Supporting upper limb movements with a soft robot after a brachial plexus injury

A research article describing a wearable soft robotic exosuit designed to assist multi-joint upper‑limb movements after brachial plexus injury, and what readers can expect to learn about its design and immediate functional effects.

Key Takeaways
  • Soft wearable exosuit improved active arm range of motion by 80–180% in single-session testing
  • Static muscular endurance increased by about 160% while perceived effort dropped nearly to zero
  • Action Research Arm Test scores improved by an average of 4.5 points and movements became smoother
