Study type
Description of intervention(s) / exposure
Patients are randomly assigned to experimental / control groups. Experimental subjects undergo prism adaptation (PA) training for five sessions over two weeks in addition to usual care. (PA training consists of 30 reaches for targets while wearing 15 degree right deviating prism glasses.)
Double blinded FIM and Catherine Bergego Scale scores are assessed on hospital admission and discharge.
Additional tests include: letter cancellation, figure copying, TUGT walking test, seated reach test, and Fluff test.
Mailed survey follow up at 4 months includes Stroke Impact Scale (SIS-16) and depression screening (CESD-10).

Comparator / control treatment
Control subjects complete the identical procedure but wear sham coloured glasses.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group assignment sequence is generated by Excel random number generation, with results recorded in individual sealed envelopes supplied to each participating hospital. Sequence is concealed until subjects have enrolled in the study and completed all baseline assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Group assignment sequence is generated by Excel random number generation in blocks.
Masking / blinding
Blinded (masking used)

Brief summary
This study will clarify the effectiveness of prism adaptation treatment for stroke patients with hemi-spatial neglect. The treatment group will undergo five training sessions while wearing prism glasses. The control group will undergo the same procedure while wearing sham glasses. The two groups will be compared for improvements in the neglect impairment and in functional abilities.
