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 …

Cross-Education Balance Effects After Unilateral Rehabilitation In Individuals With Chronic Ankle Instability: A Systematic Review, Briana Lawry-Popelka, Sunghoon Chung, Ryan S. Mccann

Rehabilitation Sciences Faculty Publications

Objective: To conduct a systematic review of existing literature on cross-education balance effects after unilateral training in the population with chronic ankle instability (CAI).

Data Sources: PubMed, SPORTDiscus, CINAHL Plus.

Study Selection: To be included in the systematic review, studies were required to have been published in English, included participants with CAI, had participants undergo a unilateral therapeutic exercise for the lower extremity, and measured balance performance of the untrained lower extremity before and after the intervention.

Data Extraction: The certainty of evidence in each included study was assessed via the Downs and Black checklist. A score of 24 to …
