“…The limb with less ankle stability was chosen as the test limb. In order to normalize the EMG data, maximum voluntary isometric contraction (MVIC) tests were conducted for each muscle of the test limb using previously published procedures (see Ref 24 . for detailed procedures) 25, 26, 27.…”

BackgroundSeveral case studies observed that the lateral ankle sprain resulted from a sudden increase in ankle inversion accompanied by internal rotation. However, without sufficient ankle kinetics and muscle activity information in the literature, the detailed mechanism of ankle sprain is still unrevealed. The purpose of our case report is to present 2 accidental ankle giving way incidents for participants with chronic ankle instability (CAI) and compare to their normal trials with data of kinematics, kinetics, and electromyography (EMG).Case descriptionTwo young female participants accidentally experienced the ankle giving way when landing on a 25° lateral-tilted force plate. 3D kinematics, kinetics, and muscle activity were recorded for the lower extremity. Qualitative comparisons were made between the giving way trials and normal trials for joint angles, angular velocities, moments, centers of pressure and EMG linear envelopes.ResultsOne participant's giving way trial displayed increased ankle inversion and internal rotation angles in the pre-landing phase and at initial contact compared to her normal trials. Another participant's giving way trial exhibited greater hip abduction angles and delayed activation of the peroneus longus muscle in the pre-landing phase versus her normal trials.ConclusionA vulnerable ankle position (i.e., more inverted and internally rotated), and a late activation of peroneus activity in the pre-landing phase could result in the ankle giving way or even sprains. A neutral ankle position and early activation of ankle evertors before landing may be helpful in preventing ankle sprains.

“…Donnelly et al 16 found important force deficits in the long and short fibular muscles, responsible for the eversion movement in the ICT group in different ankle positions. Li et al 5 and Suda et al 14 found a reduction in the long fibular activity and a higher recruitment of the anterior tibial in the pre-landing phase, and established that rehabilitation should stimulate a greater long fibular muscle recruitment. It is complemented that for the treatment and prevention of inverted sprains, the coordinated contraction of the anterior tibial and long fibular muscles should be stimulated 12 .…”

“…It is estimated that the annual incidence rate of this lesion is 2.15 to 1.000 people for the general population, with an increase of this rate to 58 sprains per 1,000 athletes 2 . It is believed that ICT is based on lateral ankle sprain (LAS), it is one of the most common lesions in sport 3 , it happens by the combined movement of plantar flexion and ankle inversion 4 , and the condition can be maintained for more than 12 months after the first episode [4][5][6] . The primary causes are mechanical instability (anatomical changes) and functional (subjective sensation of ankle instability) or the combination of both.…”

Chronic ankle instability (ICT) is common in jumping sports, may alter muscle recruitment, result in functional limitations and recurrence of sprains in this joint. The purpose of the study was to compare the muscle recruitment of the anterior tibial and long fibular muscles of athletes with and without chronic ankle instability by means of surface electromyography. Thirty-four athletes were recruited, divided into instability group (GI: n=14) and control group (GC: n=20), of both sexes and from different sport modalities, aged between 18 and 27 years old, history of ankle sprain in the last 12 months and functional limitation established by the Cumberland Ankle Instability (CAIT) questionnaire, the recruitment of the anterior tibial and long fibular muscles was analyzed by surface electromyography during the lunge exercise. The results for GI and GC were, respectively: age 21.3±2.88 and 22.4±3.25, height 1.77±0.10 and 1.74±0.08, CAIT 17[12.2-19] and 29.5 [27-30] (p<0.001). The anterior tibial and long fibular muscle recruitment in GI was 111.1[62.5-165.4] and 68.2±29, respectively and in GC 106.8[79.8-230.5] and 54.4±26.4, without significant difference. ICT did not interfere in the recruitment of the anterior tibial and long fibular muscles during the lunge exercise in athletes. Keywords: Ankle. Sprains and Strains. Health Evaluation. ResumoA instabilidade crônica do tornozelo (ICT) é comum em esportes de saltos, pode alterar o recrutamento muscular, resultar em limitações funcionais e recidivas de entorses nesta articulação. O objeto do estudo foi comparar o recrutamento muscular dos músculos tibial anterior e fibular longo de atletas com e sem instabilidade crônica de tornozelo por meio da eletromiografia de superfície. Foram recrutados 34 atletas, divididos em grupo instabilidade (GI: n=14) e grupo controle (GC: n=20), de ambos os sexos e de diferentes modalidades esportivas, com idade entre 18 e 27 anos, história de entorse de tornozelo nos últimos 12 meses e limitação funcional estabelecida pelo questionário Cumberland Ankle Instability (CAIT), o recrutamento dos músculos tibial anterior e fibular longo foi analisado pela eletromiografia de superfície durante o exercício de agachamento afundo. Os resultados para GI e GC foram, respectivamente: idade 21,3±2,88 e 22,4±3,25, altura 1,77±0,10 e 1,74±0,08, CAIT 17[12,2–19] e 29,5 [27-30] (p<0,001). O recrutamento muscular do tibial anterior e fibular longo no GI foi 111,1[62,5-165,4] e 68,2±29, respectivamente e no GC 106,8[79,8-230,5] e 54,4±26,4, sem diferença significativa. A ICT não interferiu no recrutamento dos músculos tibial anterior e fibular longo durante a realização do exercício de agachamento afundo em atletas. Palavras-chave: Tornozelo. Entorses e Distensões.

“…3,5 Improved muscle activation can provide stability, thus decreasing the risk for injury to occur during landing. 6,8,[18][19][20][21] There is a relationship between the proximal and distal joints of our lower extremity. 16,17 Following the kinetic linking, ankle invertors, evertors, and GMeds are responsible for movements and stability in the frontal plane of the ankle joint.…”

“…These reported alteration in patterns of muscular activation of these muscles during landing, thereby increasing the risk of reinjury of people with chronic ankle sprain. 6,19 Most studies on muscle activation of GMeds were done in either single-leg landings or lateral hops. [21][22][23] Several studies used force plates also to gather the force generated by the muscles.…”

Background: Gluteus medius (GMeds), peroneus longus (PL), and tibialis anterior (TA) help in maintaining frontal stability of the lower extremity, particularly, the ankle. Muscle activation must be sufficient to prevent the occurrence of an ankle sprain. The purpose of this study is to compare the muscle activation of the GMeds, TA, and PL during drop landing on stable and unstable surfaces of physically active individuals. Methods: Surface EMG (sEMG) was used to determine the muscle activation pattern of the GMeds, TA, and PL of fifteen ( 15) recreational athletes during drop landing. The mean percentage of maximum voluntary isometric contraction (%MVIC) was calculated for comparison. Wilcoxon signed-rank test was used to compare means. Results: There were no statistically significant differences in the muscle activity of GMeds (p=0.69), TA (p=0.26), and PL (p=0.23) on stable and unstable surfaces. However, a small effect size showed that GMeds (d=0.30) has higher activation in the unstable surface while TA (d=0.28) and PL (d=0.17) have lower activation on unstable surface. Conclusion: Landing surface does not significantly alter muscle activity of GMeds, TA, and PL. However, the magnitude of the difference in the mean %MVIC between groups shows the compensatory mechanism of the body when subjected to different surface conditions. This can be used when creating injury prevention programs of the lower extremity.
