| Summary: | 碩士 === 國立臺北科技大學 === 創新設計研究所 === 103 === Older people often struggle for sit-to-stand (STS), including from bedside. In addition to decline of muscle strength and postural control, there are joint stiffness pain or positional vertigo, which could cause the occurrence of falls. The purpose of this study is to provide older people with strategies and assistive devices for standing up from bedside, and enhance conditions for independent living.
Through the literature review and analysis of existing assistive devices, the difficulties of standing up from bedside were collected. One of the significant findings indicated that the seat-off occurrence is the determinants of STS movement performance.
This study intended to formulate Single Forearm Support (SFS) strategy for the elderly during sit-to-stand transfer. Functional experiments were carried out to validate the operation and effectiveness of the single forearm support (SFS) strategy. Sequential ground reaction forces were recorded to evaluate the effects of weight shifting to the supporting single forearm during STS movement, especially at the seat-off occurrence.
Research findings: (1) Employing Single Forearm Support (SFS) strategy in the task of sit-to-stand (STS) from bedside, the peak of ground reaction force was significantly reduced at the seat-off occurrence which is the determinants of STS movement performance. (2) Single Forearm Support (SFS) strategy provided stable support of balance during STS transfer. (3) The height of forearm supporting board is suggested to set 2 to 6 cm higher than user’s elbow.
As a result, Single Forearm Support (SFS) strategy enhances independent living and enable older people to standup from bedside effortlessly, stably, and reducing the burden on knees.
