Development and Evaluation of a Body Mapping Tank-Top for Early Stage Scoliosis Treatment in Adolescents

Scoliosis is an abnormal curvature of the spine, usually characterized by an S or C-shaped curvature in the normal coronal plane (viewed from the back). This lateral curvature may cause rotation and twisting of the spine, resulting in an asymmetrical back and potentially leading to many related physical problems. Idiopathic scoliosis, which accounts for about 80% of scoliosis cases, is the most common type. It may be associated with the interaction of polygenic inheritance, family aggregation, and environmental factors. Teenagers with spinal curvature between 10–20 degrees are considered to be in the early stages of scoliosis. It is recommended that hard braces be used for treatment in teenagers with a spinal curvature between 21 and 40 degrees. However, hard braces are often criticized for their uncomfortable fit and unsightly appearance, which can somewhat affect the treatment outcome. Nowadays, as teenagers increasingly use electronic products and develop poor standing and sitting habits, more environmental factors are triggering the onset of scoliosis. To prevent the disease from worsening, early diagnosis and effective treatment have become particularly important. Therefore, our team has developed an innovative body mapping tank top for adolescents with early-stage scoliosis. Equipped with 3-axis accelerometer sensors synchronized with surface electromyography (sEMG) signals, and combined with home-based posture training programme developed by our team, it can improve patient’s daily posture and prevent curve progression for teens with early scoliosis.
