User-centered practicability analysis of two identification strategies in electrode arrays for FES induced hand motion in early stroke rehabilitation

Table 4 Used options in the semi-automatic search and automatic search for each patient

3	circular, ellipsoid, rectangular	x	no	yes	x	no
4	circular	circular, rectangular	no	no	no	no
5	circular	circular	no	yes	yes	yes (VE₂)

The term combined VEs refers to the option of combining VEs with different positions to one active VE. The term Wrist stabil. on relates to the option of using the identified VE₂ for wrist stabilization during the search in the flexor array. In the automatic search, there existed the option on defining customized VE, which were not ranked in the top five VE for a desired hand posture. For patient 3, the flexor array was not utilized. The corresponding entries are therefore marked with an ’x’
