The thesis deals with the evaluation of the influence of foam rolling on selected parameters of somatosensory perception (pressure-algic threshold, vibrotactile sensation). The theoretical part discusses fascial tissue, summarizes the current knowledge of foam rolling and focuses on the mechanisms of pain and vibrotactile sensation. The research part consists of a randomized blind study on a group of 15 healthy probands (11 women, 4 men), which evaluates the effect of foam rolling. The effect is objectivized by pressure algometry and vibrametry on the m. rectus femoris and m. biceps femoris of both lower limbs (measured before and after therapy). The value of the pressure pain threshold (PPT) increased after foam rolling. Vibrotactile threshold (VT) was lower after foam rolling than before its use, which means that vibrotactile sensitivity was increased. The results show that these changes do not occur only in the interventioned m. rectus femoris, but some changes in parameters can be found in other muscles as well.

Diplomová práce Hodnocení krátkodobého efektu aplikace rázové vlny na MTrP Abstract This thesis concerns the application of radial extracorporeal shockwave therapy into muscular trigger points. It's location is derived from the descending part of trapezius muscle on the side of the dominant upper extremity. The performance analysis is based on using partially double-blind placebo-controlled, randomized clinical trial. The effects of the therapy were investigated in 28 subjects divided into experimental and control groups and objectively manifested by measuring the pressure pain threshold. Furthermore, the measuring of the active range of motion of the cervical spine, and the measuring of the maximal voluntary wrist and third finger flexion (measured before and after the therapy). After the therapy, the pressure pain threshold value of the trigger point located in trapezius muscle increased on average from 199 to 295 kPa (p = 0,025). The cervical spine lateral flexion increased on average by 3 degrees towards to the side of non-dominant upper extremity (p = 0,045). This study also investigates the pressure pain threshold value changes of 7 reference points placed remotely from the area of the application. After the shockwave therapy, the pressure pain threshold values of these reference points increased on...
