Apraxia has everything to do with motor planning

Monday, March 2nd, 2009

Apraxia is defined as a loss or impairment of the ability to execute complex coordinated movements without impairment of the muscles or senses.

The speech therapist said that he would never speak again after he met with severe brain injury and trauma. The area in question in the brain was called the Broca’s area which produces speech by actually stimulating the muscles that are involved in speech to contract. When damage occurs to this area, as it did with our son, the words that are said are said wrong.

The frustration level is high.

I began my research into apraxia to prove the speech therapist wrong and found my days filled with hours of repeating repetitive sounds. Was I wasting my time? And then I realized that with constant stimulation I was actually beginning to hear sounds that sounded more like the ones I was saying. I bought a recordable program and programmed into it common words that he would hear and then try to say. Sentence Shaper would become a part of our daily routine. Over and over and over. And suddenly there was improvement and no one could explain why. Even the speech therapist began organizing speech therapy activities.

The speech based program at the hospital proved fruitless. The main focus would be on his swallowing ability which I already knew was intact. We looked for different ways to help him.

Apraxia is not commonly a cognitive behavior but therapy may be one of the stepping stones involved with rehab. We were ready for anything that would come our way.

And then came Candace.

Candace was an expert on apraxia and one the best speech therapist I had ever met. Her strong desire to help and her intense methods quickly began showing their value. She began explaining to me every aspect of apraxia and knew which tools to implement. In two weeks we were already seeing amazing results.

The program that was initiated was motor based therapy. I would learn that breath support is the beginning pillar of speech based therapy and that our son was breathing for life not for speech. This would explain why he drew a breath between each word that he uttered. “Take a deep breath and hold it.” Now that seems easy for you and I but it takes motor planning which often is affected with brain injury.

We worked hard on every aspect that involved speech. We worked with bite sticks to strengthen his jaw, whistles to help with lip closure. Straws would give him the tactile cue for rounding his lips. We worked hard on separating his tongue from his jaw as they all worked as one in the beginning. He slowing began to control his breath and his speech became smoother.

Speech therapy is very important to initiate early in the brain injury rehab process. Don’t let anyone tell you differently. The brain adapts to and makes new connections early and the old saying “use it or lose it” most definitely applies.

There are many programs that are both inexpensive and and expensive that can help. Initially, “baby” words such as “ma ma”, “da da” help with sequencing and breath support. The results continue to be amazing.

All of the patients had a brain mri before they were admitted into the sub acute facility

brainmri All of the patients had a brain mri before they were admitted into the sub acute facility

Each room has it’s own story.

The brain mri is routine in determining what has happened inside the brain. I know of many patients who had a brain mri and now live in subacute on the fifth floor.

  • In one room there is the once upon a time charge nurse who bears an aneurysm in the middle of a night time shift. He is 35 years old and has worked on the floor for four years. He is rushed to the ER for a brain mri and becomes yet another patient, a neighbor to one of the patients who he once cared for. He is locked in, can’t move a muscle but retains full understanding of everything around him. His young wife is present before and after work and works diligently in the brain injury rehab process.
  • The next room houses a 21 year old man who was diagnosed with multiple sclerosis at a very young age. He has been there for years with his parents by his side. They live and breathe there and the stress of it all shows on their faces.
  • Two doors down is a retired prominent district attorney who worked his entire life to seek a perfect retirement. The day of his long awaited retirement he is involved in a rollover car accident. Here he is and has been for the last five years.
  • And then there are the ones who are dropped off and never seen again by their loved ones.

  • The 21 year old who overdosed on cocaine and survived. She was left behind in the sub-acute unit and never seen again by her parents or family. She died at the age of 42, alone.
  • There are the rich who come here. I’ve seen $100,000.00 bed’s come and go.

    And then there’s the young who say “It could never happen to me” and they too end up with a brain mri and/or brain scan.

  • John, age 19, showed up on the 5th floor after his brain images revealed a brain aneurysm. Angry as hell and after several months of brain injury rehab his mother opted to put him in a group home. He remains angry, pissed off and has severe spasticity.

    There are among the patients the ones who have diseases. There are the ones who’s muscles dance all day and others who’s muscles who don’t dance at all.

    You can walk up and down the hall and know that each room has a story of it’s own.

    # 509 has it’s own story too.

  • Bed one lays a 32 year old who was hit by a car on his bicycle in a major supermarket parking lot. This patient lay after two surgeries (one to remove a portion of his skull to aid in the removal of a “bleed” and the second to reattach the saved skull.) (In some cases the “saved” skull is retained under the skin of the abdomen until it is needed) He is loved so much by his adopted father who waits by his side for any sign of recovery.
  • Bed two was home to our son.

  • Brain MRI are routinely done after brain injury and often shows damage to the cerebellum.

    There is a main difference between where these patients remain and where others are sent after their brain mri..

    The top ten 2008 brain injury rehab centers are:

  • The Rehabilitation Center of Chicago
  • The University of Washington Medical Center
  • The Kessler Institute of Rehabilitation in New Jersey
  • Memorial Hermann-TIRR
  • The Mayo Clinic’s Physical Medicine and Rehabilitation Center
  • Craig Hospital in Denver
  • Spaulding Rehabilitation Hospital in Boston
  • Rusk Institute of the NYU Medical Center
  • Shepherd Center
  • Ohio State University Hospital
  • Researchers believe that a victim’s type and quality of care determines the outcome of their condition.

    The cerebellum is essential to the control of movement

    Monday, March 2nd, 2009

    Nerve cells of the cerebellum are arranged in an orderly manner. They function as inhibitors and organizers of the body commands initiated by the cerebral cortex, rapidly relaying messages in a manner somewhat like that of a computer.

    Our son’s brain MRI showed signs of injury to this part of his brain and no one would explain to me what exactly that would mean to his future.

    The cerebellum is essential to the control of movement of the human body in space. It acts as a reflex center for the coordination and precise maintenance of equilibrium. In other words it totally affects balance and it was quite obvious that his balance had been severely affected.

    The many days of dragging him up and down the hallway at the hospital in an attempt to get him to walk made it very difficult with this injury.

    Voluntary muscle tone as related to:

  • posture
  • balance
  • equilibrium
  • is similarly controlled by this vital part of the brain which is commonly known as the brain’s treasure. Thus all motor activity, from catching a football to playing the guitar, depends upon it.

    It lies in the posterior of the cranium, underneath the cerebral hemispheres. It is located just above the brain stem and toward the back of the brain. It is relatively well protected from trauma resulting from crushing blows compared to the frontal, temporal lobes and brain stem. It is highly vulnerable to lack of oxygen.

    This precious part of the brain is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone.

    Injury results in movements that are slow and uncoordinated. Individuals with cerebellar problems resemble person’s that may be intoxicated who tend to sway and stagger when walking.

    Damage to the cerebellum can lead to:

  • Loss of coordination of motor movement
  • Our son had the

  • Inability to judge distance and when to stop
  • The inability to perform rapid alternating movements
  • Movement tremors
  • Staggering, wide based walking
  • Tendency toward falling
  • Weak muscles
  • Slurred speech

    MRI is conducted to reveal damage to this precious part of the brain.

    There is now evidence that this precious treasure has the ability to repair itself with repeated experience.

  • The Cerebrum accounts for the superior intelligence of humans

    Monday, March 2nd, 2009

    Cerebrum is the largest part of the human brain, making up approximately 85 percent of the brain’s weight; its large surface area (cortex) and intricate development account for the superior intelligence of humans, compared with other animals.

    The cerebrum is divided by a longitudinal fissure (indentation) into right and left, miror-image hemispheres. The corpus callosum is the slab of white nerve fibers that connects these two cerebral hemispheres and transfers important information from one to the other.

    Two well-defined, fluid filled spaces call ventricles are found within each of the two hemisphere, by means of small openings called the foramen of Monro. The third ventricle leads into a fourth ventricle, locate in front of the medulla called the aqueduct of Sylvius. Cerebrospinal fluid (CSF), which circulates within these cerebral ventricles and around the spinal cord, serves to protect the internal portion of the brain from varying pressures and to transport chemical substances within the nervous system.
    CSF is formed largely in the lateral ventricles from the choroid plexus, a closely knit bed of tiny blood vessels.

    Each cerebral hemisphere consists of an outer layer of gray matter called the cerebral cortex. The cortex is composed of layers of unmyelinated cells, which in turn cover an inner mass of myelinated fibers called white matter. Myelinated fibers connect the cerebrum with other parts of the brain (protection fibers); the front of the brain to the back portion; different areas on the same side of the cerebrum (association fibers); and on side of the brain to the other side.

    Each cerebral hemisphere is divided by fissures into five lobes. Four of the lobes are named after the overlying bones of the cranium:

  • the fontal
  • the parietal
  • the temporal
  • the occipital

    The fifth lobe, the insula, is located internally and is not visible at the outside of the brain. The frontal and parietal lobes are separated centrally by the fissure of Rolando; the parieto-occipital fissure separates the parietal lobe from the occipital lobe; and the temporal lobe lies below the fissure of Sylvius.

  • Brain anatomy is the most fascinating and most important of all biological systems

    Monday, March 2nd, 2009

    To the Egyptians, the heart was the essence of life. Brain anatomy was unimportant. The brain was considered a minor, unimportant organ. They discarded it during the embalming process even as they preserved other organs for mummification. Skulls with evidence of healing have been found at many sites, suggesting that the subjects of operations survived.It’s funny how I never really thought seriously about the brain as a physical organ that regulates the body, like the heart, lungs, or kidneys. For most of my adult life, I’d never really considered the role it plays in walking, sitting, running, and jumping.

    Clearly brain anatomy shows the brain has two sides:

  • right hemisphere that controls the left side of the body
  • left hemisphere that controls the right side.Each hemisphere has four lobes. The cerebral cortex in humans is divided into two hemispheres, the left and right cortex. In most humans the left hemisphere (which controls the right side of the body) is the language center where Brocas area is located. It is also the dominant hemisphere. The left cortex will tend to be logical, analytical, linguistic and sequential in its information processing, while the right cortex will usually be intuitive, holistic, picture-oriented and simultaneous in its information processing.When there is trauma such as a aneurysm or a stroke these areas are always affected.
  • Research has shown in brain anatomy that most people favor one hemisphere over the other, with the dominant hemisphere being more electrically active and the non-dominant hemisphere relatively more electrically silent, when a person is being tested or asked to solve problems or respond to information. The two cortical hemispheres are linked by a bundle of nerve fibers. In theory these two structures should unite the function of the two hemispheres. In practice they act more like a wall separating them.

    From a neurological perspective, the cerebral basis for a well-functioning mind would be the effective, complementary, simultaneous integrated function of both cortical hemispheres, with neither hemisphere being permanently dominant. This in turn would require nerve fibers to optimize information flow between the two hemispheres. Research has shown Piracetam to facilitate such inter-cerebral information transfer-indeed, it’s part of the definition of a “nootropic drug.”

    Brain anatomy studies the cerebellum

    that controls our daily functions. Our son had stayed alive because there had been no damage to his brain stem, the section in the back of the head on top of the spinal cord that regulates breathing, heartbeat and other involuntary functions necessary for life. It is apparent that our son has most of his injury in the frontal lobes, the area of the brain that governs speech, memory, movement and personality. The frontal lobes are the parts of the brain, essentially, that makes us who we are. Depending on what parts of the brain has been affected, stroke victims experience a variety of neurological deficits.

    Brain injury rehab

    is crucial to the stroke or brain injury patient’s recovery. Physical therapists and speech therapists help patients “relearn” their lost functions and devise ways to cope with the loss of those they cannot regain.
