Piriformis syndrome is a condition which is believed to result from nerve compression at the sciatic nerve by the piriformis muscle. [ 2][ 5] It is a specific case of deep gluteal syndrome. [ 6] The largest and most bulky nerve in the human body is the sciatic nerve. Starting at its origin it is 2 cm wide and 0.5 cm thick.
The main symptom of benign fasciculation syndrome is focal or widespread involuntary muscle activity (fasciculation). [1] The benign twitches usually have a constant location. [2] Other common symptoms are generalized fatigue or weakness, paraesthesia or numbness, and muscle cramping or spasms. [1]

Stiff-person syndrome ( SPS ), also known as stiff-man syndrome, [ 1] is a rare neurological disorder of unclear cause characterized by progressive muscular rigidity and stiffness. The stiffness primarily affects the truncal muscles and is characterised by spasms, resulting in postural deformities.
The cause is believed to be muscle tension or spasms within the affected musculature. [1] Diagnosis is based on the symptoms and possible sleep studies. [1] Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. [1] It is a relatively common cause of temporomandibular pain. [1]

A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. [ 1] They are common, with as many as 70% of people experiencing them. [ 1] They can be benign, or associated with more serious conditions. [ 1] When no cause or pathology is identified, they are diagnosed as benign ...

[1] Camptocormia, also known as bent spine syndrome (BSS), is a symptom of a multitude of diseases that is most commonly seen in the elderly. It is identified by an abnormal thoracolumbar spinal flexion, which is a forward bending of ...
The symptoms usually begin between the ages of 30 and 70 years old and appear to be more common in women than in men (2:1 ratio). The combination of upper and lower dystonia is sometimes called cranial-cervical dystonia. [2] The incidence is about one case in 20,000 people. [3]
