 note = {pdf, The purpose of this study is to examine the effectiveness of the Body Sensory Acoustic System for Groups that was developed on healthy individuals in aiming to harness this for habilitation activities for children or persons with severe motor and intellectual disabilities.
To begin with, 10 non-handicapped persons were given 54-Hz stimulus, which Dr. Olav Skil proposed as a comfortable frequency, for 15 minutes on Body Sensory Acoustic System for Groups. As a result, approximately 60dB was confirmed to be a pleasant stimulus intensity. Based on these results, a total of 60 healthy individuals underwent the stimulus presentation three people at a time via a program of rest – stimulus presentation – rest via three types of conditions: a vibration condition, a music condition, and a music + vibration condition. Psychological evaluations and physiological indicators were used to measure the results. Regarding the psychological evaluations, for each of the programs checks were conducted via a six-part approach that included physical condition, arousal level, and sense of relaxation. Skin temperature, ear temperature (eardrum membrane temperature), salivary amylase values, and heartrate were used for the physiological indicators, with measurements taken for each of these.
From the results it was acknowledged that the music + vibration condition significantly decreased arousal levels and increased positive feelings and a sense of relaxation. In addition, reactions concerning skin temperature, amylase values, and ear temperature from before and after each stimulus presentation were viewed via their incidence rates. Based on this it was acknowledged that skin temperature rose with the vibration condition, amylase values fell with the music + vibration condition, and ear temperature tended to fall with the music and music + vibration conditions. What is more, the deceleration in average pulse rates was significantly greater with the two conditions that involved vibration than with the music condition.
This suggests that presentation of music + vibration at approximately 60dB via the Body Sensory Acoustic System for Groups is received by people as a comfortable stimulus in both a psychological and physiological sense. As such, the thinking is that this can be applied to children or persons with severe motor and intellectual disabilities in the future.},
