EMG-Controlled Game to Retrain Upper Extremity Muscle Activation Patterns Following Stroke

Not Applicable

Recruiting

• Conditions: Stroke
• Interventions: Behavioral: practice muscle activation patterns; Behavioral: task practice

• Registration Number: NCT05628324
• Lead Sponsor: VA Office of Research and Development

Brief Summary

The purpose of this study is to develop and test if upper limb task practice and muscle activity training improve upper limb function in stroke survivors. Participants will be asked to come to the laboratory 23 times (approximately 3 times a week) over 2.5 months to receive upper limb task practice, muscle activity training, and/or upper extremity functional assessments.
