Investigation of the Effect of Orthosis Use for Control of Knee Hyperextension in Chronic Stroke Patients

Withdrawn

• Conditions: Stroke

• Registration Number: NCT05609461
• Lead Sponsor: Hacettepe University

Brief Summary

The aim of this study is to examine the effect of using foot-ankle orthosis at different angles on hyperextension control in stroke patients.

The hypotheses of the study are:

Hypothesis 1:

Ho: The foot-ankle orthosis, which fixes the ankle at different angles (3 degrees of dorsiflexion - 5 degrees of dorsiflexion) in stroke patients, has no effect on the control of knee hyperextension.

H1: Foot-ankle orthosis, which fixes the ankle at different angles (3 degrees of dorsiflexion - 5 degrees of dorsiflexion) in stroke patients, has an effect on the control of knee hyperextension.

Primary Outcome Measures

Name	Time	Method
Kinematic Analysis	Baseline	At the specified anatomical sites of the participants, reflective signs will be placed. The participants will be required to walk 5 meters. The three-dimensional positions of these reflective marks will be captured by the 8-camera Vicon motion capture system. Using the blade software, it will be moved to the computer environment and kinematic data will be collected.
