Robotic Device for Out-of-Clinic Post-Stroke Hand Rehabilitation

Due to the ageing population and an increasing number of stroke patients, we see potential future rehabilitation in telerehabilitation, which might alleviate workload physiotherapists occupational therapists. In order enable use devices aimed for home independent need be developed. This paper describes design a robotic device post-stroke wrist finger evaluates movement it can perform. Six healthy subjects were tested three experimental conditions: performing coupled fingers from flexion extension without device, with passive active device. The kinematics hand captured using Optotrak Certus motion capture systems tracking 11 infrared light-emitting diode (LED) markers. results are presented form base-line trajectories all middle (MF) joints. addition, deviations between conditions across computed metacarpophalangeal (MCP) joint fingertip MF pinkie (PF) finger. Deviations trajectory measurement protocols root-mean-square deviation (RMSD) values indicate that hand, imposed by developed is comparable unconstrained subjects, especially when moving into extension, opening hand.
