Biofeedback in psychomotor training. Electrophysiological basis

Area of Science:

• Neuroscience
• Music Performance
• Biofeedback

Background:

• Musicians utilize technical practice for optimal performance.
• Electrophysiological markers can indicate optimal performance states.
• Biofeedback may enhance traditional practice methods.

Purpose of the Study:

• To investigate the effects of traditional musical practice versus practice supplemented with alpha-EEG/EMG biofeedback.
• To analyze electrophysiological changes associated with each practice method.
• To determine the influence of initial EEG characteristics on biofeedback efficacy.

Main Methods:

• Thirty-nine music students participated in the study.
• One group engaged in traditional technical practice.
• The other group combined practice with alpha-EEG/EMG biofeedback sessions.

Main Results:

• Traditional practice led to increased integrated electromyography (EMG) power and decreased alpha activity in some students.
• Alpha-EEG/EMG biofeedback resulted in enhanced EEG alpha rhythm frequency, bandwidth, and activation in all subjects.
• Biofeedback also decreased overall EEG integral power.

Conclusions:

• Alpha-EEG/EMG biofeedback significantly modulated electrophysiological markers related to music performance.
• The effectiveness of biofeedback and psychomotor learning is contingent upon individual baseline EEG alpha activity.
• Biofeedback presents a promising adjunct to traditional practice for musicians.
