老年患者在进行坐立运动时面临困难;因此，他们在日常生活活动中对辅助设备的依赖正在增加。然而，现有的设备不根据个人的特征提供支持。本研究旨在开发一种坐立运动辅助座椅，该座椅使用负载传感器检测用户的体重，并根据用户的体重和偏好自行调整速度以帮助用户站立。此外，我们还研究了所开发设备的可行性。开发了一种通过电动辅助患者从椅子上站起来的坐立运动装置。该装置利用载荷传感器感测座板上的载荷，并将其传送到显示器，通过该显示器，用户可以利用速度控制装置自己控制速度。为了测试其可行性，肌电肌肉激活分析竖脊肌，股四头肌，胫骨前肌，腓肠肌在坐到站的运动中使用该设备在五个健康成人。当与不使用该装置相比时，使用所开发的辅助座椅装置显著降低了左侧竖脊肌、四头肌、胫骨前肌和腓肠肌的肌肉激活，分别为37.27%、20.44%、14.50%和10.56%，右侧分别为17.98%、24.48%、32.61%和6.05%，分别该具压力感应器的辅助装置可有效协助肌肉力量及平衡能力下降的长者进行由坐转站的动作。
Elderly patients face difficulty in performing the sit-to-stand motion; hence, their dependency on assistive devices for activities of daily living is increasing. However, the existing devices do not provide support according to the individual’s characteristics. This study aimed to develop a sit-to-stand motion assistive chair that detects the user’s weight using a load sensor and assists them to stand up by adjusting the speed themselves as per their weight and preference. Additionally, we investigated the feasibility of the developed device. A device for assisting patients in the sit-to-stand motion in rising up from the chair by electrical motorization was developed. This device senses the load on the seat plate using the load sensor and transmits it to the display through which the users can control the speed themselves using the speed control device. To test its feasibility, the electromyographic muscle activation was analyzed for the erector spinae, quadriceps, tibialis anterior, and gastrocnemius muscles in the sit-to-stand motion using this device in five healthy adults. When compared with the non-use of the device, the use of the developed assistive chair device significantly decreased the muscle activation of the erector spinae, quadriceps, tibialis anterior, and gastrocnemius by 37.27%, 20.44%, 14.50%, and 10.56% on the left and by 17.98%, 24.48%, 32.61%, and 6.05% on the right, respectively. The assistive device with a pressure sensor can effectively assist elderly patients with reduced muscle strength and balance in performing the sit-to-stand motion.
