An interventional study of Conventional and Experimental in Flat Feet, sponsored by Cairo University. Completed at 2 sites in Egypt. Open to participants aged 18 Years to 40 Years. Per ClinicalTrials.gov, last updated 2026-07-14.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
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.
It was proved that Individuals with flexible flat foot have reduced core stability. Thus, core stability must be assessed while treating individuals with flexible flat foot and interventions that address core stability must be included in the treatment of flexible flat foot . It was demonstrated that there was a poorer balance in individual with bilateral flexible flat foot. Therefore, it is recommended to add balance training exercises to traditional physical therapy program in cases of flatfoot patients .
40 Participants of both genders with bilateral flexible flatfoot. will be assigned randomly into 2 equal groups: Group A (control group): will receive conventional therapy. Group B (Experimental group): will receive core training protocol and conventional therapy. Subjects will receive 3 sessions per week for 6 weeks.
Outcome measures:
173 studies on the registry are indexed under Flatfoot; 44 are open to participants now.
This study's enrollment of 40 is close to the median of 40 across 122 interventional studies indexed under Flatfoot.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Control group will receive conventional treatment
Other: Conventional
Study group: will receive core training protocol and conventional therapy.
Other: Conventional · Other: Experimental
patients will receive conventional therapy that include 1. Short foot exercises 2. Towel-curl exercise 3. Heel raise exercise 4. Calf stretch
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
Navicular height
