Posterior pelvic tilt (PPT) exercises are frequently used in back rehabilitation, although the immediate effect of PPT in people not educated in this exercise is unknown. This study evaluated the effect of PPT in healthy participants on pelvic angle... Read More about Trunk muscle activity is independent of angle achieved in posterior pelvic tilt.

The presence of long spinal muscles increases stiffness and hysteresis of the caprine spine in-vitro (2012)
Journal Article
Valentin, S., Groesel, M., & Licka, T. (2012). The presence of long spinal muscles increases stiffness and hysteresis of the caprine spine in-vitro. Journal of Biomechanics, 45(15), 2506-2512. https://doi.org/10.1016/j.jbiomech.2012.07.022

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...

The effect of loading on the equine spine - a preliminary study (2010)
Journal Article
Valentin, S., Davis, R., Wilson, A., & Pfau, T. (2010). The effect of loading on the equine spine - a preliminary study. Wiener Tierärztliche Monatsschrift, 97, 74-80

Although equine spinal motion has been analysed in vivo and in vitro, spinal pathophysiology and the mechanisms of injury are not well understood. Most horses are exercised mounted, yet the effect of a load on the spine is still unclear. The purpose... Read More about The effect of loading on the equine spine - a preliminary study.

Cincinnati Orthopaedic Disability Index in canines (2009)
Journal Article

General description: The Cincinnati Orthopaedic Disability Index (CODI) is a case-specific questionnaire completed by owners of dogs with orthopaedic disease, to measure individual functional status of the dog (Gingerich and Strobel 2003). Owners are... Read More about Cincinnati Orthopaedic Disability Index in canines.

Dry needling and exercise for chronic whiplash - a randomised controlled trial (2009)
Journal Article
Sterling, M., Valentin, S., Vicenzino, B., Souvlis, T., & Connelly, L. B. (2009). Dry needling and exercise for chronic whiplash - a randomised controlled trial. BMC Musculoskeletal Disorders, 10, Article 160. https://doi.org/10.1186/1471-2474-10-160

Chronic whiplash is a common and costly problem. Sensory hypersensitivity is a feature of chronic whiplash that is associated with poor responsiveness to physical treatments such as exercise. Modalities such as dry-needling have shown some capacity t... Read More about Dry needling and exercise for chronic whiplash - a randomised controlled trial.
