Question

10. Which of the following MSDs may first manifest as night-time numbness in the hands? (a.) Carpal tunnel syndrome b. Tendonitis syndrome c. Thoracic outlet syndrome d. Tenosynovitis syndrome

Answer 1

a. Carpal tunnel syndrome

Step-by-step explanation:

Symptoms of carpal tunnel syndrome tend to be worse at night because the tissue fluid in the arms becomes redistributed without an active muscle pump. The skeletal-muscle pump is a collection of skeletal muscles that help the heart circulate blood. When an individual is not active during the night, an increase in fluid causes an increase in carpal tunnel pressure, which makes symptoms worse.
