Gait in real world: validated algorithms for gait periods and speed estimation using a single wearable sensor

Mobility concerns most daily tasks (e.g., householding, shopping), affecting life quality. Gait speed, recognized as the sixth vital sign, is a key to characterize mobility. It is also a primary outcome of many clinical interventions. Monitoring gait in un ...

Changes in spatio-temporal gait parameters and vertical speed during an extreme mountain ultra-marathon

Kamiar Aminian, Frédéric Meyer, Grégoire Millet, Mathieu Pascal Falbriard

The aim of the present study was to investigate the effects of altitude and distance on uphill vertical speed (VS) and the main spatio-temporal gait parameters during an extreme mountain ultra-marathon. The VS, stride height (SH) and stride frequency (SF) ...

A Personalized Approach to Improve Walking Detection in Real-Life Settings: Application to Children with Cerebral Palsy

Kamiar Aminian, Anisoara Ionescu, Lena Carcreff, Stéphane Armand

Although many methods have been developed to detect walking by using body-worn inertial sensors, their performances decline when gait patterns become abnormal, as seen in children with cerebral palsy (CP). The aim of this study was to evaluate if fine-tuni ...

MEMS Piezoelectric Accelerometer for Vibration Sensing in Harsh Environments

Bradley James Petkus

This master thesis presents a detailed overview of various MEMS accelerometers used as vibrometers in harsh environments. Commercial and scientific literature accelerometers are compared to determine the best accelerometer for said application. This compar ...

Inertial Three-Operator Splitting Method and Applications

Volkan Cevher, Alp Yurtsever, Cong Bang Vu

We introduce an inertial variant of the forward-Douglas-Rachford splitting and analyze its convergence. We specify an instance of the proposed method to the three-composite convex minimization template. We provide practical guidance on the selection of the ...

Inconsistent relationship between body weight/body mass index prior to total knee arthroplasty and the 12-year survival

Background: The primary hypothesis was that body weight (BW) and body mass index (BMI) significantly impact the long-term survival rate after implantation of a mobile bearing total knee arthroplasty (TKA). Methods: A national, multicentric, retrospective s ...

Implementation of a patient specific model for the calculation of glenohumeral subluxation

Introduction: Total Shoulder Arthroplasty is a well-established surgery for restoring comfort and function to the arthritic shoulder. Among the different surgical options this procedure appears to provide the most rapid and complete reestablishment of the ...

Total hip arthroplasty using a cementless dual-mobility cup provides increased stability and favorable gait parameters at five years follow-up

Kamiar Aminian

Rates of dislocation following primary total hip arthroplasty (THA) vary from 0.5 to 10%. Dual-mobility cups in THA demonstrate increased stability. Clinical outcomes following THA with dual-mobility cups have been reported, but gait has not been assessed. ...

Effect of changes of femoral offset on abductor and joint reaction forces in total hip arthroplasty

Alexandre Terrier, Adeliya Latypova, Hannes Andreas Rüdiger, Maïka Réane Guillemin

Anatomical reconstruction in total hip arthroplasty (THA) allows for physiological muscle function, good functional outcome and implant longevity. Quantitative data on the effect of a loss or gain of femoral offset (FO) are scarce. The aim of this study wa ...

The use of body worn sensors for detecting the vibrations acting on the lower back in alpine ski racing

Kamiar Aminian, Benedikt Fasel

This study explored the use of body worn sensors to evaluate the vibrations that act on the human body in alpine ski racing from a general and a back overuse injury prevention perspective. In the course of a biomechanical field experiment, six male Europea ...
