Effects of pulsed electromagnetic field and retrowalking in patients with chronic non-specific low back pain: a pilot study

INTRODUCTION: Chronic non-specific low back pain (CNSLBP) is a major worldwide condition that has severe emotional, social, and economic consequences. Management is difficult, requiring the development of new, effective, and safe approaches. OBJECTIVES: This study was conducted to examine the effects of Pulsed Electromagnetic Fields (PEMF) and retrowalking on pain, disability, spinal mobility, hamstring tightness, balance, and kinesiophobia in patients with chronic non-specific low back pain. MATERIALS AND METHODS: Participants (n= 48) with CNSLBP were randomised into four groups; Group A: Conventional group, Group B: PEMF group, Group C: retrowalking group, and Group D: PEMF and retrowalking group. The interventions were given three times per week for six weeks. The outcomes were pain, disability, hamstring tightness, balance, spinal mobility and kinesiophobia, measured at baseline and after 6 weeks.  RESULTS: The result suggested a significant improvement in pain, disability, hamstring tightness, kinesiophobia and balance. However, no significant improvement in spinal mobility (flexion and extension ROM) was observed during the sixth week between-group comparison. The maximum improvement was seen in group D followed by group C and group B in comparison to group A. CONCLUSION: It can be concluded that PEMF and retrowalking when given in combination significantly decrease pain, disability, hamstring tightness, kinesiophobia and improve balance patients with chronic non-specific low back pain.
