Abstract
Grafički prikaz neuromuskularne podražljivosti el ektričnim četvrtasl.im impulsima u
obliku intenzitetnovremenske krivulje, u Hrvatskoj se od 1962. godine izvodi u
el ektrod ij agnostičkom laboratoriju Klinike za fizikalnu medicinu, rehabilitaciju i
reumatologiju Kliničke bolnice "Sestre milosrdnice". Za takav prikaz postoji nekoliko
naziva: intenzitetnovrernenska krivulja (1/t krivulja), elektrostatograrn (ELS) ili
jakosnovremenska krivulja (SD krivulja). Od 1990. u našem se elektrod ijagnostičkom
laboratoriju neuromuskularna podražljivosl električnim četvrtatstim impulsima, osim
prikazivanja l/t krivuljom, prikazuje i intenzitetnovremenskim pravcem (l/L pravac).
Prikazivanje neuromuskularne podražljivosti u obliku pravca, ima nekoliko važnih
prednosti u odnosu na prikazivanje krivuljom. Prednosti su mogućnost odrcdenja kuta,
raspona i položaja pravca u koordinatnom sustavu, lakša usporedba motornih i senzornih
pravaca i druge. Ti novi elementi svojstveni pravcu, omogućuju bolju dijagnostičku i
prognostičku procjenu te neposredno i bolji terapijski pristup. Predlažemo, s toga, da se u
budućoj elektrodijagnostičkoj obradi, uz dosadašnju 1/t krivulju, upotrebljava i 1/t pravac
jer sa svojim parametrima pravac daje veće elektrodijagnostičke mogućnosti.Since 1962. the graphic presentation of the neuromuscular excitability, provoked
by electric rectangular impulses, in the fonn of the intensity-duration curve has been used
in Croatia, in the Electrodiagnostic Laboratory of the Clinical Department of Physical
Medicine, Rehabilitation and Reumatology al "Sestre milosrdnice" University Hospital.
This graphic presentation has had three alternative names: intensity-duration curve (1/t curve}, electrostatogram (ELS) and strength-duration curve (SD curve). Since 1990. in this
electrodiagnostic laboratory the neuromuscular excitability provoked by electric
rectanguJar impulses has been presented also in the form of line (lit line), beside the
presentation in the form of curve (1/t curve). Presentation of the neuromuscular excitability
in the form of the line has several important benefits compared to the presentation in the
form of the curve. TI1ese benefits are possibility of the precise determination of the angle,
range and the position of the line in the coordinate system as well as the easier comparison
of the "motor" lines and the "sensor" lines. The new parameters, characteristic for the line,
provide more reliable diagnostic and prognostic evaluation as well as better therapeutic
approach. On the basis of these facts we have proposed the use of the 1/t line in the
electrodiagnostic routine measurement, beside the l/t curve. Namely, parameters of the 1/t
line in comparison to the l/t curve provides broader electrodiagnostic possibilities
