Conclusion. According to the results of local infrared thermometry in the area of regional biomechanical disturbance at the neck level, patients with dorsopathy have a decrease in local temperature, as well as the presence of functionally significant (>0,4 °С) thermoasymmetry in comparison with patients in whom at this level either local level SDs were diagnosed or no dysfunction was detected at all. The obtained data allow us to speak about the validity of differentiation of dysfunctions of different levels, as well as objectify the hydrodynamic component of SD.
