Uvod: Mišična zmogljivost je pomembna telesna funkcija, ki se ocenjuje v sklopu fizioterapevtskega pregleda. Na razpolago so različne metode testiranja mišične zmogljivosti, med katere spada tudi ročna dinamometrija. Ročna dinamometrija omogoča kvantificirano, objektivno merjenje mišične sile, je enostavna in priročna za klinično uporabo ter cenovno dostopna. Namen: Namen diplomskega dela je bil ovrednotiti ponovljivost in zanesljivost izometrične dinamometrije mišic trupa z ročnim dinamometrom. Metode dela: V raziskavi je sodelovalo 30 zdravih preiskovank povprečno starih 21,9 (1,3) let. Meritve smo izvedli v dveh sejah v razmiku 48 ur. Preiskovanke so izvedle eno submaksimalno kontrakcijo za seznanitev s postopkom meritev in v vsaki seji tri maksimalne izometrične kontrakcije posamezne mišične skupine. Rezultati: Pri zaporednih meritvah maksimalne izometrične sile lateralnih fleksorjev trupa v desno v prvi seji, rotatorjev trupa v desno in rotatorjev trupa v levo v drugi seji je bila statistično pomembna razlika. Statistično pomembna razlika se je izkazala tudi pri prvi meritvi med prvo in drugo sejo pri ekstenzorjih, lateralnih fleksorjih v desno ter rotatorjih trupa v levo. Ponovljivost meritev je bila zmerna do odlična. Najnižja vrednost intraklasnega koeficienta korelacije je bila opažena pri meritvah sile rotatorjev trupa v desno v prvi seji (IKK = 0,702), najvišja pa pri meritvah sile lateralnih fleksorjev trupa v levo v drugi seji (IKK = 0,923). Odlična zanesljivost se je izkazala pri meritvah sile rotatorjev trupa v levo (IKK = 0,966), pri vseh ostalih mišičnih skupinah pa je bila zanesljivost dobra (IKK = 0,817 – 0,891). Ugotovljena je bila statistično značilna srednja negativna povezanost med telesno višino in maksimalno izometrično silo rotatorjev trupa, telesno maso in silo rotatorjev trupa, med ITM in silo rotatorjev trupa v desno v drugi seji ter med ITM in silo rotatorjev trupa v levo. Razprava in zaključek: Ročna dinamometrija je ponovljiva in zanesljiva metoda za ocenjevanje maksimalne izometrične sile mišic trupa. V prihodnje bi bilo treba izvesti meritve tako na ženskah kot na moških ter primerjati rezultate meritev med različnimi preiskovalci.

• Title: Repeatability and reliability of isometric dynamometry of trunk muscles using a hand-held dynamometer : diploma work

Abstract

Introduction: Muscle performance is an important physical function that is assessed as part of a physiotherapy examination. There are several methods for testing muscle performance, including hand-held dynamometry. Hand-held dynamometry provides a quantified, objective measurement of muscle strength, is simple, affordable, and suitable for clinical use. Purpose: The aim of this work was to investigate the repeatability and reliability of isometric trunk muscle dynamometry using a hand-held dynamometer. Methods: Thirty healthy women with an average age of 21.9 (1.3) years participated in the study. The measurements were performed in two sessions within a 48-hour interval. In each session, subjects performed one submaximal contraction to familiarise themselves with the measurement procedure and three maximal isometric contractions of each muscle group. Results: Statistically significant differences were found between the consecutive measurements of maximal isometric muscle force of the right lateral trunk flexors in the first session, the right trunk rotators, and the left trunk rotators in the second session. A statistically significant difference was also found in the first measurement between the first and second sessions for the extensors, right lateral flexors, and left trunk rotators. The repeatability of the measurements ranged from moderate to excellent. The lowest intraclass correlation coefficient value was found for the right trunk rotators force measurements in the first session (ICC = 0.702), while the highest value was found for the left lateral flexors force measurements in the second session (ICC = 0.923). Excellent reliability was found for left trunk rotators force (ICC = 0.966) and good reliability for all other muscle groups (ICC = 0.817 – 0.891). A statistically significant, moderately negative correlation was found between body height and maximum isometric trunk rotators force, body weight and trunk rotators force, body mass index and right trunk rotators force in the second session, and body mass index and left trunk rotators force. Discussion and conclusion: The hand-held dynamometry is a repeatable and reliable method for assessing maximal isometric force of the trunk muscles. In the future, measurements should be performed in both women and men, and the results of the measurements should be compared between different examiners.
