title: Physical Activity Inventory for Patients with Spinal Cord Injury.
abstract: OBJECTIVE
  To test the reliability and validity of a physical activity instrument adapted for individuals with spinal cord injuries (SCI), thePhysical Activity Instrument-SCI (PAI-SCI).
  
  
  METHODS
  Eligible participants completed the adaptedPAI-SCIquestionnaire at baseline and 1 week later. At baseline, they were also given an Actical accelerometer to wear on their wrist for 1 week.
  
  
  RESULTS
  Forty-three male subjects completed the study. There was a moderate relationship between total score on thePAI-SCIand total activity count determined by accelerometry (r = 0.42, P = 0.036). ThePAI-SCIwas able to differentiate between people with upper and lower level injuries (P = 0.05). Test-retest reliability was supported for the exercise and the general activity/self care subscales and not supported for the light household or the outdoor/gardening subscales.
  
  
  CONCLUSIONS
  ThePAI-SCIwas able to distinguish between physical activity amongst those with upper level and lower level injuries. More research is needed before thePAI-SCIcan be recommended for use in clinical trials.
