Spastic constipation is a form of constipation characterized by constrictive spasms in the intestines, making it difficult for the body to pass stool. This condition is often linked to neurasthenia (a condition marked by chronic fatigue and psychological distress) and can also be associated with certain medical conditions such as lead poisoning. Spastic constipation is […]

Spastic colon, commonly referred to as irritable bowel syndrome (IBS), is a functional gastrointestinal disorder characterized by chronic abdominal discomfort, bloating, and changes in bowel habits. Unlike other gastrointestinal conditions, IBS does not cause visible damage to the digestive tract, but it can significantly impact a person’s quality of life due to its persistent symptoms. […]

Spastic bladder, also known as automatic bladder or reflex bladder, is a form of neurogenic bladder dysfunction caused by damage to the spinal cord. This condition disrupts the normal communication between the brain and the bladder, leading to involuntary and uncontrolled bladder contractions, resulting in various urinary problems. Spastic bladder often causes symptoms such as […]

Spastic aphonia is a speech disorder characterized by an inability to speak due to spasmodic contractions of the muscles in the throat, specifically the abductor muscles that control the vocal cords. This condition leads to sudden, involuntary voice stoppages during speech, making it difficult for the individual to produce sound. It is often classified as […]

Spasticity refers to a condition characterized by abnormal, involuntary muscle contractions or spasms. It often involves an increase in muscle tone and stiffness, making movement difficult. Spasticity typically occurs when there is damage or disruption to the central nervous system pathways that control voluntary movement, often affecting muscles in the arms, legs, and other areas […]

Spasmogen refers to any substance that induces smooth muscle contractions. These contractions can occur in various parts of the body, such as the airways, gastrointestinal tract, and blood vessels, often leading to physiological responses like bronchoconstriction or vasoconstriction. Spasmogens are important in both normal bodily functions and pathological conditions, such as asthma or hypertension. How […]

Spasmodic torticollis, also known as cervical dystonia, is a neurological condition characterized by involuntary, intermittent muscle spasms in the neck that cause the head to twist or tilt to one side. This condition can range from mild to severe, and it can lead to discomfort, pain, and difficulty in performing daily activities. Although the exact […]

Spasmodic tics are repetitive, involuntary muscle movements caused by sudden and brief contractions of a specific muscle group. These tics can vary in intensity and frequency, often occurring at irregular intervals. While spasmodic tics are generally harmless, they can be disruptive and affect a person’s quality of life, especially if they are frequent or severe. […]

Spasmodic stricture refers to the narrowing or constriction of a body passage due to involuntary muscle spasms, rather than a permanent or organic structural change. Unlike strictures caused by inflammation, scarring, or physical blockages, spasmodic strictures are temporary and arise from muscle contractions, which restrict the passage of substances like food, air, or fluids through […]
