CONTEXT Joint arthrometers have been developed to help determine the severity of ligament sprains. OBJECTIVE To establish intratester and intertester reliability of the talar inversion and anterior drawer tests using the LigMaster. DESIGN Intratester reliability was investigated using a repeated-measures design. Intertester reliability was investigated using 2 different clinicians testing s...

The present study was aimed to test a hypothesis that individuals with functional ankle instability (FAI) underestimate the joint angle at greater plantarflexion and inversion. Seventeen males with unilateral FAI and 17 controls (males without FAI) consented for participation in this IRB-approved, case-control study. Using a passive reproduction test, we assessed ankle joint position sense (JPS...

introduction anterior talofibular ligament (atfl) rupture is the most commonly injured anatomic structure in lateral ankle sprain. in some cases, atfl avulsion fracture from the lateral malleolus may occur instead of purely ligamentous injuries. the atfl avulsion fracture is detected as a small ossicle at the tip of lateral malleolus on direct radiographs, which is called os subfibulare in chro...

CONTEXT Lateral ankle sprains can manifest into chronic mechanical joint laxity when not treated effectively. Joint laxity is often measured through the use of manual stress tests, stress radiography, and instrumented ankle arthrometers. PURPOSE To systematically review the literature to establish the influence of chronic ankle instability (CAI) on sagittal and frontal plane mechanical joint ...

Underground displacement monitoring is a key means to monitor and evaluate geological disasters and geotechnical projects. There exist few practical instruments able to monitor subsurface horizontal and vertical displacements simultaneously due to monitoring invisibility and complexity. A novel underground displacement 3D measuring sensor had been proposed in our previous studies, and great eff...
