Mechanical neck pain is a musculoskeletal disorder usually associated with work absenteeism. Myofascial release therapy (MRT) is currently under development and has the treatment of mechanical neck pain as one of its main focal points. However, there is a paucity of studies reporting its effectiveness. For that purpose a randomized single-blind parallel group study was designed to compare the effectiveness of MRT with manual therapy (MT) for treating occupational mechanical neck pain. The sample (n=59) was randomly assigned to two therapeutic intervention programs. Group I patients were treated with MT and Group II patients were treated with MRT. Variables studied were intensity of neck pain, cervical disability, quality of life (QoL), craniovertebral angle and ranges of cervical motion.
