It interferes with activities such as writing or playing a musical instrument by causing involuntary muscular contractions. The condition is sometimes "task-specific", meaning that it is generally apparent during only certain activities. Focal hand dystonia is neurological in origin and is not due to normal fatigue.
Torsion dystonia, also known as dystonia musculorum deformans, is a disease characterized by painful muscle contractions resulting in uncontrollable distortions. This specific type of dystonia is frequently found in children, with symptoms starting around the ages of 11 or 12.
A hiccup is a spasmodic contraction of the diaphragm, which pulls air against the closed folds of the larynx. The phrenic nerve must be identified during thoracic surgery and preserved. To confirm the identity of the phrenic nerve, a doctor may gently manipulate it to elicit a dartle (diaphragmatic startle) response. [7]
A spasm is a sudden involuntary contraction of a muscle, [1] a group of muscles, or a hollow organ, such as the bladder. A spasmodic muscle contraction may be caused by many medical conditions, including dystonia. Most commonly, it is a muscle cramp which is accompanied by a sudden burst of pain. A muscle cramp is usually harmless and ceases ...
Spasmodic torticollis is a form of focal dystonia, a neuromuscular disorder that consists of sustained muscle contractions causing repetitive and twisting movements and abnormal postures in a single body region. [9] There are two main ways to categorize spasmodic torticollis: age of onset, and cause.
The diagnosis of focal dystonia is highly dependent on the history of the patient, as physical exam is typically normal, and ruling out other causes of movement disorder. [10] [11] The main types of are blepharospasm, oromandibular dystonia, spasmodic dysphonia, spasmodic torticollis, and limb dystonia, all affecting a different region of the ...
A simple treatment involves increasing the partial pressure of CO 2 and inhibiting diaphragm activity by holding one's breath or rebreathing into a paper bag. [30] Other potential remedies suggested by NHS Choices include pulling the knees up to the chest and leaning forward, sipping ice-cold water and swallowing some granulated sugar.
Dystonia is a response to simultaneous contraction of agonist and antagonist muscles seen as twisting and contorting that affect posture and stance. Other symptoms can include tremors and muscle spasms due to various interactions of muscle, contractions and movement. [4] Dystonia can be either primary or secondary with the latter being more common.
