Abstract
Context: Lateral ankle sprain (LAS) is one of the most common musculoskeletal injuries in both athletic and general population. Up to 70% of patients with acute LAS develop chronic ankle instability (CAI) characterized by repetitive ankle giving way perception, persistent symptoms, reduced self-reported function, and recurrence of ankle sprain. From initial lateral ankle sprain, structural abnormalities with afferent receptors damage can cause the impairment of proprioception that consists of joint position sense, force sense, and kinesthesia Proprioception involves complex interactions between incoming afferent somatosensory information from cutaneous, articular, and musculotendinous receptors, and CNS. The afferent information is combined and processed to determine to elicit outgoing efferent responses as motor commands such as postural control that requires integration of visual, vestibular, and the somatosensory afferent input. Thus, proprioception impairment and postural control deficit from LAS are interacted with each other in the perception-action cycle between sensory-perceptual impairment and motor-behavior impairment in sensorimotor control, which contributes to another LAS and CAI. However, there is lack of evidence to suggest relation between proprioception performance and postural control in patients with CAI.
Objectivity: We aim to identify the correlation between proprioception performance and postural control deviation in individuals with CAI.
Design: Cross-sectional study
Participants: Thirty subjects with unilateral or bilateral chronic ankle instability participated in this study.
Main outcome measures: Joint position sense: The mean of absolute difference between each the target angle (5 degrees and 20 degrees of inversion) and reproduced angle of each three trials were utilized as dependent variables for analysis. Force sense: From 20 percent of maximum voluntary isometric contraction (MVIC) of eversion at 5 degrees and 15 degrees inversion, the difference between peak values during the 20 percent reproduction of the MVIC with and without visual information were utilized as dependent variables for analysis. Postural control: The average position of COP data points and standard deviation from 3 trials of eyes-opened single leg balancing and 3 trails of eyes-closed single leg balancing were utilized as dependent variables for analysis.
