Physiotherapy Re-education of Pre-activation of the Transverse Abdominis in Patients With Chronic Low Back Pain

Hypothesis: The hypothesis of the study is that the physiotherapeutic re-education of the pre-activation of the transverse abdominal muscle decreases pain intensity in patients with chronic non-specific low-back pain by at least 30% and is more effective than conventional treatment. Aims: the principal aim is to determine the effectiveness of a physiotherapeutic re-education program based on the pre-activation of the transverse abdominal muscle on pain intensity in adult patients diagnosed with chronic non-specific low-back pain compared to conventional treatment in a primary care setting. The secondary aims of the study are to assess the effects of a physiotherapeutic re-education program based on the pre-activation of the transverse abdominal muscle on: (1) disability and limitations for the development of the activities of daily living associated with LBP, (2) transverse abdominal muscle muscle contraction, (3) to assess whether the resistance training parameters applied to older adults are valid for young adults and (4) to determine whether the training protocols used for the cervical spine could be extrapolated to the lumbar spine.
