Objective[edit | edit source]
The Olerud-Molander Ankle Score (OMAS) is a self-reported outcome measure that assesses the symptoms and function of a patient following an ankle fracture. This scoring system was developed by Olerud and Molander in 1984 as a fast, easy and objective way to determine the impact of ankle fracture on the patient's current status.[1]
Intended Population[edit | edit source]
Individuals who have had an ankle fracture.
Method of Use[edit | edit source]
OMAS uses a summated rating scale format and consists of 9 questions:
- pain (0 to 25)
- stiffness (0 to 10)
- swelling (0 to 10)
- stair climbing (0 to 10)
- running (0 to 5)
- jumping (0 to 5)
- squatting (0 to 5)
- use of supports (0 to 10)
- work/activity level (0to20)
The highest possible score is 100 and higher scores indicate better outcomes
Evidence[edit | edit source]
Reliability[edit | edit source]
In a Swedish study of OMAS among people surgically treated after an ankle fracture, the following conclusions were made:[2]
- Test-retest reliability = very high
- rho = 0.95
- ICC = 0.94
- Standard error of measure = Low
- SEM = 4.4 points
- SEM% = 5.8%
- Internal consistency = 0.76
Validity[edit | edit source]
Concurrent validity using Foot and Ankle Outcome Score (FAOS) and Global Self-Rating Function (GSRF) = high[2]
- correlation coefficients versus the five subscales of FAOS ranged from rho = 0.80 to 0.86.
- There were significant differences between GSRF groups “good”, “fair” and “poor” (p < 0.001) at both the six-month and the 12-month follow-up.
Responsiveness[edit | edit source]
The effect size between results from 6-month and 12-month follow-up = 0.4. This finding is considered as medium, suggesting that there was a noticeable difference in ankle function between the two time-points, but it was not extremely large.[2]
