ABSTRACT

Introduction: The pelvis plays an important role during running, being key to the right distribution of loads on the two legs, maintaining the stability and alignment of both the limbs and the trunk. However, little is known about the relationship between poor pelvic stability and the distal segment of the lower limb (foot). The aim of this study was therefore to assess whether dynamic pelvic instability is related to any alteration of plantar pressures.
Patients and methods: In a sample of 47 healthy male runners, the single-leg squat test was video-recorded for evaluation by a panel of 5 experts. These formed the participants into three groups: bad pelvic control (BPC) (n = 8); medium pelvic control (RPC) (n = 14); and good pelvic control (GPC) (n = 25). Plantar pressures were measured running at 3.3 m/s, using the FootScan pressure platform. Peak pressure (N/cm²), time of peak pressure (ms), and load ratio (pressure/time, N/cm²·s) were determined in ten zones of the foot.
Results: The results showed the greatest peak pressures under the first (BPC = 14.7 N/cm², RPC = 10.7 N/cm², GPC = 7.9 N/cm²; p = 0.003) and second metatarsals (BPC = 16.8 N/cm², RPC = 4.8 N/cm², GPC = 10.3 N/cm²; p = 0.008). Also, there were significant differences in load ratio for the first metatarsal (BPC = 0.31 N/cm²·s, RPC = 0.23 N/cm²·s, and GPC = 0.18 N/cm²·s; p = 0.049).
Conclusions: Dynamic pelvic instability leads to greater pressures and load ratios in the medial area of the forefoot (first and second metatarsals), wich is usually related to pronation on the foot.



RESUMEN

Introducción: La pelvis juega un papel importante durante la carrera, siendo la clave en la correcta distribución de la carga entre las dos extremidades y manteniendo la estabilidad y el alineamiento entre las extremidades inferiores y el tronco. Sin embargo, poco se conoce sobre la relación de una pobre estabilidad pélvica en el segmento inferior distal (pie). Por ello, el objetivo de este estudio fue valorar si hay una relación entre la inestabilidad dinámica de la pelvis con una alteración de las presiones plantares.
Pacientes y métodos: En una muestra de 47 corredores sanos, se realizó el Single Leg Squat Test y fueron grabados en vídeo corriendo, siendo evaluados por un comité de cinco expertos. Se realizaron tres grupos: a) mal control pélvico (MPC) (n = 8); b) buen control pélvico (BCP) (n = 25); y c) control pélvico regular (RCP) (n = 14). Las presiones plantares se tomaron a 3.3 m/s con la plataforma de presiones FootScan. El pico de presión (N/cm2), tiempo de máxima presión (ms) y ratio de carga (N/cm2/s) fueron valorados en 10 regiones de interés.
Resultados: Los resultados obtenidos fueron máxima presión en primera (MCP = 14.7 N/cm2, RCP = 10.7 N/cm2, BCP = 7.9 N/cm2; p = 0.003) y segunda cabeza metatarsal (MCP = 16.8 N/cm2, RCP = 14.8 N/cm2 y BCP = 10.3 N/cm2, p = 0.008). También el ratio de carga (presión/tiempo) mostró diferencias significativas en la primera cabeza metatarsal (BCP = 0.31 N/cm2/s, RCP = 0.23 N/cm2/s y BCP= 0.18 N/cm2/s; p = 0.04).
Conclusiones: La inestabilidad dinámica de la pelvis produce mayor presión y ratio de carga en la región medial del antepié (primera y segunda cabeza metatarsal), lo que está normalmente relacionado con una mayor pronación del pie.
