OBJECTIVES: To investigate the validity of a novel method for assessing intra-foot proprioception impaired by chronic ankle instability (CAI) and its association with perceived ankle instability, and to include a conventional joint position reproduction (JPR).
DESIGN: Case-control study.
SETTING: University laboratory.
PARTICIPANTS: Eleven controls and 19 individuals with CAI.
MAIN OUTCOME MEASURES: A circumduction reproduction test was developed to evaluate proprioception by measuring absolute errors between eyes-opened and closed conditions during ankle circumduction movement, consisting of inversion and eversion phases. Errors in hallux marker trajectory and intra-foot joint relative angles were analyzed. Additionally, the JPR was administered to comparison with the novel method.
RESULTS: During the eversion phase, the CAI group had significantly more errors in the X and Y component than the control group. The Pearson's r between the X component and IdFAI was 0.354 (p = 0.054). The X component correlated with the movement of the rearfoot, midfoot and forefoot, with correlations of r > 0.4. However, the JPR did not detect differences between two groups (p > 0.05).
CONCLUSIONS: The circumduction reproduction test has discriminant validity for distinguishing between two groups and may provide an advantage over JPR.
