Rothwell scale
The Rothwell scale, or Rothwell system, or Rothwell method, applied to incontinence care products, is a scale that shows how absorbent a particular incontinence pad or adult diaper is, and how much liquid it can absorb and hold before it is likely to leak due to overfill. The system provides a quick reference for assessing how much liquid can be held by a sheet, pad or diaper, and therefore how appropriate it will be for a particular individual in any given circumstance.
