Electrical stimulation (e-stim) involves using electrical impulses to stimulate nerves and muscles. It is commonly used in physical therapy for pain management, muscle rehabilitation, and promoting circulation. The benefits include reducing muscle spasms, improving muscle strength, increasing range of motion, and accelerating recovery from injuries. E-stim can also help with managing chronic pain conditions like arthritis and fibromyalgia, offering a non-invasive alternative to medication. It promotes tissue healing by increasing blood flow and oxygen delivery to the affected area.
