Research

PhD project title:

The influence of growth on emu (Dromaius; Aves) musculoskeletal biomechanics: an integrative experimental and modeling analysis

By acquiring in vivo data of the mechanical strains occurring in the long bones of the pelvic limb we will characterise their mechanical environment and how it changes as the animals grows. Together with kinetic and kinematic data we will construct computerised models of locomotion (SIMM) and material models of each bone using the Finite Element method. These models will allow for predictions of bone development and the influence of the mechanical environment in this process.

The application of these models are diverse: these predictions will allow for a detailed study of developmental disorders and clinical approaches to their management as well as greatly reducing the need for in vivo experimentation.

For the first time data of this kind and detail will be available for any species (full limb strain patterns) and more so across an ontogenetic series.

This unprecedented approach to study ontogenetic scaling and adaptation will produce the most robust and models to date as we will be able to validate them against real data.

Why Emus?

Emus grow extremely fast and also a lot! They multiply their body weight approximately 40x before reaching adulthood. This makes them a useful model to study development since changes will be more evident with such an exacerbated growth pattern.

Emus are bipedal and have been shown to share similarities with certain human joints.

Many skeletal problems affect the ratite industry, we hope that our results will be able to help solve or at least prevent some of them.

Emus are extant birds closely related to many extinct animals and are therefore interesting subjects to study from a paleontological perspective.

Dr Anna Liedtke

Anna is currently employed by the University of Birmingham as a Postdoc for the School of Sports Exercise and Rehabilitation Sciences. 

Biography

Anna graduated in 2006 with a BSc. (Hons) in Veterinary Science (now Bioveterinary Science) from The Royal Veterinary College (RVC), University of London. Her bachelor project, supervised by Prof. Janet Patterson-Kane, looked into age related changes in connexin protein expression in equine superficial digital flexor tendons. This then extended into a Pfizer sponsored summer studentship comparing her findings in the horse to human Achilles tendons. Anna then decided to continue her undergraduate studies graduating with a BVet. Med. from the RVC. Her project, supervised by Dr. Richard Piercy, looked into gross and histological characterisation of the equine sacrocaudalis dorsalis muscles in the context of diagnosing Equine Motor Neuron disease and Polyneuritis Equi.This has led her to further her research interests, particularly in the fields of neuromechanics and neuromuscular disorders. Anna subsequently undertook a PhD at the RVC, supervised by Dr. Andrew Spence and Prof. John Hutchinson, in comparative sensory biomechanics.

Research

Anna's PhD project title was: Comparative sensory biomechanics of locomotion in horses, dogs and insects

This project focused on how animals use sensory feedback in the neural control of locomotion. By comparing legged animals of different size and morphology, Anna explored general understanding of how legged animals control their locomotion. This basic knowledge of how the nervous system underlies locomotion can bring fundamental insight into the aetiology of both veterinary and human diseases.

Dr Becky Parkes

Biography

Becky graduated from the RVC in 2006 with a BSc (Hons) in Veterinary Sciences. During this course, she developed an interest in research and undertook several interesting projects. These included her final year research project investigating the limitations of human detection of asymmetry in lame horses with Dr. Renate Weller and Dr. Thilo Pfau, and a summer studentship developing a cat abominal palpation simulator with Prof. Sarah Baillie. Becky then went on to train as a vet and graduated from the RVC in 2010 with a BVetMed degree. During this time she developed an interest in equine orthopaedics and undertook a research project investigating the effect of weather conditions on white line disease in the donkey.

Following graduation, Becky spent a year as an intern at the Animal Health Trust in Newmarket, working for Dr Sue Dyson. She spent her time learning more about equine lameness diagnosis and diagnostic imaging and conducting a study into the risk factors and clinical features of palmar foot pain in the horse. After this, she spent six months doing something completely different- volunteering as a vet at Animal Care Egypt.

Inspired by spending time in the gallops at Newmarket, Becky returned to the Structure and Motion Lab in April 2012 to complete a PhD in racehorse biomechanics under the supervision of Dr Thomas Witte.

Research

PhD project title: "Intrinsic and extrinsic factors affecting the loading environment of the equine distal limb".

This project used non-invasive techniques to investigate the effect of training and running under different conditions- such as on a curve, on different surfaces and on an incline - on stride parameters in young racehorses. The aim being to gain an insight into the adaptations of gait and feed this into research on injury prevention.

Sharon successfully defended her PhD in 2014.

Biography

Sharon graduated from Sparsholt College in 2004 with a BSc (Hons) degree in Equine Studies. Following this she spent a year conducting nutrition and exercise physiology research assisting Dr Joe Pagan at Kentucky Equine Research in the US. She was subsequently employed as a Technician in the Structure and Motion Lab until she started her PhD in October 2009. This project was entitled ‘Basic principles of foot design, locomotor impact mechanics and pathology in large mammals’ under the supervision of Dr John Hutchinson, Dr Renate Weller and Dr Olga Panagiotopoulou.  See more.

Email: sharon8348@hotmail.co.uk

Research

During locomotion, the foot functions to support, stabilise, brake and propel the body, whilst accommodating locomotor forces and providing necessary friction. Despite having to achieve equivocal functions, mammalian foot design is highly variable with regards to anatomy, biology and locomotor behaviour. By comparing impact mechanics in two extreme foot designs (i.e. that of the horse and elephant) my work will reveal how foot morphology and loading behaviour influences the incidence and prevalence of foot disease.

A major goal of my PhD work has been to characterise features of foot impact in hoofed mammals of increasing size in order to understand how body size influences mechanics. For example, how does a 3000kg elephant mitigate ~150kg of foot mass colliding with the ground every step? My current work focusses on the role of the digital cushion in shock absorption and how impact vibrations are attenuated in horses and elephants. I look forward to becoming involved in investigating the influence of captivity/domesticity on foot structure and function in the future.

Dr Alison Wills

Alison Wills

Alison completed her PhD with the RVC in 2014. She has since commenced working within the Animal and Land Sciences Research Team at Hartpury College.

Biography

Alison graduated from the Royal Veterinary College with a BSc in Veterinary Sciences in 2009. She subsequently undertook a BBSRC funded PhD position with the Structure & Motion Laboratory examining the locomotion of free ranging sports dogs and other animals that form social groups.

Email: Alison.Wills at hartpury.ac.uk

Research

Alison is interested in understanding how packs interact and co-operate for mutual benefit. Examples of this are sports dogs which hunt as a group, e.g. fox hounds, beagles and Painted/African hunting dogs which are reported to need a minimum pack size of 6 to successfully catch their prey and prey animals like sheep which have a complex social hierarchy [1].

Sheep are similar to dogs as they exhibit flocking behaviour in the same way that dogs form packs. It has been repeatedly proven that sheep are much more intelligent than was previously believed. They can discriminate between sheep, humans and other animals and can also recall the faces of 50 other sheep for a period of over two years [2]. Sheep are also able to self-medicate, which means that on ingestion of a foodstuff that causes them discomfort (for example indigestion) sheep will then select the correct food from a variety offered to cure their complaint [3].
