Background and aim: In the perimenopausal period, changes in balance and postural control have been reported. We aimed to invastigate the effect of medial longitudinal arch height and medial arch-support insoles on postural sway and balance in middle aged women in perimenopausal period. Materials and Methods: 29 women with normal arches and 29 women with low arches were included in the study. Foot arch of the participants was determined by "arch height index". The static balance index (SBI) measured by Kinesthetic Ability Trainer 3000 and Functional Reach Test were used to evaluate postural balance. Measurements were obtained from all participants with and without medial arch-support insoles. Results: The SBI-total scores without the insoles were found to be significantly higher in the lower arch group than the normal arch group. SBI-total, SBI-anteroposterior, and SBI-mediolateral scores significantly improved in the low arch group in the presence of insoles, whereas the usage of insoles resulted in no difference in the normal arch group. In the presence of insoles, the reach distances to left and right sides increased in both groups, while the forward functional reach distances decreased. Conclusion: Medial longitudinal arch height and medial arch-support insoles affect the balance parameters in perimenopausal women.

Background: Measurement of the medial longitudinal foot arch in children is a controversial topic, as there are many different methods without a definite standard procedure. The purpose of this study was to 1) investigate intraday and interrater reliability regarding dynamic arch index and static arch height, 2) explore the correlation between both arch indices, and 3) examine the variation of the medial longitudinal arch at two different times of the day. Methods: Eighty-six children (mean ± SD age, 8.9 ± 1.9 years) participated in the study. Dynamic footprint data were captured with a pedobarographic platform. For static arch measurements, a specially constructed caliper was used to assess heel-to-toe length and dorsum height. A mixed model was established to determine reliability and variation. Results: Reliability was found to be excellent for the static arch height index in sitting (intraday, 0.90; interrater, 0.80) and standing positions (0.88 and 0.85) and for the dynamic arch index (both 1.00). There was poor correlation between static and dynamic assessment of the medial longitudinal arch (standing dynamic arch index, r = –0.138; sitting dynamic arch index, r = –0.070). Static measurements were found to be significantly influenced by the time of day (P < .001), whereas the dynamic arch index was unchanged (P = .845). This study revealed some further important findings. The static arch height index is influenced by gender (P = .004), whereas dynamic arch index is influenced by side (P = .011) and body mass index (P < .001). Conclusions: Dynamic and static foot measurements are reliable for medial longitudinal foot arch assessment in children. The variation of static arch measurements during the day has to be kept in mind. For clinical purposes, static and dynamic arch data should be interpreted separately.

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.

AbstractThe paper details the morphological adaptations of the foot shape and its arches to sustained professional tree climbing activity. Foot inversion, as required by climbers on a long term and regular basis reshapes the bony architecture of the foot and the medial longitudinal arch over a period of time. These changes can be observed and measured, noninvasively through study of footprints.This community study on the progressive adaptation of the arch to the rigors of climbing was recorded through footprints collected from the climbers with varied experience in the profession. The collation of observations show that the medial arch continues to shrink with sustained inversion, raising the dome of the instep.The progressive compensatory rise in arch height however, is arrested abruptly after a phase, with failure of the arch to accommodate further to more stress – leading to slipping and falls from heights. The article discusses the bio-mechanisms and kinetics of foot adaptation to the rigors of climbers and analysis the cause of accidental falls, even though most of the accidental fall victims have had a number of years of climbing experience.

A study was conducted to determine whether plantar surface contact area measures calculated from footprints collected during walking can be used to predict the height of the medial longitudinal arch. Thirty healthy women participated in the study. Arch height was determined by the distance from the navicular tuberosity to the floor and by the “bony” arch index. Dynamic plantar surface contact area was recorded using a pressure platform as the subjects walked across a 12-m walkway. The arch index and the total plantar surface contact area were determined from the pressure sensor data. The results indicated that plantar surface contact area could be used to estimate only approximately 27% of the height of the medial longitudinal arch as determined by navicular tuberosity height and the bony arch index. These findings demonstrate the inability of the clinician to predict the vertical height of the medial longitudinal arch on the basis of the amount of foot plantar surface area in contact with the ground during walking.

OBJECTIVES This study was to determine the acute response of the toe-spread-out exercise(TSE) on the medial longitudinal arch height(MLAH) and the static and dynamic balance.METHODS Twenty-four healthy young males and females were randomly assigned to the exercise group(n=12) or to the control group(n=12). The exercise group performed 40 repetitions of TSE while the control group had a rest on the chair. Before and after the exercise or rest, MLAH was measured while standing. One-leg standing test was conducted on the force plate with eyes closed and open. The total distance of the center of pressure (COP) was calculated to assess the static balance. Y-balance test was performed; and the anterior, and medial/lateral posterior reach distances were measured to assess the dynamic balance.RESULTS There was an interaction between group and time for the MLAH (p<.001), and the MLAH in the exercise group increased after the exercise (2.03±1.01 mm; t=-6.930, p<.001). There was an interaction between group and time for the anterior reach distance during the Y-balance test (p=.023), and the distance in the exercise group showed a strong tendency to increase after the exercise (t=-2.104, p=.059). No interaction was found for the total distance of the COP.CONCLUSIONS The 40 repetitions of TSE increased MLAH and showed a positive effect on dynamic balance in healthy young males and females. These results suggest that TSE can be useful as a new exercise method to improve the foot arch structure and function. Further research with the longer duration of TSE training for various populations is warranted.

The low-Dye strap is used routinely to temporarily control pronation of the foot and, thereby, to diagnose and treat pronatory sequelae. However, the exact biomechanical effects of this strapping technique on the foot are not well documented. The main purpose of this study was to establish the specific mechanical effects of the low-Dye strap on the pronatory foot. Within this context, the specific aim was to assess the effect of the low-Dye strap on three distinct pronation-sensitive mechanical attributes of the foot in the weightbearing state: 1) calcaneal eversion, 2) first metatarsophalangeal joint range of motion, and 3) medial longitudinal arch height. Weightbearing measurements of these three attributes were made before and after application of a low-Dye strap, and statistical comparisons were made. The results of this study indicate that the low-Dye strap is effective in reducing calcaneal eversion, increasing first metatarsophalangeal joint range of motion, and increasing medial longitudinal arch height in the weightbearing state. Knowledge of the exact mechanisms of action of the low-Dye strap will provide practitioners with greater confidence in the use of this modality. (J Am Podiatr Med Assoc 93(2): 118-123, 2003)
