Study Design:Prospective longitudinal validation studyObjective:To translate and cross-culturally adapt the Oswestry Disability Index (ODI) to the Tamil language (ODI-T), and to evaluate its reliability and construct validity.Summary of Background Data:ODI is widely used as a disease specific questionnaire in back pain patients to evaluate pain and disability. A thorough literature search revealed that the Tamil version of the ODI has not been previously published.Methods:The ODI was translated and cross-culturally adapted to the Tamil language according to established guidelines. 30 subjects (16 women and 14 men) with a mean age of 42.7 years (S.D. 13.6; Range 22 - 69) with low back pain were recruited to assess the psychometric properties of the ODI-T Questionnaire. Patients completed the ODI-T, Roland-Morris disability questionnaire (RMDQ), VAS-pain and VAS-disability at baseline and 24-72 hours from the baseline visit.Results:The ODI-T displayed a high degree of internal consistency, with a Cronbach's alpha of 0.92. The test-retest reliability was high (n=30) with an ICC of 0.92 (95% CI, 0.84 to 0.96) and a mean re-test difference of 2.6 points lower on re-test. The ODI-T scores exhibited a strong correlation with the RMDQ scores (r = 0.82) p<0.01, VAS-P (r = 0.78) p<0.01 and VAS-D (r = 0.81) p<0.01. Moderate to low correlations were observed between the ODI-T and lumbar ROM (r = -0.27 to -0.53). All the hypotheses that were constructed apriori were supported.Conclusion:The Tamil version of the ODI Questionnaire is a valid and reliable tool that can be used to measure subjective outcomes of pain and disability in Tamil speaking patients with low back pain.

BackgroundThe Patient Rated Elbow Evaluation (PREE) was developed as an elbow joint specific measure of pain and disability and validated with classical psychometric methods. More recently, Rasch analysis has contributed new methods for analyzing the clinical measurement properties of self-report outcome measures. The objective of the study was to determine aspects of validity of the PREE using the Rasch model to assess the overall fit of the PREE data, the response scaling, individual item fit, differential item functioning (DIF), local dependency, unidimensionality and person separation index (PSI).MethodsA convenience sample of 236 patients (Age range 21–79 years; M: F- 97:139) with elbow disorders were recruited from the Roth│McFarlane Hand and Upper Limb Centre, London, Ontario, Canada. The baseline scores of the PREE were used. Rasch analysis was conducted using RUMM 2030 software on the 3 sub scales of the PREE separately.ResultsThe 3 sub scales showed misfit initially with disordered thresholds on17 out of 20 items), uniform DIF was observed for two items (“Carrying a 10lbs object” from specific activities subscale for age group; and “household work” from the usual activities subscale for gender); multidimensionality and local dependency. The Pain subscale satisfied Rasch expectations when item 2 “Pain – At rest” was split for age group, while the usual activities subscale readily stood up to Rasch requirements when the item 2 “household work” was split for gender. The specific activities subscale demonstrated fit to the Rasch model when sub test analysis accounted for local dependency. All three subscales of the PREE were well targeted and had high reliability (PSI >0.80).ConclusionThe three subscales of the PREE appear to be robust when tested against the Rasch model when subject to a few alterations. The value of changing the 0–10 format is questionable given its widespread use; further Rasch-based analysis of whether these findings are stable in other samples is warranted.

Background and Purpose:Elbow fractures amount to 4.3% of all the fractures. The elbow is prone to stiffness after injury and fractures can often lead to significant functional impairment. Rehabilitation is commonly used to restore range of motion (ROM) and function. Practice patterns in elbow fracture rehabilitation have not been defined. The purpose of this study was to describe current elbow fracture rehabilitation practices; and compare those to the existing evidence base.Methods:Hand therapists (n=315) from the USA (92%) and Canada (8%) completed a web-based survey on their practice patterns and beliefs related to the acute (0-6 weeks) and functional (6-12 weeks) phases of elbow fracture rehabilitation.Results:More than 99% of respondents agreed that fracture severity, co-morbidities, time since fracture, compliance with an exercise program, psychological factors, and occupational demands are important prognostic indicators for optimal function. Strong agreement was found with the use of patient education (95%) and active ROM (86%) in the acute stage while, home exercise programs (99%), active ROM (99%), stretching (97%), strengthening (97%), functional activities (ADLs and routine tasks) (97%), passive ROM (95%), and active assisted ROM (95%) were generally used in the functional stage. The most commonly used impairment measures were goniometry (99%), Jamar dynamometry (97%), and hand held dynamometry (97%). Agreement on the use of patient-reported outcome measures was very minimal (1.3%- 35.6%).Conclusions:Exercise, education, and functional activity have high consensus as components of elbo fracture rehabilitation. Future research should focus on defining the optimal dosage and type of exercise/activity, and establish core measures to monitor outcomes of these interventions.

Study Design Prospective cohort study. Objective To evaluate the internal consistency, concurrent construct validity, longitudinal validity, sensitivity to change, and factor structure of the Patient-Rated Elbow Evaluation form (PREE), the patient-reported form of the American Shoulder and Elbow Surgeons Elbow Questionnaire (pASES-e), and the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) in a diverse group of patients who had surgery for various elbow pathologies. Background Measuring functional outcomes after surgical procedures of the elbow requires valid patient-reported pain and disability questionnaires. The PREE, the pASES-e, and the DASH are commonly used questionnaires. There is, however, insufficient evidence available concerning their validity and sensitivity to change. Methods Data were prospectively collected from 128 patients (mean ± SD age, 46.5 ± 12.8 years) post-elbow surgery. Patients completed the PREE, the pASES-e, the DASH, and the Medical Outcomes Study 36-Item Short-Form Health Survey at baseline (first visit after surgery) and 6 months postsurgery. Concurrent construct validity, longitudinal validity, sensitivity to change, and factor structure were analyzed. Results Concurrent construct validity was demonstrated by confirmation of expected relationships; the strongest correlations were observed between the PREE pain score, the PREE total score, the pASES-e pain score, and the DASH score (r = 0.73–0.87). The pASES-e function score correlated the least with other constructs. Longitudinal validity demonstrated similar findings: the pASES-e pain change score and PREE change score were most strongly correlated, and the pASES-e function change score and DASH change score were moderately to weakly correlated. All 3 patient-reported questionnaires demonstrated a large effect size and standardized response means greater than 1.0. Structural validity was supported for the PREE (R2 = 77.2%, 4 factors) and the pASES-e (R2 = 74.4%, 4 factors), but not for the DASH (R2 = 71.3%, 5 factors). Conclusion The PREE, the pASES-e, and the DASH have acceptable validity and sensitivity to change. The pASES-e function subscale is the least sensitive to change and is less correlated to other measures. J Orthop Sports Phys Ther 2013;43(4):263–274. Epub 13 March 2013. doi:10.2519/jospt.2013.4029
