More research on the peronei and chronic ankle instability.
/More peroneii action! In folks with chronic ankle instability, it contracts earlier, longer (throughout stance phase) but not stronger…This article looks at activation times and patterns of folks with chronic ankle instability.
One should never wonder why repeated ankle sprains occur. We have hit this topic hard in the past. Chronic Ankle Instability (CAI) clients exhibit prioprioceptive and postural control challenges. According to this article, additionally, CAI clients have measurable gait changes.
“Time of activation for all muscles tested occurred earlier in the CAI group than in the control group. The peroneus longus was activated for a longer duration across the entire stride cycle in the CAI group.”
“Individuals with CAI demonstrated neuromuscular-activation strategies throughout the lower extremity that were different from those of healthy control participants. ”
Did you see our trademark “goto” exercise in yesterday’s social media Facebook blog post ? It is a keeper if you ask us. Don’t ignore chronic peroneal challenges, they will come back to haunt you.
