One of the most important factors in the rehabilitation of the amputee is the preparation of the patient and stump for limb fitting and training. The different procedures for the upper and lower extremities are described. Emphasis is laid on the importance of early reassurance and rehabilitation whenever possible. Patients unavoidably immobilised for long periods require general physical reconditioning before limb fitting and training can be undertaken. Special care is needed to avoid the upper limb amputee's becoming dependent on the surviving hand and using the artificial limb only for its cosmetic effect.
