Efficacy of a Brief Biofeedback Intervention on Mood, Arousal, Mental Workload, Movement Time, and Biofeedback Device Preference.

Biofeedback (BF) training has been utilized with performers for years. Previous literature highlights the effectiveness of multi-week intervention protocols, but there is a lack of evidence for abbreviated interventions using portable devices and the performer's preference of these devices. Therefore, we investigated the effects of a brief BF intervention on mental workload, mood, arousal, and movement time and BF device preference.
