Myoelectric Prosthesis for Upper Limb Amputees

what is a myoelectric prosthesis?

A myoelectric-controlled prosthesis is an externally powered artificial limb that is controlled using electrical signals generated in the clients own muscles. The hand is controlled using sensors placed within the socket of the prosthesis that detect muscle movements in the residual limb. The client contracts these muscles to open and close the hand of the prosthesis. This can create a much more natural and intuitive way of using a prosthetic arm.

Myoelectric simulation training to provide feedback on muscle contraction to “open” and “close” the prosthesis prior to fitting

Types of myoelectric prostheses:

• Single grip devices - can be either a hand or a hook that allow opening or closing of a single grip position

• Multigrip devices - more sophisticated that offer multiple grip positions allowing combinations of thumb rotation such as lateral grip (between thumb and side of index finger) and pincer grip (between index finger and thumb)

Occupational Therapy is an essential component of rehabilitation for people with an upper limb prosthetic, facilitating optimal performance of daily activities and improving their quality of life.

Occupational Therapists assist with upper limb Prosthetic training by:

• developing and maintaining clients fine motor manipulation/coordination skills - to assist with grasping, lifting and holding objects.

• provide training in the care and use of any prosthetic devices to aid in activities of daily living.

• identifying the client's individual needs and goals and provide rehabilitation to fully utilise the Upper limb prosthetic.

• working collaboratively with prosthetists in trialling potential prosthetic options.

• assist with assessments and report writing for the provision of adaptive technology.
