The purpose of this pilot study is to evaluate whether narrow-band green light filtering glasses improve symptom management and participation in rehabilitation among individuals recovering from traumatic brain injury (TBI). Common post-traumatic symptoms such as photophobia, headaches, difficulty concentrating, anxiety, and sleep disturbances may interfere with engagement in rehabilitation therapies and limit recovery. This study will examine whether use of green light filtering eyewear reduces symptom burden and improves participation in physical, occupational, and speech therapy sessions. Findings will provide preliminary evidence regarding the feasibility and potential clinical utility of green light filtering eyewear as a non-pharmacologic intervention during rehabilitation.
Traumatic brain injury is frequently associated with persistent symptoms including headaches, photophobia, cognitive fatigue, anxiety, and sleep disruption. These symptoms may negatively impact participation in rehabilitation therapies and interfere with functional recovery. Photophobia and headache symptoms are particularly common following TBI and are often exacerbated by indoor lighting and visually stimulating environments. Emerging evidence suggests that exposure to green wavelengths of light may reduce headache severity, improve visual comfort, and decrease neurologic symptom burden in i…
Inclusion Criteria: * Age 18 to 70 years * Diagnosis of mild, moderate or severe TBI * Reports at least one of: photophobia, headach, concentration difficulty, anxiety symptoms · * Able to provide informed consent or consent via legally authorized representative * Sufficient cognitive ability to complete study measures Exclusion Criteria: * Severe visual impairment (low vision, not related to injury) * Active ophthalmologic disease * Severe aphasia preventing participation * Severe cognitive impairment preventing study participation * Current use of therapeutic light-filtering glasses * Med…
Participants will wear narrow-band green light filtering glasses during the intervention period while participating in standard inpatient traumatic brain injury rehabilitation. The glasses are designed to filter selected wavelengths of light and are being evaluated for their potential to reduce symptoms commonly experienced after traumatic brain injury, including headache, photophobia (light sensitivity), dizziness, and cognitive fatigue.
