Robot-Aided Assessment and Rehabilitation of Upper Extremity Function After Stroke
Purpose
The purpose of this clinical trial is to investigate the efficacy of a hybrid-based rehabilitation program for the upper extremity(UE) combining the interventions- Functional Electrical Stimulation (FES) and Robotic rehabilitation in individuals with chronic stroke. The main question it aims to answer is if the Hybrid multi-muscle FES+Robot upper extremity rehabilitation is more effective in improving the upper extremity motor impairments and function as compared to robotic upper extremity training alone.

Experimental Hybrid multi-muscle FES+Robot |
Participants will be receive hybrid upper extremity training involving the combination of REACH robotic device and multi-muscle FES. Water based electrodes will be positioned on the Triceps, Anconeus, wrist and finger extensors. Stimulation intensity of FES will be set at the participants tolerance level. The FES induced muscle contraction timing will be triggered in synchrony with the robotic movement. The training will be a multi-directional reach movement and hand opening re-training. |

Detailed Description
Individuals with chronic stroke(> 6months after stroke) will be recruited. All participants will complete clinical and kinematic assessments at 2 time points(baseline and after 6 weeks training). Each participant will receive 18 sessions of 60 minute upper extremity training over 6 weeks. Study participants will be randomly assigned to receive either of the following upper extremity training- 1. Hybrid multi-muscle FES+Robot training group or 2.Robot only training group. The following clinical assessments to measure the motor impairments and functional recovery will be performed: Fugl-Meyer Upper Extremity, Modified Ashworth Scale, and Wolf Motor Function Test. Kinematic assessments will be conducted using the REACH robotic device and the Kinereach/trakStar system. The following kinematic parameters will be collected: Smoothness, Range of Motion, and Speed.
