We are proud to offer a full line of comprehensive onsite diagnostic procedures for the convenience of our patients and to allow our professional staff to accurately and promptly diagnose patient conditions. From time honored traditional diagnostic measures to sophisticated state-of-the-art diagnostic equipment, our Medical staff is prepared to provide timely evaluations and quality nonsurgical pain and injury care for residents of the East Setauket, Stony Brook area.

Onsite Diagnostics at Action Medical Sports & Rehab, include:

Electrocardiogram (EKG)

An electrocardiogram also known as an EKG or ECG is a non-invasive test that looks at the electrical activity of the heart. In simplest terms, the human heart may be thought of as containing two systems – plumbing and electrical. The electrical system of the heart actuates the pump (heart muscle) sustaining the flow of de-oxygenated blood to the lungs and the flow of oxygenated blood to the cells of the body.

Computerized Range of Motion

Computerized range of motion allows us to procure objective joint range of motion measurements. Our office uses computerized range of motion results to design customized treatments plans and record progress.

Computerized Muscle Testing

Computerized muscle testing is used to obtain objective muscle strength measurements. It may be used for isolated muscles or muscle groups. Computerized muscle testing results assists our medical staff to formulate individualized treatment plans and measure progress with rehabilitation.

Diagnostic Ultrasound

Diagnostic ultrasound is used to create images of joints, cartilage, ligaments, tendons, soft tissues, and muscles to detect and diagnose acute conditions, as well as chronic pain conditions. Diagnostic ultrasound is a brief painless in-office procedure.

Nerve Testing (NCV, DEP, EMG)

Nerve conduction testing is performed to evaluate the function of the nerves for muscle movements and sensation, especially in the presence of numbness, tingling, burning, or weakness. Our onsite nerve conduction velocity (NVC) and electromyography (EMG) assessments mean that our patients can receive the work-up they need onsite at our office.

Ankle Brachial Index

An Ankle Brachial Index, or ABI, is an in-office procedure used to determine if a patient has reduced blood flow to their lower extremities, a disease process called Peripheral Vascular Disease. The ankle-brachial index test compares your blood pressure measured at your ankle with your blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs, leading to circulatory problems, heart disease or stroke.


This test is used to determine the cause of shortness of breath, to rule out any kind of obstructive disease that blocks breathing, or restrictive disease that limits the expansion and capacity of the lungs. Spirometry is most often used to diagnose and monitor lung problems, such as chronic bronchitis, emphysema, pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), or asthma.

Spirometry is also used to monitor how well medications for respiratory problems are working and to evaluate breathing capability prior to surgery.
