Passive robotter til genoptræning af slagtilfælde

The purpose of this study is to examine the feasibility and effectiveness of a novel, multimodal approach that combines passive devices with noninvasive neuromuscular stimulation for upper extremity rehabilitation after stroke.

Detaljeret beskrivelse

About 800,000 individuals suffer from a stroke every year in the United States. The majority of stroke survivors often experience lingering deficits in upper extremity function. High-end robotic devices can improve outcomes and clinical productivity; however, these devices are expensive and bulky, making them not practical for many clinical or home environments. This study aims to evaluate the feasibility of low-cost non-motorized devices for stroke rehabilitation in a long-term intervention. The intervention will involve training with a table-top, semi-passive (i.e., no motors) exercise equipment called SepaRRo and commonly-used neuromuscular stimulation. The stimulation will be provided during functional activities using a custom controller (NeuRRoFES) to trigger stimulation. These instruments are designed to provide flexible, compliant assistance/resistance to improve upper extremity function and can be used in a home setting. The study will measure technical feasibility (e.g., qualitative survey, adherence, time on task, retention, ability to perform tasks) as well as clinical feasibility (i.e., changes in biomechanical, neurophysiological, and functional measures) of an intervention with these devices in stroke survivors. The findings aim to support the development of affordable, home-use rehabilitation systems for stroke patients.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Robotic Intervention

Participants will receive upper extremity rehabilitation using SepaRRo and NeuRRoFES 2-5 times per week for 2-6 weeks

Participants will perform functional movements (e.g., reach for targets) with their extremities. During movements, the devices will be used to assist or resist their motion. Participants may receive biofeedback of their movements to better engage them in training. Participants may receive assistance from the devices (including neuromuscular stimulation) and/or their less-impaired limb.

Upper extremity Fugl-Meyer Score
Tidsramme: Baseline and post-intervention measurements will be taken on separate days, within a week of the first and last sessions of the intervention, respectively.

Changes in upper extremity Fugl-Meyer score from before the intervention (from baseline) to after its completion using publicly available scoring sheets. The Fugl-Meyer score is a measure of functional impairment and runs from 0 to 66 points, with higher numbers reflecting better outcome.

Baseline and post-intervention measurements will be taken on separate days, within a week of the first and last sessions of the intervention, respectively.
