Tremors :
Tremor, as a function refers to an involuntary, rhythmic contraction of the muscles causing shaking or trembling movement that most often affects the hands, arms, or legs. Tremors can occur both at rest and during movement and may be variable in intensity. There are different factors that cause tremors like Parkinson's disease, multiple sclerosis, and essential tremor, but others associated with anxiety, fatigue, or a particular drug used by the patient. The kind of tremor its frequency, and body parts involved can be of help in the diagnosis of the underlying cause. It depends on the nature of the case on how the treatment might be done with medications (such as beta-blockers or anti-seizure drugs), physical therapy, or changing lifestyle. Some patients with severe cases can opt for surgical options that can improve the daily functioning.
