BACKGROUND: Pronated foot is a deformity with various degrees of physical impact. Patients with a pronated foot experience issues such as foot pain, ankle pain, heel pain, shin splints, impaired balance, plantar fasciitis, etc. METHODS: Seventy-two participants between the ages of 18 to 25 years with a flexible pronated foot were included and allocated into three groups: Control, stretching, and IASTM group using single-blinded randomization. Range of motion (ROM) measuring ankle flexibility, foot posture index (FPI), foot function index (FFI), and dynamic balance was measured at baseline and after 4 weeks of intervention. Soft tissue mobilization was applied on to the IASTM group, while the stretching group was directed in static stretching of the gastrocnemius-soleus complex, tibialis anterior, and Achilles tendon in addition to the foot exercises. The control group received only foot exercises for 4 weeks. RESULTS: The result shows the significant improvement of the right dominant foot in ROM plantar flexion, (F = 3.94, p = 0.03), dorsiflexion (F = 3.15, p = 0.05), inversion (F = 8.54, p = 0.001) and eversion (F = 5.93, p = 0.005), FFI (control versus IASTM, mean difference (MD) = 5.9, p < 0.001), FPI (right foot, control versus IASTM MD = 0.88, p = 0.004), and in dynamic balance of the right-leg stance (anterior, pre versus post = 88.55 +/- 2.28 versus 94.65 +/- 2.28; anteromedial, pre versus post = 80.65 +/- 2.3 versus 85.55 +/- 2.93; posterior, pre versus post = 83 +/- 3.52 versus 87 +/- 2.99 and lateral, pre versus post = 73.2 +/- 5.02 versus 78.05 +/- 4.29) in the IASTM group. The FFI was increased remarkably in the stretching group as compared to the control group. CONCLUSIONS: Myofascial release technique, ie, IASTM with foot exercises, significantly improves flexibility, foot posture, foot function, and dynamic balance as compared to stretching, making it a choice of treatment for patients with a flexible pronated foot.
