  1. BMI = body mass index.
  2. VPT = vibration perception threshold at distal pad of halluces; 0-50V scale with higher numbers indicating poorer sensation and lower numbers indicating better sensation and normal being between 0-15V.
  3. MBQ = Modified Baecke Questionnaire; 3-15 point scale with higher numbers indicating higher self-reported activity levels and lower numbers indicating lower self-reported activity levels.
  4. PF = plantar flexion.
  5. DF = dorsiflexion.
  6. SLR = straight leg raise.
  7. * = statistically significant difference between groups.
  8. † = statistically significant correlation coefficient (r).
  9. Alpha set at 0.05.
