The main objective of this randomized controlled trial is to investigate the efficacy of a 6-week therapeutic exercise program, performed with virtual reality (VR) manipulating visual proprioceptive information during all lumbar movements in the different therapeutic exercises (experimental group), on pain and disability, kinesiophobia, range of motion (ROM), catastrophizing, quality of life, and physical fitness in patients with chronic non-specific low back pain compared to the same therapeutic exercise program without VR (control group).
Chronic pain is considered an urgent global public health problem. One of the most prevalent chronic pain pathologies worldwide is low back pain (LBP). Kinesophobia (fear of movement) has been largely associated with pain intensity, disability, worse quality of life and chronification in LBP; while physical reconditioning has been proposed in clinical practice as a key element in the treatment of LBP.(20-22) However, the efficacy of physical reconditioning programs developed so far would require considerable improvement. The induction of illusions in virtual reality (VR) through visual cues could be a valid alternative to evoke motion illusions and be able to modify proprioceptive integration, acting on kinesiophobia, in turn. The main objective of this randomized controlled trial is to investigate the efficacy of a 6-week therapeutic exercise program, performed with VR manipulating visual proprioceptive information during all lumbar movements in the different therapeutic exercises (experimental group), on pain and disability, kinesiophobia, range of motion (ROM), catastrophizing, quality of life, and physical fitness in patients with chronic non-specific low back pain compared to the same therapeutic exercise program without VR (control group).

The VR therapeutic exercise program will be implemented for 6 weeks at a frequency of 2 sessions per week with the aim of improving pain and disability, kinesiophobia, range of motion (ROM), catastrophizing, quality of life, and physical fitness. This group will perform the 8 VR exercises of "Back School" by manipulating visual proprioceptive information during all lumbar movements. They will be performed in 2 sets whose intensity and repetitions will be configured and individualized by a self-reported rating of perceived exertion (RPE) through the Borg 6-20 scale. The appropriate training intensity is established with an RPE score between 13 and 17; for this reason, the first 2 weeks will work at an RPE of 14, the 3rd and 4th weeks at an RPE of 15; and finally, the last 2 weeks will work at an RPE of 16. The first 3 weeks will work without additional load, and the last 3 weeks will work with weights, increasing their weekly load individually.

Low back pain
Measured with a Visual Analogue Scale (0-10 points). Higher scores mean a worse pain.
Time frame: At six weeks
Range of movement
Measured with an electrogoniometer
Time frame: At six weeks
Disability
Measured with the Roland Morris Questionnaire (0-24 points). Higher scores mean a worse disability.
Time frame: At six weeks
Physical activity
Measured with the International Physical Activity Questionnaire (short-form). This is a 7-item scale used to assess physical activity. Results are divided into different activity levels (low or inactive, moderate, and high activity), and scores are obtained by multiplying the duration of physical activity by the intensity of a task that is metabolically equivalent for each activity level in the last 7 days.
Time frame: At six weeks
The Quality of life
Measured with the Euro Quality of life five dimensions with five levels questionnaire (-0.59 to 1.0). Higher scores mean a better quality of life.
Time frame: At six weeks
Kinesophobia
Measured with the Fear Avoidance Beliefs Questionnaire
Time frame: At six weeks
Catastrophizing
Measured with the Pain Catastrophizing Scale (0-52 points). Higher scores indicate higher levels of fear-avoidance beliefs.
Time frame: At six weeks

Physical capacity
Measured with the Sit-to-Stand 60 test. The STS-60 measures the number of times an individual can sit and stand up from a chair in 60 seconds. Higher number of repetitions indicate higher physical capacity.
Time frame: At six weeks
