About

With the help of ultrasound, the goal of the study is to asses the differences between MTR points and non painful points, in order to characterize the identification of MTR througought ultrasound. Being a complex process that needs to be standarized for each muscle, the study takes place in the vastus medialis.

Full description

Nowadays, myofascial trigger points (MTrP) represent one of the most common musculoskeletal alterations in clinic, being many times diffuse and complex to diagnose and localize. Ultrasound is a therapeutic tool used in physiotherapy for assessment and treatment. Some of its advantages include the quickness and harmlessness. Linking these two concepts, there is no vast evidence regarding the identification of myofascial trigger points through ultrasound. A computational mathematical analysis was performed throughout ultrasound images of the vastus medialis in order to characterize MTrPs, where images of 66 participants vastus medialis were taken. Two investigators made the finger point palpation locating a MTrP and a non-painful point. A third investigator screened the photographs with the ultrasound and a preset for the zone. 3 images were taken from the MTrP, 3 from the non-painful point, and other 3 of a different MTrP, in case the investigators disagreement of the MTrP location. A fourth investigator carried out the histogram analysis using Fiji software. Lastly, stastistical analysis of the study variables was performed.
