UULEX Reliability in Individuals With Stroke

This study was designed to determine the test-retest reliability of the Unsupported Upper Limb Exercise Test (UULEX) in individuals with stroke. Motor impairments following stroke, particularly reductions in upper limb muscle strength, motor control, and functional performance, may adversely affect individuals' activities of daily living and functional independence. Therefore, the assessment of upper limb performance using reliable and feasible methods is important for planning and monitoring the rehabilitation process. The UULEX is an incremental, performance-based, easy-to-administer, and low-cost field test developed to assess upper limb exercise capacity. Although the UULEX has been used in different clinical populations, evidence regarding its test-retest reliability in individuals with stroke is limited. In this study, the UULEX will be administered twice to individuals with stroke at a predetermined interval, and the consistency between the two measurements will be evaluated to determine its test-retest reliability. It is hypothesized that the UULEX will demonstrate high test-retest reliability in individuals with stroke. The findings of this study are expected to provide evidence regarding the reliability of the UULEX as a clinical assessment tool for evaluating upper limb exercise capacity in individuals with stroke.
