Nociceptive blink reflex habituation biofeedback in migraine

Area of Science:

• Neuroscience
• Clinical Neurology
• Pain Management

Background:

• Reduced habituation of the nociceptive blink reflex (NBR) is a potential trait marker for migraine genetic predisposition.
• Migraine management often involves prophylactic treatments, but novel therapeutic approaches are needed.

Purpose of the Study:

• To evaluate the efficacy of NBR biofeedback training compared to topiramate and a combination therapy for migraine without aura.
• To assess the impact of NBR biofeedback on headache frequency, disability, and other relevant clinical parameters.

Main Methods:

• An open-label, randomized controlled study involving 33 migraine patients eligible for prophylaxis.
• Patients were assigned to three months of treatment: NBR biofeedback, NBR biofeedback plus topiramate, or topiramate alone.
• Primary outcomes included headache frequency and disability; secondary outcomes encompassed anxiety, depression, sleep, fatigue, quality of life, allodynia, and pericranial tenderness.

Main Results:

• NBR biofeedback treatment reduced headache frequency and disability, similar to topiramate monotherapy and combination therapy.
• While NBR biofeedback did not improve NBR habituation, it did reduce the R2 area.
• No significant differences were observed in most secondary outcome measures between the groups.

Conclusions:

• NBR biofeedback demonstrates efficacy in reducing headache frequency and disability in migraine patients, comparable to established pharmacological treatments.
• The findings suggest that NBR habituation is a stable neurophysiological pattern, but interventions targeting stress responses may modulate migraine pathophysiology.
• NBR biofeedback represents a viable non-pharmacological treatment option for migraine management, potentially by influencing stress-related cortical mechanisms.
