fall) and Period as factors showed a marginally significant interaction ( F 1,81 = 3.82, P = 0.054), and a significant difference between the two periods for the CD group (NK, P = 0.016) but not for the fall prevention group (NK, P = 0.769).
Interaction and post hoc tests failed to reach statistical significance when comparing CD to either fall prevention ( F 1,54 = 1.06, P = 0.308) or Tai Chi Chuan ( F < 1).
