The effect of magnetic field therapy on shoulder pain of patients with subluxation after stroke: Randomized Clinical Trials

Aim and background:

Shoulder pain after stroke is one of the most common types of pain and post-stroke complications, which also reduces the function of the affected hand. Shoulder pain is one of the obstacles to rehabilitation and independence on the patient's daily activities. The aim of this study was to investigate the effect of magnetic field therapy on the shoulder pain of patients with subluxation after stroke.

In this double-blind randomized, clinical trial, 36 patients with stroke who referred to the Tabassom rehabilitation stroke center in Tehran, complained of subluxation and shoulder pain, were included in the study by randomized sampling. After assigning patients in two groups of 19, in the intervention group, the magnetic shoulder support with the intensity of 1500 Guess and in the control group were used the shoulder without the magnetic feature for 48 hours continuous. Before and after the intervention, the pain was measured by the visual analog scale (VAS). Data were analyzed by SPSS software version 18 and using descriptive and inferential statistics. The significance level was considered (0.05).

The majority of the intervention group (66.7%) were women and the control group was male (66.7%). There was no significant difference between the mean pain score of hands in two groups before intervention. However, after the magnetic therapy, the mean score of pain in the intervention group was significantly decreased (p = 0.001), but the changes in the control group were not significant.

Magnetic therapy in patients with stroke reduces shoulder pain. Magnetic therapy can replace or complement other therapeutic and surgical treatment for shoulder pain
