The objective of this paper is to develop an analytical framework to representing the ankle-foot kinematics by modelling the foot as a rollover rocker, which cannot only be used as a generic tool for general gait simulation but also allows for case-specific modelling if required. Previously, the rollover models used in gait simulation have often been based on specific functions that have usuall...

Purpose Limited research exists regarding use of Astym® therapy with neurologic conditions. The purpose of this case was to describe using Astym therapy in treating spastic diplegic cerebral palsy (CP). Case description A 6-year-old female was treated more than 9 months (36 sessions) for decreased flexibility, muscle weakness, spasticity, and abnormal gait. Examination findings Gait perform...

Inverse dynamics simulation is often used in robotic and mechatronic systems to track a desired trajectory by feed-forward control. Musculoskeletal multibody systems found in biomechanics are highly overactuated due to the many muscles, and they show a switching number of closed kinematical loops. The method of inverse dynamics is also successfully applied to overactuated systems by parameter o...

The purpose of our study was to evaluate all contact pressures between the molded ankle-foot orthosis (MAFO) and the subject during activities of daily living. The MAFOs studied are used clinically to reduce plantar contact pressures associated with foot ulcers in adult neuropathic diabetic subjects, alleviating abnormal pressures by redistributing them to low-pressure plantar regions. While ef...

BACKGROUND Fatigue in combination with gait and balance impairments can severely limit daily activities in people with multiple sclerosis (PWMS). Generalised fatigue has a major impact on walking ability, with moderately disabled PWMS experiencing difficulty in walking extended distances. Localised motor fatigue in the ankle dorsiflexors can lead to foot drop, further reducing functional ambula...

The main task of orthoses in neurological diseases is stabilization, correction and improvement gait function. Orthoses actively support the work muscles by proper alignment individual body segments relation to each other facilitate performance planned During upright standing, orthosis keep upper ankle a fixed, intermediate position, usually at an angle 90°. This increases base provided feet fl...

BACKGROUND Rollover footwear is assumed to provide an enhanced surface over which the body can roll more easily. The aim of this study was to investigate the effects of rollover footwear on the rollover function of walking. METHODS Twenty subjects walked in three conditions: (i) a MBT shoe (Masai Barefoot Technology) characterized by a stiff sole rounded in the anterior-posterior direction; (...
