RESUMO

The objective of this research was to evaluate cardio-respiratory responses (heart rate, blood pressure, VO IND.2 , VCO IND.2 e Ve) to neuromuscular electrical stimulation (NMES) of the quadriceps in patients with spinal cord injury. Ten patients (five paraplegics and five tetraplegics) and one healthy subject participated in this study. The protocol of the test consisted of ten minutes of rest, twenty minutes of NMES of the quadriceps and ten minutes of recovery. However, the healthy subject performed the voluntary movement of knee flexion and extension. The findings in this study indicated that patients during NMES demostrated low values of VO IND.2 e VCO IND.2 , slow gas kinetics and altered values of P IND.O2 and P IND.CO2 , on the others cases, the fast kinetics of the gas was verified. Moreover, there were increases in blood pressure and heart rate. Nevertheless, for some patients, heart rate response limitations were observed. Therefore, the patients presented some limitations in the cardio-respiratory responses, indicating performance of exhaustive exercise, but the use of NMES can elicit improvements in exercise tolerance due to its benefits
