  1. Values represent mean Z-scores +/- SD, asterisk represents p<0.05 compared to controls.
  2. Tibial data for paraplegics and tetraplegics (n=19), radial data for tetraplegics only (n=10)
  3. vBMD - volumetric bone mineral density, CSA - cross sectional area, BMC - bone mineral content,
  4. pSSI – polar strength-strain index
