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.


Specialized Rehabilitation Equipment

Integrated Therapy System

Sibley Outpatient Rehabilitation offers the latest technologies, including an interactive 55” touchscreen software that features diverse programs that challenge physical, occupational and speech therapy patients to improve performance and function in visual motor tasks, auditory and visual processing, cognitive skills and endurance training. The program is able to gather baseline data and track progress over the course of treatment to improve therapists’ feedback to rehabilitation patients.

Overhead Lift

Installed in January 2021, the brand new overhead lift system in our outpatient rehabilitation gym allows patients to challenge balance, strength and endurance during their physical therapy sessions without the fear of falling! This lift can be used with a variety of populations, such as stroke and orthopedics.

Body Composition Analysis

Since 2020, the Lymphedema Program at Sibley Outpatient Rehabilitation has offered state-of-the-art body composition analysis to monitor and track changes in edema for our physical and occupational therapy patients recovering from cancer treatments. In addition, this system can track changes in body fat, muscle mass and basal metabolic rate.

Running and Gait Analysis

Our motion analysis equipment consists of light-emitting diode (LED) markers, several high-speed video cameras and specialized analytics software. The LED markers are placed in several locations along the side of your body. As you walk or run, the video cameras capture the movement in real time. The LED markers help us see the exact position of your joints in relation to each other. With the help of this specialized software, we analyze your gait and identify problem areas.

Our Therapists

The Sibley rehabilitation team consists of a medical director, physical therapists, occupational therapists and speech therapists. 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.
