“…They were asked to place both hands on their waist and maintain a slight knee flexion (≈0 • ). Level 8 (stable) to 6 (moderate) was considered in terms of athlete safety and the fact that lower levels fluctuate more [44]. Three 25-s tests with a 30-s resting interval were performed, and the overall score was considered.…”

Ankle sprain is a common musculoskeletal injury, and recurrent ankle sprains often lead to ankle instability. This study aimed to examine whether a 6-week balance training on a wobble board (WB) combined with kinesio taping (KT) is effective in improving balance, postural stability, and ankle stability among female athletes with functional ankle instability (FAI). Twenty-four female athletes with FAI were randomly assigned to study (SG) or control groups (CG). SG attended a 6-week training protocol of combined balance training on the wobble board with KT applied to ankles during exercise. CG only went through a 6-week balance training procedure that was the same as the SG. Before and after the training program, balance and postural stability and the severity of ankle instability were assessed by single-leg Biodex Balance system and Cumberland Ankle Instability Tool (CAIT), respectively. The analysis revealed that the scores of balance and postural stability decreased after the 6-week training for CG (p = 0.002) and SG (p = 0.001), which indicates an improvement for these variables, and the score of CAIT increased, which means the severity of instability reduced (p = 0.001 for both groups). Significant between-group differences were found for balance and postural stability (t = 2.79, p = 0.011, g = −1.99) and the severity of instability (t = 2.082, p = 0.049, g = 1.36), favoring SG compared with CG. This study showed that the addition of KT to balance training is more effective than balance training alone in improving balance, postural stability, and severity of ankle instability in female athletes with FAI. Our findings could provide a preliminary reference for designing combined balance and KT programs for delivering health benefits to females with FAI.

“…Patients with pes planus have lesser thickness and a smaller cross-sectional area of AbH and FHB than the normal person [ 28 ]. The reduced muscle thickness and smaller cross-sectional area are closely related to the reduced balance observed while standing on one foot [ 29 ]. In this study, SF had the highest FHB activity, which was significantly higher than that of the D2F exercise.…”

Background: In recent years, a three-dimensional ankle exercise has been proposed as a practice for strengthening the intrinsic foot muscles, however this topic still requires further research. This study aimed to compare the activities of the intrinsic muscles in healthy participants during 3D foot–ankle exercises, namely, short foot (SF), and toe spread out (TSO). Methods: Prior to the experiment, 16 healthy adults were trained on how to perform SF, TSO, and 3D foot–ankle exercises for an hour. Once all participants passed the foot–ankle exercise performance test, we randomly measured the activity of the intrinsic foot muscles using electromyography while the patients were performing foot–ankle exercises. Results: The abductor hallucis (AbH), extensor hallucis longus (EHL), and flexor hallucis brevis (FHB) activities showed significant differences among the exercises for intrinsic foot muscle strengthening (p < 0.01). Additionally, the AbH/AdH (adductor hallucis) ratio showed significant differences among the exercises for strengthening the intrinsic foot muscles (p < 0.01). Conclusions: Our results showed that the 3D extension exercise is as effective as the therapeutic exercise in terms of the AbH and FHB activities, and the AbH/AdH ratio. On the contrary, the 3D flexion exercise showed superiority in terms of the EHL activity.

“…Thickness and CSA values of selected tissue were measured with B-mode ultrasonography, as reported previously [ 10 , 13 ]; the aim was to measure the selected tissue in the contraction-free position using a linear array probe. The following measurements were taken in the prone position, with the subjects’ ankles in a neutral position and knees flexed at 90° to minimize pressure on the tissues while ensuring that the probe made the best contact with the skin: Thickness of the abductor hallucis (AbH), flexor hallucis brevis (FHB), and flexor digitorum brevis (FDB) muscles; CSA of AbH, FHB, and FDB, and; Thickness of the plantar fascia in the calcaneus.…”

“…Moreover, the probe was placed along a line between the second toe and the medial calcaneal tubercle to record the thickness image ( Figure 1 ). These measurements are reliable in assessing the plantar muscle and plantar fascia thickness and CSA [ 13 , 14 ].…”

The plantar fascia and intrinsic foot muscles (IFM) modulate foot stiffness. However, it is unclear whether the corresponding ultrasonography findings reflect it. This study aimed to examine the effect of the plantar fascia and IFM morphologies on force attenuation during landing and reactivity when jumping in healthy adults (n=21; age, 21–27 years). Thickness, cross-sectional area (CSA), and hardness of the plantar fascia, abductor hallucis (AbH), and flexor hallucis brevis (FHB) muscles were measured using ultrasonography. Single-leg drop landing and repetitive rebound jumping tests assessed the ground reaction force (GRF) and reactive jump index (RJI), respectively. The CSA of FHB was negatively correlated with maximum vertical GRF (r = −0.472, p=0.031) in the single-leg drop landing test. The CSA of AbH was negatively correlated with contact time (r = −0.478, p = 0.028), and the plantar fascia thickness was positively correlated with jump height (r = 0.615, p = 0.003) and RJI (r = 0.645, p = 0.002) in the repetitive bound jump test. In multivariate regression analysis, only the plantar fascia thickness was associated with RJI (β = 0.152, 95% confidence interval: 7.219-38.743, p = 0.007). The CSA of FHB may contribute to force attenuation during landing. The thickness of the plantar fascia and CSA of AbH may facilitate jumping high with minimal contact time.
