Sahid Method for Secondary Unilateral Lower Limb Lymphedema

Manual lymphatic drainage (MLD) is a non-invasive technique frequently used in the management of lymphedema. The Paloma Sahid Method is a patented approach to lymphatic drainage that combines specific manual and mechanical maneuvers and compression. This single-arm clinical trial will evaluate its effects on lower-limb circumference, functional capacity, and quality of life in adult women with secondary unilateral lymphedema. Thirty-two women aged 30-65 years with stage I-II secondary lymphedema affecting one lower limb will be enrolled through referrals from vascular physicians in public and private centers in the Metropolitan Region of Santiago, Chile. Participants will attend two pre-intervention visits: (1) study information and informed consent; (2) baseline assessments including thermography, body composition and BMI (bioimpedance), blood pressure and heart rate, limb volume by circumferential tape measurements, muscle strength by handheld dynamometry, quality of life (LYMQOL), and function (Lower Extremity Functional Scale, LEFS). A randomized subsample of 10 participants will undergo lymphoscintigraphy before and after treatment to characterize lymphatic circulation. The intervention consists of 12 sessions of lymphatic drainage using the Paloma Sahid Method, delivered three times per week over one month (about 80 minutes per session). Maneuvers follow linear sliding patterns directed toward regional lymph nodes and are complemented by compression therapy. After completing the 12 sessions, all baseline assessments are repeated. The primary objective is to determine change in lower-limb circumference from pre- to post-intervention. Secondary objectives include changes in functional capacity, quality of life, thermographic patterns, body composition, muscle strength, hemodynamic measures, and, in the subsample, lymphoscintigraphy findings. The study aims to provide rigorous clinical evidence on a promising, non-surgical option for individuals living with lymphedema.

Lymphedema Surveillance Study

This study is being done to find out how many women develop lymphedema after an axillary lymph node dissection. The investigators also want to look for reasons why some women get lymphedema and others don't. Specifically, the investigators want to do tests on the breast tissue that is removed at the time of surgery to see if they can identify inflammation in the breast tissue, which may increase a woman's risk for lymphedema. The investigators will also ask the patient to answer questions to see how much their quality of life is affected by lymphedema, and whether this study can help women by detecting lymphedema earlier.

If participants are undergoing a therapeutic lymphatic procedure, they will be asked to complete a questionnaire and undergo lymphedema volume assessments as part of the study. If participants are undergoing a prophylactic lymphatic procedure, they will only be asked to undergo limb volume assessments. Participants will be asked to comply with the follow-up visits as outlined in the protocol.

Effects of Extracorporeal Shock Wave Therapy and Pulse Electromagnetic Field Therapy on Lymphoedema

Lymphedema occurs not only in patients with breast cancer and gynecological cancers but also in those where lymphatic drainage is obstructed. Accumulation of lymphatic fluid within tissues results in limb swelling. Additionally, proteins present in lymphatic fluid might lead to fibrosis within tissues, causing various challenges for patients. The changes in volume and weight can significantly impact daily life activities such as eating, brushing teeth, and other routine tasks. Furthermore, it can lead to clothing difficulties and provoke unwanted attention due to aesthetic concerns. Currently, there is no definitive treatment for lymphedema. However, prospective research has shown promising results in applying extracorporeal shock wave therapy (ESWT), originally used for musculoskeletal disorders like plantar fasciitis, tennis elbow, frozen shoulder, and non-union fractures, to lymphedema patients. Similarly, Pulse Electromagnetic Field Therapy (PEMFT), widely used for pain management and muscle strengthening, has the potential for treating lymphedema as it can enhance blood circulation and stimulate muscle contractions. This research project aims to explore the effectiveness and sustainability of using ESWT and PEMFT for lymphedema patients. By applying these therapies to lymphedema patients, this study aims to evaluate their treatment outcomes and long-term effects.

Detecting the Undetected: Heart Failure Screening at the Lymphoedema Point of Care

Heart failure affects more people than the four most common cancers combined. When identified early, management is more straightforward, preventing complications, hospitalisations, and fatalities. Breathlessness and fatigue are cardinal symptoms of heart failure that can present in a number of conditions. As a result, leg swelling, the third cardinal symptom, is the first noted in many people. The presence of leg swelling leads to patients being seen in lymphoedema clinics before the need for cardiology investigation has been identified. Lymphoedema is the presence of chronic oedema as a result of congenital abnormalities, inflammation, infection, trauma, or cancer and its treatments. The vast majority of lymphoedema patients have swelling in their legs. A recent study has shown that 9.4% lymphoedema patients need to be investigated for heart failure. At present, the need for investigation is identified by performing a laboratory blood test, which takes time to arrange and complete. An alternate point of care test can provide a result in 12-minutes at the lymphoedema appointment, and enable appropriate action to be taken. This can reduce the demands on primary care and shorten the chain of events to a specialist assessment, as well as reducing inappropriate referrals. This research, funded by NHS Wales Performance and Improvement, will perform a point of care test to screen for possible heart failure in lymphoedema clinics and establish the clinical utility by exploring the experiences of patients and staff involved and determining the health economic benefits. A supplementary aim is to compare the point of care test to the currently used laboratory test in a subsample to promote confidence in the test and support efforts to spread and scale across all health boards in Wales on completion.

Multimodal Ultrasound for Differentiating Lymphedema and Lipedema

The aim of this observational study is to evaluate the diagnostic value of multimodal ultrasonography in differentiating between lymphedema and lipedema. Differentiating these two chronic conditions based solely on clinical examination can be challenging due to overlapping symptoms. This study will utilize various non-invasive ultrasound techniques-including B-mode ultrasound, strain elastography, power Doppler, and quantitative ImageJ analysis-to compare tissue characteristics among patients with lymphedema, patients with lipedema, and healthy controls. The goal is to identify reliable, non-invasive imaging biomarkers that can facilitate early and accurate diagnosis, thereby optimizing patient management.

Longitudinal Body Composition Assessment in Breast Cancer Patients

This observational cohort study aims to track longitudinal changes in body composition, including skeletal muscle mass and fat distribution, in patients diagnosed with breast cancer. Following primary surgery and adjuvant therapy, participants will be monitored over a 2-year period. The primary objective is to evaluate the natural progression of skeletal muscle mass index (SMI) and metabolic changes in this population. By conducting serial measurements, this study seeks to characterize the longitudinal trends in muscle loss and body composition shifts post-treatment, providing data to better understand the physiological impact of the cancer recovery process.

Impact of Virtual Reality (VR) Based Exercises on Lower Limb Lymphedema Outcomes (LELO)

This randomized controlled study aims to investigate the effects of virtual reality (VR)-assisted gait training, in addition to Complex Decongestive Therapy (CDT), on gait parameters, physical function, quality of life, and edema levels in patients with lower extremity lymphedema. Lymphedema is a progressive condition characterized by the accumulation of protein-rich fluid due to lymphatic drainage insufficiency, leading to chronic inflammation and fibrosis. It impairs gait patterns and reduces functional mobility. VR technologies, such as the RehaWalk system, provide interactive, personalized rehabilitation environments that enhance motor learning, motivation, and adherence to treatment. The study evaluates spatiotemporal gait parameters, three-zone foot analysis (heel, midfoot, forefoot), limb circumferences, ultrasound measurements (dermis, epidermis, subcutaneous fat thickness), and patient-reported outcomes. VR-based training offers a novel, engaging approach to improve physical rehabilitation outcomes in patients with lower limb lymphedema. No significant risks are expected in this study.

Investigation of the Effectiveness of Progressive Resistance Exercise Training in the Management of Lymphedema.
