Construct validity, reliability, response rate, and association with disease activity of the quick disabilities of the arm, shoulder and hand questionnaire in the assessment of rheumatoid arthritis

Modified Chinese disabilities of arm, shoulder and hand tool: Validity and reliability for upper extremity injuries

DESIGN

Clinimetric evaluation study.

INTRODUCTION

The Chinese Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire has necessitated the development of a revised version to the specific needs of individuals with upper extremity injuries with the progress of times and lifestyle changes.

PURPOSE OF THE STUDY

This research aimed to evaluate the reliability and validity of Modified Chinese Disability of Arm, Shoulder and Hand (MC-DASH) questionnaire in individuals with upper extremity injuries.

METHODS

One hundred and one individuals with upper extremity injuries (UEI) were recruited. The function of upper extremity was measured using the electronic version of MC-DASH, and compared against the Chinese Disability of Arm, Shoulder and Hand. The MC-DASH was reassessed within three days in all individuals. We investigated the internal consistency, test-retest reliability, content validity, criterion validity, and construct validity of MC-DASH.

RESULTS

The internal consistency was deemed sufficient, as indicated by a Cronbach's alpha of 0.986 and an intraclass correlation coefficient of 0.957. Moreover, the mean total scores of MC-DASH on the first-test and retest were 37.86 and 38.19, respectively (ICC: 0.957, 95 %CI: 0.937-0.971, p < 0.001). Furthermore, the MC-DASH version exhibited satisfactory content validity evidenced by its strong correlation (R= 0.903, p < 0.001) with the Chinese DASH. Three major influencing factors were identified from 37 items. The cumulative variance contribution rate of the MC-DASH questionnaire was 75.76 %, confirming its construct validity.

CONCLUSION

The Modified Chinese Disability of Arm, Shoulder and Hand questionnaire has been shown to be a valid, reliable, and practical tool for use in patients with upper extremity injuries.

Assessing Responsiveness of the Trapeziometacarpal Arthrosis Symptoms and Disability Questionnaire

BACKGROUND

This study aimed to assess the responsiveness of the Trapeziometacarpal Arthrosis Symptoms and Disability (TASD) questionnaire after corticosteroid injections and operative management for trapeziometacarpal osteoarthritis (TMC-OA).

METHODS

This longitudinal cohort study included patients with TMC-OA who underwent treatment (corticosteroid injection or surgery). Measurements occurred at baseline and follow-up time points: 6 weeks, 3 months, 6 months, and 1 year. Patient measures were collected electronically using a data repository platform. The TASD is a validated psychometric patient-administered scale. We examined responsiveness by correlating the TASD scores with another known effective indicator of change (shortened Disabilities of the Arm, Shoulder, and Hand [QuickDASH]). Repeated score measurements over time were analyzed using analysis of variance, and correlations between questionnaires were reported with repeated measures correlation and Pearson correlation coefficients.

RESULTS

The nonsurgical cohort undergoing corticosteroid injections included 31 (66%) women and 16 (34%) men, and the surgical cohort included 29 (71%) women and 12 (29%) men. Both the QuickDASH and the TASD captured a statistically significant improvement in symptom burden postoperatively (P < .0001 for both questionnaires), whereas no statistical significance was noted after corticosteroid injections (P = .45 and P = .34, respectively). There was a strong correlation between QuickDASH and TASD questionnaires (r = 0.87, P < .0001).

CONCLUSIONS

The TASD is a promising TMC-OA-specific questionnaire to capture responsiveness following treatment, particularly following surgery. The responsiveness of TASD was demonstrated in the TMC-OA cohort. Further research is needed to define a minimal clinically important difference.

Comprehensive relationship between disease activity indices, mTSS, and mHAQ and physical function evaluation and QOL in females with rheumatoid arthritis

Rheumatoid arthritis (RA) causes significant physical disability. We comprehensively investigated the relationship between RA disease activity (Disease Activity Score 28-C-reactive protein [DAS28-CRP], Simplified Disease Activity Index [SDAI], and Clinical Disease Activity Index [CDAI]), physical function (10-Meter Walk Test [10 MWT], Timed Up and Go test [TUG], Functional Reach Test [FRT], and Disabilities of the Arm, Shoulder, and Hand [DASH]), and quality of life (QOL) (Short-Form 36 [SF-36®]). We also investigated the relationship between van der Heijde's modified Total Sharp Score (mTSS), modified Health Assessment Questionnaire (mHAQ), and physical function and QOL assessments. Among 35 female patients with RA, DAS28-CRP correlated solely with DASH (r = 0.376), while SDAI and CDAI did not correlate with physical function. The mTSS-hand roentgenographic evaluation correlated with TUG (r = 0.359), FRT (r = - 0.415), and DASH (r = 0.533) among physical function assessments. The mHAQ correlated with 10 MWT (r = 0.347), TUG (r = 0.356), FRT (r = - 0.420), and DASH (r = 0.646). DAS28-CRP correlated with six of the eight subscales of SF-36®, and mTSS and mHAQ correlated with only one subscale. RA disease activity assessments may not reflect all physical functions and QOL domains of female patients with RA. Evaluating physical function and QOL in female patients with RA is essential.

Reported Outcomes and Outcome Measures in Proximal Interphalangeal Joint Arthroplasty: A Systematic Review

Purpose: There is a lack of scientific consensus on the best arthroplasty implant option for proximal interphalangeal joint (PIPJ) arthritis, due to diversity in outcome reporting and measurement methods. The development of a standardized core outcome set (COS) and standard outcome measures could mitigate this issue. This study catalogs the reported outcomes and outcome measures found in PIPJ arthroplasty studies, which can be used in the first step of developing a COS. Methods: A database search of MEDLINE, EMBASE, and Web of Science (January 1, 2010, to March 10, 2021) was performed to retrieve studies that reported outcomes of the 3 most common primary PIPJ arthroplasty implants: silicone, pyrocarbon, and metal-polyethylene. The primary objectives of this study include reported outcomes and outcome measures. Secondary objectives include clinimetric properties of outcome measures, study design, and implant types. Results: Fifty articles met inclusion criteria. Of the included studies, 41 (82%) were case series, 8 (16%) were cohort studies, and 1 (2%) was a randomized control trial. Thirty-three unique outcomes were identified. Fifteen (46%) outcomes were clinician-reported and 26 (79%) were patient-reported. Eighteen unique outcome measures were identified. Of the outcome measures, 15 (83%) were patient-reported, 1 (6%) was clinician-reported, and 2 (11%) were reported by both patients and clinicians. Conclusions: Substantial heterogeneity was found in reported outcomes and outcome measures across studies evaluating PIPJ arthroplasty, impeding knowledge translation. The development of a COS for PIPJ arthroplasty is necessary to help compare and pool data across studies, and advance scientific knowledge.

Psychometric evaluation of the disabilities of the arm, shoulder and hand (DASH) in patients with orthopedic shoulder impairments seeking outpatient rehabilitation

STUDY DESIGN

This is a cross-sectional, observational study.

INTRODUCTION

The disability of the arm, shoulder and hand (DASH) questionnaire is an upper-extremity specific outcome measure commonly used in routine clinical care and clinical trials.

PURPOSE OF THE STUDY

Our purposes were to: (1) examine the psychometric properties of the DASH questionnaire using factor analysis, one- and two-parameter item response theory models, and (2) develop a functional staging map illustrating the relationships between the item difficulty hierarchy of the DASH items and the patient's DASH total score.

METHODS

Data from 2724 patients with orthopedic shoulder impairments seeking outpatient physical therapy in 79 clinics in the US were analyzed.

RESULTS

Factor analysis supported a general factor, explaining 62.2% of the total variance. The coverage of DASH items was suitable for patients with shoulder impairments with no ceiling or floor effect. Endorsed items representing the most difficult items were related to feeling less capable, executing recreational activities with force or impact, and performing recreational activities in which you move your arm freely. Items with higher discriminating abilities were those related to do heavy household chores, garden/yard work, and change a light bulb overhead. With a separation index equaled to 4.94, the DASH can differentiate persons into at least 6 statistically distinct person strata. None of the DASH items exhibited differential item functioning by gender or symptom acuity, except two items by age group.

DISCUSSION

Besides a total (summed) final score obtained from a specific measure, the keyform and functional staging plots/maps can be used to assist clinicians in clinical interpretation of the scores.

CONCLUSIONS

Results supported the clinical usage of the DASH questionnaire in patients with orthopedic shoulder impairments seeking outpatient rehabilitation.

Midterm Patient-Reported Outcomes in Wrist Denervation for Post-Traumatic Arthritis

PURPOSE

To analyze patient-reported outcomes and range of motion in a cohort of patients who underwent wrist denervation for advanced wrist osteoarthritis. We hypothesized that improvements in pain and function would be seen with preserved range of motion.

METHODS

Thirty patients underwent wrist denervation for symptomatic stage 1-4 scapholunate advanced collapse (SLAC) arthritis. Patient-Rated Wrist Evaluation, Quick Disabilities of the Arm, Shoulder, and Hand score, and range of motion measurements were assessed preoperatively and at final follow-up.

RESULTS

The mean follow-up duration was 47 months (range, 24-92 months). The mean age at surgery was 65 years, and 96% of the patients were men. The dominant hand was involved in 66% of cases. The SLAC grades of patients involved were as follows: 10% (n = 3) grade 1, 27% (n = 8) grade 2, 60% (n = 18) grade 3, and 3% (n = 1) grade 4. Two patients required conversion to a wrist fusion and were considered failures. In the remaining 28 patients, the mean Patient-Rated Wrist Evaluation total score decreased 22 points (82.4 to 60.9) and the mean Quick Disabilities of the Arm, Shoulder, and Hand score decreased 8 points (32.4 to 24.8). Total arc of wrist flexion-extension showed an average 5° improvement.

CONCLUSIONS

This method of wrist denervation was a viable salvage option for patients with symptomatic SLAC wrist osteoarthritis to preserve motion, decrease pain, and increase function with a low absolute failure rate at mid- to long-term follow-up.

Validity and reliability of the Arabic quick disabilities of the arm, Shoulder and Hand (QuickDASH-Arabic)

BACKGROUND

The QuickDASH is a commonly used upper extremity region-specific outcome measure assessing activity limitation and symptoms. The Arabic version of QuickDASH is available in the official outcome measure website, but no prior studies have examined its psychometric properties.

OBJECTIVE

To examine the psychometric properties of the Arabic QuickDASH in patients with upper extremity musculoskeletal disorders.

METHODS

Participants with upper extremity musculoskeletal disorders were recruited (N = 109) using convenience sampling and completed the Arabic QuickDASH, Numeric Pain Rating Scale, Global Assessment of Function, and RAND 36-item Health Survey in two testing sessions (2-7 days apart). The Arabic QuickDASH structural validity, internal consistency, floor and ceiling effect, test-retest reliability, measurement error, and construct validity were examined.

RESULTS

Exploratory factor analysis indicated a one factor underlying the Arabic QuickDASH. The Arabic QuickDASH had Cronbach's alpha of 0.90 and ICC_2.1 of 0.91 indicating excellent internal consistency and test-retest reliability. None of the participant reached the minimum or the maximum score. The scale's standard error of measurement and minimal detectable change were 7.0 and 16.3. Five out of the six construct validity predefined hypotheses were supported by the results.

CONCLUSION

The Arabic QuickDASH is a unidimensional scale with excellent internal consistency, test-retest reliability and acceptable measurement error. The Arabic Quick DASH is a valid and reliable outcome measure that can be used in Arabic speaking countries with Arabic patients suffering from various upper extremity activity limitations and symptoms.

Effect of Partial and Complete Trapezoid Excision on Radiographic and Functional Results After Abductor Pollicis Longus Suspensionplasty

PURPOSE

We hypothesized that adding complete or partial trapezoid excision is associated with greater radiographic carpal collapse and worse functional outcomes compared with a simple trapeziectomy and abductor pollicis longus suspensionplasty.

METHODS

A total of 69 patients had abductor pollicis longus suspensionplasty (79 hands), 87% of whom were female, mean age 64 years. Scaphotrapezium-trapezoid arthritis noted at surgery was treated with an additional proximal trapezoid excision (PT) in 21 (27%) or complete trapezoid resection (CT) in 22 hands (28%). No trapezoid was excised in 36 hands. The primary outcome was final radiolunate (RL) extension of 15° or greater on lateral radiographs. Logistic regression (for change in RL angle) and linear regression (for continuous variables) with robust variance estimate to account for within-subject correlation (generalized estimating equation method) were used to investigate whether the trapezoid excision groups had an effect on the outcomes of interest. Models were adjusted for age and sex.

RESULTS

Median follow-up was 92 months. Complete trapezoid resection had the most increase in RL angle, but PT had a higher incidence (29% vs 26%) of final RL angle of 15° or greater compared with CT. When stratified into groups with a final RL greater than or less than 15°, the former group had worse total function (Patient-Rated Wrist Evaluation) and Quick-Disabilities of the Arm, Shoulder, and Hand scores. Symptomatic index metacarpal migration was seen in 4 CT and 2 PT wrists (18% and 10%, respectively) and was considered to indicate failure.

CONCLUSIONS

Compared with no trapezoid excised, both PT and CT had a greater incidence of lunate extension of 15° or greater, consistent with radiographic nondissociative-dorsal intercalated carpal instability, which was associated with inferior functional scores. Symptomatic proximal collapse of the index metacarpal was seen in both CT and PT. Further studies should evaluate whether routine excision of the proximal trapezoid is necessary for scaphotrapezoid arthritis, because any disruption of the scaphotrapezoid ligament complex appears to increase risk for developing carpal instability nondissociative-dorsal intercalated carpal instability over time and may be associated with inferior functional results. Complete trapezoid excision is not recommended.

Validity and interpretability of the QuickDASH in the assessment of hand disability in rheumatoid arthritis

Objective of this study is to evaluate the construct validity and the interpretability of the shortened Disability of Arm, Shoulder and Hand Questionnaire (QuickDASH) in the assessment of rheumatoid arthritis (RA) hand disability. Consecutive RA patients were assessed through the QuickDASH and other function and disease activity indices, respectively, the Health Assessment Questionnaire-Disability Index (HAQ-DI) and the Recent-Onset Arthritis Disability questionnaire (ROAD). For each patient were evaluated the tender and swollen 28-joints counts. Interpretability was defined determining cut-off points of impairment in accordance to the Simplified Disease Activity Index (SDAI) definition of disease activity states. A total of 440 patients (89 men and 351 women, mean age of 57.0 ± 12.7 years) were enrolled. Following the SDAI definition, 98 patients (22.3%) resulted in REM, 115 subjects (26.1%) in LDA, 74 patients (16.8%) in MDA, and 153 subjects (34.8%) in HDA. Mean QuickDASH differed significantly between patients classified as remission (REM), low disease activity (LDA), moderate disease activity (MDA), or high disease activity (HDA) (p < 0.001). High correlations were found comparing QuickDASH to composite indices of disease activity and of physical health function: of special interest are the correlations between the comparable dimension of the QuickDASH and the ROAD Upper Extremity Function (rho = 0.876; p < 0.001). The cut-off points for functional categories (SDAI categories as external criterion) resulted: no impairment ≤ 13, 13 < low impairment ≤ 18.5, 18.5 < moderate impairment ≤ 31.5, and high impairment > 31.5. QuickDASH is useful in clinical practice, for its ease of administration, and positively correlates with the disease activity. It may be a surrogate for evaluating upper extremity impairment, disability index and disease control in RA patients.
