Many distinct properties can affect the deformation of the tendon. Traditionally Young\u2019s modulus of tendon is evaluated from synchronized data of force and deformation. The purpose of this study was to examine whether the correlation between shear wave elastography and a traditional method would differ when the type of muscle contraction used in the traditional method was changed. Potential differences would help to understand which properties of the tendon shear wave elastography actually images.\n15 participants volunteered for this study. 13 of them had suffered from an acute tendon rupture 6 months before the measurements, and 2 of them 12 months before the measurements. The elastic properties of the tendon were evaluated by using shear wave elastography in a passive situation, as well as by using the traditional method where participants performed fast MVC, slow MVC, and 10% MVC muscle contractions.\nThe results of the shear wave elastography measurements of a healthy and passive leg correlated strongly with the Young\u2019s modulus measured by the traditional method during 10% MVC contraction (rho = 0,725 and p < 0,01). The Young\u2019s modulus measured during the slow MVC contraction of the healthy leg also correlated with the elastography measurements of the healthy leg (rho = 0,471 and p < 0,05). The correlation of a healthy leg between these two methods was statistically significantly stronger (Z = 2,071 and p < 0,05) than the corresponding correlation of an injured leg. Contraction velocity did not affect the correlation between these two methods.\nThe results of this study showed that the correlation between shear wave elastography and the traditional method was weaker in the case of the injured leg. Thus, the validity of shear wave elastography in studying a ruptured tendon should be further investigated. Based on the results of this study, the elastography measurements of the passive leg represent the deformation of the tendon with small-scale strains. Therefore, it would be important to evaluate if the information of properties with small-scale strains is valuable.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-11-16T05:45:16Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-11-16T05:45:16Z (GMT).
