Background A paucity of information exists on the psychometric properties of several balance outcome measures. With the exception of the Modified Functional Reach Test, none of these balance outcome measures were developed specifically for the population with spinal cord injury (SCI). A new balance assessment tool for people with SCI, the Activity-based Balance Level Evaluation (ABLE scale), was developed and tested. Objective The purposes of this study were: (1) to develop a scale capturing the wide spectrum of functional ability following SCI and (2) to assess the initial psychometric properties of the scale using a Rasch analysis. Design A methodological research design was used to test the initial psychometric properties of the ABLE scale. Methods The Delphi technique was used to establish the original 28-item ABLE scale. People with SCI at each of 4 centers (n=104) were evaluated using the ABLE scale. A Rasch analysis was conducted to test for targeting, item difficulty, item bias, and unidimensionality. An analysis of variance was completed to test for discriminant validity. Results The Rasch analysis revealed a scale with minimal floor and ceiling effects and a wide range of item difficulty capturing the large scope of functional capacity after SCI. Multiple redundancies of item difficulty were observed. Limitations All raters were experienced physical therapists, which may have skewed the results. The sample size of 104 participants precluded a principal component analysis. Conclusion Development of an all-inclusive clinical instrument assessing balance in the SCI population was accomplished using the Delphi technique. Modifications of the ABLE scale based on the Rasch analysis yielded a 28-item scale with minimal floor or ceiling effects. Larger studies using the revised scale and factor analyses are necessary to establish unidimensionality and reduction of the total item number.

Abstract Background The Catquest-9SF questionnaire is a patient reported outcome measure that quantifies the visual benefits from cataract surgery. The purpose of this study was to translate and adapt the Catquest-9SF questionnaire for France, to assess its psychometric properties via Rasch analysis, and to assess its validity when completed using an electronic notepad. Methods The Catquest-9SF questionnaire was translated following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Catquest-9SF and clinical data were collected from patients before and after routine cataract surgery. All questionnaire data were collected via an electronic notepad. Rasch analysis was performed to assess psychometric properties, and sensitivity to change was analysed for patients with complete paired pre- and post-operative questionnaires. Results A complete filled-in preoperative questionnaire was obtained for 848 patients. Rasch analysis showed good precision (person separation: 2.32, person reliability: 0.84), ordered category probability curves, no item misfit, and unidimensionality. The respondents were slightly more able than the level of item difficulty (targeting: −1.12 logits). Sensitivity was analysed on 211 paired questionnaires, and the postoperative questionnaires showed a clear ceiling effect. The effect size was 2.6. The use of an electronic notepad for completing the questionnaire worked out very well after some adjustments. Conclusions The French version of Catquest-9SF has good psychometric properties and is suitable for use in French-speaking patients. The use of the Catquest-9SF questionnaire in an electronic format showed good validity.

To enable clinicians to make an informed choice when selecting outcome measures to demonstrate the effectiveness of comprehensive rehabilitation, what objective criteria should be examined? This article considers the importance of the purpose, content, psychometric properties and ease of administration in selecting measures. Several outcome instruments evaluating self-care and mobility, mental health interventions and comprehensive rehabilitation approaches are examined with reference to these selection criteria. Measures that evaluate physical, psychological and social functioning, taking into account the desired outcome of the patient and his/her carers, are highlighted.

Background: Chronic localized pain and decreased upper extremity mobility commonly occur following breast cancer surgery and may persist despite use of pain medication and physical therapy.Purpose: We sought to determine the value of myofascial massage to address these pain and mobility limitations.Setting: The study took place at a clinical massage spa in the U.S. Midwest. The research was overseen by MetroHealth Medical Center’s Institutional Review Board and Case Center for Reducing Health Disparities research staff.Participants: 21 women with persistent pain and mobility limitations 3–18 months following breast surgery.Research Design: We conducted a pilot randomized controlled trial where intervention patients received myofascial massages and control patients received relaxation massages.Intervention: Intervention participants received 16 myofascial massage sessions over eight weeks that focused on the affected breast, chest, and shoulder areas. Control participants received 16 relaxation massage sessions over eight weeks that avoided the affected breast, chest, and shoulder areas. Participants completed a validated questionnaire at the beginning and end of the study that asked about pain, mobility, and quality of life.Main Outcome Measures: Outcome measures include change in self-reported pain, self-reported mobility, and three quality-of-life questions.Results: At baseline, intervention and control participants were similar in demographic and medical characteristics, pain and mobility ratings, and quality of life. Compared to control participants, intervention participants had more favorable changes in pain (-10.7 vs. +0.4, p < .001), mobility (-14.5 vs. -0.8, p < .001), and general health (+29.5 vs. -2.5, p = .002) after eight weeks. All intervention and control participants reported that receiving massage treatments was a positive experience.Conclusions: Myofascial massage is a promising treatment to address chronic pain and mobility limitations following breast cancer surgery. Further work in several areas is needed to confirm and expand on our study findings.

The Rasch Model

Background The original 20-item Upper Extremity Functional Index (UEFI) has not undergone Rasch validation. Objective The purpose of this study was to determine whether Rasch analysis supports the UEFI as a measure of a single construct (ie, upper extremity function) and whether a Rasch-validated UEFI has adequate reproducibility for individual-level patient evaluation. Design This was a secondary analysis of data from a repeated-measures study designed to evaluate the measurement properties of the UEFI over a 3-week period. Methods Patients (n=239) with musculoskeletal upper extremity disorders were recruited from 17 physical therapy clinics across 4 Canadian provinces. Rasch analysis of the UEFI measurement properties was performed. If the UEFI did not fit the Rasch model, misfitting patients were deleted, items with poor response structure were corrected, and misfitting items and redundant items were deleted. The impact of differential item functioning on the ability estimate of patients was investigated. Results A 15-item modified UEFI was derived to achieve fit to the Rasch model where the total score was supported as a measure of upper extremity function only. The resultant UEFI-15 interval-level scale (0–100, worst to best state) demonstrated excellent internal consistency (person separation index=0.94) and test-retest reliability (intraclass correlation coefficient [2,1]=.95). The minimal detectable change at the 90% confidence interval was 8.1. Limitations Patients who were ambidextrous or bilaterally affected were excluded to allow for the analysis of differential item functioning due to limb involvement and arm dominance. Conclusion Rasch analysis did not support the validity of the 20-item UEFI. However, the UEFI-15 was a valid and reliable interval-level measure of a single dimension: upper extremity function. Rasch analysis supports using the UEFI-15 in physical therapist practice to quantify upper extremity function in patients with musculoskeletal disorders of the upper extremity.
