Kinematics Analysis of Cervical Rotation-Traction Manipulation Measured by a Motion Capture System

Table 1

Movement process of the active rotary-position (units: angle).

Side	Step  1 rotation	Step  2 flexion	Step  3 rotation again
Right	69.49 (10.17)	27.87 (8.07)	11.03 (5.00)
Left	−72.59 (9.44)	27.10 (6.29)	10.95 (5.90)

Notes. Forward flexion, right side rotation, and right lateral flexion are positive.
