Ankle dorsiflexor physical therapy device

Abstract

The present inventive concept relates to a physical therapy device designed to isolate and strengthen ankle dorsiflexors and related muscle groups without compressing major neurovascular bundles that cross the ankle joints. The present inventive concept combines fulcrums along the medial and lateral aspects of the ankle with resistance along the posterior aspect of the ankle to achieve mobility and resistance against motion during use. Benefits of the present inventive concept include improved ankle stability and dexterity, mitigation of ankle injuries, and prevention of neurovascular compression around the ankle during use.

1 . A physical therapy device that combines fulcrum along the sides of the ankle with resistance across the posterior aspect of the ankle to achieve ankle dorsiflexion strengthening within anatomical range of motion during use. 
     
     
         2 . A physical therapy device that when applied during designated active range of motion allows space for vascular and nerve bundles that cross the anterior and medial aspects of the ankle joint thereby preventing compression to them.
 1. The design comprises anchors  116  and  118  along the medial and lateral malleoli of the ankle that are part of the ankle ring module  110 , and grooves  120 ,  116 , and  118  (deep surface indentation) on the device along sites overlying major neurovascular bundles at the ankle.
