Action Tremor
As indicated, action tremor takes place only when an affected body part is moving to change position intentionally. Action tremor is subdivided into three types: cerebellar lesion, rubral tremor, and psychogenic tremor. Cerebellar lesions and rubral tremors are discussed in the paragraphs below (Grimaldi & Manto, 2013).
Cerebellar lesion. A cerebellar lesion is a tremor related to cerebellar disorders. It happens after a patient suffers a stroke that causes cerebellum damage. The damage to the cerebellum impairs muscle coordination and deactivates the brain’s control of a body part’s movement. It is mainly composed of low frequency oscillations. This can lead to an inability to coordinate balance while walking, and trouble stabilizing

Dystonic tremor is a type of tremor that can affect any individual under any age. This disease takes place in conjunction with a neurological disorder called dystonia. When incorrect message from the brain affects some muscles, it results in abnormal movements of body parts. Its amplitude and frequency are unknown.
Orthostatic tremor. Orthostatic tremor is described by periodic muscle contractions that take place in the legs and trunk instantly after standing. Its amplitude and frequency are unknown.
Differences Between Essential Tremor and Parkinson’s Disease
Essential tremor, as described earlier, is not only considered the most widespread of abnormal neurological diseases, but also the most widespread among all other tremor diseases. Parkinson’s disease is rest tremor that is a progressive neurodegenerative disorder, originally described by James Parkinson in 1817. According to the Mayo Clinic, many people confused ET and PD, though they differ in many aspects:
• Genetic. Many cases of ET occur in family while PD never transfer in family and is caused by the damage of neurons in the brain.
• Associated conditions. ET causes other health problems, but PD is associated with a stooped posture, slow movement, and a shuffling gait. However, people with ET may sometimes develop other neurological signs and symptoms, such as an unsteady gait called ataxia (Mansur et al.,
The most common sign of Parkinson’s is shaking of a patients body, most commonly the hands. With time these symptoms worsen and can become as serious as having difficulty swallowing in the later stages of the disease (WebMD, 2014). The symptoms that occur in between these two stages vary greatly. A symptom that develops shortly after the beginning stage is bradykinesia, slow movement (Mayo Clinic, 2014). This affects a person’s ability to walk or even the capability to get out of bed. Another symptom such as muscle rigidity occurs in numerous patients. This muscle stiffness can arise in any part of a victim’s body. This decreases a person’s area of movement because of the immense amount irritation that takes place.
Parkinson disease (PD), also referred to as Parkinson’s disease and paralysis agitans, is a progressive neurodegenerative disease that is the third most common neurologic disorder of older adults. It is a debilitating disease affecting motor ability and is characterized by four cardinal symptoms: tremor rigidity, bradykinesia or kinesis (slow movement/no movement), and postural instability. Most people have primary, or idiopathic, disease. A few patients have secondary parkinsonian symptoms from conditions such as brain tumors and certain anti-psychotic drugs.
Parkinson's disease is a progressive degenerative disorder of the central nervous system that affects the motor system. It is marked by tremor at rest, muscular rigidity, postural instability, and slow, imprecise movement. The most obvious symptoms are movement related, which include; shaking, rigidity, slowness of movement, difficult with walking, balance, and gait. Other motor symptoms include: posture disturbances, such as a decrease in arm swing, a forward flexed posture, and the use of small steps when walking. Speech and swallowing disturbances are also common motor problems that can appear as well to a patient with Parkinson's disease. Young adults rarely experience Parkinson's disease because it is more common to affect
Parkinson’s disease (PD) is the second most common neurodegenerative disease. Two other names for PD are shaking palsy and Paralysis agitans. Parkinson’s disease is initiated when the cells in the brain that produce dopamine die over time. Dopamine is a brain chemical used by nerve cells that helps to control the body 's muscle movement. Without those brain cells and the dopamine they produce, it becomes increasingly more difficult for the cells that control movement to send messages to the muscles; affecting the body’s movement. As time goes on the damage worsens. There is not a known cause as to why these brain cells die, although there are a few theories ("MedlinePlus Medical Encyclopedia:
(Hoehn). Interestingly, when the symptoms first appear there has already been of loss of 60% to 80% of the neurotransmitter dopamine. (Heyn). Further, Parkinson’s disease presents uniquely in each patient in the severity and frequency of symptoms, the rate of progression, and the stages experienced. (WEBMD). In the first stage of the disease, the symptoms although mild still inconvenience the patient during routine daily activities. At this stage, most symptoms are unilateral and include tremor, pill rolling (when the thumb and index finger are bought together there is an uncontrolled circular movement), ataxia (condition of being without coordination), hypomimia (condition of deficient facial expression), dyskinesia (condition of difficulty in performing voluntary movements), and stooped posture. (WEBMD). Next, the disease progresses to Stage 2 the symptoms become bilateral while the initial symptoms increase in severity and include bradyarthria (condition of slowed speech), hypophonia (condition of deficient sound), monotone voice, dysphagia, diaphoresis, dermatitis, and polyuria. (WEBMD). During Stage 3 of the disease the list of symptoms continues to grow and the existing symptoms continue to worsen, the new symptoms include atasia
Parkinson's disease is the second most common neurodegenerative disorder and the most common movement disorder. Characteristics of Parkinson’s disease are progressive loss of muscle control, which leads to trembling of the limbs and head while at rest, stiffness, slowness, and impaired balance. As symptoms worsen, it may become difficult to walk, talk, and complete simple
Bradykinesia is a symptom of Parkinson’s where movement is slowed, making it very difficult for the person to complete normal tasks depending on how severe it is. Tremors are an infamous symptom of Parkinson that causes a person to shake when they rest. Multiple parts of the body can be affected by tremors such as the jaw, hands, lower lip and leg, but hands are the most common place for tremors. Micrographia is a symptom that causes writing to be small and closely packed. Other symptoms of Parkinson’s is tight or stiff muscles in the body as well as problems with balance that causes patients to fall. Patients also lack facial expression because of the “rigid” muscles. The voices of those affected tend to be very soft and indistinct. There are many other symptoms of Parkinson’s that are not related to movement. Patients are known to have mood changes which can be anything from depression to anxiety. Many that have the disease experience changes in the brain that can affect thinking ability. Cognitive problems that occur consist of trouble focusing, memory loss, and dementia. Parkinson’s also causes a large amount of sleep disorders. Patients can have insomnia, daytime sleepiness, and restless leg syndrome. Constipation is also a symptom due to slowed body movement digestion takes longer. Some also have urinary problems such as frequency or urgency. Automatic
Parkinson’s disease (PD), a degenerative nervous system disorder, is more common every day, yet it is still a mystery on what causes it. More than a million Americans have been diagnosed with PD and every year there are 60,000 new cases. Affecting older people, it is the second most common disorder and the condition is expected to increase as the aging population increases. PD essentially is the loss of dopamine-producing neurons. The increase in research has led to a wide range of possibilities to the causes involving both genetic and environmental factors. There are two different types of symptoms: motor and non-motor.
There are many symptoms when it comes to having Parkinson’s disease. The first of the types are motor symptoms. The most common, but major symptom of PD is dyskinesias or tremors. Tremors is when you have little, uncontrollable movement in you body, such as in your arms, in your legs, and even in your face. Also medicines such as MAO-B inhibitors, COMT inhibitors, and others can cause dyskinesias to get worse and put you in a not so good position. (Lazarus Motor)
Parkinson disease (PD) is a progressive neurodegenerative disorder characterized mainly by physical and psychological disabilities. This disorder was named after James Parkinson, an English physician who first described it as shaking palsy in 1817 (Goetz, Factr, and Weiner, 2002). Jean- Martin Charcot, who was a French neurologist, then progressed and further refined the description of the disease and identified other clinical features of PD (Goetz, Factr, and Weiner, 2002). PD involves the loss of cells that produce the neurotransmitter dopamine in a part of the brain stem called the substansia nigra, which results in several signs and symptoms (Byrd, Marks, and Starr, 2000). It is manifested clinically by tremor,
Hand tremor affects millions of people worldwide. Tremor is defined as an unintended, rhythmic muscle movement. According to Plumb and Bain (2006), tremor is one of the most spread disease among the population of patients diagnosed with movement illnesses (p. 75). This is one of the reasons why medical scientists take tremor so seriously. Tremor can affect different parts of the body, including hands, legs, head, or face. In the worst situations, tremor can affect voice and swallowing, but most tremor cases occur in the hands.
Parkinson’s disease is one of the syndromes studied in functional neurosurgery. Parkinson’s disease has a very slow progressing rate which usually causes stiffness, slow movement, and balance and coordination impairment. This disease is diagnosed in approximately 60,000 Americans each year. Chemical imbalance likely causes Parkinson’s disease. Dystonia is a disease in which the body is affected in the way it moves. It causes your muscles to contract, which makes them move involuntarily, or get stuck in an abnormal position (Fraser). This disease can either affect the whole body or just certain parts. This can cause the body to be in pain. The well known disorder of OCD (Obsessive Compulsive Disorder) is diagnosed in two to three percent of the world’s population. OCD is defined by consistent and persistent thoughts. In regular thought and behavior, people’s brains know when to avoid a behavior and also approach. Essential tremor is a functional neurosurgery disorder. Essential tremor (ET) is a slowly progressive neurological disorder whose most recognizable feature is a tremor of the arms that is apparent during voluntary movements such as eating and writing (Hanrahan). This tremor is referred as “kinetic tremor” often. The essential tremor occurs in the head, neck, jaw, voice, and many other parts of the body as
Stage Two: The symptoms begin to get worse. Tremors can occur in the hand and fingers.
The disease is more common in men 65 or older . Possible reasons for this can be because men are more likely to be exposed to environmental toxins. The symptoms of PD are tremors(shaking),bradykinesia(slow movement),muscle stiffness,
The most common presenting symptoms for PD are tremors at rest of the upper extremities, bradykinesia, rigidity and postural instability.
