Standing ability
SCES
In the first phase of the study, with SCES on, 0772 did not need to use his upper extremities for balance self-assistance in a standing position. In contrast when SCES was off, he needed to hold the parallel bars and use his upper extremities to self-assist balance. However, 0772 required maximal knee assistance and moderate hip assistance from study staff to stand in parallel bars whether SCES was on or off, and this persisted throughout the whole study. Despite this, during the interim mapping process (following the first phase of the study) when configurations for standing were refined, 0772 demonstrated volitional trunk and hip control while in a semi-standing position, supported in the standing frame; further details are provided in Fig.
