Abstract
Introduction: Magnetic field is used in therapies designed for patients with rheumatic disorders such as rheumatoid arthritis (RA). The question of selecting adequate treatment parameters to obtain optimal therapeutic effects still needs to be answered. The purpose of the study was to assess the influence of magnetic field, depending on its nature, on problems and dysfunctions experienced in upper limbs by patients with RA.
Materials and methods: The study group included 14 patients with RA (10 females, 4 males), referred for magnetotherapy to be administered in selected areas of upper limbs. On average, the subjects were 57 years old, and the mean duration of the disorder was 13 years. Magnetotherapy was administered with the use of static or pulsed magnetic field. The patients were examined for the level of disorder, disability level (HAQ-20), severity and duration of morning stiffness, pain intensity (VAS scale), hand volume, swelling and functional capacity. The examinations were carried out before and after a series of ten magnetotherapy treatments.
Results: All the patients reported decreased severity and shorter duration of morning stiffness, reduced level of pain and general disability. There was no statistically significant difference between the groups treated with static and pulsed magnetic field. Statistically significant differences between the groups treated with static and pulsed field were observed in reduced swelling, improved range of motion and muscle strength in the upper limb. The study revealed better effects of pulsed field therapy.
Conclusions: When administered to areas within upper limbs in patients with RA, pulsed magnetic field produced better effects related to the reduction of swelling as well as improving range of motion and muscle strength in the relevant area of the body compared to static field. The findings did not confirm the relationship between the type of magnetic field and its therapeutic effectiveness in reducing pain, morning stiffness and disability level.
