Movement Disorders

Dystonia

    Occasionally referred to as torticollis, which is a type of dystonia, dystonia is a type of neurological movement disorder characterized by involuntary muscle contractions, or spasms.  As far as movement disorders, dystonia is in the top three, with Parkinson's disease and essential tremors.  Dystonia is not gender or race specific.  Frequently, certain parts of the body will be forced into abnormal, painful, movements or postures. Dystonia varies by affect and may involve any part of the body including the arms and legs, trunk, neck, eyelids, (blepharospasm), face, or vocal cords, (as a tic).

    While dystonia is not fatal, it is a chronic disorder and prognosis is difficult to predict.  Impairment caused by dystonia is due to muscle contracture, which can interfere with normal function. Although cognition,  and the senses, including vision and hearing are technically normal, they are routinely affected both neurologically with progression of the disorder, as well as due to the inability to prevent movement, allowing continual overcorrection to be made with the eyes.  With progression of the disorder, twisted postures associated with the muscle spasms affecting limbs and trunk, bizarre walking with bending and twisting of the torso, rapid and sometimes rhythmic jerking movements, and progression of symptoms leading eventually to sustained fixed postural deformities are not uncommon.  Needless to say, this is associated with significant pain.

What is Blepharospasm?

    Blepharospasm is an abnormal, involuntary blinking or spasm of the eyelids.

Orthostatic Tremor

    Primary orthostatic tremor is a rare movement disorder characterized by high frequency tremors of the legs when standing, (13-18 Hz) causing severe contractions of the muscles of both legs simultaneously. The tremor worsens the longer the patient tries to stand without movement.  This disorder is very often misdiagnosed as other neurological problems such as Parkinson's, MS etc.  The tremor disappears partially or completely when an affected person is walking or sitting. Individuals with primary orthostatic tremor experience feelings of unsteadiness or imbalance. 

Essential Tremor

    Essential tremor is the most common neurologic movement disorder.  Essential tremor is a chronic condition characterized by involuntary, rhythmic tremor of a body part, typically the hands and arms.  Hand tremor is the most common form of essential tremor. It  involves agonist and antagonist muscles and is usually, but not always, bilateral.  Essential tremor may progress to involve the head, followed by the voice, tongue, legs, or trunk. The movements associated with head tremor usually occur in a horizontal "no-no" pattern.  Head tremors may also occur in a vertical "yes-yes" pattern. 

Research Based Non-surgical Treatment for Dystonia

    Recent research by Frederick Carrick, DC, PhD, DACNB proved the tremendous effect chiropractic neurologists can have on cervical dystonia when managed in accordance to brain based neurology. The study included 111 subjects in a clinical setting. Patients were treated as determined by physiologic blind spot mapping of the eyes and other neurologic findings. Each subject was treated an average of six times. Follow-ups two months later rated 67.6% had at least a 50% improvement in movement, 55.2% had at least a 50% reduction in tremors, 57.7% had at least a 50% decrease in muscle spasticity and 77.5% had at least a 50% decrease in pain. These results are outstanding and provide hope for dystonic patients looking for non-surgical treatment options.

Botulism Toxin Injections for Dystonia

    It is most unfortunate for most, that it is typically the first order of treatment to render botulism toxin injections for treatment of dystonia.  These injections, which are only temporary at best, should obviously be reserved for secondary treatment following failed more conservative measures, or, in conjunction with conservative measures.  Botulism toxin is not curative.  If it works at all, it is temporary and must be performed continually with expression of symptomatology.
