A brain injury can damage the brain, so that it no longer receives information about the space around one side of the world. If this happens, people may not be aware of anything on one side, usually the same side they also lost their movement (the most affected side). This severe condition is called spatial neglect. Currently there is no recommended diagnostic test or clinically-proven treatment for the condition. In a recent study, the investigators found a long-lasting reduction in neglect if people practiced picking-up an object with their unaffected hand. This intervention is called Spatial Inattention Grasping Home-based Therapy (SIGHT). It requires people to lift wooden rods of different lengths. Once a person is familiar with the task, they can practice on their own at a time convenient to them in their homes. The investigators have developed the first computerized version of SIGHT (c-SIGHT) as well as a novel diagnostic test for neglect using portable low-cost motion-tracking technology that can be used in the patient's home. In the proposed study, the investigators will investigate how usable and acceptable this technology is in people's homes. Stroke survivors (recruited from community settings) will undergo a 7-day self-led training at their homes with c-SIGHT. At the end of the intervention, 1:1 semi-structured interviews will be carried out with both stroke survivors and carers to investigate usability and acceptability of c-SIGHT. Moreover, spatial neglect, carer burden and motor function will be assessed pre- and post-completion of c-SIGHT.

C-SIGHT will be self-administered at people's homes. c-SIGHT is a computerized therapy administered via people's television. The therapy involves performing repeated rod lifts with the less impaired arm in response to auditory and visual instructions presented on the television screen connected to a laptop. A small motion-tracking camera monitors rod lifts during therapy sessions. People will be asked to self-administer c-SIGHT for 1 hour a day (30min after breakfast and 30min after lunch) for 7 consecutive days. The first day of therapy will be performed with a therapist there for training purposes.

RECRUITINGBehavioral Inattention Test (BIT) conventional sub tests
Standardized measure of spatial inattention
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Line bisection Test
Test for spatial inattention which measures spatial biases when marking middle of 10 20mm lines. Bisection error bigger that 6mm is considered evidence of spatial inattention.
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Broken Hearts test from Oxford Cognitive Screening (paper version)
Standardized measure of spatial inattention
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Computerized extrapersonal neglect test (CENT)
Computerized test measuring ego and allocentric neglect sub types in extra personal space via television screen
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Catherine Bergego Scale
Standardized checklist to detect presence and degree of unilateral neglect during observation of everyday life situations. The scale also measures self-awareness of behavioral neglect (anosognosia). The CBS uses a 4-point rating scale to indicate the severity of neglect for each item: 0 = no neglect 1. = mild neglect (patient always explores the right hemispace first and slowly or hesitantly explores the left side) 2. = moderate neglect (patient demonstrates constant and clear left-sided omissions or collisions) 3. = severe neglect (patient is only able to explore the right hemispace) This results in a total score out of 30. Azouvi et al. (2002, 2003) have reported arbitrary ratings of neglect severity according to total scores: 0 = No behavioral neglect 1-10 = Mild behavioral neglect 11-20 = Moderate behavioral neglect 21-30 = Severe behavioral neglect
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Pinch and grip force task (dynamometer)
Measures upper limb function
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Caregiver Burden Scale
To assess perceived burden among people caring for others with disabilities. There are 22 items in which the carer rates perceived burden from 0 (never) to 4 (nearly always). A total score of 0 to 20 = little or no burden; 21 to 40 = mild to moderate burden; 41 to 60 = moderate to severe burden; 61 to 88 = severe burden.
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
Stroke Specific Quality of Life Scale (SS-QOL)
A patient-centered outcome measure intended to provide an assessment of health-related quality of life (HRQOL) specific to patients with stroke. Patients must respond to each question of the SS-QOL with reference to the past week. It is a self-report scale containing 49 items in 12 domains. Items are rated on a 5-point Likert scale. Higher scores indicate better functioning. The SS-QOL yields both domain scores and an overall SS-QOL summary score. The domain scores are unweighted averages of the associated items while the summary score is an unweighted average of all twelve domain scores.
Time frame: Change from baseline (T0) to 7 days (pre-treatment baseline, T1) and from T1 to immediately after 7 days of therapy (T2)
