Brief summary: The human foot is a complex structure, which serves functions such as support and mobility. These functions are accomplished through the deformation of the arch, which is controlled by intrinsic and extrinsic foot muscles. The intrinsic muscles have an important role in dynamic stabilization of the foot due to their structurally short force levers and small diameters. There are many studies reporting that foot intrinsic muscle weakness is directly related to pathologies such as structural or functional toe deformities, pes planus, hallux valgus, plantar fasciitis .Therefore it is essential to evaluate the strength of these muscles in an objective and reliable way.

Detailed description: Two different methods are used in measuring muscle strength via a Hand Held Dynamometer; the "break test" and the "make test" . During these tests, the examiner and subject play opposite roles. During the make test, the subject applies maximal force against the examiner and the position is maintained by the examiner. During the break test, the subject holds the position of the muscle being evaluated and the examiner pushes until the subject's maximal force is overcome. In the two tests, force is applied differently; the dynamometer receives different amounts of force, and different results may be generated. Therefore, the aim of this study was to compare the reliability of intrinsic foot muscle strength assessment with break and make test in healthy young subjects.
