Over-sensitivity of motor nerves to stimuli; particularly affects face, hands, and feet. Caused by reduction in the level of ionised calcium in the bloodstream and can accompany severe rickets
Nervous condition characterized by sharp, painful, periodic muscle contractions, particularly those of the extremities.
Hyperexcitability of nerves and muscles resulting from low serum calcium levels; a syndrome characterized by intermittent tonic spasms of the extremities, cramps, and convulsions.
A condition that results from a low level of calcium in the blood and is characterized by tingling in the hands, feet, and around the mouth and by painful spasm of the muscles of the hands and feet.
A condition characterized by sharp bending (flexion) of the wrist and ankle joints, muscle twitching, cramps, and convulsions. Inadequate calcium in the blood causes irritability of the nerves and muscles so that they respond to a stimulus with greater sensitivity and force than is normal.
Spasms of the muscles in the feet and hands, caused by a reduction in the level of calcium in the blood or by lack of carbon dioxide.
A condition, often due to body calcium imbalances or a vitamin D deficiency, which is marked by muscular spasms and tingling sensations.
A disorder characterized by intermittent tonic muscular contractions accompanied by fibrillary tremors, paresthesia, and muscle pain.
Spasms, cramps, or twitching in the muscles, especially of the hands and feet, sometimes with stridor (noisy breathing) as well. Tetany generally results from too little calcium in the body (hypocalcemia), often linked with lack of vitamin D. In newborns, tetany can result from imbalance in the parathyroid hormone or imbalance in formula and is more common in low-birth-weight babies.
Disorder, usually caused by a disorder of calcium metabolism, associated with hypoparathyroidism, vitamin D deficiency, or alkalosis and characterized by muscular twitching, cramps, and convulsions.
Painful intermittent muscle spasms frequently associated with calcium imbalance.
Muscle cramps, spasms, and sometimes convulsions associated with low blood levels of calcium.
An abnormal condition characterized by spasms of the arm and leg muscles. Tetany, a potentially life-threatening condition, is caused by a severe lowering in the calcium level, which may be due to a lack of vitamin D, hypoparathyroidism (underactivity of the parathyroid glands), alkalosis (an abnormal state caused by excessive vomiting, hyperventilation, exposure to high altitudes), or the ingestion of alkaline salts. Tetany can also cause spasms of the larynx, resulting in breathing difficulties. Acute tetany may lead to respiratory obstruction requiring a tracheostomy.
Spasm and twitching of the muscles, particularly those of the face, hands, and feet. Tetany is caused by a reduction in the blood calcium level, which may be due to underactive parathyroid glands, rickets, or alkalosis.
A condition characterized by spasm of muscle, usually caused by a fall in blood calcium levels. This results in hyperexcitability of muscles which may go into spasm at the slightest stimulus. This is well demonstrated in two of the classical signs of the disease: Chvostek’s sign, in which the muscles of the face contract when the cheek is tapped over the facial nerve as it emerges on the cheek; and Erb’s sign, in which muscles go into spasm in response to an electrical stimulus which normally causes only a brief contraction of the muscle. Tetany can occur in premature newborn babies who may have a low level of calcium, and in children as a result of rickets, it also occurs after excessive vomiting, or certain forms of nephritis. It may also be due to lack of the active principle of the parathyroid glands. Over-breathing may also cause it. Treatment consists of the administration of calcium salts, and in severe cases this is done by giving calcium gluconate intravenously or intramuscularly. High doses of vitamin D are also required.
Intermittent tonic muscular spasms that typically involve the arms or legs.
Muscle rigidity is a medical condition that entails the involuntary contraction of the skeletal muscles, leading to a sustained increase in muscle tone. This phenomenon is characterized by the inability of the affected muscles to relax, which can lead to a range of complications, including pain, impaired movement, and deformities. The rigidity can manifest in various forms, including stiffness, spasticity, and dystonia, depending on the underlying cause and the muscles involved. The condition can be caused by various factors, such as neurological disorders, infections, injuries, or medications, and can affect individuals of all ages.
A neurological disorder distinguished by muscular contractions, convulsions affecting the limbs, and a sensation of numbness in the extremities.
Muscle spasms and involuntary movements, predominantly occurring in the hands and feet, although facial, laryngeal (voice box), and spinal muscles may also be involved. These spasms result from a biochemical disruption and are initially without pain. If the condition endures, the spasms typically intensify in their discomfort.
Failure to address the underlying cause could lead to muscle injury. The primary trigger is typically hypocalcemia, characterized by low levels of calcium in the bloodstream. Other contributing factors encompass hypokalemia (insufficient potassium levels), rapid breathing during a panic attack, or, in rarer instances, hypoparathyroidism which involves reduced function of the parathyroid glands.
A condition marked by periodic, painful muscle contractions.
