Monitoring Daily Upper Limb Movement and Recovery in Adults After Stroke Using Wearable Sensors and Muscle Activity Analysis

What this Trial Is About

Researchers are investigating the daily upper limb movements of people who have had a stroke and how these movements relate to their recovery and impairment levels. This study is part of a larger project called The Natural History of Stroke Recovery. The research aims to develop and validate algorithms and software using wearable sensors called Inertial Measuring Units IMUs to monitor upper limb activity, and to test proprioception acuity based on muscle electrical activity measured by surface electromyography EMG. The study involves observing two groups persons after a stroke and healthy individuals. Participants will wear IMUs to track hand movements, joint range, wrist distance, and other movement features during one or two sessions lasting 1 to 6 hours each. Researchers will also assess muscle synergies and proprioception acuity during active and passive movements using EMG. These observations and tests will be used to understand the relationship between daily arm movements and recovery in stroke patients. Participants will be monitored with detailed movement tracking and clinical assessments such as the Fugl-Meyer Assessment and Action Research Arm Test during the first month after recruitment. The study will collect data on movement count, duration, joint range, angular velocity, and whole body movement time. Stroke patients will be medically stable and able to consent, while healthy volunteers will serve as controls. The total involvement includes a few extended monitoring sessions and clinical tests to assess recovery and motor function.
