Riassunto dello studio

Sixty patients with bilateral knee osteoarthritis were randomized to receive diadynamic currents combined with exercise (n=30, 60 knees) or exercise alone (n=30, 60 knees), three times a week for 8 weeks. The primary outcomes were changes in knee pain assessed by the visual analog scale and disability measured using the Lequesne Index. Secondary outcomes included mobility (Timed Up and Go test), range of motion (goniometer), muscle strength (dynamometer), pain and disability composite scores (Western Ontario and McMaster Universities Osteoarthritis Questionnaire), and medication intake (paracetamol). Assessments were conducted at baseline, 8 weeks, and 6 months. Overall, the study found that adding diadynamic currents significantly improved pain and disability scores compared to exercise alone, with sustained benefits at 6 months. These findings suggest that diadynamic currents may enhance rehabilitation outcomes in knee osteoarthritis.
