Gluteal Amnesia: Causes and Fixes

December 19, 2025

If you spend a lot of your day sitting, you might be familiar with gluteal amnesia. While “sleeping butt syndrome” might sound funny, this condition is a common cause of pain and discomfort that can impact your daily life. At Greiner Physical Therapy, we often treat patients in Speonk, NY, who are dealing with the effects of weak or inactive gluteal muscles.

Understanding gluteal amnesia is the first step toward finding relief. It happens when your gluteal muscles—the ones in your buttocks—forget how to activate properly. This forces other muscles, like those in your lower back and hamstrings, to work overtime. Over time, this imbalance can lead to pain, poor posture, and an increased risk of injury. This guide will walk you through what causes gluteal amnesia and what you can do to wake up those sleepy glutes for good.

What is Gluteal Amnesia?

Gluteal amnesia, also known as “dead butt syndrome,” is a condition where your gluteus medius, one of the three main muscles in your buttocks, stops firing correctly. Prolonged sitting can inhibit these muscles, causing them to become weak and underactive. When your glutes don’t do their job, your body compensates by relying on other muscles to stabilize your pelvis and support movement. This compensation often leads to strain and pain, particularly in the lower back and hips.

Many people in the Speonk area who work desk jobs or have a sedentary lifestyle come to us with symptoms related to this condition. Recognizing the signs is key to addressing the problem before it causes more significant issues.

Common Causes and Symptoms of Gluteal Amnesia

The primary cause of gluteal amnesia is a sedentary lifestyle. Spending hours sitting at a desk, on the couch, or in a car can lead to tight hip flexors and weak glutes. When your hip flexors are tight, they can prevent your glutes from activating fully.

Other contributing factors include:

  • Poor posture: Slouching or sitting with an arched back can contribute to muscle imbalances.
  • Lack of varied movement: Not engaging in activities that specifically target the glutes can cause them to weaken over time.
  • Incorrect exercise form: Performing exercises like squats and lunges with improper technique can reinforce poor muscle activation patterns.

The symptoms of gluteal amnesia can vary, but common signs include:

  • Pain in the lower back, hips, or knees
  • Numbness or a tingling sensation in the buttocks
  • Weakness when trying to stand up, climb stairs, or run
  • An anterior pelvic tilt, where your pelvis tilts forward, causing an exaggerated curve in your lower back

If you’re experiencing these symptoms, a physical therapist can help diagnose the issue and create a plan to resolve it.

How to Test for Gluteal Amnesia at Home

You can perform a simple test to check if your glutes are firing correctly. The Trendelenburg test is a common method used by physical therapists to assess gluteal strength.

Here’s how to do it:

  1. Stand in front of a mirror with your feet hip-width apart.
  2. Lift one foot off the ground, balancing on the other leg.
  3. Observe your hips in the mirror.

If the hip on the side of your lifted leg drops, it’s a sign that the gluteus medius on your standing leg is weak. This indicates that your glutes are not providing adequate stabilization, which is a hallmark of gluteal amnesia. While this test is a good indicator, it’s always best to get a professional evaluation for an accurate diagnosis.

Exercises to Activate Your Glutes

Reawakening your glutes involves a combination of stretching tight muscles and strengthening the weak ones. At Greiner Physical Therapy, we tailor exercise programs to meet each patient’s specific needs.

Here are five effective exercises to help you combat gluteal amnesia:

1. Glute Bridge

This is a foundational exercise for activating the glutes.

  • Lie on your back with your knees bent, feet flat on the floor, and arms by your sides.
  • Engage your core and squeeze your glutes to lift your hips toward the ceiling.
  • Hold for a few seconds at the top, then slowly lower your hips back down.
  • Aim for 3 sets of 15 repetitions.

2. Clamshells

Clamshells are excellent for isolating and strengthening the gluteus medius.

  • Lie on your side with your knees bent at a 45-degree angle and your heels together.
  • Keeping your feet touching, lift your top knee as high as you can without rocking your hips back.
  • Hold for a moment, then lower your knee back down.
  • Complete 3 sets of 15 repetitions on each side.

3. Donkey Kicks

This exercise targets the gluteus maximus and helps improve hip extension.

  • Start on all fours with your hands under your shoulders and your knees under your hips.
  • Keeping your knee bent, lift one leg behind you until your thigh is parallel to the floor.
  • Squeeze your glute at the top of the movement.
  • Lower your leg back to the starting position.
  • Do 3 sets of 15 repetitions on each leg.

4. Fire Hydrants

Fire hydrants work the gluteus medius and minimus, which are key for hip stability.

  • Begin on all fours.
  • Keeping your knee bent, lift one leg out to the side, like a dog at a fire hydrant.
  • Lift as high as you can without shifting your weight.
  • Lower your leg back down slowly.
  • Perform 3 sets of 15 repetitions on each side.

5. Hip Flexor Stretch

Stretching tight hip flexors is crucial for allowing your glutes to activate properly.

  • Kneel on one knee with your other foot forward, creating a 90-degree angle with both knees.
  • Gently push your hips forward until you feel a stretch in the front of your kneeling leg’s hip.
  • Hold for 30 seconds, then switch sides.
  • Repeat 3 times on each leg.

Take the Next Step Toward a Pain-Free Life

Dealing with gluteal amnesia can be frustrating, but you don’t have to manage it alone. With the right approach, you can strengthen your glutes, correct muscle imbalances, and live without pain. Incorporating targeted exercises and making simple lifestyle changes, like taking regular breaks from sitting, can make a significant difference.
