The purpose of this study is 1) to analyze peroneal muscle activity inter-limb differences in athletes with history of ankle sprain and 2) to analyze peroneal muscle activity differences between athletes with and without history of an ankle sprain.
This observational cross-sectional study included sixty-seven athletes (53% females). Self-reported data regarding history of ankle sprain were collected. Peroneal myoelectrical activity was obtained during 1) isometric ankle eversion, 2) dynamic ankle eversions, 3) single leg squat, 4) and 5) unilateral and bilateral drop jump test, 6) sprint, and 7) change of direction.
There were no significant peroneal myoelectrical activity differences between those with (n=46) and without (n=21) a history of ankle sprain during the last six months (p>0.05). There was also no inter-limb difference within the previous ankle sprain group (p>0.05).
This study examined the myoelectric activity of the peroneus longus and brevis muscles in athletes with and without a history of ankle sprain injury. The results suggest that there is no significant difference in the myoelectric activity of the peroneal muscles between athletes with and without a history of ankle sprain in the last six months. Furthermore, the myoelectric activity of the peroneal muscles in athletes who have suffered an ankle sprain in the last six months does not show any significant difference between the previously injured limb and the uninjured limb. These findings provide valuable insights into the effects of ankle sprain injury on myoelectric activity and could inform the development of rehabilitation strategies for individuals with a history of ankle sprains. Future studies should focus on investigating other neuromuscular factors such as muscle tone, muscle strength, and joint stiffness, as well as the relationship between myoelectric activity and the severity of ankle sprains and the length of time elapsed since the injury. Such information could aid in the development of effective rehabilitation strategies for individuals with a history of ankle sprains.
Peroneal muscle activity inter-limb differences were not found in athletes with history of ankle sprain during the last six months. Moreover, peroneal muscle activity does not differ between athletes with and without history of ankle sprain. The rehabilitation of an ankle sprain appears to restore peroneal myoelectric activity, and from an electrical activity standpoint, the athlete should not be considered a risk following an ankle sprain.
