Gait assessment in Parkinson's disease: toward an ambulatory system for long-term monitoring
An ambulatory gait analysis method using body-attached gyroscopes to estimate spatio-temporal parameters of gait has been proposed and validated against a reference system for normal and pathologic gait. Expand

iTUG, a Sensitive and Reliable Measure of Mobility
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° turn, andExpand

The instrumented timed up and go test: potential outcome measure for disease modifying therapies in Parkinson's disease
The Timed Up and Go (TUG) test has been used to assess balance and mobility in Parkinson's Disease (PD). However, it is not known if this test is sensitive to subtle abnormalities present in earlyExpand

Body-worn motion sensors detect balance and gait deficits in people with multiple sclerosis who have normal walking speed.
While balance and gait limitations are hallmarks of multiple sclerosis (MS), standard stopwatch-timed measures practical for use in the clinic are insensitive in minimally affected patients. ThisExpand

Ambulatory Monitoring of Physical Activities in Patients With Parkinson's Disease
A new ambulatory method of monitoring physical activities in Parkinson's disease (PD) patients is proposed based on a portable data-logger with three body-fixed inertial sensors. Expand

Comparing the Mini-BESTest with the Berg Balance Scale to Evaluate Balance Disorders in Parkinson's Disease
Objective. The purpose of this study was to explore the usefulness of the Mini-BESTest compared to the Berg Balance Scale in evaluating balance in people with PD of varying severity. We evaluated (1)Expand
