Brief Summary

There is a gap of literature about the role of core stability exercises on management of flexible flatfoot, as a result this study will take a deeper look on the effect of core stability exercises on navicular height, Arch height index, balance and disability function of ankle joint in individuals with bilateral flexible flat foot.

Conditions

Flat Feet

Keywords

core stability exercises; medial longitudinal arch height; balance; bilateral flexible flat foot

Outcome Measures

Primary Outcomes (2)

• Navicular height

  at enrollment and at the end of 6 weeks of treatment

• Balance

  Dynamic balance will be assessed by Biodex system

  at enrollment and at the end of 6 weeks of treatment

Secondary Outcomes (2)

• Medial longitudinal arch height

  at enrollment and at the end of 6 weeks of treatment

• Function of ankle joint

  at enrollment and at the end of 6 weeks of treatment

Other: Conventional; Other: Experimental

Interventions

Conventional OTHER

patients will receive conventional therapy that include 1. Short foot exercises 2. Towel-curl exercise 3. Heel raise exercise 4. Calf stretch

Control group; Study group

Experimental OTHER

Core stability exercises: The training programs will last 6 weeks and comprise 3 training sessions per week. Each training session lasted 30 min, starting with a brief, standardized warm-up program mainly consisting of low-intensity core strength exercises to prepare the neuromuscular system for the training loads and ending with a cool-down program (i.e., dynamic stretching). During the main part of training, research group will conduct the "big 3" exercises as described by McGill (Mcgill, 2001). These include the curl-up, side bridge, and quadruped position. In other words, every single training session consisted of frontal, dorsal, and lateral core exercises. Training intensity will be progressed and individually increased over the 6-week training program by modulating lever lengths, movement velocity
