Which therapy applies electricity at specific locations to stimulate nerves and muscles?

The therapy that applies electricity at specific locations to stimulate nerves and muscles is electrical stimulation. This method is widely utilized in physical therapy to promote healing, reduce pain, and improve muscle function. Electrical stimulation works by delivering controlled electrical impulses through electrodes placed on the skin, which can lead to muscle contractions or changes in pain perception. This technique is effective in various rehabilitation contexts, helping patients regain strength and functionality after injuries or surgeries.

While other therapies like therapeutic ultrasound and TENS also use electrical principles, they serve different purposes. Therapeutic ultrasound uses sound waves rather than electrical impulses to address tissue healing and inflammation. TENS specifically focuses on pain relief through electrical stimulation, but it operates at a different intensity and mechanism to primarily target nerve pathways for pain management rather than overall muscle stimulation. Biofeedback therapy, on the other hand, is a process that teaches individuals to control physiological processes by providing real-time data on bodily functions, which is not rooted in direct electrical stimulation of muscles. Thus, the characteristics and applications of electrical stimulation make it the correct therapy related to your question.
