WRIST

Modified Mayo Wrist Score

The score assesses four domains: Pain, Function, Range of Motion and Grip Strength. Each of them is scored out of 25, for a maximum possible total score of 100. A score of 91 and above is considered ‘Excellent’ and one below 65 is considered ‘Poor’. The score is a modification of the earlier Green and O’Brien score, but the reliability and validity of this score has not been studied.

Munich Wrist Questionnaire

The MWQ consists of 16 items in three domains – Pain (5 items), Work & ADL (7 items), Function (4 items). Scoring is performed out of 250, which is then converted to a scale of 100%. The questionnaire is designed to be filled by the patients themselves, including range of motion and strength items.

Patient Rated Wrist Evaluation

PRWE is a 15-item questionnaire with two subscales: Pain (5 items) and Function (10 items). Each item is scored from 0 to 10 by the patient, with higher scores representing higher disability. The total score is out of 100, as given below

Pain subscale: total score of 5 items (out of maximum 50)
Function subscale: [total score of 10 items (maximum 100)] ÷ 2
Total score = Pain score + Function score (out of 100)
The minimal clinically important difference of the PRWE is estimated as 14 points [95% confidence interval 8 – 20].
