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.

| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Other | blood lactate | The collection of blood lactate happen with the aid of lactomer , portable device brand (Accutrend ® PLUS Roche). Will be collected before and after the completion of the exercise isometric contraction, a drop of blood to detect the level of lactate in the blood. So to differentiate the amount found in the blood before and after exercise and to see whether the application of Laser alter this concentration in the blood. | three days | No |
| Primary | muscle activity | Muscle activity will be captured with the aid of electromyography. So that the EMG data will be collected with the completion of the isometric contraction of the rectus femoris, vastus. Being held in this capture period of 50 seconds. | three days | Yes |
| Secondary | muscular performance | The muscular performance will be analyzed with the equipment isokinetic dynamometer. Volunteers will be placed in a sitting position in the chair equipment (Biodex System ®), with the limb to be assessed on the supported equipment support. Thus the device is triggered mode isometric contraction and the individual remained in contraction for a time of 50 seconds. Patients will be advised to carry their maximum contraction so as to obtain the torque of the muscles. |
