Tip toe gait is one of the most common abnormalities in cerebral palsy and caused by spasticity in calf muscles or contracture of the triceps surae. The result is clumsy and inefficient. Also, it may wear out shoes too much. Six cerebral palsy patients with tip toe gait were managed by long leg cast. The management had covered a period of 3 to 5 days. The casts provided decreasing of spasticity, increasing of ankle joint range of motion and improving of active ankle dorsiflexion. These results had facilitated the development of the normal gait pattern in these children. Pressure sore had been developed after casting. But it was healed within several days, because it only involved epidermis. Long leg casting was considered as an effective method of the treatment for the tip toe gait caused by cerebral palsy.
