Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Objectives: To determine the association between priming and measurements of hand function such as grip strength Primary null hypothesis: There is no difference in grip strength (best of three attempts) as a percent of the opposite hand between patients that complete the standard Pain Catastrophizing Scale (PCS) compared to patients that complete the positively adjusted PCS. Secondary null hypotheses: There is no difference in grip strength (last of three attempts) as a percent of the opposite hand between patients that complete the standard PCS compared to patients that complete the positively adjusted PCS. There is no difference in grip strength (best of three attempts) before and after completing the questionnaires between patients that complete the standard PCS compared to patients that complete the positively adjusted PCS.
