Abstract

[Purpose] This study examined the immediate effects of transcutaneous electrical nerve stimulation on a six-minute walking test, Borg scale questionnaire and hemodynamic responses in patients with chronic heart failure. [Subjects and Methods] Thirty patients with stable systolic chronic heart failure came to the pathophysiology laboratory three times. The tests were randomly performed in three sessions. In one session, current was applied to the quadriceps muscles of both extremities for 30 minutes and a six-minute walking test was performed immediately afterward. In another session, the same procedure was followed except that the current intensity was set to zero. In the third session, the patients walked for six minutes without application of a current. The distance covered in each session was measured. At the end of each session, the subjects completed a Borg scale questionnaire. [Results] The mean distance traveled in the six-minute walking test and the mean score of the Borg scale questionnaire were significantly different across sessions. The mean systolic and diastolic pressures showed no significant differences across sessions. [Conclusion] The increase in distance traveled during the six-minute walking test and decrease in fatigue after the use of current may be due to a decrease in sympathetic overactivity and an increase in peripheral and muscular microcirculation in these patients.
