Artificial Hands Patients with limited hand function due to various medical conditions such as hand injuries, strokes, or spinal cord injuries (SCI) which often result in hand paralysis need artificial hands. Types of Artificial Hands Body-Powered Artificial Hands : Controlled by cables linked to a harness worn on the opposite shoulder of the amputated limb. Movement is driven by the user's shoulder and upper arm muscles. Limitations: Limited range of motion due to potential derailment of the cable system. Myoelectric Artificial Hands : Use electromyography (EMG) sensors placed on the skin over residual limb muscles. Detects electrical signals from muscle contractions, which are then processed to control hand movements. Limitations: Expensive, requires regular maintenance, sensitive to sweat and moisture affecting sensor performance. C
