BMI = body mass index.

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.

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.

PF = plantar flexion.

DF = dorsiflexion.

SLR = straight leg raise.

* = statistically significant difference between groups.

† = statistically significant correlation coefficient (r).

Alpha set at 0.05.
