Biofeedback and Self-Regulation
|December 1, 1982
Summary
Biofeedback training, a self-regulation technique, rarely causes adverse effects. However, one patient experienced acute headaches and nausea after electromyography (EMG) biofeedback sessions.
Area of Science:
- Neuroscience
- Psychophysiology
- Behavioral Medicine
Background:
- Self-regulation strategies, including biofeedback, are generally considered safe.
- Electromyography (EMG) biofeedback is used to train individuals to control physiological responses.
- Adverse events associated with biofeedback are infrequently reported in scientific literature.
Observation:
- A patient, previously without headaches, developed acute headache and nausea episodes.
- These symptoms consistently occurred immediately after early EMG biofeedback training sessions.
- The remission of symptoms was linked to specific conditions, which will be detailed.
Findings:
- This case presents a rare instance of negative side-effects from biofeedback.
- The temporal association suggests a direct link between EMG biofeedback and symptom onset.
- Further investigation into the physiological mechanisms underlying this reaction is warranted.
Implications:
- Clinicians should be aware of potential, albeit rare, adverse reactions to biofeedback.
- Understanding these side-effects may refine biofeedback protocols and patient selection.
- This case highlights the need for continued research into the complex interplay between biofeedback and physiological responses.
