“…Table 1 shows the range of movements for a non-phatological subjects [1]. It has been observed that for a right dominat subject is easier to perform such movements (flexion/extension, supination/pronation, aduction/abduction), in clockwise direction whereas for the left-dominant subject is easier to perform the movements in anti-clockwise direction.…”

Abstract-Ankle movements are complex and play a key role in displacement and manipulation of equipment. This paper presents a novel game-based device to assess the ankle movements. The system is composed by a hemisphere, a smartphone, a software application for the smartphone and another one for the computer. The hemisphere acts as the main interface between the foot and the software application. Through the hemisphere, which acts as a pointer or jositick for the foot, the user guides a pointer through a hexagonal trajectory. This allows assessing the ankle movements. The developed system was tested with 11 subjects. Preliminary result shows the potential of the system.

To determine whether foot structure varies according to the presence and radiographic severity of first metatarsophalangeal joint osteoarthritis (first MTPJ OA). MethodsWeight-bearing dorso-plantar and lateral radiographs were obtained for the symptomatic foot of 185 participants (105 females, aged 22 to 85 years) with clinically diagnosed first MTPJ OA. A validated atlas was used to classify participants as having radiographic first MTPJ OA and to stratified into three categories of severity (none/mild, moderate, severe). Bone length,

The fibularis longus attaches to the base of the first metatarsal at the fibularis/peroneus longus tubercle (FLT/PLT). Theoretically, differences in FLT morphology may reflect changes in the function of the fibularis longus. This study defines the normal limits of the FLT position, orientation, and size in patients with morphologically normal foot anatomy. A retrospective analysis of 131 feet without deformity in 72 patients undergoing weightbearing CT (WBCT) at a single center was conducted. The position and morphology of the FLT was assessed with novel measurements including tubercle‐floor distance, tubercle‐metatarsal angle, and the angle between the floor and a line bisecting the FLT (bisecting angle). Roundness of the FLT was compared to a triangle limiting its shape (triangular ratio), with lower values indicating increasing roundness. We also report relative size of the FLT to the first metatarsal (X/Y ratio), and relative size of the first metatarsal and FLT to the second metatarsal (XY/Z ratio). There were no significant side to side differences for any measurement (p > 0.05). Mean values were: tubercle‐floor distance 28.02 ± 2.63 mm, tubercle‐metatarsal angle 32.7 ± 6.32 degrees, bisecting angle 65.58 ± 6.27 degrees, triangular ratio 0.69 ± 0.04, X/Y ratio 1.13 ± 0.20, and XY/Z ratio 3.44 ± −0.72. Bisecting angle strongly correlated with tubercle‐metatarsal angle (Pearson correlation 0.840, p < 0.001) suggesting FLT rotation occurred independent of foot position. ICC was >0.943 for all measurements. This study reports the morphology of the FLT in individuals with normal feet. This normative data may be used in future studies examining differences between groups of patients with foot pathology, helping us better understand the role of fibularis longus in the development and treatment of foot disorders.
