What To Expect

Your physician will provide you with a prescription for outpatient therapy along with a diagnosis and expectations for improved function. When you begin therapy at Sibley, a full evaluation will be completed by a physical therapist who will set up a personalized treatment plan based on your goals and limitations.

Therapy programs generally consist of two to three sessions per week for six to eight weeks. Each session aims to help you reach your goals and return you to optimal function. During this process, a reevaluation is made in consultation with your referring physician to help determine whether to continue therapy or discharge with a home program.


Our Therapists

The Sibley rehabilitation team consists of a medical director, physical therapists, occupational therapists and speech therapists, and includes audiology services offered through Washington Hearing and Speech. Many of our therapists have earned specialized certifications and/or had extensive training in various specialty areas, such as geriatrics, hand therapy, lymphedema treatment, wound therapy, gait analysis and women’s health issues. All are licensed to practice in the District of Columbia.

Numerous therapists are also skilled at intramuscular manual therapy (IMT), also known as trigger point dry needling. This procedure involves inserting tiny monofilament needles into muscles to decrease trigger point activity. Trigger points are taut bands within a muscle that may cause local or referred pain, limit muscle flexibility and/or function. IMT is not acupuncture; it uses the anatomical landmarks in the body to locate and treat trigger points to relieve pain and improve function. The physical therapist performing IMT has been trained by a board-approved or Commission on Accreditation in Physical Therapy Education (CAPTE) accredited IMT training program.
