“…Dorsiflexion ranges from 3 to 8 mm in healthy adults and one article authored in 2006 by Glasoe and Coughlin (who in a long series of independent and unaffiliated research studies measured with two different types of mechanical devices) made a consensus statement that FRM averages 5 mm in healthy adults, and that values exceeding 8 mm indicate hypermobility [ 39 ]. The measure of 6.47 mm in dorsiflexion reported in the present study equates FRM dorsiflexion values that were reported in the literature [ 8 , 36 , 37 ]. Most of this data was recorded by researchers who used singularly designed and well tested mechanical devices (for reliability and validity) for this purpose.…”

The first metatarsal and medial cuneiform form an important functional unit in the foot, called “first ray”. The first ray normal range of motion (ROM) is difficult to quantify due to the number of joints that are involved. Several methods have previously been proposed. Controversy exists related to normal movement of the first ray frontal plane accompanying that in the sagittal plane. The objective of this study was to investigate the ROM of the first ray in the sagittal and frontal planes in normal feet. Anterior-posterior radiographs were done of the feet of 40 healthy participants with the first ray in a neutral position, maximally dorsiflexed and maximally plantarflexed. They were digitalized and the distance between the tibial malleolus and the intersesamoid crest in the three positions mentioned was measured. The rotation of the first ray in these three positions was measured. A polynomic function that fits a curve describing the movement observed in the first ray was obtained using the least squares method. ROM of the first ray in the sagittal plane was 6.47 (SD 2.59) mm of dorsiflexion and 6.12 (SD 2.55) mm of plantarflexion. ROM in the frontal plane was 2.69 (SD 4.03) degrees of inversion during the dorsiflexion and 2.97 (SD 2.72) degrees during the plantarflexion. A second-degree equation was obtained, which represents the movement of the first ray. Passive dorsiflexion and plantarflexion of the first ray were accompanied by movements in the frontal plane: 0.45 degrees of movement were produced in the frontal plane for each millimeter of displacement in the sagittal plane. These findings might be useful for the future design of instruments for clinically quantifying first ray mobility.

“…Klaue et al reported that the dorsiflexion of the first ray was 5.3 mm [ 10 ]. Various authors have then used this device, obtaining diverse results: 4.4 mm [ 33 ], 4.9 mm [ 34 ], 5.6 mm [ 35 ], 6.85 mm [ 36 ], and 7.2 mm [ 37 ]. Glasoe et al observed that the first ray dorsiflexion was 4.2 mm [ 9 ].…”

“…This device produces a force displacement measurement, and records movement from a probe placed on the head of the first metatarsal. In spite of these instruments having been used in various studies, [11][12][13][14][15][16] they have some inconveniences such as, for example, being too complex, being large, not quantifying plantarflexion (which would be useful to compare with dorsiflexion), or not reflecting the combined movements of dorsiflexion-inversion and plantarflexion-eversion [4,17]. These are possible reasons why they are not used in daily clinical practice [8].…”

Several methods have been described to quantify the first ray mobility. They all have certain disadvantages (great size, sophistication, or lack of validation). The objective of this work was to study the validity and reliability of a new instrument for the measurement of first ray mobility. Anterior-posterior radiographs were obtained from 25 normal feet and 24 hallux valgus feet, with the first ray in a neutral position, maximally dorsiflexed and maximally plantarflexed. The first ray mobility was radiographicaly measured in both groups, and was also manually examined with the new device. A cluster analysis determined whether normal and hallux valgus feet were correctly classified, and a graphic analysis of Bland-Altman was performed to compare the radiographic and manual measurement techniques. Based on the radiographs, the first ray mobility only showed significant differences in dorsiflexion between both groups (P = 0.015). First ray dorsiflexion, plantarflexion and total range of motion measured with the new device were different between both groups (P = 0.040, P = 0.011 and P = 0.006, respectively). The silhouette measure of the cohesion and separation coefficients from the cluster analysis was greater than 0.50 for the dorsiflexion, plantarflexion and total range of motion obtained from the radiographs and from the new device. The Bland-Altman graph suggested that 96% of the data presented agreement between both measurement methods. These results suggested that the new instrument was valid and reliable.

“…En este sentido, los momentos de pronación excesivos de la articulación subastragalina durante la fase propulsiva de la marcha van a aumentar la movilidad articular del pie, perdiendo así la capacidad de comportarse como una palanca rígida que permita de una forma correcta la propulsión y progresión del paso (25)(26)(27)(28)(29). De esta forma, el músculo peroneo lateral largo se vuelve incapaz de anclar la cabeza del primer metatarsiano al suelo al disminuir su vector de fuerza de palanca y de función plantarflexora (25,29,30).…”

“…De esta forma, el músculo peroneo lateral largo se vuelve incapaz de anclar la cabeza del primer metatarsiano al suelo al disminuir su vector de fuerza de palanca y de función plantarflexora (25,29,30). A este modelo patomecánico, debemos de sumarle que las FRS en la última fase del proceso de la marcha producen una dorsiflexión e inversión del primer metatarsiano, destacado entre las demás estructuras del primer radio (11,25,26).…”

Objetivos: El síndrome de estrés tibial medial (SETM) es una lesión de sobreuso por estrés mecánico, que se localiza por lo general en el borde postero-medial de la tibia. El objetivo de este estudio es cuantificar la diferencia baropodométrica existente en la primera cabeza metatarsal entre dos grupos. Métodos: Se analizaron las huellas de 30 participantes, de los cuales 15 padecían SETM y 15 controles. Se trata de un estudio observacional en el que se obtuvieron las huellas baropodométricas de los participantes, caminando sobre una plataforma de presiones. Se cuantificó la presión plantar media y la integral presión/tiempo que estaba recibiendo cada paciente en la primera cabeza metatarsal. Realizamos la prueba t-student para muestras independientes con el objetivo de definir las diferencias.Resultados: Los resultados de la variable presión plantar media muestran diferencias estadísticamente significativas entre los 2 grupos (p=0,001 para pie izquierdo y p=0,001 para pie derecho). Por el contrario no se observaron diferencias estadísticamente significativas para la variable integral presión/tiempo en ambos grupos (p=0,327 para pie izquierdo y p=0,300 para pie derecho).Conclusiones: Según nuestro estudio, los resultados obtenidos concluyen que el SETM se ocasiona con mayor frecuencia en personas con una disminución significativa de la presión plantar en la cabeza del primer metatarsiano medida en plataforma baropodométrica. Consideramos que son necesarios más estudios que evidencien esta relación biomecánica mediante plantillas instrumentadas.
