Snoezelen elicits changes in brain-injured subjects and controls' EEG activity.Our results support the notion that Snoezelen affects the central nervous system.Snoezelen participants are more relaxed after the stimulation.Cognitive deficits of brain-injured subjects may diminish the benefits of Snoezelen.Our study could contribute to design personalized non-pharmacological interventions. Background and objectiveThe aim of this study was to assess the changes induced in electroencephalographic (EEG) activity by a Snoezelenź intervention on individuals with brain-injury and control subjects. MethodsEEG activity was recorded preceding and following a Snoezelenź session in 18 people with cerebral palsy (CP), 18 subjects who have sustained traumatic brain-injury (TBI) and 18 controls. EEG data were analyzed by means of spectral and nonlinear measures: median frequency (MF), individual alpha frequency (IAF), sample entropy (SampEn) and Lempel-Ziv complexity (LZC). ResultsOur results showed decreased values for MF, IAF, SampEn and LZC as a consequence of the therapy. The main changes between pre-stimulation and post-stimulation conditions were found in occipital and parietal brain areas. Additionally, these changes are more widespread in controls than in brain-injured subjects, which can be due to cognitive deficits in TBI and CP groups. ConclusionsOur findings support the notion that Snoezelenź therapy affects central nervous system, inducing a slowing of oscillatory activity, as well as a decrease of EEG complexity and irregularity. These alterations seem to be related with higher levels of relaxation of the participants. |
