The goal of this observational study is to explore potential associations between baseline patient characteristics (such as age, body mass index, and baseline pain intensity) and clinical outcomes in patients with plantar fasciitis undergoing radial pressure wave therapy (RPWT). The study includes male and female adults aged 18 to 60 years.

Background: Plantar fasciitis (PF) is a common cause of heel pain, significantly impairing functionality and quality of life. Radial pressure wave therapy (RPWT) has emerged as a non-invasive therapeutic option. However, there is limited evidence regarding factors that may influence clinical outcomes in patients receiving this treatment.

Objectives: The primary objective of this study is to explore potential associations between baseline patient characteristics (such as age, body mass index, and pain intensity) and clinical outcomes in patients with PF treated with RPWT. Additionally, this study aims to assess changes in pain intensity and functionality following RPWT.

Materials and Methods: This is an exploratory, pilot observational study including patients diagnosed with PF who undergo three sessions of RPWT. The study evaluates changes in pain intensity, assessed using the Numerical Pain Rating Scale (NPRS), and functionality, measured using the WHODAS 2.0. Patient characteristics such as age, body mass index (BMI), and PF chronicity are collected retrospectively from medical records. Statistical analyses will be conducted to examine potential associations between patient characteristics and treatment outcomes.

Inclusion Criteria:

• Diagnosis of plantar fasciitis confirmed by clinical evaluation.
• Age 18 to 60 years.
• Symptoms persisting for at least three months before treatment.
• Completed three RPWT sessions using a standardized protocol (2000 impulses per session, 10 Hz, and 3.5 bar).
• Availability of complete medical records, including three-month follow-up data.

Exclusion Criteria:

• History of foot surgery or corticosteroid injection in the affected limb within the past six months.
• Pregnancy at the time of treatment.
• Presence of concurrent musculoskeletal conditions (e.g., fractures, active infections, sprains) in the affected limb.
• Diagnosis of systemic conditions (e.g., cancer, osteoporosis, autoimmune diseases).
• Incomplete medical records or failure to complete RPWT sessions and follow-up visits.

This study focuses on adult patients diagnosed with plantar fasciitis (PF), a condition commonly affecting middle-aged individuals. Eligible participants are between 18 and 60 years old and present with symptoms persisting for at least three months before treatment. Given that risk factors such as body mass index (BMI) and physical activity levels may influence clinical outcomes, these characteristics will be documented for all participants. Additionally, data on prior conventional physical therapy and PF chronicity (acute vs. chronic cases) will be collected to explore potential associations with treatment response.
