A walking assist device, which is to be worn on a person’s leg, includes a shank link, a thigh member, and a knee mechanism. The thigh member is in contact with the person’s thigh when the device is worn on the person’s leg. The knee mechanism rotatably connects the shank link to the thigh member. When the shank link is in contact with the ground, the knee mechanism is configured to resist the rotation of the shank link relative to the thigh member to prevent the person’s foot from contacting the ground and reduces ground reaction forces entering the person’s foot.

A semi-actuated above knee prosthetic system (100), includes a shank link (105) coupled to an artificial foot (108), a knee mechanism (107) connected to the shank link (105) and a thigh link (103) attached to an above-knee remaining lower limb (110) of an amputee, is operable in two modes controlled by a signal processor (130) linked to various sensors (120,122,124,126,127). In the actuated mode, power is delivered to a torque generator (104) connected to the knee mechanism (107) to move thigh (103) and shank links (105). In the un-actuated mode, a control circuit (204) operates in a non-powered manner with modulated resistance in the knee mechanism (107). Power is delivered through an electric motor (202) connected to a battery source (205) and employed to drive a hydraulic pump (201) as part of an overall hydraulic power unit (200) including the torque generator (104).
