BACKGROUND Chronic ankle instability (CAI) is a major condition in athletes. It is known that both ankle joint proprioception and joint motion control are important for the improvement of CAI, but the relationship between the two has not been clarified. The purpose of this study was to compare ankle-joint angle in dynamic balance tasks and ankle-joint proprioception in healthy and CAI individuals and to verify the relationship between ankle-joint angle in dynamic balance tasks and ankle-joint proprioception in individuals with CAI. METHODS The participants were 27 females (age 20.3±0.9 years, healthy group: 15, CAI group: 12). The star excursion balance test (SEBT) was used for the dynamic balance task, and the ankle joint angles were measured with a small accelerometer during the movement. The error of the active joint repositioning test (AJRT) was measured to test the proprioception. RESULTS There was no significant difference in the error in AJRT between the groups, but the joint angle in SEBT was significantly lower in the CAI group than in the healthy group for ankle dorsiflexion only. The error in AJRT of ankle inversion was correlated with the ankle inversion/eversion angle of the SEBT, and the error in AJRT of ankle plantar flexion was correlated with the ankle-dorsiflexion angle of the SEBT. CONCLUSIONS CAI individuals showed no difference in ankle-joint proprioception compared to healthy individuals, but their ankle-joint-dorsiflexion angle in the dynamic balance task was smaller. Ankle-joint proprioception in CAI individuals was related to the ankle-joint angle in the dynamic balance task.

D007593 Joint Instability Lack of stability of a joint or joint prosthesis. Hypermobility, Joint,Instability, Joint,Laxity, Joint,Hypermobilities, Joint,Instabilities, Joint,Joint Hypermobilities,Joint Hypermobility,Joint Instabilities,Joint Laxities,Joint Laxity,Laxities, Joint
D011434 Proprioception Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE. Labyrinthine Sense,Position Sense,Posture Sense,Sense of Equilibrium,Vestibular Sense,Sense of Position,Equilibrium Sense,Sense, Labyrinthine,Sense, Position,Sense, Posture,Sense, Vestibular
D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D004856 Postural Balance A POSTURE in which an ideal body mass distribution is achieved. Postural balance provides the body carriage stability and conditions for normal functions in stationary position or in movement, such as sitting, standing, or walking.

D016059 Range of Motion, Articular The distance and direction to which a bone joint can be extended. Range of motion is a function of the condition of the joints, muscles, and connective tissues involved. Joint flexibility can be improved through appropriate MUSCLE STRETCHING EXERCISES.
