What Is Apraxia?

Apraxia is a neurological disorder in which a person has difficulty performing learned, purposeful movements despite having the basic physical ability to perform them. The problem is not simply a lack of muscle strength. Instead, the brain has difficulty organizing or executing the motor plan needed to complete an intended action.

This distinction is important.

Imagine being asked to perform a familiar action. You understand the instruction and know what the action should look like, but translating that intention into the correct sequence of movements becomes difficult.

Depending on the type and location of neurological damage, apraxia can interfere with actions involving the arms, hands, face, speech or more complex motor activities.

For patients and caregivers, this can sometimes be confusing because the difficulty may look like weakness, poor coordination or even hesitation. A neurological assessment is needed to determine what is actually limiting the movement.

What Causes Apraxia?

Acquired apraxia occurs when areas or networks of the brain involved in planning and executing learned movements are damaged. Stroke is a major cause, but apraxia can also occur after traumatic brain injury and in association with some neurological and neurodegenerative diseases.

The symptoms therefore depend partly on where and how extensively the brain has been affected.



For someone recovering from a stroke, for example, several problems may exist at the same time. There may be muscle weakness, altered sensation, impaired balance, abnormal muscle tone, coordination difficulties and problems with motor planning.

This is why identifying apraxia matters during rehabilitation. Improving muscle strength alone may not address a movement problem when part of the difficulty involves the way the brain plans and organizes that movement.

What Are the Motor Symptoms of Apraxia?

Motor apraxia can make familiar movements unexpectedly difficult. A person may know what they want to do but have trouble organizing the movements required to accomplish it.

Depending on the type of apraxia and the underlying neurological condition, difficulties may include:

• Performing a learned movement on command
• Correctly sequencing several movements
• Imitating a movement demonstrated by another person
• Using familiar objects appropriately
• Positioning a limb correctly for an intended action
• Starting or completing complex purposeful movements
• Performing everyday activities that previously felt automatic

One form, ideomotor apraxia, affects the ability to correctly perform or imitate learned gestures on command. Other forms can interfere with the conceptual organization or sequencing of more complex actions. These distinctions can be clinically important, but from the patient's perspective the practical consequence is often simpler: movements that once required little conscious thought may suddenly require much more effort and guidance.

Can Apraxia Affect Walking?

Apraxia and walking problems can occur together, but not every person with apraxia has difficulty walking. Gait apraxia refers more specifically to a higher-level neurological walking disorder in which the brain has difficulty organizing or initiating the movements required for effective gait.

This distinction prevents two different problems from being confused.

A person with limb apraxia may have difficulty performing purposeful movements without necessarily having gait apraxia. Conversely, a person with a higher-level gait disorder may have significant difficulty initiating or organizing walking.

Walking itself is remarkably complex. The brain must organize weight shifting, step initiation, foot clearance, forward movement of the leg, foot placement, balance and preparation for the next step. When neurological disease disrupts higher-level control of this sequence, walking may become slow, hesitant or inefficient.

What Does Gait Apraxia Look Like?

Gait apraxia can involve difficulty initiating walking, short steps, reduced foot clearance and problems coordinating the sequence required to move forward. The exact walking pattern depends on the underlying neurological condition, so gait apraxia should be evaluated rather than diagnosed from appearance alone.

Some patients may appear as though their feet are reluctant to leave the floor. Starting to walk may be particularly difficult, and turning can increase instability.

The term magnetic gait is sometimes encountered in this context. It describes a pattern in which the feet appear to remain close to or “stuck” to the floor. This type of gait is particularly associated with normal pressure hydrocephalus, NPH, where gait disturbance is often one of the earliest and most prominent symptoms. Research on NPH describes features including short steps, reduced foot clearance, start hesitation and instability while turning.

This does not mean that magnetic gait and apraxia are interchangeable terms. In fact, the terminology surrounding gait apraxia, frontal gait and related higher-level gait disorders is not completely uniform in neurological literature.

That is another reason why a new or unexplained change in walking deserves professional neurological assessment.

Gait Apraxia vs. Ataxia: What Is the Difference?

Gait apraxia and ataxia can both make walking difficult, but they describe different neurological problems.

The outward appearance of neurological gait disorders can overlap. A clinician therefore looks beyond the way someone walks and considers neurological examination, medical history, imaging when indicated and other findings before identifying the cause.

Why Gait Apraxia Matters in Older Adults

A new walking problem in an older adult should not automatically be attributed to aging.

Gait can change for many reasons, including weakness, arthritis, medication effects, sensory loss, Parkinsonian disorders, previous stroke and other neurological conditions. Higher-level gait disorders are another possibility.

Normal pressure hydrocephalus is particularly important in this discussion because gait and balance impairment commonly appear early, often alongside cognitive and urinary symptoms as the condition progresses. Some gait impairments associated with NPH may improve when the underlying condition is appropriately treated.

A change such as increasing difficulty starting to walk, unusually short steps, repeated instability or a noticeably altered gait pattern therefore deserves assessment rather than simply being accepted as part of getting older.

How Are Apraxia and Gait Problems Treated?

Treatment depends on the type of apraxia and, most importantly, its underlying cause. Rehabilitation may include physical therapy, occupational therapy and other targeted approaches designed to help a person perform functional movements more effectively. There is no single rehabilitation program that is appropriate for every person with apraxia.

When walking is affected, rehabilitation may also address the specific factors limiting gait.

Depending on the individual, a rehabilitation program may work on:

• Step initiation and repeated walking practice
  
• Balance and postural control
  
• Weight shifting
  
• Lower-limb coordination
  
• Strength and endurance
  
• Sensory and proprioceptive input
  
• Functional activities such as standing, turning or climbing stairs
  
• Strategies that help the patient complete everyday movements more independently

Importantly, rehabilitation should not assume that every walking problem in a person with apraxia is caused by apraxia. After a stroke or another neurological injury, several impairments may contribute to the same abnormal gait.

The rehabilitation team therefore needs to identify what is preventing this particular person from walking effectively.

Where Does Just Walk Fit Into Neurological Gait Rehabilitation?

When a neurological condition affects walking and a clinician determines that active gait practice is appropriate, repeated functional movement can become an important part of rehabilitation.

Just Walk™ is a wearable neuromotor rehabilitation device designed to support gait retraining in people with neurological impairments, including stroke, Parkinson’s disease, multiple sclerosis and traumatic brain injury. It is not a treatment for apraxia itself. Instead, its relevance is to the gait and neuromotor rehabilitation needs that may accompany neurological injury or disease.

The fully mechanical system works during the gait cycle. It assists foot lift at step initiation and provides adjustable resistance as the leg moves forward. Chaban Medical describes this combination as a way of increasing proprioceptive input while supporting motor learning and active functional movement.

That distinction matters.

A conventional mobility aid is primarily designed to help compensate for difficulty walking. Just Walk is designed as a neuromotor rehabilitation device, meaning the patient remains actively involved in performing and repeatedly practicing the movement.

Because it is wearable, gait practice can also be incorporated into functional activities such as walking, lateral movement and stair climbing when these activities are appropriate for the patient's abilities and rehabilitation plan.



For someone recovering from a neurological injury who has both motor-planning and gait difficulties, the first question is therefore not simply, “Does this device treat apraxia?” It does not.

The more useful question is: Which aspects of this person's walking are impaired, and could active gait retraining form part of the rehabilitation strategy?

Moving From Intention Back to Movement

Apraxia demonstrates just how much of movement happens in the brain before a muscle ever contracts. After neurological damage, knowing what you want to do and physically having the strength to do it may no longer be enough to produce a smooth, purposeful movement.

When walking is also affected, rehabilitation needs to look beyond strength alone. Motor planning, coordination, sensory feedback, balance and repeated functional practice may all need to be considered.

For patients recovering from neurological injury, the appropriate approach depends on the cause of the movement problem and the individual's abilities. A physician, physical therapist or rehabilitation professional can assess the gait impairment and determine whether gait retraining, including technologies such as Just Walk, is appropriate.
