Individuals with plantar fasciitis exhibit reduced accuracy in sensing ankle joint position and diminished postural stability, with pain catastrophizing significantly predicting these deficits. This human factors research insight is drawn from a 2025 study published in Journal of Orthopaedic Surgery and Research. Using Cross-sectional study with advanced biomechanical and psychosocial correlates. with 126 participants (63 with plantar fasciitis, 63 controls), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for individuals with plantar fasciitis, prioritize interventions and products that actively enhance ankle joint position sense and postural stability, while also considering psychological factors like pain perception.

Plantar Fasciitis Impairs Ankle Proprioception and Postural Control, Exacerbated by Pain Catastrophizing

Individuals with plantar fasciitis exhibit reduced accuracy in sensing ankle joint position and diminished postural stability, with pain catastrophizing significantly predicting these deficits.

Key Findings

  • 01Plantar fasciitis patients showed significantly higher AJPS error in plantarflexion and dorsiflexion compared to controls.
  • 02Pain catastrophizing was a significant predictor of AJPS accuracy in plantarflexion.
  • 03Postural stability was negatively correlated with AJPS accuracy, particularly in the mediolateral direction.

Application

Design takeaway

When designing for individuals with plantar fasciitis, prioritize interventions and products that actively enhance ankle joint position sense and postural stability, while also considering psychological factors like pain perception.

How to apply

When designing rehabilitation equipment or footwear for individuals with foot and ankle conditions, integrate elements that provide clear sensory feedback and actively challenge or support postural control.

Project actions

  • 01Consider how sensory feedback (like touch or pressure) can be used to improve user awareness of body position.
  • 02Explore how different materials or shapes can influence stability and balance in a product design.

Method & Evidence

AimTo investigate the relationship between ankle joint position sense (AJPS) accuracy, postural stability, lower limb muscle strength, gait parameters, and psychosocial factors in individuals with plantar fasciitis.
MethodCross-sectional study with advanced biomechanical and psychosocial correlates.
ProcedureParticipants with and without plantar fasciitis underwent assessments of AJPS using a digital inclinometer, postural stability via computerized posturography, muscle strength with a hand-held dynamometer, gait parameters using 3D motion capture, and psychosocial factors through validated questionnaires.
Sample126 participants (63 with plantar fasciitis, 63 controls)
ContextOrthopaedic surgery, physical medicine and rehabilitation, physical therapy, and biomechanics.

Variables

IV["Presence of plantar fasciitis","Pain catastrophizing levels"]
DV["Ankle joint position sense (AJPS) accuracy","Postural stability metrics (antero-posterior and medio-lateral sway)"]
CV["Age","Sex","Physical activity level","Quality of life"]

Strengths & Limitations

Strengths

  • +Inclusion of a wide range of biomechanical and psychosocial factors.
  • +Use of validated measurement tools and questionnaires.

Limitations

A cross-sectional study can show a link, but it can't prove that plantar fasciitis *causes* the balance problems; it's just that they happen at the same time. Other factors might be involved.

Reliability & validity

The study uses validated questionnaires and established biomechanical measurement techniques, contributing to the reliability and validity of its findings. The cross-sectional design, however, limits the establishment of causal validity.

Think critically

How might the design of everyday objects, such as stairs or flooring, be improved to better support individuals with impaired proprioception and postural control?

05

Design Principles

"Proprioceptive feedback and postural stability are fundamental to safe and efficient movement; impairments in these areas require targeted compensatory or rehabilitative design solutions."

This research highlights a critical link between a common musculoskeletal condition and fundamental human factors like proprioception and balance. Understanding these impairments is essential for designing effective rehabilitation programs and assistive devices that address not only the physical symptoms but also the psychological impact on user performance and well-being.

06

What This Means for Your Design

If someone has plantar fasciitis (pain in the bottom of their foot), they're not as good at knowing where their ankle is or keeping their balance. How much they worry about their pain makes this even worse.

How to use in your project

  • 1.Use this research to justify the need for specific ergonomic features in your design that aim to improve balance or sensory feedback for users with similar conditions.

Paragraph starter

Research indicates that conditions like plantar fasciitis can significantly impair ankle joint position sense and postural control, with psychological factors such as pain catastrophizing playing a predictive role. This suggests that design interventions aimed at improving functional performance for affected individuals should not only address biomechanical deficits but also consider the user's perceptual and emotional state to ensure comprehensive support and rehabilitation.
