Purpose : The purpose of this study was to compare Mulligan technique with Transcutaneous electrical nerve stimulation(TENS) in persons with neck pain. Methods : Twenty subjects with neck pain participated in the experiment. All subjects randomly assigned to the Mulligan technique group and TENS group. Both groups receive treatment(Mulligan technique: all areas 8 times once, TENS : 100Hz 15 minute once) 3 times during 2 weeks. And LEX was used to measure range of motion of neck. All measurement of each subject were measured at pre-treatment and post-treatment. Results : 1. All areas of range of motion of neck were significantly increased (p<0.05). 2. These data suggest that Mulligan technique and TENS are beneficial to increase all areas of range of motion of neck. 3. Comparing with two groups, Mulligan technique increases all areas of range of motion of neck more than TENS and appeared significant difference statistically. Conclusion : Mulligan technique is more effective than TENS to increse range of motion in persons with neck pain.
