Abstract:
The therapeutic effect of applying photic stimulation was evaluated in a sample of 17 patients with chronic tinnitus. The employed optical stimulation technique triggers the activity of brain waves and induces deep relaxation characterized by increased EEG activity in the theta and delta spectrum. The expected therapeutic effect beyond relaxation was a decrease in subjective tinnitus distress and further improvements in well-being. All patients received ten applications of photic stimulation, each lasting 30 min. Every application markedly increased the peripheral blood circulation, thus indicating a relaxation effect. The emotional and cognitive impairments as well as the subjective tinnitus distress significantly decreased during treatment while sleep disturbances showed a tendency towards improvement. Overall, tinnitus distress markedly decreased and general well-being improved. The photic stimulation technique is proposed as a relief for tinnitus patients who do not respond to conventional relaxation techniques.
