What is the aim of this medical experiment?

"This 12-month clinical trial will measure the efficacy of a given intervention by assessing changes in pain scores from baseline as measured on the Pain Anxiety Symptoms Scale -- Short Form 20 (PASS SF-20). The quality of life, interference with daily activities and intensity of pain experienced are also to be tracked via responses to questionnaires such as the NIH Toolbox Pain Interference Computer Adaptive Test (CAT) and PROMIS Pain Intensity Scale 3a. A score change of at least 50% is desired when compared against baseline data." - Anonymous Online Contributor
