| postural | <anatomy> Pertaining to posture or position. (18 Nov 1997) |
|---|---|
| postural albuminuria | The appearance of albumin in the urine when the patient is erect and its disappearance when recumbent. Synonym: orthostatic proteinuria, postural proteinuria, postural albuminuria. (05 Mar 2000) |
| postural contraction | Maintenance of muscular tension (usually isometric) sufficient to maintain posture. (05 Mar 2000) |
| postural drainage | Drainage used in bronchiectasis and lung abscess. The patient's body is positioned so that the trachea is inclined downward and below the affected chest area. (05 Mar 2000) |
| postural hypotension | <cardiology> The manifestation of low blood pressure when rising from a chair or bed. A drop in blood pressure that is precipitated by changes in body position. May be related to hydration status, drug side effect or be caused by a dysfunction in the autonomic nervous systems ability to maintain blood pressure with positional changes (for example autonomic neuropathy secondary to diabetes). (27 Sep 1997) |
| postural ischemia | The reduced blood pressure and flow induced in a part, e.g., the leg or foot, by raising it above the heart level; used to reduce bleeding during surgical operations on the extremities. (05 Mar 2000) |
| postural myoneuralgia | Muscle pain associated with cramped position, stress of standing with improper posture, etc. Origin: myo-+ G. Neuron, nerve, + algos, pain (05 Mar 2000) |
| postural position | The usual position of the mandible when the patient is resting comfortably in the upright position and the condyles are in a neutral unstrained position in the glenoid fossae. See: rest relation. Synonym: postural position, postural resting position, rest position. (05 Mar 2000) |
| postural reflex | Responses that control the position of the trunk and extremities. See: righting reflexes. Synonym: static reflexes. (05 Mar 2000) |
| postural set | An overall motor readiness to respond, as in a runner instructed to get set and on the mark. (05 Mar 2000) |
| postural syncope | Syncope upon assuming an upright position; caused by failure of normal vasoconstrictive mechanisms. (05 Mar 2000) |
| postural tremor | Tremor present when the limbs or trunk are kept in certain positions and when they are moved actively, usually due to near-synchronous rhythmic bursts in opposing muscle groups. Synonym: static tremor. (05 Mar 2000) |
| postural version | Nonmanual version obtained by changing the position of the mother. (05 Mar 2000) |
| postural vertigo | Light-headedness that appears particularly in elderly people with change of position usually from lying or sitting to standing; due to orthostatic hypotension. (05 Mar 2000) |
| drainage, postural | Therapeutic drainage in bronchopulmonary diseases in which there is copious mucus secretion, such as chronic bronchitis, bronchiectasis, pulmonary abscess, or cystic fibrosis. The patient is placed with head downward, so that the trachea is inclined downward and below the affected area. It may be done in 15- to 20-minute sessions or by having the patient sleep in a head-down position. The therapy may be used in conjunction with forced expiration, bronchodilator agents, or expectorants. (12 Dec 1998) |
