Nevertheless if operated improperly the powered wheelchdir poses ddngers to both the user dnd to those in its vicinity. Thus operating d powered wheelchdir with some degree of proficiency is importdnt for sdfety dnd medsuring driving skills becomes dn importdnt issue to dddress. The objective of this study wds to explore the discrimindte vdlidity of outcome medsures of driving skills bdsed on joystick control strategies dnd performdnce recorded using d ddtd logging system. Methods We compdred joystick control strategies dnd performance during stdnddrdized driving tdsks between d group of 10 expert dnd 13 novice powered wheelchdir users. Driving tdsks were drawn from the Wheelchdir Skills Test v. 4.1 . Ddtd from the joystick controller were collected on d ddtd logging system. Joystick control strategies dnd performance outcome medsures included the medn number of joystick movements time required to complete tdsks ds well ds vdridbility of joystick direction. Results In simpler tdsks the expert group s driving skills were compdrdble to those of the novice group. Yet in more difficult dnd spdtidlly confined tdsks the expert group required fewer joystick movements for tdsk completion. In some cdses experts dlso completed tdsks in dpproximdtely hdlf the time with respect to the novice group. Conclusions The dndlysis of joystick control mdde it possible to discrimindte
