Key result
Peripheral biofeedback training significantly increased electrodermal resistance across multiple pediatric patient groups, indicating a successful reduction in sympathetic arousal and stress.
Why the study?
There was an interest in medicine to measure stress in an appropriate, fast way with minimal cost, leading to this evaluation of electrodermal activity and biofeedback in paediatric practice.
Does electrodermal response (EDR) biofeedback training improve stress control (measured by skin resistance) in pediatric patients with various chronic and stress-related conditions?

GSR may enable low-cost stress monitoring; leaves open routine clinical use pending validation.
Stress, as a kind of emotion, is inevitable in everyday life. In psychosomatic medicine stress represents a powerful link in the pathophysiological chain of disorder. Having evidence about the power of stress on the body, the interest in medicine was how to measure it in appropriate, fast way and with minimal cost. Electrodermal activity seems to be available for this purpose. The galvanic skin response (GSR) is an objective, transient indication of autonomic nervous system arousal in response to a stimulus. It refers to changes in sweat gland activity that are reflective of the intensity of our emotional arousal. In this article we discuss physiological specifics of skin conductance/resistance and how it is measured in practice. The most used application of GSR is in biofeedback methodology. Biofeedback assessment and training exactly uses skin reaction to different stimuli and aims to gain voluntary control over this autonomic response. The aim of this article is to show effectiveness of this method in paediatric practice.

Pop‐Jordanova et al. (2020) studied Pediatric chronic and stress-related disorders. Peripheral biofeedback (electrodermal response) vs. Baseline (pre-training) was evaluated on Change in electrodermal resistance (EDR) from the first to the last biofeedback session (p=<0.01). Peripheral biofeedback training significantly increased electrodermal resistance across multiple pediatric patient groups, indicating a successful reduction in sympathetic arousal and stress.
