Design of the study:~Pretest - posttest randomized controlled trial.~Subjects selection:~Sixty patients their age range from 30-50 years of both genders with chronic plantar fasciitis will participate in this study according to sample size calculation.
The goal of this clinical trial] is to compare between the effect of instrument assisted soft tissue mobilization and positional release technique in patients with chronic plantar fasciitis~The main question[s] it aims to answer are:~Is there a difference between the effect of instrument assisted soft tissue mobilization and positional release technique on pain pressure threshold in patients with chronic plantar fasciitis?~Is there a difference between the effect of instrument assisted soft tissue mobilization and positional release technique on foot function level in patients with chronic plantar fasciitis?
