Filter by:Freezing of gait (FoG) is defined as a brief, episodic absence or reduction of forward progression of the feet despite the intention to walk. It is one of the most disabling and intractable motor symptoms in patients with Parkinson's disease (PD) as it often causes falls and loss of independence. The pathophysiology of FoG remains unclear but it seems differ from other cardinal motor symptoms in PD. The therapeutic efficacy of medical and surgical treatments for FoG are usually suboptimal. Deep brain stimulation (DBS) in the subthalamic nucleus (STN) is a well established treatment for advanced PD with motor fluctuation. It alleviates tremor, bradykinesia and rigidity and improved the quality of life. However, the therapeutic effects of DBS are impeded by high cost of device, stimulation induced adverse effects and partial treatment for some parkinsonism symptoms, particular gait disturbance and FoG. Recently, a new mode of stimulation is proposed. Differing from the conventional DBS which is operated in open loop so that stimulation remains fixed over time and is delivered at regular and high frequencies, the new adaptive DBS (aDBS) detects the pathological activities and only deliver stimulation when it is necessary. Recent studies in MPTP-primate and patients with PD demonstrate that the aDBS is superior to standard continuous DBS. However, the therapeutic efficacy is only shown in "appendicular symptoms" such as bradykinesia, rigidity and tremor. There is no report about the effect of aDBS on gait disturbance, particular FoG in PD so far. The aim of the current project is to test whether the therapeutic efficacy of aDBS is superior to conventional DBS in PD patients with FoG. To this end, 20 advanced PD patients who undergo STN DBS implantation for the treatment of their disorders will be examined. The gait of patients will be assessed during conventional open loop stimulation and aDBS and the therapeutic efficacy for FoG will be defined. The results of this study will also contribute to better understanding of pathophysiology of FoG and to future development of embedded aDBS system for PD.
The purpose of this study is to 1. Create a guide for hometitration of Duodopa for patients with Parkinson's disease 2. Outline which patients could be considered for "hometitration"
PARK-FIT Treadmill vs Cycling in Parkinson´s Disease Rehabilitation. Non-pharmacological Clinical Trial for the Definition of the Most Effective Model in Gait Reeducation.
This is a multicenter, open-label, non-controlled, non-randomized, phase 3 clinical study to compare the SPECT findings after a single IV administration of DaTSCAN™ ioflupane (123I) injection for patients with a clinical diagnosis of Parkinsonian syndrome (PS) involving striatal dopaminergic deficit (SDD; specifically, Parkinson's disease [PD] [SDD], multiple system atrophy [MSA] [SDD] or or progressive supranuclear palsy [PSP] [SDD]) as compared with patients with a clinical diagnosis of essential tremor (ET) (no SDD) and age-matched healthy controls.
This is a phase 2 study, randomized, double-blind, placebo-controlled, multicenter study of oral CVN424 at two dose levels (low-dose and high-dose) in Parkinson's disease (PD) patients with motor fluctuations.
Parkinson's disease (PD) is a neurodegenerative disorder associated with a loss of dopamine in the basal ganglia and is characterized by several cardinal motor signs. In addition to the commonly recognized motor symptoms, cognitive impairments are also often observed in people with PD. Unlike motor deficits, cognitive impairments are not always responsive to dopaminergic treatment. While medication may ameliorate some cognitive dysfunctions (e.g., executive function), it may exacerbate others (e.g., motor learning). Therefore, it is crucial for clinicians to look for treatment approaches, other than medication, to enhance cognitive function. In this proposed study, the investigators are especially interested in determining a method to enhance motor learning ability in people with PD. Motor learning deficits in people with PD have been well established through different tasks including motor adaptation task such as maintain balance on a stabilometer or motor sequence task such as performing a serial reaction time task (SRTT). Motor sequence learning is important in acquiring real-life motor skill such as tying shoes laces. Based on the past evidences, people with PD have impairments in motor sequence learning, particularly in implicit sequence learning. Since implicit motor sequence learning constitutes a critical part of everyday activities such as typing and changing clothes, establishing an approach to enhance implicit sequence learning is important. In the literature conducted with non-disable adults, one of the most effective method to enhance motor learning is aerobic exercise. Only one study, to the best of knowledge, has investigated the effect of aerobic exercise on learning to maintain balance on a stabilometer in people with PD. To date, no study has investigated whether a single bout of aerobic exercise could improve implicit sequence learning in PD. Therefore, the goal of this proposed study is to investigate the effect of a single bout of aerobic exercise on implicit sequence learning and the associated neurophysiological changes in people with PD.
The aim of study is to assess validity and reliability of Figure-of-Eight Walk Test in people with Parkinson's Disease
Parkinson disease is a progressive neurologic disorder characterized by motor impairments which alter the walking capacity, and lead to reduced walking speed, decreased stride length and increased double support time. Physical therapy interventions are an important part of the non-pharmacological treatment for Parkinson disease. The purpose of this study was to assess whether there is a different outcome regarding improvement of walking speed, when applying a physical therapy program in an individual or in a group manner. A prospective, observational, cohort type study on 60 patients with Parkinson disease was carried out between November 2014 - July 2017, in the Clinical Rehabilitation Hospital in Cluj-Napoca, Cluj county, Romania. Patients were randomly divided into 2 groups, and were prescribed either individual (1 patient and 1 physical therapist) or group physical therapy (6 patients and 1 physical therapist). Treatment protocol included 10 sessions of physical therapy, in the same room setting and performed the same routine of exercises, except for the 3 breaks during the sessions in the group therapy for informal socialization. Walking speed was measured by two validated instruments, the 6-minute walk test and the 10-meter walk test, before and after treatment. Patients with PD could benefit more from a group physical therapy program, as gait speed increased significantly. The group approach facilitates interactions and is cost-effective, as it requires only one therapist and more patients.
Up till now, dopaminergic replacement is considered as the gold standard for the symptomatic treatment of motor symptoms in Parkinson's disease (PD). However, the intake, especially higher doses when taken for a longer duration, are associated with several side effects including response fluctuations. These fluctuations in medication response are often characterized by a wearing-OFF period, also defined as the recurrence of PD symptoms before a patient should take the next dose of medication. The duration of test sessions during research experiments (e.g. in the field of rehabilitation) can interfere with the period of the optimal therapeutic effect of dopaminergic medication, influencing outcomes of a study. Therefore, the objective of this project is to get more insight in the measurability of ON-OFF fluctuations by testing the applicability of a short and simple timed tapping task (TTT) on a smartphone in rehabilitation research studies. The assessment can be useful for future clinical studies in PD where a precise estimation of medication is indispensable for accurate research outcomes.
