Table 3 Effect of intervention: differences within the groups

From: Functional consultation and exercises improve grip strength in osteoarthritis of the hand – a randomised controlled trial

  Combined intervention difference (FU - BL) (mean (SD)) RC difference (FU - BL) (mean (SD)) p value
Grip strength (Vigorimeter), dominant hand, bar 0.03 (0.11) −0.03 (0.13) 0.001
Grip strength (Vigorimeter), non-dominant hand, bar 0.01 (0.10) −0.03 (0.13) 0.002
Self-reported pain on a LSab −1.35 (2.38) −0.88 (2.12) 0.339
Self-reported satisfaction with treatment on a LSab −3.50 (3.37) − 0.92 (2.95) 0.002
