ABSTRACT

Objectives: Metatarsal overload is treated through selective off-loads, temporary or definitive. Thus, is proposed the implementation of a selective off-loading element (U-shaped) fitted in socks under the central forefoot. The aim of this study was to assess plantar pressures of the prototype in regard to a control sock made of the same fibers and pattern.
Patients and methods: Plantar pressures of 21 individuals (9 men and 12 women) were analyzed using the platform Footscan ® (RSscan int). First, individuals wore their own socks, in the second analysis (randomly) they wore control socks and the socks having the off-loading pad implemented under the forefoot plantar area (experimental socks). Individuals answered a comfort survey, in which Likert scale (from 1 to 5) was used.
Results: A statistically significant reduction (P = 0.037) in the plantar pressure values was observed in the third metatarsal head: from 14.9 N/cm2 in barefooted patients and 14.7 N/cm2 in patients wearing the control sock to 12.3 N/cm2 in patients wearing the experimental sock. Regarding comfort, individuals gave a score of 3.13 ± 0.5 to the control sock, and 4.74 ± 0.5 to the experimental sock, showing a statistically significant difference among them (p < 0.001).
Conclusions: Experimental socks turned out to be more comfortable for the sample, and to reduce plantar pressure from the third metatarsal head. This could lead on to less discomfort for subjects having predisposition to pain in the area, and to avoid possible dermis injuries related to overpressure.



RESUMEN

Objetivos: Las sobrecargas metatarsales se tratan con descargas selectivas, provisionales o definitivas. Así, se propone implantar un elemento de descarga selectiva (forma de U) en el antepié central integrado en unos calcetines. El objetivo de este trabajo fue evaluar el patrón baropodométrico del modelo experimental respecto a un calcetín control fabricado en las mismas fibras y diseño.
Pacientes y métodos: En una muestra de 21 sujetos (9 hombres y 12 mujeres) se analizaron las presiones plantares con la plataforma Footscan® con sus propios calcetines, seguido (de forma aleatoria) con los calcetines control y posteriormente con otros iguales pero con el elemento de descarga en la zona plantar del antepié (calcetines experimentales). Los sujetos contestaron una encuesta de comodidad, mediante una pregunta tipo Likert de 1 a 5.
Resultados: En la tercera cabeza metatarsal se vio una reducción estadísticamente significativa (p = 0.037) de los valores depresión plantar, de los 14.9 N/cm2 de los pacientes descalzos y 14.7 N/cm2 del calcetín control a los 12.3 N/cm2 en el calcetín experimental. En relación con el confort, los sujetos puntuaron con un 3.13 ± 0.5 al calcetín control y 4.74 ± 0.5 al calcetín experimental, con una diferencia estadísticamente significativa entre ambos (p < 0.001).
Conclusiones: Los calcetines experimentales resultaron más cómodos para los sujetos de la muestra, reduciendo la presión plantar en la tercera cabeza metatarsal. Esto podría conllevar una menor molestia para individuos con predisposición al dolor en dicha zona, así como evitar la aparición de posibles lesiones dérmicas asociadas a la hiperpresión.
