Figure 2

Values of the cervical kinematic variables for the neck pain and the control subjects. Peak Speed plotted against the other kinematic variables. Filled circles represent the neck pain subjects (n = 118) and open circles represent the controls (n = 49). ROM: Range of movement; CM: Conjunct movements; SID: Speed index of deviation from the minimum-jerk model; NPA: Normalized peak speed amplitude; A/D-ratio: Acceleration-deceleration ratio.
