What is physiologic capacity?
Short answer
Physiologic capacity is the amount of demand — physical, cognitive, sensory, emotional — that your body and brain can currently handle without symptoms flaring or recovery stalling.
More detail
Every system has a working range. When demand stays within that range, function is stable. When demand exceeds capacity, the body pays for it later with fatigue, symptom flares, poor sleep, or delayed recovery.
In complex or slow-recovery cases, treatment aims first to match activity to current capacity, then to gradually expand that capacity. Ignoring capacity leads to a cycle of pushing, crashing, and losing ground.
When evaluation may be appropriate
If recovery is stalling, fluctuating, or getting worse with activity, an evaluation that factors in capacity — not just the original injury — is worthwhile.
