Clinical Trial Summary

The investigators will recruit participants between the age of 18 and 65 with chronic non-specific low back pain and a sedentary lifestyle. The participants will be randomly assigned to one of the three groups. The first group is the control group, the participants will be asked to continue their daily routine. The second group is an intervention group, sedentary behaviour will be reduced. In the third group participants will be asked to increase their physical activity up to 150min/week. The intervention takes place over a period of 6 weeks. After the intervention the pressure pain threshold will be measured, average steps will be measured (accelerometer) and a questionnaire needs to be filled out. These results will be compared to the results before the intervention and to the results of the other groups.

Description:

The investigators will recruit participants between the age of 18 and 65 with chronic non-specific low back pain and a sedentary lifestyle. The partcipants will be randomly assigned to one of the three groups. The first group is the control group, the participants will be asked to not change their daily routine. In the first intervention group sedentary behaviour will be reduced. The participants will be asked to download an app on their smartphone and computer. This app will ask the participants to stand up and walk during 2 minutes to interrupt their sedentary behaviour during working hours. In the second intervention group participants will be asked to increase their physical activity. More specifically the participants will be asked to be active for a period of 150min/week. The intervention takes place over a period of 6 weeks. During these 6 weeks the participants needs to wear an accelerometer the first and the last week of the intervention. The week before the intervention a pre-measurement will take place, this means that the participant needs to wear an accelerometer during a week, fill out a questionnaire (BPI and SF-36) and the pressure pain threshold will be measured. After the intervention (6 weeks) the pressure pain threshold will be measured, average steps will be measured (accelerometer) and a questionnaire needs to be filled out. These results will be compared to the results before the intervention and to the results of the other groups. With this study the investigators will investigate whether less sedentary behavior or more physical activity are beneficial for chronic low-back pain.

Eligibility

Inclusion Criteria:

• Failed back surgery syndrome is allowed (ie, more than 3 years ago, anatomically successful operation without symptom disappearance)

• Desk job, sedentary lifestyle (i.e. sitting for more than 6 hours per day). Given the greater risk of developing serious health problems when sitting for more than six hours a day.

Related Conditions & MeSH terms

• Back Pain
• Chronic Low-back Pain
• Low Back Pain
• Sedentary Behavior

Intervention

Behavioral:
• Reducing sedentary behaviour
This group needs to download an app on their computer and their smartphone. This app will give a notification every 30 minutes to walk during 2 minutes during working hours. The participants will receive a diary to write down whether they stand up.
• Increase physical activity
This group will be asked to be more physically active. They need to be active during 150min/week. It can include walking, to ride a bike, jogging, tennis, football,... Additionnaly they need to be active in periods of at least 10 minutes. The participants will receive a diary to write down which activity they did and also for how long.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Brief Pain Inventory (short form)	Since chronic pain is a rather fluctuating condition, the question "Please rate your pain by circling the one number that best describes your pain on AVERAGE" is used as primary outcome measure to evaluate pain intensity. The answer to this question is formulated on an 11-point (i.e. 0-10) numeric rating scale (NRS), which is recommended as a core outcome measure in clinical trials of chronic pain. 0 indicates no pain, 10 indicates the worst pain imaginable.
