Assessing the Influence of Unstable Footwear on Lower Limb Lymphedema

Introduction: Unstable shoes may benefit lower limb lymphedema patients by reducing foot volume and relieving symptoms. Objective: The objective of this study was to evaluate and compare the effectiveness of unstable shoes versus conventional sports shoes in managing lower limb lymphedema, focusing on changes in foot volume, circumference, and symptom relief. Methods: We conducted an 8-week clinical trial, recruiting patients with lower limb lymphedema. Participants were divided into 2 groups: one using unstable shoes and the other using conventional sports shoes. Measurements of foot volume and circumference were taken at the beginning and end of the trial. Additionally, participants were asked to report any changes in leg cramps and paraesthesia during the study period. Results: The results indicated a nonstatistically significant tendency toward a decrease in foot volume and circumference in the intervention group using unstable shoes. In contrast, the control group using conventional sports shoes showed a tendency toward an increase in foot volume and a statistically significant increase in foot circumference. Moreover, participants in the unstable shoes group reported a decrease in leg cramps and paraesthesia, indicating potential symptom relief. Conclusions: This study suggests that unstable shoes have the potential to offer benefits to individuals with lower limb lymphedema, particularly in terms of foot volume reduction and symptom relief. The use of unstable shoes may be suitable for activities such as walking and extended periods of standing. However, further research is necessary to explore their full potential and effectiveness in managing lymphedema symptoms comprehensively.
