PurposeThe coronavirus 2019 (COVID-19) pandemic led to a compulsory lockdown of 3 months with strict restrictions. The impact of the COVID-19 pandemic has shown broad repercussions on patients with chronic pain; especially for conditions that present a significant emotional participation such as chronic low back pain (cLBP).MethodsWe performed a prospective study on 50 patients. Pre- and 1-month post-lockdown questionnaires such as: the Impact of Event Scale (IES), the Oswestry Disability Index (ODI), the Roland-Morris questionnaire (RMQ) and the visual analogue scale (VAS) for back and leg pain intensity were collected.ResultsThe mean time of the evolution of cLBP was 33.04 months (range 5-120 months). Eighteen (36%) patients improved their cLBP (i-cLBP), whereas for 14 (28%) it was worse (w-cLBP). Cox multivariate proportional hazard model identified that MODIC 1 disc disease [OR 19.93, IC95% (2.81-102.13), p = 0.015] and at-home workouts [OR 18.854, IC95% (1.151-204.9), p = 0.040] were good prognosis factors of the improvement of cLBP while subclinical/mild Covid-19 anxiety (IES score < 26) was a poor prognosis factor in improving cLBP [OR 0.21, IC95% (0.001-0.384), p = 0.009]. Furthermore, pre-lockdown benzodiazepine medication [OR 2.554, IC95% (1.20-9.9), p = 0.002] was a prognosis factor of worse cLBP. In contrast, patients with severe Covid-19 anxiety (IES score > 26) significantly improved their cLBP [OR 0.58, IC95% (0.025-0.834), p = 0.01].ConclusionLockdown affected the somatic component of cLBP by decreasing activities and physical measures, whereas the SARS-CoV-2 pandemic spectrum paradoxically improved the psychic and emotional component of cLBP.© 2021.
