“…However, we found no changes in muscle morphology, indicating that changes in passive ankle ROM during gait were not because of morphological changes in the GM. This finding is also supported by recent studies of Pothrat et al and Kalkman et al in which changes in φ FoSo did not correspond to length changes of the triceps surae muscles …”

“…During passive ankle ROM assessment with a maximally externally applied 4 Nm dorsiflexion footplate moment, almost half of the φ FoSo ROM was accounted for by flexion within the foot. Therefore, it is expected that during gait, when much higher loads are imposed, foot flexibility will explain a substantial fraction of φ FoSo change . Altogether, our findings question whether the treatment goal of increasing ankle ROM in this case was achieved.…”

“…This finding is also supported by recent studies of Pothrat et al and Kalkman et al in which changes in φ FoSo did not correspond to length changes of the triceps surae muscles. 29,30 Instead, it is likely that increased foot flexibility contributed to observed changes in gait. Using a simple approach, we showed that flexibility of the foot greatly contributed to apparent ankle ROM, especially at 9 wk post-treatment.…”

Comprehensive instrumented muscle and joint assessments should be considered when prescribing Botulinum NeuroToxin‐A (BoNT‐A) treatment in spastic paresis. In a child with spastic paresis, comprehensive evaluation following treatment with BoNT‐A, serial casting, and physiotherapy showed that short‐term improvements in gait occurred without changes in muscle morphology. Rather, foot flexibility increased.

“…In addition, Pothrat et al found that use of a MFM compared to a SFM produced different ankle kinematics during gait. Specifically, these authors reported greater ankle dorsiflexion angles and lower varus angles in the SFM than in the MFM . Furthermore, Dixon et al showed that an SFM significantly overestimated the maximum power and angular velocity of the ankle joint compared with an MFM during normal gait, which led them to recommend the use of MFM when making decisions for surgical interventions.…”

Multi‐segment foot models (MFMs) are becoming a common tool in musculoskeletal research on the ankle‐foot complex. The purpose of this study was to compare ankle joint kinematics as well as ligament and muscle strains that result from MFM with a different number of segments during vertical hopping. Ten participants were recruited and performed double‐limb vertical hops. Marker positions and ground reaction forces were collected. Two‐segment (2MFM), three‐segment (3MFM), and five‐segment MFM (5MFM) were used to calculate ankle kinematics and the strains of the anterior talofibular and calcaneofibular ligaments and of the soleus and gastrocnemius muscles. Ranges of motion and peak strains were analyzed with Kruskal–Wallis and post hoc tests, whereas the time‐series of the ankle kinematics and ligament and muscle strains were analyzed with statistical parametric mapping. There were significant main effects for MFM in the talocrural joint range of motion and peak strains of ligaments and muscles. In addition, there were significant main effects for MFM in time‐series data of the talocrural joint angle as well as for ligament and muscle strains. In all cases, the post hoc analyses showed that the 2MFM consistently overestimated the range of motion and tissue strains compared to the 3MFM and 5MFM, while 3MFM and 5MFM did not differ from each other in the most variables. This study showed that the number of segments in MFM significantly affects the biomechanical estimates of joint kinematics and tissue strains during hopping. Clinical significance: MFM that combine all foot structures beyond the talus into one segment likely overestimate ankle joint biomechanics. © 2019 Orthopaedic Research Society.

“…In conditions of natural locomotion foot serves as support and ensures organization of spring interactions of human body with surface. It means that in foot motor mechanisms great potentials of spring-ductile properties of the whole lower limb are embedded [1,5,11,12,[28][29][30][31].…”

Abstract. Purpose: to fulfill comparative analysis of foot support-spring indicators of schoolchildren with weak eyesight. Material: in the research 7-10 years' age children (n=76) with weak eyesight participated. The children learn in specialized boarding school. Results: we found statistically confident differences between some foot support-spring indicators of primary school children with weak eyesight and their practically healthy children. It was registered that primary school children had weaker muscles and ligaments of lower limbs. The reason can be insufficient motor functioning and muscles' stiffening in moving in space as well as the absence of exercises for prophylaxis of foot functional disorders. Conclusions: we determined that there is demand in working out and implementation of practical recommendations in physical education process of schoolchildren with weak eyesight. Physical education process shall be oriented on educational aims, on application of health related correcting and compensatory-prophylaxis physical exercises. Such approach will positively influence on correction of foot support-spring disorders.
