Study Details

Brief summary:

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:

1. The use of MyoTrain results in skills transference to control of the final prosthesis
2. The virtual outcome measures in MyoTrain are correlated with real-world functional outcome measures
3. 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.

Interventions and Outcome Measures

Arms

experimental: Experimental

Participants will be provided with the take-home MyoTrain system, which includes the MyoTrain armband, iPad, and MyoTrain software. Participants will progress through the training modules of the MyoTrain software, starting with eliciting paired single DoF antagonistic movements and ending with the proportional control of complex, 2-DoF hand and wrist movements.

active comparator: Control

Participants will be provided motor imagery exercises that involve brief attempts to move the missing limb in a similar manner to how they would control their pattern recognition system to strengthen their muscles. These exercises do not involve any real-time control feedback.

Interventions

MyoTrain

MyoTrain is a virtual prosthesis control training system. From a hardware perspective it consists of an Apple iPad tablet computer and an eight-channel EMG armband, based on the Element electrode platform, which interfaces with the tablet via Bluetoothâ„¢. From a software perspective, MyoTrain was developed in the cross-platform Unity 4.0 game development environment.

Motor Imagery

Motor imagery describes the process by which a prosthesis user mentally simulates the execution of a desired limb movement and activates the musculature of the residual limb that would generate the desired movement.

Primary outcome measure

  • Mean Prosthesis Wear Duration [ Time Frame: Days 35-206 ]
