“…The function of the arch-support insole is thought to help restore the elasticity of the foot arch [ 41 ] for people with flatfoot, thereby reducing the foot pronation during uphill, downhill and level walking. The reduced medial heel peak pressure in the arch-support insole was speculated to reduce the heel striking impact and further facilitate the transfer of loading to improve stability and comfort [ 42 ] that would benefit people with flatfoot.…”

Background Pes planus (flatfoot) is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries such as thumb valgus, tendinitis, plantar fasciitis, metatarsal pain, knee pain, lower-back pain with prolonged uphill, downhill, and level walking, depriving them of the physical and mental health benefits of walking as an exercise. Methods Fifteen female college students with flatfoot were recruited. A wireless plantar-pressure system was used to measure the stance time, cadence, plantar pressure, and contact area. Parameters were compared between wearing flat and arch-support insoles using a two-way repeated measures ANOVA with on an incline, decline, and level surface, respectively. The significance level α was set to 0.05. The effect size (ES) was calculated as a measure of the practical relevance of the significance using Cohen’s d . Results On the level surface, the stance time in the arch-support insole was significantly shorter than in the flat insole ( p <0.05; ES = 0.48). The peak pressure of the big toe in the arch-support insole was significantly greater than in the flat insole on the uphill ( p <0.05; ES = 0.53) and level surfaces ( p <0.05; ES = 0.71). The peak pressure of the metatarsals 2–4 and the contact area of the midfoot in the arch-support insole were significantly greater than in the flat insole on all surfaces (all p < 0.05). Conclusions These results imply that wearing an arch-support insole provides benefits in the shortened stance time and generation of propulsion force to the big toe while walking on uphill and level surfaces and to the metatarsals 2–4 while walking on the level surface. More evenly distributed contact areas across the midfoot may help absorb shock during uphill, downhill and level walking.

“…An arch is the most pressure sensitive region of the foot. Adding an arch support to custom foot orthoses or footwear can improve the stability for individuals with high-arched feet during walking [35].…”

“…The fundamental objectives of the optimize design of a heel lift or high-heeled are reducing the plantar load and improving performance. A well-designed arch support can not only reduce peak force of the forefoot but also improve stability control [29,35,37]. The AP-COP displacements and the regularity of AP-COP velocity during forefoot contact phase can be used to optimize and assess the design of the heel lift or high-heeled shoe.…”

Background: The medial longitudinal arch height has an effect on kinetic parameters during gait and might be related to the risk of injury. For the assessment of foot structures, the center of pressure (COP) trajectory is a more reliable and practical parameter than plantar pressure. This study aimed to clarify the COP trajectory and velocity characteristics in the medial-lateral and anterior-posterior direction of individuals with a high-arched foot during barefoot walking. Methods: Sixty-two healthy young adults were asked to walk over a Footscan pressure plate to record the COP parameters during the stance phase of walking. Results: Compared to normal arched feet, the COP during forefoot contact and foot flat phases of high-arched feet shifted anteriorly (19.9 mm and 15.1 mm, respectively), and the mean velocity of COP in anterior-posterior direction decreased by 0.26 m/s and increased by 0.044 m/s during these two phases respectively. Conclusions: The findings of this study suggest that the displacement and velocity of COP in anterior-posterior direction was different between high-arched and normal-arched subjects during barefoot walking, which can be used for the assessment of gait characteristics for high-arched individuals. The results of this study may provide insights into modifying clinical intervention for individuals with high-arched feet to enhance rehabilitation and prevent injuries and have implications for assessing the design of footwear and foot orthotics.

“…Maximal pressure, maximal force and contact area were measured to evaluate the variability of plantar pressure distribution during two types of gait termination experiments. Previous studies [27], [28] have shown that the displacement of the medial-lateral center of pressure (ML-COP) could be used to assess the medial-lateral stability, especially during the forefoot contact phase and the foot flat phase. Therefore, we calculated the range of the ML-COP trajectory by comparing the absolute difference between the largest and smallest coordinate of the COP respectively during these phases.…”

“…To the best of our knowledge, at present, studies about UGT mainly focus on kinematics, while kinetics studies are limited to the joint moment of lower limbs. Plantar pressure data have been validated by previous studies as an indicator of human stability in different populations and under different conditions [22], [27], [29]. However, there is no relevant plantar pressure study about UGT, and no direct study has compared differences of plantar loading distribution during two types of gait stop and conducted to ascertain whether better lower limbs muscle strength level can lead better stability.…”

Unplanned gait termination (UGT) widely occurs in various sports and daily life as a kind of stress response to unexpected stimulus. However, the body stability may be greatly affected when the body completely stops. The purpose of this study was to examine the association between muscle strength levels and body stability during UGT through comparing the plantar pressure. Methods: Twenty healthy participants (10 male and 10 female) with different lower limbs muscle strength and power were asked to perform planned gait termination (PGT) and unplanned gait termination (UGT) on an 8-m walkway. Related plantar pressure data including maximum pressure, maximum force, contact area and center of pressure were recorded with Footscan pressure platform. Results: Two types of gait termination have significant differences in the plantar pressure distribution. Maximum pressure and maximum force in the lateral metatarsal increased significantly during UGT, compared to PGT. At the same time, data from the current study suggested that there might be a correlation between the muscle strength levels of individual and the stability during the gait termination, especially between the muscle power and UGT, which means that the more excellent muscle power an individual has, the more stable the body is when UGT is performed. Conclusions: The findings suggest that different muscle strength levels could affect stability during unplanned gait termination.
