The purpose of this current study was to measure the knee joint angle and plantar pressure distribution between hallux valgus group and normal group under jogging condition. To reveal relationship of plantar pressure distribution and knee joint angle. Investigated that lower extremity mechanics of jogging in young female with mild hallux valgus. Sixteen young, healthy females volunteered to take part in this study. Kinematic data from a three-dimensional motion analysis system and plantar pressure distribution from Pedar-X system were collected to describe lower extremity mechanics while hallux valgus subjects jogging at a natural speed. The results found that knee joint angle of hallux valgus in frontal and transverse plane was obviously different under jogging condition. In frontal plane, the initial state of adduction angle (control group (CO) = 1.73 °, hallux valgus group (HV) = 8.33 °) of two group was markedly different at the beginning of the support (0-10%). During jogging gait cycle, knee abduction angle peak of normal group was 8.46°, and knee adduction angle peak of hallux valgus group was 8.61°. In the transverse plane, knee external rotation angle in the initial state of normal group was 21.93° while knee external rotation angle of hallux valgus was 4.89°. The results of plantar pressure found that bearing pressure regions was offshore in hallux valgus group. These changes would affect the movement of knee joint, and it suggested that hallux valgus group have higher risk for knee osteoarthritis. These results also suggested that hallux valgus deformity has influence on knee joint. We cannot be ignored in the process of the research and therapeutic with hallux valgus.

Background:Higher plantar pressures at the medial forefoot are reported in hallux valgus. Foot orthoses with medial arch support are considered as an intervention in this pathology. However, little is known about the effect of foot orthoses on plantar pressure distribution in hallux valgus.Objectives:To investigate the effect of a foot orthosis with medial arch support on pressure distribution in females with mild-to-moderate hallux valgus.Study design:Quasi-experimental.Methods:Sixteen female volunteers with mild-to-moderate hallux valgus participated in this study and used a medial arch support foot orthosis for 4 weeks. Plantar pressure for each participant was assessed using the Pedar-X®in-shoe system in four conditions including shoe-only and foot orthosis before and after the intervention.Results:The use of the foot orthosis for 1 month led to a decrease in peak pressure and maximum force under the hallux, first metatarsal, and metatarsals 3–5 ( p < 0.05). In the medial midfoot region, peak pressure, maximum force, and contact area were significantly higher with the foot orthosis than shoe-only before and after the intervention ( p = 0.00).Conclusion:A foot orthosis with medial arch support could reduce pressure beneath the hallux and the first metatarsal head by transferring the load to the other regions. It would appear that this type of foot orthosis can be an effective method of intervention in this pathology.Clinical relevanceFindings of this study will improve the clinical knowledge about the effect of the medial arch support foot orthosis used on plantar pressure distribution in hallux valgus pathology.

Background: Proximal crescentic osteotomy (PCO) in patients with moderate-to-severe hallux valgus (HV) is a well-established and effective procedure for correcting the deformity. However, there are no published studies comparing plantar pressure in postoperative HV feet with healthy feet. This study aimed to compare the plantar pressure distribution in postoperative HV feet with healthy feet. Methods: Twenty-six patients were included in the HV group, and 24 healthy participants were included in the control (C) group. All patients in the HV group underwent unilateral PCO. After undergoing PCO, this group was defined as the OP group. All subjects were women with no significant differences in age, height, weight, and body mass index. There were no significant differences in demographic characteristics between patients in each group. We divided the subjects’ feet into 8 regions and measured the peak pressure (Peak-P), maximum force (Max-F), contact time, contact area, and the force-time integral in each region. Results: All parameters of the great toe were significantly higher in the OP group than in the HV group. All forefoot parameters were not significantly different between the 2 groups. No parameter of the great toe was significantly different between the OP and C groups. However, mean Peak-P and Max-F of the central forefoot were significantly higher in the OP group than in the C group. Conclusion: PCO can improve the plantar pressure of the great toe in patients with moderate-to-severe HV to a level similar to that in healthy subjects. Level of Evidence: Level III, comparative study.

The quantification of plantar pressure distribution is widely done in the diagnosis of lower limbs deformities, gait analysis, footwear design, and sport applications. To date, a number of pressure insole layouts have been proposed, with different configurations according to their applications. The goal of this study is to assess the validity of a 16-sensors (1.5 × 1.5 cm) pressure insole to detect plantar pressure distribution during different tasks in the clinic and sport domains. The data of 39 healthy adults, acquired with a Pedar-X® system (Novel GmbH, Munich, Germany) during walking, weight lifting, and drop landing, were used to simulate the insole. The sensors were distributed by considering the location of the peak pressure on all trials: 4 on the hindfoot, 3 on the midfoot, and 9 on the forefoot. The following variables were computed with both systems and compared by estimating the Root Mean Square Error (RMSE): Peak/Mean Pressure, Ground Reaction Force (GRF), Center of Pressure (COP), the distance between COP and the origin, the Contact Area. The lowest (0.61%) and highest (82.4%) RMSE values were detected during gait on the medial-lateral COP and the GRF, respectively. This approach could be used for testing different layouts on various applications prior to production.
