A Longitudinal Study of the Reliability of Acupuncture Deqi Sensations in Knee Osteoarthritis

Changes in KOOS subscale scores from baseline to endpoint. Improvement in each of the 5 domains is indicated by a positive value. (a) The interaction between group (high versus low versus sham) and time (baseline versus endpoint) showed a trend for the KOOS pain subscale (𝐹(2,27)=2.709, 𝑃=.085) but not for either function in daily living (𝐹(2,27)=2.178, 𝑃=.133) or function in sport (𝐹(2,26)=2.047, 𝑃=.149). (b) The interaction between group (real versus sham) and time (baseline versus endpoint) was significant for the KOOS subscale scores for pain (𝐹(1,28)=5.596, 𝑃=.025), function in sport (𝐹(1,27)=4.252, 𝑃=.049), and quality of life (QOL) (𝐹(1,28)=4.682, 𝑃=.039).
