Interventions: Group 1- Control group: Outcome assessments will be conducted on patients on the wait list for physiatry consultation at baseline, 6 weeks, and 3 months. Group 2 - Intervention group (MDT group): Consistent with the MDT approach, patients will be initially assessed for centralisation over 2 visits by a Credentialed MDT therapist and further classified into centraliser (group 2a) and non-centralising pain responses (group 2b). A centralising pain response is defined as those whose most distal pain is reduced and retreats toward mid-line (e.g., pain now above knee) in response to certain postures and repeated end-range movement testing. Group 2a, Centralisers: Patients with a centralising pain response will continue with treatment based on MDT principles and will complete an exercise diary to indicate the frequency in which the exercises were performed daily. Group 2b, Non-centralisers: Patients with a non-centralising pain response will be offered TESIs followed by MDT. TESIs of 20mg dexamethasone and 0.5cc lidocaine 2%, under fluoroscopic guidance with contrast medium (Omni Pac 240) as described by the Spine Intervention Society (SIS) guidelines will be provided. Segment level will be determined based on MRI findings in combination with the clinical examination findings.
