The aim of this study is to evaluate the effects of local corticosteroid injection on pain, foot function index, and plantar fascia thickness in patients clinically diagnosed with plantar fasciitis, and to determine whether local corticosteroid injection is an appropriate treatment option for plantar fasciitis. For this purpose, the study plans to assess plantar fascia thickness using ultrasonography, evaluate pain using the Visual Analog Scale (VAS), and investigate the impact on daily living activities in patients who have been clinically diagnosed with plantar fasciitis and treated with local corticosteroid injections.

Inclusion Criteria:

• Patients who were clinically diagnosed with plantar fasciitis and received corticosteroid injections

Exclusion Criteria:

• Pregnancy
• Patients who have had more than one corticosteroid injection in the last 6 months
• Patients with systemic inflammatory diseases
• Patients who have previously undergone surgery in the heel area
• Patients with a history of local trauma

33 patients who volunteered to participate in the study and applied to the Physical Medicine and Rehabilitation Clinic of the SBÜ Istanbul Physical Therapy and Rehabilitation Education and Research Hospital and were diagnosed with plantar fasciitis clinically and received local corticosteroid injections will be included in the study.
