The Effects of Augmenting Balance Training with Stroboscopic Goggles on Postural Control in Chronic Ankle Instability Patients: A Critically Appraised Topic.

Abstract

Clinical scenario: Individuals with chronic ankle instability (CAI) typically complete balance training protocols to improve postural control and reduce recurrent injury risk. However, the presence of CAI persists after traditional balance training protocols suggesting that such programs may be missing elements that could be beneficial to patients. Visual occlusion modalities, such as stroboscopic goggles, may be able to augment balance training exercises to further enhance postural control gains in those with CAI. However, a cumulative review of the existing evidence has yet to be conducted.

Focused clinical question: Does wearing stroboscopic goggles during balance training result in greater improvements to postural control than balance training alone in those with CAI?

Summary of key findings: All 3 studies indicated that the stroboscopic goggles group had statistically significant improvements in either a measure of static or dynamic postural control relative to the standard balance training group. However, significant improvements were not consistent across all postural control outcomes assessed in the included studies.

Clinical bottom line: Postural control may improve more in those with CAI when stroboscopic goggles were worn while completing balance training exercises relative to completing balance training exercises alone.

Strength of recommendation: Overall, consistent moderate- to high-quality evidence was present in the 3 studies, suggesting grade C evidence for the use of stroboscopic goggles during balance training in those with CAI.
