Difficult life events affect lower extremity illness.

BACKGROUND

Given the relationship between psychological distress and activity tolerance (capability), a stressful life event might diminish accommodation, increase symptoms, and induce a person to seek specialty care. As a first step to investigate this possibility, this study addressed whether difficult life events are associated with greater activity intolerance and pain intensity.

METHODS

A cohort of 127 patients seeking specialty care for lower extremity symptoms completed questionnaires that inquired about difficult life events within the last 12 months as derived from the Holmes Rahe Life Stress Inventory, and recorded pain intensity on an 11-point ordinal scale, activity tolerance [Patient Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (CAT)], symptoms of anxiety (GAD-2; 2 item version of the Generalized Anxiety Disorder questionnaire), symptoms of depression (PROMIS Depression CAT), self-efficacy when in pain (Pain Self-Efficacy Questionnaire, 2 question version), and demographics. The treating clinician indicated if the disease was established (e.g. arthritis) or relatively new (e.g. sprain/strain). Bivariate and multivariable analyses sought factors associated with activity intolerance and pain intensity.

RESULTS

Greater activity intolerance was associated with difficult life events in bivariate analyses (t = 2.13, MD = 3.18, 95% C.I. = 0.22-6.13, p = 0.04) and in multivariable analyses that excluded symptoms of depression. Greater pain intensity was not associated with difficult life events, but was associated with surgeon rating of established disease (β = 1.20, 95% C.I. = 0.33-2.08, p < 0.01), greater symptoms of anxiety (MD = 3.35, s = 1.72; ρ = 0.30, p < 0.01), and less education (β =  - 1.06, 95% C.I. =  - 1.94- - 0.18, p = 0.02) (no college degree).

CONCLUSION

When a musculoskeletal specialist identifies less activity tolerance (less capability) than anticipated for a given injury or pathology, they can anticipate a potential difficult life event, and expect alleviation of symptoms and improved capability as the stress is ameliorated with time and support. Specialists can be prepared to direct people to community or professional support if requested.
