The aim of this study is to find the effect of a program of corrective kinesiotaping on pain intensity, foot function, and the sonographic picture of plantar fascia in adolescents with pronated feet.This study hypothesizes that there will be a statistically significant effect of a program of application of the corrective technique of kinesiotaping on plantar heel pain, foot function, and the sonographic picture of plantar fascia in a sample of Egyptian adolescents suffering from pronated feet.

This study will be conducted to find the effect of a program of corrective kinesiotaping on pain intensity, foot function, and the sonographic picture of the plantar fascia in adolescents with pronated feet. Thirty adolescents suffering from plantar heel pain associated with pronated feet will be included in this study. They will be distributed randomly into 2 groups: Group A will receive corrective kinesiotaping (50-75% stretch) for 6 weeks, 2 times per week with 1 day of rest; Group B will receive a home program of intrinsic foot strengthening and stretching exercises. Data will be collected pre- and post-intervention for all groups by using the visual analog scale (VAS), the first two subscales of the foot function index (FFI), and a sonographic picture of the foot for each adolescent. Participants will be recruited from outpatient clinics and schools.

Inclusion Criteria:

• Children with unilateral or bilateral plantar fasciitis.
• pronated foot or foot on weightbearing in the navicular drops test.

Exclusion Criteria:

• Corticosteroid injection of the heel within the past 3 months.
• Posterior heel pain.
• Systemic inflammatory conditions.
• Diabetes.
