“…Clarke's Angle (CA) index: CA index is measured by estimating the angle of a first medial tangential line that joins the medial edges of the first metatarsal head and the heel, and a second line that joins the first metatarsal head and the top of MLA concavity [18] (Figure 1). Based on this index, FF is present if the calculated number is <41º [19].…”

The present study investigated the most appropriate footprint index and its related parameters for the diagnosis of flatfoot, especially in cases with mild deformity. Methods: In total, 148 footprints were recorded from 77 young women with flatfoot. Footprints were classified into three groups of mild, moderate, and sever. Footprint indexes included Sztriter-Godunov (KY), Clarke's Angle (CA), Chippaux-Smirak Index (CSI), and Staheli (ST) indexes. The mentioned indexes and their relevant parameters were calculated on the footprints in the aforementioned groups. Exploratory factor analysis was used to identify proper components for the diagnosis of flatfoot. By multivariate analysis of variance, between-group differences were assessed. A Chi-squared test was used to identify the most accurate index for the diagnosis of mild flatfoot. Results: Exploratory factor analysis based on the parameters of footprint indexes identified three essential components. Two identified components were based on the 6 parameters of CSI, KY, and ST indexes in moderate and sever footprints. The third component was related to footprints with mild grading and was composed of three extracted parameters from midfoot region. Moreover, the linear combination of the three last parameters suggested a significant difference between three groups (P<0.01). Eventually, KY index could identify the highest number of flatfoots in the mild group (P=0.000). Conclusion: Study findings revealed that indexes in which parameters were extracted from midfoot region could be suitable for the diagnosis of mild flatfoot. KY index's parameters were extracted from midfoot. Considering that KY could identify several remarkable mild flatfoots in comparison with other indexes, we can introduce it as a proper index.

“…The direct factor that determines the cushioning effect is the shape of the foot arch. Generally, the arch mainly includes three types: high arch feet, flat feet and normal feet [8][9][10]. A high arch foot is usually caused by an increase in the longitudinal arch of the front foot.…”

“…The arch index based on the arch height is obtained by the ratio of the arch height to the foot length. The arch index based on the pressure area is obtained from the ratio of the arch area to the whole foot area (excluding the toes), and the arch index based on arch width is obtained by the ratio of the arch width to the foot length [8,11,[26][27][28]. The calculation method used in this work is the ratio of foot arch pressure area to the whole foot area (excluding the toes).…”

The foot arch index is an important index to evaluate the health of human feet and the biomechanics line, aiming at addressing the shortcomings of the low efficiency and slow speed of manual foot arch index measurement; in this work, an automatic foot arch index measurement method based on a flexible membrane pressure sensor was proposed. The distribution of plantar pressure data was obtained from the flexible membrane pressure sensor and converted into a digital image. The 8-neighborhood correlation pixel method was proposed to remove the interference of isolated noise points. In order to remove the toes’ data without affecting the foot sole data, the row element association algorithm was proposed. The front and back endpoints of the foot were automatically located to obtain the foot length, and the foot arch index was also automatically obtained based on the foot arch pressure area. Whether it was a high arch foot, flat foot or normal foot, the method proposed in this paper could accurately and quickly distinguish them. The prototype was developed, and its feasibility and validity were verified by a series of tests.

Flat foot pain is a common complaint that requires therapeutic intervention. Currently, myofascial release techniques are often used in the therapy of musculoskeletal disorders. A group of 60 people suffering from flat feet with associated pain. Patients were assigned to four groups (15 people each): MF—myofascial release, E—the exercise program, MFE—myofascial release and the exercise program, C—no intervention. The rehabilitation program lasted 4 weeks. The NRS scale was used to examine pain intensity and FreeMed ground reaction force platform was used to examine selected static and dynamic foot indicators. Statistically significant pain reduction was obtained in all research. A static test of foot load distribution produced statistically significant changes only for selected indicators. In the dynamic test, statistically significant changes were observed for selected indicators, only in the groups subjected to therapeutic intervention. Most such changes were observed in the MF group. In the dynamic test which assessed the support phase of the foot, statistically significant changes were observed only for selected subphases. Most such changes were observed in the MFE group. Both exercise and exercise combined with myofascial release techniques, and especially myofascial release techniques alone, significantly reduce pain in a flat foot. This study shows a limited influence of both exercises and myofascial release techniques on selected static and dynamic indicators of a flat foot.
