About this trial

The aims of this exploratory research project are to customize, deploy and evaluate the preliminary efficacy of a socially assistive robot as a novel approach to motivate and encourage optimal, long-term use of new magnification devices for reading in individuals with vision loss. The goals are to promote patient acceptance, adherence and skills reinforcement to achieve proficiency in the use of the magnifier, in order to attempt to reduce visual disability while performing important daily activities, such as reading tasks. This is a high priority given the increasing prevalence of low vision, paucity of low vision rehabilitation providers, and barriers related to access to care, such as transportation and geography, all of which motivate the development of this complementary approach for the provision of additional support at home by the socially assistive robot.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Individuals with any level of vision loss due to any ocular disease,

age 18 and older,

received a magnification device(s) (i.e., hand-held optical magnifiers, portable electronic video magnifiers, some stand magnifiers and CCTVs) from the UCLA Vision Rehabilitation Center.

Disqualifiers

schedules not permitting participation in planned study sessions or visits (including planning to move or take extended vacation during study period),

inability to understand study procedures or communicate responses to visual stimuli in a consistent manner (cognitive impairment as per TICS),

substance abuse,

significant hearing loss (unable to hear communication by phone or from robot),

Treatments tested in this trial

  • Socially Assistive Robot for Low Vision Rehabilitation

    Behavioral

    A socially assistive robot will be customized to engage in dialog and conversations to motivate and encourage optimal use of new magnification devices for reading at home by individuals with vision loss.

Treatment groups

20 Participants
are divided into 2 treatment groups
Group A: Immediate RobotExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

1

Activity Inventory

questionnaire; scores will be Rasch analyzed in logic units with higher or positive scores indicating less difficulty (i.e., improvement)

Time frame
change from 1 month post-enrollment to 2-3 months after receiving the socially assistive robot

Secondary outcomes

1

MNread

reading test

Time frame
For Immediate robot: baseline, 1 month, 3 months, 6 months. For Delayed/Waitlist robot: baseline, 3 months, 6 months.
2

reading test

Time frame
baseline and monthly for 6 months
3

Geriatric Depression Scale (GDS)

questionnaire; scale ranges from 0 to 15 with higher values indicating greater depression

Time frame
baseline and monthly for 6 months
4

PANAS

questionnaire; scale ranges from 10 to 50 with higher values indicating greater positive moods

Time frame
baseline and monthly for 6 months
