Item Avaliação do uso de sensor de contração muscular no treino sensório-motor em indivíduos com dor lombar persistente(Universidade Brasil, 2020) Bonfim, Rafael Victor Ferreira do; Almeida, Vilson Rosa de; Garcia, Lívia AssisLow back pain is a chronic health problem, with a high socioeconomic impact, due to its high prevalence; it corresponds to any pain felt in the lower back. It is also an expensive health problem, both on personal and social level. The deficiency in the mechanical stability of the lumbar spine is known to decrease spinal muscle activation and could result in the occurrence of pain symptoms in the lower back. The stabilizing musculature is activated to protect the spine during body movements; however, its training could be carried out through specific exercises. Sensor technology could facilitate this task, being implemented, for example, in applications such as monitoring the effectiveness of home rehabilitation interventions in individuals with low back pain. The aim of the present study is to analyze the effect of stabilizer muscle training using a contraction sensor in individuals with nonspecific persistent low back pain, by assessing pain, balance, plantar pressure, muscle isometric resistance test and muscle ultrasound thickness. The sample consisted of 30 individuals with chronic low back pain, aged between 18 and 45 years. In the present horizontal, double-blind, study, in which each individual was evaluated before and after the intervention with 16 visits of 30 minutes each, performed on alternate days, using the muscle contraction sensor for the abdominal muscles. Numerical pain scale, baropodometry, stabilometry, Biering Sorensen muscle isometric resistance test and examination of the ultrasound thickness of the transverse abdomen were used for assessment. As a result of the research, a reduction in pain levels was observed, as well as an improvement in plantar distribution and balance. The resistance of the multifidus and the thickness of the transversus abdominis increased with training employing the contraction sensor. It is concluded that the portable system, developed with low cost, could help in the control of the stabilizing muscle contraction exercises, improving its contraction capacity and motor control and, consequently, improving balance and reducing low back pain, which could cause a major socioeconomic impact.Item Ozonioterapia associada a um programa de exercício na dor e incapacidade de indivíduos com dor lombar crônica: ensaio clínico controlado e randomizado(Universidade Brasil, 2022) Silva, Rafael Basatos; Garcia, Lívia Assis; Tim, Carla RobertaChronic low back pain (CLBP) is one of the most common musculoskeletal disorders, prevalent worldwide and one of the main causes of disability and damage to quality of life, representing a significant economic burden. Ozone therapy (OT) has been suggested in clinical practice as an adjuvant therapy to physical exercise, however the evidence is limited for its recommendation. Thus, the aim of this study was to evaluate the effects of OT in combination with a physical exercise protocol on pain level in subjects with chronic low back pain. Forty-two volunteers were randomized into 2 groups: Control group (Ex): volunteers underwent a physical exercise protocol; Ozone Therapy Exercise Group (ExOT): volunteers underwent a resistance physical exercise protocol associated with OT. Interventions were performed twice a week for a period of 6 weeks, totaling 12 sessions. The exercise program consisted of exercises that strengthened, stretched, mobilized, coordinated and stabilized the abdominal, lumbar, pelvic and lower limb muscles. OT was applied at 5 points on the paravertebral muscles, bilaterally, totaling 10 points, through the intramuscular technique at a concentration of 20 g/ml and with a volume of 2 mL of ozone right after each proposed exercise session. For assessment and reassessment, the Numerical Pain Scale (END) was applied; disability index (Oswestry Disability Index); flexibility test (Third finger to floor test); trunk flexion/extension mobility test (Gonimetry); kinesiophobia (Kinesiophobia Cap Scale); emotional state (Anxiety Numerical Scale - ENA) and assessment of the perception of the global effect (Global Effect Perception Scale - EPEG). The results showed that both the Ex and the ExOT groups had a lower pain level, lower scores in disability tests, improved flexibility, lower scores in kinesiophobia when compared to the initial values. However, the lowest scores for the level of pain, disability and the highest scores for the level of perception of recovery were evidenced in the ExOT group. Thus, it can be suggested that OT associated with the physical exercise program was a more effective method in reducing pain and functional disability in the treatment of CLBP.
