Medical Research

For more than forty years, Texas Back Institute is committed to providing the highest quality treatments and services for our patients. Our clinical research team stays at the forefront of medical care by initiating studies that advance patient outcomes over time.

Patients can access the latest in clinical studies, peer-reviewed papers, and advanced technology that address trauma, deformity, tumors, and age-related degenerative changes. In some cases, patients are granted access to clinical trials in motion-preserving, minimally invasive and robotics to support their course of treatment

The Spine Biomechanics Laboratory at Texas Back Institute exists to investigate the biomechanical and neuromuscular risk factors associated with spinal ailments in an effort to define the most appropriate and effective treatment options.

This lab is a critical component in bridging the basic science of biomechanics and engineering with the clinical science of spinal care. The clinicians and scientists involved with the lab are uncompromising in furthering the treatment of spinal pathology and translating that knowledge into advanced care to for the patients we serve.
