Brief summary

Visual loss following stroke impacts significantly on activities of daily living and is an independent risk factor for becoming dependent. Routinely, allied health clinicians provide training for visual field loss, mainly with eye movement based therapy. The effectiveness of the compensatory approach to rehabilitation remains inconclusive largely due to difficulty in validating functional outcome with the varied type and dosage of therapy received by an individual patient. This study aims to determine which treatment is more effective, a standardized dosage approach or individualized therapy in patients with homonymous hemianopia post stroke.

Interventions

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
