Overview
The investigators propose to evaluate the efficacy of MyoTrain in a prospective clinical study involving 16 individuals with trans-radial upper-limb loss over a period of 206 days. These individuals will be randomized to Group A (Control Group using standard motor imagery training) and Group B (who are provided the MyoTrain system).
The investigators will test three hypotheses:
- The use of MyoTrain results in skills transference to control of the final prosthesis
- The virtual outcome measures in MyoTrain are correlated with real-world functional outcome measures
- The use of MyoTrain results in improved clinical outcomes as measured by functional, subjective and usage metrics
Following a baseline functional assessment, participants will undergo a 30-day pre-prosthetic training period specific to their assigned Group. After this training period, participants will receive their prosthetic device and occupational therapy consistent with the current clinical care standard, after which they will again undergo clinical assessment. Post-device delivery, participants will then complete 3 56-day blocks of at-home prosthesis use, in between which they will return to clinic for assessment.
