Table 2 Subject baseline characteristics, mean within-group change following intervention with brace and in controls (without brace), and between-group differences in change (pre- and post-intervention)

From: With a biomechanical treatment in knee osteoarthritis, less knee pain did not correlate with synovitis reduction

  1. aNumber of observations for KOOS and VASNA are less than the number attending week 6 visit due to incomplete questionnaires. bDynamic data model error prevented the use of one RElate observation
  2. The reduction in RER represents a reduction in the rate of enhancement and was seen significantly more often in the control group, not in the treatment group
