A Guide to Physical Therapy for Neurological Deficits
When it comes to physical therapy for neurological deficits, there is a lot of ground to cover. We'll be looking at everything from head injuries and stroke rehabilitation to cerebral palsy and multiple sclerosis. Regardless of the condition you're dealing with, some general things will hold true for all patients seeking physical therapy treatment. Let's take a closer look at what those are in this comprehensive guide.
It was once thought that the plasticity of the brain was limited. However, we now know that the brain can do remarkable things- adapting to change, injury, aging, and growth with amazing malleability.1 The brain's ability to adapt is what makes physical therapy an integral part of ensuring its optimal health.

To understand how physical therapy can help patients with neurological deficits and other issues related to the head, it's important to first understand a little bit about the brain (and head) and how it works.
The brain is made up of billions of cells called neurons, which send and receive electrical signals. These signals allow us to think, feel, and move. The brain is also divided into different regions, each responsible for specific functions.
Let's review the basic regions:2
Cerebrum: This is the largest region of the brain and is responsible for our higher-level functions, such as reasoning, problem-solving, and planning. It includes:
- The frontal lobe, which controls things like movement and decision-making
- The temporal lobes (sides), responsible for memory and hearing
- The parietal lobe (top middle), which helps us process information about touch, taste, and movement
- The occipital lobe (base of the brain), responsible for interpreting vision
Cerebellum: This region is located under the cerebrum and helps with balance, coordination, and muscle movement.
Brainstem: This region connects the brain to the spinal cord and controls basic functions like breathing and heart rate.
Other Key Areas of the Brain that Help The Body Thrive
- Pineal gland: This small gland is located near the center of the brain and helps to regulate our sleep-wake cycles.
- Pituitary gland: This gland is located at the base of the brain and produces hormones that help us grow, reproduce, and maintain our metabolism.
- Hypothalamus: This area of the brain helps to regulate things like hunger, thirst, body temperature, and blood pressure.
- Amygdala: This almond-shaped region is responsible for our emotions, including fear and aggression.
- Hippocampus: This region helps us form new memories and is essential for learning and recall.
- Basal ganglia: This area of the brain is involved in motor control and coordination.
- Cranial nerves: These are a set of 12 nerves that originate in the brain and provide sensation to the head and face, as well as control movement of face, neck, and other muscles.
These are just a few of the key areas that help us function optimally on a daily basis! As you can see, when something goes wrong with any part of the brain, it can have a major impact on our overall health and well-being.
Keeping Brain Tissue Healthy
Brain tissue is supplied with essential nutrients via the bloodstream and a specialized liquid called cerebrospinal fluid (CSF). This fluid surrounds and cushions the brain, as well as removes waste products.
The blood-brain barrier is a special system that helps to protect the brain from harmful substances in the bloodstream. This barrier is made up of cells that tightly fit together and prevent most large molecules and toxins from entering the brain.
Any blockage or injury that affects the bloodstream and CSF can lead to a wide variety of functional deficits and problems.
Other Important Anatomy of the Head
The bony skull houses and protects the brain, as well as several other important structures including:
- The eyes
- The ears
- The nose
- The mouth and jaw
- The vestibular system (responsible for balance)
- Muscles of the head that allow us to express ourselves, speak, chew, blink, etc.
In short, the brain and surrounding features are an incredibly complex and important system. And when something goes wrong, whether it's due to an injury or a disease, the effects can be devastating.
A focal neurological deficit is a problem with how one or more specific parts of the brain are working. This can be caused by damage to the brain, such as from a stroke or head injury, or it can be the result of a disease like Alzheimer's or Parkinson's. These deficits can cause a wide range of symptoms, depending on which part of the brain is affected, but they are relatively predictable based on which tissues are affected.
Some common symptoms include:
- Paralysis on one side of the body
- Problems with balance and coordination
- Difficulty speaking or understanding speech
- Difficulty reading or writing
- Visual disturbances
The type, location, and severity of the symptom can indicate which part of the brain or nervous system is affected.3 If you or a loved one are experiencing any of these symptoms, it's important to see a doctor right away. A focal neurological deficit can be a serious condition and the sooner it is diagnosed the better.
Potential Underlying Causes Include:
- Traumatic brain injury
- Alzheimer's disease
- Parkinson's disease
- Medication side effects
We will discuss these further in a section below.
A non-focal neurological deficit (NFD) is a problem with how the brain is functioning as a whole and is harder to pinpoint. This can be caused by loss of consciousness, emotional issues, or a transient ischemic attack (mini-stroke).
Some common symptoms include:
- Altered consciousness
- Feeling generally unwell
Many other types of brain dysfunction can occur — some temporary, some permanent. These include:
Traumatic Brain Injury (TBI)
A TBI is an injury to the head that disrupts the normal function of the brain. This can be caused by a fall or impact, a car accident, or a blow to the head. TBI can range from mild (concussion) to severe (coma or vegetative state).
Concussions are common with impact sports, falls, and car accidents. These are typically considered a "mild TBI" since the symptoms tend to resolve after a shorter period of rest. However, sustaining more than one concussion can lead to progressive long term effects over time.
A stroke is a sudden interruption of blood flow to the brain, most often caused by a clot or bleeding. This can lead to damage or death of brain tissue. Common issues after a stroke include movement, vision, and speech problems. What deficits occur depends on which tissues are affected and can vary widely.
Alzheimer's is a degenerative disease that affects memory and cognitive function. Theories for the cause surround genetics, aging, lifestyle factors, and chronic disease that affects blood perfusion of the brain.4
Parkinson's is a degenerative disease that affects movement and coordination. It is caused by the death of neurons in the brain that produce dopamine. The exact reason for why this occurs is unknown, but theories include genetics, environmental factors, and viral infections.5
Anesthesia is administered for surgery and can have both short- and long-term effects on the brain. This most often involves changes in cognition. The exact mechanisms are not well understood, but it is thought that anesthesia affects the neurotransmitters (hormones) in the brain.
Medication Side Effects
Some medications can cause brain fog, confusion, and other problems. Examples include:
- Anticholinergics (used for urinary incontinence, allergies, colds)
- Benzodiazepines (used for anxiety, seizures, insomnia)
- Statins (used for cholesterol)
- Sleep aids
Check the labels of any medications you are taking to see if brain fog is a potential side effect and talk to your doctor about any concerns.
Multiple Sclerosis (MS)
MS is a disease that attacks the protective layers of neural tissue, causing a wide range of problems. Symptoms may include changes in vision, inability to use the arms or legs (paralysis), and poor balance.6
Heavy Metal Toxicity
Exposure to heavy metals like lead or mercury can cause brain damage. This can lead to symptoms of fatigue, brain fog, headaches, mood changes, achiness, and more.7
Recreational drugs like marijuana, cocaine, and heroin can cause brain damage.
Chronic diseases like diabetes, kidney disease, and liver disease can cause brain damage due to problems with blood flow or inflammation.
Functional Neurological Disorder (FND)
Functional neurological disorder, previously called conversion disorder, is a condition in which psychological stress is converted into physical symptoms. These can include neurological symptoms, paralysis, seizures, blindness, or deafness. The exact cause is unknown, but it is thought to be a combination of genetics and environment.9
These are just a few examples, but there are many other causes of brain dysfunction. If you or a loved one is experiencing any problems with thinking, memory, movement, or mood, it's important to see a doctor. Brain dysfunction can be a serious condition, and the sooner it is diagnosed, the better.
Outside of the delicate brain and neural tissues, other dysfunctions can occur in the head that affects your daily life. These include:
Migraine headaches, cluster headaches, and tension headaches are all types of head pain. While its cause can be related to the brain, it's often related to nerves and blood vessels in your skull or injury/imbalance of the head and neck muscles. It can also be caused by stiffness (poor mobility) at the base of the skill where it connects to the neck or nerve involvement, such as the occipital or trigeminal nerve.
Temporomandibular (TMJ) Pain and Dysfunction
This is a disorder of the muscles and joints that connect your lower jaw to your skull. The temporomandibular joint (TMJ) sits in front of your ear. It can cause pain in or around your jaw, ear, face, neck, and head. This can affect your ability to eat, speak, and beyond.
Tooth decay, gum disease, and other dental problems can cause pain in your head and face.
This is a problem with the inner ear that can cause dizziness, vertigo, and balance problems. These can be very debilitating, disorienting, and increase the risk of falls as well. One of the most common causes of vertigo is benign paroxysmal positional vertigo (BPPV), where calcium crystals in the ear become dislodged from their normal position in the inner ear canals. This leads to mismatched signals between the brain and eyes, causing an abnormal sensation of movement and often, nausea.
This can be caused by many things including loud noise exposure, normal aging, and disease. Hearing loss can make it hard to communicate and understand others.
Tinnitus is a ringing in the ears that can be caused by many things including loud noise exposure, normal aging, and disease.
Changes in vision can be caused by many things including normal aging, disease, and injury. These changes can make it hard to see clearly for daily activities like driving and reading.
These are just a few examples of head dysfunctions that don't specifically involve the brain. These problems can be caused by a variety of factors including: injury, genetics, stress, and overall lifestyle (such as diet). If you are experiencing any type of head pain, it's important to see a doctor to rule out other causes.
Regardless of the underlying cause of your symptoms, there is a very big chance that you are dealing with functional deficits that a physical therapist can help you optimally manage. Depending on what stage of recovery you are in (and the severity of your health-related issue) you may encounter a physical therapist in the hospital, a rehab center, at home, in a clinic, or over a virtual video appointment.
Integrative Medicine for Your Brain and Daily Function
The best way to approach neurological deficits and related brain dysfunction is with an integrative medical team. This means that a team of experts works with you to ensure that you are optimizing your brain health. Examples of medical professionals you may work with include:
- Physical therapist
- Occupational therapist
- Speech and language pathologist
Your team will help you determine the underlying causes of your symptoms with functional tests, imaging, neurological screening, and more, to get you the answers you're seeking.
When working with a physical therapist, you can expect a thorough examination and personalized treatment program.
The Physical Therapy Evaluation
The first step is the evaluation. This is where your physical therapist will:
- Take a thorough medical history
- Ask you about your lifestyle and general concerns
- Perform a movement analysis
- Assess your balance and coordination
- Test your strength, flexibility, and range of motion
- And more!
This information helps your physical therapist to get an idea of what's going on to help develop an appropriate and effective treatment plan.
Physical Therapy Treatment
A physical therapist will focus on improving your strength, balance, coordination, flexibility, and endurance. They will also teach you how to properly move your body to minimize pain, prevent further injury, and improve physical function and fitness.
Most importantly, they will provide you with extensive education to understand your condition and how to proactively (and effectively) manage it. You can think of your physical therapist as your partner in problem-solving any difficulties that come your way when recovering from a head or brain-related injury. Physical therapists can also help you maximize physical function and fitness based on your diagnosis or neurological condition.
Additionally, your physical therapist can make recommendations and referrals for maximizing a healthy lifestyle. This might include finding a dietician, personal trainer, mental health provider, and beyond.
Yes! In many cases, virtual physical therapy is just as effective (if not more so) than in-person PT. Your physical therapist will be able to assess your situation and give you their professional recommendation on whether virtual or in-person care is best for you.
If you are dealing with any type of head or brain injury, such as a concussion, what type of care is best for you will ultimately depend on the severity of your injury, what symptoms you are dealing with, your access to care, and more.
For long-term or chronic deficits or less severe issues like headaches and vertigo8, virtual care has many potential benefits. You can read all about the effectiveness of virtual therapy in our full article.
