- Original description
We will recruit overweight/ obese participants between the age of 18 and 65 with chronic nonspecific low back pain . The participants will be randomly assigned to one of two interventions (each lasting 10 weeks). All interventions will be delivered in a blended format and will be a combination of online education material and face-to-face sessions with a physical therapist. The first group (experimental intervention) will receive a behavioral weight reduction program combined with pain neuroscience education plus cognition-targeted exercise therapy. Participants in the second group (control intervention) will receive pain neuroscience education and cognition-targeted exercise therapy alone. Allocation to the groups will be at random. Participants and assessors will be blinded for group allocation. The primary outcomes is pain intensity. Secondary outcomes include other pain related outcomes, body composition, physical activity, sedentary behavior, dietary intake and function.Read full original descriptionShow less

We will recruit overweight/ obese participants between the age of 18 and 65 with chronic nonspecific low back pain .

All interventions will be delivered in a blended format and will be a combination of online education material and face-to-face sessions with a physical therapist. The first group (experimental intervention) will receive a behavioral weight reduction program combined with pain neuroscience education plus cognition-targeted exercise therapy. Participants in the second group (control intervention) will receive pain neuroscience education and cognition-targeted exercise therapy alone. Allocation to the groups will be at random. Participants and assessors will be blinded for group allocation. The primary outcomes is pain intensity. Secondary outcomes include other pain related outcomes, body composition, physical activity, sedentary behavior, dietary intake and function.
