Does Fear of Movement Affect Fatigue and Quality of Life in Lower Extremity Lymphedema?

Background: The aim of our study was to determine the causes of lower extremity kinesiophobia (whether it is biological or psychological) in individuals with lower limb lymphedema (LLL), and to compare the changes in fatigue and activities of daily living with healthy individuals. Methods: The study included 74 unilateral LLL patients (study group) and 74 individuals (control subjects). Causes of fear of movement were assessed with the Causes of Fear of Movement questionnaire; fatigue, with the Functional Assessment of Chronic Disease Treatment-Fatigue Questionnaire; and quality of life (QoL) with the Lymphedema Quality of Life Questionnaire-Leg. Results: One hundred forty-eight participants were included in the study, 74 of whom were in the study group and 74 in the control group. 63.5% of the lymphedema patients had primary lymphedema and 36.5% had secondary lymphedema. Fear of movement total score and QoL scores was higher in LLL group than control group. Total fear of movement score and biological subparameter score of fear of movement, fatigue, and some subparameters of QoL scores were found to be higher in primary LLL patients compared with secondary LLL. Conclusion: Fear of movement is common and QoL is impaired in patients with secondary LLL, more significant in primary LLL.
