The Effect of Reducing Sedentary Behaviour in Comparison to Promoting Physical Activity on Chronic Non-specific Low Back Pain in a Sedentary Population

• Status: Terminated
• Phase: N/A
• Study type: Interventional
• Enrollment: 5 (actual)
• Sponsor: Vrije Universiteit Brussel · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Not accepted

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.

Detailed 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.

Conditions

• Chronic Low-back Pain
• Sedentary Behavior

Interventions

Type	Name	Description
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.
BEHAVIORAL	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.
