F56

These Athletes will have normal arm and trunk muscle power. They will have hip flexor and hip adductor muscle activity, knee extensor muscle activity, and up to grade 3 power in the medial hamstrings (knee flexor). Usually have normal trunk control in the upwards, backwards and forwards, and rotation movements. May use hip flexors to reinforce forward movement in the process of throwing. Trunk rotation is best seen in the discus event. Equivalent activity limitation to Athlete with bilateral high above knee amputation or complete spinal cord lesion at L2-4. Athletes with a complete spinal cord injury must have grade 0 for hip extension and for hip abduction. Unilateral hip disarticulation or very short femur is also described. Those Athletes with incomplete spinal cord injuries who have grade 1s and 2s in most muscle groups in the lower limbs will generally fit into the F56 class.
