Trial Summary

What is the purpose of this trial?

Modern footwear has been implicated as a contributor to foot pathology and changes in the biomechanics of gait. In addition to footwear, the investigators propose that the lack of terrain variation may directly contribute to the development of common foot pathologies, resulting from decreased intrinsic foot muscle function. This study will examine the current understanding of terrain variation on foot musculature strength and its possible correlation with structural and functional changes within the foot.

Will I have to stop taking my current medications?

Yes, if you are currently taking any anti-inflammatory medication or medication to control nerve issues, you will need to stop, as these are not allowed for participation in the trial.

How does the Terrain Variation treatment for plantar fasciitis differ from other treatments?

The Terrain Variation treatment for plantar fasciitis is unique because it focuses on altering the walking or running surface to address biomechanical factors, unlike traditional treatments that may focus on medication or physical therapy alone. This approach aims to modify the forces on the foot during movement, potentially reducing the overload on the plantar fascia.12345

Interventions

  • Terrain Variation
Trial Overview The study investigates how walking on different terrains affects foot muscle strength. It will compare the foot musculature of healthy individuals against those with plantar fasciitis to see if terrain variation influences foot structure and function.

Findings from Research

In a study of 113 novice military conscripts over 10 weeks, 71 developed plantar fasciitis, with poorer movement quality and lower femoral anteversion angle identified as significant predictors of the condition.
Higher body mass index and stress levels increased the risk of plantar fasciitis, while prior physical exercise was associated with a reduced risk, highlighting the importance of individual characteristics in the development of this condition.
Predictors of plantar fasciitis in Thai novice conscripts after 10-week military training: A prospective study.Harutaichun, P., Boonyong, S., Pensri, P.[2019]
The study found that factors such as increased time spent standing and walking on hard surfaces, as well as forefoot pronation, significantly increase the risk of developing plantar fasciitis among full-time employees in a manufacturing setting.
Implementing strategies like rotating shoes, using shoe orthoses, and modifying workstations to reduce time on hard surfaces can help prevent or treat plantar fasciitis effectively.
Risk factors for plantar fasciitis among assembly plant workers.Werner, RA., Gell, N., Hartigan, A., et al.[2010]
A study involving 246 young male Army trainees revealed significant variability among clinicians when assessing foot types, indicating a lack of consistent definitions for flat and high-arched feet.
The findings highlight the urgent need for objective standards and quantitative methods to evaluate foot morphology, as current assessments can lead to inconsistent diagnoses and potential implications for injury risk in active individuals.
