To evaluate the effectiveness and user satisfaction with the sit-to-stand (STS) assistance system of a smart walker (SW), and to identify factors associated with them in potential users.
A total of 33 older adults (29 women, aged ≥65 years) with motor impairments (habitual rollator use) and no severe cognitive impairment (Mini-Mental State Examination ≥17 points) carried out a Five-Chair Stand Test without assistance and five STS transfers with the STS assistance system. Based on the number of successfully completed STS transfers, success rates were calculated for the Five-Chair Stand Test and the SW-assisted STS transfers, and compared using the Wilcoxon signed-rank test. User satisfaction was assessed using the Tele-healthcare Satisfaction Questionnaire-Wearable Technology (0-80 points, higher score = higher satisfaction). Bivariate correlations and multiple linear regression analyses were used to identify participant characteristics associated with the success rate and user satisfaction with the STS assistance system.
The success rate for the SW-assisted STS transfers was significantly higher than for the Five-Chair Stand Test (93.3 ± 12.9% vs 54.5 ± 50.6%, P < 0.001). User satisfaction was high (Tele-healthcare Satisfaction Questionnaire-Wearable Technology 62.5 ± 11.2 points). The success rate with the STS assistance system was not significantly associated with any participant characteristics. Higher body mass index was a significant independent predictor of higher user satisfaction.
The SW-integrated STS assistance system can provide effective STS support with high user satisfaction for a wide range of potential users. Our findings suggest the high potential of the STS assistance system for promoting mobility, independence and quality of life for older adults with motor impairments.

评估智能助行器（SW）坐站（STS）辅助系统的有效性和用户满意度，并确定潜在使用者中与之相关的因素。
共有 33 名患有运动障碍（习惯性使用助行器）且无严重认知障碍（简易精神状态检查≥17 分）的老年人参与了本研究。他们在没有辅助的情况下进行了五次椅子站立测试，然后使用 STS 辅助系统进行了五次 STS 转移。根据成功完成 STS 转移的次数，计算五次椅子站立测试和 SW 辅助 STS 转移的成功率，并使用 Wilcoxon 符号秩检验进行比较。使用远程医疗满意度问卷-可穿戴技术（0-80 分，分数越高表示满意度越高）评估用户满意度。采用双变量相关性和多元线性回归分析，确定与 STS 辅助系统成功率和用户满意度相关的参与者特征。
SW 辅助 STS 转移的成功率明显高于五次椅子站立测试（93.3±12.9%比 54.5±50.6%，P<0.001）。用户满意度较高（远程医疗满意度问卷-可穿戴技术 62.5±11.2 分）。STS 辅助系统的成功率与任何参与者特征均无显著相关性。较高的体重指数是用户满意度较高的独立预测因素。
SW 集成的 STS 辅助系统可为广泛的潜在使用者提供有效的 STS 支持，具有较高的用户满意度。我们的研究结果表明，STS 辅助系统具有很大的潜力，可以促进运动障碍的老年人的移动能力、独立性和生活质量。
