<br/><br/> Purpose: To determine the of effect low frequency neuromuscular stimulation  on ergoreflex activity in advanced heart failure. Methods: Thirty patients of  both sexes (7 women and 23 men) with advanced heart failure were included in  this study with an age range of 50 to 70 years old. Twenty seven of these  patients fully completed the study while three of them died. They were chosen  from outpatient clinic, Eldemerdash hospital, Ain shams university. They were  assigned in a single group which received eight weeks of low frequency  neuromuscular stimulation after thorough assessment of ergoreflex, ejection  fraction and assessment of disability via Minnesota Living with Heart Failure  Questionnaire. Results: Statistical significant alteration of ergoreflex  contribution associated with decreased disability without any statistically  significant changes in ejection fraction. The percentage of change in VE and Vco₂  -37.83% and -36.38% respectively, and in VO₂ by 25.46%.These changes were  associated with improved functional, emotional and psychological status of the  patients with a decline of Minnesota Living with Heart Failure Questionnaire  score by -29.87% without any significant statistical change in ejection fraction  with a change percentage of 2.06%. Conclusion: eight weeks of low frequency  neuromuscular stimulation altered ergoreflex contribution leading to a higher  functional levels without causing any significant central changes regarding  ejection fraction
