Majcen Rošker, Živa (author), Kristjansson, Eythor (mentor), Vodičar, Miha (co-mentor)

The aim of the thesis was to study; metric characteristics of smooth pursuit neck torsion test (SPNT) in idiopathic neck pain patients (INP) and healthy individuals, relationship between oculomotor functions and subjective visual complaints and presence of cognitive involvement during SPNT test, relationship between sensorimotor functions in INP and healthy and sensorimotor functions between healthy and different patient groups (mild traumatic brain injury (mTBI), whiplash associated disorders (WAD) and INP). Infrared video-oculography was used to measure eye movements, phasic and tonic alertness. Butterfly and relocation test measured cervicocephalic kinaesthesia and force plate postural balance during quiet stance. Major results; SPNT test should be performed at 30°/s velocity and 40° amplitude under 45° of neck torsion, intensity of visual symptoms was related to SPNT, tonic and phasic alertness were altered in neck pain patients, cervicocephalic kinaesthesia was related to postural balance and oculomotor control and differences in sensorimotor control were found between healthy and all patient groups but not between patient groups except for postural balance. Early detection and diagnosis of functional characteristic in patients with neck pain could help towards faster recovery and less reoccurrence.

Abstract

Namen naloge je bil preučiti; merske lastnosti horizontalnega sledilnega pogleda med torzijo vratu (SPTV) pri ljudeh z bolečino v vratu in brez, preveriti povezanost med okulomotoriko in simptomi vidnega zaznavanja ter pomen kognitivnih funkcij med SPTV testom, povezanost med senzorično-motoričnimi sposobnostmi pri bolnikih in zdravimi posameznikih ter razlike v senzorično-motoričnih sposobnostih med bolniki z blažjo travmatsko poškodbo možganov (BPM), idiopatsko bolečino v vratu in nihajno poškodbo vratu (NPV) ter zdravimi posamezniki. Za SPTV in meritve fazične in tonične pozornosti smo uporabili infrardečo video-okulografijo. Metuljni in repozicijski test sta bila uporabljena za vrednotenje cervikocefalične kinestezije, ravnotežje smo merili s ploščo za merjenje reakcijskih sil na podlago. Ključni rezultati: pri SPTV testu je potrebno uporabiti hitrosti 30°/s, amplitude 40°, v 45° torziji vratu, natančnost sledenja tarče je povezana z intenzivnostjo vidnih simptomov, viden je upad tonične in fazične pozornosti pri bolnikih z bolečinami v vratu, vratna kinestezija je povezana z ravnotežjem in okulomotoričnimi funkcijami ter prisotne so razlike v naštetih senzorično-motoričnih funkcijah med zdravimi preiskovanci in skupinami bolnikov (BPM, idiopatska bolečina v vratu in NPV). Zgodnje prepoznavanje in diagnosticiranje funkcionalnih sprememb pri bolnikih bi lahko omogočilo hitrejše okrevanje in zmanjšanje števila remisij.
