Measurement of heat flux density as a new method of diagnosing neurological

Osteochondrosis of the lumbar spine and its neurological manifestations is one of the most common diseases, which leads to impaired working capacity and disability of people mainly at a young age. The issue of tactics for choosing a treatment method (conservative or surgical) remains debatable. The paper presents the results of the development of a thermoelectric device for diagnosing inflammatory processes and pain syndrome in degenerative-dystrophic diseases of the lumbosacral spine. Such a device makes it possible to save, process and visualize measurement results on the display of the device and on a personal computer in real time. It was established that moderate indicators of temperature and heat flux density (HFD) in the paravertebral zone were recorded in the control group. In patients with lumboschialgia without signs of instability, there was a parallel fluctuation of temperature and HFD on the side of pain and low values on the intact side. In the case of lumboischialgia against the background of vertebral instability, the symptom of "scissors" on the side of pain and an increase in both thermal indicators on the intact side were positive. With stenosis of the spinal canal, temperature and HFD decreased on both sides, but more intensively on the side of pain. The results of clinical studies of thermometric indicators in the lumbosacral region of the spine in persons with chronic pain syndrome against the background of degenerative-dystrophic pathology of the spine in the presence of hernias and protrusions of intervertebral discs are also presented. The effectiveness of the proposed thermoelectric device in medical practice has been confirmed.
