A change in what gets rewarded
Healthcare has been moving, steadily and unevenly, from a model that pays for the volume of services toward one that pays for the value of outcomes. The logic is appealing: reward what actually helps patients. But it raises an obvious question that the old model could sidestep — how, exactly, do you measure the outcome?
Movement as an outcome you can see
For a large share of care, the outcome is movement. Can the patient walk farther, stand more steadily, move with less compensation than before? These are precisely the things rehabilitation and much of neurology aim to improve. Yet they have historically been documented in subjective terms that are hard to compare across patients, providers, or time. Value-based models need outcomes that are consistent enough to stand up to scrutiny.
Why objectivity is the missing piece
Objective movement data provides exactly that: standardized, quantitative measures that mean the same thing from one visit and one clinician to the next. That consistency is what makes outcomes aggregable — the foundation for demonstrating that care worked, not just that it happened. Without it, value-based arrangements are forced to lean on proxies that may not reflect what patients actually experience.
Better measurement, better incentives
When outcomes can be measured objectively, the incentives of value-based care start pulling in the right direction: toward interventions that move the metrics that matter. Reliable measurement also protects clinicians, giving them defensible evidence of the progress they deliver. As the payment model evolves, the practices best positioned will be the ones that can show their results, not just describe them.
