The condition of elder using walker standing up and sitting down

Researchers of assist device—walkers have often suggest that safety and assist low limb injury elders is important. However, research which has empirically documented the link between using walker cause upper limb injury is scant. Therefore, the aim of this study attempts to explore how the wrist deviation and vertical force among elderly individuals using a walker for assistance to stand up and sit down. This research involved the experiment, 17 elderly males and 17 elderly females voluntarily participated in this experiment. The Analysis of this study was conducted through One-sample t-test, two independent sample t-test, and Pearson product-moment correlation in order to indicate the wrist deviation and vertical force while elders use horizontal handles operating walker. The results of analysis showed that walker in the market do indeed causes dorsal extension of users’ wrists during usage, especially in a standing position with an average of 27.04 degrees. Between standing up and sitting down, there is no significant different in wrist deviation, neither does largest vertical force. Gender does affect the largest vertical force both in standing up and sitting down. The male users exerted more vertical force than female users did. A correlation between weight and the vertical force was observed. The heavier subjects exert larger vertical force when standing up and sitting down.
