Soft tissue artifact assessment during treadmill walking in subjects with total knee arthroplasty

Kamiar Aminian, Jean-Philippe Thiran, Arnaud Barré

Accurate measurement of knee kinematics during functional activities suffers mainly from soft tissue artifact (STA): the combination of local surface deformations and rigid movement of markers relative to the underlying bone (also called rigid STA movement ...

On-shoe wearable sensors for gait and turning assessment of patients with Parkinson’s disease

Kamiar Aminian, Benoît Mariani

Assessment of locomotion through simple tests such as timed up and go (TUG) or walking trials can provide valuable information for the evaluation of treatment and the early diagnosis of people with Parkinson's disease (PD). Common methods used in clinics a ...

Physical activity recognition via minimal in-shoes force sensor configuration

Kamiar Aminian, Arash Arami, Fabien Massé, Christopher Moufawad El Achkar

We propose a new minimal wearable system and a classifier for physical activity recognition. The configuration is solely based on two force sensors placed anteriorly and posteriorly under the feet. To find the optimal sensor configuration, we estimated the ...

Unraveling dynamics of human physical activity patterns in chronic pain conditions

Kamiar Aminian, Anisoara Ionescu

Chronic pain is a complex disabling experience that negatively affects the cognitive, affective and physical functions as well as behavior. Although the interaction between chronic pain and physical functioning is a well-accepted paradigm in clinical resea ...

Objective evaluation of cervical spine mobility after surgery during freeliving activity

Kamiar Aminian, Cyntia Duc

Background: Evaluation of cervical spine mobility after surgery is mainly based on the measurement of the range of motion during imposed movements. It can thus be questionable if this assessment represents the mobility experienced during daily life. The go ...

Distribution of arm velocity and frequency of arm usage during daily activity: objective outcome evaluation after shoulder surgery

Kamiar Aminian, Alain Farron, Cyntia Duc, Brigitte Jolles-Haeberli

In clinical settings, functional evaluation of shoulder movement is primarily based on what the patient thinks he/she is able to do rather than what he/she is actually performing. We proposed a new approach for shoulder assessment based on inertial sensors ...
