A wrist sensor and algorithm to determine instantaneous walking cadence and speed in daily life walking

Kamiar Aminian, Pierre-André Farine, Cyntia Duc, Benedikt Fasel, Martin Savary, Flavien Bardyn, Farzin Dadashi

In daily life, a person’s gait—an important marker for his/her health status—is usually assessed using inertial sensors fixed to lower limbs or trunk. Such sensor locations are not well suited for continuous and long duration measurements. A better locatio ...

Measuring upper limb function in children with hemiparesis with 3D inertial sensors

Kamiar Aminian, Cyntia Duc, Farzin Dadashi, Fabien Massé

Upper limb assessments in children with hemiparesis rely on clinical measurements, which despite standardization are prone to error. Recently, 3D movement analysis using optoelectronic setups has been used to measure upper limb movement, but generalization ...

Heightened clinical utility of smartphone versus body-worn inertial system for shoulder function B-B score

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

The B-B Score is a straightforward kinematic shoulder function score including only two movements (hand to the Back + lift hand as to change a Bulb) that demonstrated sound measurement properties for patients for various shoulder pathologies. However, the ...

Measurement Properties of the Smartphone-Based B-B Score in Current Shoulder Pathologies

Kamiar Aminian, Alain Farron, Cyntia Duc

This study is aimed at the determination of the measurement properties of the shoulder function B-B Score measured with a smartphone. This score measures the symmetry between sides of a power-related metric for two selected movements, with 100% representin ...

Evaluation of the muscular activity duration in shoulders with rotator cuff tear using inertial sensors and electromyography

Kamiar Aminian, Alain Farron, Cyntia Duc

Shoulder disorders, including rotator cuff tears, affect the shoulder function and result in adapted muscle activation. Although these adaptations have been studied in controlled conditions, free-living activities have not been investigated. Based on the k ...

A wearable inertial system to assess the cervical spine mobility: comparison with an optoelectronic-based motion capture evaluation

Kamiar Aminian, Cyntia Duc

In clinical settings, the cervical range of motion (ROM) is commonly used to assess cervical spine function. This study aimed at assessing cervical spine mobility based on head and thorax kinematics measured with a wearable inertial system (WS). Sequences ...

Stride count and frequency measured with a wrist-worn inertial sensor

Kamiar Aminian, Cyntia Duc, Benedikt Fasel

This study proposes three simple approaches to estimate the stride count and frequency during walking and running using an inertial measurement system on the wrist. The approaches were based on a time-domain, frequency-domain and autocorrelation analysis, ...

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 ...
