Acupuncture may be helpful for treating tendinitis. A controlled trial compared acupuncture to sham (fake) acupuncture in people with shoulder tendinitis and found that acupuncture treatment produced significantly higher scores on a combined measurement of pain, ability to perform daily activities, ability to move shoulder without pain, and strength.⁷ This study also reported that the beneficial effects of acupuncture continued for at least three months following treatment. Another controlled study found traditional “deep” acupuncture more effective than superficial acupuncture for tennis elbow immediately after a series of ten treatments, but at 3 to 12 months’ follow up, both treatment groups had improved similarly.⁸ A third controlled study found no benefit from ten treatments of laser acupuncture for tennis elbow.⁹

Certain treatments used by physicians and other healthcare practitioners have been shown to be effective for tendinitis. In a controlled trial, patients with tendinitis of the shoulder received 24 treatments over six weeks of either ultrasound or a sham treatment.¹⁰ Ultrasound resulted in considerable improvement in pain level and overall quality of life, but many of the patients had their original symptoms return after nine months. The use of ultrasound for tennis elbow has not been validated, according to a systematic review of controlled studies.¹¹ One controlled trial compared the effects of ultrasound alone to ultrasound plus a topical steroid medication (a process known as phonophoresis, where ultrasound is used to drive a substance into the skin).¹² Both of these treatments were given three times per week for three weeks and both produced similar reductions in pain and tenderness.

Preliminary studies have suggested that daily use of TENS (transcutaneous electrical nerve stimulation) for one to two weeks reduces or eliminates pain in patients with tendinitis.^{13, 14} Controlled studies are needed to confirm these findings.
