ABSTRACT– This article reviews the complete resolution of a case of benign essential tremor, in a patient treated with acupuncture, who previously had limited response to drug therapy. Three treatments were given over a three-week period. The patient’s tremor of the head and upper extremities resolved 100%, and she has remained asymptomatic to date (5 months after the last treatment).
In April, 1989, a 38-year-old white female, presented with the chief complaint of intolerable shaking of her head for over one year. From 1987 until then, she was treated for a variety of routine conditions at the practice. She had been diagnosed as having benign essential tremor for many years. Her mother, also a patient of the practice, reported that the patient suffered tremor of the upper extremities since approximately age 2~3, being nicknamed “shaky bones” by her peers. The main medications were propanolol and diazepam, which only provided modest reduction in the intensity of the tremor.
Her condition had been extensively studied at several medical centers, where she was repeatedly told that “she had to learn to live with the tremor, hopefully obtaining some relief by taking prescribed medications”.
The patient’s family history was significant for alcoholism in both parents, a disease which had also afflicted her. She became a heavy drinker between the ages of 21 and 25, and then again between 35 and 37. Other significant medical history included asthma in childhood, excision of an ovarian cyst in 1970, and a twin pregnancy delivery in 1982. The patient is married and owns a successful business.
Marked tremor of the upper extremities (1,2,3), both postural and during voluntary activity, was observed since her first visit in 1987. Around February, 1988, the patient began to notice tremor of her head, which had not been present previously. In May, 1988, she was hospitalized for alcohol detoxification. Soon after discharge, she complained of worsening of her head tremor. She continued sober but increasingly tremulous u ntil April, 1989, when she returned, requesting acupuncture to help her with her head tremor, which by then had become intolerable.
The patient’s constitution was determined to be JUE YIN- Wood, on the East position, according to Dr. Yves Requena’s classification (4). Treatment was then organized following Dr. Maurice Mussat’s “Energy of Living Systems” theory (5,6), specifically the use of triangular equilibration.
Her first treatment, on April 14, 1989, consisted of a JUE YIN triangular equilibration in evolution, using points along the JUE YIN (Lived Master of the Heart), ABSOLUTE YIN (Conception Vessel), and YANG MING (Large Intestine/Stomach).
On her follow-up visit, one week later, she reported great improvement of her head tremor, and mentioned the onset of an unusual craving for sweets. She was then treated with a TAE YIN simple triangular equilibration, with points on TAE YIN (Spleen/ Lung), YANG MING and ABSOLUTE YANG (Governor Vessel).
On her third visit, on April 27, she reported further improvement of her head tremor, and an unexpected complete resolution of her upper extremities tremor. It was then decided to conclude her treatment series with a SHAO YANG simple triangular equilibration (Triple Heater/Gall Bladder), SHAO YIN (Kidney/Hear[), and ABSOLUTE YANG. She was instructed to return 3 weeks later for reassessment.
She did not return until 2 months later, on June 27, when she reported complete resolution of both her upper extremities and head tremor. She was still taking di-azepam, 5 mg twice a day, but had stopped taking propanelei. She was advised to taper off the diazepam, and return for another series of acupuncture treatments, should symptoms recur.
She did not return until 3 months later, on September 28, when she brought in her mother for treatment. At the time, the patient reported no recurrence of her symptoms, being free of tremor for 5 months to date, and without taking any medications. A physical examination, including neurological evaluation, was normal.
Tremors may be physiologic or a symptom of neurologic disease, such as tumors, trauma, infections, demyelinating disease, Parkinson’s disease, peripheral neuropathy, and essential tremor (7). Benign essential tremor (called familial or hereditary tremor when there is a positive family history) is thought to be inherited as a Mendelian autosomal dominant trait. No neuropathological lesion has been recognized in post mortem examinations, its neurochemistry is unknown, and its pathophysiology is obscure (8). It may appear at almost any time, often in early adult life, but it may begin in childhood (9}. It is characterized by coarse, rhythmic and symmetric tremor, persisting throughout the range of motion of voluntary activity, increasing in amplitude as the limb approaches an object (finger-to-nose test), or in handling or bringing food or liquid to the mouth.
The frequency of the tremor varies between 6 and 12 Hz, most commonly recording 6-8 Hz (10). The tremor amplitude diminishes with rest and the use of alcohol, and is exacerbated by emotional and physical stress. Tremor increases m amplitude with age, and may eventually interfere with fine movements.
Propanolol (in doses of 40-240 mg/day) and other beta-antagonists which pass the blood-brain barrier and therefore have central and peripheral actions, have been used with varying responses, but no definitive cure (11,12). More recently, primidone has been reported to be as effective as propanolol in treating this condition (13). Alcohol, although the most effective agent, is not recommended. Chronic alcoholism in patients with essential tremor is often a consequence of their attempts to control the symptoms by drinking (14).
The treatment of tremors with acupuncture has 1cng been documented in the classical Chinese medical texts, and continued to be reported in the European and American literature (15), as “problems related to Wind of External and Internal origin”.
For wider clinical applications, the therapeutic response of benign essential tremor to acupuncture needs to be studied in a significant sample of patients with this same condition. However, the complexity of medical acupuncture is such that treatment protocols may be inadequate to incorporate the necessary data into a useful diagnostic and therapeutic formulation (16). The patient’s own diagram of constitutional characteristics, past history, family history, and associated symptoms, eventually determine the most appropriate therapeutic intervention in each case.
With this individualized approach, other functional movement disorders may also be considered as potentially responsive to Medical Acupuncture. Concomitantly, further observations of the effect of acupuncture on tremors may lead to unexpected insights into intrinsic aspects of the motor system.
