In the current study, our primary objective was to evaluate the performance of individuals with tremor in operating a virtual wheelchair driving task using an IJ with WFLC filter, an IJ without a filter, and an MSJ. We hypothesized that in this environment, the subjects' performance statistics would rank from best to poorest in this order: IJ with filter > IJ > MSJ.
Subjects practiced with the IJ and MSJ for 36 trials, up to 30 min.
The IJ produced significantly lower trial times than the IJ with filter and MSJ (p = 0.0425 and p < 0.001, respectively) (Figure 6).
The IJ produced significantly fewer boundary violations than the MSJ (p < 0.001).

is commonly sold as 10mg per tablet.
