In-Depth Information
All the patients could not complete the four different levels of the VR task during the first
week of the exercise. However, at the end of the second week, their performances had
improved, and they were all able to complete the tasks at all the levels. Results from the
analysis of the exercise data of the last day of week two and the last day of week four as in
table 1 and 2 show that patient EO2 made the most improvement on the VR task(i.e. spent
less time completing the task), while patient LP3 made the least improvement. EO2
diligently studied the painting movement and acquired the method of the painting process
during the implementation period, hence the result. LP3, however, struggled until the last
week before he started improving on the painting process. This result is significant to their
functional gains as explained subsequently.
8.2 The clinical results
The gait variables of the patients were captured using the Polhemus Electromagnetic
Tracker System before and after the intervention using the virtual environment, and
Kaltenborn's convention (Akinladejo, 2005) was used to interpret the results. The graphs
below were obtained for the two of the patients.
