Why Parkinson’s Patients Walk Slowly?

Ever wonder why Parkinson’s patients walk slowly?

This slowness results from a depletion of dopamine-producing brain cells, leading to ‘bradykinesia,’ a term describing their gradual movements. This loss disrupts the brain’s motor control and influences their daily lives. Yet, ongoing research and treatment advancements hold the promise of improving their mobility.

Let’s learn more about this important feature of Parkinson’s disease.

why Parkinson's patients walk slowly?

Parkinson’s disease is a brain disorder that affects millions of people worldwide. One of the most visible and distressing symptoms of this disease is the slowed and shuffling gait.

In this article, we will explore the reasons behind why Parkinson’s patients walk slow. We will shed light on the underlying biological mechanisms and further discuss the impact of this problem in their daily lives. But before delving into the mechanics of slow walking in Parkinson’s patients, let’s briefly understand the disease itself.

Parkinson’s disease is characterized by a loss of dopamine-producing neurons in the brain. These specialized groups of neurons are abundantly present in a particular area of the brain called the Substantia nigra, a Latin term that means ‘black substance,’ referring to the dark pigmentation of this region.

Dopamine is a neurotransmitter that plays a crucial role in regulating movement and coordination. As dopamine-producing neurons die off, there is a significant reduction in dopamine levels in the brain. This deficiency leads to a severe impact on the movement functions of the brain. As a result, the body shows a range of motor symptoms, including slow movement, muscle rigidity, tremors, and postural instability. These factors collectively contribute to the characteristic slow and unsteady gait seen in Parkinson’s patients.

Bradykinesia – The culprit behind slow walking

Bradykinesia is a term used to describe the slowness of movement that is prevalent in Parkinson’s disease. This feature of the disease affects not only walking but also other everyday activities that involve motor functions. For example, it affects a person’s ability to write, eat, and perform self-care tasks that include bathing, dressing, and grooming.

Parkinson’s patients experiencing bradykinesia often feel like they need to put in a lot of effort to get their bodies to move. This can be frustrating and make them very tired.

Understanding the neurological mechanisms and contributing factors

The root cause of bradykinesia is the disruption of the normal brain circuits that control movement. In a healthy individual, the brain actively receives signals to initiate and coordinate movement. These signals travel through the area that is located at the brain base. This area is named as the basal ganglia. The basal ganglia area of the brain is heavily reliant on dopamine. When dopamine levels are reduced in this area, the messages instructing muscles to contract and relax become impaired. This, as a result, leads to the gradual slowing of movement.

The slowness of movement in Parkinson’s disease can be attributed to several factors that significantly impact a patient’s ability to walk comfortably and confidently. Here are the three such factors.

  1. Muscle rigidity: Stiff and tense muscles further hinder movement. Rigidity makes it difficult for the body to initiate and sustain natural and easy steps.
  2. Loss of arm swing: In Parkinson’s disease, patients often lose the natural swinging of their arms while walking, which provides balance and forward momentum.
  3. Postural instability: Poor balance and a tendency to fall can cause Parkinson’s patients to take shorter and more cautious steps. This postural instability can add to their overall slowness.

Impact on daily life

The slow gait associated with Parkinson’s has profound implications for patients’ daily lives. It can lead to reduced mobility, increased risk of falls, and an overall decline in the quality of life.

Similarly, simple tasks that are easy for most people, like crossing the street or standing up from a chair, can be very hard for those with Parkinson’s disease.

Treatment options

While there is currently no cure for Parkinson’s disease, various treatment options are available to manage its symptoms. The most common and effective approach is medication that helps to replenish dopamine levels or mimic its effects in the brain of a patient. Besides medication, physical therapy and exercise can also improve gait and overall mobility.

Certain mobility aids are also available that are made to help patients regain control of their walking.  


Slow walking in Parkinson’s disease is a multi-faceted problem rooted in the loss of dopamine-producing neurons, which disrupts the brain’s ability to control body movement. Understanding this problem and the factors contributing to it is essential not only for researchers and healthcare professionals but also for the patients and their families facing these challenges daily. While there is no immediate cure, ongoing research and advancements in treatment provide hope for improving the lives of those living with this condition.
