The Center for Rheumatology and Bone Research is a division of
Arthritis and Rheumatism Associates, a
twelve-physician Rheumatology practice. Clinical trials are
completed in two locations: northwest Washington, D.C. and Wheaton,
Maryland, a suburb of Washington. Administrative offices for the
Center for Rheumatology and Bone Research are in Wheaton where
support staff serves the needs of both our Maryland and District of
Columbia sites.
The development of the Center stemmed from our desire to
participate in clinical trials in a focused and well-managed
setting, offering contracting companies high quality service while
giving our patients access to new therapies. Our experience in
conducting clinical trials began in 1982 and covers the broad range
of rheumatology including the evaluation of new agents for
RHEUMATOID ARTHRTTIS, OSTEOARTHRITIS, CHRONIC PAIN, BACK PAIN,
OSTEOPOROSIS, SJOGREN'S SYNDROME, TENDONITIS, AND OTHER
CONNECTIVE TISSUE DISEASES.
All of our physicians are board certified in Internal Medicine
and Rheumatology. We have an active teaching affiliation with The
George Washington University School of Medicine and Health Sciences
and the University of Maryland School of Medicine. Members of the
group are active in the American College of Rheumatology, the
American College of Physicians, and the Association of Clinical
Research Professionals.
Our rheumatology practice handles 30,000 patient visits annually
(including 3,000 new patients) in four locations. We see patients
from a wide geographic area that spans from Baltimore, Maryland to
Fredericksburg, Virginia and from Harper's Ferry, West Virginia
to Salisbury, Maryland. We are equipped with a full service, fully
licensed laboratory and on-site x-ray facilities staffed with
licensed radiation technologists. Our Osteoporosis Assessment
Centers provide DEXA testing for bone mineral density measurement
at three locations, and are capable of performing total body DEXA
studies. In addition, we have an excellent physical therapy
division with three full-time registered physical therapists.
