FreeGait Stance-Control KAFO

Locked-knee gait costs patients energy with every circumducted step. The FreeGait's stance-control knee joint engages resistance only when the limb is loaded, then releases automatically into free swing — preserving knee flexion during swing phase and cutting the compensatory hip-hike that drives long-term back pain in lifetime KAFO users.

The mechanical joint requires no batteries or electronics and cycles reliably across cadence changes, ramps, and uneven ground. Custom fabrication pairs the joint with carbon-reinforced thermoplastic shells to keep total device weight down; candidates should present with adequate hip flexor power and a passively correctable knee.
