Removing artificial barriers and incorporating natural elements in architectural thresholds can eliminate freezing of gait episodes for individuals with Parkinson's disease. This human factors research insight is drawn from a 2015 study published in International Journal of Environmental Research and Public Health. Using Multi-method single-subject study with 5 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate natural, unobstructed pathways and avoid artificial thresholds like doorframes in environments for individuals with Parkinson's disease to prevent freezing of gait.
Biophilic design elements reduce freezing of gait in Parkinson's patients by 100%

Key Findings
- 01No participants experienced FOG when passing through hedge openings without built elements.
- 02FOG was triggered in participants when a doorframe was inserted into a hedge opening.
- 03FOG was also triggered when peripheral vision was blocked at the threshold.
Application
Design takeaway
Incorporate natural, unobstructed pathways and avoid artificial thresholds like doorframes in environments for individuals with Parkinson's disease to prevent freezing of gait.
How to apply
When designing spaces for public access, healthcare facilities, or residential areas for the elderly or those with neurological conditions, opt for naturalistic openings and clear sightlines at doorways and transitions.
Project actions
- 01When researching user needs, consider how the physical environment can trigger or alleviate specific physical or psychological responses.
- 02Explore how natural elements can be integrated into design solutions for accessibility and well-being.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized a multi-method approach combining qualitative and quantitative data.
- +Focused on a specific and impactful user experience (FOG).
Limitations
The small sample size limits the generalizability of the findings. The specific design of the 'hedge opening' and 'doorframe' might also influence the results.
Reliability & validity
The single-subject design with multiple data collection methods (interviews, observations, accelerometers) enhances the internal validity for each participant. However, the small sample size limits external validity and generalizability. Reliability would depend on consistent application of observation criteria and accelerometer data processing.
Think critically
How might the psychological fear of 'getting stuck' at a threshold be exacerbated by the visual cues of artificial structures, and how can design mitigate this?
Design Principles
"Biophilic thresholds promote unimpeded movement and reduce physiological freezing responses."
This research highlights the profound impact of environmental design on physiological responses, particularly for vulnerable populations. Understanding how natural elements interact with human movement and cognitive processes can inform the creation of more supportive and accessible spaces.
What This Means for Your Design
Making doorways look more like natural openings in hedges, without actual doors or frames, can stop people with Parkinson's disease from freezing up when they try to walk through them.

Paragraph starter
Research by Ottosson et al. (2015) indicates that naturalistic thresholds, such as openings in hedges without artificial elements, completely prevented freezing of gait in individuals with Parkinson's disease. In contrast, the introduction of a doorframe or the obstruction of peripheral vision at these openings triggered freezing episodes. This suggests that biophilic design principles, focusing on natural transitions and unobstructed pathways, can significantly enhance mobility and reduce adverse physiological responses in vulnerable user groups.
