Neuro-Intermuscular Coordination Enhancement (NICE) Rehabilitation Through Human-Machine Interaction in Chronic Stroke
Sponsored by University of Houston
About this study
The objective of this study is to develop Neuro-Intermuscular Coordination Enhancement (NICE) rehabilitation, a novel neuromuscular control signal-guided strategy that visually guides stroke patients to individually activate motor modules through human-machine interaction. Ultimately, the development will lead to better clinical motor recovery, better quality of life, and lowered healthcare costs associated with the impairment.
Stroke is the leading cause of severe long-term disability, affecting 9.4 million Americans. Each year around 800,000 people suffer a stroke even in the USA. Chronic upper extremity motor impairment is a major contributing factor to disability; functional use of the affected UE in daily life is a key factor for increased independence, return to work, and overall quality of life. Thus, effective and innovative treatment to address long-term disability is both a major public health need and an economic necessity. This study is an early-stage, randomized controlled rehabilitation trial designed to evaluate the clinical effects, feasibility, transfer of therapeutic gains, and exploratory neurophysiological correlates of Neuro-Intermuscular Coordination Enhancement (NICE) in individuals with c…

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.
Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
