Journal Article
Valentin, S., & Licka, T. F. (2016). Spinal motion and muscle activity during active trunk movements – comparing sheep and humans adopting upright and quadrupedal postures. PLOS ONE, 11(1), Article e0146362. https://doi.org/10.1371/journal.pone.0146362

Sheep are used as models for the human spine, yet comparative in vivo data necessary for validation is limited. The purpose of this study was therefore to compare spinal motion and trunk muscle activity during active trunk movements in sheep and huma...

Background Muscle fatty infiltration (MFI) has been identified in patients with spinal pain using magnetic resonance imaging (MRI). Even though sheep are a commonly used animal model for the human spine, comparative sheep MFI data from MRI is not av...

MRI-determined lumbar muscle morphometry in man and sheep: potential biomechanical implications for ovine model to human spine translation (2015)
Journal Article

The sheep is a commonly used animal model for human lumbar spine surgery, but only in vitro investigations comparing the human and ovine spine exist. Spinal musculature has previously not been compared between man and sheep. This additional knowledge...

Comparative need for spinal stabilisation between quadrupedal and bipedal locomotion (2015)
Journal Article

Sheep are commonly used as an animal model for the human lumbar spine, but similarities in trunk muscle activity of humans and sheep during functional tasks, such as locomotion have not been investigated. Therefore, the aim of the study was to evalua... Read More about Comparative need for spinal stabilisation between quadrupedal and bipedal locomotion.

Inter-rater reliability of trunk muscle morphometric analysis (2015)
Journal Article
Valentin, S., Yeates, T. D., Licka, T., & Elliott, J. (2015). Inter-rater reliability of trunk muscle morphometric analysis. Journal of Back and Musculoskeletal Rehabilitation, 28(1), 181-190. https://doi.org/10.3233/BMR-140552

BACKGROUND: Inter-rater reliability of generalised lumbar extensor muscle CSA has been identified, however, more detailed reliability metrics of individual trunk muscles are lacking. OBJECTIVE: To report muscle volume and muscle fatty infiltrate (MF... Read More about Inter-rater reliability of trunk muscle morphometric analysis.

Kinematic parameters of sheep walking on a treadmill (2014)
Journal Article
Valentin, S., Essigbeck, A., Wolfram, I., & Licka, T. (2014). Kinematic parameters of sheep walking on a treadmill. Veterinary Journal, 202(3), 657-658. https://doi.org/10.1016/j.tvjl.2014.09.028

Ovine locomotion studies are rare, despite their relevance for medical research. The aim of this preliminary study was to investigate habituation and temporospatial parameters during treadmill walking of seven Austrian Mountain sheep. Sheep were naïv...

Age and side-related morphometric MRI evaluation of trunk muscles in people without back pain (2014)
Journal Article

This study evaluated lumbar spine muscle volume and Muscle Fatty Infiltrate (MFI) across two age groups of healthy adults. Twenty-four participants (young group – YG: age 18–25, n = 12; mature group – MG: age 45–60, n = 12) without low back pain unde...

The presence of long spinal muscles increases stiffness and hysteresis of the caprine spine in-vitro (2012)
Journal Article

Long muscle-tendon-units are known to contribute to spinal stiffness and hysteresis in-vivo, yet their contribution as a passive structure in-vitro is less well defined. Twelve full length caprine spines including the head, pelvis and all spinal musc...
