Table 2.

Changes from baseline according to group allocation. Values were calculated on the basis of 51 participants in the control group and 39 in the intervention group at 6 weeks; 55 and 40, respectively, at 3 months; and 56 and 38 at 12 months. Change data presented as unadjusted mean change scores, relative to baseline (SD); positive change scores represent improvement for the AQoL and heiQ instruments and negative change scores represent improvement for the WOMAC, K10, and MAPT.
