Introduction/Purpose: Foot and ankle (FA) pain can be found in up to 20% of the adult population.1 Etiologies are multifactorial
and include neurologic injury, trauma, deformity, tendinopathies and
psychological factors. The purpose of this investigation is to assess psychological factors contributing to FA pain in surgical and
nonsurgical patients. By identifying how psychological factors influence patient reported pain and disability, clinicians may be able
to develop interventions to decrease catastrophic thinking and improve psychological well-being prior to considering surgical
intervention
Methods: All patients seen in a FA clinic by a single fellowship trained orthopaedic surgeon from August 2016 to October 2016
were included. All patients completed 5 functional assessments prior to their visit (PHQ-2, VAS Pain Scale, FAAM, PSEQ, PCS).
We divided the patients into two groups based on their performance on the PHQ (PHQ < 3, or PHQ = 3), which measures
depression. Scores = 3 are indicative of clinical depression. Nonparametric Wilcoxon testing was used to determine whether
the distributions of the other scores (VAS Pain Scale, FAAM, PSEQ and PCS) were significantly different between these two
groups.
Results: Of the 225 patients included in our analysis, there were 175 (88%) had PHQ-2 depression scores of < 3 (Group 1) and
50 (22%) had scores = 3 (Group 2). Group 2 demonstrated a statistically significant increase in VAS Pain Scale and PCS. In
addition, patients in Group 2 showed statistically significant decreases in FAAM and PSEQ. Patients in Group 2 were statistically
more likely to be obese, use tobacco, and be unemployed.
Conclusion: In patients with common FA complaints, those with clinical depression, as assessed by the PHQ-2, demonstrated
increased pain scores, decreased ability to cope with pain, and lower functional outcome scores compared to patients without
depression. Tobacco use, obesity and employment status were found to independently affect pain, coping, and function of
patients. These data suggest that depression can significantly affect a patient’s ability to cope with pain and to achieve a higher
functional outcome. This data suggests patients with depression may have increased difficulty coping with their FA ailment leading
to the need for increased counseling regarding expected outcomes.
