Cinematographic analysis of the gait of lame horses

Summary The gait characteristics of a horse with a non-articular fracture of the right supraglenoid tubercle are described. On physical examination, protraction of the injured limb was painful and limited in extent. Observation at the trot indicated that the horse was transferring weight onto the sound (left) diagonal by lowering the head, neck and trunk during the diagonal stance phase. There was little angular rotation of the shoulder and elbow joints present in the injured limb and consequently the toe barely cleared the ground during the swing phase. Analysis of high speed cinematography films was used to measure the stride parameters and quantify the gait asymmetries. The stance phase and the anterior phaseof the stride were significantly shorter in the right forelimb than the left (p
