Can the Medical Resonance Therapy Music affect autonomous innervation of cerebral arteries?

UNLABELLED: The purpose of this investigation was to study the effects of Medical Resonance Therapy Music (MRT-Music) upon autonomous innervation of cerebral arteries by examining slow spontaneous oscillations of cerebral blood flow (SSO) using transcranial Doppler ultrasound (TCD). TCD detects SSO with 3-9 cycles per minute (M-waves) and 0.5-2 cycles per minute (B-waves). The SSO are caused by rhythmic diameter changes of the medium and small cerebral arteries. Six patients aged 24-65 years suffering from tension headache were treated with MRT-Music. Twelve additional patients were examined with TCD only to register SSO for further spectral analysis. After fast Fourier transformation four groups of peaks were registered on the SSO spectra, divided into four rhythms: A. 0.0-0.02 Hz, B. 0.02-0.033 Hz, C. 0.06-0.09 Hz, D. 0.09-0.15 Hz and an intermediate diapason of 0.034-0.059 Hz. Spectral analysis of the SSO showed changes between initial and final amplitude peaks in all patients. In contrast to A-, B-and D-rhythms, the reduction of peaks in the C-diapason was statistically significant (31-60%, P 3D0.04, CI 3D95%) for patients treated with MRT-Music. All patients treated with the MRT-Music reported a relief of headache while and after treatment.

CONCLUSION: SSO may represent an equilibrium in autonomous innervation of the cerebral arteries. The MRT-Music affects the functioning of the brain structures concerning autonomous nervous system and works as a non-chemical sympatholythic. Registration of the SSO is a useful tool to prove an influence of the MRT-Music upon the autonomous regulation of cerebral vessels.
