Application
Design takeaway
Designers should consider the impact of intrinsic foot muscle strength on gait performance, particularly in dynamic situations like faster walking, when developing products for older adults.
How to apply
When designing footwear or mobility aids for older adults, consider how the design can support or compensate for reduced toe flexor strength, especially for activities requiring quicker movements.
Project actions
- 01Consider how the design of a product might affect the user's ability to use their feet and toes for balance and movement.
- 02When testing prototypes with older users, observe their foot placement and how they push off the ground.

Variables
Strengths & Limitations
Strengths
- +Investigated a specific, often overlooked, muscle group.
- +Used objective measurement tools for both strength and gait.
- +Controlled for several potential confounding factors.
Limitations
It's difficult to isolate the effect of toe flexor strength from other factors like balance, overall leg strength, or neurological conditions.
Reliability & validity
The study used standardized instruments for strength measurement and gait analysis, enhancing reliability. The focus on specific gait parameters and controlling for covariates contributes to validity.
Think critically
How might a design intervention that strengthens toe flexors be integrated into everyday products or activities to improve gait in older adults?
Design Principles
"Dynamic gait performance is influenced by the strength of intrinsic foot muscles, especially under increased demand."
This research highlights the critical, yet often overlooked, role of intrinsic foot muscles in maintaining dynamic gait stability and efficiency. For designers, understanding these biomechanical relationships is crucial for developing assistive devices, footwear, and rehabilitation tools that can enhance mobility and reduce fall risk in aging populations.
What This Means for Your Design
If older people have weak toe muscles, they walk slower and take shorter steps when they try to walk fast.
How to use in your project
- 1.Reference this study when discussing the biomechanics of walking and how design can impact mobility in older adults.
- 2.Use the findings to justify design choices related to footwear, assistive devices, or exercise equipment.

Paragraph starter
Research indicates that reduced toe flexor strength in older adults is associated with impaired gait dynamics, specifically slower walking speeds, reduced swing phase duration, and shorter stride lengths during faster ambulation. This highlights the importance of considering intrinsic foot muscle function in the design of products aimed at enhancing mobility and safety for this demographic.
