Cross-cultural adaptation and Rasch validation of the Slovene version of the Orthotics and Prosthetics Users' Survey (OPUS) Client Satisfaction with Device (CSD) in upper-limb prosthesis users.

Objective: To validate the Slovene version of the Orthotics and Prosthetics Users' Survey (OPUS) 8-item Client Satisfaction with Device (CSD) questionnaire in upper-limb prosthesis users and to further verify measurement properties of this tool with Rasch analysis.

Design: Participants consisted of a convenience sample of 76 adults (54 men) using a prosthesis after unilateral upper-limb amputation who consecutively attended a follow-up visit at our centre.

Methods: After translation and cross-cultural adaptation of the CSD into the Slovene language, we evaluated functioning of the rating scale categories, item fit (internal construct validity), reliability indices and dimensionality, as well as convergent and discriminant construct validity of the questionnaire.

Effect of custom-made and prefabricated orthoses on grip strength in persons with carpal tunnel syndrome.

Background: Based on the literature, patients with carpal tunnel syndrome are suggested to wear a custom-made wrist orthosis immobilizing the wrist in a neutral position. Many prefabricated orthoses are available on the market, but the majority of those do not assure neutral wrist position.

Objectives: We hypothesized that the use of orthosis affects grip strength in persons with carpal tunnel syndrome in a way that supports preference for custom-made orthoses with neutral wrist position over prefabricated orthoses.
