spasm


spasm,

involuntary rigid muscle contraction, often persistent and often accompanied by pain. It usually has some underlying physical cause such as disease, strain, or injury to the muscle or nearby tissues, impairment of circulation, or a disturbance of body chemistry. The spasm may be confined to one group of muscles or it may be severe and fairly generalized, as in convulsionsconvulsion,
sudden, violent, involuntary contraction of the muscles of the body, often accompanied by loss of consciousness. It is not known what causes the abnormal impulses from the brain that result in convulsive seizures, since the disturbance may arise in normal brain

. Painless localized spasms are called tics. These purposeless movements, usually of some part of the face, may begin as purposeful movement in response to some stimulus but eventually are carried out automatically, apparently without reason. They may disappear spontaneously after a time, or may require the elimination of some physical or psychic cause.

Spasm

 

an involuntary tonic contraction (cramp) of a muscle or group of muscles. Spasms may affect striated skeletal muscles (for example, with certain paralyses) or smooth muscles. Subject to spasms are the smooth muscles of the vascular wall (for instance, during angina pectoris), the bronchi, the esophagus (cardiospasm), and the intestine. Skeletal-muscle spasms make movement difficult, and smooth-muscle spasms disrupt various functions of organs.


Spasm

 

a sudden involuntary muscular contraction marked by extreme tension. Two types of spasms are distinguished: tonic and clonic. In tonic spasm, the tension persists for a long time, and in clonic spasm, there are synchronous jerking muscular contractions, which may be diffuse or limited. Spasms of different muscle groups are designated by specific terms, for example, trismus (spasm of the masticatory muscles) and blepharospasm (spasm of the ring muscle of the eye). Clonic spasms of the entire body are sometimes called convulsions.

Spasm may arise spontaneously or as a reaction to external influences, for example, spasm of the gastrocnemius muscles after chilling in water. It may also result from internal influences, for example, tension of the abdominal muscles in peritonitis. Spasm may be a manifestation of epilepsy, eclampsia, spasmophilia, inflammation, brain tumor and trauma, and many other disorders. In addition to spasm of striated muscles, there is spasm of smooth muscles, for example, cardiospasm and pylorospasm. In children, spasm is most common at a very early age, owing to the structure and functioning of the brain at this stage of life; it results from infection, poisoning, trauma, and various psychogenic factors.

Spasm is treated by caring for the underlying disorder and by administering such anticonvulsants as phenobarbital, primidone, and diphenylhydantoin. The affected person should get sufficient sleep and should abstain from alcohol.

spasm


spasm

 [spazm] 1. a sudden involuntary contraction of a muscle or group of muscles.2. a sudden, transitory constriction of a passage, canal, or orifice; spasms usually occur when the nerves supplying muscles are irritated, and are often accompanied by pain. A vasospasm" >vasospasm is a rare type that occurs in a blood vessel. Spasms vary from mild twitches to severe convulsions" >convulsions and may be the symptoms of any number of disorders. Usually, they will cease when the cause is corrected, but sometimes the only treatment is to suppress the symptoms, as in epilepsy.
Clonic Spasms. These are spasms in which contraction and relaxation of the muscle alternate; this is the most common type of spasm and usually is not severe. A typical clonic spasm is the hiccup" >hiccup. Hiccups usually occur when the diaphragm is irritated, as by indigestion, although occasionally they may result from a serious condition such as a brain tumor; they generally disappear by themselves or after a drink of water.

Spasms may be repetitive twitching motions, some of which are called tics. Tics often accompany other types of spasm, as in such diseases as cerebral palsy and sydenham's chorea, and may also be seen in neuralgia. In tic douloureux the nerves of the face are involved.
Habit spasms are a type of repetitive twitching movements that seem purposeless or without a cause; they include twitching of the face, blinking of the eyes, and grimacing. The movements are rapid and always repeated in the same way, unlike the spasms associated with chorea. The motions are carried out automatically in response to a stimulus that once may have existed but no longer does.
In a convulsive spasm the entire body is jerked by sudden violent movements that may involve almost all the muscles. These spasms may last from a fraction of a second to several seconds, or even minutes. (See also convulsion.)
Tonic Spasms. If the contraction of a spasm is sustained or continuing, it is called a tonic or tetanic spasm. These are generally severe because they are caused by diseases that affect the central nervous system or brain, such as tetanus, rabies, and cerebral palsy. Severe tonic spasms can be fatal if not treated promptly; continued spasms can bring on exhaustion or asphyxiation. The treatment varies with the cause; if the disease is caused by a microorganism in the system, as in tetanus, antiserum must be administered immediately. Antibiotics are also used to help curb infection. In many cases tranquilizers, sedatives, and narcotics must be administered to help ease the spasms.
bronchial spasm spasmodic contraction of the muscular coat of the smaller divisions of the bronchi, as occurs in asthma; called also bronchospasm.clonic spasm a spasm consisting of clonic contractions; see also clonus.infantile s's (infantile massive s's) (jackknife s's) a syndrome of severe myoclonus appearing in the first 18 months of life, and associated with general cerebral deterioration; it is marked by severe flexion spasms of the head, neck, and trunk and extension of the arms and legs. Called also jackknife seizures.nodding spasm clonic spasm of the sternomastoid muscles, causing a nodding motion of the head.saltatory spasm clonic spasms of the muscles of the lower limbs, producing a peculiar jumping or springing action.tetanic spasm (tonic spasm) tetanus" >physiological tetanus.

Patient discussion about spasm

Q. DO YOU KNOW HOW TO STOP YOUR PANCREAS FROM SPASMS, I HAVE A HARD TIME WHEN IT SEEMS MY PANCREAS IS ACTING UP IT HURTS SO BAD AND MY LIPIDS ARE HIGH HOW DO I GET RID OF THE PAIN OR CONTROLL IT.A. the Pancreas does not have sensory nerves in it. this is the reason why pancreas cancer is the most deadly- you don't realize it's there until it's much too late. so this pain you describe does not ad up to be from the Pancreas.
i think this is a very good reason to see a Doctor.

Q. I ask a client's Dr. to script flexaril for a lower back spasm and he made it for a drug called zanaflex? I am unfamiliar with zanaflex, what is the difference between it and flexaril 25mg? Benefits? Risks? I got him to order the air mattress and extended bed because client is 6'3" and is already bedridden on my 1st day..try to beat the skin breakdown, already stage I decubitis ulcers. I tried to talk the client into slideboard and lift away arm wheelchair...noway..he wants to walk bent with a rolling walker. He already had a lift chair delivered, so he just goes from bed to lift chair. He refuses to let me bathe him. He can't see, and he has me check his draw up on insulin to make sure it's right. He sends the P.T. man right back out the door after he signs the sheet. Difficult pt.!A. Flexeril and Zanaflex are different drugs but are both muscle relaxants. There are hardly any differences between the two, clinically wise. If the doctor thought one is better than the other for your client I would suggest you take his advice and use the one he gave you.
