“…Our results also showed a greater subtalar angle in the PFP group compared to the control group. Similar results were reported by the research of Dileep et al 21 , in which the patients with PFP within the ages of 20-30 years were evaluated according to their foot posture and PFP syndrome and found an association between these two components. In contrast to our study, Hetsroni et al 22 concluded that there is no consistent association between the incidence of anterior knee pain and foot pronation by measuring the subtalar joint displacement angle.…”

Objective: It has been theorized that changes in the lower extremity mechanics may lead to develop Patellofemoral Pain (PFP) in the young population. The present study aims to investigate the effects of lower extremity mechanics on Patellofemoral Pain Syndrome in private university students. Material and Methods: Kujala Pain Score (KPS) of 400 Yeditepe University students ages of 18-30 years was performed. Students having a less or equal point of 85 in KPS (n=30) and healthy groups randomly selected in students with KPS=100 (n=30) were measured in terms of Feiss Line, navicular drop, subtalar angle, tibial torsion, knee valgus angle, Q angle in standing and supine position and hamstring tightness. Results: The prevalence of PFP among students was found to be 10.5%(n = 42). In case and control groups were found 2nd Pes Planus (PP) as 16 (%53,3) and 3 (%10) respectively. A statistically significant difference was found between groups in navicular drop, subtalar angle, tibial rotation, Q angle in supine and hamstring tightness (p-value

“…The CTA, which has natural relation with tibial rotational alignment was expected to be correlated with QA. This expectation may originate from the studies previously demonstrating the relationship between rearfoot position and QA in conditions like patellofemoral pain syndrome 28 . In the current study with asymptomatic participants, however, the CTA was surprisingly not represented in the final regression model either alone or in combination with other predictors.…”

Objective The aim of study was to analyze the association between Quadriceps Angle (QA) and plantar pressure, navicular height (NH), and calcaneo-tibial angle (CTA). Methods A total of 64 volunteers (mean age: 22.25 ± 2.54 (range:19–33)) participated in this cross sectional study. EMED-m (Novel GmbH, Germany) electronic pedobarograph was employed for dynamic plantar pressure measurement using two step protocol. The angle between the vertical axis of calcaneus and the long axis of Achilles tendon for CTA. The height of navicular tubercle from the ground was measured while the subject was standing on both feet for NH. QA was measured while the subject was standing in a relaxed posture where both feet bearing equal weight. Results There were significant negative correlations between QA and maximum force (MxF) under the 4th. metatarsal head (MH4). The QA was also significantly correlated with MxF and force-time integral (FTI) under the bigtoe (BT). FTI under the 3rd. metatarsal head (MH3), MH4 and 5th. metatarsal head (MH5) were significantly negatively correlated with QA. Pressure-time integral (PTI) under the MH4 and MH5 were found to be significantly negatively correlated with QA. A significant correlation was also found between QA and NH (p < 0.0001), whilst there was no correlation between QA and CTA. Regression analysis showed that NH was appeared as the major contributor for the QA (β = −0.49, p < 0.001) in the dynamic condition, followed by BT-FTI (β = 0.37, p < 0.001) and MH5-MxF (β = −0.21, p < 0.037). Conclusion These findings may imply that the NH which can at least be controlled by appropriate shoe inserts may affect QA. This way, loading pattern of both plantar region and whole lower extremity may be altered. Level of evidence Level III, Diagnostic Study.

“…Another previous study reported that rearfoot misalignment causes compensatory action of the subtalar joint, which is involved in the normal function of the leg and foot during the gait cycle. Furthermore, excessive pronation of the subtalar joint inhibits foot supination and results in abnormal internal rotation of the tibia, which leads to patellar malalignment [ 28 ]. Among taekwondo athletes, sparring athletes perform kicking techniques using ground reaction force with the forefoot for the longest period of time, and forefoot pronation occurs rapidly and repeatedly, especially in situations such as maintaining distance, changing direction, and continuing skills.…”

Background and Objectives: Studies analyzing lower extremity alignment (LEA) LEA among taekwondo subdisciplines athletes are lacking. This study compared LEA in the dominant and nondominant legs intaekwondo athletes. Materials and Methods: Twelve measurements of LEA were analyzed for 157 athletes (63 sparring, 50 demonstration, and 44 poomsae athletes) registered with the Korea Taekwondo Association. LEA was measured in the standing, supine, and prone positions using alignment application, a goniometer, a bubble inclinometer, a height gage, and a palpation meter. Results: The analysis revealed that the dominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring athletes (p < 0.01), whereas the dominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). Furthermore, the nondominant leg of poomsae athletes showed greater genu valgum alignment than that of sparring and demonstration athletes (p < 0.01), whereas the nondominant leg of sparring athletes showed greater rearfoot varum alignment than that of demonstration athletes (p < 0.01). In addition, demonstration athletes had better forefoot varus alignment than poomsae athletes (p < 0.01). Conclusions: This study revealed that LEA characteristics vary among taekwondo athletes according to their subdiscipline. The results of this study would help in designing training programs tailored to each subdiscipline that would best address their LEA characteristics and help to prevent injuries.
