Abstract
A reciprocating gait orthosis or prosthesis to provide a natural and efficient method of ambulation for paraplegic patients comprises hip joints which are coupled by a single push/pull member in the form of an inner metal cable which is surrounded by two nylon tubes, the outer nylon tube being a tight fit on the inner nylon tube which, in turn, closely embraces the inner metal cable so that they all move together, the arrangement also comprising two limb members each having a respective hip joint at one end and a respective knee joint at the other end with the joints rotatably coupling the limb member to further members which are pivotally coupled to a tie rod whereby rotation of the further members relative to the limb member about the joints is coordinated by the tie rod, there also being a spring which acts to urge the arrangement into a standing position and controls movement into a sitting position.
