Implementation of the Specific Treatment Of Problems of the Spine Approach in Bangladesh

Inclusion Criteria: Physiotherapists: Qualified physiotherapists and physiotherapy assistants in Bangladesh who are involved in low back pain management and working in either or both trial settings will provide the treatment in phases 1 and 3. To be eligible, physiotherapists and physiotherapy assistants must be willing to participate in all phases of the trial (Phases I, II, and III). They must have completed the organised STOPS training course led by the original Australian developers (Jon Ford and Andrew Hahne), where the assessment and treatment protocols will be taught in Phase II. Patients: 1. A primary complaint of either: 1. low back pain, defined as pain between the inferior costal margin and the inferior gluteal fold with or without referral into the leg(s) or 2. referred leg pain, defined as predominately unilateral posterior leg pain extending below the knee, or anterior thigh pain, with or without back pain 2. Duration of the current episode of primary complaint lasting for greater than 3 months (chronic stage of the injury) 3. Aged between 18 and 65 (inclusive) 4. Fluency in English or Bengali sufficient to complete questionnaires and to enable understanding of the intervention 5. Agreeing to refrain from other interventions wherever possible for the 10-week treatment period of the trial, aside from consultations with medical practitioners, medication, and any exercises already being undertaken Exclusion Criteria: Physiotherapist: Not willing to participate in the study for all 3 phases. Patient: 1. Red flag pathologies such as active cancer under current treatment, risk of spinal fracture, signs of potential infection, and major systemic inflammatory disease. 2. Signs of cauda equina syndrome based on bladder or bowel disturbance and/or imaging 3. Current pregnancy, or childbirth within the last 6 months, as this could impair the ability to undertake exercises, and could also cause back and leg symptoms that are not related to the subgroups under investigation 4. Spinal injections within the last 6 weeks, as we wish to study treatment effects independent of the effects of injections 5. Any history of lumbar spine surgery, as there is already considerable research evaluating the efficacy of post-surgical rehabilitation programs 6. A pain intensity score of less than 2/10 on the numerical pain rating scale due to low severity. 7. Minimal activity limitation, evidenced by a baseline ability to perform ALL of (walk, sit, and stand for one hour o…
