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.

Category: Midfoot/Forefoot Introduction/Purpose: Several conservative treatment methods, from intrinsic muscle exercises to orthoses, including insoles or specially designed shoes, have been introduced for pediatric flexible flat foot (PFFF). However, the structural effects of orthoses use remain unclear because the normal physiological maturation of the medial longitudinal arch cannot be ruled out. Methods: A comprehensive literature search using five databases, namely MEDLINE, the Cochrane Library, Scopus, the Web of Science, and EMBASE, was performed for pertinent articles published before March 30, 2018. Studies with quantitative data on the effects of the long-term use of orthoses for PFFF were included. The search strategy was adapted as appropriate for all other databases searched considering the differences in indexing terms and search syntax for each database. Results: All studies, including randomized controlled trials or prospective cohort studies, could not prove the estimated effects of orthoses on the medial longitudinal arch. However, they revealed that flexible flat feet in young children slowly improved with growth, regardless of the type of footwear used. However, three of four studies, which were case series, revealed that positive long-term effects could be achieved using orthoses. Conclusion: There is no strong evidence that the long-term use of orthoses improved the structural problem of PFFF.

Postoperative Problems

Background: Plantar fascia release for chronic plantar fasciitis has provided excellent pain relief and rapid return to activities with few reported complications. Cadaveric studies have led to the identification of some potential postoperative problems, most commonly weakness of the medial longitudinal arch and pain in the lateral midfoot. Methods: An electronic search was conducted of the MEDLINE, ScienceDirect, SportDiscus, EMBASE, CINAHL, Cochrane, and AMED databases. The keywords used to search these databases were plantar fasciotomy and medial longitudinal arch. Articles published between 1976 and 2008 were identified. Results: Collectively, results of cadaveric studies suggested that plantar fasciotomy leads to loss of integrity of the medial longitudinal arch and that total plantar fasciotomy is more detrimental to foot structure than is partial fasciotomy. In vivo studies, although limited in number, concluded that although clinical outcomes were satisfactory, medial longitudinal arch height decreased and the center of pressure of the weightbearing foot was excessively medially deviated postoperatively. Conclusions: Plantar fasciotomy, in particular total plantar fasciotomy, may lead to loss of stability of the medial longitudinal arch and abnormalities in gait, in particular an excessively pronated foot. Further in vivo studies on the long-term biomechanical effects of plantar fasciotomy are required. (J Am Podiatr Med Assoc 99(5): 422–430, 2009)

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)
