Objective To explore the effect of quantitative management of active and passive ankle pump exercise on lower limb venous hemodynamics in elderly patients, and to provide a reference for improving the effectiveness of ankle pump exercise in elderly patients. Methods The self-control study design was used, and 20 elderly patients hospitalized in the geriatric department were selected, then based on relevant literature in domestic and overseas, a quantitative management scheme for ankle pump exercise suitable for elderly patients was developed and command videos were recorded, which were used to guide the patients to perform active and passive ankle pump exercise. Results Two months after the intervention, all the participants didn't suffer from deep vein thrombosis.At 0 and 5 minutes after passive ankle pump exercise, there were statistically significant differences in the maximum blood flow velocity and average blood flow velocity during the popliteal vein contraction period when compared with those after active ankle pump exercise （both P＜0.05）,while there were no statistically significant differences between the two methods 10 minutes and 15 minutes after exercise （both P＞0.05）.Pairwise comparison within the group showed statistically significant differences at different time points and resting time after passive ankle pump exercise （all P＜0.05）, but there was only a statistically significant difference between 0 minutes after exercise and resting time after active ankle pump exercise （P＜0.05）. Conclusion The effect of active ankle pump exercise in elderly patients is not good, while assisting elderly patients to carry out quantitative passive ankle pump exercise can effectively promote their blood circulation of the lower limbs.
