Effects of Different Kinds of Exercise in Low Back Pain

Biering-Sorensen maneuver.Participants will be in a prone position with the anterosuperior iliac spines on the edge of a stretcher. Their lower body will be strapped by the ankles and hips, with the upper body suspended. Participants will keep their trunk extended and parallel to the ground for 60 seconds.

After adjusting height, pedals and backrest in a cycloergometer, there will be 20 minutes of cycling, of which 5 minutes will be a warm-up at 50-60% of maximum heart rate and 15 minutes at 60-70% of maximum heart rate. There will be a constant monitoring of heart rate and oxygen saturation.

A maneuver equivalent to Biering-Sorensen test, but with upper limb support on a level step and electromyographic monitoring to ensure minimal activation of the erector spinae. It will be explained to the participant that the aim of such an intervention is to cause electromyographic silence of the erector spinae and keep it for 1 minute.
