Brief Summary:
Skeletal muscle atrophy is associated with catabolic conditions such as major surgical interventions and leads to reduced muscle strength, increased clinical complications and prolonged convalescence. Several studies revealed immobilisation as a major stimulus for muscle wasting in severely ill patients. This study investigates the potency of neuromuscular electrical stimulation on skeletal muscle growth factors and degradation processes in major abdominal surgery patients.

Condition or disease Intervention/treatment Phase
Muscular Atrophy Device: neuromuscular electrical stimulation: Cefar-Sport (CefarCompex Scandinavia AB) Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 26 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Investigator)
Primary Purpose: Basic Science
Official Title: The Effect of Neuromuscular Electrical Stimulation on Muscle Metabolism of Major Abdominal Surgical Patients
Study Start Date : December 2005

Arm Intervention/treatment
Active Comparator: A Device: neuromuscular electrical stimulation: Cefar-Sport (CefarCompex Scandinavia AB)
Electrical stimuli of 50 Hz (pulse width 0.25ms, 8 sec on, 4 sec off) were applied daily for 30 min, for 4 days, starting on the first postoperative day.The amplitude of the electrical stimuli in the stimulated leg was adjusted to ensure maximum tolerable muscle contraction.
Sham Comparator: B Device: neuromuscular electrical stimulation: Cefar-Sport (CefarCompex Scandinavia AB)
Electrical stimuli of 50 Hz (pulse width 0.25ms, 8 sec on, 4 sec off) were applied daily for 30 min, for 4 days, starting on the first postoperative day. Current was increased until the patient could feel a tingling sensation but no muscle contraction was visible or palpable.



Primary Outcome Measures :
  1. mRNA level of IGF-1Ea

Secondary Outcome Measures :
  1. mRNA level of MGF, total RNA content, total protein content, ubiquitin conjugated proteins, proteasome activity
