The effect of low-level laser therapy and physical exercise on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis: a blind randomized clinical trial

This study sought to evaluate the effects of individual and combination therapies (low-level laser therapy and physical exercises) on pain, stiffness, function, and spatiotemporal gait variables in subjects with bilateral knee osteoarthritis. It concluded that a combination of exercise and laser therapy provided the best results for the other gait variables (cadence and duration of…

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

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