Pressure Pain Threshold Assessment: Pressure pain threshold measurements will be performed using a pressure algometer to assess pain sensitivity.
Ultrasonographic Assessment: Ultrasonographic evaluation will be performed to measure plantar fascia thickness and assess plantar fascia morphology.
Study summary
Plantar fasciitis is a common cause of heel pain and is traditionally considered a mechanical musculoskeletal disorder. Recent evidence suggests that central sensitization may also contribute to pain in individuals with plantar fasciitis. This study aims to investigate the relationships between neurophysiological variables (pressure pain threshold, central sensitization, and pain intensity), psychological factors (pain catastrophizing, kinesiophobia, anxiety, and depression), ultrasonographic findings (plantar fascia thickness), and functional outcomes (foot function and quality of life) in patients with plantar fasciitis.

Primary outcome measure(s)
Forearm Pressure Pain Threshold (PPT) — Baseline Pressure pain threshold is defined as the minimal pressure level that causes pain. The measurement will be applied twice for each region with a 1-minute interval, and the average of these applications will be recorded. A trial test will be conducted on the patient before the actual test. Pressure will be applied to selected points with a pressure algometer until pain is induced, and the test for that area will be terminated when the patient feels pain.
The measurement will be taken from the calcaneus bone (the starting point of the plantar fascia) and from the forearm, which is a distant, painless, and unrelated area, using the Wagner manual pressure algometer (1 cm² probe-10 kg/20 lb). The reliability of the measurement in these areas has been demonstrated.
