“…For example, the large number of variants and cut-offs of the Tinetti Test [8] complicates its validation for falls prediction [9]. Moreover, these screening tools are based on subjective analysis requiring the presence of a trained, self-reliant expert [10] and are limited by ceiling effect [11].…”

“…The angles of the major joints of ankle and foot change continuously during walking and those angles can be modified in SolidWorks so that the corresponding joints are reassembled, presenting the model of a new gait phase. The modification of the joints' angles must be within the movement range of the joints to reflect the practical condition [18]. The heel-strike model was obtained by adjusting the angle of the joint of tibia and talus and the joint of fibula and talus in the neutral position model into dorsiflexion 15.…”

The program of treatment and rehabilitation of chronic ankle instability is different according to the impairment degree of lateral ligament of the ankle. The diagnosis methods of lateral ligament's injury are magnetic resonance imaging (MRI) and arthroscopy, which are either invasive or timeconsuming. This study aims to analyze the mapping relation between lateral ligaments' injury and center of pressure (COP) position shift via finite element analysis in order to explore a method that can diagnose lateral ligaments' injury. Two typical finite element method (FEM) bone models of heelstrike and toes-off phase are built according to the gait metrics. The lateral ligament is simulated by adding the spring to the model in the anatomical position and the injury of lateral ligament is simulated by reducing the stiffness of the spring. The contact pressure between the foot and support plate and COP coordinates are analyzed. The displacement of anterolateral shift of COP coordinates is mapped to the injury degree of lateral ligament. This study provides feasibility to diagnose lateral ligament injury by plantar pressure distribution.

Gait is the main locomotion way for human beings as an autonomous decision. Due to the increase in people with walking disabilities, the precision in gait analysis for purposes in clinical diagnosis, sports medicine or biomechanical research for the design of assistive technologies is of special relevance. The literature reports notable contributions in technological developments with diverse applications; and in some cases, algorithms for characterization and gait analysis; however, more studies related to gait kinematics are necessary, such as the solution proposed in this work. In this paper, we focus on studying the forward kinematics of the lower limbs in human gait, using in a novel way quaternions algebra as mathematical tool and comparative analysis with classical methods is established. Gait analysis unlike other works is carried out by evaluating the rotational and tilting movements of the pelvis, flexion-extension of the hip and knee; as well as dorsiflexion and plantarflexion of the ankle. Finally, an assessment of normal, mild crouch and severe crouch gaits in the three anatomical planes is performed; and a metric based on the Euclidean norm in the cartesian space is used to evaluate these gaits.
