Benign paroxysmal torticollis

Benign paroxysmal torticollis is a rare, usually benign, condition classified as an episodic syndrome. It is characterized by episodes of paroxysmal head tilt and associated symptoms, some of which are shared with migraine. It is likely to be the migraine equivalent with the earliest age of onset, starting in some cases in the neonatal period but resolving typically by the age of three or four. It may evolve into other episodic syndromes, migraine, or hemiplegic migraine, and an antecedent history or family history should be sought from migraineurs. Its prevalence and under-recognition has made it difficult to study. There are emerging associations with genes implicated in other paroxysmal syndromes, including hemiplegic migraine and episodic ataxia. Treatment currently centers on supportive care and environmental modification.

Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
