The study conducted a comparative assessment of the effectiveness of physical exercises on the quadriceps femoris muscle and electrical stimulation with sinusoidal modulated currents of this muscle in patients with knee osteoarthritis. Both methods demonstrated high efficacy and contributed to the improvement of functional parameters of the quadriceps femoris muscle. After therapy using this technology, a statistically significant reduction in clinical manifestations of the disease and an improvement in the general well-being of patients were observed.
