Tibial nerve size and clinical features in chronic plantar fasciitis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross-sectional observational study uses ultrasound and clinical assessments to explore associations between tibial nerve cross-sectional area at the tarsal tunnel and measures of plantar fascia thickness, pressure pain threshold, foot posture, and functional status in adults with chronic plantar fasciitis. The goal is to see if tibial nerve morphology helps explain why some patients have more pain or disability than would be expected from plantar fascia thickness alone. Findings could inform future prospective research and help identify additional targets for managing chronic plantar fasciitis. The study does not establish causation due to its observational design. Participants will undergo pressure pain threshold testing and bilateral ultrasonographic assessments of the plantar fascia and tibial nerve.
