title: Electrical stimulation and treadmill gait in tetraplegic patients: assessment of its effects on the knee with magnetic resonance imaging.
abstract: METHODS
  Evaluation of knees of tetraplegic patients who have been walking for several months with the aid of a system that involves neuromuscular stimulation, treadmill and a harness support device.
  
  
  OBJECTIVE
  To investigate if the training program could cause knee injury to tetraplegic patients.
  
  
  METHODS
  Hospital das Clinicas - UNICAMP. Campinas-SP, Brazil.
  
  
  METHODS
  Nine patients were evaluated. Clinical exam and magnetic resonance images (MRIs) were used for evaluation. MRIs were taken before and after the training program, in a 6-month interval for each patient. There were two sessions of training every week. Each session lasted 20 min.
  
  
  RESULTS
  No severe clinical abnormality was observed in any patient. Mild knee injury was observed in four of nine patients studied.
  
  
  CONCLUSIONS
  Tetraplegic patients undergoing treadmill gait training deserve a close follow-up to prevent knee injury.
