Abstract

Introduction:

Blind people lose an important degree of independence, which makes it difficult to carry out different activities of daily life.

Objective:

To develop and evaluate a telecare model that consisted of guiding a person with visual disability through a video conference to carry out activities of daily life.

Methods:

The telecare model is based on the guidance through voice commands. Telecare begins when a blind person, through a mobile device, transmits images, video and voice (video conference) in real-time to a person with normal vision in a different place that works as a guide, so that the guide knows the details of the blind person. The environment of the person that can solve immediate information needs, location or selection of objects requires visual support. It was evaluated with 37 people with visual disabilities through the Lawton & Brody scale.

Results:

It is an improved progressive evolution in the level of independence of the Lawton and Brody scale, which presents an advance of just over 2 points in the scale thanks to the tele-assistance application (p = 0.000).

Conclusion:

The participants were at a moderate level of dependence and, after the tele-assistance tests, their level was mild. The highest score was obtained in activities related to money management and purchases. In contrast, participants had less value activities within the home. The results allowed us to verify the effectiveness of telecare to improve the independence and well-being of people with visual disabilities.

Keywords: Health, Blindness, Visually impaired persons, Video conference, Orthosis, Mobile health (MeSH terms).

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
