A Self-Help Device for One-Handed Storage of a Folding Umbrella in Its Cover

Abstract

Purpose: Individuals with limited use of one hand, such as those with hemiplegia, often struggle with handling umbrella. While automatic umbrellas can be opened and closed with one hand, storing them in their covers requires both hands. To address this issue, we developed a self-help device that stores the umbrella without rolling up the fabric. This study aims to assess user satisfaction with the device for practical use.

Methods: Thirty-two stroke participants with hemiplegia due to cerebrovascular disease were instructed to perform a task using their non-paralyzed hand: removing a folding umbrella from the self-help device, opening, and placing it back into the device. Once familiar with the task, their actions were recorded using a digital video camera. Participants then evaluated their satisfaction using the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 (QUEST 2.0). The average score for each item was calculated.

Results: The motion images showed that most participants performed the task without difficulty, and all successfully used the device. However, only a few tried again when closing the self-help device. The lowest mean score was 3.8 ± 0.9. Some participants provided encouraging feedback for improvement.

Conclusion: All participants were able to complete the task. An average QUEST 2.0 score close to 4 indicates a high level of satisfaction. These results suggest that the self-help device has a high satisfaction rate. While suggestions were made for enhancements, the device shows promise for practical use, especially with proper instruction on closing the clasp.
