Abstract: BACKGROUND: Cervical rotation manipulation has a positive effect on the treatment of cervical spondylotic radiculopathy, but improper use of manipulation can easily cause adverse consequences. By comparing the inclined pull manipulation and rotation-traction manipulation that are commonly used in clinical practice and have a set of standard operating procedures, it provides clinical safety guidance for the manipulation. 
OBJECTIVE: To measure the difference in range of motion of cervical spine in the inclined pull manipulation and rotation-traction manipulation by motion capture technology, and to investigate the movement characteristics and the safety of two kinds of manipulations.
METHODS: Totally 20 healthy subjects (10 males and 10 females) were selected and randomly divided into two groups. The 10 subjects (5 males and 5 females) in each group were subjected to inclined pull manipulation (group 1) and rotation-traction manipulation (group 2), respectively, to measure the active and passive movements of cervical spine and the range of motion of the subphysiological areas. This study was approved by the Medical Ethics Committee of Shunde Hospital Affiliated to Guangzhou Medical University.
RESULTS AND CONCLUSION: The active and passive ranges of motion of the group of inclined pull method and the group of rotation-traction manipulation were not significantly different (P > 0.05). The range of motion in the subphysiological region of the group of inclined pull method was larger than that in the group of rotation-traction manipulation; the range of motion in the left subphysiological region was larger than that in the right region in the group of inclined pull method (P < 0.05). However, the range of motion in the subphysiological region was similar between both sexes (P > 0.05). The range of motion in the subphysiological region was similar between the left and right sides between both sexes in the group of rotation-traction manipulation (P > 0.05). It is concluded that the subphysiological area of cervical rotation-traction manipulation is smaller than that of inclined pull method, and the technique is more stable and balanced.
