Inhibitive casting of the upper limb was used in the rehabilitation of an eight-year-old girl who sustained a severe closed head injury. The procedure involved concurrent casting of both upper and lower limbs on the left. The wrist and fingers of the right hand were also casted during the initial program. The casting of the upper limbs proved to be a major factor in the subsequent reduction of contracture and hypertonicity and in the establishment of normal movement patterns. Furthermore, a widespread effect on muscle tone was noted during the casting procedure.
