IADL Significant Why Shopping? Meaningful
Why Shopping? Importance of Practicing Shopping Task After Stroke • Many new motor and cognitive difficulties after neurological injury • Difficult to return to similar function, especially the elderly • Only small percentage of post-stroke population continues to participate in complex life tasks. • During rehabilitation, difficult to assess and practice shopping tasks at a real supermarket
Therefore we have many virtual supermarkets Virtual Supermarkets VR Desktop Based Castelnuovo , et al., 2003; Josman et al., 2008; Klinger et al., 2004; Lee et al., 2003 IREX- VMall: Video CaptureVR System Rand, et al., 2007; 2009; 2010
Virtual supermarkets IREX - VMall: Video CaptureVR System integrating & assessing motor and cognitive aspects More complex set-up needed for operation limited options of changing task complexity (Rand, et al., 2007)
Virtual Interactive Shopper different stores that can be changed & adapted integrating & assessing motor and cognitive aspects SeeMe VIS Video Capture is used without the need of chroma key background Budget Management http://www.virtual-reality-rehabilitation.com/products/seeme/what-is-seeme

Objectives • To explore the performance of shopping tasks in three different environments: a real environment, a physical mock-up and a virtual environment of post –stroke subjects as compared to healthy controls • To examine the relationship between performance of shopping tasks in the 3 environments
Rationale • The three environments (Virtual, MockUp, Real) complement one another for the purposes of assessment and treatment of performance of complex IADL tasks during the rehabilitation process • The findings will lead to better understanding of how to use VEs in clinical settings for training skills needed for participation in everyday activities
Population: 6 Healthy Adults 5 female 1 male Age (years) range: 56-77 mean ± SD: 63.5 ± 9.3 5 Inpatients After Stroke 2 female, 3 maleAge (years) range: 65-82 mean ± SD: 74.8 ± 6.6Time since stroke (months): 1-7.5 FIM: 88.4 ± 19.5 MMSE: 26.4 ± 4.8
Experimental Task “4 Items” • Original Task: (Rand et al., 2007) • List is visible during test • Performed in VIS and MockUp • Outcome measures • Time to complete test • Number of errors (wrong item, not buying an item) • Does not involve budget management. Modified Task: • Performed in all 3 environments (VIS, MockUp & Cafeteria) • Involved budget handling (Type of error if incorrect)control subject.avipost stroke subject.AVI
Results Time to complete both versions of the 4-item tests in all environments, for two groups
Performance of individuals Modified test in theMock-up and VIS Modified test in the Cafeteria and VIS
Trajectory Locations visited by one subject with stroke and one control within the virtual supermarket during the modified 4-item test Control Post-stroke
Conclusions • VIS appears to be well suited for the assessment and training of the higher cognitive abilities needed for shopping • Shopping tasks may be adapted and graded • Requires motor and cognitive aspects • VIS Performance results suggest that it is sensitive to differences between post-stroke subjects and healthy controls • Performance ability in 3 environments related • For the post-stroke group, times to complete the modified 4-item test in the VIS appear to correlate with both the times of the store mock-up and the cafeteria
Conclusions(Con’t) • Positive responses of all participants to VIS (n=11) according to Short Feedback Questionnaire -SFQ (Kizony et al., 2006) : • enjoyed the task (mean ± SD = 4.2 ± 0.9) • reported that it appeared to be realistic (mean ± SD = 4.2 ± 0.9) • Further analysis needed to discern types of errors and ability of participants to self-correct.
