“…Congenital or acquired loss of vision leads to the development of abnormal sensory and motor interactions that result in the development of typical musculoskeletal deformities; these then lead to faulty gait patterns, which cause disability (Alotaibi, Alghadir, Iqbal, & Anwer, 2016;Barlow, 1955;Nakamura, 1997). People with visual impairment are unable to perform their daily activities, become dependent, and experience poor quality of life (Markowitz, 2006).…”

BackgroundThe visual system enables the brain to assess information regarding the position of the body in space. Congenital or acquired blindness leads to the development of abnormal sensory‐motor interactions that results in development of typical musculoskeletal deformities and gait patterns that cause disability. Diabetes and related complications are expected to increase exponentially in the next 10 years; thus, the number of people with visual impairment is expected to increase. However, there have been few studies regarding etio‐pathogenesis of postural alteration and balance impairment in people with visual impairment; moreover, no previous study has investigated postural stability in this population. This study aimed to assess the center of gravity (COG) velocity in subjects with visual impairment and compared with that in sighted subjects.MethodsSeventy male subjects, 20–40 years of age, participated in this study; they were divided into sighted (control) and visually impaired groups. COG velocity while standing on an unstable surface was measured using the NeuroCom® Balance Master Version 8.5.0. For the sighted group, data were recorded with eyes open and then with eyes closed. For the visually impaired group, no instructions were given with respect to eyes during data collection.ResultsMean COG velocity was significantly higher in the visually impaired group than in the sighted group with eyes open. However, there was no difference in mean COG velocity between the visually impaired group and the sighted group with eyes closed. The difference in mean COG velocity between sighted subjects with eyes open and eyes closed was also significant. Mean COG velocity while standing on a foam surface varied among visually impaired subjects and sighted subjects with eyes open and closed.ConclusionThis study showed that subjects with visual impairment, regardless of eye opening or closure, behave in the same manner as sighted subjects with eyes closed.

“…For those people having impaired vision, many vision-dependent activities and daily tasks are difficult or impossible to perform, reducing their ability to perform ADL and independence, which has a negative impact on their quality of life22 ) . With the progression of vision loss, walking speed slows and the frequency of collision with obstacles increases, and daily living activities such as walking become impossible23 ) .…”

[Purpose] This research investigated the relationship between balance measured by a TETRAX and activities of daily living (ADL) assessed by NEI-VFQ 25. The results should provide basic data for rehabilitation therapy for low-vision patients. [Methods] We used the NEI-VFQ-25 vision-related Activities of Daily Living evaluation, MMSE-K, and TETRAX to evaluate 30 low-vision outpatients at K hospital in Daejeon, South Korea from July 5 to July 23, 2012. We performed linear regression analysis using a statistical significance level of 0.05. [Results] Balance in the normal eyes open (NO) posture correlated with the normal eyes closed posture and age, but showed no correlation with NEI-VFQ 25. The ADL level correlated with monocular vision, female gender, cognition, and NO posture. These variables explained 54.4% of the aspects of their ADL. [Conclusion] This research proves that low vision adversely affects balance ability, and is influenced by type of vision, gender, and cognitive assessment.

“…LVR typically involves rehabilitation therapy (training and education) and vision assistive equipment (VAE). Standards of care have been published for the main professions that provide LVR services: ophthalmology, optometry, vision rehabilitation therapy, and occupational therapy[13–15]. Yet considerable variability exists in the models of care and breadth of services provided by outpatient LVR clinics[16].…”
