| Activation of stabilizing muscles of the hip (Gluteal Medium, Tensor of the Fascia Lata and Goutus maximus) It is intended to guarantee the activation of the gluteus maximus, fascia lata and gluteus maximus muscles by means of surface electromyography. For the tensor of the fascia lata and gluteus medius the test will be performed concomitantly to the force test for abductors in the load cell. While, for the maximum gluteus the test will be performed simultaneously to the test of hip extension force in the load cell. The operated and non-operated member will be evaluated in all tests (SENIAM, 2018). The value considered will be referring to the one of the greatest force performed by the participant during the test of maximum voluntary isometric contraction. In this study, an electromyograph of the Miotec brand (Miotec Equipamentos biomédicos LTDA, Porto Alegre, RS, Brazil), calibrated with a 1000-fold gain, 10Hz high-pass filter, 500Hz low-pass filter and 60 notch filter Hz. The sampling frequency shall be 2000 Hz. For the middle gluteus the electrodes will be positioned at 50% of the antero-superior iliac spine line to the greater trochanter, with 3cm distance between them, and the reference electrode will be positioned on the ulna styloid process (SENIAM, 2018) . In the electromyographic analysis of the tensor of the fascia lata the electrodes will be placed on 1/6 of the line of the antero-superior iliac spine to the lateral femoral condyle, with 3 cm of distance between them, being that the reference electrode will be positioned on the process styloid of ulna (SENIAM, 2018). For the assessment of maximal gluteal activation the electrodes will be positioned in 50% of the line between the sacrum and the greater trochanter. This position corresponds to the greater prominence of the buttocks just above the visible protrusion of the greater trochanter (SENIAM, 2018).
