Causes, Features, And Effects Of Stroke On Neurological Rehabilitation: Implications For Nursing Essay.

Select a condition of interest which relates to your area of rehabilitation and Description construct an essay which addresses the causes, presenting features, and effects of the condition on the individual. Identify the anatomical and physiological relevance of the condition, noting the changes to structure and function as a result of the disease process, and highlighting the implications of these functional changes for rehabilitation nursing practice.

This essay should relate to the chosen condition but should not be specific to an individual patient. You do not need to provide a description of specific nursing interventions; rather the focus should be on the condition itself.

Condition of interest chosen: Stroke

Area of rehabilitation: Neurology

According to the World Health Organisation (2019), a stroke or cerebrovascular accident is caused by sudden interruption of the blood supply in the brain due to damage caused by blood vessel burst or presence of clot inside the blood vessels. This cuts off the supply of the nutrients and oxygen in the brain leading to the damage in the brain tissue. As per the statistics reported by the Australian Institute of Health and Welfare (AIHW) (2016) in 2012, it is estimated that 377,000 people of Australia (2% of Australians) had a stroke at some point in their lives. Of them 71% were aged above 65 years. However, there are certain positive aspects of the data as well AIHW reports that though the prevalence of stroke has remained the same since 1998, the disability and neurological complications arising from stroke have decreases from 45% to 39% during the tenure of 1998 to 2012. During the tenure of 2013-14, there are 28000 hospitalisations for rehabilitation care for strokes with average length of stay is 8 to 14 days (AIHW 2016). The following essay aims to analyse the importance and the implication of the rehabilitation nursing practice under neurological domain of the stroke patients.

According to the National Institute of Neurological Disorders and Stroke [NINDS], (2019), there are several risk factors that are associated with stroke however, majority of them are modifiable risk factors like high blood pressure, physical inactivity, obesity, high level of blood cholesterol, abdominal obesity and smoking of tobacco. Bridgwood et al. (2018) stated that hypertension increases the vulnerability of developing stroke after the age of 65. Cigarette smoking increase the vulnerability of developing ischemic stroke and hemorrhagic stroke and is linked with the development of the fatty substances in the carotid arteries or neck arteries (arthrosclerosis) that supply blood to the brain. Blockage of these arteries leads to stroke. Hypercholesterolemia also leads to the development of arthrosclerosis leading to stroke. Lifestyle changes can help to work on the modifiable risk factors of stroke. Diabetes, a fatal non-communicable disease or lifestyle disease also increases the chance of developing stroke during the later stages of life by increase the deposition of the cholesterol in the arteries (artherosclerosis) leading to the stroke (Arboix 2015). The non-modifiable risk factors of stroke include rage, gender, and race, family history of stroke or cardiovascular problems. Common cardiovascular problems that lead to stroke include coronary artery disease, irregular heartbeats (atrial fibrillation), valve defects and enlargement of the one of the heart’s chamber leading to formation of clots (NINDS 2019).

Risk Factors for Stroke

The main presenting features of stroke include sudden numbness or weakness in arm, face or leg of one side of the body, mainly left side and sudden confusion or trouble in communication or understanding speech. Some people experience trouble in vision, walking or loss of balance of the body along with head-ache. Other danger signs care characterised with double vision, vomiting nausea. The majority of these signs appear for a few moments and then disappear; these brief transitions are popularly known as “mini-strokes” or transient ischemic attacks (NINDS 2019).

Sullivan et al. (2013) stated that numerous conditions surface after stroke. Majority of them are common and improve during the course of time and rehabilitation. It is required to remain aware about the common effect of stroke in order to promote a comprehensive disease recover. The physical outcome of stroke includes weakness, numbness and stiffness. Moore et al. (2013) highlighted that the physical outcome of stroke is associated with the main location of obstruction and the extent at which the brain is affected. Since one side of the brain controls the other side, stroke at one side of the brain results in the development of the neurological complications on the opposite side of the brain. Stroke in the left side of the brain leads to the development of paralysis in the right side, along with the development of speech or language problem, problem in the behavioural style and loss of memory. Stroke in the right side of the brain, leads paralysis in the left side of the body (Nam et al. 2014). Other neurological complications of stroke include dysphagia or difficulty in swallowing, foot drop or difficulty in lifting or stepping with the front part of the foot leading to dragging of the toes (Rofes, Vilardell & Clavé 2013). Neurological complications are also reflected in the domain of muscle weakness known as hemiparesis and incontinence or inability to control and regulate the bladder movements. Stroke in the older adults causes seizures or epilepsy along with spasticity leading to painful muscle spasms. This is associated with vision problem, inquisitive or quick behavioural style plus loss of memory (Rofes, Vilardell & Clavé 2013). The aftermath of stroke hampers a person emotionally along with causing imbalance in the cognitive skills. The emotional impact includes development of persistent depression and uncontrolled emotions (Pseudobulbar Affect – PBA). Under cognitive skills, stroke survivors experience vascular dementia and aphasia (difficulty in expressing thoughts during speech) (Jeon et al. 2014).

Presenting Features of Stroke

Several aspects of the physiology like the blood pressure, temperature of the body, blood glucose level and oxygen saturation of the body gets hampered after ischemic stroke and intracerebral haemorrhage (Hall 2015). Mainly the temperature of the body along with blood pressure rise drastically after cerebrovascular accident before returning back to normal. The increase in the blood pressure leads to thickening of the walls of the small arterioles leading to the brain capillaries. These arterioles remain constricted in the majority of the time in order to prevent the transmission of the high pressure inside the capillaries. However, constant pressure created over these small arterioles leads to bursting of these arteries of the brain leading to the development of stroke. Burst of the arteries and vessels of the brain causes development of haemorrhage in the local brain tissue and thereby further compromising the function of the brain (Hall 2015). One of the most common types of the stroke blockage occurs in the middle cerebral artery that supplies blood in the middle portion of the brain’s hemisphere. When the middle cerebral artery is blocked on the left side of the brain, the person is more likely to experiences symptoms of dementia due to the loss of function in the Wernicke’s speech comprehension area located in the left side of the cerebral hemisphere of the brain. As a consequence of this, Broca’s motor area of the brain that functions in formation of words is hampered resulting in communication problem. Moreover haemorrhage in the brain leads to the loss of function of the neural motor control areas located in the left hemisphere of the brain. This leads to the generation of the spastic paralysis in the muscle contraction located in the right side of the body (Vaz, Raj & Anura 2014). Similarly, the blockage in the posterior cerebral artery leads to the infarction in the occipital pole of the hemisphere on the same side of the haemorrhage and this leads to loss of vision in both the eyes, mainly affecting half of the retina. The outcomes of strokes are more detrimental when there occurs hamper in the supply of the blood in the mid region of the brain leading to the blockage of the major biochemical signalling occurring in between brain and the spinal cord and thereby leading to the generation of both motor and sensory abnormalities (Vaz, Raj & Anura 2014).

Though blood glucose level along with the level of the oxygen saturation remains normal among the individuals during stroke, however, these parameters are nor stable and variers after the occurrence of stroke (Khonsary 2017).

Effects of Stroke on Anatomy and Physiology

According to Lynch, Hillier and Cadilhac (2014) commencing the rehabilitation early, within post 24 hours of stroke help to provide better functional outcomes. However, Lynch et al. (2015) highlighted in their retrospective study in the Australian healthcare system, nearly one third of the adults who have recently suffered stroke is not assessed for the rehabilitation. Moreover, when they are assessed, in the majority of the times, rehabilitations are not consistent for the patients with the stroke related symptoms. The study recommended increasing in the likelihood of the patients being assessed for the rehabilitation.  

In order to improve the neurological logical complications like hemiparesis and foot drop, mild to moderate physical exercise training in the rehabilitation centre might prove to be helpful. Regular practice of the mild to moderate physical activity training helps to improve the functional capacity, the ability to perform the daily living activities, decreasing the risk of subsequent events of cardiovascular complications and improving the overall quality of life. The physical exercises, which are recommended for the stroke survivors include aerobic exercise and strength based training (Billinger et al. 2014). Physical activity must also include motor-skill exercises in order to promote muscle coordination and strength and thereby helping to improve hemiparesis. Mobility training includes stability and strengthening of the ankle brace and thereby helping to recover from foot drop. Constraint-induced therapy or forced-use therapy deals with restraining of the unaffected limb and moving the affected limbs and thus helping to promote muscle coordination and strength. Range of motion therapy is used to ease the muscle tension or spasticity and thereby helping to regain the motion. Range of motion therapy in the face muscles help to ease the communication defects (Saunders et al. 2016). However, Billinger et al. (2014) emphasised that the goals of the physical activity must be customised as per the exercise prescription of the stroke survivors in order to promote long-term adherence.

Robotic technology, which is of the robotic devises in order to assist the impaired limbs for performing repetitive motions is found to be effective in promoting strength and function of the limbs. Further research is undertaken in order to promote the development of the easily transportable and wearable devises in order to improve the process of rehabilitation while the patient is discharged at home (Pol et al. 2013).

Turner-Stokes et al. (2015) recommended that in order to customize the rehabilitation program for the stroke survivor patients, one of the concerns that must be taken under the active consideration is patient engagement. In order to increase the patient’s participation, it is the duty of the rehabilitation nurse to execute effective communication for the development of therapeutic relationship with the patients. The development of therapeutic relationship helps in the formation trust and thereby helping the nursing professional to highlight the clinical priority and thereby designing the rehabilitation program accordingly (MRCNA & Smith 2002). Pryor and Buzio (2010) stated that carefully and collaboratively designed rehabilitation programs help to improve the overall outcome of care.

Physiological Changes after Stroke

Brady et al. (2016) proposed in favor of the speech and language therapy for the people with aphasia following stroke. The therapy is found to promote improved level of the functional communication, along with reading and writing. Lim et al. (2016) neurologic music therapy (NMT) along with speech language therapy helps in the improvement of the aphasia quotient (AQ) among the post-stroke patient. Moreover, NMT improves cognitive, sensor and impaired motor functions through stimulation of music.

Conclusion

Thus from the above discussion, it can be concluded that post-stroke patients suffer from the several neurological, cognitive and behavioural complications resulting out of the haemorrhage of the brain due to blood clot. In order to improve the quality of life of the individuals with stroke, rehabilitation programs are highly recommended. The main rehabilitation interventions include training of the physical exercise for improving the muscle stiffness and muscle coordination. Other interventions include speech and language therapy and neurological music therapy in order to improve the speech defects of the communication problems. However, the interventions or the rehabilitation program must be designed with a patient centred approach by promoting patient engagement in order to improve the overall outcome of care.
