Development of digital feedback control is addressed for a series of machines for use by therapists in evaluating and rehabilitating musculoskeletal problems and injuries. These machines, called Isostations, allow movement in three dimensions against graded, controllable resistance generated by forcing fluid through hydraulic servo valves. Design considerations are presented; problem areas are identified; and preliminary valve control simulations are discussed.
