Figure 2

Conjunct motion during primary cervical rotation. Total conjunct motion for each primary cervical motion plane and group. The primary motions are denoted on the figure. Symbols illustrate mean range of total conjunct motion with 95% confidence intervals in the three study groups (A). The data in (B) are adjusted values for group differences in age, gender, current neck pain and primary range of motion. Significant group differences are denoted only in (B).
