About

The prevalence of low back pain is approximately 49% to 90%, and that 25% of patients seeking treatment for low back pain have a recurrence within the first year. Chronic non-specific low back pain is the most common of all types of pain, not being attributed to a specific pathological cause and with a minimum pain duration of 12 weeks. Forty percent of subjects with acute low back pain will develop chronic low back pain.

Exercise is recommended for the treatment of chronic low back pain because of significant improvements in pain and disability over other therapies, but the evidence is low in the treatment of subacute or acute pain, as exercise appears to be equally effective over rest. Motor control is based on the contraction of the deep and stabilising muscles of the lumbar spine (multifidus and transverse abdominis), performing simple voluntary contraction exercises and increasing (without losing this contraction) their difficulty and functionality. At the beginning, the patient must be able to maintain the isometric contraction of the deep muscles while breathing normally. On the other hand, there is great difficulty in voluntarily contracting the multifidus muscles, especially for subjects with chronic non-specific low back pain, where arthrogenic inhibition hinders their contraction. The application of ultrasound as feedback may help patients to correctly contract this musculature.

Our main objective in the study will be to measure and compare pain, disability, global impression of effect, in patients with non-specific mechanical chronic low back pain after applying a motor control exercise programme with and without ultrasound feedback.

In addition, the investigators will compared this type of exercise with a conventional exercise programme.

Full description

A study will be carried out to compare a conventional exercise protocol for the management of non-specific chronic low back pain, with another motor control exercise protocol with and without ultrasound feedback for its correct learning and execution.

For the ultrasound feedback, a video will be recorded where the participant will be able to see how the core muscles contract when each of the motor control exercises is performed.

The participants will be divided into three groups. The first group will perform a general exercise plan for the lower back. The second group will perform a plan of specific motor control exercises aimed at activating the lumbar multifidus and transversus abdominis muscles, and the third group will perform a plan of specific motor control exercises aimed at activating the lumbar multifidus and transversus abdominis muscles using ultrasound as a feedback method.
