Gait & Posture > 2017 > 58 > C > 252-260

Gait analysis is recognized as a useful assessment tool in the field of human movement research. However, doubts remain on its real effectiveness as a clinical tool, i.e. on its capability to change the diagnostic-therapeutic practice. In particular, the conditions in which evidence of a favorable cost-benefit ratio is found and the methodology for properly conducting and interpreting the exam are...

Gait & Posture > 2017 > 58 > C > 194-200

Diabetes neuropathy and vasculopathy are the two major complications of diabetes mellitus, leading to diabetic foot disease, of which the worst consequences are plantar ulcers and amputations. Motor impairments like joint stiffness and loss of balance are distinctive effects of diabetes and they have been extensively explored. However, while altered muscle function has been also assessed through experimentally...

Underwater gait analysis in Parkinson’s disease

Daniele Volpe, Davide Pavan, Meg Morris, Annamaria Guiotto, more

Gait & Posture > 2017 > 52 > C > 87-94

Although hydrotherapy is one of the physical therapies adopted to optimize gait rehabilitation in people with Parkinson disease, the quantitative measurement of gait-related outcomes has not been provided yet. This work aims to document the gait improvements in a group of parkinsonians after a hydrotherapy program through 2D and 3D underwater and on land gait analysis. Thirty-four parkinsonians and...

Altered EMG patterns in diabetic neuropathic and not neuropathic patients during step ascending and descending

Fabiola Spolaor, Zimi Sawacha, Gabriella Guarneri, Silvia Del Din, more

Journal of Electromyography and Kinesiology > 2016 > 31 > C > 32-39

Diabetic peripheral neuropathy (DPN) causes motor control alterations during daily life activities. Tripping during walking or stair climbing is the predominant cause of falls in the elderly subjects with DPN and without (NoDPN). Surface Electromyography (sEMG) has been shown to be a valid tool for detecting alterations of motor functions in subjects with DPN. This study aims at investigating the...

Towards the generation of a parametric foot model using principal component analysis: A pilot study

Alessandra Scarton, Zimi Sawacha, Claudio Cobelli, Xinshan Li

Medical Engineering & Physics > 2016 > 38 > 6 > 547-559

There have been many recent developments in patient-specific models with their potential to provide more information on the human pathophysiology and the increase in computational power. However they are not yet successfully applied in a clinical setting. One of the main challenges is the time required for mesh creation, which is difficult to automate. The development of parametric models by means...

Processing of sEMG signals for online motion of a single robot joint through GMM modelization

Riccardo Valentini, Stefano Michieletto, Fabiola Spolaor, Zimi Sawacha, more

2015 IEEE International Conference on Rehabilitation Robotics (ICORR) > 943 - 949

2015 IEEE International Conference on Rehabilitation Robotics (ICORR)

This paper evaluates the use of Gaussian Mixture Model (GMM) trained through Electromyography (EMG) signals to online estimate the bending angle of a single human joint. The parameters involved in the evaluation are the number of Gaussian components, the channel used for model, the feature extraction method, and the size of the training set. The feature extraction is performed through Wavelet Transform...

MOtoNMS: A MATLAB toolbox to process motion data for neuromusculoskeletal modeling and simulation

Alice Mantoan, Claudio Pizzolato, Massimo Sartori, Zimi Sawacha, more

Source Code for Biology and Medicine > 2015 > 10 > 1 > 1-14

Background Neuromusculoskeletal modeling and simulation enable investigation of the neuromusculoskeletal system and its role in human movement dynamics. These methods are progressively introduced into daily clinical practice. However, a major factor limiting this translation is the lack of robust tools for the pre-processing of experimental movement data for their use in neuromusculoskeletal modeling...

3D finite element model of the diabetic neuropathic foot: A gait analysis driven approach

Annamaria Guiotto, Zimi Sawacha, Gabriella Guarneri, Angelo Avogaro, more

Journal of Biomechanics > 2014 > 47 > 12 > 3064-3071

Diabetic foot is an invalidating complication of diabetes that can lead to foot ulcers. Three-dimensional (3D) finite element analysis (FEA) allows characterizing the loads developed in the different anatomical structures of the foot in dynamic conditions. The aim of this study was to develop a subject specific 3D foot FE model (FEM) of a diabetic neuropathic (DNS) and a healthy (HS) subject, whose...

Assessment of biofeedback rehabilitation in post-stroke patients combining fMRI and gait analysis: a case study

Silvia Del Din, Alessandra Bertoldo, Zimi Sawacha, Johanna Jonsdottir, more

Journal of NeuroEngineering and Rehabilitation > 2014 > 11 > 1 > 1-12

Background The ability to walk independently is a primary goal for rehabilitation after stroke. Gait analysis provides a great amount of valuable information, while functional magnetic resonance imaging (fMRI) offers a powerful approach to define networks involved in motor control. The present study reports a new methodology based on both fMRI and gait analysis outcomes in order to investigate the...

Gait & Posture > 2013 > 37 > 4 > 603-610

The aim of this study was to investigate the role of foot morphology, related with respect to diabetes and peripheral neuropathy in altering foot kinematics and plantar pressure during gait. Healthy and diabetic subjects with or without neuropathy with different foot types were analyzed. Three dimensional multisegment foot kinematics and plantar pressures were assessed on 120 feet: 40 feet (24 cavus,...

Integrated kinematics–kinetics–plantar pressure data analysis: A useful tool for characterizing diabetic foot biomechanics

Zimi Sawacha, Gabriella Guarneri, Giuseppe Cristoferi, Annamaria Guiotto, more

Gait & Posture > 2012 > 36 > 1 > 20-26

The fundamental cause of lower-extremity complications in diabetes is chronic hyperglycemia leading to diabetic foot ulcer pathology. While the relationship between abnormal plantar pressure distribution and plantar ulcers has been widely investigated, little is known about the role of shear stress. Moreover, the mutual relationship among plantar pressure, shear stress, and abnormal kinematics in...

Abnormal muscle activation during gait in diabetes patients with and without neuropathy

Zimi Sawacha, Fabiola Spolaor, Gabriella Guarneri, Paola Contessa, more

Gait & Posture > 2012 > 35 > 1 > 101-105

The World Health Organization warns that, in 2000, as many as 33 million Europeans suffered from diabetes, approximately 15% will likely develop foot ulcers, and approximately 15–20% of these patients will face lower-extremity amputation. Changes in some gait parameters that appear to be specific in diabetes have been identified in the literature: shorter stride length, reduced walking speed, and...

Markerless analysis of front crawl swimming

Elena Ceseracciu, Zimi Sawacha, Silvia Fantozzi, Matteo Cortesi, more

Journal of Biomechanics > 2011 > 44 > 12 > 2236-2242

Research on motion analysis of swimmers is commonly based on video recordings of the subject's motion, which are analyzed by manual digitization of feature points by an operator.This procedure has two main drawbacks: it is time-consuming, and it is affected by low repeatability. Therefore, the application of video-based, automatic approaches to motion analysis was investigated. A video-based, markerless...
