The Hand Extension Robot Orthosis (HERO) Grip Glove was iteratively designed to meet requests from therapists and persons after a stroke who have severe hand impairment to create a device that extends all five fingers, enhances grip strength and is portable, lightweight, easy to put on, comfortable and affordable.
Eleven persons who have minimal or no active finger extension (Chedoke McMaster Stage of Hand 1-4) post-stroke were recruited to evaluate how well they could perform activities of daily living and finger function assessments with and without wearing the HERO Grip Glove.
The 11 participants showed statistically significant improvements (p < 0.01), while wearing the HERO Grip Glove, in the water bottle grasp and manipulation task (increase of 2.3 points, SD 1.2, scored using the Chedoke Hand and Arm Inventory scale from 1 to 7) and in index finger extension (increase of 147, SD 44) and range of motion (increase of 145, SD 36). The HERO Grip Glove provided 12.7 N (SD 8.9 N) of grip force and 11.0 N (SD 4.8) of pinch force to their affected hands, which enabled those without grip strength to grasp and manipulate blocks, a fork and a water bottle, as well as write with a pen. The participants were 'more or less satisfied' with the HERO Grip Glove as an assistive device (average of 3.3 out of 5 on the Quebec User Evaluation of Satisfaction with Assistive Technology 2.0 Scale). The highest satisfaction scores were given for safety and security (4.6) and ease of use (3.8) and the lowest satisfaction scores were given for ease of donning (2.3), which required under 5 min with assistance. The most common requests were for greater grip strength and a smaller glove size for small hands.
The HERO Grip Glove is a safe and effective tool for enabling persons with a stroke that have severe hand impairment to incorporate their affected hand into activities of daily living, which may motivate greater use of the affected upper extremity in daily life to stimulate neuromuscular recovery.
手伸展机器人矫形器（HERO）握手套经过反复设计，以满足治疗师和手部严重受损的中风患者的要求，旨在制造一种可伸展所有五个手指、增强握力、且便携、轻巧、易于穿戴、舒适且价格合理的设备。
招募了 11 名手部损伤最小或无主动伸展的中风后患者（Chedoke McMaster 手部阶段 1-4），评估他们在佩戴和不佩戴 HERO 握手套时，日常生活活动和手指功能评估的表现。
11 名参与者在佩戴 HERO 握手套时，在水瓶抓握和操作任务（Chedoke 手和手臂库存量表评分从 1 到 7 增加 2.3 分，标准差 1.2）和食指伸展（增加 147，标准差 44）和运动范围（增加 145，标准差 36）方面表现出统计学上的显著改善（p<0.01）。HERO 握手套为他们的患手提供了 12.7N（标准差 8.9N）的握力和 11.0N（标准差 4.8N）的捏力，使那些没有握力的人能够抓握和操作积木、叉子和水瓶，并使用钢笔书写。参与者对 HERO 握手套作为辅助设备“或多或少满意”（Quebec 用户对辅助技术满意度评估 2.0 量表的平均评分为 3.3 分）。满意度最高的是安全性和稳定性（4.6）和易用性（3.8），而最不满意的是穿戴方便性（2.3），需要在辅助下不到 5 分钟。最常见的要求是更大的握力和更小的手套尺寸，以适应小手。
HERO 握手套是一种安全有效的工具，可使手部严重受损的中风患者将其患手融入日常生活活动中，这可能会激励他们在日常生活中更多地使用患侧上肢，以刺激神经肌肉恢复。
