Introduction. The cranial rhythm is represented by the rhythmic movement of the skull bones associated with the cyclic changes in production and pressure of the cerebrospinal fluid. The existing methods of instrumental recording of the quantitative characteristics of the cranial rhythm are either invasive, either contact, or very complex. Objective. To evaluate the EHF-bioradiolocation method as a method of recording of the quantitative characte-ristics of the cranial rhythm. Methods. Twenty

... unteers were examined. At the first stage of the study, we determined the optimal conditions for registering the cranial rhythm with the help of the EHF bioradiolocator. At the second stage, the volonteers' cranial rhythm was registered with the use of an EHF-bioradiolator. Then the volonteers were subjected to osteopathic diagnostics and correction. After that the cranial rhythm was recorded again. Results. For the first time we registered the cranial rhythm with the help of the EHF-bioradiolocator. In most cases, the frequency of the cranial rhythm recorded by the device coincided with the frequency determined by an osteopath. After the osteopathic treatment, the total amplitude of the oscillations increased in all the patients. Assessment of changes in the frequency of the cranial rhythm was difficult due to the presence of several harmonics. Conclusion. With the help of the EHF-bioradiolocator, it is possible to register the quantitative characteristics of the cranial rhythm - frequency and amplitude. The methodology we developed is safe and relatively simple. It is non-contact, and can be used both for diagnostic purposes, and for monitoring and evaluation of the treatment results.
