Pain neuroscience education and therapeutic exercise for the treatment of sequelae in breast cancer survivors living with chronic pain: A pilot study

Abstract

BackgroundBreast cancer represents the most common type of malignant neoplasm worldwide. Advances in diagnosis and treatment have increased the life expectancy of patients. However, the sequelae associated with the treatment of the disease such as chronic pain, kinesiophobia and loss of physical function in breast cancer survivors (BCS) are a long-term health problem. Therapeutic strategies are required for the treatment of chronic sequelae in this population. ObjectivesTo evaluate the effectiveness of a pain neuroscience education (PNE) and therapeutic exercise (TE) for the treatment of chronic sequelae in BCS. MethodsQuasi-experimental repeated measures study. The intervention lasted 9 weeks, with 3 educational and 24 exercise sessions. Pain frequency and intensity (VAS scale), neuropathic pain (DN4), kinesiophobia level (TSK-11V), central sensitization (CSI-Sp), functionality of the affected arm (ULFI-Sp) and active joint range (ROM) with goniometry were measured at baseline, 3rd, 6th and 9th week. Statistical analysis included Friedman's test and ANOVA according to normality criteria. ResultsA total sample of 26 BCS participate in the study. Significant statistical changes were found from the 3rd week of treatment in the frequency and intensity of pain, kinesiophobia and neuropathic pain (p < 0.05). All variables had significant changes at the 9th week (p = 0.001). ConclusionThe results of the present investigation suggest that the combination of PNE and TE are effective in treating sequelae at short term in BCS with chronic pain.
