Potentiation of muscle strength by focal vibratory stimulation on quadriceps femoris

Prolonged vibratory stimulation of the quadriceps femoris, both at 80 and at 300 Hz, leads to an increase in muscle strength. The vibration effect does not appear to fade at the end of treatment, but persists at the follow up, suggesting a likely underlying plastic process. The results of the current study suggest that 30-min per day, 5 day focal vibratory treatment can be helpful during the clinical practice to regain muscular strength. It does not require patient's effort during the treatment, requires a little time, its effects are long-lasting, and there are no known adverse effects.
