Study summary

This study aims to compare the effects of hip-based and knee-based exercise interventions on medial longitudinal arch height, dynamic balance, and lower limb muscle strength in individuals with flexible flat feet. Participants will be randomly assigned to two groups: one receiving hip-focused strengthening and stretching exercises, and the other receiving knee-focused exercises, while both groups will perform a common set of foot intrinsic exercises. The intervention will be conducted over 6 weeks. Outcomes will be measured pre- and post- intervention and in the middle of intervention to determine which approach is more effective in improving foot stability and functional performance.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Give verbal or written consent to enter the study.
  • People without any pain and in the age group of about 25-40 years.
  • People in the category of normal to obese .
  • People whose value of navicular drop above 10mm.

Exclusion criteria

Exclusion Criteria:

  • People having any surgical procedure on the lower limb.
  • People using any kind of orthosis.
  • If the difference between the length of both legs is more than 1.1cm.
  • People having any disease like diabetes, rheumatoid arthritis, plantar fasciitis or sciatica.
  • People having any injury within 6 months.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

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.

    Procedure: Hip-based Exercise with hot pack and intrinsic foot strengthening exercises

  • Active comparator
    Group B: Knee-based exercises with a hot pack and intrinsic foot strengthening exercises

    Procedure: Knee-based exercises with a hot pack and intrinsic foot strengthening exercises

Interventions

  • ProcedureHip-based Exercise with hot pack and intrinsic foot strengthening exercises

    Baseline: Hot pack will be applied to the calf muscle for 5-10 minutes. Then the calf muscles will be stretched with 5 repetitions. Treatment: Clamshell exercises with 4 progressions with 5-10 repetitions and iliopsoas stretching with 3 repetitions per session.

  • ProcedureKnee-based exercises with a hot pack and intrinsic foot strengthening exercises

    Baseline: Hot pack will be applied to the calf muscle for 5-10 minutes. Then the calf muscles will be stretched with 5 repetitions. Treatment: Knee isometrics with 5-1o repetitions along with hamstring stretching 3 repetitions per session.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2026 (actual). Primary completion is estimated for Jun 2026, 3 months after the start.

Of 89 non-industry interventional studies with no phase under Flatfoot, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 15. This study's planned 3 months is below that.

Counting every sponsor, half of 89 studies reached it within 7 months; a quarter within 2 and three quarters within 15.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
