Study Summary

Fifty-nine patients with knee osteoarthritis were randomized to receive either static stretching exercises (n=29) or heel kicking exercise (HKE) (n=30). Both groups also received traditional Chinese medicine hot compresses, celecoxib, and quadriceps contraction exercises. The primary outcome was change in knee pain and stiffness measured by the WOMAC index. Secondary outcomes included knee range of motion, Five-Times-Sit-to-Stand Test (FTSST), Timed Up and Go Test (TUG), Six-Minute Walk Test (6MWT), and patient satisfaction. Outcomes were assessed before treatment and after 2 weeks. Overall, the results of the study revealed significantly greater improvements in pain, stiffness, mobility, and satisfaction in the HKE group compared to controls. These findings suggest that HKE is a safe and effective dynamic stretching method that may offer superior short-term outcomes in KOA rehabilitation.
