Figure 1 The Centre of Mass trajectory during the Five Times Sit-to-Stand test. A) The CoM trajectory in the medial-lateral dimension of one individual reporting high perceived pain, indicating a strategy to reduce pain. B) The CoM trajectory in the A/P dimension of one individual performing the 5STS relatively slow and reporting low perceived pain, indicating a strategy to reduce required muscle strength.
