Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
One treatment arms.
Arm 1: Scanning training- 3x per week for 3 weeks, Mobility training- 3 x per week for 4 weeks. All approximately 60 minutes in duration. Scanning training uses a standardised approach to teach a pattern of systematic visual search strategies, using a Neuro Vision Tech (NVT) device. Scanning skills are graded, in mobility training, from an environment that is structured and familiar to the patient, into more dynamic busy environemnts including shopping centres. This will be performed by mobility instructors from a non-governement organisation.
Intervention code [1] 2782 0
Rehabilitation
Comparator / control treatment
Participants in the control group will receive the standard therapy intervention currently available which includes mobility training and occupational therapy intervention that promotes visual scanning and scanning training. The dosage will be recorded. This group will be wait listed for the visual scanning intervention to be offered at the completion of the six month follow up.

Outcomes
Primary outcome [1] 4076 0
Mobility Assessment Course (MAC)
The MAC measures the extent to which a person visually scans and identifies hazards when walking. The MAC assesses performance on a mobility course with targets positioned on the walls along the course. Participants are scored on the number of targets they identify and the time taken to complete the course.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following consent and baseline measures particpants will be randomized.

Randomization is managed by the pharmacy department at the Repatriation General Hospital.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization is managed by the pharmacy department at the Repatriation General Hospital. A statistician external to the study will generate the random sequence using the random number generator in Microsoft Excel and created sequentially numbered, sealed envelopes containing group allocation for participants.
