Brief Summary

This project is a continuing study from the FEATHERS project (NCT02290353) which focuses on developing novel home therapy program for persons with hemiparesis. This study will focus on examining motor behaviour and adaptation in neurodevelopmental hemiparesis (cerebral palsy, acquired brain injury (ABI)). New algorithms for motion control involved in encouraging active movement are developed and will be tested, but the study has the same therapeutic goal and focus as the original FEATHERS project of creating an engaging at-home bimanual upper limb training program. By incorporating existing gaming technology, we hope to discover novel ways to adapt commercial motion tracking controllers and visual feedback into engaging rehabilitative learning tools. This study will focus on a basic science aspect of human bimanual movements that can be incorporated into future applications of the full FEATHERS project devices. We believe that together these approaches will yield interventions that significantly improve functional ability and lead to improved quality of life.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: PARTICIPANT
• Masking Details: Participant intervention arm will be randomized and they will not be told which whether the treatment is being applied in the current set. However, they will be instructed of the task goal at the beginning of the session and will be told that we will be modifying visual feedback to help improve reaching symmetry in some manner.
