Effects of interactive visual feedback training on post-stroke pusher syndrome: a pilot randomized controlled study.

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Clinical Trials

Background:

• Pusher syndrome is a neurological condition following stroke, characterized by active pushing away from the less affected side.
• Impaired balance and motor control are significant challenges for stroke survivors with pusher syndrome.
• Effective rehabilitation strategies are crucial for improving functional outcomes in these patients.

Purpose of the Study:

• To evaluate the efficacy of a computer-generated interactive visual feedback (CIVF) training program for pusher syndrome recovery.
• To compare the effects of CIVF training with traditional mirror visual feedback (MVF) training.
• To assess the impact of these interventions on balance and motor control.

Main Methods:

• A pilot randomized controlled study design was employed.
• 12 stroke patients with pusher syndrome were randomized into two groups: CIVF training (N=7) and MVF training (N=5).
• Outcome measures included the Scale for Contraversive Pushing, Berg Balance Scale, and Fugl-Meyer Assessment, assessed pre- and post-intervention.

Main Results:

• Both CIVF and MVF training led to significant improvements in reducing pusher syndrome severity, enhancing balance, and improving lower extremity motor control.
• The CIVF group demonstrated significantly greater improvements in pusher syndrome severity (p < 0.01) and balance (p < 0.05) compared to the MVF group.
• Specific improvements noted: decreased pusher syndrome scores, increased balance scores, and higher motor control scores in both groups, with superior results in the CIVF arm.

Conclusions:

• Computer-generated interactive visual feedback training is an effective intervention for stroke patients with pusher syndrome.
• CIVF training offers superior benefits for pusher syndrome recovery and balance improvement compared to mirror visual feedback training.
• This pilot study suggests that CIVF training is a promising rehabilitation tool for enhancing functional recovery in stroke survivors.
