Functional Oral Intake Scale

Also written as: FOIS — Functional Oral Intake Scale

Seven-level ordinal scale measuring functional oral intake of food and liquid for patients with dysphagia.

Full Definition

The Functional Oral Intake Scale (FOIS) is a validated seven-point ordinal scale that documents the functional level of oral intake in patients with dysphagia. Ranging from Level 1 (no oral intake) to Level 7 (normal oral intake with no restrictions), the FOIS provides a standardized method for tracking changes in functional swallowing ability over time. This outcome measure is particularly useful for documenting progress in dysphagia therapy and communicating functional status across healthcare settings and disciplines.

Usage

Usage note: Capitalize all major words in the full term. FOIS is acceptable after first reference.
