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% 的美国人在一生中的某个阶段会经历背痛。据估计，每年背部相关问题给美国经济造成的损失为 350 亿至 500 亿美元。久坐的工作会增加背部受伤的风险，而且研究表明，长时间坐着、腰椎曲度变平会增加椎间盘的压力。如果腰椎保持足够的弯曲，则可以减少背部的压力。我们开发了一种佩戴在下躯干周围的设备，将弯曲传感器固定在腰椎上，监测腰椎曲度，并在佩戴者姿势不良时向佩戴者提供振动反馈，以便佩戴者可以调整自己的姿势姿势并减轻背部压力。在第一阶段，我们确认设备的反馈可用于可靠地影响坐姿。在第二阶段，我们将对背痛的患者进行长期测试。使用我们的设备，患者将学会在坐着时保持改善的腰椎曲度，我们将研究这种改善的姿势是否可以减轻腰痛的严重程度和/或持续时间。
