Benign fasciculation syndrome (BFS) is characterized by fasciculation (twitching) of voluntary muscles in the body. [1] The twitching can occur in any voluntary muscle group but is most common in the eyelids, arms, hands, fingers, legs, and feet. The tongue can also be affected. The twitching may be occasional to continuous. [2]
Myoclonus is a brief, involuntary, irregular (lacking rhythm) twitching of a muscle, a joint, or a group of muscles, different from clonus, which is rhythmic or regular. Myoclonus (myo-"muscle", clonus "spasm") describes a medical sign and, generally, is not a diagnosis of a disease.
A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, ... Small twitches of the upper or lower eyelid, for example, are ...
Flail arm syndrome is characterized by lower motor neuron damage affecting the arm muscles, typically starting with the upper arms symmetrically and progressing downwards to the hands. [2] Flail leg syndrome is characterized by lower motor neuron damage leading to asymmetrical weakness and wasting in the legs starting around the feet. [2]
Essential tremor (ET), also called benign tremor, familial tremor, and idiopathic tremor, is a medical condition characterized by involuntary rhythmic contractions and relaxations (oscillations or twitching movements) of certain muscle groups in one or more body parts of unknown cause. [6]
“The proportion of slow-twitch to fast-twitch muscle fibers in a particular muscle varies depending on the function of the muscle and the type of training in which an individual participates.
A tremor is an involuntary, [1] somewhat rhythmic muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs. Most tremors occur in the hands.
The twitching of the right eye could be seen as a heightened sensitivity to energies and a potential awakening of one's intuition. Some believe that it signifies an opening of the third eye.
