On September 24, Ujuhama explained on his YouTube channel's community board, "I tried to recover in secret, but it seems it will take a little more time. In fact, I got gluteal amnesia. I forgot about my glutes, and the nerves are being compressed, so it's so painful that I can't sit." He also added, "Still, I'm slowly seeing signs of improvement."


If you sit for prolonged periods and have low levels of physical activity, you may develop "gluteal amnesia." This condition is also called "dead butt syndrome," "gluteal inhibition syndrome," or "gluteus maximus and hamstring control disorder." Gluteal amnesia occurs when the gluteus maximus fails to function properly, causing other muscles, including the hamstrings, to be overused, which leads to muscle imbalances and pain.


The gluteus maximus connects the upper and lower body and supports the spine and pelvis. Most movements—including walking, running, sitting, and standing up—are linked to the glutes. Because these muscles play a key role in spinal stability and maintaining overall body balance, if they are weakened, the support for the pelvis and spine can decrease. As a result, problems such as herniated discs, hip impingement syndrome, and arthritis may occur.


If you feel no strength in your glutes when lifting your leg while lying face down, or if only your lower back tenses up without your glutes reacting when you arch your upper body, there is a high likelihood that your gluteal function is diminished. Additionally, if your left and right glutes are shaped differently or feel excessively soft, it is important to check for further issues.

Exercise is key to both prevention and treatment. It is important to stimulate weakened gluteal muscles and learn how to use them correctly. Representative exercises include squats, bridges, and hip abductions. Pelvic floor exercises—where you lift and squeeze your anal muscles, slowly counting from one to five before releasing—can also be helpful.



Improving lifestyle habits is also essential. Even if you have to remain seated for long periods, you should stand up and stretch every hour, sit with proper posture without relying on the chair back, and consciously engage your glutes when standing or walking. Instead of using elevators or escalators, develop a habit of taking the stairs to continuously strengthen your gluteal muscles in your daily life.
