Study Tests Exoskeletons That Let Therapists and Stroke Patients Share Movement Feedback
A new study tested paired exoskeletons that transmit movement data between a therapist and a stroke patient walking on separate treadmills. The system aims to improve gait correction during rehabilitation sessions.

Each person walked on a separate treadmill while wearing the devices, allowing the therapist to sense the patient's movements in real time. The setup enabled the therapist to adjust guidance based on subtle changes in the patient's gait. Researchers said the shared feedback supported more precise corrections than traditional visual or verbal instructions alone.
How the System Works Each exoskeleton recorded hip and knee joint angles and transmitted those measurements to the paired device. The receiving exoskeleton applied corresponding forces, creating a physical link between the two users without direct contact.
The study reported that patients completed walking trials with measurable changes in step length and symmetry when the feedback loop was active. Therapists could increase or decrease resistance through the system to guide specific movements.
Further trials are planned to measure long-term improvements in walking speed and balance after multiple sessions. The approach may be tested with additional patient groups recovering from neurological injuries.
