Objective:
To investigate whether joint position sense (JPS) accuracy differs between subjects with a history of subclinical neck pain syndrome (SCNPS) and those with no neck complaints, and to see whether adjusting dysfunctional cervical segments in the SCNPS group improves their JPS accuracy.

Methods:
Twenty-five SCNPS subjects and 18 control subjects participated in this study. Elbow JPS was measured utilising an electrogoniometer. Subjects reproduced a previously presented angle of the elbow joint with their neck in four positions: neutral, flexion, rotation, and combined flexion/rotation. The experimental intervention was high velocity, low-amplitude cervical adjustments and the control intervention was a 5-minute rest period. Group JPS data were compared and assessed pre- and post interventions using three parameters: absolute, constant, and variable error.

Results:
At baseline the control group was significantly better at reproducing the elbow target angle. The SCNPS group’s absolute error significantly improved following the cervical adjustments when the subjects’ heads were in the neutral and left rotation positions. They displayed a significant overall decrease in variable error following the cervical adjustments. The control group subjects’ JPS accuracy was worse after the control intervention with a significant overall effect in absolute and variable error. No other significant effects were detected.

Conclusion:
These results suggest that asymptomatic people with a history of SCNPS have reduced elbow JPS accuracy compared with those with no history of any neck complaints. Furthermore, the results suggest that adjusting dysfunctional cervical segments in people with SCNPS can improve their upper limb JPS accuracy.
