In order to improve the understanding foot function in the presence of planovalgus foot deformity, functional joint center determination is applied to the ankle and midfoot for application in 3D-gait analysis. Gait data of 36 patients with planovalgus (PV) foot deformity as well as of 33 typically developing (TD) subjects were collected using foot markers according to the Heidelberg Foot Measurement method. During single-limb stance subjects performed a circular movement of the foot and ankle (CIR) by drawing a circle with the hallux in the air.

Background: Intrinsic foot muscle weakness has been implicated in a wide range of forefoot conditions and is typically measured by the paper grip test. The proposed "knuckle test" is intended to evaluate intrinsic foot muscle function, in which active flexion of toes makes the metatarsal heads ("knuckles") prominent in the forefoot. This study seeks to compare prevalence of negative knuckle test results and intrinsic muscle weakness in patients, primarily by association with a positive paper grip test result and secondarily with presence of toe deformities.

To analyze the distribution characteristics of foot deformities and the biomechanical features of the feet among elderly diabetic patients in the community. A total of 3 148 elderly diabetic patients (6 296 feet) who participated in the diabetic foot screening program in Jinshan District, Shanghai, from March to May 2023 were included, with 1 357 males and 1 791 females, aged (70.7±6.

The aim of the study was to verify relationships between isolated and grouped clinical conditions (Type 2 Diabetes Mellitus [T2DM] and Peripheral Arterial Disease [PAD]) with the skin temperature of the plantar region of the feet (Tskin_Feet). Twenty-four elderly women participated, divided into three groups: GT2DM + PAD (n = 8; 69.6 ± 8.

Background: Morton neuroma is a common cause of forefoot pain and sensory disturbances, but it is difficult to identify on magnetic resonance imaging (MRI). The aim of this study was to verify the usefulness of a characteristic MRI finding (slug sign) for identifying Morton neuroma and to clarify the relationship between excised neuroma characteristics and preoperative MRI findings.
Methods: Twenty-two web spaces were retrospectively assessed from the second and third intermetatarsal spaces of 11 feet of 10 patients (7 women and 3 men, aged average 59.
