Fitts' law models the relationship between amplitude, precision, and speed of rapid movements. It is widely used to quantify performance in pointing tasks, study human-computer interaction, and generally to understand perceptual-motor information processes, including research to model performance in isometric force production tasks. Applying Fitts' law to an isometric grip force task would allow for quantifying grasp performance in rehabilitative medicine and may aid research on prosthetic control and design...

The numbers of low vision patients will steadily increase because of increasing longevity. It is important to be aware of those patients so that visual rehabilitation can be started as soon as possible and needed. Before the adjustment of low vision devices a diagnosis should be confirmed in order to check any therapeutic option and to ensure the best individual rehabilitation. If there is no further therapeutic option left a detailed anamnesis of the problems due to low vision should be made to ensure that every patient gets the optical or electronic device he really needs in his everyday life...

m-Health is an emerging area that is transforming how people take part in the control of their wellness condition. This vision is changing traditional health processes by discharging hospitals from the care of people. Important advantages of continuous monitoring can be reached but, in order to transform this vision into a reality, some factors need to be addressed. m-Health applications should be shared by patients and hospital staff to perform proper supervised health monitoring. Furthermore, the uses of smartphones for health purposes should be transformed to achieve the objectives of this vision...

PURPOSE: Older adults with low vision are a growing population with rehabilitation needs including support with community mobility to enable community participation. Some older adults with low vision choose to use mobility scooters to mobilize within their community, but there is limited research about the use by people with low vision. This paper describes a pilot study and asks the question: what are the experiences of persons with low vision who use mobility scooters? METHODS: This study gathered the experiences of four participants with low vision, aged 51 and over, who regularly use mobility scooters...

Apraxia of speech is a motor speech disorder in which messages from the brain to the mouth are disrupted, resulting in an inability for moving lips or tongue to the right place to pronounce sounds correctly. Current therapies for this condition involve a therapist that in one-on-one sessions conducts the exercises. Our aim is to work in the line of robotic therapies in which a robot is able to perform partially or autonomously a therapy session, endowing a social robot with the ability of assisting therapists in apraxia of speech rehabilitation exercises...

We hypothesised that rehabilitation specifically addressing balance in Parkinson's disease patients might improve not only balance but locomotion as well. Two balance-training protocols (standing on a moving platform and traditional balance exercises) were assessed by assigning patients to two groups (Platform, n = 15, and Exercises, n = 17). The platform moved periodically in the anteroposterior, laterolateral, and oblique direction, with and without vision in different trials. Balance exercises were based on the Otago Exercise Program...

Age-related macular degeneration (AMD) is the leading cause of visual impairment in the western world, causing significant reduction in quality of life. Despite treatment advances, the burden of visual impairment caused by AMD continues to rise. In addition to traditional low vision rehabilitation and support, optical and electronic aids, and strategies to enhance the use of peripheral vision, implantable telescopic devices have been indicated as a surgical means of enhancing vision. Here we examine the literature on commercially available telescopic devices discussing their design, mode of action, surgical procedure and published outcomes on visual acuity, quality of life, surgical complication rates and cost effectiveness data where available...

AIM: To estimate the prevalence of glaucoma in Australia. METHODS: This was a population-based study of 3098 non-Indigenous Australians (50-98 years) and 1738 Indigenous Australians (40-92 years) stratified by remoteness. Each participant underwent a standard examination that included visual field assessment, tonometry and non-mydriatic fundus photography. Two fellowship-trained glaucoma specialists independently assessed relevant case notes (past ocular history, best-corrected visual acuity, frequency doubling technology visual fields, Van Herick grade, intraocular pressure and optic disc-centred photographs) and assigned a diagnosis ranked on a scale of certainty: none, possible, probable or definite glaucoma...

BACKGROUND: The Sustainable Development Goals (SDGs) are seen in most corners as the embodiment of a more inclusive and holistic development approach, key to addressing the numerous and urgent challenges the world faces. In the health realm, a true SDG approach will require a five-fold paradigm shift according to Buse and Hawkes. This article explores whether early traces of this paradigm shift can already be witnessed in the Indian context, focusing on Non-Communicable Diseases (NCDs) more in particular...

SIGNIFICANCE: Our survey found that participants with hemianopia report more difficulties watching video in various formats, including television (TV), on computers, and in a movie theater, compared with participants with normal vision (NV). These reported difficulties were not as marked as those reported by people with central vision loss. PURPOSE: The aim of this study was to survey the viewing experience (e.g., frequency, difficulty) of viewing video on TV, computers and portable visual display devices, and at the cinema of people with hemianopia and NV...

Diabetic retinopathy (DR) is one of the leading causes of vision loss globally with a severe burden on all societies due to its high treatment and rehabilitation costs. The early diagnosis of DR may provide preventive steps (including retinal laser therapy and tight carbohydrate, blood pressure, and cholesterol control) that could in turn help to avoid progression of the pathology with the resultant vision loss. Optical coherence tomography (OCT) enables the in vivo structural imaging of the retina, providing both qualitative (structure) and quantitative (thickness) information...

BACKGROUND: The purpose of low-vision rehabilitation is to allow people to resume or to continue to perform daily living tasks, with reading being one of the most important. This is achieved by providing appropriate optical devices and special training in the use of residual-vision and low-vision aids, which range from simple optical magnifiers to high-magnification video magnifiers. OBJECTIVES: To assess the effects of different visual reading aids for adults with low vision...

BACKGROUND: Driving cessation is strongly associated with adverse health outcomes in the older adults. Although there were numerous documentations of driving rehabilitation in disabled adults, the effects of interventions on safe driving were not clear in older adults with cognitive impairment who had low driving skills. OBJECTIVE: This randomized controlled trial was designed to determine whether a safe driving skill program consisting of classroom and on-road training could enhance driving performance of older drivers with cognitive impairment in Japan...

BACKGROUND: Individuals with visual impairment (VI) have often been observed to walk slower than individuals with unimpaired vision. These observations might be confounded by typical low levels of physical activity and greater sedentary behavior in individuals with VI than the overall population. RESEARCH QUESTION: Here, we compared gait and balance measures between individuals with VI who participate in disability sports, and activity level matched sighted individuals...

Retinitis pigmentosa (RP) encompasses a group of inherited retinal dystrophies characterized by the primary degeneration of rod and cone photoreceptors. RP is a leading cause of visual disability, with a worldwide prevalence of 1:4000. Although the majority of RP cases are non-syndromic, 20-30% of patients with RP also have an associated non-ocular condition. RP typically manifests with night blindness in adolescence, followed by concentric visual field loss, reflecting the principal dysfunction of rod photoreceptors; central vision loss occurs later in life due to cone dysfunction...

Injuries are an inevitable part of competitive sports as well a recreational activities. Research shows that one of the most common musculoskeletal complaints that accounts for approximately 48 out of 1,000 patients are knee related injuries.1 As noted, approximately nine percent of these knee complaints are related to anterior cruciate ligament (ACL) injuries.2 ,3 The ACL is commonly injured in contact sports via a non-contact action such as planting, cutting, landing on a hyperextended knee, or pivoting and sudden deceleration...

Perceptual learning (PL) has been traditionally thought of as highly specific to stimulus properties, task and retinotopic position. This view is being progressively challenged, with accumulating evidence that learning can generalize (transfer) across various parameters under certain conditions. For example, retinotopic specificity can be diminished when the proportion of easy to hard trials is high, such as when multiple short staircases, instead of a single long one, are used during training. To date, there is a paucity of mechanistic explanations of what conditions affect transfer of learning...

OBJECTIVES: To evaluate the ability of saccadic strategies developed during vestibular compensation to reduce the effect of an impaired vestibulo-ocular reflex (VOR) on a retinal smear and image motion sensation. DESIGN: Twenty patients with unilateral vestibular loss were examined with a video head impulse test before and after vestibular rehabilitation (VR) with the use of gaze stabilization and refixation saccades training. Head and eye velocity functions were processed to infer the retinal eccentricity, and through its correlation with visual acuity (VA), several measurements are proposed to evaluate the influence of VR on saccades behavior and visual performance...
