Assessment of work-related risks factors for carpal tunnel syndrome
1Department of Occupational Medicine, Division of Community Medicine and Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer Sheva, Israel.
Background:
The association of carpal tunnel syndrome with occupational risk factors is well established. However, in clinical practice these factors are only rarely considered and evaluated. Managing these risk factors could prevent the occurrence of future cases and alleviate treatment of the afflicted individuals.
Objectives:
To estimate the role of occupational risk factors in a large group of patients diagnosed by electrophysiological studies as suffering from CTS.
Methods:
A group of 396 subjects (204 women, 165 men) who were tested in one laboratory by electrophysiological studies were further evaluated (by questionnaire) to determine the possible role of occupational and other risk factors in the etiology of their syndrome.
Results:
Persons employed in high force--low repetitive or low force--high repetitive jobs, harbor an extra risk for developing CTS as compared with controls, OR = 3.21 (95% C1 = 1.5-6.9) and OR = 4.72 (95% C1 = 1.8-12.5), respectively. These jobs include typists/secretaries, nursing personnel, production workers and housewives.
Conclusion:
Evaluation of a general group of examinees referred for electrophysiological studies on sympathology compatible with CTS may show that occupational risk factors play a substantial role in the development of symptoms. By increasing the awareness of clinicians and the public to these risk factors, appropriate preventive measures can be introduced and the burden of the disease reduced.

The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

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...
