Gait Abnormalities
Gait abnormalities refer to deviations from normal walking patterns and can arise from various factors including neurological, musculoskeletal, or systemic conditions. These abnormalities can affect the speed, rhythm, and coordination of walking, impacting an individual’s mobility and quality of life. Identifying and addressing gait abnormalities is crucial for proper diagnosis and treatment of underlying conditions.
Gait” means the way a person walks. Abnormal gait or gait abnormality occurs when the body systems that control the way a person walks do not function in the usual way. In some cases, gait abnormalities may clear up on their own. In other cases, an abnormal gait may be permanent.
Types of Gait Abnormalities –
There are several different types of gait abnormalities, the most common include:
• Antalgic gait: An antalgic gait is the result of pain. It’s the most common type of abnormal gait. It makes you limp (avoiding stepping with or putting pressure on your affected leg or foot).
• Propulsive gait (Parkinsonian gait): This type of gait affects people diagnosed with parkinsonism or Parkinson’s disease. Characteristics of a propulsive gait include a stooping, rigid posture and your head and neck bending forward. Your steps are usually short and fast to maintain your center of gravity (festinating gait).
• Scissors gait: This type of gait gets its name because your knees and thighs hit or cross in a scissors-like pattern when you walk. Your steps may be slow and small. This type of gait usually affects people diagnosed with spastic cerebral palsy.
• Spastic gait (hemiplegic gait): A spastic gait causes you to walk with one stiff leg. When you lift that leg to walk, it either drags or swings around in a semicircular motion (circumduction). This type of gait is common among people diagnosed with cerebral palsy, multiple sclerosis or hemiplegia.
• Steppage gait (neuropathic gait): This type of gait causes a high step, where you elevate your hip to lift your leg higher than normal. Your foot may appear floppy when it drops. Your toes usually point down and scrape the ground when you walk. Muscle atrophy or a peroneal nerve injury (like from spinal stenosis or a herniated disc), can cause a steppage gait.
• Waddling gait: A waddling gait causes you to exaggerate the movement of your upper body, which creates a waddling or duck-like walk. Progressive muscular dystrophy or hip dislocation present from birth can produce a waddling gait.
• Crouching gait: A crouching gait causes your ankles, knees and hips to flex while you walk. It can look like you’re about to bend down as you’re walking. Your toes may drag. This type of gait is common if you have cerebral palsy.
Other types of gait abnormalities include:
• Ataxic gait: This type of gait occurs with cerebellar degeneration. It causes irregular steps that affect your ability to walk in a straight line when you walk heel to toe. You may feel unsteady if you have an ataxic gait.
• Shuffling gait: Shuffling is walking without lifting your feet completely off the ground. It causes your feet to drag. You may shuffle if you feel off balance or have an injury that prevents you from lifting your feet off the ground when you walk.
• Lurching gait: A lurching gait is common among people affected by paralysis or weakness of the gluteus area (the muscles near your hips and butt). It causes a slow and long stride. Your upper body can jerk forward or backward to lessen the weight on your affected leg.
Symptoms of Gait Abnormalities:
Signs and symptoms of gait abnormalities vary based on which type of abnormality you’re experiencing. Some of the most common symptoms include:
• Limping:
Uneven weight distribution or favoring one side while walking.
• Instability:
Feeling unsteady or off-balance during walking.
• Difficulty initiating movement:
Trouble starting to walk due to stiffness or weakness.
Causes of Gait Abnormalities:
There are a lot of possible causes of and contributing factors to gait disorders or abnormalities. The most common causes include:
• Neurological Conditions:
Disorders affecting the brain or spinal cord, such as stroke, Parkinson’s disease, or neuropathy.
• Musculoskeletal Disorders:
Conditions like osteoarthritis, fractures, or muscle weakness due to injury or degeneration.
• Sensory Impairments:
Loss of sensation in the feet or legs, as seen in diabetic neuropathy.
Risk Factors for Gait Abnormalities:
• Age:
Older adults above 60 are more prone to gait abnormalities due to age-related changes in musculoskeletal and neurological function.
• Chronic Health Conditions:
Diabetes, stroke, or Parkinson’s disease increase the risk of developing gait abnormalities.
• Medications:
Certain medications can affect balance and coordination, contributing to gait problems.
Complications of Gait Abnormalities:
The complications of gait abnormalities could include:
• Fall Risk:
Individuals with gait abnormalities have a higher risk of falls, leading to injuries such as fractures or head trauma.
• Reduced Mobility:
Gait abnormalities can limit a person’s ability to perform daily activities independently, affecting their quality of life.
Diagnosis of Gait Abnormalities:
• Medical History and Physical Examination:
Assessing symptoms, previous injuries, and conducting a thorough examination of gait patterns.
• Neurological Evaluation:
Testing reflexes, muscle strength, coordination, and sensation to identify underlying neurological conditions.
• Imaging Studies:
X-rays, MRI, or CT scans may be ordered to evaluate musculoskeletal structures or detect abnormalities in the brain or spinal cord.
• Electrodiagnostic Tests:
Nerve conduction studies or electromyography (EMG) can assess nerve function and muscle activity.
Treatment of Gait Abnormalities:
• Physical Therapy:
Tailored exercises to improve strength, flexibility, balance, and coordination.
• Assistive Devices:
Canes, walkers, or orthotic devices may be prescribed to provide support and improve stability while walking.
• Medications:
Depending on the underlying cause, medications such as muscle relaxants, pain relievers, or medications to manage neurological conditions may be prescribed.
• Surgical Interventions:
In cases of severe musculoskeletal abnormalities or nerve compression, surgical procedures may be necessary to correct the issue.
• Gait Training:
Learning techniques to improve walking patterns and reduce the risk of falls under the guidance of a physical therapist.
• Management of Underlying Conditions:
Treating the underlying cause, such as managing diabetes or optimizing medication regimens for neurological disorders, can help improve gait abnormalities.
Prevention –
You can’t prevent gait abnormalities caused by an underlying medical condition. You can reduce your risk of injury by:
• Wearing protective equipment when playing sports or working at your job.
• Listening to your body and taking breaks or stopping activities when you feel sore.
• Resting after an injury to prevent further irritation or damage.
• Training for strenuous activities by using a proper technique, strengthening your muscles and increasing your flexibility.
• Getting your vision checked regularly.
Conclusion –
Gait abnormalities encompass a range of deviations from normal walking patterns and can result from various underlying conditions affecting the neurological, musculoskeletal, or sensory systems. Recognizing the symptoms, identifying the underlying cause through thorough evaluation, and implementing appropriate treatment strategies are crucial in managing gait abnormalities and improving mobility and quality of life for affected individuals.
