PotsiApp is a medical tool designed to assist in the assessment of spinal deformity by calculating the Posterior Trunk Symmetry Index (POTSI). The app aims to identify frontal plane asymmetry that may indicate scoliosis, serving as a supplementary tool for clinical physical examinations. ## Key Features - **POTSI Index Calculation**: Calculates the Posterior Trunk Symmetry Index to evaluate spinal deformity through topographic parameters. - **Height Asymmetry Index (HAI)**: Computes height differences between shoulders, axillary folds, and waist creases to assess asymmetry. - **Frontal Asymmetry Index (FAI)**: Integrates frontal plane data to contribute to the overall POTSI score. ## Who is it for? Healthcare professionals and clinicians involved in the screening and evaluation of spinal deformities. ## Links - [App Store](https://apps.apple.com/us/app/potsiapp/id1451461437?uo=4) - [Full Intelligence Report](https://marlvel.ai/apps/potsiapp) --- *This is an overview report.
