The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments. The main questions it aims to answer are: 1. Can the 6-week IVR stimulation program help improve driving performance? 2. Will participants experience improvement in visual detection and perception after training? Study Design Summary: - Participants will be randomized into a waitlist group or intervention-first group - The VR-based intervention will consist of training every 2 days for six weeks - Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7) - Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint - Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study Researchers will analyze data for changes from baseline in outcome measures.
Seniors deal with considerable visual demands (driving, communicating, traveling) and reduced vision affects their quality of life, ability to enjoy activities, and age-in-place. Vision loss has a heavy, increasing, economical and social burden. It can also have substantial impacts on caregivers physically, psychologically, and financially because one tends to miss more work, be less productive, and thus have fewer job opportunities. This registration will describe the clinical portion of a larger study designed to evaluate both the feasibility and effectiveness of the Re:Garde Program, a Virtual Reality (VR) visual training program for older adults to help maintain visual perception to promote quality of life and prolonged independence. In partnership with our care partners the investigators will implement the Re:Garde Program at an interprofessional clinic and as part of a loaning program for older adults to use in the home. The clinical portion of this study will look at how effective the Re:Garde program is at maintaining or improving visual perception, ability to conduct activities of daily living (e.g. read, drive, cook, exercise etc.), general wellness, and quality of life. The feasibility of implementing this program in the two settings will be evaluated separately as part of the full protocol.
OdySight is a mobile application allowing self-testing of visual parameters including near visual acuity and communication of the data to an online dashboard to patient's doctors. TIL-002 post-market clinical trial objective is to evaluate the near visual acuity at home, measured with OdySight application in comparison to the standardized methods. The clinical trial is intended to prove that OdySight can provide relevant data and participate in the remote monitoring of subject vision.
Chronic NonSpecific Low Back Pain (CNSLBP) is a common musculoskeletal condition often resulting in physical inactivity and disability. CNSLBP is associated with a large number of social and health costs, being one of the most important health problems worldwide. Although Therapeutical Exercise (TE) has been shown to be effective in increasing physical activity tolerance, physical fitness, strength, self perceived quality of live, pain tolerance, and overall physical activity participation levels in persons with CNSLBP, pain-release-passive therapy modalities are significantly more commonly used in clinical settings at present. On the other hand, the use of tele-assistance platforms PTAs has been gaining importance in the treatment of CNSLBP patients, especially in the use of semi-directed TE programs. However, current PTAs are not accessible for the visually impaired, a group that is at greater risk of suffering from sedentary lifestyles, restricted mobility and musculoskeletal pain due to postural or gait changes. The main hypothesis of these study is that a semi-directed TE and health education programm, in people with and without visual impairment, achieves better results in movement capacity, functional recovery, strength and compared to passive analgesic treatment in patients with CNSLBP. In a second objective, we will assess the efficacy and usability of a new PTA accesible tool for the follow-up of patients with CNSLBP who are visually impaired.
To assess repeatability of electroretinogram and visual evoked potential in clinical practice
The goal of this project is to quantify and computationally model the perceptual experiences of Argus II retinal prosthesis patients. The investigators will produce visual percepts in patients either by directly stimulating electrodes or by asking them to view a computer or projector screen and using standard FDA-approved stimulation protocols (as is standardly used for their devices) to convert the computer or projector screen image into pulse trains on their electrodes. Performance of patients will be compared to that of sighted control subjects viewing a simulation of the vision generated by Argus II in virtual reality.
In their day to day, persons do from simple to more or less complicated tasks and activities (ie: stand from a chair, open a door, shopping, read, drive, play chess, remind an appointment...). Such ability to do things is called capacity. Intrinsic capacity is the combination of all the physical and mental capacities that a person has, and reach its maximum in the early adulthood and then declines as the person ages. Each kind of capacity declines at her own speed (which may be faster or slower according to each person lifestyle), and once drops below a threshold may lead to a reduction in quality of life and loss of autonomy. Nevertheless there are some actions that may be effective to prevent or slow such decline. To do so the investigators have design an intervention that combines several things of different nature (what is know as a complex intervention) called AMICOPE. The AMICOPE intervention is performed in the community or in primary care centers through 12 weekly group sessions of 2 h 30 min which combine structured and adapted physical activity, group dynamics to promote social support and address loneliness, social isolation and depressive symptoms, and dietary advice. Our study is addressed to persons over 70 with light problems in mobility, nutrition or mood state. The purpose of this study is to assess if the AMICOPE intervention is better than the standard advice to follow healthy lifestyles to improve or maintain self-perceived health, mobility, nutritional status an psychological wellbeing.
A visual impairment (VI) is often associated with reduced psychological wellbeing. Music can be used in a variety of ways to promote psychological wellbeing. Music intervention studies demonstrate that listening to music can provide a distraction from unpleasant thoughts/feelings. Hence, music may serve as a catalyst to improve mood and relieve feelings of depression, anxiety, and stress. The purpose of this study is to investigate if it is feasible for people with acquired VI to self-deliver daily music listening (music alone or with mindful music listening instructions) for wellbeing, in participants homes, for four-weeks, and to collect data remotely on efficacy in reducing symptoms of anxiety and depression and treatment fidelity.
This project assesses the effect of bifocal cross-frequency transcranial alternating current stimulation (tACS) combined with visual training to improve visual recovery and orchestrated oscillatory activity in stroke patients suffering from visual field defects.
