| muscle spasm | <physiology> Painful involuntary muscle contractions. Often seen in skeletal muscle after acute injury (muscle strain). (07 Apr 1998) |
| habit spasm | <clinical sign> An involuntary compulsive, repetitive, stereotyped movement, resembling a purposeful movement because it is coordinated and involves muscles in their normal synergistic relationships, tics usually involve the face and shoulders. (18 Nov 1997) |

| salaam spasm | In infants, a drop of the head on the chest due to loss of tone in the neck muscles as in epilepsia nutans, or to tonic spasm of anterior neck muscles as in West's syndrome, in adults, a nodding of the head from clonic spasm's of the sternomastoid muscles. Synonym: salaam attack, salaam spasm, spasmus nutans. (05 Mar 2000) |

| hemifacial spasm | Tonic spasm of the muscles supplied by the facial nerve, confined to one side. (12 Dec 1998) |
| progressive torsion spasm | A genetic, environmental, or idiopathic disorder, usually beginning in childhood or adolescence, marked by muscular contractions that distort the spine, limbs, hips, and sometimes the cranial-innervated muscles. The abnormal movements are increased by excitement and, at least initially, abolished by sleep. The musculature is hypertonic when in action, hypotonic when at rest. Hereditary forms usually begin with involuntary posturing of the foot or hand (autosomal recessive form ) or of the neck or trunk (autosomal dominant form ); both forms may progress to produce contortions of the entire body. Synonym: progressive torsion spasm, torsion disease of childhood, torsion dystonia, Ziehen-Oppenheim disease. (05 Mar 2000) |
| histrionic spasm | Involuntary twitching of the facial muscles, sometimes unilateral. Synonym: Bell's spasm, convulsive tic, facial spasm, histrionic spasm, mimic convulsion, mimic spasm, mimic tic, palmus, prosopospasm. (05 Mar 2000) |

| spasm | 1. <physiology> A sudden, violent, involuntary contraction of a muscle or a group of muscles, attended by pain and interference with function, producing involuntary movement and distortion. 2. A sudden but transitory constriction of a passage, canal or orifice. Origin: L. Spasmus, Gr. Spasmos (18 Nov 1997) |
| spasm of accommodation | Excessive contraction of the ciliary muscle. (05 Mar 2000) |
| nictitating spasm | Involuntary spasmodic winking. Synonym: spasmus nictitans, winking spasm. (05 Mar 2000) |
| nodding spasm | In infants, a drop of the head on the chest due to loss of tone in the neck muscles as in epilepsia nutans, or to tonic spasm of anterior neck muscles as in West's syndrome, in adults, a nodding of the head from clonic spasm's of the sternomastoid muscles. Synonym: salaam attack, salaam spasm, spasmus nutans. (05 Mar 2000) |
