Using thermal imaging to measure changes in breast cancer-related lymphoedema during reflexology.

Reflexology lymph drainage (RLD) for breast cancer-related lymphoedema (BCRL) may have a positive impact on arm swelling and pain. Thermal imaging is a means of tracking temperature change by visual images. This study aimed to explore the use of thermal imaging in treatment for BCRL. The swollen arms of two participants with BCRL were photographed using a thermal imaging camera during a single RLD treatment. Limb Volume Circumferential Measurement (LVCM) of both arms was taken before, after and the next day. The images were examined for visual changes, and temperature data were extracted. Images showed differences in temperature within the affected hand and arm over 45 minutes. LVCM data indicated a loss of limb volume in the affected arm in both cases, which continued to decrease over 24 hours. Thus, thermal imaging may be useful in tracking temperature change during treatment for BCRL.
