Introduction to Activity-Specific Prostheses

This is the point at which activity-specific prosthetic devices become both helpful and, sometimes, necessary. These devices are designed with a specific task or activity in mind. If the patient’s goals cannot be accomplished with one of the other devices mentioned above, this is where our Arm Dynamics clinicians begin discussing activity-specific prostheses.

We find that for some occupations, an activity-specific prosthesis is the only way to get someone back to work. That was the case for Austin Anderson. Austin had only recently obtained his dream job of one of two full-time tree fallers in Yosemite National Park. After his amputation above his elbow, he wasn’t sure he would be able to return to work. Our Northwest Center built him a custom chainsaw adapter that allowed him to get back to his job.

But it’s not just work that activity-specific devices can help with. Recreational activities, whether they be fitness, leisure or hobby-related, all make life more enjoyable and fulfilling. Even just basic wellness — the ability to keep one’s body well-exercised, without overstraining the sound limb can also have a huge positive physical and mental impact. These reasons, and more, are why activity-specific devices can change lives for the better and, in the case of an amputation, help the user get back to feeling like themselves again.

Max Okun (pictured with his prosthetist at the start of this article) is a great example of someone who needed an activity-specific device for work and play. Max started his job as a personal trainer and was at the gym constantly. As a congenital amputee, Max had been fitted for a prosthetic device as a child but disliked it and had stopped wearing it after a short time. As an adult, when he started spending his days at the gym, he began to experience pain on the sound side of his body — he was overusing his sound arm and wasn’t able to engage the muscles in his affected arm properly. He worked with one of our prosthetists, Julian, to create set of activity-specific devices that would allow him to keep his body fit and working well — and continue his job as a personal trainer. We have a video of Max’s journey with prosthetic devices.

Other activity-specific devices that we have built for our patients include a grip for a bike or ATV handlebar, a gun turret to help with sighting during hunting, or even one that helps the user hold a fishing pole! Activity-specific devices can be especially helpful for children, as they try out different sports and learn what hobbies they like best.

We even helped one of our super-star patients, Jason Koger, by building an activity-specific device for him that allows him to bowl!

We are experts in designing activity-specific devices that enable those with upper limb differences to participate in work, sports, hobbies and other specialized activities.
