Vibratory Therapy for Patients With Chronic Low Back Pain
Recruitment status was: Recruiting
The lumbar spine is currently one of the most affected areas by nociceptive processes , referred back pain, which can be provided from a herniated intervertebral disc . Such conditions are considered a public health problem , since considerably affect the population , mainly young adults , which may lead to functional disability and absenteeism . Soon , his treatment involves high costs and rehabilitation time indefinite , generating great scientific interest focused on the search for new techniques that can provide an acceleration of functional recovery of these individuals .
Thus , the establishment of evaluation protocols that provide quantitative data concerning the functional capacity is of utmost importance . From the electromyographic analysis , one can measure the electrical activity of muscle and identify abnormal patterns of response. For the identification of kinematic changes becomes useful equipment capable of recording the speed and angle of movement, as the accelerometer . Another evaluation method applicable to cases of herniated disc and back pain is the force platform to quantify the ground reaction force during the stance phase of the movement . Also , the quality of life should be taken into account as routinely observed psychological impairment involving issues related to vitality, emotional and social aspects , which can be identified through the questionnaire of quality of life ( SF -36 ) .
With regard to physical therapy intervention , we seek to use resources to compose promising treatment program along with conventionalexercises. A novel therapy in the treatment of back pain is the whole body vibration , as it promotes increased range of muscle spindles via increasing the tonic vibration reflex and consequently improving the mechanism of involuntary muscle control . Thus , the association between an accurate assessment , exercises and therapy vibratory seeks early rehabilitate individuals affected by back pain or herniated disc , delaying or even avoiding surgery .

- Electromyographic analysis of the trunk erector of patients with chronic low back pain . [ Time Frame: Thirty seconds. ]
All groups performed the evaluation of muscle electrical activity , using a surface electromyography , 2 channels ( EMG System ® ) , model EMG 230C - USB , composed of an analog-digital converter 12-bit resolution and power supply to battery to avoid interference from the power grid . The parameters used were : sampling frequency of 2,000 Hz , unit uV , -2000 Xmin , Ymax 2000 Coef . The 0 and Coef . B 500.
The electrodes were then fixed in pairs , respecting the distance of 2 cm between them ; longitudinally over the belly of the erector muscles of the trunk . Data were collected in the prone and standing for 30 seconds , during which the subject performed the isotonic contraction muscle evaluated .
- Analysis of pain using a visual analogue scale . [ Time Frame: Two days. ]The subjects were instructed to respond to a visual analogue scale with the level 0 as no pain and 10 as state level of maximum pain .
- Force Platform [ Time Frame: Thirty seconds ]The acquisition of data on the force platform lasted 30 seconds , during which patients took the standing position in the region previously marked on the equipment , so that the support base was identical for all volunteers . Also , samples were collected at rest , followed by consecutive flexion-extension of the trunk .

This group will consist of 20 individuals, 10 with lumbar disc herniation and 10 with chronic low back pain who underwent treatment with exerxises.
The individuals who make up this group performed exercises for 10 consecutive sessions.
