A Novel Approach to Reducing Number of Sensing Units for Wearable Gait Analysis Systems

Kamiar Aminian, Arash Salarian, Brigitte Jolles-Haeberli

Gait analysis methods to estimate spatiotemporal measures, based on two, three or four gyroscopes attached on lower limbs have been discussed in the literature. The most common approach to reduce the number of sensing units is to simplify the underlying bi ...

iTUG, a Sensitive and Reliable Measure of Mobility

Kamiar Aminian, Arash Salarian

Timed Up and Go (TUG) test is a widely used clinical paradigm to evaluate balance and mobility. Although TUG includes several complex subcomponents, namely: sit-to-stand, gait, 180 degrees turn, and turn-to-sit; the only outcome is the total time to perfor ...

Analyzing 180 degrees turns using an inertial system reveals early signs of progression of Parkinson's disease

Kamiar Aminian, Arash Salarian

Changes in turning are one of the early motor deficiencies in Parkinson's Disease (PD). We have proposed a system based on wearable, inertial sensors and a novel automatic analysis algorithm that can assess 180 degrees turns. Twelve patients in early stage ...

Kinematics and dynamic complexity of postural transitions in frail elderly subjects

Kamiar Aminian, Anisoara Ionescu, Arash Salarian, Raluca Lidia Ganea

The aim of this study was to propose a methodology allowing a detailed characterization of body sit-to-stand/stand-to-sit postural transition. Parameters characterizing the kinematics of the trunk movement during sit-to-stand (Si-St) postural transition we ...

Quantification of tremor and bradykinesia in Parkinson’s disease using a novel ambulatory monitoring system

Kamiar Aminian, Arash Salarian

An ambulatory system for quantification of tremor and bradykinesia in patients with Parkinson's disease (PD) is presented. To record movements of the upper extremities, a sensing units which included miniature gyroscopes, has been fixed to each of the fore ...

Ambulatory monitoring of motor functions in patients with Parkinson's disease using kinematic sensors

Arash Salarian

Parkinson's disease (PD) is the second most common neurodegenerative disease in the general population. Cardinal symptoms of Parkinson's disease are resting tremor, rigidity, akinesia and bradykinesia and in advanced stages, gait impairments, postural inst ...
