Effect of Shoulder Sling Use on Balance and Mobility in Subacute Stroke Patients

This is a cross-over study designed to evaluate the impact of shoulder sling use on balance and functional mobility in patients recovering from stroke in the subacute phase. Participants will be asked to complete three validated functional tests: the Timed Up and Go (TUG) test, the Functional Reach Test (FRT), and the Modified Four Square Step Test (mFSST). Each test will be performed twice, once with the shoulder sling and once without, in randomized order. The study aims to determine whether the sling provides measurable benefits in stability and performance during movement tasks. Data will be collected in rehabilitation centers under the supervision of clinical researchers.
