Development of Pressure Sensors to Help Support Community Lymphedema Monitoring: A Scoping Review

Breast cancer-related lymphedema is a condition occurring after a partial or full mastectomy, where there is a buildup of interstitial fluid in the body, particularly in the upper limb. There is a lack of at-home sensors that can help monitor the progression of lymphedema. The purpose of this scoping review is to gather relevant information on sensors for remote lymphedema monitoring. A literature search of Medline, PubMed, Scopus, Web of Science, and BMC databases yielded 96 studies. A total of six studies were selected for data extraction. Data were extracted from each study and organized into tables for analysis. A total of six different devices were mentioned in the six studies included in the scoping review, divided into wearable and nonwearable sensors. Nonwearable sensors were more likely to be adaptable for remote sensing as they were further along in development and commercially available on the market. Nonwearable sensors are more developed than wearable sensors for the purpose of remote lymphedema monitoring. This review advocates further development and validation of sensors for lymphedema management, particularly for remote monitoring and health assessments.
