Improving EEG Medical Technology for Black Patients
Addressing Racial Disparities in EEG Design
The medical device industry has historically neglected the specific needs of Black patients, particularly regarding tools like the electroencephalogram (EEG). Standard EEG procedures depend on metal electrodes achieving direct contact with the scalp, a process that is often hindered by coily or curly hair, as well as specific hairstyles like weaves or dreadlocks.
Challenges in Clinical Settings
• Inaccessible Care: Due to a lack of training and equipment design, many technicians struggle to obtain functional EEG readings from Black patients, sometimes leading to frustrated interactions or the improper suggestion to shave a patient's hair.
• Systemic Failure: This problem forces patients and doctors to overcome unnecessary obstacles to secure essential neurological testing, often delaying or preventing accurate diagnoses for conditions like seizures.
Innovative Solutions: Engineering and Education
To bridge this gap, Black scientists and collaborators have developed new, inclusive approaches, proving that biases can be engineered out of medical technology.
Technological Advancements
- Arnelle Etienne’s Innovation: Inspired by a dream, Arnelle developed specialized plastic clips that hold electrodes firmly in place between rows of braided hair. This design improved EEG signal quality by 15 times, turning a previously difficult task into a standard, effective procedure.
Cultural Competence and Education
"If they are exposed to this kind of education, it makes a world of a difference."
- Hairstylist Collaboration: Doctoral student Lietzel Jones teamed up with professional hairstylist Nina Woodley to create a playbook for clinicians. The guide demonstrates how specific hairstyles, such as strategic braiding, can actually enhance electrode contact rather than impede it.
- Reframing Training: By training lab staff on hair care and proper handling techniques, the team fostered a more comfortable and productive environment, reducing the intimidation and lack of knowledge previously felt by technicians.
Overcoming Barriers in Scientific Rigor
Despite the success of these initiatives, innovators face significant pushback from scientific communities that struggle to adapt to new methods or accept anecdotal evidence (such as the impact of hair shrinkage). However, these pioneers are successfully publishing their findings, commercializing new tools, and collaborating internationally, signaling a long-overdue shift in neurological healthcare.
