Accuracy and reliability of the Mayo Elbow Performance Score

Area of Science:

• Orthopedic Surgery
• Rehabilitation Medicine
• Clinical Outcomes Assessment

Background:

• Elbow dysfunction impacts patient quality of life.
• Reliable outcome measures are crucial for evaluating nonsurgical elbow treatments.
• The Mayo Elbow Performance Score (MEPS) is a potential tool for assessing elbow function.

Purpose of the Study:

• To evaluate the test-retest reliability of the Mayo Elbow Performance Score (MEPS).
• To compare the MEPS with a validated outcomes instrument, the American Shoulder and Elbow Surgeons (ASES) score.

Main Methods:

• 42 patients with elbow dysfunction completed the MEPS twice, 2-3 weeks apart.
• Patients also completed the ASES elbow assessment during the second visit.
• Pearson correlation coefficients were used to calculate reliability and accuracy.

Main Results:

• MEPS scores showed strong agreement between the two time points (Pearson coefficient = 0.82).
• MEPS scores demonstrated strong agreement when compared with ASES scores (Pearson coefficient = 0.83).
• Both instruments indicated similar accuracy, with equivalent confidence intervals and standard deviations.

Conclusions:

• The MEPS is a reliable instrument for assessing elbow function in clinical research.
• The MEPS demonstrates strong reliability and accuracy when compared to the validated ASES score.
• The MEPS is suitable for evaluating nonsurgical treatments for elbow conditions.
