We intend to apply functional electrical stimulation (FES) instead of orthoses to conditions such as hemiplegic cerebral palsy children. The purpose of this paper is to report on application of FES to the hemiplegic cerebral palsy children. The subjects were two boys (both are 6years-old) and a 7 year-old girl. They were diagnosed as spastic hemiplegic cerebral palsy. Heel contacts were not see...

Traction injury to the sciatic nerve can occur during hamstring lengthening. The aim of this study was to monitor the influence of hamstring lengthening on conduction in the sciatic nerve using evoked electromyography (EMG). Ten children with spastic cerebral palsy underwent bilateral distal hamstring lengthening. Before lengthening, the evoked potential was recorded with the patient prone. Dur...

Background and purpose - Femoral lengthening may result in decrease in knee range of motion (ROM) and quadriceps and hamstring muscle weakness. We evaluated preoperative and postoperative knee ROM, hamstring muscle strength, and quadriceps muscle strength in a diverse group of patients undergoing femoral lengthening. We hypothesized that lengthening would not result in a significant change in k...

Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the musclesduring corticotomy and their stretching during distraction play a crucial role in occurrence of complications and finallimb function. We present here a systematic codified nomenclature system of each muscle summarising all theinfluence that corticotomy and distraction have the part...

A number of studies over the last few decades have established that the control strategy employed by the nervous system during lengthening (eccentric) differs from those used during shortening (concentric) and isometric contractions. The purpose of this review is to summarize current knowledge on the neural control of lengthening contractions. After a brief discussion of methodological issues t...

Knee anomalies are common in patients with congenital short femurs who require lengthening to correct limb-length discrepancies. We retrospectively reviewed the incidence of knee arthritis and the factors influencing its occurrence after femoral lengthening using the Wagner method. Twenty-three patients with congenital short femurs treated with the Wagner method were followed up until skeletal ...
