Pressure Test in Normal Subjects

Lumbar infusion test in normal pressure hydrocephalus.

OBJECTIVE To compare potential clinical value of plateau pressure (P(pl)), resistance to outflow (R(out)), pulse-pressure amplitude (P(plA)) and rate of pressure increase (v(P)), taken from the constant rate lumbar infusion test (LIT), as predictors for the outcome of shunt surgery. METHODS Recordings from preoperative LIT in 55 patients were scrutinized for the values of P(pl), P(plA), v(P) ...

Macular dazzling test on normal subjects.

The macular dazzling test was performed on 240 healthy eyes, classified into six groups according to the ages of the subjects. The test was used to assess both long distance and short distance vision with a simultaneous study of the influence of mydriasis and miosis. The MDT is a test easy to perform, requires a minimum of co-operation by the subject, and gives repeatable results. The MDT value...

Test-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects

  Abstract   Background: Postural instability has been identified as a potential precursor of   falls in elderly subjects. Postural stability in quiet stance is commonly assessed with   center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure   (COP) measures in the elderly subjects.   Met...
