DESCRIPTION (provided by applicant): Nearly 70% of the United States population will experience back pain at some point in their lives. The annual cost to the United States economy of back-related problems has been estimated at between $35 Billion and $50 Billion. Sedentary jobs have been linked to an increased risk of back injury, and it has been shown that sitting for prolonged periods with a flattened lumbar curvature increases the stress on intervertabral discs. Stress on the back can be reduced if the lumbar spine remains sufficiently curved. We have developed a device that is worn around the lower torso, holds a bend sensor to the lumbar spine, monitors lumbar curvature, and provides vibrational feedback to the wearer when the wearer is in a poor posture so that the wearer can modify his or her posture and reduce the stress on his or her back. In Phase 1 we confirmed that feedback from the device can be used to reliably influence seated posture. In Phase 2 we will carry out long term tests on patients who experience back pain. Using our device, patients will learn to maintain improved lumbar curvature while sitting, and we will investigate whether this improved posture reduces the severity and/or duration of lower back pain.

描述（由申请人提供）：近70%的美国人口将在他们的生活中的某个时候经历背痛。据估计，美国经济每年因背部相关问题造成的损失在350亿美元至500亿美元之间。久坐不动的工作与背部受伤的风险增加有关，并且已经表明，长时间坐着，腰椎弯曲变平会增加椎间盘的压力。如果腰椎保持足够的弯曲，背部的压力可以减少。我们已经开发了一种设备，该设备被穿戴在下躯干周围，将弯曲传感器保持到腰椎，监测腰椎弯曲，并且当穿戴者处于不良姿势时向穿戴者提供振动反馈，使得穿戴者可以修改他或她的姿势并减少他或她的背部上的压力。在第1阶段，我们证实了来自设备的反馈可以用来可靠地影响坐姿。在第二阶段，我们将对患有背痛的患者进行长期测试。使用我们的设备，患者将学会在坐姿时保持改善的腰椎弯曲，我们将研究这种改善的姿势是否会降低下背痛的严重程度和/或持续时间。
