Assessment of the mechanical properties of the muscle-tendon unit by supersonic shear wave imaging elastography: a review
نویسندگان
چکیده
This review aimed to describe the state of the art in muscle-tendon unit (MTU) assessment by supersonic shear wave imaging (SSI) elastography in states of muscle contraction and stretching, during aging, and in response to injury and therapeutic interventions. A consensus exists that MTU elasticity increases during passive stretching or contraction, and decreases after static stretching, electrostimulation, massage, and dry needling. There is currently no agreement regarding changes in the MTU due to aging and injury. Currently, the application of SSI for the purpose of diagnosis, rehabilitation, and physical training remains limited by a number of issues, including the lack of normative value ranges, the lack of consensus regarding the appropriate terminology, and an inadequate understanding of the main technical limitations of this novel technology.

Posture and Activation Dependent Variations in Shear Wave Speed in the Gastrocnemius Muscle and Aponeurosis
Musculotendon tissue interactions are strongly dependent on the morphological and mechanical characteristics of the aponeurosis [1]. Despite its mechanical significance, the material properties of the aponeurosis are not well understood. In fact, the literature reports conflicting results concerning the relative stiffness of tendon and aponeurosis tissue [2, 3], which may arise from the challen...

Ultrasound is an essential modality within musculoskeletal imaging, with the recent addition of elastography. The elastic properties of tissues are different from the acoustic impedance used to create B mode imaging and the flow properties used within Doppler imaging, hence elastography provides a different form of tissue assessment. The current role of ultrasound elastography in the musculoske...

BACKGROUND Semitendinosus/gracilis (STG) tendon autograft has been used effectively for restoring knee stability after anterior cruciate ligament (ACL) rupture. Though ACL reconstruction with STG autograft is an effective surgical technique for return to sports, short-term hamstring strength asymmetries exist after surgery. Although imaging evidence has demonstrated regrowth and reorganization ...
متن کاملDetermination of Achilles Tendon Slack Length Using Supersonic Shear Imaging
Passive mechanical properties of the musculo-articular complex are classically studied using passive torque-angle curves. However, the mechanical properties of each structure of this musculo-articular complex (e.g., muscle, tendon) cannot be dissociated from this relationship. We recently showed that supersonic shear imaging is able to accurately quantify muscle shear elastic modulus of one mus...
متن کاملNew Imaging Methods for Non-invasive Assessment of Mechanical, Structural, and Biochemical Properties of Human Achilles Tendon: A Mini Review
The mechanical properties of tendon play a fundamental role to passively transmit forces from muscle to bone, withstand sudden stretches, and act as a mechanical buffer allowing the muscle to work more efficiently. The use of non-invasive imaging methods for the assessment of human tendon's mechanical, structural, and biochemical properties in vivo is relatively young in sports medicine, clinic...
