Short-term effect of acupuncture dry needle in treatment of chronic mechanical low back pain: a randomized controlled clinical trial.

Objective: In today's industrialized world, between sixty and ninety percent of the working-age population experiences low back discomfort. Chronic mechanical low back pain (CMLBP), the most common ailment among working-age people in contemporary industrial society, causes a major economic burden due to the widespread use of medical services and the absence of work. For those suffering from persistent mechanical low back pain, this experiment aimed to assess the efficacy of using acupuncture dry needles in the short term.

Effect of pulsed electromagnetic field on nonspecific low back pain patients: a randomized controlled trial.

Background: Further research on pulsed electromagnetic field (PEMF) effects on the different conditions of low back pain was warranted due to lack of studies in this area.

Objectives: To investigate the effects of pulsed electromagnetic field therapy with 50Hz frequency, with low intensity of 20Gauss compared to conventional non-invasive treatment modalities in patients with chronic non-specific low back pain.

Methods: Design - A prospective, randomized, patient-blinded, controlled trial.
