Quality of Life Assessment of Severely Visually Impaired Individuals Using Aira Assistive Technology System.

ABSTRACT: Purpose:To assess patient-reported quality of life outcome improvements in severely visually impaired (SVI) individuals using the Aira system over a 1-year follow-up period. Methods:Aira is an on-demand assistive technology designed for SVI. Aira subscribers were recruited and administered the validated 28-item Impact of Vision Impairment-Very Low Vision Questionnaire by phone before starting Aira with follow-ups at 3 months and 1 year. Total score and validated subset scores of activities of daily living, mobility, and safety (ADLMS) and emotional well-being (EWB) were assessed. Pearson correlation analyses and paired t-tests were used to examine the data. Results:Fifty participants (mean, age, 52.5 years; 25 males, 25 females) were recruited with a mean of 401 ± 66.3 days to follow-up. The initial total score (mean, 53.1 ± 18.9) significantly improved at 1 year (mean, 63.1 ± 16.2; P = 0.0002). The initial ADLMS score (mean, 30.7 ± 11.3) significantly improved at 1 year (mean, 37.2 ± 10.7; P = 0.001). The initial EWB score (mean, 22.5 ± 8.5) significantly improved at 1 year (mean, 25.9 ± 8.0; P = 0.0001). There was no significant difference between the 3-month and 1-year total (P = 0.972), ADLMS (P = 0.897), and EWB scores (P = 0.700). There was a significant correlation between minutes used and improvement in total (r = 0.371; P = 0.009), ADLMS (r = 0.302; P = 0.035), and EWB (r = 0.439; P = 0.002) scores. Conclusions:Aira use significantly improves Impact of Vision Impairment-Very Low Vision total, ADLMS, and EWB scores for SVI individuals at 3 months. This improvement is sustained at the 1-year follow-up and correlated with total minutes used. Translational Relevance:Aira technology may provide sustained improvement in quality of life for SVI, and further study to evaluate the usefulness of this technology to assist SVI may be beneficial.

Project description:SignificanceHead-mounted low vision devices have become a viable alternative to enhance residual vision. This study supports the use of a head-mounted display to improve aspects of functional vision and quality of life. Much is still unknown regarding the required frequency, duration, or potential effectiveness of this telerehabilitation training protocol or what characteristics best identify optimal users.PurposeA randomized study explored the effect of telerehabilitation on quality of life and functional vision in individuals with low vision using a head-mounted display.MethodsWe recruited 57 participants (age, 21 to 82 years; mean, 54.5 years) among new prospective eSight Eyewear users, randomized 1:1 into two parallel groups; the experimental group received the telerehabilitation training provided by a low vision therapist, whereas the control group received the self-training standard offered by the device manufacturer and without involvement of a low vision therapist. The primary outcome measures were the impact of telerehabilitation on validated measures of assistive technology-related quality of life: the Psychosocial Impact of Assistive Devices Scale and the Quebec User Evaluation of Satisfaction with Assistive Technology scale. Exploratory outcomes were the assessment of self-reported functional vision using the Veterans Affairs Low Vision Visual Functioning Questionnaire-48 and cybersickness associated with head-mounted display use with the Simulator Sickness Questionnaire.ResultsAssistive technology-related quality of life was improved when measured by the satisfaction scale but not the psychosocial scale within the first 3 months, independently of training type. Overall, functional vision improvement was observed within the first 2 weeks of device use and maintained during the 6-month study, independently of group type. Cybersickness outcomes were similar between training groups and did not change significantly for 6 months.ConclusionseSight Eyewear, either with telerehabilitation or with the manufacturer self-training comparison, improved functional vision and increased users' quality of life within the initial 3 months of device training and practice.

Project description:Italian baseball played by visually impaired and blind athletes is an adapted team sport which maintains the peculiar fast-moving features of this popular sport. It is also a mixed team game played together with sighted subjects. Here, we performed a national survey aimed at assessing the differences in psychological well-being (PWB) and quality of life (QoL) between visually impaired baseball players from Italian teams and non-players using a structured online questionnaire. Forty-three visually impaired baseball players and thirty-four visually impaired sedentary individuals completed a structured self-report survey including the validated 18-item Italian versions of the PWB (PWB-18) scale and the Short Form-12 (SF-12) questionnaire to assess the QoL. PWB-18 and SF-12 reference data from the Italian normally sighted population were also employed for comparison with the visually impaired baseball player group. Visually impaired baseball players reported better scores in all dimensions of the PWB-18 scale and significant higher scores in both physical and mental QoL evaluated by SF-12 than the non-player group. In addition, PWB-18 scale findings revealed significant differences between visually impaired baseball players and the reference normally sighted population consisting in lower scores for autonomy, environmental mastery, positive relations with others and purpose in life dimensions. Conversely, the mean scores for PWB-18 personal growth and self-acceptance dimensions were not significantly different between the two groups. The SF-12 questionnaire results demonstrated a significantly higher physical score in visually impaired players compared with the reference population. Instead, the SF-12 mental score of visually impaired athletes tended to be lower, though this difference was not statistically significant. Collectively, our findings suggest that the practice of Italian baseball may have a positive impact on PWB and QoL of visually impaired individuals.
