‘Dead butt’ syndrome linked to prolonged sitting, experts say — 30‑second self‑test can help detect weakened glutes
Health specialists warn that sedentary work and more time spent at home may be leaving glute muscles inactive, increasing risks of back, hip and knee problems; simple checks and targeted exercises can help.
Millions of people who spend most of their work day seated may have weakened buttock muscles — a condition clinicians call gluteal amnesia or, more colloquially, “dead butt” syndrome — that can increase stress on the lower back, legs and joints and raise the risk of painful conditions such as arthritis and sciatica.
Medical specialists say the condition can be symptomless at first, making it easy to miss until secondary problems develop. They are urging people who sit for long periods to check whether their glute muscles are engaging properly and to use simple preventive measures.
Gluteal amnesia occurs when the body stops recruiting the three major glute muscles — which stabilize the hip, lift the leg and rotate the thigh — because they are not regularly used. When the glutes fail to contract normally, other structures including the lower back, leg muscles and hip and knee joints must compensate, which can lead to pain and injury over time, clinicians say.
"In recent years, we've seen a real increase in the number of patients suffering with this issue, which might be in large part due to the rise of working from home," said Dr. Jane Konidis, a specialist in physical medicine and rehabilitation at the Mayo Clinic. "Many people spend whole days sitting in front of a laptop, going from one Zoom meeting to the next, meaning they aren't using their glute muscles enough, which can impact the rest of the body."
Clinicians link gluteal amnesia to a related condition, gluteal tendinopathy, in which the tendons on the outside of the glutes become irritated or damaged. Studies suggest about 15 percent of women and 8 percent of men have gluteal tendinopathy, with the condition most common in people aged 40 to 60.
"The leading causes are a sedentary lifestyle, so sitting for long periods at a desk, or bad posture," said Dr. Chris Seenan, senior lecturer in physiotherapy at the University of Stirling. "Some speculate that the reason more women get this issue is because they are more likely to sit cross‑legged, which can put extra strain on the tendons." He added that when tendons are inflamed the body may reduce gluteal contraction to protect them, shifting load to the legs, feet and ankles and increasing injury risk.
Because the condition can be painless at first, experts recommend a simple at‑home check that takes about 30 seconds. Stand on one leg with the other leg relaxed and dangling; feel the glute muscle on the standing side and then switch. Squeeze the cheek of the standing leg hard. If the muscle does not tense promptly, clinicians say, this could indicate the glute is not engaging normally.
Other early signs can include an achy lower back, stiffness in the glutes when bending, or discomfort during daily activities. Left unaddressed, clinicians say, gluteal amnesia has been associated with osteoarthritis of the knee and hip and with sciatica, a type of nerve pain that can radiate into the legs and buttocks.
Prevention and treatment focus on restoring regular use and strength in the gluteal muscles. Clinicians advise breaking up long periods of sitting by standing or moving briefly every 30 minutes and practising even weight distribution when standing. Strengthening exercises that target the glutes — including squats, lunges, side planks and single‑leg glute bridges — are commonly recommended by physiotherapists.
"These sorts of exercises are great for the glutes," Dr. Konidis said. "But the most important thing is ensuring you're staying mobile. Even just going for a short walk at lunchtime can make a real difference." Dr. Seenan also recommended attention to posture and avoiding habits that place uneven load on the hips.
Official health information and step‑by‑step guidance for glute and leg strengthening routines are available from public health resources such as the U.K. National Health Service and the charity Versus Arthritis, which provide posture advice and exercise demonstrations for people with hip and knee problems.
Clinicians caution that while simple self‑checks and home exercises can help identify and address early gluteal weakness, persistent pain or functional limitations warrant assessment by a health professional. A physiotherapist can evaluate movement patterns, identify tendon irritation or other causes of pain, and design a tailored rehabilitation program that may include strengthening, stretching and activity modification.
As more workers continue to spend large portions of the day seated, specialists say awareness of gluteal amnesia and early preventive action could reduce the burden of related musculoskeletal problems. Staying active, monitoring muscle engagement and seeking professional assessment when pain arises remain the primary measures advised by clinicians.
