Trendenlenburg sign/gait or also known commonly as hip drop is one of the body’s many imbalances that may occur due to one sided weakness of the hip stabilising muscles. The hip stabilising muscle mainly involved is the gluteus medius muscle, and its secondary support muscles the gluteus minimus and tensor fascia latae (TFL) muscles that also carry out hip stabilisation functions.
Hip drop is particularly important to be addressed and fixed in people who are highly active and participate in high impact and demanding sports, such as running, marathons, athletes, soccer players, etc. due to the nature of the high demands on the joints and muscles of their lower body. If hip drop becomes a sustained and ongoing problem, it could potentially risk the athlete’s joint integrity and predispose them to muscular strain or even tear. For most of us who aren’t highly trained athletes, correcting a hip drop will mean that we will benefit from a better gait, less foot, knee, hip and lower back pain because it will reduce the compensation that occurs in our body. We will benefit in a way such that our balance will improve, our joint mobility will improve, and our control of our lower limbs will be enhanced. These reasons become more vital as we age, and for those of us who don’t spend a lot of time exercising and being active.

Causes of weak gluteus medius/hip drop:
– Direct trauma or acute trauma to the nerves that supply the muscle, direct damage to the muscle like a contusion or laceration, or a broken hip to name a few.
– Chronic causes: these would be the more common causes and risks of hip drop/Trendelenburg gait/weak gluteus medius. Commonly found in athletes who participate in endurance sports, distance running or triathlons, etc. Contributing factors include poor strength and flexibility of the joints and muscles, and failure to warm up properly because it sets a poor foundation for the muscles and tendons in the joints to perform optimally. In other words, poor strength and flexibility, and warm up of the joints, muscles and tendons will increase the risk of injury later on.
– Malalignment issues: joint fixations will limit full range of motion and hence the muscles that control those joints will not be working properly causing the muscle to have faulty patterns over time due to altered neuromuscular action. These malalignment issues often occur through the kinetic chain in the pelvis, the sacroiliac joints, the hip joints, lumbar spine, the knees and feet.
– Tight muscles in specific regions throughout the body will cause compensation patterns to occur through the kinetic chain. For instance, tight quadratus lumborum muscles on one side of the body will cause a pull on the ilia bone and prevent full range of movement through the joint. This inevitably will put more stress on the opposite side of the body to pull the slack and do more work, and for the same side of the body, the muscles that are suppose to be working effectively (in this case the gluteus medius) will tend to lose its muscular firing ability and function. Thus causing the gluteus medius to become the weaker muscle compared to its twin on the other side of the other hip, and this inevitably leads us to our hip drop problem if the underlying problem is not fixed soon enough.
How to diagnose hip drop:
On of the classical sign that will show up positive for hip drop is the Trendelenburg sign. To perform the Trendelenburg test, the practitioner will get the patient to stand on one leg for about 30 seconds or more, instructing the patient to try not to lean to one side. A positive Trendelenburg sign is indicated when the patient’s non-weight bearing pelvis drops down. This will show the examining practitioner that the patient does have gluteus medius muscle weakness that causes hip drop.
However, a positive Trendelenburg sign could also indicate other few possibilities such as:
– superior gluteal nerve palsy that may have happened due to trauma or disease
– lumbar disc herniation
– Legg-Calve-Perthes disease
So it is highly advisable that you get assessed by a qualified Chiropractor, Doctor or other physical therapist to rule out any of these other more serious and complicated issues.
What you can do about hip drop
After you have been properly diagnosed, you could start your rehabilitative exercises immediately to correct the hip drop. There are many exercises and stretches that you could do at the gym, at the park or even in the comfort of your own home. The following are the best recommended exercises that you could easily do that is fast and effective, sorted from easiest to more challenging:
*Remember that the rehabilitative system works like this: 15 repetitions, 3 sets
Lateral leg raises: Lateral leg raises are one of the most easiest exercises to warm up and get the hip joint moving and the muscles that we need to exercise working. It’s highly recommended to start your rehabilitative program with these lateral leg raises, even if your at an intermediate level. To do this exercise, all you need to do is lay down on a flat surface and focus your mental energy on the muscles that need to be activated (that is your gluteus medius) and the motion that you are about to do with fluidity and control
- lay on your side with your hip joints directly above each other – and keep the hip joints level
- engage and activate your core muscle. Raise your top leg up into the air, maintaining the same plane as your bottom leg (don’t let it sway to the front or the back)
- as you bring your leg up into the air, you could intensify this exercise by adding in some hip abduction midway through and ending in about 80% hip abduction at your finished position. This additional hip abduction will get all of the fibres of your gluteus medius muscle firing and working for better neuromuscular activation.
- bring that leg down into neutral position to where you have started. Remember that it is important to control the motion of lowering your leg down and not just letting that leg drop down
Lateral step ups: these could be done on just a step/stairway or even a little stable stool that you have at home. The idea of this exercise is activation of your gluteus medius whilst you go through the range of motion of lifting your body weight onto that weight bearing hip/leg. Remember to do these repetitions in a controlled and fluid manner.
- with your knee resting on the platform, concentrate on activating your gluteus medius muscle, hoist your body weight on this hip so that your standing up right.
- keeping your body weight propped up on the supported leg, let your unsupported hip dip down whilst still maintaining the contraction of the gluteus medius on the weight bearing hip.
- With your gluteus medius still activated on the weight bearing hip, tip your dipped hip back to neutral position
- Step down. Repeat 15 times, 3 sets.
Lateral band walks: you will need an exercise band for this. You could easily purchase one from your sports retailer, eBay, or gymnastics/pilates studios. These lateral band walks will challenge your mobility and coordination aswell as your gluteus medius strength.
- with your hips slightly bent, but the top of your collarbone not passing your knees. Engage in the first position as the image suggests
- Consciously activate your gluteus medius muscle and start side stepping, keeping your movements controlled and fluid
- Follow the hind leg to the leg you used to step out first.
- Repeat 15 times, 3 sets.
Single leg squats: once you have been able to regain the proprioception and the muscular control of your gluteus medius muscles and its supporting muscles, you can try these killer single leg squats. Hang onto some support for balance if you are a little bit off balance at first. Not only does this single exercise work on strengthening up the gluteus medius muscle, it also improves your proprioceptive neuromuscular pathways to – in other words, improve your balance.
- Start off in standing position – activating your gluteus medius muscle
- Squat down on the one leg slowly – maintaining contraction and activation of the gluteus muscle. Remember knees do not go past toes.
- stay down as low as you can (try to go lower everytime into the squat position) for a 3 second hold.
- Stand up from this position, still engaging the gluteus medius muscle
- Repeat 15 repetitions, 3 sets

If you are concerned and want to gain further insight, it is highly advisable that you seek a registered Chiropractor or physical physician to evaluate, assess and conduct you with your concerns.
