Background: Flexible flatfeet is a common deformity that affects youngsters and persists throughout their lives, and it is considered to be a contributing factor in many lower limb accidents and low back discomfort. Core muscles function as trunk stabilisers, and any disruption or weakening in these muscles puts a person at risk for low back discomfort and lower limb injury.
Objective: We aimed to compare the core muscles' endurance between adolescents with and without flexible flatfeet.
Patients and Methods: Thirty participants with bilateral flexible flatfeet (study group) were compared with thirty healthy participants (control group). Navicular drop test (NDT) was used to evaluate the medial longitudinal arch. Modified back extensors, modified flexion and lateral muscles' endurance tests were used to evaluate the endurance of the core muscles.
Results: There was no significant difference found in the trunk lateral muscles for left bridge (p = 0.38) and right bridge (p = 0.70) endurance time between both groups.
Conclusion: There is no significant difference in the endurance of the lateral core muscles between adolescents with and without flexible flatfeet at the selected age in the early adolescent stage.
