Pulsed electromagnetic field versus pulsed ultrasound in treatment of mechanical neck pain: rct
Mechanical neck pain (MNP)affects approximately two thirds of the population in the middle age due to poor postural habits. Purpose: to compare the effect of pulsed electromagnetic field versus pulsed ultrasound on pain intensity, cervical range of motion and functional restriction in treating patients with MNP. Design: randomized controlled trial. Methods: 45 patients with MNP participated in this study.
