Tibion has just introduced its PK100 Bionic Leg Orthosis at the American Physical Therapy Association's Combined Sections Meeting. The Bionic Leg is an intelligent, wearable, power-assist device for the leg, which actively supplements muscle strength to enhance rehabilitation therapy. Tibions PK100 Bionic Leg Orthosis detects user actions such as sitting, standing, walking and ascending/descending stairs. PK100 Bionic Leg Orthosis sounds like a good idea to regain one's mobility along with a sense of independence and freedom. We still don't know how much it will cost and when it will be available commercially.
