The Effect of Subtalar Joint Pronation Amount on Lower Extremity Alignment and Performance
Turkey (Türkiye)48 participantsStarted 2023-12-15
Plain-language summary
The lower extremity consists of segments that can be affected by the relative position of each other. Deviation of one segment from its normal alignment in the lower extremity also affects the alignment of other segments. The hip joint can affect the frontal plane alignment from proximal to distal, while the foot and ankle complex can also affect it from distal to proximal. Increased subtalar joint pronation in the kinetic chain from distal to proximal; is associated with decreased dorsiflexion angle and increased frontal plane projection angle. It has been shown that ankle dorsiflexion limitation causes changes in the biomechanics and kinematics of landing after jumping, but no study examining the effect of foot pronation on jump tests has been found in the literature. Since the foot is located at the most distal point and acts as a support base for the kinematic chain, the smallest dynamic change in the foot affects the balance of the whole body. Due to foot pronation, changes in the sole contact surface may make it difficult for the foot to adapt to the ground, balance and postural stabilization may be adversely affected, and an increase in the workload of the muscles around the joint may be observed. In another study, it is mentioned that there is limited evidence about the effect of foot posture on postural stability. Although there are studies in the literature examining the effects of subtalar joint pronation on lower extremity alignment and postural stability, studies need to examine the effects of different subtalar joint pronation amounts on lower extremity alignment, jumping performance, and postural stability. Our study will contribute to the literature with this aspect.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This study looked at how subtalar joint pronation in the foot affects lower body alignment and balance — could my level of foot pronation be contributing to my balance or lower extremity problems, and is that worth assessing?
2Since this trial has already been completed and was measuring postural stability, has your team seen any findings from studies like this that might apply to my specific condition?
3The study focused on things like foot position and how it affects performance further up the leg — are there any movement or gait assessments my care team should do to see if my foot mechanics are affecting my knees, hips, or overall stability?
4Would any interventions related to foot pronation correction — like orthotics, bracing, or targeted physical therapy — be worth trying in my case based on what research like this is showing?
5Are there standard treatments for my balance or lower extremity issue that I should try first before looking into research-based approaches that focus on subtalar joint mechanics?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
