description Semi-passive control system (10) comprises a pneumatic spring actuator (16), a pressure regulator (22) in communication with the pneumatic spring actuator (16), a hydraulic locking actuator (18), a hydraulic valve (20) in communication with actuator (18), a power source (14), a pulley wheel (42), and a cable (46) having a first end in contact with pulley wheel (42), first and second side portions (50, 56) extending from opposing sides of pulley wheel (42), and a second end adapted to connect to an orthosis device (76). At least one cable clamp (62) attaches to second side portion (56) of cable (46) and interconnects cable (46) to shafts (112b, 118b) of actuators (16, 18). A central control unit (12) includes a processor (13a) and a computer readable storage medium (13b) having program instructions stored thereon for execution by the central control unit to adjust stiffness, damping or stiffness and damping parameters.
