OBJECTIVES: To compare the effects of adding electrical dry needling into a manual therapy and exercise program on pain, stiffness, function, and disability in individuals with painful knee osteoarthritis (OA).
METHODS: Two hundred and forty-two participants (n=242) with painful knee OA were randomized to receive 6 weeks of electrical dry needling, manual therapy and exercise (n=121) or manual therapy and exercise (n=121). The primary outcome was related-disability as assessed by the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index at 3 months.
RESULTS: Individuals receiving the combination of electrical dry needling, manual therapy and exercise experienced significantly greater improvements in related-disability (WOMAC: F=35.504; P<0.001) than those receiving manual therapy and exercise alone at 6 weeks and 3 months. Patients receiving electrical dry needling were 1.7 times more likely to have completely stopped taking medication for their pain at 3 months than individuals receiving manual therapy and exercise (OR: 1.6; 95%CI: 1.24-2.01; P=0.001). Based on the cutoff score of +5 on the Global Rating of Change (GROC), significantly (X =14.887; P0.82) for all outcome measures in favor of the electrical dry needling group at 3 months.
DISCUSSION: The inclusion of electrical dry needling into a manual therapy and exercise program was more effective for improving pain, function and related-disability than the application of manual therapy and exercise alone in individuals with painful knee OA.
