title: Effect of exercise on calf muscle pump function in patients with chronic venous disease.
abstract: BACKGROUND
  Musculoskeletal dysfunction may be associated with poor calf muscle pump function in patients with chronic venous ulceration. The aim of this study was to evaluate the effects of physical exercise on calf muscle pump function.
  
  
  METHODS
  Twenty patients were recruited into a 6-week intensive exercise programme. Calf muscle function and calf muscle pump function were assessed using an isokinetic device and air plethysmography respectively, before and after the exercise programme.
  
  
  RESULTS
  There was significant improvement in calf muscle pump function, measured as increased ejection fraction and decreased residual fraction (P < 0.05); however, venous reflux was not altered (P > 0.05). Calf muscle strength and endurance parameters all increased, but not significantly (P > 0.05).
  
  
  CONCLUSIONS
  Poor calf muscle pump function in patients with chronic venous ulceration can be improved by physical exercise.
