Physical Agents & Electrotherapeutic Modalities
We cannot recommend for or against the use of iontophoresis, phonophoresis, transcutaneous Electical Nerive Stimulation (TENS), ice, heat, massage, or activity modification for patients who have rotator cuff related symptoms in the absence of a full thickness tear.

Rationale
There were no studies identified examining iontophoresis, phonophoresis, TENS (transcutaneous electrical nerve stimulation), ice, heat, or massage as non-operative treatments in patients with rotator cuff-related symptoms.
