[Purpose] This study compared lower garment-lifting postural control characteristics during toilet-related activities between healthy participants and a post-stroke patient, and studied changes in the stroke patient’s characteristics during rehabilitation. [Participants and Methods] Six healthy individuals and one stroke participant with right hemiparesis were asked to lift a pair of pants with the left arm while on the toilet. During the process, we measured the mean percentage of body weight (%BW) on each leg and the foot center of pressure (COP) using portable force plates. Measurements were conducted twice for the stroke participant during rehabilitation. [Results] In healthy participants, the %BW and respective COP indices for both legs were not different during lifting, but the COP sway velocity and excursion were greater in the anterior-posterior (AP) than the lateral axis in both legs. In the stroke participant, no marked change was seen in the high %BW of the non-paretic leg while lifting during rehabilitation, but both legs’ COP positional asymmetry improved on the AP axis and the COP sway velocity and excursion of the non-paretic leg increased. [Conclusion] Facilitating selective COP mobility on the AP axis of the non-paretic leg during lower garment lifting could become an effective intervention for stroke patients.
