Summary: This study compares the influence of increased metatarsophalangeal (MTP) joint dorsiflexion and added mass on foot arch rigidity. The results show that both increased MTP joint dorsiflexion and added mass increase midtarsal joint quasi-stiffness. It is also found that foot arch rigidity can be actively modulated, and a more rigid foot does not necessarily transfer power to the ground more efficiently.

Summary: This study aims to assess how foot posture and morphology assessments change according to body mass index (BMI) status and determine which body composition parameter correlates better with foot measures in children. The study found that foot morphology differs among BMI categories in children, with waist circumference (WC) correlating better with foot measures than BMI. Additionally, the midfoot width (MFW) is the foot measure best explained by children's body weight. This has implications for footwear manufacturers and suggests the need for shoes with different patterns and a system to adjust midfoot height.

Summary: This study used a high-speed dual fluoroscopic imaging system (DFIS) to investigate the motion of the medial longitudinal arch (MLA), first metatarsophalangeal joint (MTPJ), and plantar fascia (PF) during running, and examined the effects of forefoot strike (FFS) on the kinematics of these structures. The results showed that FFS significantly increased the range of motion of the MLA and first MTPJ, as well as the strain and power of the PF.

Summary: Long-distance running can cause a decrease in foot arch height and increase in asymmetry, as observed in collegiate runners who completed a full marathon. Factors such as pre-race foot arch asymmetry were found to predict post-race asymmetry and displacement of navicular height. Overall, full marathon running induced increased asymmetry and lowered the medial longitudinal arch in runners.

Summary: This study aimed to investigate the relationship between plantar aponeurosis stiffness and medial longitudinal arch stiffness. The results showed that there was no significant correlation between shear wave velocity of the plantar aponeurosis and medial longitudinal arch stiffness, suggesting that the latter is more influenced by other foot structures.

Summary: Diabetes is a leading cause of death in the United States, with African Americans (AA) being twice as likely to die from diabetes compared to White Americans (WA). AA are also twice as likely to experience foot amputation due to foot ulcers caused by high plantar pressure. This study found that race, along with other variables, can significantly predict plantar loading.

Summary: This study evaluated the biomechanical effects and pain relief of combining lateral wedge foot orthoses with two types of knee brace for patients with medial knee osteoarthritis. The results showed that the valgus and external rotation brace reduced knee adduction moment and increased knee flexion while maintaining comfort. The combined treatment with foot orthoses enhanced the effectiveness of the valgus brace.

Summary: This study reports a novel anomalous intrinsic foot muscle located on the medial arch of a 78-year-old white male cadaver. The muscle consisted of two slips crossing the plantar aspect of the medial arch, suggesting a possible location for medial nerve entrapment.

Summary: This study explored the application value of 3D scanning in obtaining the parameters of the transverse axis of the medial longitudinal arch of the foot for biomechanical evaluation in children. The scanning data were used to measure four parameters, including transverse arch angle, external transverse arch angle, curvature, and transverse arch cross-sectional area. The results showed significant differences in these parameters between sitting and standing positions, as well as among children with different foot types. Therefore, the four parameters obtained through three-dimensional scanning can effectively evaluate the transverse axis of children's foot arch.

Summary: This study examined the relationship between changes in foot characteristics and sex differences during the menstrual cycle in healthy male and female university students. The results showed that females had a significantly lower arch height index (AHI) than males in the early follicular and ovulatory phases, but there was no significant difference in AHI between males and females in each phase. Additionally, there was no significant difference in arch height flexibility (AHF) between males and females in each phase, suggesting that sex differences in AHF may be absent.

Summary: An 89-year-old male presented with severe untreatable pain and ischemic non-healing ulcer in the left forefoot. The pre-procedural angiograms showed multiple stenosis of the arteries, which were successfully treated with recanalization and balloon angioplasty. The patient's condition improved after the intervention.

Summary: This study assessed various methods of medial longitudinal arch (MLA) assessment using motion capture of surface markers. The best method utilized markers of the first metatarsal head, fifth metatarsal base, navicular, and heel. This study aligns with current literature recommendations for the use of a navicular marker to characterize the MLA and advocates against the use of projected markers in most situations.

Summary: This study aimed to investigate the challenge posed by progressively unstable balance devices to bipedal stance during early functional rehabilitation in THA patients. The results showed that increasingly compliant balance pads provided a progressive challenge, while the challenge posed by the oscillating platform was lower and independent of the ability to stand independently.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This study investigated the differences in lumbar and hip movements during gait and muscle activities related to knee osteoarthritis (KOA) patients and healthy participants. The results showed that KOA patients used a hyperlordotic lumbar and hip flexed strategy, leading to excessive stress on the lower extremity joints during gait.

Summary: This study investigated sex differences in lower limb dynamic joint stiffness (DJS) during walking in older adults. The results showed that ankle DJS was lower in older women, which was caused by the reduced ankle plantarflexion moment. However, knee DJS did not elucidate the cause of knee osteoarthritis (OA) in older women.

Summary: The study found that the reliability of stiffness, viscosity, and inertia of the ankle joint was good to excellent during standing. During walking, the reliability of stiffness and viscosity was also good to excellent, while that of inertia was fair to good. The minimal detectable change (MDC) ranged widely, but was higher for inertia during walking.

Summary: This study investigates the effects of footwear type, navicular drop and ankle pronation on lower limb joint stiffness during running. The results show that navicular drop and dynamic ankle pronation do not affect joint stiffness, but footwear type significantly affects joint stiffness. Conventional footwear increases ankle and hip joint stiffness while reducing knee joint stiffness, which may have implications for injury risk.

Summary: This systematic review is the first to compile evidence on the effect of the menstrual cycle on postural control. The evidence regarding the influence of the menstrual cycle on postural control is unclear. However, a trend of decreased postural control from the early follicular phase to the ovulatory phase was observed in balance tasks that eliminated or altered sensory input.
