Who the Proteor Kinterra Hydraulic Ankle/Foot System suits
For community walkers who meet ramps, kerbs and sloping paths daily and want the ankle to adapt at low or moderate intensity. A prosthetist selects the module level and fits the system.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
