Fillauer (Motion Control) · Wrists · PR-063
The Fillauer ProWrist Rotator is a powered wrist rotator from the Motion Control line that sits inside the forearm of a myoelectric prosthesis. It ships with a 4-band coaxial plug as standard, or in 6-band sequential and simultaneous builds that pair with TASKA and PSYONIC hands. Setup runs through an iOS interface only, and the unit uses common 3-pin electrode cables and a 2-pin battery cable.
Suits people who control a myoelectric hand and want the wrist to turn under power as well. It can be combined with a hybrid elbow in above-elbow builds. Your prosthetist chooses the band version and laminates the unit into the forearm.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
