Purpose: The aim of the study was to determine whether corticospinal excitability and inhibition of the tibialis anterior during single-leg standing differs among individuals with chronic ankle instability (CAI), lateral ankle sprain copers, and healthy controls.

Methods: Twenty-three participants with CAI, 23 lateral ankle sprain copers, and 24 healthy control participants volunteered. Active motor threshold (AMT), normalized motor-evoked potential (MEP), and cortical silent period (CSP) were evaluated by transcranial magnetic stimulation while participants performed a single-leg standing task.

Results: Participants with CAI had significantly longer CSP at 100% of AMT and lower normalized MEP at 120% of AMT compared to …

Lumbopelvic Stability And Trunk Muscle Contractility Of Individuals With Chronic Ankle Instability, Ryan S. Mccann, Kelly Johnson, Ashley M.B. Suttmiller

Rehabilitation Sciences Faculty Publications

BACKGROUND: Chronic ankle instability (CAI) results in hip neuromuscular impairments that can perpetuate dysfunction through reduced lumbopelvic stability and subsequent malpositioning of the lower body during functional movement. Lumbopelvic stability might be further impaired through changes in trunk muscular contractility. However, lumbopelvic stability and trunk muscle morphology have not been compared between individuals with and without CAI.

PURPOSE: To compare lumbopelvic stability and trunk muscle contractility between individuals with and without chronic ankle instability (CAI) and determine if lumbopelvic stability and trunk muscle contractility are associated with self-reported function.

STUDY DESIGN: Case-control study.

METHODS: Ten individuals with CAI, 10 …

The Effect Of Fibular Reposition Taping On Postural Control In Individuals With Chronic Ankle Instability: A Critically Appraised Topic, Bradley C. Jackson, Robert T. Medina, Stephanie H. Clines, Julie M. Cavallario, Mathew H. Hoch

Rehabilitation Sciences Faculty Publications

Clinical Scenario: History of acute ankle sprains can result in chronic ankle instability (CAI). Arthrokinematic changes resulting from CAI may restrict range of motion and contribute to postural control deficits. Mulligan or fibular reposition taping (FRT) has been suggested as a means to realign fibular positional faults and may be an effective way to improve postural control and balance in patients with CAI. Clinical Question: Is there evidence to suggest that FRT will improve postural control for patients with CAI in the affected limb compared with no taping? Summary of Key Findings: Three of the 4 included studies found no …
