About Ram Haddas, PhD, MEng, MSc

Dr. Ram Haddas is Director of Research at the Texas Back Institute Research Foundation in Plano, TX. He founded and built the Spinal Biomechanics Laboratory at Texas Back Institute—the first spine-related human movement biomechanics lab to be incorporated within a US hospital.

In the past year, the Spine Biomechanics Laboratory has assessed over 100 patients. The estimated number of patient visits for 2017 is between 250 and 300. The Lab is currently actively studying patients with scoliosis, myelopathy, back pain, and total disc replacement. Clinical research has been reported at more than 30 international spine meetings.

Dr. Haddas received his Master of Science from Indiana University, Department of Kinesiology in Bloomington, IN. He gained his Master of Engineering degree from Texas Tech University, Department of Engineering in Lubbock, TX. At Texas Tech University Health Sciences Center, Department of Rehabilitation Science, also located in Lubbock, he received a Doctor of Philosophy.

Dr. Haddas is a leader innovator in the development of rehabilitation techniques and technologies for spine-related injuries and disorders. He has published his research in peer-reviewed journals and presents study findings extensively at national and international meetings. Furthermore, he is an invited peer reviewer for many journals, including Archives of Physical Medicine and Rehabilitation, Clinical Biomechanics, Journal of Athletic Training.  Journal of Electromyography and Kinesiology, Journal of Orthopaedic & Sports Physical Therapy, Journal of Sport Rehabilitation, and The Spine Journal.

Furthermore, he is an active member of many prestigious professional organizations: International Society for the Advancement of Spine Surgery, North American Spine Society, Orthopaedic Research Society, American Society of Biomechanics, American Society of Mechanical Engineers, and Gait and Clinical Movement Analysis Society.
