Wearable Robot with Balloon Tech Offers Hope for Stroke Recovery

Quick Summary

• Harvard researchers have designed a wearable robotic vest aimed at aiding individuals with stroke or ALS in regaining crucial upper limb mobility.
• The device uses inflatable balloons under the arms,powered by machine learning and physics-based models,to assist in movements like raising or lowering the arms.
• In tests, the wearable robot identified intended shoulder movements with an accuracy of 94.2%.It also reduced exertion force by 31.9% compared to previous models.
• Nine participants (five stroke survivors and four ALS patients) reported improved shoulder elevation, wrist extension, and decreased fatigue during rehabilitative tasks like reaching for objects.
• Feedback from users helped refine the device’s usability,making movement assistance feel more natural while reducing strain on other body parts during usage.
• The soft robotic vest integrates sensors across its surface that detect subtle movements analyzed by machine learning algorithms before assisting with intentional actions using pressure-controlled balloon actuators.
• Results suggest potential applications in physical therapy and rehabilitation for improving everyday activities such as brushing teeth or drinking water.
• The findings were published in Nature Communications.
