Abstract:

Objective To explore the application effect of ALACT Reflection Model combined with segmented video in self-care education for patients with secondary lower extremity lymphedema. Methods A randomized controlled trial was conducted. A total of 62 outpatients with secondary lower limb lymphedema were recruited from the Department of Lymphatic Surgery of a tertiary Grade A hospital in Zhejiang Province from November 2025 to February 2026. The patients were divided into a control group and an experimental group using a random number table，with 31 patients in each group. The control group received routine health education，while the experimental group received health education guided by the ALACT Reflection Model and segmented videos. Before intervention and after 12 weeks of intervention，indicators including bilateral lower limb bioimpedance and tissue water content，patient activation and self-management efficacy were compared between the two groups. Results After 12 weeks of intervention，the bioelectrical impedance values and water content of both lower limbs，as well as the scores of patient activation and self-management efficacy in the experimental group were superior to those in the control group（P<0.05）. Conclusion Self-care education based on the ALACT Reflection Model and segmented videos for patients with secondary lower limb lymphedema can effectively relieve limb edema，and improve their self-care enthusiasm and self-management efficacy.
