OBJECTIVE: To reach consensus on the most important biopsychosocial factors that
influence functional capacity results in patients with chronic nonspecific
musculoskeletal pain, arranged in the framework of the International
Classification of Functioning, Disability and Health.
DESIGN: Three-round,
internet-based Delphi survey. SETTING: Not applicable. PARTICIPANTS: Participants
were scientists, clinicians, and patients familiar with functional capacity
testing. Scientists were invited through purposive sampling based on the number
of relevant publications in peer-reviewed journals. The scientists recruited
clinicians and patients through snowball sampling. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Consensus was reached if at least moderate influence (25%)
was achieved and an interquartile range of no more than 1 point was reached.
RESULTS: Thirty-three scientists, 21 clinicians, and 21 patients from 9 countries
participated. Participants reached consensus on 6 factors that can influence the
outcome of the lifting test, having a median of severe influence (50%-95%):
catastrophic thoughts and fear, patient adherence to "doctor's orders," internal
and external motivation, muscle power, chronic pain behavior, and avoidance
behavior. Motivation, chronic pain behavior, and sensation of pain were the top 3
factors affecting postural tolerance and repetitive movement functional capacity
tests. Furthermore, participants reported 28 factors having a median of moderate
influence (25%-49%) that could influence the outcome of lifting, postural
tolerance, and repetitive movement tests. CONCLUSIONS: Overall, chronic pain
behavior, motivation, and sensation of pain are the main factors that can
influence functional capacity results. We recommend that scientists and
clinicians, respectively, consider the most important factors when planning
future studies and when interpreting functional capacity test results.
