Walking and balance issues are among the most significant motor challenges faced by individuals with Parkinson’s disease. These problems occur because the brain lacks the dopamine needed to coordinate complex, automatic movements. In a healthy nervous system, walking is largely an unconscious activity, but in Parkinson’s, it becomes a conscious and often effortful task. As the condition progresses, changes in gait and stability can impact independence and increase the risk of injury. Understanding these specific patterns is vital for early intervention and for implementing safety strategies that help maintain mobility.

Changes in walking patterns and gait
A parkinsonian gait is a distinct pattern of walking that often develops early in the disease and becomes more pronounced over time.
Shuffling and small steps
One of the most common early signs is a reduction in step length. Instead of a fluid heel to toe motion, individuals may begin to shuffle, where the feet stay close to the ground and land flat. This shuffling often occurs because the brain is struggling to regulate the size and speed of movement. Over time, steps may become increasingly small and rapid, a phenomenon known as festination, which can make a person feel as though they are being pulled forward by their own momentum.
Reduced arm swing
During normal walking, the arms naturally swing in opposition to the legs to help maintain balance and momentum. In Parkinson’s, this automatic arm swing is often reduced or lost entirely, typically beginning on one side of the body. This loss of movement can make the walk appear stiff and can further compromise a person balance when navigating turns or uneven surfaces.
Postural instability and balance
Postural instability refers to a loss of the automatic reflexes that keep us upright when we shift our weight or are pushed off balance.
This symptom is a leading cause of falls in advanced Parkinson’s. In a clinical setting, we often test this by gently pulling a patient backward to see if they can catch themselves with a single step. For someone with Parkinson’s, this corrective step is often delayed or absent, a condition called retropulsion. This instability is frequently worsened by a stooped posture, where the body leans forward from the waist, shifting the centre of gravity and making it harder for the person to recover their balance if they trip.
Freezing of gait
Freezing is perhaps the most distressing walking problem, where a person feels as though their feet are temporarily glued to the floor.
Freezing of gait typically lasts for a few seconds but can occur suddenly, especially when a person is:
- Starting to walk (start hesitation)
- Turning in a tight circle or close quarters
- Walking through a doorway or a narrow passage
- Approaching a crowded or cluttered area
- Feeling stressed or rushed
This sudden stop in movement while the upper body is still moving forward creates a significant risk of falling. Many people find that using external cues, such as stepping over a line on the floor or walking to a rhythmic beat, can help the brain re initiate the walking signal and break the freeze.
Sensory and motor planning challenges
Walking is not just about muscle strength; it requires the brain to process sensory information and plan movements ahead of time.
Parkinson’s disrupts the way the brain integrates information from the eyes, the inner ear, and the sensors in the joints. This can lead to difficulty multitasking, such as walking and talking at the same time. When the brain has to focus on two tasks, the automatic nature of walking fails, leading to a slower pace or a freeze. Physiotherapy focuses on teaching patients to break down the walking cycle into conscious, deliberate steps, which bypasses the damaged automatic pathways in the basal ganglia.
Emergency guidance
While walking changes are usually slow to develop, sudden and acute shifts in mobility or balance require immediate medical attention.
If you experience sudden and severe neurological shifts, call 999 immediately.
Seek urgent medical help if you notice:
- A sudden and total inability to walk or stand that was not previously present
- Rapid onset of severe confusion, delirium, or a loss of consciousness
- Signs of a stroke such as facial drooping or weakness on one side
- A severe fall that results in a head injury or an obvious limb deformity
- Acute difficulty with swallowing or a sudden change in breathing
To summarise
Walking and balance problems in Parkinson’s disease manifest as a combination of shuffling gait, reduced arm swing, and postural instability. These issues are caused by the brain inability to automatically coordinate movement, leading to challenges like festination and freezing of gait. While these symptoms significantly increase the risk of falls, they can be managed through a combination of tailored medication, environmental adjustments, and specialized physiotherapy. By focusing on deliberate movements and using sensory cues, many individuals can improve their stability and maintain their independence for a longer period.
Why do I feel like I am being pulled forward when I walk?
This is known as festination. It happens when your centre of gravity is too far forward due to a stooped posture, and your feet take small, fast steps to try and catch up with your trunk.
Can special shoes help with shuffling?
Shoes with a firm sole and good support are helpful, but avoid overly grippy rubber soles if you are prone to freezing, as they can make it harder to slide the foot forward during a shuffle.
Does medication help with balance?
Dopamine replacement therapy is very effective for tremors and stiffness, but it often has a more limited impact on balance and postural instability. Physical therapy is the primary treatment for these specific issues.
What should I do if my feet freeze?
Stop, take a breath, stand tall, and try to shift your weight from side to side. You can also try to imagine stepping over a hurdle or have someone place their foot in front of you to use as a visual cue.
Is it safe to use a walker?
Yes, but it should be recommended by a physiotherapist. Some types of walkers can actually increase the risk of falling forward if they are not used correctly by a person with Parkinson’s.
Why does my walking get worse when I am in a crowd?
Crowded environments provide a lot of visual and sensory distraction. This forces the brain to process too much information, which interferes with the conscious effort required to walk when the automatic system is damaged.
Can exercise prevent these problems?
While exercise cannot stop the disease, regular aerobic activity and balance training like Tai Chi or specialized Parkinson’s boxing can significantly improve your resilience and lower your fall risk.
