title: Testosterone replacement therapy and motor function in men with spinal cord injury: a retrospective analysis.
abstract: OBJECTIVE
  To evaluate motor function in men with spinal cord injury (SCI) given testosterone replacement therapy (TRT).
  
  
  METHODS
  American Spinal Injury Association (ASIA) rehabilitation discharge motor index scores were compared between men with SCI given TRT (testosterone cypionate, 200 mg, monthly; n = 50) and a comparison group (n = 480) in a retrospective study. Covariates included admission motor and FIM scores, level of injury (paraplegia/tetraplegia), days since injury, and age.
  
  
  RESULTS
  ASIA discharge motor scores for ASIA impairment scale grades C and D were significantly different (P < 0.05) in men with incomplete SCI given TRT, relative to the comparison group. The covariate-adjusted mean discharge score for the TRT group was higher than for the comparison group. There were no significant differences in discharge FIM scores (P = 0.34) for men with incomplete injuries and no differences in the adjusted discharge ASIA motor scores (P = 0.92) or adjusted discharge FIM scores (P = 0.16) for men with complete injuries.
  
  
  CONCLUSIONS
  The data support a relationship between TRT and strength gains in men with residual motor function after SCI. Prospective studies are necessary to validate these findings.
