More data, same problem.

This is a Zone 0 paper. An academic exercise in pattern matching. The model is clever. It learns to replicate a physiotherapist's subjective scoring. But it is just a high-tech mirror, reflecting a human opinion. The ground truth is still a qualitative scale. This is not objective measurement. It is the automation of observation. My problem is this. The paper does not change the intervention. It gives me a more granular score for a gait deficit I can already see. It does not tell me *why* the knee has reduced flexion in swing. Is it hamstring spasticity? Weak hip flexors? Poor motor planning? The number does not give me the target for treatment. On Monday, a clinician's job is unchanged. The prescription is practice. Load the system. Improve the engine. A simple stopwatch measurement of gait speed tells me more about a patient's real-world capacity and survival than a multi-item algorithmic score (source). We do not need better tools to describe the problem. We need to focus on the training that solves it.
