A Mechano-Acoustic Indentor System for In Vivo Measurement of Nonlinear Elastic Properties of Soft Tissue

A Guideline of Selecting and Reporting Intraclass Correlation Coefficients for Reliability Research

“…Nowadays, ICC has been widely used in conservative care medicine to evaluate interrater, test-retest, and intrarater reliability (see Table 2 for their definitions). [10][11][12][13][14][15][16][17] These evaluations are fundamental to clinical assessment because, without them, we have no confidence in our measurements, nor can we draw any rational conclusions from our measurements.…”

Parameters Representing Muscle Tone, Elasticity and Stiffness of Biceps Brachii in Healthy Older Males: Symmetry and Within-Session Reliability Using the MyotonPRO

“…New measures of muscular properties are being developed, offering an in vivo, objective, clinical, non-invasive alternative to subjective assessments. These include tensiomyography or TMG, which uses electrical stimulation to elicit muscle oscillations to measure contraction time and muscle displacement [7]; various devices that measure tissue stiffness, such as muscle 'hardness' meters [8], myotonometry, which compresses (≥ 1 ≤ 2 seconds) the muscle to record tissue displacement [9,10], and a mechano-acoustic indentor system that records tissue displacement to measure non-linear elastic properties [11]; and the recently introduced Myoton technology, which elicits mechanically induced oscillations [12][13][14][15][16][17][18][19][20][21]. The different technologies have their relative advantages.…”

Measurement of the quadriceps muscle displacement and strain fields with ultrasound and Digital Image Correlation (DIC) techniques

“…Subsequently, Finite Element Model Updating (FEMU) was developed to determine the skin elastic behavior. In addition, ultrasound technique was used to better characterize the geometry of the skin and the environmental tissues with suction [10][11][12][13] or indentation tests [14][15][16][17]. This modeling provided a more accurate identification of the soft tissues.…”
