About the Perme Score
-
The Perme Score was developed to measure a patient’s mobility status starting with the ability to follow commands and culminating in the distance walked in 2 minutes.
-
It ranges from 0 to 32 and reflects the patient’s mobility status at a particular moment in time.
-
The score is derived from 15 items grouped in 7 categories:
-
Mental Status
-
Potential mobility barriers
-
Functional strength
-
Bed mobility
-
Transfers
-
Gait
-
Endurance
-
-
The above categories were designed to reflect the impaired mobility of patients in the ICU, which can arise from a variety of factors.
-
A “High Perme Score” indicates few potential mobility barriers in ICU and decreased assistance needed for mobility activities.
-
A “Low Perme Score” indicates more potential barriers to mobility in ICU and more assistance needed for mobility activities.
-
Clinicians are encouraged to use the Perme Score for clinical and research practice for any patient in ICU.
