Center for Rehabilitation Research


The Center for Rehabilitation Research (CRR) is an internationally renowned research, education and clinical assessment center at Texas Tech University Health Sciences Center that serves Lubbock and the West Texas region. The CRR is dedicated to improving the lives of people who have functional limitations caused by physical impairments. The CRR conducts research that emphasizes improving quality of life by preventing disorders that lead to disability and restoring function. The CRR was established in 2002, is part of the School of Health Professions, and is administered through the Department of Rehabilitation Sciences at Texas Tech University Health Sciences Center.

Committed to excellence in research, education, and service the mission of the Center for Rehabilitation Research at TTUHSC is to foster intellectual discovery in rehabilitation science by enabling faculty to produce research, students to learn to conduct research, and by providing rehabilitation assessment services to assist health care professionals in the care of patients.

The CRR consists of six core faculty members and one staff member from the Department of Rehabilitation Sciences, four clinical research laboratories, and a multipurpose conference room / patient reception area. Faculty of the CRR conduct research designed to advance knowledge that will support and inform the evidence-based clinical practices used within physical rehabilitation professions, such as physical therapy, occupational therapy, and athletic training. Faculty members of the CRR also collaborate with other faculty and students from TTUHSC, TTU, and researchers and clinicians from around the world.

Research Laboratories

The CRR laboratories are located on the third floor of the Texas Tech University Health Sciences Center building in Lubbock, Texas. The conference room / patient reception area is the main entrance (room 3C145). The research laboratories are:

  • Clinical Anatomy Research Laboratory
  • Clinical Biomechanics Research Laboratory
  • Clinical Musculoskeletal Research Laboratory
  • Clinical Postural Control Research Laboratory


Faculty members of the CRR are involved in several areas of research designed to improve the understanding of functional impairments, their prevention, and rehabilitation. Research interests of the faculty include:

  • Anatomical aspects of various musculoskeletal disorders
  • Balance, falls, postural control, and vestibular disorders
  • Normal and impaired gait performance
  • Clinical interventions for improving gait and balance
  • Clinical outcomes in orthopedic manual therapy
  • Lower extremity injury mechanisms and prevention during physical activity
  • Neural dynamics
  • Validity and reliability of orthopedic clinical testing

Research Mentoring

Faculty members of the CRR work with graduate students from a variety of programs at TTUHSC and TTU. We mentor doctoral (PhD, ScD, DPT) and master’s (MS, MAT, MOT) students. Additionally, we partner with the PhD in Rehabilitation Sciences program offered by the Department of Rehabilitation Sciences.

Services to the Community

Clinical Services

The CRR currently offers balance assessment and gait analysis services. Individuals seeking clinical services are typically referred to the CRR for testing by their physician or treating clinician. Individuals seeking services but who do not have a referral can make cash payment for services at the time of testing.

Contract Services

We welcome inquires about contract testing services that we can provide. We have the capability of offering several forms of biomechanical, musculoskeletal, neurological, and physiological testing.
