title: The influence of orthotic gait training with an isocentric reciprocating gait orthosis on the walking ability of paraplegic patients: a pilot study.
abstract: OBJECTIVE
  The aim of this study was to evaluate the influence of walking with an isocentric reciprocating gait orthosis (IRGO) by spinal cord injury (SCI) patients on walking speed, distance walked and energy consumption whilst participating in a 12-week gait re-training program.
  
  
  METHODS
  Six people with motor complete SCI (mean age 29 years, weight 63 kg and height 160 cm with injury levels ranging from T8 to T12) participated in this study. Gait evaluation was performed at baseline and after 4, 8 and 12 weeks. Walking speed and heart rate were measured to calculate the resulting physiological cost index (PCI).
  
  
  RESULTS
  Reductions in energy consumption were observed after 4, 8 and 12 weeks compared with baseline but were not significant. However, walking distance increased significantly (P=0.010, P=0.003 and P=0.005, respectively) and also did so during the 8-12-week period (P=0.013). Walking speed also improved, but not significantly.
  
  
  CONCLUSIONS
  Intensive gait training with the IRGO improved walking speed and the distance walked by paraplegics, as well as reducing the PCI of walking, as compared with baseline during the whole 12-week period. This indicates that further improvements in these parameters may be expected when utilizing gait training longer than 8 weeks.
