Strategy Training for Individuals With Unilateral Neglect

Start date: July 1, 2024
Phase: N/A
Study type: Interventional

It is common for individuals after stroke to have a cognitive perceptual impairment called unilateral spatial neglect (neglect). Individuals with neglect have difficulty paying attention to one side of their body or one side of the environment and therefore experience difficulty performing daily activities. There are a lack of effective treatments for neglect and new interventions are needed to help reduce disability for these individuals. Metacognitive strategy training (strategy training) is an intervention that has the potential to reduce neglect-related disability and improve individuals' awareness of their neglect. This study seeks to examine the effects of strategy training on self-awareness, disability, and neglect.

Immersive Virtual Reality Treatment for Unilateral Spatial Neglect

Start date: March 11, 2024
Phase: N/A
Study type: Interventional

Unilateral Spatial Neglect (USN) is a relatively common neuropsychological syndrome following stroke. It is characterized by difficulties in detecting, orienting and identifying events located in the hemispace contralateral to a brain lesion, unrelated to a primary motor or sensory disorder. Numerous methods have been developed for the rehabilitation of this syndrome. However, limitations in terms of efficacy are highlighted. These limitations may be linked to the fact that these methods are restricted to certain sensory modalities, thus failing to take into account the heterogeneity of the syndrome. Moreover, some patients' adherence to rehabilitation programs can also be complicated by motivational difficulties. Immersive Virtual Reality could help overcome these limitations. Indeed, it enables the introduction of new sensory modalities, notably auditory, to support a better apprehension of space. The main objective of this study is to determine the efficacy of an immersive virtual reality rehabilitation protocol based on musical practice in patients suffering from USN. This study also aims to explore the benefits of this rehabilitation protocol on patients' daily lives, as well as to explore the influence of patients' mood and motivation on the benefits of the immersive virtual reality rehabilitation protocol. To achieve these goals, patients will benefit from immersive virtual reality rehabilitation based on music practice. This rehabilitation will be compared to conventional USN rehabilitation. To this end, patients will be divided into two groups: classical rehabilitation only or classical rehabilitation and immersive virtual reality in parallel. Each patient will be randomly assigned to one of the two groups for a period of 2 weeks. Pre- and post-rehabilitation assessments will be provided.

Immersive Virtual REality for Treatment of Unilateral Spatial NEglect Via Eye-tracking Biofeedback

IRENE
Start date: November 1, 2023
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the effects of a treatment using virtual reality on the recovery of unilateral spatial neglect. The investigators hypothesize that the experimental group underwent to a protocol of active exercises within the virtual environment will show an improvement in the exploratory functions of the left hemispace, investigated with specific scales and clinical tests.

Evaluation of the Efficacy of Low-Frequency Repetitive Transcranial Magnetic Stimulation on Unilateral Neglect in Patients With Subacute-Chronic Phase After Ischemic Stroke

Start date: June 15, 2023
Phase: N/A
Study type: Interventional

The aim of this study was to randomize stroke patients with unilateral neglect into 2 groups, active and sham groups, and to examine the effects of active inhibitory repetitive transcranial magnetic stimulation on the reduction of neglect symptoms, functional recovery and independence of these patients in activities of daily living.

NCT ID: NCT06050408 Not yet recruiting - Clinical trials for Neglect, Hemispatial

Assessment of LF-rTMS in Patients With Visual Neglect

Start date: September 15, 2023
Phase: N/A
Study type: Interventional

Visual neglect is a common disorder following stroke and an indicator of poor recovery compared to stroke survivors without visual neglect. The goal of this intervention study is to assess the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in reducing visual neglect symptoms in patients following a stroke. The aim is to answer these questions: 1. Does rTMS decrease visual neglect symptoms in patients following a stroke? 2. If the treatment works, when in the rehabilitation process is it most effective to provide the treatment (6-12 weeks, 16-42 weeks or 52+ weeks after the stroke).

Public Health Impact of Unilateral Spatial Neglect

IMPAssNEGLECT
Start date: February 7, 2022
Phase:
Study type: Observational

This multi-center project aims to quantify the socio-medical costs associated with Unilateral Spatial Neglect (USN) resulting from acquired brain injury (stroke) and to measure the effects of USN rehabilitation on functional autonomy, quality of life and psychological well-being of patients affected by this syndrome, considering the repercussions on a psychological level and on the quality of life of caregivers. To this end, the experimenters will administer to right brain-injured patients - with (Experimental Group) or without (Control Group) USN - who undertook a rehabilitation process, a series of questionnaires: Activities of daily living (ADL), Barthel Index; Instrumental activities of daily living scale (I-ADL:), the Health Related Quality of Life questionnaire (EQ-5D-5L), the Geriatric Depression Scale (GDS), and the State-Trait Anxiety Inventory (STAI-Y). The aforementioned tests will be administered before the start of the rehabilitation (baseline) and after one month, 3, 6 and 12 months after the end of the rehabilitation. The impact of USN and its treatment on the psycho-physical well-being of the caregiver will be measured through the Caregiver Burden Inventory questionnaire, which will be administered with the same timing (baseline, 1-3-6-12 months after rehabilitation). The costs of USN will be surveyed through an ad-hoc questionnaire, which includes a version intended for patients and one for caregivers, in order to identify the resources consumed due to the disease and the expenses taken during the observation period, to be estimated subsequently in monetary terms (€).

Spatial Cognition Assessment in Virtual Reality

CogSpa-VR
Start date: January 1, 2022
Phase: N/A
Study type: Interventional

Unilateral spatial neglect (USN) is a highly-prevalent neuropsychological syndrome following a cerebral stroke characterized by massive impairments in daily life. The evaluation and the rehabilitation of USN encounter many limits whereas immersive virtual reality (VR) could be an efficient tool to go through these limits by imitating an environment of perception and action very close to the real one. The investigators will test a multisensory battery of evaluation based on VR for the diagnostic of USN.

Lesion Site and Neglect Anosognosia in Patients With Left Hemispatial Neglect

Start date: December 16, 2022
Phase:
Study type: Observational

The goal of this retrospective is to investigate the relationship between lesion site and neglect anosognosia in subacute or chronic right hemispheric stroke patients with left hemispatial neglect. The main questions it aims to answer are: - Was any lesion site related to a higher neglect anosognosia rate? - Did any lesion site related to a more severe neglect anosognosia? Participants will be divided into two groups regarding the presence of anosognosia for spatial neglect. Researchers will compare patients with and without anosognosia to see if any lesion site resulted in a higher anosognosia rate and more severe unawareness of neglect symptoms in daily life.

Engaging Mobile Prism Adaptation Treatment at Home

EMPATH
Start date: November 2022
Phase: Phase 1
Study type: Interventional

Spatial neglect is a common disorder after stroke which leads to problems with noticing or responding to information from the left side of the body or space. This condition has been linked to reduced independence in a wide range of daily life activities including eating, dressing, and mobility. Despite its high prevalence in stroke patients, there is currently no standard of care for spatial neglect. Prism adaptation (PA) is a promising treatment, however, there are limitations to using PA in standard clinical care as it requires daily exposure for at least two weeks, yet access to equipment and supervision is limited. To solve this problem, the investigators have developed a new game-like PA treatment (Peg-the-Mole, PTM) that can be used at home without the need for daily in person therapist set-up and supervision. In this study the investigators aim to evaluate the feasibility and effectiveness of the gamified and portable PA procedure in an inpatient and home setting, with the hypothesis that the PA procedure will improve patient's neglect symptoms.
