The method employs a second-order regression model to establish a mapping between the posture data measured by the device and the true spinal alignment obtained from X-ray images, thereby deriving subject-specific calibration parameters that effectively enhance the accuracy of spinal posture estimation.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1-1024x518.png\" alt=\"\" class=\"wp-image-929\" width=\"842\" height=\"426\" srcset=\"https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1-1024x518.png 1024w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1-300x152.png 300w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1-768x388.png 768w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1-200x101.png 200w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/diff-1.png 1527w\" sizes=\"auto, (max-width: 842px) 100vw, 842px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image-1024x433.png\" alt=\"\" class=\"wp-image-926\" width=\"1097\" height=\"464\" srcset=\"https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image-1024x433.png 1024w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image-300x127.png 300w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image-768x325.png 768w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image-200x85.png 200w, https:\/\/ldsc.pme.nthu.edu.tw\/wp-content\/uploads\/2025\/10\/image.png 1328w\" sizes=\"auto, (max-width: 1097px) 100vw, 1097px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"ast-oembed-container\" style=\"height: 100%;\"><iframe loading=\"lazy\" title=\"The setup processes for the original and enhanced designs of wearable spinal measurement devices.\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/MpCLu3YNmCM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><figcaption class=\"wp-element-caption\"><strong>Demonstration of the wearing procedure for the active and passive versions of the device<\/strong><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"ast-oembed-container\" style=\"height: 100%;\"><iframe loading=\"lazy\" title=\"Design and Optimization of a Wearable Under-actuated Mechanism for Spinal Posture Measurement\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/JbkmydaVIsI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><figcaption class=\"wp-element-caption\"><strong>Functional demonstration of the proposed device<\/strong><\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This study presents a novel 12-degree-of-freedom underactuated wearable device specifically designed for continuous, noninvasive monitoring of spinal posture in nonclinical environments.
