Changing Lower Back Pain Through Virtual Reality

Study Overview
=================
Brief Summary
-----------------
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).

Detailed Description
-----------------
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).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Physical Activity + Virtual Reality<br>A program of 8 VR exercises will be applied, of a therapeutic nature, based on the applied exercises of the Back School, aimed at gaining strength, stability, mobility and flexibility of the abdomino-lumbo-pelvic region and the lower extremities. For each exercise, the VR goggles will manipulate the visual proprioceptive information by modifying the perceived degree of lumbar flexion and extension, i.e., in the VR goggles they will perceive that your movements are different from what you are actually doing. | Other: PHYSICAL ACTIVITY + VIRTUAL REALITY<br>* 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.<br>|
| Active Comparator: Physical Activity<br>The same therapeutic exercise program will be applied as the experimental group, but without VR. The training methodology and progression of loads, evaluations and supervision by the physiotherapist will also be the same. | Other: PHYSICAL ACTIVITY<br>* The 8 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 exercises of Back School without VR. 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Low back pain | Measured with a Visual Analogue Scale (0-10 points). Higher scores mean a worse pain. | At six weeks | 
| Range of movement | Measured with an electrogoniometer | At six weeks | 
| Disability | Measured with the Roland Morris Questionnaire (0-24 points). Higher scores mean a worse disability. | At six weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | 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. | At six weeks | 
| Kinesophobia | Measured with the Fear Avoidance Beliefs Questionnaire | At six weeks | 
| Catastrophizing | Measured with the Pain Catastrophizing Scale (0-52 points). Higher scores indicate higher levels of fear-avoidance beliefs. | 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. | At six weeks |
