|---|---|
| spastic colon | A bowel disorder with no demonstrable organic abnormality. Often referred to as a functional bowel disorder or spastic colon. Symptoms include episodic, crampy abdominal pains often related to anxiety. (27 Sep 1997) |
| spastic diplegia | A type of cerebral palsy in which there is bilateral spasticity, with the lower extremities more severely affected. Compare: flaccid paralysis. Synonym: Erb-Charcot disease, infantile diplegia, Little's disease, spastic spinal paralysis, tabes spasmodica. (05 Mar 2000) |
| spastic dysarthria | Dysarthria caused by lesions along the corticobulbar tracts. Synonym: rigid dysarthria. (05 Mar 2000) |
| spastic dysphonia | A spasmodic contraction of the intrinsic muscles of the larynx excited by attempted phonation, producing either adductor or abductor subtypes caused by central nervous system disease. A localised form of movement disorder. Synonym: phonic spasm, spastic dysphonia. (05 Mar 2000) |
| spastic ectropion | Ectropion of the lower eyelid as a result of ocular irritation. (05 Mar 2000) |
| spastic entropion | Entropion that arises from excessive contracture of the orbicularis oculi muscle. (05 Mar 2000) |
| spastic flat foot | Eversion of the foot with spasm of the muscles (peroneal) on the outer side; often associated with abnormal bars of bone cartilage or fibrous tissue between the calcaneum and the navicular (scaphoid) or between the navicular and the talus, resulting in a tarsal coalition. (05 Mar 2000) |
| spastic gait | Gait in which the leg is stiff, without flexion at knee and ankle, and with each step is rotated away from the body, then towards it, forming a saemicircle. Synonym: circumduction gait, spastic gait. (05 Mar 2000) |
| spastic hemiplegia | A hemiplegia with increased tone in the antigravity muscles of the affected side. (05 Mar 2000) |

| spastic paraplegia, hereditary | An insidiously progressive inherited disorder (probably autosomal dominant) characterised by distal limb weakness. Stiffness of the legs in walking due to the spasticity marks the onset of the disorder. Peripheral sensory neurons may be affected in the later stages of the disease. (12 Dec 1998) |
| spastic pseuodoparalysis | Better known as creutzfeldt-jakob disease (cjd). A dementing disease of the brain. It is believed due to an unconventional (not a bacteria or virus), transmissible agent called a prion. Symptoms of cjd include forgetfulness, nervousness, jerky trembling hand movements, unsteady gait, muscle spasms, chronic dementia, balance disorder, and loss of facial expression. Cjd is classified as a spongiform encephalopathy. most cases occur randomly (sporadically), but inherited forms exist. There is neither treatment nor cure for cjd. Other names for cjd include creutzfeldt-jakob syndrome and jakob-creutzfeldt disease. (12 Dec 1998) |
