Key: BMI Body Mass Index (underweight to obese), BBQ Back Beliefs Questionnaire (higher scores = less fear), EQ-5D-5L Euroqol 5 dimension quality of life questionnaire (higher scores = higher perceived quality of life), FABQ Fear Avoidance Beliefs Questionnaire (higher score = more strongly held fear avoidance), FABQ-PA Fear Avoidance Beliefs Questionnaire (Physical Activity), FABQ-W Fear Avoidance Beliefs Questionnaire (Work), IPAQ International Physical Activity Questionnaire (higher score = higher estimated levels of physical activity), ODI Oswestry Disability Index (higher score = higher description of perceived disability), Self-Efficacy Questionnaire (higher scores = stronger self-efficacy beliefs)
