Background: One of the most prevalent foot conditions is plantar fasciitis, which causes heel discomfort and can negatively affect a patient's overall and foot-specific health. Patients with this condition also tend to be less socially connected and have low energy levels to engage in activities. Purpose: To assess the effectiveness of a therapeutic exercise program on functional abilities and pain among patients with plantar fasciitis. Methods: A total of 62 individuals suffering from plantar fasciitis were included. Patients were allocated randomly into two equal groups; the study group and the control group. Design: A quasi experimental. Instruments: An organized demographic and Medical Data Sheet, Numerical Pain Rating Scales (NPRS). Foot Functional Index (FFI) and the American Orthopedic Foot and Ankle Society Scale (AOFAS). Results: After the intervention, there was a statistically significant difference between the two groups in favor of the study group for the NPRS score (P value =  0.0001), FFI score (P value = 0.000), and AOFAS score (P value = 0.000). Conclusion: The therapeutic exercise program reduces discomfort and improves foot function abilities in patients with plantar fasciitis. Recommendations: For individuals with plantar fasciitis, the exercise therapy program needs to be promoted as one of the key strategies for managing pain and improving foot functions.
