Knee Implant Loosening Detection: A Vibration Analysis Investigation

Kamiar Aminian, Hossein Rouhani, Arash Arami

Knee implant loosening is mainly caused by the weakness of the prosthesis-bone interface and is the main reason for surgical revisions. However, pre-operative diagnosis is difficult due to lack of accurate tests. In this study, we developed a vibration-bas ...

Sagittal plane blocade in patients with Functional Hallux Limitus:a multisegment model analysis of the Flexor Hallucis Longus endoscopic tenolysis

Kamiar Aminian, Hossein Rouhani, Arash Arami

Functional Hallux Limitus (FHL) is a relatively unknown clinical entity in which dorsal flexion of the first metatarsophalangeal joint is restricted during final stance phase, derailing the three mechanisms of foot stabilization 1. The close packing of the ...

A Wearable System for Multi-Segment Foot Kinetics Measurement

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

This study aims to design a wearable system for kinetics measurement of multi-segment foot joints in long-distance walking and to investigate its suitability for clinical evaluations. The wearable system consisted of inertial sensors (3D gyroscopes and 3D ...

Quantitative estimation of foot-flat and stance phase of gait using foot-worn inertial sensors

Kamiar Aminian, Hossein Rouhani, Benoît Mariani, Xavier Crevoisier

Time periods composing stance phase of gait can be clinically meaningful parameters to reveal differences between normal and pathological gait. This study aimed, first, to describe a novel method for detecting stance and inner-stance temporal events based ...

A Comparison Between Joint Coordinate System and Attitude Vector for Multi-segment foot Kinematics

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

The joint angles of multi-segment foot models have been primarily described using two mathematical methods: the joint coordinate system and the attitude vector. This study aimed to determine whether the angles obtained through these two descriptors are com ...

Measurement of Multi-segment Foot Joint Angles During Gait Using a Wearable System

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

Usually the measurement of multi-segment foot and ankle complex kinematics is done with stationary motion capture devices which are limited to use in a gait laboratory. This study aimed to propose and validate a wearable system to measure the foot and ankl ...

Ambulatory measurement of ankle kinetics for clinical applications

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

This study aimed to design and validate the measurement of ankle kinetics (force, moment, and power) during consecutive gait cycles and in the field using an ambulatory system. An ambulatory system consisting of plantar pressure insole and inertial sensors ...

Segmentation of Foot and Ankle Complex based on Kinematic Criteria

Kamiar Aminian, Julien Favre, Hossein Rouhani, Brigitte Jolles-Haeberli, Xavier Crevoisier

Although various foot models were proposed for kinematics assessment using skin makers, no objective justification exists for the foot segmentations. This study proposed objective kinematic criteria to define which foot joints are relevant (dominant) in sk ...

Outcome evaluation of ankle osteoarthritis treatments: Plantar pressure analysis during relatively long-distance walking

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

Background: This study aimed to use plantar pressure analysis in relatively long-distance walking for objective outcome evaluation of ankle osteoarthritis treatments, i.e., ankle arthrodesis and total ankle replacement. Methods: Forty-seven subjects in fou ...

Ambulatory Assessment of Foot Kinematics and Kinetics : Outcome Evaluation of Ankle Osteoarthritis Treatments

Hossein Rouhani

Two surgical treatments exist for ankle osteoarthritis (AO): ankle arthrodesis (AA) and total ankle replacement (TAR). Due to advantages and drawbacks of each treatment, decision making about these treatments is still a clinical question and thus, their ou ...

Ambulatory Assessment of 3D Ground Reaction Force using Plantar Pressure Distribution

Kamiar Aminian, Julien Favre, Hossein Rouhani, Xavier Crevoisier

This study aimed to use the plantar pressure insole for estimating the three-dimensional ground reaction force (GRF) as well as the frictional torque (T-F) during walking. Eleven subjects, six healthy and five patients with ankle disease participated in th ...
