Filter by:Nearly 90% of people with Parkinson's disease have speech and voice disorders that negatively impact their ability to communicate effectively in daily life. This study will test the hypothesis that a combined speech and exercise intervention will improve speech intelligibility in people with Parkinson's disease and speech impairment. This approach would offer an affordable way to continue to both instruct and encourage training by Veterans virtually indefinitely through the remote access technology. These findings may help VA clinicians provide optimal care for the many Veterans with Parkinson's disease and speech impairment.
This study aims to better understand how people with Parkinson's control reaching movements. Specifically, we are asking how these individuals respond to different environmental perturbations. Testing includes reaching movements made within a virtual reality set-up.
The aim of this project is to measure behavioural disorders in Parkinson's disease (PD) patients in a more objective way, in order to facilitate the detection of those symptoms and improve the treatment of non-motor symptoms in Parkinson's disease.
Patients with atypical parkinsonism often show gait and mobility impairment manifesting in early disease stages. In order to maintain mobility and physical autonomy as long as possible for these patients, we will examine the effect of two types of physiotherapy in patients with multiple system atrophy (MSA), progressive supranuclear gaze palsy (PSP) and idiopathic Parkinson's disease (IPD). The study is divided into an ambulant daily in-patient physiotherapy phase, followed by a home-based training phase. At the beginning and the end of the study, the patients daily activity will be recorded for one week using Physical Activity Monitoring (PAM) sensors. The aim of this double-blind, randomized-controlled study is to determine effective physiotherapy in patients with atypical parkinsonian syndromes in order to maintain mobility for as long as possible.
Activation is the amount of voluntary recruitment of a muscle during voluntary contraction. Full activation implies the recruitment of all muscle fibres at their tetanic frequency. In healthy subjects, and even in sports performances, full activation may be rarely achieved despite a subjectively maximal effort. Highly decreased activation has been observed in patients affected by various orthopaedic and neurological disorders. In these subjects, paresis may be caused or aggravated by primitive impairments of the central nervous system and/or, by stimuli arising from peripheral damaged tissues that inhibit the corticospinal or the intraspinal recruitment of motoneurones ("arthrogenous muscle weakness"). There are numerous investigations in the literature on activation measured during isometric contractions, while they are substantially missing as far as isokinetic concentric contractions are concerned. There are reasons to suppose that, contrary to what has been demonstrated for healthy subjects, in patients with various motor impairments the activation is diminished the more, the higher is the joint rotation speed. The present study aims to investigate the amount of activation of the quadriceps femoris during subjectively maximal isometric contractions at 40° knee flexion (0°=complete extension) and isokinetic concentric contractions at an angular velocity of 100°/s in patients with various orthopaedic and neurologic conditions. Activation will be measured on an isokinetic dynamometer, through the "interpolated twitch technique". This consists of stimulating a representative sample of the muscle belly through an electric shock. If the shock does not generate an extra force during contraction, all muscle fibres belonging to the sample reached by the electric shock can be claimed to be recruited at their tetanic frequency. Otherwise, following the stimulus, a twitch can be observed revealing submaximal voluntary recruitment of the muscle.
This study is a single-site, double-blinded, randomized clinical trial designed to elucidate mechanism(s) of action for symptomatic benefits observed in Parkinson's disease (PD)
The study will test the feasibility of using Low Intensity Focused Ultrasound Pulsation (LIFUP) to treat motor symptoms in Parkinson's Disease (PD). LIFUP is a new technique that can increase brain activity in highly specific target areas and is MRI compatible. Thus, in real-time, it is possible to directly observe how LIFUP changes the brain areas important in PD by measuring its effects on brain activity, blood flow, and brain connectivity. If successful, this research will mark the first step towards a novel, non-invasive, non-medication treatment for PD.
Investigation on how robotically mediated sensorimotor stimulation induces and triggers presence hallucinations in different clinical groups of parkinsonian patients, and in aged-matched controls
An open label, balanced, randomised, four-treatment, four-period, four-sequence, single oral dose, crossover Pharmacokinetics study of WD-1603 carbidopa/levodopa extended-release tablets in normal, healthy, adult human subjects under fed conditions. A single oral dose of (either Treatment A or B or C or D) carbidopa/levodopa extended release tablets will be administered to each subject within 5 minutes after completion of standardized vegetarian breakfast under fed condition in each period as per randomization schedule.
The study is a randomized, double-blind, sham-controlled cross-over trial to assess the efficacy as well as safety and tolerability of auditory SWS enhancement on measured outcomes in Parkinson disease (PD) patients with disturbed nighttime sleep. Additionally, the investigators will assess the feasibility and efficacy of auditory slow-wave sleep (SWS) enhancement in Mild Cognitive Impairment (MCI) and Huntington Disease (HD) patients in a pilot study.
