Sensor-Based Balance Training with Exergaming Feedback in Subjects with Chronic Stroke: A Pilot Randomized Controlled...

Area of Science:

• Neurorehabilitation
• Biomechanics
• Human-Computer Interaction

Background:

• Stroke significantly impairs balance, affecting daily activities and social engagement.
• Reduced balance performance is a common long-term consequence of stroke.
• Effective rehabilitation strategies are crucial for improving functional outcomes in stroke survivors.

Purpose of the Study:

• To evaluate the impact of sensor-based balance training with exergaming feedback on balance skills in chronic stroke patients.
• To compare the efficacy of sensor-based training against usual care balance training.
• To assess the influence of exergaming feedback on patient motivation and participation in rehabilitation.

Main Methods:

• 21 chronic stroke patients were randomized into sensor-based (SB) or usual care (UC) balance training groups.
• Both groups received 10 add-on sessions; the SB group used exergaming feedback, while the UC group received conventional training.
• Clinical and instrumental evaluations were conducted at baseline, post-intervention, and at one-month follow-up.

Main Results:

• The sensor-based balance training group demonstrated significant improvement in postural stability compared to the usual care group (p=0.02).
• Patients in the sensor-based group reported statistically higher motivational levels (p<0.01).
• No significant differences in overall clinical scores were observed between the groups.

Conclusions:

• Sensor-based balance training shows promise for enhancing postural stability and motivation in stroke survivors.
• The use of exergaming feedback in sensor-based training can improve adherence and participation in rehabilitation.
• This approach is particularly beneficial for patients with lower compliance, potentially increasing engagement in therapy.
