Ultrasound combined with neuromuscular electrical stimulation (NMES) can be more effective than either treatment alone in reducing pain and improving joint function: 

Pain and lumbar dysfunction

• A study found that ultrasound combined with NMES was more effective than either treatment alone in reducing pain and lumbar dysfunction in patients. 

Less Complications

• Another study found that patients who received ultrasound combined with NMES had the lowest incidence of complications, such as low back pain, sciatica, and intermittent claudication. 

Osteoarthritis

• Studies have shown that ultrasound combined with NMES can effectively relieve pain and improve joint function in patients with osteoarthritis. 

Fibromyalgia

• A study found that combining ultrasound and electrical stimulations improved range of motion and reduced discomfort in people with fibromyalgia.

NMES can also be used to increase muscle strength and endurance, and make muscles bigger.
