Electronically Controlled Hydraulic Transfemoral Prosthesis (K-Leg V2)

K-Leg V2 is an electronically controlled hydraulic transfemoral prosthesis designed for people with transfemoral amputation. Load and knee-angle sensors detect gait conditions in real time, while a microprocessor automatically adjusts hydraulic resistance to support stable walking on level ground, slopes, and stairs. It also incorporates a stumble-recovery function to control knee flexion and improve stability when a risk of falling is detected.
