Abstract
In recent years, spinal disorders, spinal deformities, and scoliosis have become more frequent, especially chronic systemic inflammatory diseases, such as early-onset scoliosis, idiopathic scoliosis, and ankylosis spondylitis, which have unknown causes, insidious onset, and progressive development, resulting in irreversible spinal joint deformities and stiffness at advanced stages and high disability rates. As one of the traditional Chinese health and fitness qigong exercises, Taijiquan has the effect of strengthening the waist and kidneys, sparing the tendons and softening the body, unblocking the meridians, unblocking the qi and blood, and strengthening the body and increasing intelligence. To this end, this paper proposes a data enhancement method that uses the spine line as the control curve to deform the human contours, drawing on the moving least squares deformation method to fit a variety of scoliosis cases and increase the diversity of the dataset, thereby improving the generalisation capability of the network. The colour map and depth map information are then integrated using a four-channel method and a dual feature extraction network structure to improve the accuracy of segmentation.
Highlights
Prolonged sitting posture can bring static damage to the spine, especially prostration in the seat and various poor sitting postures, which can cause asymmetry and twisting and stretching of the muscles around the spine, making the spinal system unbalanced and causing discomfort to the shoulder, neck, and back [1]. e longer the setting time, the higher the proportion of cervical spondylitis, lumbar spondylitis, and frozen shoulder [2]
Other studies have found that spinal curvature and activity are related to physical activity and that excessive physical activity or incorrect posture during mirror physical activity may have a corresponding effect on the sagittal curvature and activity of the thoracolumbar segment of the spine, causing spinal curvature and mobility abnormalities, resulting in injury to the spine and even disease [3]
Chronic low back pain is associated with changes in the structural function of the lumbar muscles, decreased muscle strength, and structural degeneration of the lumbar spine, which can lead to low spinal stability, trunk muscle strength, explosive strength of the extensor muscles, and imbalances in flexion and extension muscle strength, resulting in varying degrees of degenerative lesions in the morphology and structure of the lumbar segment of the spine and surrounding tissues [4]
Summary
Prolonged sitting posture can bring static damage to the spine, especially prostration in the seat and various poor sitting postures, which can cause asymmetry and twisting and stretching of the muscles around the spine, making the spinal system unbalanced and causing discomfort to the shoulder, neck, and back [1]. e longer the setting time, the higher the proportion of cervical spondylitis, lumbar spondylitis, and frozen shoulder [2]. In the first four postures, the upward and downward stretching and rotation of the two hands on the sky, the left and right open bow, the one-handed symmetrical pressing and lifting, and the rotating back look lengthen the muscles, ligaments, and joint tissues around the joints of the trunk and upper limbs and exercise the small joints and muscles between the vertebrae in the spine, enhancing the flexibility and stability of the spine, and increasing the contraction force of the muscles involved in movement around the neck and shoulder joints, as well as the range of neck movement. It can effectively prevent and treat scoliosis, cervical spondylosis, rotational misalignment of the thoracic spine, and lumbar back strain, as well as correcting small joint misalignments, improving neck mobility, and changing the physiological curvature of the spine [11]
