What is Physiatry?

Physiatry is a specialty that focuses on managing various conditions involving the nervous and musculoskeletal systems, helping improve overall function, maintain independence, and improve quality of life. Physiatry focuses on the whole individual, from physical and emotional health to vocational and social needs.

Physiatrists work with other physicians and physical and occupational therapists to treat the whole person.

The HMG Physiatry Team

  • Board-certified in occupational medicine by the American Board of Preventive Medicine, Frederick Terry, DO has over 12 years of experience in providing physiatry care for patients of the Tri-Cities. Skilled in the evaluation of musculoskeletal and neurological issues, Dr. Terry utilizes laboratory testing, x-rays, MRIs, electromyography (EMG), and nerve conduction studies (NCS), to diagnose and treat a variety of conditions. Within the HMG Family of Care, Dr. Terry’s patients benefit from a multi-disciplinary approach, providing his patients with preferred access to over 30 medical specialties, three state-of-the-art outpatient diagnostic centers, and two of the region’s most highly rated outpatient surgery centers.

    “I believe that as a provider, listening is one of the most valuable diagnostic tools available to me,” said Dr. Terry. “I learn more about what is affecting and concerning my patients by listening to them and those closest to them. Often, these conversations provide invaluable insight and always create the strongest patient-physician relationships. My goal is to educate my patients in layman’s terms about their condition and treatment options to enable them to play an active role in developing their treatment plan.”

  • Mark Mehlferber, PA-C has provided care within orthopedics and neurosurgery for over 25 years and is well versed in treating various musculoskeletal conditions. He and Dr. Terry have worked together for over 12 years to provide care to Tri-Cities patients. Mark believes that education is key to quality outcomes. He measures success by how well a patient understands their illness and the effectiveness of the care plan they set together.

    “I make sure to communicate and explain each diagnosis in easy-to-understand terms. It’s important that each patient fully understand their condition so we can work together to create a manageable care plan for them and yield positive results.”
