The effects of changing angle and height of toilet seat on movements and ground reaction forces in the feet during sit-to-stand.
The study aimed to examine the effects of changes in the angle and height on movements and ground reaction forces in the feet. Subjects were instructed to sit and stand on different angles and heights; 0° (43 cm), 10° (51 cm), and 15° (58 cm). The motion required in this study is similar to that of standing up from sitting on a chair. The Tumble Forms Wedges (10° [8 cm], 15° [15 cm]) were placed on the toilet seat to create angles and heights at 0° (43 cm), 10° (51 cm), and 15° (58 cm). The side-to-side travel distances when the subjects stood up from sitting were 103.70±12.46 at 0° (43 cm), 96.99±12.11 at 10° (51 cm), and 99.12±12.00 at 15° (58 cm). The forward and backward travel distances when the subjects stood up from sitting were 235.93±10.60 at 0° (43 cm), 194.17±8.07 at 10° (51 cm), and 181.63±8.66 at 15° (58 cm). The ground reaction forces when the subjects stood up from sitting were 1.09±0.02 at 0° (43 cm), 1.08±0.22 at 10° (51 cm), and 1.07±0.21 at 15° (58 cm). Increases in the angle and height of the toilet seat affected forward-and-backward swaying during standing up, but did not affect the ground reaction force and side-to-side swaying.
