Background: Peripheral pump dysfunction is important in identifying manifestations of chronic venous insufficiency. The association with disease severity may define better treatment strategies.
Objective: To evaluate the association between peripheral muscular pump performance by heel-rise test, age, physical activity, use of compression stockings, and chronic venous insufficiency clinical severity.
Methods: Subjects with chronic venous insufficiency were enrolled in the study (n = 172) and evaluated by clinical-etiology-anatomy-pathophysiology severity and heel-rise test.
Results: In model 1 of logistic regression, number of heel-rise test repetitions, age, and physical activity explained 47% of clinical-etiology-anatomy-pathophysiology severity (p = 0.0001), physical activity contributed the most. In model 2, heel-rise test repetition rate, age, and physical activity explained 46.4% of clinical-etiology-anatomy-pathophysiology severity (p = 0.0001), repetition rate contributed the most. Conclusion: There was an inverse association between muscular pump performance and physical activity with clinical-etiology-anatomy-pathophysiology severity, muscular pump repetition rate contributed to a less severe outcome.
