Surface electromyography in animal biomechanics: A systematic review (2015)
Journal Article
Valentin, S., & Zsoldos, R. R. (2016). Surface electromyography in animal biomechanics: A systematic review. Journal of Electromyography and Kinesiology, 28, 167-183. https://doi.org/10.1016/j.jelekin.2015.12.005

The study of muscle activity using surface electromyography (sEMG) is commonly used for investigations of the neuromuscular system in man. Although sEMG has faced methodological challenges, considerable technical advances have been made in the last f...

In vivo magnetic resonance imaging features of spinal muscles in the ovine model (2015)
Journal Article
Valentin, S., Licka, T., Essigbeck, A., & Elliott, J. (2016). In vivo magnetic resonance imaging features of spinal muscles in the ovine model. Journal of Orthopaedic Translation, 6, 1-9. https://doi.org/10.1016/j.jot.2015.09.004

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
Valentin, S., Licka, T. F., & Elliott, J. (2015). MRI-determined lumbar muscle morphometry in man and sheep: potential biomechanical implications for ovine model to human spine translation. Journal of Anatomy, 227(4), 506-513. https://doi.org/10.1111/joa.12354

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...

Subcutaneous fat thickness is not correlated to the magnitude of measurable trunk muscle activity in surface EMG of normal weight healthy adults (2015)
Presentation / Conference Contribution
Valentin, S., Elliott, J., & Licka, T. (2015, July). Subcutaneous fat thickness is not correlated to the magnitude of measurable trunk muscle activity in surface EMG of normal weight healthy adults. Paper presented at XXV Congress of the International Society of Biomechanics (ISB 2015 Glasgow), Glasgow

Introduction and Objectives: Surface Electromyography (sEMG) is a non-invasive tool from which muscle activation parameters can be investigated during a variety of static and dynamic conditions. However, subcutaneous fat overlying a muscle of interes...

Active trunk exercises require more muscle activity in mature than in young adults (2015)
Presentation / Conference Contribution
Valentin, S., & Licka, T. (2015, July). Active trunk exercises require more muscle activity in mature than in young adults. Paper presented at XXV Congress of the International Society of Biomechanics (ISB 2015 Glasgow), Glasgow

Introduction and Objectives: Reductions in muscle strength [1], changes in motor control patterns [2] and muscle morphology [3] are known to occur with ageing. However, the effect of age on trunk muscle activity during active trunk exercises has not... Read More about Active trunk exercises require more muscle activity in mature than in young adults.

Movement control during active spinal range of motion is achieved by a differential use of eccentric and concentric muscle activity (2015)
Presentation / Conference Contribution
Valentin, S., & Licka, T. (2015, July). Movement control during active spinal range of motion is achieved by a differential use of eccentric and concentric muscle activity. Paper presented at XXV Congress of the International Society of Biomechanics (ISB 2015 Glasgow), Glasgow

Introduction and Objectives: Neuromuscular control of the rectus abdominis (RA), obliquus internus (OI), obliquus externus (OE), and erector spinae (ES) muscles has been widely investigated during a range of conditions such as perturbations [1], stab...

Comparative need for spinal stabilisation between quadrupedal and bipedal locomotion (2015)
Journal Article
Valentin, S., & Licka, T. (2015). Comparative need for spinal stabilisation between quadrupedal and bipedal locomotion. Comparative Exercise Physiology, 11(2), 95-105. https://doi.org/10.3920/CEP150008

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.
