Split posterior tibial-tendon transfer in spastic cerebral palsy.

Sixteen split posterior tibial-tendon transfers, usually with heel-cord lengthening, were performed on sixteen children with spastic cerebral palsy and equinovarus deformities. The patients were followed for a minimum of two years postoperatively. All of the varus deformities were corrected, although two patients required an osteotomy of the calcaneus because of fixed varus deformity. There were no recurrences of the varus deformities, nor were any valgus or calcaneal deformities produced, and the equinus element of the gait was eliminated.

Variability of electromyographic patterns for level-surface walking through a range of self-selected speeds.

The surface electromyographic patterns of eight muscles and the foot-contact patterns exhibited by 25 normal persons between the ages of 20 and 40, were measured and studied. These persons were walking indoors on a level surface without shoes at several different self-selected walking speeds. The electromyographic patterns demonstrated a considerable amount of interindividual variability at each speed. There were definite trends in the number of individuals exhibiting each pattern type as walking speed increased. The foot-contact patterns showed a consistent sequencing of foot events at all speeds with the double-limb support stages and stance phase comprising a smaller percentage of the gait cycle as speed increased.

Habitual toe-walkers. A clinical and electromyographic gait analysis.

Six children who were habitual toe-walkers were studied using electromyographic techniques. In the initial gait evaluation, the muscle synergy pattern was found to be abnormal during the toe-toe gait as well as during the heel-toe gait. After treatment with casts, each patient had a normal electromyographic pattern during heel-toe gait.
