Neck pain is very common. It can negatively affect the patient's life and may result in disability. This study conducted to compare the effect of different Mulligan techniques which is more effective (Mulligan self-mobilization or Mulligan SNAGs) on cervical position sense, pain and function. Methods: 87 subjects with chronic mechanical neck pain, three groups were randomly assigned to Group(1)29 subjects received Mulligan self-mobilization and traditional treatment. Group (2)29 subjects

... d Mulligan SNAGs and traditional treatment. Group(3)29 subjects received traditional treatment only. Position sense measured by Joint reposition error, pain measured by visual analog scale and function by Functional Neck disability index. Measurements were taken pre and post the intervention period. Results: MANOVA test revealed that there was significant improvement in values of the post-treatment in all Groups compared with pre-treatment of JPE(pre:P=0.725, post:P<0.001), VAS(pre=0.984, post:P<0.001) and NDI(pre=0.903, post:P<0.001). Conclusion: It can be reasoned that both Mulligan self-mobilization and Mulligan SNAGs techniques have a similar effect in JPE, VAS and NDI more than traditional in chronic mechanical neck pain patients.
