Abstract

OBJECTIVE

To study effects of surface electric stimulation of the gluteal muscles on the interface pressure in seated persons with spinal cord injury (SCI).

DESIGN

One session in which alternating and simultaneous surface electric stimulation protocols were applied in random order.

SETTING

Research laboratory of a rehabilitation center.

PARTICIPANTS

Thirteen subjects with SCI.

INTERVENTION

Surface electric stimulation of the gluteal muscles.

MAIN OUTCOME MEASURES

Interface pressure, maximum pressure, pressure spread, and pressure gradient for the stimulation measurement. Variables were compared using 2-tailed paired t tests.

RESULTS

Alternating and simultaneous stimulation protocol caused a significant (P<.01) decrease in interface pressure (-17+/-12 mmHg, -19+/-14 mmHg) and pressure gradient (-12+/-11 mmHg, -14+/-12 mmHg) during stimulation periods compared with rest periods. There was no significant difference in effects between the 2 protocols.

CONCLUSIONS

Surface electric stimulation of the gluteal muscles in persons with SCI causes a decrease in interface pressure. This might restore blood flow in compressed tissue and help prevent pressure ulcers.
