Spatial and temporal analysis of walking provides the orthopaedist with objective evidence of functional ability and improvement in a patient. Patients with orthopaedic problems experiencing extreme pain and, consequently, irregularities in joint motions on weightbearing are videorecorded before, during and after a course of rehabilitative treatment and/or surgical correction of their disability. A specially-programmed computer analyzes these tapes for the parameters of walking by locating reflective spots which indicate the centers of the lower limb joints. The following parameters of gait are then generated: dynamic hip, knee and foot angles at various intervals during walking; vertical, horizontal and lateral displacements of each joint at various time intervals; linear and angular velocities of each joint; and the relationships between the joints during various phases of the gait cycle. The systematic sampling and analysis of the videorecordings by computer enable such information to be converted into and presented as computer graphics, as well as organized into tables of gait variables. This format of presentation of the skeletal adjustments involved in normal human motion provides the clinician with a visual format of gait information which objectively illuminates the multifaceted and complex factors involved. This system provides the clinician a method by which to evaluate the success of the regimen in terms of patient comfort and function.
