Objective:
Evaluate the validity of two self-report symptoms surveys with two disorder classification protocols.
Participants:
100 graduate students at a private school in the Southwest United States.
Methods:
Study participants completed two self-report upper extremity musculoskeletal symptoms surveys: a nine item 10 cm Visual Analogue Scale (VAS) and a nine item Likert categorical scale anchored from "None" to "Very severe". Clinical examinations were administered using two musculoskeletal disorder classification protocols.
Results:
For the nine body regions, concordance between the two self-report symptoms scales ranged from 0.49-0.75. Overall there was greater than 80% agreement for the two disorder classification protocols. Using either symptom survey with either disorder classification protocol provided high sensitivities and specificities (Youden's J ≥ 0.70). Three of possible six symptom survey/classification protocol pairings provided high sensitivities and specificities across all disorder groups.
Conclusion:
In this graduate student sample, none of the self-report symptom survey-classification protocol pairings was demonstratively more useful than any other pairing for studies of musculoskeletal disorders among computer users.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
