Is this trial a fit for you?

Likely a good fit

Adults aged 18-65 with unilateral heel pain for at least 3 months and tenderness at the medial calcaneal tubercle.

Probably not a fit

Patients without prolonged heel pain or with excluded conditions may not benefit from study findings.

What this trial studies

This observational study examines how neurophysiological measures (pressure pain threshold and central sensitization), pain intensity, psychological factors (kinesiophobia, catastrophizing, anxiety, and depression), ultrasound findings (plantar fascia thickness), and functional outcomes relate in adults with plantar fasciitis. Researchers will collect data on pain thresholds, pain perception, psychological questionnaires, ultrasound measurements, and functional indices to explore possible associations. The study does not assign treatments but seeks to identify factors that contribute to pain and function in plantar fasciitis. Findings may help clarify the role of central sensitization and psychological factors in this condition. Participant data will be gathered from adults with unilateral heel pain lasting at least 3 months at a single hospital site.

Why it matters

Potential benefit: If successful, the study could improve understanding of non-mechanical contributors to plantar fasciitis and inform more holistic approaches to management.

How similar studies have gone: Previous research has suggested a role for central sensitization and psychological factors in musculoskeletal pain, but data in plantar fasciitis are limited and findings are mixed.
