Physical activity interventions for adults who are visually impaired: a systematic review and meta-analysis

Abstract

ObjectivesCompared with sighted individuals, people with visual impairment have a higher prevalence of chronic conditions and lower levels of physical activity. This review aims to systematically review physical activity interventions for those with a visual impairment and to assess their effectiveness.DesignA systematic review of articles reporting physical activity interventions in visually impaired individuals was conducted. Medline, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus and the Physiotherapy Evidence Database were searched in August 2018. Meta-analyses were conducted on randomised controlled trials with the same outcome measure.SettingMost interventions were conducted in a group setting, with some including an at-home, self-directed component.ParticipantsFollowing identification of a recent systematic review of physical activity interventions in children, our review focused on adults aged 18 years and older with a visual impairment.Primary and secondary outcome measuresOutcomes included measures of balance, mobility, mental well-being (eg, quality of life), number of falls, muscle strength, flexibility and gait.ResultsEighteen papers from 17 studies met inclusion criteria. Physical activity components include falls prevention and/or balance-based activities, walking, tai chi, Alexander Technique, Yoga, dance, aerobics and core stability training. Significant results in favour of the intervention were reported most commonly in measures of functional capacity (9/17 studies) and in falls/balance-related outcomes (7/13 studies). The studies identified were generally small and diverse in study design, and risk of bias was high across several categories for most studies. Meta-analyses indicated non-significant effects of the included interventions on the Timed Up and Go, Chair Sit Test and Berg Balance Scale.ConclusionsPhysical activity interventions in individuals with visual impairment incorporating activities such as tai chi, Yoga and dance can have positive results, particularly in physical measures such as mobility and balance. However, when performing a meta-analysis of randomised controlled trials, the evidence for effectiveness is less clear. More studies with larger sample sizes, stronger designs and longer follow-up periods are needed.PROSPERO registration numberCRD42018103638.

Is social participation associated with good self-rated health among visually impaired older adults?: the JAGES cross-sectional study

“…On the other hand, individuals with visual impairment have been reported to have a fear of falling due to low visual function, and therefore, to spend less time engaged in moderate–vigorous physical activity (26–48%) compared to individuals without visual impairment [ 43 , 44 ]. In many cases, in fact, visual impairment is the exclusion factor for physical activity interventions [ 45 ]. However, a systematic review [ 45 ] illustrated that physical activity interventions for adults with visual impairment, such as Tai chi, Yoga, and dance, could have positive results, particularly in physical measures such as mobility and balance.…”

Designing an internet‐based intervention for improving wellbeing in people with acquired vision loss: A Delphi consensus study

“…Another possible reason is the concern about hazards such as uneven, slippery or blocked footpaths when navigating outside 88 . Other barriers to physical exercise include medical problems, lack of transport or time and inflexibility within the exercise programme 89 . A physical wellbeing intervention could help overcome these barriers associated with face‐to‐face exercise and leisure activities.…”

“…A physical wellbeing intervention could help overcome these barriers associated with face‐to‐face exercise and leisure activities. A section regarding ways to increase physical exercise safely for people with VI was suggested because of the positive effects it has on health and well‐being 89 . Stakeholder responses on the survey strongly advocated the need for good mobility and orientation training.…”

Effects of Exercise Programs on Anxiety in Individuals with Disabilities: A Systematic Review with a Meta-Analysis

“…Although the benefits of PE are clear and evident for the general population, namely, in the reduction anxiety symptoms, the effects in the population with disabilities are still unclear and have not been evaluated, and researchers usually direct their interests to other variables [28][29][30][31]. It is important to understand if they are transversal to the population with disabilities in order to promote their quality of life, related to the conceptual model of Schalock et al [32], being a construct divided into three dimensions: (i) Independence, (ii) social participation, and (iii) well-being.…”
