Investigation of the Effects of High-Intensity Interval Exercise and Moderate-Intensity Continuous Exercise on Limb Volume, Functional Capacity, and Quality of Life in Patients With Lipedema

This randomized controlled clinical study aims to investigate and compare the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), when combined with intermittent pneumatic compression (IPC) therapy, on limb volume, functional capacity, pain, fatigue, anxiety, depression, sleep quality, and quality of life in women with lipedema. Lipedema is a chronic, progressive adipose tissue disorder primarily affecting women, characterized by abnormal and symmetrical fat accumulation in the lower extremities that does not improve with weight loss or limb elevation. It is often misdiagnosed as obesity or lymphedema, leading to delayed treatment. Lipedema causes pain, swelling, bruising, mobility limitation, and reduced quality of life. Conservative treatment options include compression therapy, manual lymphatic drainage, and exercise. IPC is a non-invasive treatment used to reduce limb volume and pain while improving function and quality of life. Exercise is also a cornerstone of conservative management, but the optimal exercise intensity for lipedema remains unclear. In this study, 69 female patients aged 18-65 years diagnosed with lipedema according to Halk and Damstra criteria will be randomly assigned into three groups: IPC + Home-based walking program IPC + High-Intensity Interval Training (HIIT) IPC + Moderate-Intensity Continuous Training (MICT) All participants will receive 15 IPC sessions (3 times per week for 5 weeks). The exercise programs (HIIT or MICT) will continue for 10 weeks, supervised by a physiotherapist. The home-based group will be encouraged to walk ≥10,000 steps daily using a pedometer application. Primary outcome: Change in limb volume measured by circumferential measurements and the truncated cone formula. Secondary outcomes: Pain (VAS), functional capacity (6-Minute Walk Test), muscle strength (dynamometry), pressure pain threshold (algometry), physical activity (IPAQ-SF), lower extremity functi
