  1. Abbreviations: ST, sling exercise training group; CPM, continuous passive motion group; n/a, not available.
  2. ANCOVA: pain was adjusted for sex, weight, age and physical activity; length of hospital stay was adjusted for sex, weight, age, pain and physical activity; the posttest-values of physical activity were adjusted for sex, weight, age and the follow-up-values were adjusted for sex, weight and age.
  3. Values are presented as estimated marginal means (standard deviation).
