“…By definition, the volunteers with various degrees of MLA were classified according to the protocol designed by Cavanagh and Rodgers [ 22 ] related to index arch, in agreement with previous studies that have analyzed these factors to show standard assessment of this condition and contributed to medical diagnostic and medical treatment of the foot problems [ 31 , 32 ].…”

Background: Variations in the foot structure related with the high or low arch are identified common lower limb conditions, and it is supposed to be the effect on the quality of life (QoL) associated to foot health in adults. Here we aimed to determine the relationships between relatively high and low feet arches and QoL. Methods: A cross-sectional study was carried out. Among 138 adults enrolled in the study, 66 had a high arch, 21 had a low arch, and 51 were within the normal range. Changes related to the foot structure were analyzed using Area Calc version 2.6 software, and data obtained using the Foot-Health-Status-Questionnaire (FHSQ), whose domains were compared between foot arch groups by means of the one-way analysis of variance (ANOVA). Results: The results of the FHSQ comparison between the three groups within the sample population did not show any statistically significant difference (p > 0.05) for any domains of specific foot (pain, function, general health and footwear) and general (general health, physical activity, social function and vigor) health-related QoL. Conclusions: Specific foot and general health-related QoL did not seem to be influenced by the foot arch height between high, normal and low feet arches heights. Nevertheless, further studies with higher sample sizes and matched-paired groups should be carried out.

“…Dentro de las limitaciones de este estudio, se encuentra el hecho que el baropodoscopio empleado no diferenciaba entre las presiones plantares registradas en las distintas zonas del pie, lo cual no permite evaluar estos resultados en comparación con otros autores que encuentran aumento de los valores de presión plantar en zonas específicas, tales como la región del antepié (Szulc et al, 2017). Asimismo, se observa que una buena cantidad de estudios han utilizado plantillas instrumentadas, equipamiento que puede diferir en los resultados que se obtienen en una plataforma (Chevalier, Hodgins, & Chockalingam, 2010) La variable AI, que a través del análisis de las áreas de apoyo plantar permite determinar la constitución del APLM y a su vez clasificar los pies en planos, normales y cavos, sólo mostró diferencias significativas entre el pre y post test dentro del pie no dominante en GD, con tendencia hacia el aplanamiento de la bóveda plantar, tal como lo planteado por Tsung y colaboradores (Tsung et al, 2003) y Jiménez y colaboradores (Jimenez-Ormeño et al, 2011). Un estudio similar realizado en carrera, es el hecho por Maslon y colaboradores (Maslon, Golec, Szczygiel, Czechowska, & Golec, 2016), quienes encontraron que los corredores aplanan más la bóveda plantar, como un mecanismo de amortiguación activa de fuerzas.…”

El objetivo de esta investigación fue analizar modificaciones agudas que se producen en la morfología del pie y distribución de presiones plantares luego de la aplicación de un protocolo de carrera a pie descalzo. 42 sujetos de ambos sexos participaron de este estudio, quienes fueron divididos en Grupo Calzado (GC) (n=20) y Grupo Descalzo (GD) (n=22). Se evaluó antropometría del pie, índice del arco (AI) y presiones plantares antes y después de la intervención, que consistió en correr a 3,05 m·s-1 durante 20 min. El pie no dominante del GD disminuyó la altura de su arco plantar (AI pre=0,20, AI post=0,22; p=0,01; ES=0,4), asimismo, la carrera descalza produjo en el pie no dominante menores aumentos en los valores de presión plantar y menores disminuciones en la superficie de apoyo plantar que el correr con calzado.

“…Before making the measurements, every subject rested for 10 min in supine position so as not to alter the foot's postural dynamics (Jimenez-Ormeño et al, 2011). Then the body weight and height were measured and the plantar support was evaluated dynamically (Baseline).…”

Background Although the studies of barefoot running have intensified, it is still missing longitudinal work analyzing the effects of barefoot running on the phases of plantar support. The objective of this research was to analyze the modifications undergone by the Total Foot Contact (TFC) phase and its Flat Foot Phase (FFP) in subjects beginning the practice of barefoot running, in its acute and chronic effects. Methods A total of 28 subjects were divided into the Barefoot Group (BFGr) (n = 16) and the Shod Group (SHGr) (n = 12), evaluated before (Baseline) and after running for 20 min at 3.05 m·s−1 (Post 20 min Running), and at the end of a running training protocol with an 8-week long progressive volume (Post-8-week Training). The dynamic plantar support was measured with a baropodoscope. The duration of TFC (ms), the moment at which the FFP occurred, the maximum surface of TFC (MSTFC) (cm2), the FFP surface (SFFP) (cm2), the peak pressure of TFC (PP°TFC) (kg·cm−2), and the peak pressure of FFP (PP°FFP) (kg·cm−2) were recorded. The 3 × 2 ANOVA analysis was made to determine the effects and interactions that the condition produced (Shod/Barefoot), and the time factor (Baseline/Post 20 min Running/Post-8-week Training). Results The condition factor caused more significant effects than the time factor in all the variables. Duration of TFC in BFGr showed significant differences between the Baseline and Post-8-week Training (p = 0.000) and between Post-20-min Running and Post-8-week Training (p = 0.000), with an increasing trend. In the moment at which the FFP occurred a significant increase (p = 0.029) increase was found in Post-20 min Running (48.5%) compared to the Baseline (42.9%). In MSTFC, BFGr showed in Post-8-week Training values significantly higher than the Baseline (p = 0.000) and than Post-20-min Running (p = 0.000). SHGr presented a significant difference between the Baseline and Post-8-week Training (p = 0.040). SFFP in BFGr modified its values with an increasing trend (p = 0.000). PP°TFC in BFGr showed a significant decrease (p = 0.003) in Post-8-week Training (1.9 kg·cm−2) compared to the Baseline (2.4 kg·cm−2). In PP°FFP significant decreases were recorded in BFGr and between Post-8-week Training and Baseline (p = 0.000), and Post-8-week Training and Post 20 min Running (p = 0.035). Conclusions The adaptation took place after the 8-week training. The adaptations to running barefoot were characterized by causing an increase of the foot’s plantar support in TFC and in FFP, as well as a decrease of the plantar pressure peak in both phases. Also, there is an increased duration of the TFC and FFP, which may be related to an acquired strategy to attenuate the impacts of the ground’s reaction forces.
