Step 1: Have a thorough discovery chat with your user
Before you dive into any palpation for muscle activity with a prospective user, plan to have a thorough
discussion with them about what they can feel and do with their limb. Forget instructing them to imagine
isolating wrist flexion and extension or simple elbow up/down (we know—it can be hard to change old habits)
but instead, have them tell you ALL of what their finger, hand, wrist, elbow, etc. perceptions are.
Why? Well, this is a great way for both you clinicians AND your users to work together, explore and learn what
intuitive motions and feelings they may want to use for their prosthesis control. Let them tell you what they
can do. And don’t mistakenly limit them by cornering them into the old “flex/extend” box.
GOALS OF THIS DISCUSSION ARE TO DETERMINE WHAT MUSCLE CONTRACTIONS
(MOTIONS) THE USER FEELS:
1.
Are intuitive to use for prosthesis control.
2.
Can be performed consistently.
3.
Are unique for each intended prosthesis action.
