The international Journal of Rehabilitation Medicine has recently published our study titled “Factors associated with pain-related functional interference in people with chronic low back pain enrolled in a physical exercise programme: the role of pain, sleep, and quality of life.” This study is part of the doctoral thesis of our predoctoral researcher Marta Moreno, who is nearing the completion of her thesis by compilation of articles.
This cross-sectional study aimed to analyse the factors associated with functional interference caused by pain in individuals suffering from chronic low back pain (CLBP). The research utilised data from 99 patients included in the PainReApp project, developed by the Pain Observatory in collaboration with the Rehabilitation Unit at Puerta del Mar University Hospital (Cádiz).
The results showed that 37.4%, 27.3%, and 35.4% of our study population with CLBP were classified into low, moderate, and high levels of pain-related functional interference, respectively, as measured by the Pictorial Pain Interference Questionnaire (PPIQ). Additionally, higher PPIQ scores (indicating greater pain-related functional interference) were associated with higher pain intensity, poorer functional mobility, lower sleep quality, the presence of anxiety and depression, reduced muscular strength and endurance, lower physical activity levels, reduced quality of life, and less social support.
Multivariate analysis of the associated factors revealed that higher PPIQ scores were directly linked to pain intensity and poorer sleep quality and indirectly linked to physical and mental components of quality of life, as well as lower consumption of minor opioids.
The study concludes that beyond the presence and intensity of pain in individuals with CLBP, various biopsychosocial factors are associated with this condition. Moreover, higher pain intensity, poorer sleep quality, reduced quality of life, and lower use of minor opioids were linked to greater pain-related functional interference in the studied population.
