These straps secure the forearm to the arm supports on a Grillo gait trainer. For a client who cannot keep an arm in place without thinking about it, the strap takes that job off them, so the attention that was going into holding the arm down can go into the stepping pattern instead.
Clinically it helps where tone pulls an arm away, where sensation or awareness is reduced on one side, or where a client fatigues through the shoulder before the legs give out. Because the hold is adjustable, you can start firm and ease it back across a block of sessions as the client takes over more of the placement themselves.
They are a wearing part on a frame that gets used daily, so keeping a spare set on hand is reasonable for a school or a therapy service.
