Hand spasms, also known as carpopedal spasms, are involuntary contractions or twitching of the muscles in the hand or fingers. There are several different synonyms that can be used to describe this condition, including hand tremors, hand shakes, hand convulsions, and hand twitches. Additionally, spasms can occur in other parts of the body, and synonyms for these types of spasms include muscle spasms, involuntary muscle contractions, and jerking movements. While hand spasms can be harmless, they can also be a symptom of an underlying medical condition, such as a neurological disorder or a mineral deficiency. Treatment options depend on the severity and cause of the spasms, and may include medication, physical therapy, or lifestyle changes.
