Overview
Brief Summary
Chronic shoulder pain is a common, costly, and disabling problem for society. The identification of factors predictive of the development of chronic shoulder pain is necessary to develop innovative and effective treatments to reduce the societal impact of shoulder disorders. In previous work the investigators identified a genetic and psychological subgroup that robustly predicted heightened shoulder pain responses in a pre-clinical cohort and poor 12 month shoulder pain recovery rates in a clinical surgical cohort. In this follow-up study the investigator proposes to test how interventions tailored to the high risk subgroup affect pain responses in a pre-clinical cohort.
The optimal theorized match for the identified high-risk subgroup is a combination of personalized pharmaceutical and education interventions. This combined personalized intervention versus a placebo pharmaceutical and general education intervention group is the primary comparison of interest. Also, an evaluation of the individual effect of personalized pharmaceutical and educational interventions will be part of the study. Such comparisons will provide important information on what the active portion of the combined personalized intervention may be.
Detailed Description
Potential subjects will be screened and those meeting the high-risk criteria based on COMT genotype for high pain sensitivity and pain catastrophizing questionnaire score will be eligible for randomization into intervention groups (stratified by sex). Exercise induced shoulder injury will serve as the pain generating mechanism on Day 1 and participants will receive pharmaceutical and education interventions over Days 1-4, and Days 2-4 respectively. Statistical analysis will determine whether the combined personalized intervention group experienced shorter shoulder pain duration, lower peak pain intensity, or decreased upper-extremity disability and determine which molecular, psychological, and pain sensitivity regulation mechanisms are associated with pain relief. A preliminary analysis is planned after the first 300 subjects are equally randomized to the 4 intervention groups. The comparison of interest for the preliminary analysis is the combined personalized intervention group with the placebo and general education group for the primary outcome. Depending on the results of this preliminary analysis the randomization pattern may change, with details of these changes available in the protocol paper.

Outcomes
Primary Outcomes
Number of Participants Who Met the Recovery Criterion for Shoulder Pain Intensity
Time Frame: Approximately 6 days
The outcome has a range between 0 and 1, the higher scores mean a better outcome. Successful recovery was determined based on meeting the recovery criterion for shoulder pain intensity by at least 6 days. Specifically, recovery (Yes or No) was defined using Brief Pain Inventory (BPI) ratings as a current pain intensity rating of 0/10 and a worst pain intensity rating of less than 2/10.
Secondary Outcomes
- Brief Pain Inventory (BPI) for Pain Duration(Daily until recovery criterion met, approximately 5-15 days)
- Disabilities of the Arm, Shoulder, and Hand Questionnaire (DASH)(Daily until recovery criterion met, approximately 5-15 days)
- Brief Pain Inventory (BPI) for Worst Shoulder Pain Intensity (Highest Daily Pain Intensity Rating) Recorded During Recovery.(Day 2 value of the worst pain intensity is reported)
