Proprioceptive imprecision is believed to contribute to persistent
pain. Detecting imprecision in order to study or treat it remains challenging
given the limitations of current tests. OBJECTIVES:
The aim of this study was to
determine whether proprioceptive imprecision could be detected in people with
neck pain by testing their ability to identify incongruence between true head
motion and a false visual reference using the Proprioception Incongruence
Detection (PID) Test. DESIGN:
A cross-sectional study was conducted. METHODS:
Twenty-four people with neck pain and 24 matched controls repeatedly rotated to
specific markers within a virtual world and indicated if their true head rotation
was more or less than the rotation suggested by the visual feedback. Visual
feedback was manipulated at 6 corrections, ranging from 60% of true movement to
140% of true movement. A standard repositioning error (RPE) test as undertaken
for comparison. RESULTS: Healthy controls were better able to detect incongruence
between vision and true head rotation (X=75.6%, SD=8.5%) than people with neck
pain were (X=69.6%, SD=12.7%). The RPE test scores were not different between
groups. The PID Test score related to self-reported pain intensity but did not
relate to RPE test score. LIMITATIONS: Causality cannot be established from this
cross-sectional study, and further work refining the PID Test is needed for it to
offer clinical utility. CONCLUSIONS: Proprioceptive precision for neck movement
appears worse in people with neck pain than in those without neck pain, and the
extent of the deficit appears to be related to usual pain severity. The PID Test
appears to be a more sensitive test than the RPE test and is likely to be useful
for assessment of proprioceptive function in research and clinical settings.
