Split-belt Treadmill Training to Rehabilitate Freezing of Gait and Balance in Parkinson's Disease

Start date: March 27, 2020
Phase: N/A
Study type: Interventional

Parkinson's disease (PD) related gait and balance disorders are challenging to treat because they cannot be optimized with pharmacological intervention alone. This treatment gap is important to address because gait asymmetry and incoordination are associated with increased falls in this population, which can be functionally debilitating and lead to increased morbidity and mortality. Freezing of gait (FOG) has also been associated with reduced quality of life independent of its association with impaired mobility. Gait disorders therefore represent an unmet need in the treatment of PD. A split-belt treadmill (SB-TM) can be used to adjust the speed of each leg separately and individuals can be prompted to 'adapt' to an asymmetric gait and 're-adapt' with return to symmetrical gait in a phenomenon known as 'after-effect'.

Neurorehabilitation of Sequence Effect in Parkinson's Disease

Start date: August 1, 2019
Phase:
Study type: Observational

The sequence effect (SE), defined as a reduction in amplitude of repetitive movements, is a common clinical feature of Parkinson's disease (PD), being a major contributor to freezing of gait (FOG). During walking, SE manifests as a step-by-step reduction in step length when approaching a turn or gait destination (dSE). The investigators studied the effect of a 4-week rehabilitation program on the destination sequence effect in patients affected by Parkinson's disease with and without Freezing of Gait. All subjects were evaluated with inertial gait analysis for dSE recording.

Provocation of Freezing of Gait in Parkinson's Disease

Start date: March 15, 2021
Phase: N/A
Study type: Interventional

Sample Size N= 10 Parkinson's disease patients with self-reported freezing of gait and 10 without self-reported freezing of gait (in total, 20 Parkinson's disease patients) Accrual Period Single visit for 2 hours Study Design This is a cross-sectional study with an intervention to provoke freezing of gait using split-belt treadmill in Parkinson's disease patients with a randomized cross-over design. After baseline evaluation (a), interventions to induce freezing of gait will be performed in a randomized order to avoid a practice/fatigue effect in the following conditions using combination of 4 interventions: walking speed (fast walking vs. natural walking), visual loading (passing through narrow pathway), cognitive loading (dual task), and asymmetry (best side reduction). 1. Natural and fast walking with self-paced mode to access gait parameters and decide the speed for evaluation (3 mins X2) remaining assessment will be randomized and performed on the treadmill: 2. Natural and fast walking passing through narrow pathway (2 mins X2) 3. Natural and fast walking with dual task (2 mins X2) 4. Natural and fast walking passing through narrow pathway and during cognitive dual task (2 mins X2) 5. Natural and fast walking reducing the best side (2 mins X2) 6. Natural and fast walking reducing the best side passing through narrow pathway (2 mins X2) 7. Natural and fast walking reducing the best side with cognitive dual task (2 mins X2) 8. Natural and fast walking reducing the best side passing through narrow pathway and during cognitive dual task (2 mins X2) - Conditions b-h will be carried out on a split-belt treadmill (Grail systems®, by Motek, Netherlands). - (b-i) freezing of gait episodes will be identified with synchronized videorecordings (screening done by two independent observers). Episodes identified by both observers will be confirmed and measured by comparing the relative height of metatarsal and heel markers of each foot, in keeping with a previous study evaluating freezing of gait episode on a treadmill. Study Duration 1. (Baselines evaluation) Enrolment and assessment (Montreal cognitive assessment, Movement Disorders Society-unified Parkinson's disease rating scale part 2, 3 and 4, Activities-Specific Balance Confidence Scale, Parkinson's disease questionnaire-39, and New freezing of gait questionnaire) 2. (a) Formal gait analysis using split-belt treadmill (Grail systems®, by Motek, Netherlands) will be done for baseline assessment (normal walking) and to test patient's ability for fast walking (25% of the normal speed). 3. (b-h) Provocation of freezing of gait at split-belt treadmill (Grail systems®, by Motek, Netherlands) with natural and fast walking with/without additional loading or interventions on the asymmetry Total time= 2 hours Study Intervention Freezing of gait will be provoked based on the situations combined among 4 conditions; (1) interventions on asymmetry, (2) cognitive dual task, (3) visual loading - passing through narrow pathway, and (4) walking speed at a split-belt treadmill. - Fast walking will be defined as walking 25% faster than the normal comfortable walking. Subjects who cannot reach this speed, will be asked to walk at their safest maximum speed. - Passing narrow pathway will be done by walking in a "rope bridge" scene in virtual reality (VR). - Dual cognitive task will be carried out with serial subtraction prompted on the screen in VR. - Best side reduction will be defined as 25% slower speed on the best side based on the speed during the initial natural walking with tied configuration setting based on a previous study.3 - Condition b-h will be randomized.

Usability of a Novel Cueing Device for Patients With Parkinson's Disease

TCP
Start date: November 16, 2020
Phase: N/A
Study type: Interventional

Hypokinetic gait disorder and Freezing of Gait (FOG) are frequent symptoms in the advanced stage of Parkinson's disease (PD). These impair quality of life and significantly increase the risk of falls. External movement pacemakers have been developed to improve gait and avert FOG by cueing strategies. The investigators developed a smart, small and lightweight, easy-to-handle wearable tactile cueing device (TCD), consisting of a control unit, two pulse generators and a battery-driven power supply. The device is programmed via a Graphical User Interface (GUI).

Selectively Modulating Pathophysiological Biomaker to Improve Freezing of Gait in Parkinson' s Disease by Adaptive Subthalamic Stimulation

Start date: August 20, 2019
Phase: N/A
Study type: Interventional

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 Effect of Split-belt Treadmill Training on Gait in Parkinson's Disease

Start date: August 12, 2019
Phase: N/A
Study type: Interventional

People with Parkinson's disease (PD) often show gait impairments such as, shuffling gait, short steps and gait asymmetry and irregularity. These gait problems are already apparent in the early disease stages, having an immense effect on daily life functioning. Especially Freezing of Gait (FOG), where the patients are not able to initiate or continue their movement despite their intention to do so, is a debilitating problem. It is thought that lack of gait adaptability could be an underlying cause of FOG. With a split-belt treadmill the speed of both legs can be controlled independently, which forces participants to actively adapt their gait to the new situation. In a previous study performed at our lab, it was shown that only one session of split-belt training (SBT), in which the speed of one leg was reduced, improved gait adaptability and other gait features compared to tied-belt training (TBT). Furthermore, overground turning speed improved after only one single training session and this was even retained 24 hours later, indicating training induced long-term potentiation. Since the short-term effects of SBT are promising, the objective of this study is to investigate if 4 weeks of SBT, 3 times a week, has an effect on gait deficits found in individuals with PD, compared to 4-weeks, 3 times a week, of TBT.

Motor Adaptation to Split-Belt Treadmill in Parkinson's Disease

Start date: December 1, 2017
Phase: N/A
Study type: Interventional

Freezing of Gait (FOG) is a disabling symptom common in advanced Parkinson's Disease. FOG is an independent contributor to fall risk and is only partially relieved by medication. Parkinson's patients with FOG are known to have more difficulty with gait adaptation in their day to day environment. Further, asymmetry of gait has been implicated in FOG as these episodes are often elicited during asymmetric tasks such as turning. This study will examine the effect of a single session of split-belt treadmill walking on gait adaptation, gait symmetry and FOG as well as 24 hour retention of these effects.
