 Shoulder pain felt when performing daily activities is a common complaint at all ages. Shoulder impingement syndrome is one of the most common causes of shoulder pain. Since this disease is relatively prevalent, there is an urgent need to develop a treatment method with fewer complications. Magnet therapy (MT) is one of the therapies that has been recently used to treat various musculoskeletal disorders.

 This study aimed to evaluate the effects of MT on pain and disability in patients with shoulder impingement syndrome.

 In this double-blind clinical trial study, 60 patients diagnosed with shoulder impingement syndrome were randomly assigned to three groups including the "MT 18 Hz" group, the "MT 100 Hz" group, and the "Sham" group. All patients received Magnet therapy three times a week for four weeks in addition to routine treatment. In the sham group, Magnet therapy was used as a placebo. All three groups received routine electrotherapy and exercise therapy. Before and after the treatment, the pain level was evaluated by the NRS scale, the disability level was assessed by the Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH), and the range of motion of the shoulder was measured using a goniometer. The values obtained in the groups and for the groups were compared before and after the treatment.

 The intragroup comparison of the three groups revealed a statistically significant improvement in all variables (including NRS score, DASH, and shoulder range of motion) (P < 0.05). The intergroup comparison, on the other hand, showed no statistically significant difference for any of the variables (P > 0.05).

 It was concluded that routine physiotherapy significantly reduced pain and disability as well as improved shoulder range of motions in patients with shoulder impingement syndrome. Moreover, using magnet therapy with two frequencies of 18 and 100 Hz along with the routine electrotherapy and exercise therapy had no additional positive effect on the recovery process of patients with shoulder impingement syndrome.

Magnet therapy has been used increasingly as a new method to alleviate pain. Magnetic products are marketed with claims of effectiveness for reducing pain of various origins. However, there are inconsistent results from a limited number of randomized controlled trials (RCTs) testing the analgesic efficacy of magnet therapy. This study aimed to evaluate the safety and effectiveness of magnet therapy on reliving various types of pain.
A systematic search of two main medical databases (Cochrane Library and Ovid Medline) was conducted from 1946 to May 2014. Only English systematic reviews that compared magnet therapy with other conventional treatments in patients with local pain in terms of pain relieving measures were included. The results of the included studies were thematically synthesized.
Eight studies were included. Magnet therapy could be used to alleviate pain of various origins including pain in various organs, arthritis, myofascial muscle pain, lower limb muscle cramps, carpal tunnel syndrome and pelvic pain. Results showed that the effectiveness of magnetic therapy was only approved in muscle pains, but its effectiveness in other indications and its application as a complementary treatment have not been established.
According to the results, it seems that magnet therapy could not be an effective treatment for relieving different types of pain. Our results highlighted the need for further investigations to be done in order to support any recommendations about this technology.
