Description
Measuring how a child with Guillain-Barré syndrome walks usually takes a motion lab the clinic does not have. Yu-Sun Min tested a pocket alternative in 2025: two smartphones filming the child, with software that turns video into three-dimensional joint angles, no markers on the body. Two cases carry the proof of concept.
One boy's swing and push-off faults, tied to a treatment-related relapse, visibly eased alongside strength and balance gains over six weeks of rehab. A girl with normal strength still showed stiff hip and knee motion the angles caught, matching her balance disorder. Every session fit inside routine clinic time. Min proposes the setup as a low-cost digital biomarker for recovery.
