Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Perceived disability is measured using the Oswestry disability questionnaire (OSW) at baseline, 4 weeks, 8 weeks and 6 months 2. Pain intensity, measured using an 11-point (0 to 10) numeric pain rating scale (NPRS) to assess the current, best and worst levels of pain intensity during the last week, so as to average the three ratings and obtain a more reliable composite score at baseline, 4 weeks, 8 weeks and 6 months 3. Patient satisfaction is measured using the Physical Therapy Patient Satisfaction (PTPS) questionnaire at 8 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Clinical assessment: Outcomes will be measured at baseline and 8 weeks 1. Posture (pelvic tilt, lordosis, kyphosis) and range of motion is measured using one or two inclinometers 2. Aberrant movements are measured using observations during flexion – extension 3. Lumbar instability is measured using the prone instability test 4. Ligamentous laxity is measured using the Beighton Scale 5. Lumbar instability is measured using painful arc in flexion 6. Lumbar instability is measured using painful arc in return from flexion 7. Posterior chain flexibility is measured using the passive straight leg rising test 8. Load transfer of lumbo-pelvic area is measured using the active straight leg rising test 9. Muscle testing is measured using three brief tests: side support, active set-up, extensor endurance 10. Physical performance is measured using repeated sit-to-stand, repeated trunk flexions, loaded reach and 360 degree rollover Psychological assessment: Outcomes will be measured at at baseline, 4 weeks, 8 weeks and 6 months, unless stated otherwise 1. Fear-avoidance beliefs are measured using the Fear-avoidance beliefs questionnaire (FABQ) 2. Pain catastrophizing is measured using the Pain Catastrophizing Scale (PCS) 3. Psychological distress is measured using the Psychological distress Inventory 4. Activity-related pain is measured by asking participant "Do you experience increased pain during general activity or exercise?" 5. The physical activity level is measured using the Baecke physical activity questionnaire (last month recall) 6. Self-efficacy for exercise is measured using the Self-efficacy for exercise Scale (SEES) 7. Barriers to exercise is measur | — |
