INTRODUCTION: Motor performance in Park-inson’s Disease (PD) patients is generally analyzed in laboratory. However, laboratory techniques do not allow estimating long-term ON/OFF fluctua-tion in PD patients. Here, we propose an ambula-tory system based on ...
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. Later, ten Parkinson's disease (PD) patients with su ...
Summary: Using our ambulatory monitoring system, ASUR, 13 Parkinsonian patients were monitored for periods of up to 5 hours while they were free to perform activities at will. Every one hour patients did a UPDRS test as the clinical assessment. During the ...
In this study we describe an ambulatory system for estimation of spatio-temporal parameters during long periods of walking. This original method based on wavelet analysis is proposed to compute the values of temporal gait parameters from the angular veloci ...
Sensory feedback from the moving limbs contributes to the regulation of animal and human locomotion. However, the question of the specific role of the various modalities is still open. Further, functional loss of leg afferent fibres due to peripheral neuro ...
We recorded basic gait features and associated patterns of leg muscle activity, occurring during continuous body progression when humans walked along a curved trajectory, in order to gain insight into the nervous mechanisms underlying the control of the as ...
A piezoelectric elastic fin micromotor based on a PbZr0.53Ti0.47O3 thin film driving a micromachined silicon membrane was fabricated and studied. The stator was characterized by interferometry, and a laser set-up was used to measure the angular velocity an ...
Recovery of locomotor function was investigated in seven cosmonauts exposed to microgravity for 6 months. Crew members executed a locomotor task with visual cues (eyes open, EO) and without them (eyes closed, EC). The locomotor task consisted of ascending ...
