Parkinson's disease (PD) is a chronic progressive neurodegenerative disease that is
clinically manifested by a triad of cardinal motor symptoms—rigidity, bradykinesia and …

(1) Background: One of the main cardinal signs of Parkinson's disease (PD) is rigidity,
whose assessment is important for monitoring the patient's recovery. The wrist is one of the …

A cardinal feature of Parkinson's disease (PD) is muscle hypertonicity, ie rigidity. Little is
known about the axial tone in PD or the relation of hypertonia to functional impairment. We …

This work focuses on the design and the validation of a wearable mechatronic device for an
at-home assessment of wrist stiffness in patients affected by Parkinson's Disease (PD). The …

OBJECTIVE: Muscle spasticity following stroke has been shown to result from limitations in
the range of regulation of the tonic reflex spatial threshold (ST), ie, the joint angle at which …

We propose a novel system that analyzes the components of rigidity in Parkinson's disease
(PD) usually perceived by physicians, in a very simple and systematic way for routine clinical …

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been shown to be an
effective treatment for Parkinson's disease (PD). The intraoperative positioning of DBS …

We quantified the effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN)
and medication on Parkinsonian rigidity using an objective measure of work about the elbow …

Objective Increased muscle activity during rapid eye movement (REM) sleep (ie REM sleep
without atonia) is common in people with Parkinson's disease (PD). This study tested the …

This study aims to analyze viscoelastic properties of the wrist in patients with Parkinson's
disease (PD) in comparison with the clinical score of severity. Forty-five patients with PD and …
