About this study
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.
- Conditions
- Flexible Flatfoot, Flexible Flatfoot or Pes Planus
- Being tested
- Hip-based Exercise with hot pack and intrinsic foot strengthening exercises, Knee-based exercises with a hot pack and intrinsic foot strengthening exercises
- Medical subject headings
- Flatfoot
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hip-based Exercise with hot pack and intrinsic foot strengthening exercisesProcedure or surgery
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.
Knee-based exercises with a hot pack and intrinsic foot strengthening exercisesProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Group A: Hip-based Exercise with hot pack and intrinsic foot strengthening exercises | Experimental | Not described Receives: Procedure: Hip-based Exercise with hot pack and intrinsic foot strengthening exercises |
| Group B: Knee-based exercises with a hot pack and intrinsic foot strengthening exercises | Active comparator | Not described Receives: Procedure: Knee-based exercises with a hot pack and intrinsic foot strengthening exercises |
What is being measured
The primary outcome is the main question the study is designed to answer.
Lower extremity muscle strength
Digital handheld dynamometer will be used to evaluate improvement in muscular performance associated with each intervention.
Measured: 6 weeks
Secondary outcomes (1)
Medial longitudinal arch height and dynamic balance.
Measured: 6 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Hip-based Exercise with hot pack and intrinsic foot strengthening exercises and Knee-based exercises with a hot pack and intrinsic foot strengthening exercises in people with Flexible Flatfoot and Flexible Flatfoot or Pes Planus, run by University of Faisalabad at 1 site in Pakistan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Dr Izza Ayub; PT Assistant Professor (0330 1980690, drizzaayub@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Lower extremity muscle strength (time frame: 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2026.
