SUMMARY:

Introduction: Low back pain is one of the most disabling conditions, with high socioeconomic costs and negative impacts on quality of life, affecting up to 90% of the adult population at some point in their lives. It has been proposed that changes in motor and postural control and decreased lumbar stability are related to the development of the condition, where respiratory muscles are closely linked, so that individuals with low back pain are more prone to decreased thickness, weakness and fatigue of the diaphragm compared to healthy individuals. In this sense, there is evidence that Inspiratory Muscle Training (IMT) is capable of improving the activation and thickness of the stabilizing muscles of the spine in low back pain, reducing pain intensity and improving respiratory muscle strength and quality of life in different populations. Objective: To evaluate whether high-intensity IMT is effective in reducing pain intensity in individuals with chronic nonspecific low back pain and muscle weakness. Methodology: This is a randomized, double-blind clinical trial that will consist of two groups of individuals with chronic nonspecific low back pain, an experimental group (EG) and a control group (CG). The sample will consist of individuals of both sexes, aged between 18 and 59 years, Body Mass Index (BMI) <30 kg/m2, pain intensity between 3 and 8 on the Numerical Pain Scale (NPS), duration of symptoms >3 months and weakness of inspiratory muscles. Those who do not complete the protocol in its entirety, with 03 consecutive absences and are incapable of understanding and/or performing the data collection procedures or refuse to sign the ICF and present hemodynamic alteration of an abrupt increase in SBP >25 mmHg during the IMT will be excluded. Both groups will undergo an IMT protocol with the POWERbreathe® Classic MR device, twice a day, for 8 weeks, in each of which 5 sets of 10 repetitions will be performed. The EG will undergo high-intensity IMT (80% of MIP) and the CG will perform low-intensity IMT (10% of MIP). The workload may be adjusted weekly by a supervisor, if necessary. The primary outcome assessed will be pain intensity by NPS and the secondary outcomes will be the level of functionality, lumbar mobility, range of motion and strength of trunk muscles, respiratory muscle strength, ventilatory capacity, disability related to low back pain and quality of life. Expected Results: The present study is expected to identify a clinically significant reduction in pain intensity, lower level of disability and improvement in the quality of life of subjects with chronic nonspecific low back pain undergoing high-intensity IMT.
