Developing short screening tools might reduce the data collection burden and facilitate screening, which could prompt further testing or management strategy modifications to improve outcomes. OBJECTIVE The purpose of(More)
OBJECTIVES To (1) determine the prevalence of pain pattern classification subgroups (centralization, noncentralization, and not classified) observed during the initial evaluation of patients experiencing high versus low Fear-Avoidance Beliefs Questionnaire for physical activity (FABQ-PA) scores, (2) examine the association between discharge pain intensity(More)
