Background: Stroke affects postural stability in approximately 85% of stroke survivors. Postural stability is
essential for limb functions. Postural stability training for stroke patients still a challenge because of poor
recovery of both motor and sensory function. Objectives: To determine the effect of visual biofeedback
training on postural instability in chronic stroke patients. Method: 56 hemiplegic patients participated in the
concurrent study. They were randomly assigned into two groups (group A; study group; received visual
biofeedback training in addition to the selected traditional physical therapy rehabilitation program and group B;
control group; received the selected traditional physical therapy rehabilitation program only). The patients
underwent pre- and post-treatment assessment using Biodex balance system for measuring postural stability
(overall, anterior/posterior and medial/lateral stability indices). Results: There were significantly decrease in
overall stability, anterior/posterior, and medial-lateral indices within both groups (P=0.0001 for all
measurements). Percentages of improvement of group A were higher than group B in all measurements
(54.55%, 54.72%, 52.60%, 40.33%, 36.25%, and 30.14%, respectively). Conclusion: Adding visual feedback
training to the traditional physical therapy program is more beneficial to improve the postural instability in
chronic stroke patients.
