The enhanced paper grip test (EPGT), a simple measure of toe strength, is significantly associated with lower limb push-off force, suggesting its utility in assessing an individual's ability to recover balance and thus their risk of falling. This human factors research insight is drawn from a 2023 study published in The Foot. Using Comparative correlational study with 20 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate the enhanced paper grip test (EPGT) as a simple, non-specialized method to assess a user's potential fall risk, particularly when designing for older adults or individuals with mobility concerns.

Key Findings
- 01Both EPGT techniques were significantly associated with leg press force.
- 02The EPGT technique where the participant's ankle was not supported showed a stronger correlation with leg press force (r = 0.652, p = 0.002) compared to the technique where the ankle was supported (r = 0.623, p = 0.003).
- 03Leg press force is indicative of an individual's ability to recover balance after a slip or trip.
Application
Design takeaway
Incorporate the enhanced paper grip test (EPGT) as a simple, non-specialized method to assess a user's potential fall risk, particularly when designing for older adults or individuals with mobility concerns.
How to apply
When designing products or services for user groups where fall risk is a consideration (e.g., elderly care, rehabilitation equipment), consider using the EPGT as a preliminary assessment tool to understand user limitations.
Project actions
- 01When assessing user capabilities for a design project, consider simple, low-cost tests that can reveal important functional limitations.
- 02If your project involves designing for safety or mobility, explore how basic physical assessments can inform your design choices.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes an accessible and inexpensive testing method (EPGT).
- +Establishes a correlation between a simple test and a more complex biomechanical measure related to fall risk.
Limitations
The EPGT may not capture all aspects of balance and fall risk, as it primarily focuses on plantar flexion strength. Other factors like proprioception, vision, and overall muscle coordination also play significant roles.
Reliability & validity
The study demonstrates good reliability for the EPGT by comparing two valid techniques and finding significant correlations. Validity is supported by the association with leg press force, a measure linked to balance recovery.
Think critically
How might the EPGT be adapted or combined with other simple tests to provide a more comprehensive assessment of fall risk for diverse user groups?
Design Principles
"Accessible biomechanical assessments can provide valuable insights into user capabilities and risks, informing design decisions for safety and usability."
Understanding the biomechanical factors that contribute to balance and fall risk is crucial for designing interventions and products that enhance safety, particularly for vulnerable populations. This research provides a practical, accessible method for assessing a key component of balance.
What This Means for Your Design
A simple test where someone grips a piece of paper with their toes can show how strong their leg muscles are for balancing, which helps predict if they might fall.
How to use in your project
- 1.Use the EPGT as a method to gather quantitative data on user strength relevant to the functionality of your design, especially if it relates to stability or mobility.
