuous training (MICT) program, which are frequently used in cardiac rehabilitation programs in terms of their effects on the functional capacity and quality of life of patients with coronary artery disease (CAD). The study included 20 patients with CAD (mean age, 60.95 ± 5.08 years) who had undergone revascularization surgery. The participants were randomized into HIIT-short, HIIT-long, and MICT groups. All the groups participated in a 24-session exercise-based cardiac rehabilitation program. The participants' exercise capacity was evaluated using the maximal exercise test and estimated VO2max values, functional capacity using the 6-min walk test (6MWT), and quality of life using the Short Form-36 survey and MacNew Heart Disease Health-related Quality of Life (MacNew) questionnaire. It was determined that the estimated VO2max values statistically significantly improved after treatment (P < 0.05), and both HIIT groups were superior to the MICT group (P < 0.05). Only the HIIT groups achieved the minimal clinically important difference in the 6MWT distance. After treatment, only the MICT group had a statistically significant improvement in quality of life. There was no statistically significant difference between the groups in relation to the improvement in the 6MWT distance and quality of life (P > 0.05). The results of our study showed that both HIIT programs were superior to MICT in improving the maximal exercise capacity of patients with CAD, and the three programs had a similar effect on quality of life.

DESIGN AND METHODS

This cross-sectional study included 60 patients who completed the Beck Anxiety Inventory, the Beck Depression Inventory, and the 36-Item Short-Form Health Survey.

FINDINGS

Anxiety, depression, and mental health showed significant differences in different time measurements, and combined effects of surgical technique and time factor.

PRACTICE IMPLICATIONS

Preoperative routine evaluations can speed up recovery, reduce cost, and improve quality of life by preventing the possible negative effects of anxiety and depression.

The Cyprus Women’s Health Research (COHERE) initiative: normative data from the SF-36v2 questionnaire for reproductive aged women from the Eastern Mediterranean

Purpose

Describe the health-related quality of life for a representative cohort of women aged 18–55 in Northern Cyprus.

Methods

We utilised the SF-36-Health-Survey-version-2 (SF-36v2) questionnaire as part of the COHERE Initiative study to calculate the eight physical and mental subscale scores, as well as the two overall summary measures for physical and mental health, where we present results using Cyprus-specific scoring as well as scores based on the test developers’ algorithms. We examined associations between sociodemographic characteristics for both scores.

Results

A total of 7089 women fully completed the SF-36v2 questionnaire (mean age = 36.9), which was reliable and valid in this population. We observed better physical health in ages 18–25 compared to 46–55 (53.32 vs. 46.72 (p < 0.001)) and better mental health in women aged 46–55 compared to 18–25 (52.07 vs. 47.95 (p < 0.001)). Women in employment had better physical and mental health compared to those who were unemployed (physical: 50.25 vs 49.95, p < 0.001 and mental: 50.25 vs 49.24, p = 0.083) and scores increased as educational attainment increased (physical: 47.55 for primary to 51.58 for postgraduate, mental: 48.88 to 50.59, p < 0.001). Turkish Cypriot women had higher scores than Turkish women (physical: 50.42 vs 49.30, mental: 50.43 vs 49.10, p < 0.001).

Conclusion

These are the first population normative values published from a large representative sample of women between 18 and 55 years from the Eastern Mediterranean region. We found better physical health in younger women and better mental health in older women. Turkish Cypriot women and non-migrant women had better mental health, and HRQOL was highest in those in paid employment and those with a higher educational achievement.

Isokinetic Evaluation of Knee Strength and Endurance in Hemodialysis Patients Treated with the Transpatellar Tunnel Technique for Bilateral Spontaneous Quadriceps Tendon Ruptures

There are numerous surgical techniques described for treating acute quadriceps tendon rupture. We aim to evaluate the strength of the quadriceps tendon using isokinetic tests in hemodialysis patients treated with the transpatellar tunnel technique for bilateral spontaneous quadriceps tendon ruptures. Additionally, functional and clinical results were investigated and compared with hemodialysis patients without a history of quadriceps tendon rupture. We retrospectively reviewed hemodialysis patients diagnosed with quadriceps tendon rupture who were operated between 2005 and 2015 at our institution. Eight patients with simultaneous bilateral quadriceps tendon rupture treated with the transpatellar tunnel technique (group 1; the operated group) and 10 patients with chronic renal failure without a history of quadriceps tendon rupture who underwent hemodialysis (group 2; the control group) were included in this study. The active range of motion (ROM), Lysholm and Tegner scores, knee flexor and extensor muscle strengths, and endurances were measured using an isokinetic dynamometer for each group and compared between the groups. The mean age was 44.6 and 40.2 years in groups 1 and 2, respectively. The mean follow-up was 58.6 (range, 24-140) months in group 1. The active ROM was 113.7 ± 9.7 degrees in group 1 and 130 ± 4.8 degrees in group 2 (p < 0.001). The mean Tegner score was not significantly different between the groups (1.87 ± 1.1 in group 1 vs. 2.6 ± 0.9 in group 2; p = 0.212). However, the Lysholm score was significantly higher in group 2 (93.2 ± 7.3 vs. 76.7 ± 13.8; p = 0.009). The mean extensor strength and endurance were significantly higher in group 2 than in group 1. The mean flexor strength and endurance were higher in group 1 than in group 2, but no significant difference was found. Although using the transpatellar tunnel technique for bilateral spontaneous quadriceps tendon ruptures in hemodialysis patients can provide acceptable functional results, the ROM and strength particularly in extensor muscle might be significantly lower than control group. Level of evidence is Level III therapeutic case-control study.

Translation, cross-cultural adaptation, reliability, and validity of Turkish version of the university of California Los Angeles (UCLA) shoulder scale into Turkish

PURPOSE

To translate and culturally adapt the University of California Los Angeles (UCLA) shoulder scale into Turkish (T-UCLA) and determine its psychometric properties.

MATERIAL AND METHODS

The UCLA scale was translated into Turkish using Beaton guidelines. Ninety-one patients (46 male; mean age: 46.0 ± 13.7 years) with shoulder disorders completed T-UCLA and American Shoulder and Elbow Score (ASES), Simple Shoulder Test (SST) and 36-Item Short Form (SF-36). Test-retest reliability was tested in 50 patients at a mean of 5.2 ± 2.2 days after initial assessment. Validity was evaluated in 91 patients, and correlations between ASES, SST and SF-36 were analyzed. Responsiveness was assessed in 33 patients who underwent arthroscopic rotator cuff repair with a mean follow-up of 12.8 ± 0.5 months.

RESULTS

Test-retest reliability of overall T-UCLA, pain and function subscales were 0.96, 0.94 and 0.86, respectively. The correlation coefficients between T-UCLA and SST and ASES were r = 0.752 and r = 0.783, respectively (p < 0.001). The highest correlations between T-UCLA and SF-36 were observed in physical functioning (r = 0.64) and bodily pain subscales (r = 0.66). No ceiling or floor effect observed. Overall and subscales of T-UCLA were highly responsive (ES = 3.22-4.31).

CONCLUSION

T-UCLA has sufficient reliability and validity similar to original and translated versions. T-UCLA is responsive in patients who underwent rotator cuff repair.Implications for rehabilitationIn this study, Turkish version of the UCLA was found to be a reliable and valid outcome measure in patients with various shoulder pathologies.Turkish version of the UCLA is a very responsive tool in patients with who underwent arthroscopic repair of rotator cuff tears.

Mental and physical health-related quality of life and food addiction after obesity surgery: The first 2-year outputs

PURPOSE

The aim of the study was to investigate mental and physical health-related quality of life and food addiction of patients who underwent obesity surgery.

DESIGN AND METHODS

A cross-sectional and descriptive design study was included 80 adult patients who completed the Yale Food Addiction Scale and the 36-Item Short-Form Health Survey.

FINDINGS

It was found that mental and physical health mean scores of the patients were 61.48 and 72.43, respectively. None of the patients were food-addicted.

PRACTICE IMPLICATIONS

Patients were moderate level in the mental and physical health and were no food addiction in the first 2 years. It is thought that mental health support and follow-up following postoperative should be routinely.

The Combination of Exercise and Manual Therapy Versus Exercise Alone in Total Knee Arthroplasty Rehabilitation: A Randomized Controlled Clinical Trial

BACKGROUND

Total knee arthroplasty (TKA) is one of the most commonly performed orthopedic surgeries in the lower extremity. However, patient dissatisfaction and functional disability are mostly experienced because of pain and limited range of motion (ROM). Although manual therapy is commonly implemented to improve ROM and modulate pain in the management of musculoskeletal disorders, there is a lack of evidence about its clinical effectiveness on postoperative TKA rehabilitation.

OBJECTIVE

To investigate the effectiveness of an exercise program combined with manual therapy compared with an exercise program only for pain, ROM, function, quality of life, and patient satisfaction outcomes.

DESIGN

A randomized controlled clinical trial.

SETTING

Rehabilitation unit of a university hospital.

PARTICIPANTS

Forty-two patients (68.45 ± 6.3 years) scheduled for unilateral TKA as a treatment of severe osteoarthritis.

INTERVENTIONS

Joint and soft tissue mobilizations in addition to exercise therapy were provided to the mobilization group (n = 21) while the control group received exercise therapy only (n = 21).

MAIN OUTCOME MEASURES

The outcome measures were numeric pain-rating scale, knee ROMs, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, 10-meter walk test (10MWT), 5-times sit to stand test (5SST), and Short Form-12 (SF-12).

RESULTS

Improvements in pain outcomes were significantly higher in the mobilization group than in the control group (P = .001, F [3, 33] = 7.06) and the between-group difference in change score was 1.3 points (P = .001). Although the between-group difference in change score was 12.8° for knee flexion at 2 months (P = .001), the overall group-by-time interactions were not significant for flexion and extension ROMs (P = .175, F [3, 33] = 1.75 and P = .57, F [2, 34] = 0.56, respectively). Additionally, there were statistically meaningful group-by-time interactions on total WOMAC score (P = .006, F [2, 34] = 5.29), 10MWT (P = .002, F [3, 33] = 5.98), and SF-12 mental component summary (P = .01, F [2, 34] = 4.92) favoring the mobilization group. Also, patient satisfaction was higher in the mobilization group (P = .02).

CONCLUSIONS

A structured exercise program combined with manual therapy can be more beneficial in improving pain, function, and patient satisfaction compared to exercise program alone for postoperative TKA patients.

Cross-cultural adaptation and translation of the Constant Murley Score into Arabic

Introduction: Shoulder pain is a major disorder of the musculoskeletal system. To the best of our knowledge, there is no documentation of an Arabic version of the shoulder disability and pain measurements. Constant Murley Score (CMS) is one of the standard questionnaires for clinical practice and research. The aim of this research centred around the evaluation of the Arabic Constant Murley Score and subsequently assessing the reliability and validity in comparison to disabilities of the arm, shoulder, and hand (DASH). Methods: Hundred and twenty five patients took part in this research. We did the internal consistency tests with Cronbach’s alpha. Intra-correlation coefficient, convergent validity, convergent construct validity, responsiveness, and floor and ceiling effects were also calculated. Results: Principal component analysis showed that the variance was 63.31% with a factor range of 0.42–0.85, which fulfils the uni-dimensionality criterion. Also, the Arabic CMS correlated negatively with the DASH score (−0.82, p < 0.001). The Arabic version of CMS was consistent with Cronbach’s alpha of 0.74. With Inter Class Correlation Coefficient (ICC) = 0.83 it also showed a very good test-retest reliability. Conclusion: Ours is the first translation and cross-cultural adaptation of the CMS into Arabic. Important evidences of validity were tested such as uni-dimensionality, convergent validity, and internal consistency. Results demonstrate an acceptable Cronbach’s alpha of 0.74, ICC = 0.830 indicating excellent reliability and a strong correlation of the Arabic CMS with the DASH score (r = −0.820). Overall, the Arabic version of CMS is a good and reliable diagnostic tool for patients experiencing shoulder pain.

Effects of microprocessor-controlled prosthetic knees on self-reported mobility, quality of life, and psychological states in patients with transfemoral amputations

OBJECTIVE

This study aimed to determine the effects of the microprocessor-controlled prosthetic knee (MPK) joint on self-mobility, body perceptions, depression, and quality of life in patients with unilateral transfemoral amputations (TFAs).

METHODS

Thirty consecutive patients (28 males, mean age=38.5 years, age range=22-57) who had previously used non-MPKs and who were approved to use swing and stance phase-control MPKs were included in this 12-week clinical study. Before the MPK use and after the three-month follow-up, prosthetic use and locomotor capabilities were evaluated using the Houghton Scale and the Locomotor Capabilities Index (LCI-5), respectively. Body perception was assessed using the Amputee Body Image Scale (ABIS). The depressive symptoms and quality of life were evaluated using the Beck Depression Inventory (BDI) score and the 36-Item Short- Form Health Survey (SF-36), respectively.

RESULTS

After MPK use, statistically significant ameliorations were observed in all outcome measures. The basic and advanced LCI-5 increased from 26.7±2.2 and 24.8±5.2 to 27.6±1.2 (p=0.007) and 27±2.1 (p=0.004), respectively. Houghton scores improved from 9±1 to 10.3±0.8 (p=0.000). The ABIS and BDI scores decreased from 43.2±10.9 and 5.7±6.6 to 37.1±8.9 (p=0.000) and 3.8±4.5 (p=0.015), respectively. Also, the SF-36 physical function and vitality subscales increased from 71.2±24.0 and 75.5±14.6 to 85.6±16.6 (p=0.001) and 81.7±14.1 (p=0.015), respectively.

CONCLUSION

MPK use provides significant improvements in the locomotor capabilities, quality of life, and activities of daily living to patients with TFAs as well as improves their body image perceptions and depressive symptoms.

Correlations between radiographic spinopelvic parameters and health-related quality of life: A prospective evaluation of 37 patients with facioscapulohumeral muscular dystrophy

OBJECTIVE

The purpose of this study was to evaluate the relationship between spinopelvic parameters and health-related quality of life.

METHODS

Patients with Facioscapulohumeral muscular dystrophy (FSHD) were asked to volunteer to participate in this study from April 2018 to December 2019. Patient data, including age, sex, body mass index (BMI), and duration of the diagnosis of FSHD were obtained. Short Form (SF-36) questionnaire was completed for all patients. All patients underwent lateral radiography of the whole spine. The radiographic parameters examined were pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), cervical lordosis (CL), T1 spinopelvic inclination (T1 SPI), thoracic kyphosis (TK), Pelvic incidence- lumbar lordosis (PI-LL) and sagittal vertical axis (SVA).

RESULTS

Thirty-seven patients (16 females and 21 males) were included in the study, with a mean age of 39.1 years. The mean duration of diagnosis was 13.5 ± 11.4 years and mean BMI was 24.2 kg/m2. Physical composite score (PCS) was 38.7 and mental composite score (MCS) 60.8 detected. Radiographic analyses included the following: the mean PT was 9.1°, PI 52.1°, SS 43.5°, LL 67.9°, CL 9.8°, T1 SPI -2.5°, TK 23.1°, SVA 37.6 mm. PI-LL was -13.1°. We identified 31 patients with match (left) PI-LL and six patients with mismatch (right) PI-LL.

CONCLUSION

Hyperlordosis inlumbar spine, hypolordosis in cervical spine and negative sagittal balance were the most common spinal misalignments in patients with FSHD. These patients have lower composite PCS than composite MCS. There was a significantly negative correlation between LL, PI-LL and PCS.

Reliability and validity of culturally adapted Turkish Short Musculoskeletal Function Assessment questionnaire (SMFA-TR)

AIM

This study aimed to culturally adapt and validate the Turkish version of the Short Musculoskeletal Function Assessment Questionnaire (SMFA-TR) which primarily assesses the functional status of patients.

METHODS

The translation and cross-cultural adaptation of SMFA to Turkish was made by the standardized procedure and tested for clinimetric quality. The following analyses were made to evaluate clinimetric quality of the SMFA-TR: reliability with factor analysis and Chronbach's α (construct validity), correlations between SMFA-TR and Short Form (SF)-36 (concurrent validity), test-retest reliability (intraclass correlation analyses), floor and ceiling effects. The questionnaire was applied to 166 patients with musculoskeletal problems. All patients filled in the SMFA-TR and the validated Turkish SF-36 questionnaire. Forty-two patients returned to complete the same questionnaires at 10 days.

RESULTS

Factor analysis revealed a 4-factor structure of the SMFA-TR. Cronbach's α values were over 0.88 for both original subscales (dysfunction and bother) of the SMFA. Internal consistency (0.88-0.94) and test-retest reliability coefficients (0.90-0.98) were high for both subscales. Turkish SF-36 questionnaire conventional subscales showed significant correlations with SMFA-TR subscales. No floor or ceiling effects were found.

CONCLUSION

The Turkish version of the SMFA was found to be reliable and valid for Turkish-speaking patients with musculoskeletal injuries or disorders.

Effects of Modified Posterior Shoulder Stretching Exercises on Shoulder Mobility, Pain, and Dysfunction in Patients With Subacromial Impingement Syndrome

BACKGROUND

Posterior shoulder stretching exercises (PSSEs) aim to reduce posterior shoulder tightness (PST). Position modification of traditional PSSEs has been suggested to minimize inadequate control of scapular and glenohumeral rotation, possibly leading to increased subacromial impingement.

HYPOTHESIS

Modified PSSEs will have positive effects on shoulder mobility, pain, and dysfunction.

STUDY DESIGN

Randomized controlled trial.

LEVEL OF EVIDENCE

Level 1.

METHODS

A total of 67 symptomatic patients with subacromial impingement syndrome (SIS) and shoulder internal rotation asymmetry were randomly assigned to 3 groups: modified cross-body stretch (MCS) (n = 22; treatment program + MCS), modified sleeper stretch (MSS) (n = 22; treatment program + MSS), and a control group (n = 23; treatment program consisting of only modalities, range of motion [ROM], and strength training but no PSSEs) for 4 weeks. Pain, PST, shoulder rotation ROM, and dysfunction were evaluated.

RESULTS

Pain, PST, shoulder rotation ROM, function, and disability improved in all groups (P < 0.05). The MCS and MSS groups had better results compared with the control group with regard to pain with activity, internal rotation ROM, function, and disability (P < 0.05). There was no significant difference between the stretching groups (P > 0.05).

CONCLUSION

All treatments improved pain, shoulder mobility, function, and disability in patients with SIS. However, modified PSSEs in addition to a treatment program was superior to the treatment program alone (without PSSEs) in improving pain with activity, internal rotation ROM, and dysfunction. Moreover, stretching provided clinically significant improvements.

CLINICAL RELEVANCE

Modified PSSEs, in addition to a treatment program, are beneficial for patients with SIS. Both modified cross-body and sleeper stretches are safe and efficacious for improving shoulder mobility, pain, and dysfunction.

Effect of a pedometer-based walking challenge on increasing physical activity levels amongst hospital workers

Background

More than 50% of Qatari adults are physically inactive. The workplace is an excellent environment to implement cost-effective, efficient behavioural physical activity (PA) interventions to increase PA. This study evaluated whether a pedometer-based walking challenge would increase PA levels amongst hospital workers.

Methods

A pedometer-based workplace walking intervention was implemented in April–August 2017. Amongst 800 recruited full-time hospital workers, a cross-sectional sample of 212 workers completed the online questionnaires Quality of Life Questionnaire, International Physical Activity Questionnaire (IPAQ), and Workforce Sitting Questionnaire. A sub-sample of participants (n = 54) wore a pedometer for 3 months. They recorded their daily step count through an online web platform linked to the pedometer. Another cross-sectional sample (n = 194) in the same target population completed online questionnaires at post intervention.

Results

The IPAQ assessed physical activity at post-intervention was higher compared to pre-intervention. In a sub-sample (n = 54) that provided pedometer data, workers’ step count during intervention was significantly higher (9270) from pre-intervention (7890) (p = 0.048).

Conclusions

Although self-reported PA was higher post-intervention, the subsample showed objectively assessed physical activity did not exceed the threshold recommended for optimal health. Therefore, encouraging participation and maintaining motivation amongst workers in a work-based PA programme is challenging.

Effects of physical therapy agents on pain, disability, quality of life, and lumbar paravertebral muscle stiffness via elastography in patients with chronic low back pain

Objectives

This study aims to evaluate early effects of combined hot pack (HP) and transcutaneous electrical nerve stimulation (TENS) treatment and therapeutic ultrasound (US) on pain, quality of life, disability, and the multifidus muscle stiffness.

Patients and methods

Between December 2016 and March 2017, a total of 69 patients (36 females, 33 males; mean age 48.9±10.9; range, 27 to 73 years) were included in this randomized-controlled study. The patients were divided into three groups as HT + TENS (Group H+T, n=23), HP + TENS + US (Group H+T+U, n=23), and controls (control group, n=23). All patients filled out the Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), and Short Form-36 (SF-36) questionnaire at baseline and at the end of treatment. The left multifidus muscle strain ratio at fourth lumbar spinal level was obtained from the upper, middle, and lower parts of the muscle along the longitudinal axis on the first and last days of treatment.

Results

There was a significant improvement in the NRS, ODI, and SF-36 physical function, physical role function, pain, and general health perceptions in the H+T and H+T+U groups, compared to the control group (p<0.05). However, there was no significant difference between the H+T and H+T+U groups. The H+T+U group showed an improvement in the SF-36 social role function and emotional role function. There was no significant difference in the multifidus muscle strain ratios among the groups.

Conclusion

Our study results suggest that H+T treatment has a beneficial effect on pain, disability, and certain subscales of the quality of life. However, US seems not to have an additional benefit.

Reliability and Validity of the Turkish Version of Foot and Ankle Ability Measure for Patients With Chronic Ankle Disability

The Foot and Ankle Ability Measure is a valid, reliable, and widely used self-reported questionnaire for the foot. It has been adapted and validated for a Turkish-speaking population. The purpose of this study was to provide evidence for validity and reliability of the Turkish version of the Foot and Ankle Measure (FAAM-T) in patients with chronic ankle instability (CAI). A total of 316 patients with CAI were enrolled. The internal consistency and test-retest reliability were evaluated. Validity was examined using correlations with the Short Form Health Survey version 2.0 (SF-36v2) questionnaire. Cronbach's alpha scores were 0.94 and 0.96 for the the FAAM-T ADL (Activities of Daily Living) and FAAM-T Sports subscales, respectively, indicating high internal consistency. For the second administration, Cronbach's alpha was found to be 0.96 for both subscales of the FAAM-T. The test-retest reliability of the FAAM-T was very high for both subscales with an intraclass correlation coefficient of 0.97 and 0.94, respectively (p < .001). The standard error of the mean and minimal detectable change were determined to be 2.5 and 6.7 for the FAAM-T ADL and 6.9 and 18.5 for the FAAM-T Sport. The FAAM-T ADL and Sport subscales were strongly correlated with the SF-36v2 PF (physical functioning; r = 0.51, r = 0.40, respectively; p = .001) and SF-36v2 PCS (physical component scale; r = 0.64, r = 0.55, respectively; p = .001). The weakest associations between the FAAM-T ADL and Sport and the SF-36v2 were noted for the mental health subscale (r = 0.08 and r = 0.03) and the SF-36v2 MCS (mental component scale; r = .05 and r = .006, respectively). This study provides evidence for validity, internal consistency, and test-retest reliability for the FAAM-T to evaluate patients with CAI.

The quality of life analysis of knee prosthesis with complete microprocessor control in trans-femoral amputees

Objective

The aim of this study was to analyze the patient demographics, etiology of limb loss as well as reporting SF-36 scores for microprocessor prosthesis users in Turkish population.

Methods

We reviewed 72 patients (61 male and 11 female; mean age: 37.7 ± 10.7) with uni-lateral, above knee amputation and a history of regular and microprocessor prosthesis use. All patients were called back for a last follow-up and they were asked to fill a self-administered general health status questionnaire (SF-36).

Results

According to the SF-36 results; physical component score (PCS) score was 46 ± 7.3 and mental components summary (MCS) score was 46.5 ± 9.1. These scores have statistical similarity with Turkish healthy controls, except SF (social functioning) sub-dimension. PCS score for women microprocessor users were significantly lower than men (43.3 vs. 48.7, p = 0.03), but MCS scores were similar in between genders (46 vs. 48.2, p = 0.13). Conventional prostheses usage time was positively correlated with physical function (PF) scores (r = 0.322, p = 0.010). Microprocessor prosthesis usage time was negatively correlated with role limitations due to emotional problem (RE) scores (r = −0,313, p = 0.009).

Conclusion

The quality of life surveys were showed that the loss of an extremity have higher physical and psychological impact on women's physical scores. Overall, SF-36 results were similar in microprocessor using amputee's and Turkish normal controls.
