“…Amount of individualization of the shape of the orthoses in this study was consistent for all participants and no corrective posting was applied. Controlling kinetic and kinematic responses (dose-response) across a group of participants hasn't been investigated previously (Griffiths and Spooner, 2018;Hoogkamer et al, 2018). Our results, with large inter-individual variability, highlight the fact that a "one-fits-all approach" must not be taken when interpreting mechanical and metabolic results.…”

Custom made foot orthoses (CFO) with specific material properties have the potential to alter ground reaction forces but their effect on running mechanics and comfort remains to be investigated. We determined if CFO manufactured from ethyl-vinyl acetate (EVA) and expanded thermoplastic polyurethane (TPU) materials, both compared to standardized footwear (CON), improve running economy (RE), running mechanics, and comfort at two running speeds. Eighteen well-trained, male athletes ran on an instrumented treadmill for 6 min at high (HS) and low (LS) speeds corresponding to and 15% lower than their first ventilatory threshold (13.8 ± 1.1 and 11.7 ± 0.9 km.h −1 , respectively) in three footwear conditions (CON, EVA, and TPU). RE, running mechanics and comfort were determined. Albeit not reaching statistical significance (P = 0.11, η 2 = 0.12), RE on average improved in EVA (+2.1 ± 4.8 and +2.9 ± 4.9%) and TPU (+0.9 ± 5.9 and +0.9 ± 5.3%) compared to CON at LS and HS, respectively. Braking force was decreased by 3.4 ± 9.1% at LS and by 2.7 ± 9.8% at HS for EVA compared to CON (P = 0.03, η 2 = 0.20). TPU increased propulsive loading rate by 20.2 ± 24 and 16.4 ± 23.1% for LS and HS, respectively compared to CON (P = 0.01, η 2 = 0.25). Both arch height (P = 0.06, η 2 = 0.19) and medio-lateral control (P = 0.06, η 2 = 0.16) showed a trend toward improved comfort for EVA and TPU vs. CON. Compared to shoes only, mainly EVA tended to improve RE and comfort at submaximal running speeds. Specific CFO-related running mechanical adjustments included a reduced braking impulse occurring in the first 25% of contact time with EVA, whereas wearing TPU increased propulsive loading rate.

“…The published studies on orthotics in runners are generally difficult to generalize because most lack a control group and have a small sample size. 37 In addition, orthotic fitting is highly practitioner dependent. 19 Runners themselves believe that orthotics and shoe design matter.…”

Distance runners represent a unique patient population. The cyclic activity associated with distance running leads to a high incidence of injury. Gait patterns, the extrinsic and intrinsic muscles of the foot and ankle, foot strike pattern, shoe wear considerations, alignment, and orthotics are also all important considerations that must be considered by the treating provider. The purpose of this work is to review relevant functional anatomy, recent studies on gait patterns in running, orthotics, and theory on how the body moves through space during running in order to better equip the clinician to treat long distance runners.

“…Mes No diferencias estadísticamente significativas en ninguna de las comparaciones todas ellas. Griffiths y Spooner proponen que los efectos de las ortesis plantares son principalmente atribuibles a los cambios cinéticos que estas producen en los diferentes tejidos del pie y miembro inferior 28 . En este sentido, el presente estudio ha utilizado un tipo de plantilla ortopédica a medida centrada en esta idea con reducción de la carga en el proceso medial de la tuberosidad posterior del calcáneo, mostrando una mejoría importante del dolor en un plazo de 1-3 meses, cuando las plantillas se encuentran bien adaptadas.…”

ResumenObjetivos: No existen todavía evidencias sólidas para el uso de ortesis plantares en el tratamiento de pacientes con dolor de talón asociado a fasciopatía plantar. El presente trabajo valora el efecto de un tipo de ortesis plantar a medida con elementos específicos de descarga en el dolor y el grosor de la fascia plantar.Pacientes y métodos: Se realizó estudio prospectivo de serie de casos en pacientes con fasciopatía plantar unilateral con tratamiento conservador por medio de ortesis plantares a medida rígidas en polipropileno con molde en semicarga y con descarga específica del proceso medial de la tuberosidad posterior del calcáneo y aumento de la cazoleta posterior. Se midió el dolor mediante escala analógica visual y grosor de la fascia plantar en 4 localizaciones antes del tratamiento y durante el tratamiento al mes, tres y seis meses.Resultados: De los 42 pacientes inicialmente reclutados hubo pérdidas hasta llegar a 18 pacientes a los 6 meses. Se observó una disminución del dolor al mes, a los 3 meses y a los 6 meses, que fue estadísticamente significativa en todas las comparaciones. Se observaron diferencias estadísticamente significativas en el grosor de la fascia plantar entre la valoración inicial y al sexto mes con disminución del grosor.Conclusiones: A pesar de no tratarse de un ensayo clínico aleatorizado, los resultados mostraron una reducción estadísticamente significativa del dolor al primer, tercer y sexto mes, sugiriendo que las plantillas con este tipo de prescripción específica podrían ser efectivas en la mejoría sintomática de estos pacientes.
