  1. 1 Data are mean (S.D.), and differences between groups were analysed using independent samples t-tests.
  2. 2 Data are median (interquartile range), and differences between the groups were analysed using Mann Whitney U-tests. Occupational rating scale subscales can range from 0 (lowest level of lower limb stress) to 10 (highest level of lower limb stress).
