Amnesia, memory loss. Inability to remember something in the recent or distant past. The term most commonly associated with neurological issues, such as memory loss after traumatic brain injury. In this sense, which I want to describe, it refers to muscle structures that are not used, they „forget“ their function and thus come to the consequences that bind problems in other segments. Gluteus, belong to the group of posterior pelvic muscles. It consists of three muscles, m. gluteus maximus as the largest, m. gluteus medius, which is extremely important for maintaining an upright body during walking, and m. gluteus minimus, which is responsible for the abduction of the thigh. When inhibitions, inhibitions in the transmission of nerve impulses or insufficient activation of muscle groups or improper performance of movements occur, consequences also occur. In the 21st century, with the modernization of lifestyles and advances in technology from which we benefit greatly as humanity, some undesirable effects have receded. With a sedentary lifestyle, we have compromised the function of our glutes and this has resulted in problems in the painful back, the anterior tilt of the pelvis, and many other compensatory mechanisms. But the connection between lower back pain and sedentary life is not the only parallel. On the other hand, we encounter the same problem with professional athletes such as athletes, especially marathoners. Due to the biomechanics of the movement they perform, their hip flexors (m. psoas major, m. iliacus, m. rectus femoris, m. pectineus and m. sartorius) are shortened and amnesia occurs in the gluteus region. The purpose of a physiotherapist is to promote a healthy lifestyle and by investing in studying and giving importance to situations that can be prevented and successfully rehabilitated, the problem of gluteal amnesia is solvable. That is why it is very important to educate a physiotherapist to evaluate the patient holistically, because even 'little things' like dead butt syndrome that have consequences that can be very serious for the smooth conduct of daily activities of life can be removed in a timely manner.
