GSR2
From Wikipedia, the free encyclopedia
The GSR2 is one of the first consumer biofeedback devices designed for the general public in 1976 to teach stress control. Its unique feature is that unlike other devices at the time, it was designed to be held in the hand in an ergonomic manner — without the need for external electrodes. Changes in sympathetic nervous system activity are translated into a rising and falling tone — the higher the pitch of the tone, the greater the SNS activity. In the early 80's the GSR2 was combined with 10 behavioral management programs including a workbook and tapes to aid in the treatment of a wide variety of disorders, including weight control and smoking. It has been purchased by over 500,000 individuals and therapists. It has also been used by thousands of professional and olympic athletes to enhance peak performance. A Windows program called Calmlink was developed for use with GSR2. The program collects data from the device and displays data on the computer screen.
