Ischemic Brain Clinical Trial
Official title:
Immediate Effect of Low Intensity Laser on the Spastic Muscle Fatigued.
The poor eating habits and sedentary lifestyle of young people can reflect on structural
changes in adult life, leading to vascular brain diseases. The cerebrovascular accident
(AVC) represents the second cause of death throughout the country. Presents rapid
development of clinical signs, providing focal disorders or brain function. It is necessary
to the knowledge and development of new treatment techniques that may minimize the sequelae
caused by the AVC, which is a common disease and of great impact on public health,
represents the main cause of adult neurological disability, affecting the basic functions of
the limbs, motor control and balance, strength and mobility, which involves changes in daily
life and low self-esteemIn addition to the high cost of treatment and in the long run.
Thus, this study aims to analyze the response of low intensity laser on the prevention of
pain and fatigue induced in rectus femoris, vastus of patients with sequelae of spasticity
associated with effects on the laser promotes on muscle performance and muscle activity.
It is believed that this study get positive results as regards the increase of time
antecedent to muscular fatigue associated with the skeletal muscle performance, so that the
normotonics muscles gain strength and overcome the resistance of hypertonic muscles. In this
way, it is expected that after the application of low intensity Laser Therapy (LILT) occurs
to the adequacy of spasticity, muscle function the gain that had provided the highest
quality of physiotherapy care.
It is known that treatment with the laser on the skeletal musculature, presents positive
results and on the peak torque, by means of the skeletal muscle performance and consequently
gain increase muscle performance (LEAL JUNIOR et al, 2010; ALMEIDA et al, 2011).
Armed with this information you can infer that the low intensity laser therapy on the
spastic muscle, would result in improving muscle performance, with an increase of
pre-stressing, improving the functional capacity of individuals under the exercises imposed
by physical therapy. In this way, the sessions will take more satisfactory results which
jointly provided better quality of life for these patients.
With the course of the years, became notorious the transformation in the epidemiological
profile of the Brazilian population, with the progressive decline of infectious diseases and
illness narratives and the gradual growth of the chronic degenerative diseases, particularly
cardiovascular diseases of (ARAÚJO, 2012)
According to statistics of the Ministry of health, in the year 2010 were recorded about 100
thousand deaths due to cerebrovascular accident (AVE), a result of the sudden interruption
of blood flow of the brain, which is currently responsible for leading cause death in Brazil
(MINISTRY of health, 2012).
The heterogeneity of the Brazilian population, would explain the current epidemiological
transition, and as a result the high rates of mortality. The diseases of the circulatory
system are as main cause death of Brazil, emphasizing the cerebrovascular disease,
responsible for one third of deaths in the country.
The cerebral arteries are responsible for giving the necessary nutrients as a source of
energy to neurons, the brain requires intense blood flow to meet your high intake of
nutrients. Being that the interruption of the flow of oxygen and glucose for a period in
excess of five minutes can cause irreversible damage to the brain.
Several pathological processes can cause the interruption of blood flow in certain brain
areas. Between these processes include hemorrhages, embolisms, stroke and diseases that lead
to suspension of blood flow, and therefore the deficit in the supply of nutrients.
The blood deficit promotes changes in cellular metabolism, which can lead to injury and/or
death of brain tissue. According to estimates, 80% of the incidence of BIRD arteriolar
occlusion resulting from atheroma plates or secondary brain artery emboli that deprive the
brain of blood supply.
The likelihood of the AVE doubles every decade of life, from 55 years of age. Although
leverage the ranking of deaths in the country, statistics from the Ministry of health in
2010, showed decreased mortality rate in the age group up to 70 years, representing an
annual average reduction of 3.2% (MINISTRY of health, 2012).
As established earlier, the differences in the prevalence of risk factors among the
population due to high heterogeneity, that is, different customs, habits and lifestyles. So
in that, poor eating habits and physical youth population may reflect structural changes in
adulthood, and may lead to vascular brain diseases. Among the risk factors associated with
the AVE is hypertension, dyslipidemias, diabetes, smoking, alcoholism.
In general the clinical picture presents itself with motor and sensory changes, that may be
associated with deficits in cognitive and perceptual functions by damaging both physical and
physiological functions of the patient (DIETZ; SINKJAER, 2007). Due to the AVE be associated
with motor disability tables, resulting in physical limitations, mainly resulting from
spasticity, is necessary to search for ways to minimise this damage. In this way, it is
believed that with the help of biomedical instrumentation, which in addition to providing
quantitative and reliable data on the functional capacity of the individual, allows the
development and recruitment of equipment to help in the evaluation of the General State of
the patient and so consequently best results before the practice of neurological
rehabilitation. Therefore it is of utmost importance to biomedical resource utilization as
surface electromyography that refers to a method of non-invasive monitoring, providing
values for the square root of the mean squared Value (RMS - R Englishoot Mean Square),
demonstrating this parameter the results of signal amplitude through the average power in
the time interval analyzed, containing information about the amount of traction units fired
at any given movement
Isokinetic dynamometry bound that provides resistance to joint movement over a given range,
enabling the analysis of muscle force-related parameters such as torque, power, and
endurance. These two features combined will contribute to the determination of the time when
the o muscle spastics had to fatigue muscles. On this information, the sessions can be
reworded to the concrete limitations of patients and consequently the improvement of
rehabilitation, which will automatically improves the quality of life of these individuals.
