Hello All and Happy New Year,
I am working with an avid bicycler who is having difficulty un-clicking his transtibial foot from his clip-less pedal. The motion required is a rapid twist of the foot moving the heel away from mid-line while weight bearing on the ball of the foot.
He is currently in a TSB socket w/expulsion valve, gel knee sleeve and CPI Trustep. The combo between available ML foot motion and slight residual limb transverse motion (due to only partial wt bearing during task) does not provide enough rotational force to disengage the bicycle shoe from the pedal.
I have suggested using a pedal clip on the prosthetic side, but this fella is former competitor racer and won't hear of it! Suggestions? Foot choice? He does not tolerate locking pin & PTB socket design...thought better purchase on the tibia would create enough force...not. Must we go w/a thigh component and use joints to provide enough rigidity? How would that play out with century rides (100 miles)?
As always, you thoughts are greatly appreciated.
