Two weeks after completion of the MDT or TESI intervention, patients will be reassessed and treated in a manner consistent with their presenting pain response classification: 1) resolved: advice on remaining active; 2) centralising: treated according to MDT principles with direction specific exercises and postural advise; 3) non-centralising but significant less pain: advice to remain active, with respect for worsening leg pain; and 4) persisting high levels of pain and/or disability: advise to remain active as tolerated and consult family physicians. Those who continue to perform MDT exercises will complete an exercise diary to indicate the frequency in which the exercises were performed daily
