“…OOT progression angle (FPA) is a critical walking gait parameter for disease assessment and rehabilitation. It is a clinical measure to assess cerebral palsy [1], [2], distal tibial physeal fractures [3], and gastrocnemius inflexibility [4]. Also, FPA modification is a potential gait rehabilitation alternative for knee osteoarthritis patients because it can reduce the peak knee adduction moment [5]- [7] and reduce knee pain [8], [9].…”

“…Also, the limitations of cruciate-collateral ligaments and quadriceps femoris on knee motion result in the knee joint self-locking as an eccentric wheel to maintain the stability of the joint during the knee extension motion [8]. Regarding the importance of the external moment of the knee, Wu et al [20] stated that abnormal external rota-tion of the knee during the stance phase is a common cause of lateral deviation of the patella in people with gastrocsoleus complex shortness, which is a known risk factor for patellofemoral pain. In this regard, according to the findings of this study, functional stretching of the gastroc-soleus muscle complex may be effective (Fig.…”

“…Previous studies showed that restricted ankle DF leads to mechanical changes of the lower extremity joints in the kinetic chain [19]. With regard to the importance of the external moment of the knee, abnormal external rotation of the knee during the stance phase is a common cause of lateral deviation of the patella in people with gastroc-soleus complex shortness, which is a known risk factor for patellofemoral pain [20]. Therefore, after identifying the underlying causes of lower extremity injuries in athletes (external knee rotation), it is necessary to emphasize those training programs focused on reducing the rotational moment.…”

Background and objective: Tightness of the gastroc--soleus muscle complex is one of the limiting factors of the ankle joint's range of motion (ROM) during daily activities. The aim of this study was to investigate the effectiveness of functional and extra-functional stretching of the gastrocnemius--soleus complex on knee joint loading in athletes with limited ankle dorsiﬂexion. Material and methods: In this cross-sectional study, 30 male athletes with gastrocnemius--soleus shortness were recruited and randomly divided into three equal-size groups of functional stretching, extra-functional stretching, and a control group. The extra-functional stretching group performed stretching exercises three times per day for eight weeks. The functional stretching group was instructed to change their gait pattern via increased heel strike during daily activities. Results: None of the stretching programs reduced the knee ﬂexion angle in heel contact (p > 0.05). The knee ﬂexion angle was signiﬁcantly increased in the stance phase in the functional group (p ≤ 0.05). Walking speed was increased signiﬁcantly in the extra-functional group (p ≤ 0.05). The knee adductor moment and external rotation moment decreased signiﬁcantly in the functional group (p ≤ 0.05). Conclusion: An eight-week functional stretching program in this study led to a reduction of knee loading in the frontal and horizontal planes in comparison to the extra-functional stretching group, demonstrating the effectiveness of functional stretching in improving knee joint biomechanics during walking.

“…Furthermore, the effect of gastrocnemius muscle flexibility on foot angle has also been reported. In particular, low gastrocnemius muscle flexibility was found to result in greater foot angle [21]. Therefore, it is necessary to take into account that structural factors, such as bone shape and muscle flexibility, influence foot angle as well as the strategy towards achieving gait stability.…”

The gait parameters of the older adults are closely related to balance function. However, there have been no studies in which the relationship between gait parameters and frequently used balance tests, such as CoP excursion and Mini-Balance Evaluation Systems Test, were investigated with a focus on the frontal plane. Therefore, the purpose of this study is to elucidate the relationship between frontal-plane gait parameters and balance tests in older adults. Eighteen older adults who attended health classes participated in the study.Step length, step width, and foot angle were measured at a normal walking speed and maximum walking speed, using a sheet-like force plate. To assess postural balance, we measured center of pressure excursion and administered a Mini-Balance Evaluation Systems Test. As a result, no correlation between step width/foot angle and age or postural balance was observed. Moreover, step width and foot angle did not change at different walking speeds. In conclusion, step width and foot angle are not affected by postural balance in healthy older adults. Rather, step width and foot angle may be determined by gait efficiency and structural factors.
