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

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
