Characteristics of Sit-to-Stand from a Western-Style Toilet When Putting on Pants in Patients with Hemiplegia Who are Toilet Independent: A Preliminary Stud

Introduction: Studies of independent toileting in hemiplegic stroke patients have examined patients' ability to perform sit-to- stand (STS) motion from a Western-style toilet; however, the characteristics of the STS motion performed in conjunction with pulling up of pants (toileting) remain unclear. This study elucidated the characteristics of toileting based on the differences in the center of pressure (COP), force on the foot sole (foot force), and trunk acceleration during toileting in hemiplegic patients under conditions similar to those of daily life. Methods: Ten male hemiplegic patients participated in this study. Measurements were taken using a foot pressure distribution analysis tool and portable three-dimensional motion analysis tool. Based on video recordings, STS and toileting tasks were divided into four phases (P1–P4), and each phase was analyzed. STS and toileting tasks were evaluated and compared. Results: Eight participants exhibited “Pattern A,” which involved increased displacement of the COP toward the paretic side during toileting compared to that during STS. Two participant exhibited "Pattern B", which involved decreased displacement of the COP toward the paretic side during toileting compared to that during STS. Comparisons between STS and toileting showed that the phase from maximum dorsiflexion to full hip extension (P3) was significantly different for maximum displacement of the COP in the paretic side direction (STS, -4.7 ± 9.17; toileting, 8.6 ± 14.12; p
