RESUMO

Electromyography biofeedback is a learning technique for voluntary control of physiological responses through operant conditioning. The electromyographic signals from the quadriceps muscles of two biofeedback series were compared using the Brucker method, with a 50-minute weekly session during four weeks and a three-month interval, in 20 patients with cervical spinal cord injury, in the sitting position and during the transition from the sitting to the orthostatic position. An increase in the amplitude of the electromyographic potential was shown in the second series. It was proven that during the transition from the sitting to the orthostatic position it is possible to gather a larger number of fibers of the quadriceps as compared to the sitting position
