BACKGROUND Increased navicular drop is associated with increased risk of lower extremity overuse injuries and foot orthoses are often prescribed to reduce navicular drop. For laboratory studies, transparent shoes may be used to monitor the effect of orthoses but no clinically feasible methods exist. We have developed a stretch-sensor that allows for in-shoe measurement of navicular drop but the...

BACKGROUND The navicular drop test is a measure to evaluate the function of the medial longitudinal arch, which is important for examination of patients with overuse injuries. Conflicting results have been found with regard to differences in navicular drop between healthy and injured participants. Normal values have not yet been established as foot length, age, gender, and Body Mass Index (BMI)...

[Purpose] The purpose of this study was to determine the relationship between navicular drop and plantar flexion torque of the first and second-fifth metatarsophalangeal joints. [Subjects] Ten healthy young men participated in this study. [Methods] The Pearson product-moment correlation coefficient was calculated to determine the relationship between navicular drop and plantar flexion torque of...

Background: Many research give scatterlly distributed relationship between obesity and the medial longitudinal arch of foot. Among those studies, only two studies have stratified the samples in to underweight, normal weight, overweight and obese groups in the recent past, to explore the relationship of BMI to arch of the foot on the basis of gender variation. Yet these studies contradicted each...

OBJECTIVE The purpose of this study was to examine the relationship between hyperpronation and the occurrence of noncontact injury to the anterior cruciate ligament (ACL). DESIGN AND SETTING Subjects were categorized as either ACL injured (ACLI) or ACL uninjured (ACLU). All ACLI subjects received their injuries from a noncontact mechanism. To justify using the ACLI subjects' uninjured legs as...

abstract introduction: patellofemoral pain syndrome is a common problem in the knee joint, which comprise 20 to 40 percent of knee pain and 10 to 20 percent of subjects admitted in physiotherapy clinics. the aim of this study was to investigate the relationship between navicular drop and tibia torsion in active girl students with and without patellofemoral pain syndrome. materials and methods: ...

Analysis of foot movement is essential in the treatment and prevention of foot-related disorders. Measuring the in-shoe foot movement during everyday activities, such as sports, has the potential to become an important diagnostic tool in clinical practice. The current paper describes the development of a thin, flexible and robust capacitive strain sensor for the in-shoe measurement of the navic...
