An observational study in Chronic Ankle Instability, sponsored by Cairo University. Completed at 1 site in Egypt. Open to participants aged 15 Years to 32 Years. Per ClinicalTrials.gov, last updated 2025-08-13.
Sponsored by Cairo University · Observational
The purpose of the study is to identify if there is a relationship between the frontal plane projection angle as a measure of dynamic knee valgus with foot posture, pain, and dynamic balance in chronic ankle instability patients.
The study design is an observational, correlational study to find if there is any relationship between the frontal plane projection angle with foot posture, pain, and dynamic balance in chronic ankle instability non-athletic patients.
The sample size is estimated to be 84. The frontal plane projection angle will be measured using a single-leg squat test and analyzed using Kinovea software.
Foot posture will be measured using the foot posture index. pain will be measured using a numerical rating scale. dynamic balance will be measured using modified star excursion balance tets
Cairo University is the lead sponsor of 4,780 studies on the registry; 1,427 are open to participants now.
Of its 36 completed or terminated interventional studies of FDA-regulated products, 5 (14%) have results posted.
Counted across the registry records on this site, refreshed daily.
The sample will be recruited from the outpatient clinic of the Faculty of Physical Therapy at Cairo University by referral from the orthopedic doctor diagnosed with chronic ankle instability.
Exclusion Criteria:
correlation between the frontal plane projection angle and foot posture in chronic ankle instability patients.
NAME OF THE MEASUREMENT: "Frontal Plane Projection Angle" UNIT OF MEASURE: "measured in degrees" MEASUREMENT TOOL: "using a digital camera and Kinovea software" regarding foot posture: NAME OF THE MEASUREMENT: "Foot Posture" MEASUREMENT TOOL: "assessed using the Foot Posture Index (FPI), a 6-item scale" Criteria assessed included palpating the talar head, assessing supra and infra lateral malleolar curvature, calcaneal inversion/eversion, and examining talo-navicular prominence. Additionally, the congruence of the medial longitudinal arch and the forefoot's abduction/adduction relative to the rearfoot was evaluated UNIT OF MEASURE: "scored from -12 to +12 * Highly supinated foot scores between (-5 to -12) * Supinated foot scores between (-4 to -1) * Normal foot scores between (0 to +5) * Pronated foot scores between (+6 to +9) * Highly pronated foot scores between (+10 to +12).
Time frame: baseline (single assessment session)
