|---|---|
| For the Mulligan group evaluations, the following instruments were used: sociodemographic questionnaire, algometer, baropodometer, traction dynamometer and surface electromyography (EMGs). Initially, sociodemographic information was collected (age, address, telephone, profession) and mass and height . For static balance analysis, the FootWork Pro baropodometer (IST-Informatique, France) was used to observe the body mass distribution, stabilometry and displacement of the body pressure center (COP) in orthostatism. The volunteers were positioned in orthostatism on the platform with equidistant feet, guaranteed by means of a 10 cm template between the medial malleoli of the ankle. The static balance was assessed with blindfolded eyes and ears covered with the aid of a muffler. Three collections of 60 seconds were performed with 60 second rest between each collection, in order to avoid possible fatigue. The data were acquired at a frequency of acquisition of 100 Hz and analyzed in the software FootWork Pro v. 3.2.2.0 - (IST Informatique, France). The analysis of body mass distribution was in the anterior, posterior, left and right regions. For electromyographic evaluation of the rectus femoris, vastus medialis, vastus lateralis and soleus muscles, the Trigno 8 Channel Wireless device (EMGworks, Delsys Inc., Boston, USA) equipped with EMGWorks 4.0 Acquisition software was used. The mode of acquisition of the electromyographic signals was calibrated for a sampling frequency of 1000Hz, calibrated with 1000 times gain, 20Hz high pass filter, 500Hz low pass filter and 60Hz filter to prevent grid interference. To minimize possible interference in the acquisition of the electromyographic signal, the tricotomy and cleaning of the skin with 70% alcohol were performed at the fixation site of the electrodes. The electrodes were fixed on the skin of the volunteer with double face tape and positioned on the muscles to be analyzed as recommended by the European Society of Surface Ele | — |
