The purpose of this study was to examine the internal construct validity of the Arabic version of the Lower Extremity Functional Scale (20-item Arabic LEFS) using Rasch analysis. ⋯ Rasch analysis did not support the 20-item Arabic LEFS as a unidimensional measure of lower extremity function. The refined 15-item Arabic LEFS met all the requirement of the Rasch model and hence is a valid objective measure of lower extremity function. The Rasch-validated 15-item Arabic LEFS needs to be further tested in an independent sample to confirm its fit to the Rasch measurement model. Implications for Rehabilitation The validity of the 20-item Arabic Lower Extremity Functional Scale to measure lower extremity function is not supported. The 15-item Arabic version of the LEFS is a valid measure of lower extremity function and can be used to quantify lower extremity function in patients with lower extremity musculoskeletal disorders.

Observational Study
Tracking changes in glenohumeral joint position in acute post-stroke hemiparetic patients: an observational study.
The majority of people develop hemiparetic shoulder inferior subluxation following stroke, but the timing of onset is unknown. This study aimed to assess changes in glenohumeral joint centre of rotation (GHJC) during the first six weeks following stroke. ⋯ Minimal changes in glenohumeral joint positioning occurs early post-stroke. Clinicians should consider changes in glenohumeral joint position for both non- and hemiparetic sides during the early rehabilitation phase following stroke. Implications for rehabilitation Changes occur in glenohumeral joint centre of rotation (GHJC) position between hemiparetic and non-hemiparetic sides early in people with mild stroke. Clinicians need to be aware of early GHJC positional changes. Early GHJC positional changes may contribute to the development of hemiparetic shoulder pain (HSP), anterior humeral subluxation and glenohumeral joint impingement. Clinicians should employ current best practice guidelines which promote safe positioning and handling of the upper limb to minimise subluxation forces and potential trauma to the passive restraints of the shoulder in the acute phase following stroke, to reduce the possibility of glenohumeral subluxation in the short term.

People with fibromyalgia experience a disagreement between patient-reported (i.e., subjective) and performance-based (i.e., objective) status. This study aimed to (i) corroborate the discordance between subjectively and objectively measured physical function and (ii) examine whether catastrophizing (worrying, pain magnifying, and helpless cognitions) and self-efficacy (believing capable to manage pain) are independently associated with this discordance. ⋯ Subjective physical function is more impaired than objective physical function in fibromyalgia, yet both are markedly impaired. Catastrophizing cognitions are associated with this discordance. In particular, high catastrophizing may promote a feeling of reduced ability to do meaningful activities of daily living (i.e., restrictions) that people with fibromyalgia are actually able to. Therefore, catastrophizing should be assessed and potentially targeted when focusing on improving physical function in fibromyalgia. Implications for rehabilitation Rehabilitation should focus on physical exercise programs to help women with fibromyalgia to improve their reduced physical function. In rehabilitation settings, physical function of people with fibromyalgia should be evaluated by both subjective and objective assessments to fully understand physical functioning and to test the existence of discordance between both assessments. In case of a large discordance between subjective and objective physical function, a physical exercise program might be better complemented with cognitive management techniques to reduce catastrophizing and subjective physical dysfunction. When people with fibromyalgia experience high levels of catastrophizing, subjective assessments seem to be poor indicators of physical function.
