Abstract
  • The purpose of this study was to compare the levels of bone mineral density (BMD) of the whole body (WB) and proximal femurs of physically active men with spinal cord injuries (SCI) to nonactive men with spinal cord injuries. Also, the lean muscle mass (LMM) of active men with SCI was compared to the LMM of nonactive men with SCI. In addition, BMD values of the radii of physically active men with SCI were compared to that of able bodied men of the same age. The subjects N. 46 were between the age of 20-55 (μ=37.83 ± 6.63 years), and were at least 2 years post spinal cord injury. Subjects with SCI were matched on similar level of lesion of the spinal cord, age, height, weight, and years post injury for the purpose of analyzing data. There were 14 active men with paraplegia and 14 nonactive men with paraplegia, 9 active men with quadriplegia and 9 nonactive men with quadriplegia. All BMD data was obtained utilizing a Hologic QDR 1000W dual energy x-ray absorptiometer. A two-factor (level by group) analysis of variance revealed no significant difference for all sites (Whole body, Total hip, radii, LMM) comparing the active and nonactive men with SCI. T-scores and z-scores generated from the Ho logic QDR 1000/W were analyzed using two-factor ANOVA (level by group). The active men with paraplegia had significantly higher BMD levels for all sites when compared to the other groups. These values may be explained by the number of incomplete injuries in the experimental group. Subjects in the physically active group did not clearly show a statistically significant difference on any of the dependent measures. However, values for the dependent measures were higher for the physically active group compared to the values of the nonactive group.
