Area of Science:

Orthopedics
Medical Imaging
Biomedical Engineering

Background:

Scoliosis screening methods like scoliometers and Moiré topography are established.
A novel screening approach utilizing a 3D human fitting application and a specialized bodysuit has been developed.

Purpose of the Study:

To evaluate the effectiveness of a new 3D human fitting application and bodysuit for scoliosis screening.
To determine the utility of this novel method in identifying scoliosis.

Main Methods:

A prospective observational study enrolled 101 patients, categorized into non-scoliosis and scoliosis groups (mild, moderate, severe).
Trunk asymmetry was quantified using Z values derived from a 3D virtual body model.
Receiver operating characteristic (ROC) curve analysis identified the optimal Z value cutoff for detecting moderate to severe scoliosis.

Main Results:

The scoliosis group exhibited significantly higher Z values compared to the non-scoliosis group.
Patients with moderate or severe scoliosis had significantly higher Z values than those with mild or no scoliosis.
The optimal Z value cutoff was determined to be 19.9 mm, with 95.3% sensitivity and 58.6% specificity for detecting moderate to severe scoliosis.

Conclusions:

The novel 3D human fitting application and bodysuit method demonstrates potential utility in screening for moderate to severe scoliosis.
This technology offers a new avenue for scoliosis detection and assessment.
