EFFECTS OF A PILATES METHOD EXERCISE PROGRAM ON BACK PAIN IN BRAZILIAN AIR FORCE HELICOPTER PILOTS: A RANDOMIZED CONTROLLED TRIAL
Electromyography, Rehabilitation, Exercise, Physical Therapy Specialty, Muscle Fatigue.
Background: Helicopter pilots tend to have chronic low back pain due to the exposure to vibration and the asymmetric posture adopted during flight. Objective: To analyze the effects of an exercise program, based on the Pilates Method, on low back pain and muscle fatigue in Brazilian Air Force (FAB) helicopter pilots. Methodology: This is a randomized clinical trial. The sample will be composed by pilots, helicopter instructors from FAB. All individuals will be assessed for pain sensation through the Numerical Pain Scale, disability associated with low back pain, using Roland Morris Disability Questionnaire, muscular resistance of the trunk extensors, through Ito test and electromyography activity of trunk extensor muscles. The pilots will be randomly assigned to Exercise Group (Pilates method exercise program, twice a week for 12 weeks) and Control Group (no intervention). After the sixth and 12th week of the intervention program, a new evaluation will be carried out, identical to the initial one. To descriptive statistics will be used measure of central tendency and dispersion. For analysis of data normality, the Kolmogorov-Smirnov test will be used and for homogeneity between groups at baseline the one-way ANOVA. For intra and intergroup comparisons a two-way ANOVA with repeated measures will be performed. In all tests, a significance level of 5% will be adopted. Expected results: It is expected to analyze the effects of Pilates method exercises on low back pain and muscle fatigue of the spinal erectors of FAB helicopter pilots, in order to support health professionals in preparation of specific physical training programs for this population.
