1. Introduction to Intervention
Strokes are known as the leading cause of acquired disability in adults where between 20-30% are left unable to walk, and leaving those who are able to walk, with a moderate to severe walking disability (Maguire et al., 2012). This disability results in a huge socioeconomic impact on the patients and their families lives. In order to improve their quality of life, an improvement in balance is the important first step in which is crucial to enable more independent movement, for example walking.
A stroke can be brought on by many different factors like age, gender and family history – all of which one cannot control. Others are lifestyle factors like high blood pressure, high cholesterol, smoking, obesity or being over weight, poor diet, lack of exercise and drinking too much alcohol (stroke foundation Australia). Currently there is no universally accepted treatment (Ward, 2005).
There is evidence to suggest that improved motor recovery occurs when the brain uses the original neural system to control the movement as this is shown to represent "true" recovery. Whereas, if new networks were to form in the unaffected hemisphere of the brain, motor recovery will be reduced. As a result of using these new networks, fine motor control is lost and employment of compensatory movement strategies are associated with a poorer functional outcome (Nudo, 2007). The recovery of motor skills following a stroke, like walking, relies on the brain’s ability
The most common causes of strokes are thrombosis. This is when a clot forms in one of the arteries, mostly in the carotid in the neck and the vertebral artery. The blood is thick and moves very slowly through the artery. The thrombus will form on the damaged area of the artery wall and will cut off the flow of blood to the brain. The area of the artery that is damaged is cause by arteriosclerosis. This form of
Most exercise is designed for neurorehabilitation, not cardiovascular health, so there is a very different definition for stroke patient exercise, as well as a very different goal set. Because strokes affect each person differently, treatment is also specific to the individual. The literature included in this review focuses on three different methods of exercise, each with very specific goals in mind. Cabanas-Valdés and collegues study was on Core and Trunk stability, Minyoung describes use of Virtual Reality enhanced exercise for treatment, and Tutak introduces the concepts behind Rehabilitation
Strokes are the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For African Americans, stoke is the 3rd leading cause of death.(http://www.cdc.gov/stroke/facts.htm) It is estimated that About 795,000 people have a stroke each year; about one every 40 seconds - there are many medical conditions that can cause a stroke and it is estimated that 8 out of 10 strokes can be prevented. However, there are some things that cannot be controlled when you are predisposed to
The risk factors for stroke can be classified into non-modifiable and modifiable. Non-modifiable risk factors include age, family history, prior stroke, gender, and race. Whereas modifiable risk factors are hypertension, diabetes mellitus, coronary artery disease, atrial fibrillation, dyslipidemia, cigarette smoking, obesity, valvular heart disease, alcohol abuse, and physical inactivity (Basharat et al., 2012).
Strokes are the fifth leading cause of deaths in America. They are also one of the leading causes of disabilities in adults. There are many factors, such as atrial fibrillation and lifestyle factors, which could lead to a potential stroke. There is the atrial fibrillation (shortened to “AFib”) and stroke connection. AFib is the constant and irregular beating of the two atria valves of the heart. The irregular heartbeats can cause blood to form clots in the heart and travel towards the brain. There are other types of risk factors that can lead to strokes, which are medical risk factors, lifestyle risk factors, and uncontrollable risk factors. Some examples of medical risk factors include high blood pressure, circulation problems, high cholesterol,
There are many ways someone can prevent a stroke and it is all about recognizing certain health issues and being as healthy as possible. Diet and exercise are one of the main ways a person can prevent a stroke, especially if they are overweight. Eating fatty foods can increase the amount of fat deposits in the body which can eventually lead to clotting. Being overweight tends to result in high blood pressure or diabetes which are both main causes of a stroke. Controlling your blood pressure, the type and amount of food you consume, and exercising can be very preventative from having a stroke. It is also important to know your risks. If you know people in your family have high blood pressure, have had blood clots, or any heart problems, it is
Stroke can be defined as an unexpected and evolving start of neurological symptoms due to a quick and steady blocking of blood stream to the brain. A stroke is a common brain injury that ranks amongst the leading causes of death around the world (Murray and Lopez et al 1997). The symptoms and the harshness of the injury is determined by the area, and the degree of damage it causes to the brain. A common result of a stroke is Hemiparesis, which effects only half of the body. This condition then adversely effects the different systems of the body causing weakness of the muscles and loss of agility. Following a stroke, many patients begin to experience a continuous sensorimotor shortage. This shortage in sensorimotor not only hinders their capacity
Stroke is the number one leading cause of adult disability, and it is estimated that approximately 7 million Americans are living with the effects of stroke. The direct and indirect cost of stroke in the United States was approximately $53.6 billion, with a mean lifetime cost estimated at $140,048 (American Heart Association, 2004) and each year, approximately 795,000 people have either a new or recurrent stroke (Go et al., 2013).
Stroke is one of the leading causes of death and long-term disability in the world. Every year, more than 795,000 people in the United States suffer a stroke. About 87% of all strokes are ischemic strokes, where blood flow to the brain is blocked and 13% are hemorrhagic strokes, where a weakened blood vessel in the brain ruptures. Stroke costs the United States an estimated $34 billion each year. Strokes are diagnosed and confirmed using physical examination, blood tests and brain imaging techniques. Clinical treatments and preventative measures for stroke have improved in the acute setting, but long-term rehabilitation techniques remain limited. Stroke is a major health problem that greatly affects people of all ages and causes long-term disability
Impairments can contribute to an increased risk of falls at all stages following a stroke.2,5 As a result of these impairments, stroke has been classified as the most disabling chronic disease, with about 80% of individuals falling within the first three months from loss of balance when walking.2,5 In addition, approximately 70% of individuals who have had a stroke experience ongoing difficulty with ambulation within the first year.2 One research study revealed that patients post stroke have fall rates that range from 3.8 to 22%, and the incidence of falls range from 1.3 to 6.5 times in the year after the stroke.1 Furthermore, stroke has been identified as the primary cause of disability in the United States and the third leading cause of death in people over the age of
Stroke is seen as a major health concern and this is due to the fact that every year, as many as 110,000 individuals suffers from strokes making it a key issue. (NHS 2014)
Stroke significantly affects thousands of individuals annually, leading to physical impairments and functional disability. Due to stroke the patient's gait pattern changes from normal walking speed, endurance, symmetry and stride length which leads to pathological gait pattern\cite{bortole2015h2}.\newline
Cerebral vascular accidents can create debilitating outcomes, with 50% of patients experiencing a decrease in function of the upper extremities (Mercier, Audet, Hebert, Rochette, & Dubois, p. 2606, 2001). Studies have shown that six months after a stroke, 30% to 66% of patient’s will remain with functional deficits in their upper extremities, while only 5% to 20% will regain full function (Kwakkel, Kollen, van der Grond & Prevo, p. 2181, 2003). To combat this dysfunction on the affected side, a variety of interventions and treatment options are currently used. This includes neurodevelopmental treatment, sensorimotor training, splinting, and repetitive task-specific techniques, however therapy often focuses on compensatory techniques using the
Cerebrovascular accident, also known as a stroke, is one of the top causes of death and disability amongst older adults. When any portion of the brain is denied blood flow, this causes a stroke. The severity varies, depending on the area and amount of blood denied. Some risk factors of a stroke include the following; Hypertension, age, previous lifestyle, diet, exercise patterns, your social status, and access to healthcare. Hypertension is the main risk factor because hypertension increases pressure, restricting blood flow. Symptoms of a stroke vary for each individual depending on what the stroke is caused by. Symptoms include sudden numbness/tingling/weakness
Every day, men and women suffer from a stroke, when the arteries that bring blood to the brain are clogged, essentially suffocating the brain. This then damages the brain, leaving the victim unable to walk or speak properly. Oftentimes, these stroke patients can become hemiparetic, meaning that part of their brain was damaged, and half of their body became disabled or unusable. However, neuroscientists and physical therapists have developed a way to train the gait of these hemiparetic stroke patients, allowing them to walk properly again, using Rhythmic Auditory Stimulation(Cha, 2013, Habib, 2009, McIntosh, 2010, Schneider, Suh, Thaut, 2010). As brain plasticity is damaged severely during stroke, therapists must consider increasing the plasticity of the brain using repetition, which RAS utilizes(Cesqui, 2017, Gloag, 1985, Habib, 2009, McIntosh, 2010,Särkämö, 2008, Schneider, 2010, Suh). Rhythmic Auditory Stimulation utilizes repetitive rhythms in order to develop specific connections between the auditory and motor functions (Cha, 2013, Habib, 2009, McIntosh, 2010, Schneider, Suh, Thaut, 2010). The direct links between the auditory and motor functions become critical in RAS, as the stimulation of the auditory functions directly benefit the motor areas of the brain throughout RAS, benefiting gait in hemiparetic stroke patients (Cha, 2013, Gloag, 1985,Habib, 2009, McIntosh, 2010, Morris, 2009, Särkämö, 2008, Schneider, 2010, Suh, Thaut, 2010).
