“…In cases of ankle instability, the ankle eversion muscle is weakened [9], and there is hip and lumbopelvic muscle weakening [12,32]. The tibialis anterior functions to prevent the foot from being dragged through the dorsiflexion while walking and to prevent the inversion, or plantar flexion, which is a posture that can lead to ankle sprain.…”

In subjects with functional ankle instability, lumbopelvic instability causes instability of the hip and lower extremities. The purpose of this study is to determine whether an ankle exercise program with hip strengthening exercise and lumbopelvic stabilization exercise affects spine and ankle stability through muscle activity in adults with functional ankle instability. Thirty adults with functional ankle instability were randomly assigned to a hip joint strengthening exercise group and a lumbopelvic stabilization exercise group. The subjects participated in the designated program three times a week for 40 minutes a day. In the hip joint strengthening exercise group, a general hip joint strengthening exercise was used, and in the lumbopelvic stabilization exercise group, a lumbopelvic stabilization exercise using a sling was added. The intervention lasted 4 weeks, and both groups were instructed to refrain from other exercise during the 4-week intervention period. The muscle activity of the tibialis anterior, gluteus maximus, external oblique and contralateral latissimus dorsi was measured. Data were collected from the 30 patients. The results showed that the muscle activity of the tibialis anterior, gluteus maximus, lateral oblique muscle, and contralateral latissimus dorsi was significantly increased in both groups. This suggests that the existing hip joint strengthening exercise and lumbopelvic stabilization exercise are effective approaches which not only help reduce hip joint pain and improve function, but also reduce functional ankle instability. Therefore, if an appropriate exercise program is provided for subjects with functional ankle instability, it is expected that it will help improve pain and function by reducing ankle instability and the frequency of re-injury.

Ankle joint Electromyography Eversion Peroneal muscle PostureBackground: Lateral instability of the ankle is one of the most common causes of musculoskeletal ankle injuries. The peroneus longus (PL) and peroneus brevis (PB) contribute to ankle stability. In early rehabilitation, isometric exercises have been selected for improvement of ankle stability. To effectively train the peroneal muscles during eversion, it is important to consider ankle and body posture. Objects: This study aimed to compare activation of the PL, PB, and biceps femoris (BF) muscles during eversion in different ankle postures (neutral [N], plantarflexed [PF]) and body postures (sitting and side-lying).Methods: Thirty healthy individuals with no history of lateral ankle sprains within the last 6 months were included in the study. Maximal isometric strength of eversion and muscle activation were measured simultaneously. Muscle activation at submaximal eversion was divided by the highest value obtained from maximal isometric eversion among the four postures (percent maximal voluntary isometric contraction [%MVIC]). To examine the differences in muscle activation depending on posture, a 2 × 2 repeated measures analysis of variance (ANOVA) was conducted.Results: There were significant interaction effects of ankle and body postures on PL muscle activation and evertor strength (p < 0.05). The PL muscle activation showed a significantly greater difference in the side-lying and PF conditions than in the sitting and N conditions (p < 0.05). Evertor strength was greater in the N compared to the PF condition regardless of body posture (p < 0.05). In the case of PB and BF muscle activation, only the main effects of ankle and body posture were observed (p < 0.05). Conclusion:Among the four postures, the side-lying-PF posture produced the highest muscle activation. The side-lying-PF posture may be preferred for effective peroneal muscle exercises, even when considering the BF muscle.

“…Local muscle fatigue may have effects exercise performance and loading, causing the stress distribution on the musculoskeletal structure to change ( RADIN, 1986 ; Christina et al, 2001 ; Kellis and Liassou, 2009 ; Tiwari et al, 2021 ; Yahya et al, 2022 ). As a major player in ankle motion, the dorsiflexors use concentric contraction to increase dorsiflexion before landing in a lunge to provide adequate landing cushion range ( Kim et al, 2017 ). With a greater range of motion (ROM) in the ankle dorsiflexion, the body can take less impact when landing and be more cushioned.…”

“…During the landing phase of the lunge, the dorsiflexors alternate with the plantar flexors; although the plantar flexors are dominant, the dorsiflexors also have an irreplaceable role. It has been shown that when the knee is flexed beyond 90°, the plantar flexors’ eccentric contraction increases during lunge landing, but the dorsiflexors also increase their activity and contribute to ankle stability ( Lees and Hurley, 1994 ; Kim et al, 2017 ; Lee and Loh, 2019 ). Furthermore, the effect of dorsiflexor fatigue on ankle motion during landing is currently unknown.…”

Background: Local muscle fatigue may have an adverse effect on the biomechanics of the lunge movement and athletic performance. This study analyzed the biomechanical indicators of the forward lunge in badminton players before and after fatigue of the ankle dorsiflexors.Methods: Using the isometric muscular strength testing system, 15 badminton players underwent an ankle dorsiflexor fatigue test. Before and after the fatigue experiment, five lunges were done in both the forehand forward (FH) and backhand forward (BH) directions, five in each direction. A Vicon motion capture system and an AMTI force measuring station were used to record lower limb kinematic and ground reaction force (GRF). Pre-fatigue and post-fatigue variability were determined using paired-samples t-tests, Wilcoxon signed rank test, and Statistical Non-parametric Mapping (SNPM).Result: The results showed that after fatigue, the peak angle of ankle dorsiflexion was significantly reduced (p = 0.034), the range of motion (ROM) of the ankle sagittal plane (p = 0.000) and peak angle of ankle plantarflexion (p = 0.001) was significantly increased after forehand landing. After fatigue, ankle inversion was significantly increased after forehand and backhand landings (FH: p = 0.033; BH: p = 0.015). After fatigue, peak knee flexion angles increased significantly (FH: Max: p = 0.000, Min: p = 0.000; BH: Max: p = 0.017, Min: p = 0.037) during forehand and backhand landings and ROM in knee flexion and extension increased (p = 0.009) during forehand landings. Knee inversion range of motion was significantly increased after fatigue (p = 0.024) during forehand landings. Peak hip flexion angle (p = 0.000) and range of motion (p = 0.000) were significantly reduced in forehand landings after fatigue. The mean loading rate (p = 0.005) and the maximum loading rate (p = 0.001) increased significantly during backhand landings after fatigue. Post-fatigue, the center of pressure (COP) frontal offset increased significantly (FH: p = 0.000; BH: p = 0.000) in the forehand and backhand landings.Conclusion: These results indicate that when the ankle dorsiflexors are fatigued, the performance of the forehand is significantly negatively affected, and the impact force of the backhand is greater.
