Sex and body mass index correlate with Western Ontario and McMaster Universities Osteoarthritis Index and quality of life scores in knee osteoarthritis

Elbaz A, Debbi EM, Segal G, Haim A, Halperin N, Agar G, Mor A, Debi R. Sex and body mass index correlate with Western Ontario and McMaster Universities Osteoarthritis Index and quality of life scores in knee osteoarthritis.

Objective

To examine the associations of sex, body mass index (BMI), and age with knee osteoarthritis (OA) symptomatic severity.

Design

A cross-sectional retrospective analysis.

Setting

Patients completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Data were acquired from a stored database of a private therapy center.

Participants

Patients (N=1487) with symptomatic knee OA were evaluated.

Interventions

Not applicable.

Main Outcome Measures

WOMAC questionnaire and SF-36.

Results

BMI correlated significantly with worse knee OA symptoms for all WOMAC and SF-36 subcategories (all P≤.001). Age correlated significantly with worse symptoms only for WOMAC function and SF-36 physical functioning (P=.001 and P=.009, respectively). A significant difference across BMI quintiles was found for all WOMAC and SF-36 subcategories (all P≤.01). Women showed worse knee OA symptoms in all WOMAC and SF-36 subcategories (all P≤.001). There was a significant interaction of sex by BMI in WOMAC pain and WOMAC function (P=.01 and P=.02, respectively).

Conclusions

Based on the results of this analysis, it can be concluded that women and patients with a higher BMI with knee OA are at a greater risk for worse symptoms.     

Cross-cultural adaptation,reliability, and validity of the Japanese version of the Cumberland ankle instability tool

Purpose To study validity and reliability of a Japanese version of the Cumberland Ankle Instability Tool and to determine the optimal cutoff score. Methods In this study, the questionnaire was cross-culturally adapted into Japanese. The psychometric properties tested in the Japanese version of the CAIT were measured for criteria validity, internal consistency and test–retest reliability in 111 collegiate soccer athletes. We also established the questionnaire cutoff score for discriminating between individuals with and without CAI. Results There was a significant correlation between the Japanese version of the CAIT and the Karlsson score (r?=?0.604, p?α?=?0.833) and reliability [intraclass correlation coefficient (ICC)?=?0.826, 95% confidence interval (CI): 0.732–0.888]. The optimal cutoff score was?≤25, which was consistent with previous reports. Conclusions The Japanese version of the CAIT has been shown to be a valid and reliable questionnaire for determining the presence of CAI. We expect that researchers and clinicians will use the Japanese version of the CAIT in Japan.

• Implications for Rehabilitation

• Chronic Ankle Instability (CAI), which not only increases recurrence rate of ankle sprain but also decreases athletic performance, is a residual symptom after ankle sprain.

• Cumberland Ankle Instability Tool, which has the reliability and validity to assess CAI, will be critically useful in assessment procedure for CAI.

• It is preferable for clinicians and researchers to use the native language version of the CAIT.

     

Cross-cultural adaptation,reliability and validity of the Turkish version of the Lower Limb Functional Index

Abstract

Purpose: This study aims to adapt culturally a Turkish version of the Lower Limb Functional Index (LLFI) and to determine its validity, reliability, internal consistency, measurement sensitivity and factor structure in lower limb problems. Method: The LLFI was translated into Turkish and cross-culturally adapted with a double forward–backward protocol that determined face and content validity. Individuals (n?=?120) with lower limb musculoskeletal disorders completed the LLFI and Short Form-36 questionnaires and the Timed Up and Go physical test. The psychometric properties were evaluated for the all participants from patient-reported outcome measures made at baseline and repeated at day 3 to determine criterion between scores (Pearson’s r), internal consistency (Cronbachs α) and test–retest reliability (intraclass correlation coefficient – ICC_2.1). Error was determined using standard error of the measurement (SEM) and minimal detectable change at the 90% level (MDC₉₀), while factor structure was determined using exploratory factor analysis with maximum likelihood extraction and Varimax rotation. Results: The psychometric characteristics showed strong criterion validity (r?=?0.74–0.76), high internal consistency (α?=?0.82) and high test–retest reability (ICC_2.1?=?0.97). The SEM of 3.2% gave an MDC₉₀?=?5.8%. The factor structure was uni-dimensional. Conclusions: Turkish version of LLFI was found to be valid and reliable for the measurement of lower limb function in a Turkish population.

• Implications for Rehabilitation

• Lower extremity musculoskeletal disorders are common and greatly impact activities among the affected individuals pertaining to daily living, work, leisure and quality of life.

• Patient-reported outcome (PRO) measures have advantages as they are practical, cost-effective and clinically convenient for use in patient-centered care.

• The Lower Limb Functional Index is a recently validated PRO measure shown to have strong clinimetric properties.

     

Cross-cultural adaptation,reliability and validity of the Persian version of the modified falls efficacy scale

Purpose.?To translate the Swedish version of the Falls Efficacy Scale (FES), the FES(S), into Persian, and to determine reliability and validity of the scale to be used for Persian speaking elderly people.

Method.?The ‘forward-backward’ procedure was applied to translate the FES(S) into Persian. A methodological study was then carried out to determine the psychometric properties of the Persian version of the scale. Eighty-one community-dwelling elderly persons (≥65 years) were included.

Results.?Both reliability and validity of the Persian FES(S) were found to be acceptable (Cronbach's α == 0.75, interclass correlation coefficients == 0.99, p < 0.001 and standard errors of measurements == 1.82). Low to moderate negative correlations of the total score of the scale with the age of the participants and number of falls in the past year were shown. There were also low to moderate correlations between the Persian FES(S) score and the Mini-Mental State Examination score, duration of walks and physical fitness. The participants who took a daily walk, felt healthy, reported no general tiredness and who had had no fall during the past year rated their self-efficacy higher than did their peers.

Conclusions.?The present study verified that the Persian FES(S) is a culturally relevant, valid and reliable tool for measuring self-perceived confidence in Iranian older adults.     

Cross-cultural adaptation and validation of the Arabic version of the knee outcome survey-activities for daily living scale

Purpose: The purpose of this study is to cross-culturally adapt the Knee Outcome Survey-Activities of Daily Living Scale into Arabic and to assess its psychometric properties (internal consistency, reliability, validity, and responsiveness) in patients with knee disorders.

Methods: The cross-cultural adaptation process for the Knee Outcome Survey-Activities of Daily Living Scale into Arabic was performed consistent with the published guidelines. The psychometric properties of this Arabic version were then evaluated. Participants completed this version three times: at baseline, 2–4 days later, and 4?weeks later. Correlations between the Arabic version of Knee Outcome Survey-Activities of Daily Living Scale and the Arabic version of the Short Form-36 Health Survey, Get Up and Go, and Ascending/Descending stairs tests were evaluated.

Results: Linguistic and cultural issues were addressed. The Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale demonstrated excellent internal consistency (Cronbach’s alpha?=?0.97) and excellent test–retest reliability (intraclass correlation coefficient?=?0.97). Construct validity of the Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale with the Arabic version of Short Form-36 Health Survey subscales ranged from r?=?0.28 to 0.53, p?r?=??0.47 to ?0.60, p?Conclusions: The Arabic version of the Knee Outcome Survey-Activities of Daily Living Scale is a reliable, valid and responsive measure for assessing knee-related symptoms and functional limitations

• Implications for rehabilitation

• The Knee Outcome Survey-Activities of Daily Living Scale-Arabic is a reliable, valid and responsive measure for assessing knee-related functional limitations.

• This Arabic version can be used in clinical practice and for research purposes to assess symptoms and functional limitations in Arabic-speaking patients with knee disorders.

• This scale is responsive to track therapeutic outcome of Arabic-speaking patients with knee disorders.

     

Cross-cultural adaptation,validity and reliability of the Arabic version of the Lower Extremity Functional Scale

Purpose: The aim was to translate and cross-culturally adapt the Lower Extremity Functional Scale (LEFS) into Arabic language and to examine its measurement properties in patients with musculoskeletal disorders of the lower extremity. Methods: Standard forward and backward translation followed by expert committee review, then preliminary testing was carried out to produce the final Arabic version of LEFS (LEFS-Ar). The test–retest reliability, measurement error, internal consistency and construct validity of the LEFS-Ar were examined in patients with musculoskeletal disorders of the lower extremity (N?=?116). Results: The LEFS-Ar had excellent test–retest reliability (ICC_2,1?=?0.96). LEFS-Ar standard error of measurement was 3.5 points while the minimal detectable change MDC₉₅ was 9.8 points. LEFS-Ar showed excellent internal consistency with Cronbach’s alpha of 0.95. Parallel analysis and factor analysis showed that LEFS-Ar measures one underlying factor with all items loading heavily on this single factor. LEFS-Ar showed significant positive correlation with patient’s global assessment of function (r?=?0.59) and that patients recovering from surgery reported lower LEFS-Ar score compared to patients with no surgery further supporting the construct validity of the LEFS-Ar. Conclusion: LEFS-Ar has excellent internal consistency, test–retest reliability with relatively small measurement error and is a valid measure of activity limitation due to lower extremity musculoskeletal disorders. All these measurement properties of the LEFS-Ar suggest the clinical usefulness of this measure.

• Implications for Rehabilitation

• The Arabic Lower Extremity Functional Scale (LEFS-Ar) is a reliable and valid measure of activity limitation due to lower extremity musculoskeletal disorders with relatively small measurement error.

• LEFS-Ar can be used in daily clinical practice and for research purposes to quantify activity limitation in Arabic-speaking individuals with lower extremity musculoskeletal disorders.

Cross-cultural translation and validation of the Greek version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with total knee replacement

Abstract

Purpose: Aim of this study is to assess the psychometric properties of the developed Greek version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in total knee replacement (TKR) patients. Methods: Psychometric properties of the Greek version of KOOS were evaluated according to the Consensus-based Standards Measurements Instruments (COSMIN) checklist. Patients’ pre-operative clinical status and post-operative outcomes at two occasions (at discharge and 10–12 days post-operatively) were evaluated using the KOOS, KOS-ADL and SF-12 Health Survey. Results: A comprehensive Greek KOOS was piloted and well accepted by patients and therefore administered to 60 consecutive TKR patients (mean age 72.2?±?7.2 years, 39 women). Excellent Internal consistency, good test–retest reliability of KOOS and KOOS 5 subdomains, respectively [ICC(2-1) 0.76, 95% CI?=?0.235–0.902 and 0.89, 95% CI?=?0.843–0.927] was yielded. A priori hypotheses for construct validity were confirmed with KOOS score and subdomains for pain, symptoms and Everyday Living function (ADL) correlating moderately with KOS-ADL. Responsiveness for KOOS subdomains of Pain and Symptoms yielded moderate effect size (ES?=?0.4). Conclusion: The Greek KOOS was found to be a practical and comprehensible self-reported measure for TKR patients with acceptable psychometric properties. It is therefore, recommendable for usage in future clinical trials and clinical practice.

• Implications for Rehabilitation

• The Greek version of KOOS is an essential assessment scale to evaluate not only acute injuries but also chronic knee associated conditions in a holistic perspective.

• The Greek KOOS has been found to be a practical and comprehensible self-reported measure for TKR patients with acceptable psychometric properties, recommendable for usage in future clinical trials and clinical practice.

Measuring the population impact of knee pain and disability with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

This study has used the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) in an unsolicited postal questionnaire to investigate the impact of knee pain and disability in the general older population. The study provides WOMAC population data for those aged over 50 and demographic and psychosocial associations with severity of WOMAC scores. A pilot survey (n=240) and repeatability study (n=80) were undertaken to test completion of the WOMAC in this new setting. The main questionnaire was mailed to 8,995 men and women aged over 50 registered with three general practices in North Staffordshire, UK. Completion rates for WOMAC items were high. Substantial reliability was found for pain and physical function scales (both >0.80). Fourteen percent of the over 50 population in this study had severe knee pain, 20% had severe difficulty with at least one area of physical functioning, 12% had both. The strongest link with severe difficulty with physical functioning was chronicity (odds ratio (OR)=6.49, 95% CI 4.65, 9.04). Other independent links were age over 75 years (odds ratio (OR)=4.11, 95% confidence interval (CI) 3.03, 5.58), depression (OR=2.80, 95% CI 2.22, 3.54), bilateral knee injury (OR=2.23, 95% CI 1.63, 3.06) and body mass index>30 (OR=2.00, 95% CI 1.51, 2.64). Similar associations were found for severe pain. The findings suggest that the WOMAC is a reliable measure for use in postal surveys. It has advantages over other instruments when measuring pain and physical function difficulty related to the knee. Chronicity, older age, injury, obesity and depression were all linked with higher WOMAC scores for knee pain severity and disability among knee pain sufferers in the general older population.

Upper extremity movement reliability and validity of the Kinect version 2

Purpose: Studies have shown that marker-less motion detection systems, such as the first generation Kinect (Kinect 1), have good reliability and potential for clinical application. Studies of the second generation Kinect (Kinect 2) have shown a large range of accuracy relative to balance and joint localization; however, few studies have investigated the validity and reliability of the Kinect 2 for upper extremity motion. This investigation compared reliability and validity among the Kinect 1, Kinect 2 and a video motion capture (VMC) system for upper extremity movements.

Design: One healthy, adult male performed six upper extremity movements during two separate sessions. All movements were recorded on the Kinect 1, Kinect 2 and VMC simultaneously. Data were analyzed using MATLAB (Natick, MA), Microsoft Excel (Redmond, WA), and SPSS (Armonk, NY).

Results: Results indicated good reliability for both Kinects within a day; results between days were inconclusive for both devices due to the inability to exactly repeat the desired movements. Range of motion (ROM) magnitudes for both Kinects were different from the VMC, yet patterns of motion were very highly correlated for both devices.

Conclusion: Simple transformations of Kinect data could bring magnitudes in line with those of the VMC, allowing the Kinects to be used in a clinical setting.

• Implications for Rehabilitation

• The clinical implications of the investigation support the notion that the Kinects could be used in the clinical setting if an understanding of their limitations exists.

• Using the Kinects to make assessments with a given data collection session is acceptable. Using the Kinects to make comparisons across different days such as before or after an intervention should be approached with caution.

• The Kinect 2 provides a more cost effective option compared to the VMC. Additionally, the Kinect is more portable, requires less time to set-up, and takes up less space, thus increasing its overall usability compared to the VMC.
