Accessibility Online ahead of print. The site is secure. To our knowledge, no authors have assessed health-related quality of life (HR-QOL) in participants with functional ankle instability (FAI). Participants with FAI had lower scores on the SF-36 physical component summary (FAI = 54.4 5.1, UI = 57.8 3.7, P = .005), physical function domain scale (FAI = 54.5 3.8, UI = 56.6 1.2, P = .004), and bodily pain domain scale (FAI = 52.0 6.7, UI = 58.5 5.3, P < .005). Furthermore, positive correlations were found between HR-QOL and functional limitation measures. This suggests that ankle impairment may reduce overall HR-QOL.

An official website of the United States government. This activation deficit, referred to as arthrogenic muscle inhibition (AMI), may be . Clinical relevance: We suggest clinicians and researchers utilize the IdFAI to identify individuals with functional ankle instability since it is a short, simple, easy questionnaire to administer and take, and has been shown to have excellent accuracy. Of these the latter is considered the gold standard, even though it is an invasive procedure, it may not be performed for diagnostic reasons only, and it also does not allow the mechanical instability to be quantified. The purpose of this study was to determine which . Foot Ankle Int, 1999,20:636-9. Conclusions: 8600 Rockville Pike 2022 Sep 21;13:923669. doi: 10.3389/fneur.2022.923669. The factors currently thought to contribute to CAI include mechanical and functional deficits, which focus on impairment as a direct result of pathology.8 This view of CAI provides an explicit and thorough illustration of the arthrokinematic, structural, neuromuscular, and proprioceptive deficits thought to contribute to this condition, but not necessarily the . MeSH terms Adolescent Adult Ankle Joint* Factor Analysis, Statistical Female Study design: On clinical exam, the ankle ligaments appear stable and within normal limits, but the patient continues to have pain experiences a feeling of instability when putting weight on it. the term functionally unstable ankle was first introduced by freeman et al 4 and has been refined to mean joint motion beyond voluntary control but not necessarily exceeding physiologic (anatomical) range of motion. Damage to mechanoreceptors within the lateral ankle ligaments after injury is hypothesized to interrupt neurologic feedback mechanisms resulting in functional ankle instability.
