Abstract

This double-blind, randomized controlled study was conducted with the aim to investigate the effect of magnetic field therapy applied to the hip region on clinical and functional status in ankylosing spondylitis (AS) patients. Patients with AS (n = 66) who were diagnosed according to modified New York criteria were enrolled in this study. Patients were randomly divided in two groups. Participants were randomly assigned to receive magnetic field therapy (2 Hz) (n = 35), or placebo magnetic field therapy (n = 31) each hip region for 20 min. Patients in each group were given heat pack and short-wave treatments applied to bilateral hip regions. Both groups had articular range of motion and stretching exercises and strengthening exercises for surrounding muscles for the hip region as well as breathing and postural exercises by the same physical therapist. These treatment protocols were continued for a total of 15 sessions (1 session per day), and patients were examined by the same physician at months 1, 3 and 6. Visual analogue scale (VAS) pain, VAS fatigue, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrologic Index (BASMI), DFI, Harris hip assessment index and Ankylosing Spondylitis Quality of Life scale (ASQOL) were obtained at the beginning of therapy and at month 1, month 3 and month 6 for each patient. There were no significant differences between groups in the VAS pain, VAS fatigue, morning stiffness, BASDAI, BASFI, BASMI, DFI, Harris hip assessment index and ASQoL at baseline, month 1, month 3 or month 6 (p > 0.05). Further randomized, double-blind controlled studies are needed in order to establish the evidence level for the efficacy of modalities with known analgesic and anti-inflammatory action such as magnetotherapy, particularly in rheumatic disorders associated with chronic pain.
