Design and Evaluation of a Controllable Heat Therapy Device with Dynamic Monitoring and Feedback System

Musculoskeletal and neuromuscular disorders comprise diverse conditions affecting bones, joints, muscles, nerves, and connective tissues. These days, muscle strains and spasms are also typical. Heat therapy is used to reduce cellular damage, heal from musculoskeletal injury, and relieve pain from a range of health conditions. The mechanism by which superficial heat therapy improves blood flow and circulation is vasodilation, which causes an area to become warmer. Even a small temperature increase can help to reduce pain and improve muscular elasticity in the affected area. Heat treatment helps repair the damaged tissues as well as relaxation of muscles. Conventional heating pads cannot provide the right temperature required for a particular issue. Additionally, receiving heat therapy from a physiotherapy center is expensive and challenging, particularly for elderly patients. This article provides a design methodology along with an evaluation of the produced controllable heat therapy device, which addresses a critical issue in traditional therapy systems by offering temperature and duration control features crucial for patient safety. Unlike traditional devices, this device includes monitoring mechanisms to prevent burns caused by excessively high temperatures. Users can conveniently adjust settings and monitor the temperature and the timer in real time via a user-friendly mobile app. The device has demonstrated the capacity to enhance the average blood flow rate by an increase of 25-35%. Additionally, it has shown a notable reduction of 2-4 points in the Visual Analog Scale (VAS) pain score. Moreover, the proposed system serves as exceptional telemedicine equipment, offering affordability and usefulness for home settings.
