Combining Physiotherapy Group Exercise With Acceptance and Commitment Therapy in Elderly With Chronic Low Back Pain

This two-armed randomized controlled trial (RCT) aims to investigate the effectiveness of Group Exercise with acceptance and commitment therapy led by physiotherapist (GrExPACT) (experimental intervention) as compared to Group Exercise alone (GrEx) (control intervention) for elderly with chronic low back pain (LBP) whom are stratified as medium or high-risk using the STarT Back Screening Tool on functional recovery as measured by Roland Morris Disability Questionnaire as the primary outcome and a list of secondary outcomes which include Committed Action questionnaire, Chronic Pain Acceptance questionnaire, Patient self-efficacy Questionnaire, Brief Pain Inventory, Patient Specific Functional Scale, Short Physical Performance Battery and a patient satisfaction survey, immediately after a 5-week programme as well as at 3-month follow-up. The list of hypotheses to be tested in this RCT include: 1. For main effect: Intervention H0: The outcome means for the intervention of GrExPACT and GrEx are equal H1: The outcome means for the intervention of GrExPACT and GrEx are not equal 2. For main effect: Time H0: The outcome means for the time with measuring point at pre-intervention, immediate after the program and at 3 months are equal H1: The outcome means for the time with measuring point at pre-intervention, immediate after the program and at 3 months are not equal 3. For interaction: Intervention x Time H0: There is no interaction between the intervention and time H1: There is interaction between the intervention and time
