The weakening of the hip girdle muscles, which is most frequently caused by myopathy and is most distinctively caused by muscular dystrophy, results in a myopathic gait.
If your child needs surgery or casting, our Fracture Care Clinic opens every day and you do not need an appointment. Surgery rooms get scheduled every morning, so your child receives the care and attention they need right away.
Your upper thigh and hip muscles become weak, which results in a myopathic gait. You wobble from side to side, your hip dropping with each stride, trying to make up for the weakness.
Myopathic Gait in Pregnancy
A myopathic gait has several reasons, one of which is pregnancy. Pregnancy causes a number of physical changes in your body that have an impact on how you walk. It increases the synthesis of the hormone relaxin as one method of getting ready to give birth. Your pelvic muscles and joints will relax as a result, making it simpler for a baby to pass through. When you are pregnant, you also put on weight. You must slightly incline your back since your center of gravity is altered by the majority of it being in your belly. After giving delivery, your gait should return to how it was before becoming pregnant.
Myopathic Gait in Muscular Dystrophy
A hereditary disorder called Duchenne muscular dystrophy (DMD) results in progressive muscle weakening. It’s one of four disorders brought on by a change in the dystrophin protein, which keeps muscle cells bound together. By the time they reach school age, children with DMD walk with a waddling stride. A milder kind of DMD called Becker muscular dystrophy (BMD) can also result in a waddling gait. Compared to DMD, it is frequently diagnosed later in life. The progress is typically slower and less predictable. DMD and BMD primarily impact boys. By the time they are 12 years old, most DMD patients need to use a wheelchair. Prior to that, walking can be assisted by mobility aids. These incorporate:
- Supporting ankle and foot braces
- Achilles tendon stretching braces used at night
- An upright walker
- wheelchairs with an adjustable height for standing
Myopathic Gait in Toddlers
Under the age of three, a myopathic gait is typical. When a youngster is first starting to walk, their feet are spread out and pointed out. As they take several quick steps, this aids in maintaining their equilibrium. Ask your child’s physician about it if they are older than 3 and still walk with a myopathic gait. Among the illnesses that might manifest in children older than 3 as having a myopathic gait are:
- Developmental dysplasia of the hip
- A muscle sickness, such as DMD
- Cerebral palsy is an illness that disturbs movement and balance
- Lower back curvature that is noticeably more inward, or lumbar lordosis. In children, this often fades away on its own.
Myopathic Gait in Spinal Muscular Atrophy
A genetic condition called spinal muscular atrophy (SMA) causes the spinal cord’s nerve cells to die. The peripheral nervous system, the central nervous system, and voluntary muscular movements are all impacted. Mild to severe SMA symptoms are possible. In general, the severity of the ailment increases with the onset of symptoms. Autosomal dominant spinal muscular atrophy, lower extremity-predominant type 2 is one kind of SMA. Early infancy is when signs of this illness first manifest, mostly affecting the thigh muscles. Additional signs include:
- Delayed walking
- Difficulty walking
- Foot deformities
- Loss of some reflexes
How Is Myopathic Gait Diagnosed?
Your doctor will examine you physically and discuss your symptoms with you. They could also verify:
- Muscle power, tone, and synchronization
- Check your spine and neck for abnormalities
- determine your risk of falling
- Your heart rate while sitting, standing, and laying down
- Your vision
- In the case of neurological conditions like muscular dystrophy
- for arthritis
Your doctor may recommend additional testing or imaging procedures based on the results.
How Is Myopathic Gait Treated?
The etiology of a waddling gait will determine the course of treatment. Some illnesses could get better on their own. Other medical possibilities include:
- Balance aids like canes and walkers
- Physical treatment helps improve flexibility, balance, and strength
- steps to prevent falls
- To aid in proper foot alignment, use leg braces or splints.
- surgery or artificial limbs
The weakening of the hip girdle muscles, which is most frequently caused by myopathy and is most distinctively caused by muscular dystrophy, results in a myopathic gait. When walking, the pelvis has to be stabilized by the hip abductor muscles, particularly the gluteus Medius. Sometimes this walking style is referred to as a gluteus Medius gait. Because the hip abductors on the opposite side are weak, Trendelenburg’s sign causes an irregular pelvic drop on the side of the swing leg. As the stance leg adducts, the hip on the afflicted side juts laterally rather than remaining in a stable posture. In contrast to the hip on the swing side, which sags downward, the stance side hip moves laterally.
When there is bilateral weakness, the hip on the side of the swing leg droops, causing an accentuated pelvic swing with every stride and a “waddling” gait. Exaggerated pelvic swings are frequently referred to as “sexy” gaits because they mimic runway models’ strides. This walking pattern can take on odd shapes, especially with FSH dystrophy. The patient’s shoulders are flung back and his or her pelvis is shoved forward as they walk. Particularly prevalent in people with facioscapulohumeral muscular dystrophy is this gait style. The little child in the video has a waddling gait as a result of pelvic girdle dysfunction. Also take note of the protruding belly, lumbar hyperlordosis, and forward-facing shoulders. In order to prevent the patient from falling forward due to weak back and hip extensors, this posture shifts the center of gravity behind the hips.
