An important phase in the step cycle is foot contact. When the moment of foot contact differs from the one expected, a fast response is needed. Such a mismatch can be caused by hitting a support surface earlier or later than expected. To study this, experiments were performed with healthy young adults who walked on a platform that was unexpectedly at a lowered (5 cm) or at a level height. Glass...

The aim of this study was to test the hypothesis that the motion of the soft tissue of the lower leg contributes significantly to the attenuation of the forces during heel impacts. To examine this, a two-dimensional model of the shank and heel pad was developed using DADS. The model contained a heel pad element and a rigid skeleton to which was connected soft tissue which could move relative to...

Plantar heel pain/plantar fasciitis is one of the most common musculoskeletal complaints of the foot. This presentation reviews some of the more important recent findings to update practitioners on the aetiology and diagnosis of plantar heel pain. A critical, narrative review of key findings from recent research that our research group and other investigators have conducted relating to plantar ...

Background The cause of heel pain among soccer players is multifactorial and is related to repetitive microtrauma due to impact forces involving technical moves, but also the playground, the exercise mode, the recovery time, the climatic conditions and the footwear used. Aim To investigate the aetiology of plantar heel pain of soccer players with the objective of proposing an example of guide...

Pain heel constitutes 15% of foot pain. Pain may be caused by plantar fasciitis, calcaneal fractures, calcaneal apophysitis, heel pad atrophy, inflammatory diseases or related with nerve involvement. Tibial, plantar and/or medial nerve entrapment are the neural causes of pain. Most of the heel soft tissue sensation is provided by medial calcaneal nerve. Diagnosis of heel pain due to neural caus...

PURPOSE The aim of this study was to compare the biomechanical changes during natural heel-toe running with learned midfoot and Pose running. METHODS Twenty heel-toe runners were instructed in midfoot running and a novel running style in which the acromium, greater trochanter, and lateral malleolus are aligned in stance (Pose running). Clinical gait analysis was performed for each running sty...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

OBJECTIVE The objectives of this study were to investigate the causes of plantar heel pain and find differences in the clinical features of plantar fasciitis (PF) and fat pad atrophy (FPA), which are common causes of plantar heel pain, for use in differential diagnosis. METHOD This retrospective study analyzed the medical records of 250 patients with plantar heel pain at the Foot Clinic of Re...
