Intramuscular Temperature on the Echo-textural Characteristics
Recruiting now · Not applicable
Conditions studied: Healthy Subjects
In brief
Echointensity and echotexture have been used as a physiological marker for changes in skeletal muscle quality and structure caused by physical training, low activity, ageing and some neuromuscular disorders. However, there are some influencing factors on muscle echo-intensity and echotexture, such as temperature, which may not be taken into account when performing an ultrasound assessment and may alter the results. This study aims to investigate the effects of muscle temperature on echointensity and other 2nd order echotextures variables such as homogeneity, contrast, correlation and entropy of muscle tissue, in order to gain a better understanding of this correlation and minimise its influence, which would allow greater precision in the use of muscle ultrasound as a diagnostic tool. The methodology of this study includes firstly the acquisition of ultrasound images of the vastus lateralis muscle. This acquisition will be performed during the continuous recording of muscle temperature, carried out during a passive cooling process after 20 min of heating using microwave equipment. In addition, to standardise the results, a correction factor will be calculated to compensate for the influence of subcutaneous adipose tissue thickness on echogenicity and echotexture.
