Introduction: The goal of the present study was to determine the effects of pro-
longed, intermittent flexion on trunk neuromuscular control. Furthermore, the
potential beneficial effects of passive upper body support during flexion were
investigated. Methods: 21 healthy young volunteers (10 females) participated
during two separate visits in which they performed 1 hour of intermittent 60
seconds flexion and 30 seconds rest cycles. Flexion was set at 80% lumbar flex-
ion and was performed with or without upper body support. Before and after
intermittent flexion exposure, lumbar range of motion was measured using in-
ertial measurement units and trunk stability was assessed during perturbations
applied in the forward direction with a force controlled actuator. Two-way re-
peated measures ANOVA was used to compare the results. Results: Trunk ad-
mittance gain decreased after unsupported flexion(p = 0.024), while reflex gain
and lumbar range of motion increased after both conditions(p < 0.001). Signif-
icant interaction effects confirmed a larger increase in lumbar range of mo-
tion and reflex gains following unsupported flexion in comparison to support-
ed flexion (p = 0.025). Discusion and Conclusions: In contrast with some previous
studies we found that prolonged intermittent flexion decreased trunk admit-
tance, which implies an increase of the lumped intrinsic and reflexive stiffness.
Key words: Trunk stability, postural reflexes, muscle activity, low back pain.

Izhodišča: V delovnem okolju na zaposlene vplivajo različni, tudi škodljivi de-
javniki, ki so lahko vzrok za bolniško odsotnost. Najpogostejši razlogi bolniške
odsotnosti v Skupini Slovenske železnice so bolezni mišično-skeletnega sistema,
poškodbe in zastrupitve izven dela ter duševne in vedenjske motnje. Metode:
V prispevku je predstavljena bolniška odsotnost (brez odsotnosti zaradi nege)
zaposlenih v Skupini Slovenske železnice v obdobju med leti 2007 in 2015. V
pregled smo vzeli štiri profile delovnih mest, in sicer dva profila enoizmenskih
delavcev (pisarniški delavci in vzdrževalci železniške infrastrukture) ter dva pro-
fila večizmenskih delavcev (strojevodje vlaka in vozovni pregledniki). Rezultati:
Z enosmerno analizo variance smo ugotovili, da je bil najvišji odstotek bolniške
odsotnosti pričakovano ugotovljen pri vzdrževalcih železniške infrastrukture
(6,38 ± 0,95 %), ki so jim sledili strojevodje (4,49 % ± 1,39 %), pisarniški delav-
ci (4,23 ± 0,58 %) in vozovni pregledniki (3,28 % ± 0,62 %). Diskusija in zaključki:
