Gait analysis is only useable WHEN IT POINTS DIRECTLY TO 100% RECOVERY PROTOCOLS! Are you that blitheringly stupid you can't see that? This did nothing towards that!

Abstract
Gait analysis is essential in post-stroke rehabilitation but
remains time-intensive and cognitively demanding, especially when clinicians must integrate gait videos and motion
capture data into structured reports. We present OGA-AID,
a clinician-in-the-loop multi-agent large language model
system for multimodal report drafting. The system coordinates 3 specialized agents to synthesize patient movement
recordings, kinematic trajectories, and clinical profiles into
structured assessments. Evaluated with expert physiotherapists on real patient data, OGA-AID consistently outperforms single-pass multimodal baselines with low error. In
clinician-in-the-loop settings, brief expert preliminary notes
further reduce error compared to reference assessments. Our
findings demonstrate the feasibility of multimodal agentic
systems for structured clinical gait assessment and highlight
the complementary relationship between AI-assisted analysis and human clinical judgment in rehabilitation workflows
