Side lying hip abduction11/11/2022 ![]() A disposable single surface electrode with the Ag/Agcl material was used. The EMG activity of the GM, QL, EO and IO of the leg for which abduction was performed was collected using a TeleMyo DTS EMG (Noraxon Inc., Scottsdale, AZ, USA). Keywords: Trunk stabilization, Pelvic lateral rotation, Electromyography Based on these results, we suggest that abdominal bracing increases the muscle activity of QL, EO, and IO, and decreases the angle of PLR compare to abdominal hollowing during SHA. The muscle activity of the IO was significantly greater for SHA-AH and SHA-AB compared to SHA-WC. And the muscle activity of the EO for SHA-AH was significantly greater than that for SHA-WC. The muscle activity of the EO was significantly greater for SHA-AB compared to SHA-AH and SHA-WC. The muscle activity of the QL was significantly greater for SHA-AB compared to SHA-AH and SHA-WC. The angle of PLR in SHA-AB was significantly lower compared to SHA-AH and SHA-WC, and angle of PLR in SHA-AH was significantly lower than that in SHA-WC. The subjects performed three conditions in side-lying in random order: SHA with abdominal hollowing (SHA-AH), SHA with abdominal bracing (SHA-AB), and SHA without any condition (SHA-WC). A total of 22 healthy male adults participated in the study. The purpose of the present study is to investigate the effects of abdominal hollowing and abdominal bracing during SHA on pelvic lateral rotation (PLR) and the electromyography activity of the gluteus medius, quadratus lumborum (QL), external oblique abdominis (EO) and internal oblique abdominis (IO). Continue in one direction for 30 seconds.It is important that compensatory lateral movement of the pelvis does not occur during side-lying hip abduction (SHA).Follow by stepping the left foot to the right side too, so that your knees are once again under your shoulders.Step out to the right side with your right foot.Keep your knees in line with your toes, stick your butt out slightly while tucking your hips under to protect the lower back. Place hands in a prayer shape in front of your chest, and keep your legs shoulder-distance apart.While standing, put both feet through the resistance band.Perform exercise on both sides of the body.Without lifting your feet, open your top thigh and lift the left knee towards the ceiling.Bend both of your knees and stack feet on top of each other.Place a resistance band around both of your thighs.This is the same setup as the previous exercise. Keep right arm under your head, and left arm on your hip. Start with your right side on the ground, and keep hips in line with the rest of your body. Remember to perform the exercise on both sides of your body.This is as far as the hip abductors can be engaged before it starts to involve other hip muscles instead. Lift your left leg, keeping it in line with your hip.Bend your bottom (right) knee, and straighten out the left. ![]()
