A cerebral vascular accident (CVA, or stroke) occurs when blood supply to an area of the brain is interrupted or reduced. Side effects from a stroke are related to the area of the brain that is obstructed from blood flow and how much tissue is affected. Because of how a CVA affects the body and muscles, it is very important to receive physical therapy services after a stroke. A physical therapist should see a stroke survivor immediately after the CVA and periodically after the stroke due to the progressive changes that can occur with muscle ability, weakness, and range of motion. In order to receive physical therapy services, a physician must write an order for PT. Next, the patient can choose a physical therapy clinic. It is a good idea to call and check on schedule availability, insurance being in network and necessary co-pays when deciding on where to receive physical therapy. On the first visit, an evaluation is completed by a licensed physical therapist to assess the patient’s current level of strength and muscle weakness, overall endurance, gait abnormalities, range of motion, and sensory deficits, as well as specific concerns and goals the patient would like to achieve. The PT will recommend an individualized plan of care with a frequency that is manageable for the patient. Hemiparesis is weakness on one side of the body (either the left or right side) and is usually addressed in PT. According to the National Stroke Association, hemiparesis affects 8 out of 10 stroke survivors. This one-sided weakness can affect any or all muscles on the affected side including musculature of the legs, arms, hands, face, and mouth. It can be impossible to stand, walk, get into a chair, bed or shower, put on clothing, or care for oneself independently with hemiparesis. Hemiplegia is paralysis on one side of the body, and is also commonly seen after a stroke. Hemiplegia is more severe than hemiparesis and will require more intensive physical therapy. It is very important to continue to try using the weak or paralyzed side of the body. Learned nonuse can occur when a person becomes dependent using the non-affected/stronger arm or leg, neglects to move or try to use the weaker arm or leg, and eventually causes movement of the limb to be much more difficult. Passive range of motion exercises can be instrumental in preventing the phenomenon of learned nonuse. Many times after a stroke, hemiparesis and hemiplegia can affect a person so much that an adaptive or assistive device becomes necessary to maintain adequate safety or is needed for overall well being. A cane, walker, orthotic device or splint are often used after a stroke as a compensatory or coping method for affected limbs. Physical therapists can help a person learn how to use these types of devices properly and safely, and can also teach the patient how to properly exercise with and without these kinds of devices. A PT can also educate a patient about which type of device is the least restrictive and most appropriate for current deficits, and how to make progress independently, so as not to become dependent on assistive devices. When a person has hemiplegia or hemiparesis, building back strength and confidence in standing, walking, or gait (manner of walking) is detrimental to making continuous progress. In physical therapy, a series of short term goals are organized to ensure measurable and achievable progress. These short term goals work towards building on small victories to eventually achieve an important long term goal such as standing alone or assisted for a certain amount of time, walking assisted or independently for a designated distance, or compensating for a problematic gait disturbance for a specific distance. As progress in physical therapy is made, the patient will feel more confident participating in a variety of tasks and hopefully achieve a level of independence with different tasks. Some people only experience mild hemiparesis after a stroke, and make progress quickly. However, balance and range of motion may not be the same as it was before the stroke. This can also be a safety hazard. Most research shows that falls are the number one medical complication after a stroke. Physical therapy is a vital way to improve balance, leg mobility, core strength, and learn to manage deficits in safe way. After a stroke, physical therapy can be the main method of recovery for achieving independence for functional tasks such as bathing, dressing, transferring into a bed or wheelchair, or even returning to work. Physical therapists help stroke survivors maintain strength, confidence, and safety!
