Abstract
Exercise orthoses are described that include a frame, a fluid bladder held by the frame, a pressure sensor attached to the fluid bladder and a microprocessor receiving the pressure measurements. The microprocessor monitors variations in pressure and determines differences between the measured pressures and predetermined target values. The frame can be designed to support a hinge joint or at least one vertebra. Furthermore, corrective back orthoses are described that include a frame, force applicators connected to the frame to apply force to the patient's spine, a sensor that measures forces associated with the force applicators and a control unit that monitors forces measured by the sensor. The corrective back orthosis can include fluid bladders as force applicators. The control unit can include a microprocessor.
