Name and SynonymsProlo Scale, Prolo Economic Scale, Prolo Score
Prolo D, Oklund SA, Butcher M (1986) Toward uniformity in evaluating results of lumbar spine operations. A paradigm applied to posterior lumbar interbody fusions. Spine 11(6):601–606.
This is a 10-point scale consisting of only two questions evaluating the functional and economic status of the patient. It can be described as an outcome disability tool (originally designed for use as an outcome measurement for patients in whom underwent posterior lumbar interbody fusions) measures economic and functional status of the patient before and after treatment.
The scale below is modified for cervical myelopathy patients.
Scoring Method and InterpretationThe lower the score the more severe the deficits. Normal function: 9 + 10, grade 1: 7 + 8, grade 2: 5 + 6, grade 3: 2–4.
Weight of the criterion in percentage of 10 points: economic status 50%; functional status 50%
There is also a modified Prolo scale frequently for use in patients in whom underwent cervical operative procedures.
Scientific Spine's Comment
Because of the simplicity of the scale, it may not tell the full story because there is no pain scale or analgesic usage incorporated into the scale.
