기능적 전기 자극: Part Ⅱ

Functional Electrical Stimulation: Part II

When applying FES to patients, proper evaluation must be performed prior to treating patient. Patients with thoracic lesions between T4~T12 are suitable for FES. However, these patients must have excitability of the leg muscles. Thus, excitability testing is an essential part of the screening program(stimulation at 80V gives a response). Before standing or walking is attempted the patients must perform restrengthening exercise, so that the quadriceps muscle group minimum strength is 40 Nm (corresponding to a manual grade of F+ to G). After that walking and standing can be attempted. The effects of FES are as follows: prevents pressure sores; development and maintenance of muscle properties; prevents disuse atrophy and contractures.
