Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
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
Secondary Outcomes (1)

Low intensity laser
EXPERIMENTALSo that this research recrutarou 30 subjects with spastic hemiparesis sequel, post stroke who have gone through three phases, with three evaluations. If this conformation is necessary, therefore, it is a search for intergroup analysis, and the values found in Phase I were faced with the values found in Phases II and III. The phases comprise: * Phase I (1st Cycle): Individuals treated with LLLT not only performed the evaluation of muscle activity, torque and lactic acid level. * Phase II (2nd Cycle): Individuals undergoing the application of LLLT, with the same off, and assessment of muscle activity, torque and lactic acid level. * Phase III (3rd Cycle): Individuals undergoing the application of LILT and evaluation of muscle activity, torque and lactic acid level.
Interventions
The study wants to evaluate the use of low intensity laser on the spastic muscle. Want to assess whether the Low level laser prove change in muscle performace of the individual but also alters muscle activity and blood lactate.
