Comparative StudyFunctional outcomes from inpatient rehabilitation after traumatic brain injury: how do Hispanics fare?
To examine the relation between Hispanic ethnicity and rehabilitation outcome in traumatic brain injury (TBI) survivors. ⋯ Hispanics showed significantly reduced long-term functional outcome after rehabilitation relative to whites. Rehabilitation professionals should recognize the possible impact of individual differences and diverse sociodemographic, injury, and rehabilitation characteristics so that differential health outcomes among TBI survivors can be reduced or eliminated.

The relationship between electrodiagnostic findings and patient symptoms and function in carpal tunnel syndrome.
To examine whether, in patients with carpal tunnel syndrome (CTS), electrodiagnostic study findings were associated with patient symptom severity and functional limitations after controlling for potentially confounding variables including depression, somatization, and pain-related catastrophizing. ⋯ Electrodiagnostic findings and patient CTS-related symptoms and function appear to be independent measures. Clinicians and researchers interested in CTS outcomes need to assess both.

The Foot Posture Index: Rasch analysis of a novel, foot-specific outcome measure.
To investigate the internal construct validity of a clinician-assessed measure of foot position, the Foot Posture Index (FPI), versions FPI-8 and FPI-6. ⋯ The original FPI-8 showed significant mismatching to the model. The 2 items in the FPI-8 that were identified as problematic in clinical validation studies were also found to be contributing to the lack of fit to the Rasch model. The finalized 6-item instrument showed good metric properties, including good individual item fit and good overall fit to the model, along with a lack of differential item functioning. This analysis provides further evidence for the validity of the FPI-6 as a clinical instrument for use in screening studies and shows that it has the potential to be analyzed using parametric strategies.

Measuring muscle strength for people with chronic obstructive pulmonary disease: retest reliability of hand-held dynamometry.
To evaluate the retest reliability and quantify the degree of measurement error when measuring isometric muscle strength with a hand-held dynamometer for people with chronic obstructive pulmonary disease (COPD). ⋯ Hand-held dynamometry is suitable for monitoring change in muscle strength and testing hypotheses for groups of people with COPD. However, hand-held dynamometry is not likely to detect changes in muscle strength for a person with COPD.
