Abstract

Detailed knowledge on normal and pathological joint motion during physiological activities such as gait is necessary both for planning and evaluating of orthopaedic surgery in pyramidal-extrapyramidal disorders of movement. A methodology of stereometric gait evaluation using cinephotography in three planes combined with a pair of transparent force plates and electro-myographic recording is described. Resultats of a foot load study in 35 normal preschool children and long them follow-up evaluations on hip and knee joint operations in cerebral spastic patients are demonstrated. Problems of picture analysis are discussed. As a mean for improvement in surgical procedures for such patients, detailed information are obtainable by cinephotography is mandatory. In addition, three-dimensional motions in large joints such as hips, knees and talo-crural articulations must be measured quantitatively with a high degree of accuracy. Special polyhedral reflective targets were developed to permit semiautomatic and automatic image analysis for joint range measurement in the lower extremities.
