🦾 Wearable Robot Helps Stroke Patients Move Arms

A Harvard team has unveiled a soft, vest-like "wearable robot" that assists stroke and ALS patients with shoulder motion.

Inflatable balloons tucked under the armpit rhythmically expand and contract to guide the arm, while machine-learning and physics models interpret the wearer's intended movement and tailor the support. In early trials, the system correctly predicted shoulder motions 94.2% of the time and reduced the muscle effort required to lower the arm by 31.9% versus an earlier prototype.
