Dynamic Footprint

Static footprint parameters have been used to quantify arch height with conflicting results. This could be caused by the inherent inaccuracy and variations of the methodology used. Since the foot is a dynamic structure that undergoes changes during a step, it is more desirable to capture and analyse the dynamic footprint at an instant during the gait cycle that can most closely reflect the weight-bearing foot function. Forty (40) volunteer subjects were recruited for the reliability test of a new parameter, the Contact Force Ratio (CFR), derived from dynamic footprint. This is a measure of midfoot loading during gait. The mid-gait dynamic footprints were collected using a pressure sensing mat. Results of ICC tests showed that the CFR had good intratester (0.918) and intertester (0.909) reliability. The validity of the method was examined by correlating the parameter to the functional change in arch height, i.e. the Navicular Drop between the non-weight-bearing and weight-bearing conditions.

Acquired adult flatfoot is a three-dimensional deformation, which consists of hindfoot valgus, collapse of the longitudinal arch of the foot and adduction of the forefoot. The aim of the work is to present problems related to etiology, biomechanics, clinical diagnostics and treatment principles of acquired flatfoot. The most common cause in adults is the dysfunction of the tibialis posterior muscle, leading to the lack of blocking of the transverse tarsal joint during heel elevation. Loading the unblocked joints consequently leads to ligament failure. The clinical image is dominated by pain in the foot and tibiotarsal joint. The physical examination of the flat feet consists of: inspection, palpation, motion range assessment and dynamic force assessment. The comparable attention should be paid to the height of the foot arch, the occurrence of “too many toes” sign, evaluate the heel- rise test and correction of the flatfoot, exclude Achilles tendon contracture. The diagnosis also uses imaging tests. In elastic deformations with symptoms of posterior tibial tendonitis, non-steroidal anti-inflammatory drugs, short-term immobilization, orthotics stabilizing the medial arch of the foot are used. In rehabilitation, active exercises of the shin muscles and the feet, especially the eccentric exercises of the posterior tibial muscle, are intentional. The physiotherapy and balneotherapy treatments, in particular hydrotherapy, electrotherapy and laser therapy, are used as a support. In advanced lesions, surgical treatment may be necessary, including plastic surgery of soft tissues, tendons, as well as osteotomy procedures.

We determined the arch index of able-bodied indigenous Kenyan and Tanzanian individuals free of foot pain by using their dynamic footprints to classify the foot arch type and determine the prevalence of pes planus according to a previously described method. Males had a significantly higher arch index than females in both groups, and the prevalence of pes planus in Kenyans was 432 per 1,000 population, the highest ever documented and twice as high as that in Tanzanians (203 per 1,000 population). The arch index is useful in determining the prevalence of pes planus and possibly predicting pathologic foot conditions, and it may serve as an early warning sign of structural and functional defects of the foot in a given population.

Background: The aim of the research was to assess the longitudinal and the transverse shape of the foot arch in male and female pole vaulters. Material/Methods: The research involved 14 women and 16 men training pole vault professionally and possessing the highest level of sport’s proficiency. The assessment of the foot arch was made in static conditions, using a podoscope. The longitudinal foot arch was assessed by Clarke’s method and the transverse foot arch was based on the calcaneal angle. Results: The obtained results showed that the correct and excessive foot arch occur most frequently. Conclusions: Numerous technical exercises performed by pole vaulters on the forefoot and toes strengthen the foot (shortening muscles responsible for a proper level of the longitudinal and the transverse foot arch) and result in the correct or excessive arch in the right and the left foot.

Arch Index

Flatfoot (pes planus), commonest foot deformity caused by the absence or collapse of the medial longitudinal arch. Flatfoot results in serious health problems and postural defects. It is highly variable in different populations with many factors associated. This study was conducted to find the plantar arch index and the prevalence of flatfoot and its relationship with tribes in Ghana. A total of 278 participants (172 males and 106 females) with ages ranging from 16 to 34 years were recruited for the study. Ethical approval and participants’ informed consent were sought prior to the study. Participants were drawn from the Akan, Ewe, Ga-Dangbe and other tribes (Dagomba, Dagabaa, Frafra, Gonja, Wale Wale etc). Foot imprints were taken from each participant using the ink method. The plantar arch index was calculated using the ratio of the width of the central and the heel region of the footprint. The mean right plantar arch index was higher than the left. The prevalence of flatfoot was 15.1% (6.1% unilateral left, 5.8% unilateral right and 3.2% bilateral). The prevalence rate was 15.7% in males and 14.1% in females. The prevalence rates reported for the Ga-Dangbes and Ewes were 30.8% and 23.6% respectively. On the other hand, both Akans and individuals belonging to the other tribes recorded the same prevalence rate of 13.7%. Flatfoot was found to be high among the Ga-Dangbes. Ethnicity as an external factor has a great role in influencing foot arch structure. Also, sex has an influence on the morphology of an individual’s foot.
