Title: The Impact of Orientation and Mobility Training on Mobility, Participation and Quality of Life in Older Adults With Visual Impairments: a Randomised Controlled Trial
Brief Summary: The purpose of this study is:

1. to develop a standardised orientation and mobility training (O\&M-training) in the use of an identification/symbol cane by older adults with low vision, and;
2. to evaluate this newly developed standardised O\&M-training with respect to effectiveness and feasibility in a randomised controlled trial.


Options:
A: Inclusion Criteria:

* Diagnosis of stroke
* Able to walk 10 metres with or without assistance
* Residual paresis in the lower limb (Fugl-Meyer Lower Limb score less than 34)
* Informed written consent.

Exclusion Criteria:

* Gait speed more than 0.8 m/s
* Patients with a premorbid (retrospective) modified Rankin Scale score of greater than 3
* Gait deficits attributable to non-stroke pathology
* Visual impairments preventing use of visual cue training (as assessed by Apple Cancellation test
* Concurrent progressive neurologic disorder, acute coronary syndrome, severe heart failure, confirmed or suspected lower-limb fracture preventing mobilization, and those requiring palliative care
* Inability to follow a three step command (as assessed by Modified mini-mental status exam).
B: Inclusion Criteria:

* Age at least 65 years old
* Bilateral AMD
* Subthreshold depressive symptoms
* At least 1 vision goal that is important yet difficult to carry out

Exclusion Criteria:

* Uncontrolled glaucoma, diabetic retinopathy, corneal dystrophy, or cataracts for which surgery within 6 months is likely will be exclusionary conditions
* Current diagnosis of depression
* Cognitive impairment
* Life-threatening illness or any other health conditions that interferes with study activities.
* Patients who have received low vision rehabilitation or home-based OT in the preceding 12 months will be excluded.
C: Inclusion Criteria:

* Age 18+
* Legal blindness (visual acuity worse than 20/200 but better than no/bare light perception, and/or visual field less than 20º, in the better eye)
* Any ocular disease diagnosis that is expected to remain relatively stable throughout a 3-6 month period
* Being healthy to the extent that participation yoga therapy would not exacerbate any existing disease conditions;
* Willingness to participate on a weekly basis for the 12-week intervention;
* Moderate to severe sleep disturbances, defined as ratings of 5 or greater on the PSQI

Exclusion Criteria:

* Significant changes to vision within the most recent 3-month period
* Inability to understand study procedures or communicate responses to visual stimuli in a consistent manner
* Clinically diagnosed or clinically significant sleep disorder (e.g., sleep apnea) or a medical or psychiatric condition (e.g., chronic pain) responsible for sleep complaints;
* Use of prescription sleep medication more than once a week for duration of the study;
* Use of other psychotropic medication;
* Current recipient of sleep disorder treatment;
* Consumption of more than 2-3 alcoholic beverages per day
* Smoking more than 10 cigarettes per day;
D: Inclusion Criteria:

* Aged 55 years or over
* Low vision
* Living independently in the community or in a home for older people
* Able to see large obstacles and to go outside for a short walk or doing groceries
* One of the following:

  1. experiencing difficulties with safely crossing a street
  2. experiencing difficulties with recognising acquaintances outdoors
  3. willing to become recognisable as being partially sighted by using the identification cane
* Written informed consent
* Orientation and Mobility training (O\&M-training) in the use of an identification cane

Exclusion Criteria:

* Cognitive impairment (a score of less than 4 on the Abbreviated Mental Test 4)
* Language or hearing problems that impede completing an interview by telephone
* Confinement to bed or possible nursing home admission that impede completion of the O\&M-training
* Permanent use of a walking aid incompatible with the use of an identification cane
* Having recently received an O\&M-training in the use of an identification cane and permanent use of this cane
