Nature as Medicine for the Healing Brain: Utilization of a Nature-based Exposure Intervention for Decreasing Concussion Recovery Timeline and Symptom Load

9. Juni 2026 aktualisiert von: Owen Griffith, Penn State University

The overall goal of this research is to provide pilot data that informs and drives a larger scale research project, incorporating multiple contemporary measurement modalities, to understand the utility and pathological mechanisms by which exposure to nature-based settings may aid in recovery time and symptom relief of individuals suffering from concussion, and decrease their risk of developing Persistent Post-Concussion Syndrome (PPCS).

We hypothesize that successful adherence to a nature-based exposure therapy intervention program will decrease recovery time and severity of symptom trajectory of concussion, as measured through multimodal assessments of brain structural and functional integrity.

Studienübersicht

Detaillierte Beschreibung

This study will use a resting state combined electrophysiological-imaging measure of brain region activation, a blood-based measure of neuroinflammatory protein circulation, and a brief but comprehensive neuropsychological functional assessment to identify recovery status of the brain pre- and post-intervention. Measures will be taken at two pre-determined time intervals following concussion for each participant (1-3 days, 28-30 days) and frame the start and end point of a 4-week nature-based exposure therapy intervention program. The self-administered nature-based exposure therapy intervention will consist of 4 weeks of 120 minutes per week (spread over 3-7 days) of nature-based exposure coupled with a guided environmental awareness prompt list per week (Harries et al., 2025; Leão et al., 2025; White et al., 2019).

The primary aim of this study will be to assess the utility of a nature-based exposure therapy intervention in decreasing symptom severity and timeline of concussion. The intervention will include a multi-week program during which patients will participate in a specified duration of emersion in "nature-based environments". This intervention will inform a low-risk, holistic method for concussion management and may decrease risk of PPCS onset. A multimodal measurement battery will assess structural, functional, and behavioral concussion recovery factors as they relate to the nature-based intervention. Trends in recovery measures will be recorded at pre- and post-intervention, as well as throughout the intervention time period to assess both the feasibility/adherence and efficacy of nature-based exposure on recovery from concussion.
