Neurofeedback Therapy for Sensory Over-Responsiveness-A Feasibility Study

Area of Science:

• Neuroscience
• Psychology

Background:

• Sensory over-responsivity (SOR) is linked to pain hypersensitivity, anxiety, and impaired daily function.
• Reduced cortical activity in SOR suggests neuromodulation as a potential therapy.
• This study explored the feasibility of neurofeedback for individuals with SOR.

Purpose of the Study:

• To investigate the feasibility of neurofeedback intervention for sensory over-responsivity (SOR).
• To assess the impact of neurofeedback on brain activity and behavioral outcomes in SOR.

Main Methods:

• Feasibility study with 10 healthy women exhibiting SOR.
• Intervention involved 10 sessions of neurofeedback targeting alpha oscillatory power upregulation.
• Measures included resting-state EEG, life satisfaction, goal attainment, pain sensitivity, and anxiety assessments at four time points.

Main Results:

• No significant changes were observed between baseline and pre-intervention.
• Post-intervention and follow-up revealed enhanced power in delta, theta, beta, and gamma bands in the frontal region (p = 0.03−<0.001).
• Significant improvements were noted in life satisfaction (Cohen’s d = 1.18), goal attainment (Cohen’s d = 1.04), reduced pain sensitivity (Cohen’s d = 0.70), and anxiety.

Conclusions:

• Neurofeedback intervention is feasible for individuals with sensory over-responsivity.
• The intervention demonstrated significant improvements in cognitive and emotional well-being.
• This study provides a foundation for future research into neurofeedback for SOR.
