Background:
Previous research on functional impairments due to vascular effects in workers with hand-arm vibration syndrome (HAVS) has focused on the upper extremities with little attention to the lower extremities.
Aims:
To examine the severity and factors associated with cold intolerance and sensitivity in the hands and feet of workers with HAVS.
Methods:
A survey and retrospective chart review were used to collect demographics, work conditions and disease characteristics on workers undergoing HAVS assessments. Data also included workers' scores on the Cold Intolerance Symptom Severity (CISS) questionnaire, which was adapted to evaluate the upper and lower extremities separately. Associations between upper and lower extremity scores were explored using Spearman correlations and Wilcoxon signed rank tests, and regression models were used to evaluate whether variables of interest predicted CISS total scores.
Results:
Participants (N = 93; 55% response rate) worked primarily in mining and construction, were exclusively male, and had a mean age of 48 years. Cold intolerance and sensitivity were commonly reported in the feet and correlated with hand symptoms, but most CISS individual questions and total scores were significantly higher for the hands (versus feet). Regression models indicated that QuickDASH and Stockholm vascular scale scores significantly predicted CISS total scores for the hands, while exposure to foot vibration, plethysmography severity scores of the feet and QuickDASH scores significantly predicted CISS total scores for the feet.
Conclusions:
Clinicians should assess and treat cold intolerance and sensitivity in both the hands and feet of workers with HAVS to improve workers' daily functioning.

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...

Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
