Abstract
Research on the proprioceptive mechanisms of the trunk typically involves trunk repositioning tasks. However, this body of research involves numerous differences in the test methods, results, and interpretations. This research tested the effects of two of the methodological differences, the visual condition and the speed of movement, along with the plane of motion, on the accuracy and precision of trunk repositioning ability in the three primary planes of trunk motion. The results showed significant main effects of plane of motion and visual condition on both repositioning accuracy and precision. Significant interactions between speed and plane of motion and between the visual condition and plane of motion were found for trunk repositioning accuracy. Finally, there was a strong correlation between the overall repositioning precision and the combined score of the Kinesthetic and Proprioceptive Assessment Questionnaire and the Body Awareness Questionnaire.
