big toe under load, not explained by structural osteoarthritis. This blockage disrupts the windlass mechanism and delays the transition from pronation to supination at the propulsive moment. This results in a lateralized roll, an external taligrade attack and chain compensations.<br><br>This dysfunction is not a local detail: it affects running economy and walking stability. Identifying HLF sheds light on the origin of pain sometimes attributed to the knee alone, when the initial problem is located in the forefoot.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-fde560e3 e-con-full conteneur_vid_1 e-flex e-con e-child\" data-id=\"fde560e3\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1059df98 titre_vid_2 elementor-widget elementor-widget-heading\" data-id=\"1059df98\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Simple clinical diagnosis: the stretch test and walking<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ff074184 elementor-widget elementor-widget-text-editor\" data-id=\"ff074184\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The stretch test consists of stabilizing the base of the first metatarsal, with the ankle in dorsiflexion, then pushing the hallux into extension.
