Professor Omid Khaiyat

Sports and Exercise Science/Sport Rehabilitation
0151 291 3262

Professor Khaiyat is currently a Professor of Musculoskeletal Physiology and Health and Associate Dean of School of Health and Sport Sciences at Liverpool Hope University. He was graduated in Medicine in 1995 (MD) and obtained PhD in Musculoskeletal Science (Sports Medicine) from the University of Liverpool in 2006. He is a fully GMC-registered medical practitioner and holds honorary contract with the Royal Liverpool and Broadgreen University Hospitals NHS Trust (Upper Limb Unit - Orthopaedic and Trauma) and University of Liverpool (Musculoskeletal Biology).


Professor Khaiyat’s research focuses on using EMG in combination with other technologies to investigate normal muscle function/health, musculoskeletal pathologies, and evidence-based rehabilitation with a particular focus on upper limb. He has established a comprehensive biomechanics lab with access to speciality labs, on-site physiotherapy and sport rehabilitation clinic, and S&C suite.


He is currently the lead investigator for several RCTs including  Exercise and Nutrition Interventions in Age-related Sarcopenia, Impact of intravenous iron (Ferinject) on musculoskeletal function profiles in older adults with Iron Deficiency Anaemia (IDA), and Kinematics And Muscle Activation Profiles In Reverse Shoulder Arthroplasty. He is supervisor for several PhD projects.


Professor Khaiyat is the chair of the biannual Shoulder Rehabilitation Conference with the 3rd conference titled as “Zebras and Horses: Thinking outside the box in shoulder pain” to take place in November 2022. He is currently a member of scientific committee for European Society for Shoulder and Elbow Rehabilitation (EUSSER) and collaborator of the English Institute of Sport (EIS) for upper limb research.


My research interests:

· Integrated Kinematic (Motion Capture) and Kinetic (EMG, Force) studies of: Daily Activities; Musculoskeletal conditions (Upper extremity in particular);

  Sporting Activities;  Sport Injuries;  Rehabilitation Exercises;  Ageing/Sarcopenia

· Outcome measurements and Health-related quality of life in musculoskeletal conditions

· The Impact of physical activity and exercise on muscle properties in adults and older people

2. The influence of Kinetic Chain sequencing on throwing performance in athletes with and without shoulder injuries

3. The multidimensional effect of supervised moderate exercise training on musculoskeletal function and health-related quality of life in age-related sarcopenia

4. An investigation into the effect of nutritional supplementation and exercise training on musculoskeletal function and health related quality of life in age-related sarcopenia

5. An investigation into the body composition, nutritional status and fitness of elite Hurling players in Ireland

6. Investigating the visuomotor and cortical mechanisms behind learning to use a prosthetic hand

7. Complex Shoulder Instability (Functional MRI and EMG)

8. Improving Coordination in Children with developmental coordination disorder (DCD)
