The Use of Virtual Reality to Enhance Upper Limb Prosthetic Training and Rehabilitation

The proposed project is to develop an effective prosthetic training and rehabilitation
regimen, with the use of virtual reality, to return patients to the highest level of
independence and functioning possible. The Computer Assisted Rehabilitation Environment
(CAREN) system (Motek Medical, Netherlands) will be used to immerse patients into real life
situations while providing real time visual feedback of their motion to improve the training
and rehabilitation of upper limb prosthetic users.

The subjects will be asked to participate in two 1-2 hour sessions to test the range of
motion (ROM), activities of daily living ( ADL) and return to duty tasks (RTD) tasks with and
without the use of virtual reality. All amputee subjects will be required to wear their same
preferred prosthetic device for all sessions. The ROM tasks include, elbow flexion/extension,
forearm pronation/supination, shoulder flexion/extension, shoulder abduction/adduction,
shoulder rotation, torso flexion/extension, torso lateral flexion, and torso rotation. The
ADL tasks would include a series of tasks to encompass typical actives one would encounter on
a daily basis such as, drinking from a cup, bilateral and unilateral lift tasks, and a reach
and grasp test. The RTD tasks would include a series of simple tasks service members
typically perform in their daily work routine such as donning and doffing a jacket and
helmet, packing and unpacking a rucksack, and carrying a weapon.

The subjects will be asked to complete each task three times. Prior to performing a task,
when participating in the virtual reality session, the task will be demonstrated on the
virtual screen with an animated model. The motion of the animated model will be determined by
previously collected data to accurately predict the correct motion for each individual. An
avatar of the subject will then be shown on the screen to display the real time motion. The
reflective markers that were strategically placed on the subject will be connected to the
corresponding joint on the virtual avatar to accurately animate the real time motion of the
subject on the virtual screen. The demonstrated model will be shown simultaneously with the
real time avatar to show the accuracy of the subject's performance in relation to the
individualized predicted optimized motion. This will provide instant visual feedback to the
subject.

Inclusion Criteria:

- patients with unilateral transhumeral or transradial amputation

- uses body-powered or myoelectric prosthetic device.

- free of any health aliment that would impair physical function

- must not have any injuries or surgeries on the affected limb within the past 90 days.

- Subjects ,just be able to perform activities of daily living without assistance
