Filter by:Purpose of this study was to assess the relationship between the visual impairment degree and the level of children's fundamental motor skills, balance and bilateral coordination.
A broad definition of visual impairment includes a wide continuum of visual function loss. Aspects of visual function include visual acuity, which is the capacity to resolve detail, and accommodation (capacity to concentrate), field of vision (the area that may be seen), colour perception, and light sensitivity. A child with cerebral blindness can nevertheless be able to perceive motion. There are numerous sources of prevalence information, each of which has drawbacks. One of the fundamental pillars of the major worldwide prevention of blindness project, VISION 2020 the Right to Sight, is the reduction of visual impairment and blindness in children in resource-poor nations. Refraction and poor vision services aid visually impaired children, especially those with genetic or congenital ocular defects and enable vision improvement.
Patients with parkinson disease (PD) usually reduced the dose the levodopa after received deep brain stimulation (DBS). However, studies seldomly mentioned about the influences on non-motors systems after the reduction. Our study focused on the changes after DBS and attribute them to the levodopa variety.
Visual impairment is used to describe any kind of vision loss, whether it's someone who cannot see at all or someone who has partial vision loss. Visual impairment is classified on the basis of visual acuity like mild, moderate, severe, profound, near total visual impairment, no light perception (NLP). Balance is defined as the ability to maintain one's equilibrium as the center of gravity when the COG shifts called (dynamic balance), as in walking and running, and while the center of gravity remains stationary (static balance). Mobility is the ability of a patient to change and control their body position. Physical mobility requires sufficient muscle strength and energy, along with adequate skeletal stability, joint function, and neuromuscular synchronization. This will be a randomized controlled trial. Approval will be gained from the Ethical committee of the Riphah international university Lahore, Pakistan prior to the commencement of study. Written informed consent will be taken from all the patients and all information and data will be confidential. Subjects will be informed that there is no risk of study and they will be free to withdraw any time during process of study. 24 patients will be divided into two Groups. Group A will be the Control Group that will be given the baseline treatment of static balance training (static exercises like standing on balance board, bounce on one foot, heel rises/toe rises, standing on one foot, jumping on trampoline) and Group B will be the Experimental Group that will be provided with baseline treatment along with dynamic balance training (cross, side and tandem walking, step up and down, jumping and hopping on floor). Exercises will be given the 40 minutes with 2 sessions per week over the period of 8 weeks. Pre and Post treatment values will be evaluated. The tools used will be Time Up and Go Test, GMFM-88, Wee FIM. Data will be analyzed using SPSS 22.0 and mean and standard deviation will be calculated.
the purpose of the study is to evaluate the software usability and patient's adherence from five vision rehabilitation centres. In addition, the effect and benefits of a customizable telerehabilitation program were tested.
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.
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.
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.
In this study, the study team utilize virtual reality (VR) to simulate visual impairments of different types and severity in healthy subjects. The platform implements three of the most widespread forms of visual impairment in the United States (US): age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma, each with three levels of severity, (mild, moderate, and severe). At present, glaucoma is further developed toward a multidimensional visual impairment simulation. The platform is utilized: i) to provide a safe, controllable, and repeatable set of environments for development and preliminary testing of electronic travel aids (ETAs) in a variety of conditions (i.e., using the ETA to navigate in the immersed environment); and ii) to equip blind and low vision (BVI) professionals, inclusive of orientation and mobility (O&M) instructors, with a controlled, tunable training platform for skill/capacity building, assessment, and refinement of O&M techniques, as well as visually impaired trainees with a safe and immersive environment to improve their O&M skills and learn novel techniques. Two sets of hypothesis-driven experiments are proposed to assess the feasibility of the platform with respect to these two objectives.
Cerebral Palsy (CP) is the most common childhood disorder that occurs with a lesion in the developing infant brain, seen in 2-3/1000 live births. CP is a posture, movement and tone disorder that occurs due to prenatal or postnatal causes. It is not progressive, but since the anatomy of the lesion and the physical development of the individual are not completed, the course of the disorder may vary throughout life. Accompanied by motor dysfunctions, it varies according to clinical types. In addition to this, various visual, sensory and behavioral problems, speech disorders that cause learning difficulties and cognitive problems can also be observed. Ophthalmic disorders are the most common problem in CP and can also affect the developmental process of the patient. Since ophthalmic disorders and neurological deficits are associated in CP, the relationship between neurological disorder and ophthalmic disorders has been investigated in the literature. The aim of this study is to establish the Turkish validity and reliability of the Visual Function Classification System (VFCS) specific to individuals with Cerebral Palsy (CP).
