Modeling and Analysis of the Viscoelastic Response of the Ankle Ligament Complex in Inversion Ankle Sprain

Abstract: Since inversion ankle sprain (IAS) damages ankle ligaments and induces changes in their viscoelastic properties, evaluating these properties may provide an approach to assess injury. The study purposes were to investigate how the viscoelastic properties of the ankle ligament complex can be used to quantitatively assess IAS, and to investigate the usefulness of the stretched exponential function to analyze the relaxation behavior of the ankle ligament complex. Fifteen participants with unilateral IAS and 15 con… Show more

“…However, 13 of the 33 studies did not use a questionnaire nor any other form of quantifying the amount of functional impairment. Eleven studies used manual testing, two used additional stress radiographs and one used stress radiographs only, another study used stress sonography and one used plain radiographs as a reference standard.…”

“…However, only four of the ten studies reported a statistically significant increase . Many authors compared CAI to the contralateral healthy ankle in unilateral CAI, while four groups compared their values to ankle sprain copers . Four studies reported significant differences in inversion ROM between a CAI and a healthy control group (supplementary Table S1) .…”

“…The ground reaction force is more or less the same magnitude in all motions, however, if the moment arm is increased as a result of a larger angle of deviation, the resultant inversion torque can increase dramatically. Finally, as the whole motion usually happens within a very short time, ligaments are sprained as they possess viscoelastic property 31 , which means they can sustain a force if it is applied slowly on them, but they cannot if it is applied suddenly.…”

“…Measurement of the mechanical properties of musculoskeletal soft tissues is a promising method for objectively evaluating the degree of injury and health status of tissues. It has been reported that injuries induce significant changes in the mechanical properties of tissues such as tendons and ligaments [14][15][16], and these changes may directly impact their functional performances [16][17][18]. Shear wave ultrasound elastography (SWE) is an imaging technique designed to noninvasively evaluate the mechanical properties of tissues [19][20][21][22][23].…”
