8. The research results
A number of analysis were carried out during the study and results obtained, details of
which have been presented as in Akinladejo (2005). This chapter presents two results on two
of the patients who used the virtual environment.
8.1 Performance results
For the exercise sessions in the virtual environment, the percentage of improvement in using
the system was calculated based on the patients' performance data for the last day of week
two and that of week four on the painting exercise. That is,
LastDayData (Week2) - LastDayData (Week4) x 100 %
LastDayData (Week2)

to complete the task in the virtual environment).
