Brief summary
Walking disorder is the most common and concerning issue for individuals with stroke. Previous studies have often used improvements in walking speed and distance as reference indicators for the advancement of gait performance in individuals with stroke. However, for individuals with chronic stroke, considering gait symmetry and variability to enhance gait quality as the primary intervention target may be more crucial. According to a literature review, it can be inferred that the application of biofeedback to detect gait quality may be an effective approach to improve gait symmetry and variability in individuals with stroke. However, there is still insufficient research evidence on this issue. Therefore, this study aims to investigate the effects of a kinematic biofeedback device system, which detects hip joint angles, on gait quality in individuals with chronic stroke.
Interventions
Gait training include treadmill and overground walking. The biofeedback device system will provide real-time feedback on hip extension angles.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Gait symmetry | 1 day | Using GAITRite system to measure the symmetry of spatiotemporal parameters, including step length, step width, single support time, and double support time. Calculate the gait symmetry using following formula: Gait symmetry = affected side/ unaffected side. |
| Gait variability | 1 day | Using GAITRite system to measure the coefficient of variation (CV). The mean and standard deviation will be used to calculate the coefficient of variation (CV). CV = standard deviation / mean \* 100% |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Propulsive force | 1 day | Using Force plate to measure the ground reaction force |
