Comparison of Robot-Assisted Gait Training and Visual Feedback Balance Training on Balance and Gait Outcomes in Patients With Stroke

Stroke is a leading cause of neurological disability worldwide and is frequently associated with gait disturbances and impaired balance. Approximately 80% of stroke survivors experience walking limitations, and many are at increased risk of falls due to postural instability. Restoring balance and independent ambulation is therefore a primary goal of stroke rehabilitation.

Technology-assisted rehabilitation approaches have been increasingly integrated into clinical practice. Robot-assisted gait training provides repetitive, task-specific, and controlled gait patterns that may enhance motor relearning and postural control. Visual feedback balance training using computerized posturography systems aims to improve weight shifting, postural stability, and dynamic balance through real-time feedback.

Although both interventions have demonstrated beneficial effects when combined with conventional rehabilitation, direct comparisons between these two technology-based approaches under similar treatment dosage conditions are limited.

This prospective, randomized, assessor-blinded clinical trial will compare robot-assisted gait training and visual feedback balance training in subacute and chronic stroke patients receiving inpatient rehabilitation. Both interventions are routinely applied in the clinical setting, and no additional experimental procedures will be introduced.

Participants will receive 4 weeks of intervention. Outcomes will be assessed at baseline and after treatment using the Berg Balance Scale as the primary outcome measure, along with secondary measures including functional mobility, gait speed, motor recovery, fear of falling, functional independence, and posturography-derived balance parameters.
