Acupressure works … oh no, it doesn't !!!
This double-blind RCT aimed to test the efficacy of self-administered acupressure for pain and physical function in adults with knee osteoarthritis (KOA). 150 patients with symptomatic KOA participated and were randomized to verum acupressure, sham acupressure, or usual care. Verum and sham, but not usual care, participants were taught to self-apply acupressure once daily, five days/week for eight weeks. Assessments were collected at baseline, 4 and 8 weeks. The numeric rating scale (NRS) for pain was administered during weekly phone calls. Outcomes included the WOMAC pain subscale (primary), the NRS and physical function measures (secondary). Linear mixed regression was conducted to test between group differences in mean changes from baseline for the outcomes at eight weeks. Compared with usual care, both verum and sham participants experienced significant improvements in WOMAC pain, NRS pain and WOMAC function at 8 weeks. There were no significant differences between verum and sham
