1. The type of activity patterns in the neck/shoulders muscles associated with computer work causes a selective activation of low-threshold motor units with type II muscle fibers.

A. True B. False

2. The frequency of gaps in trapezius muscle activity, that is, periods with complete motor unit relaxation, seems to be associated with neck/shoulder pain.

A. True B. False

3. A moderate reduction in pain and muscle tenderness can be obtained in response to as little as _____ of daily neck/shoulder resistance training performed as a single set to failure.

A. 1 minute B. 2 minutes C. 3 minutes D. 4 minutes

4. A possible explanation for the relationship between the length of the EMG gap and the level of pain intensity can be that longer EMG gaps, compared to shorter EMG gaps, cause a higher average work strain.

A. True B. False

5. Women suffering from chronic neck muscle pain experience increased levels of both lactate and pyruvate in the interstitium as a result of low-force repetitive work. This has been suggested to reflect:

A. Increased anaerobic metabolism B. Reduced blood flow C. Insufficient capillarization of the muscle fibers D. All of the above

6. In general, the findings of the present study suggest that the splenius muscle, compared with trapezius, is the primary site for pain sensation in the neck/shoulder muscles due to the fact that EMG alterations primarily appear in the splenius.

A. True B. False

7. The acute response to a single session of resistance training appeared to generate a favorable muscle activity pattern.

A. True B. False

8. The longitudinal changes:

A. Were beneficial. B. Had longer periods of complete muscular relaxation and reduced pain. C. Had more frequent periods of complete muscular relaxation and reduced pain. D. All of the above.
