“…The diagnostic value of finger thermometry and PPG in the assessment of HAVS was discussed by Bogadi-Sare and Zavalić [ 24 ]. SWS and PPG scores were weakly correlated, and the authors suggested that they measure two different aspects of the vascular response [ 3 ].…”

“…Cold provocation finger thermometry and plethysmography, such as strain gauge plethysmography and photoplethysmography (PPG), are commonly used laboratory tests for VWF. PPG [ 3–6 ] is a non-invasive optical technique that uses low-intensity light to detect blood volume changes in the microvascular tissue bed [ 7 ].…”

“…Little is known about the influence of comorbidities on the course of HAVS [ 13 ]. SWS and PPG scores are weakly correlated [ 3 , 4 ], and some have speculated whether they may measure two different aspects of the vascular response [ 3 ]. Whether the SWS is fit for this purpose has been discussed previously [ 14–16 ].…”

BackgroundVibration-induced white finger (VWF) is often assessed using the Stockholm Workshop Scale (SWS) and cold challenge plethysmography. However, long-term longitudinal studies using both methods are scarce.AimsTo study the long-term course and prognostic factors of VWF assessed with the SWS and photoplethysmography (PPG), and to examine the effects of lifestyle on PPG score, regardless of VWF status.MethodsForty male construction workers were examined with a test battery and clinical examination in 1994 and 2016/17.ResultsAt baseline, the sample comprised 27 workers with, and 13 without, symptoms of hand-arm vibration syndrome (HAVS). Thirty-five workers reported vibration exposure during follow-up. The mean age of the workers was 60 years (45–78) at follow-up. The paired t-test showed that PPG scores deteriorated from 1994 to 2017 in the 27 workers with HAVS in 1994 (mean difference 2.7 min, 95% confidence interval (CI) 0.2–5.2). However, there was no statistically significant change in SWS scores in these workers over time. Smoking and age were associated with PPG score deterioration. Vibration exposure during follow-up predicted SWS score deterioration: 1000 h of exposure predicted a deterioration stage of 0.09 (95% CI 0.03–0.16). Analysis of all 40 workers showed that 2017 PPG scores were associated with positive serum cotinine and self-reported smoking during follow-up.ConclusionsWhereas age and smoking predicted a PPG deterioration, continued vibration exposure predicted worsening of white finger symptoms. The association of PPG score and smoking should be considered in diagnostic and prognostic factor evaluations.

“…[10] In traumatology, impedance plethysmography has been used to assess changes in blood flow following the application of low temperature for extremity injuries. [17,18] In occupational medicine, impedance plethysmography has been used in a number of studies regarding the influence of exposure to topical vibration on the peripheral blood flow in limbs [19][20][21][22]. It has also been used to examine the changes of the peripheral blood flow in response to topical cooling of limbs [23,24].…”

The thermal environment in the workplace is an important factor which affects workers' health. During 2011 in Poland, 14,781 workers were exposed to a cold working environment, i.e., 3.8% of persons employed in hazardous work conditions. The aim of this study was to determine the cardiovascular response to continuous (4°C for 60 min) and intermittent (10 min at 4°C and 10 min at room temperature alternately) exposure to the cold in 30 healthy men aged 20-27 years. Peripheral blood flow was assessed with impedance plethysmography. Heart rate and arterial blood pressure were monitored with the Holter system. Having assessed the results, it is difficult to say which kind of exposure has a more severe impact on the cardiovascular system. Longer observation and a more detailed analysis would be necessary (e.g., Doppler echocardiography).

“…The cold provocation test is a valuable objective tool for monitoring of vibration induced neurovascular disturbances with dose-effect relation between the cold-provoked vasomotor response and the cumulative vibration exposure. 12 Thermistor thermometry of the limbs, combined with distal Doppler sonography and cold provocation test correlate signifi cantly with each other and with the stage of vibration disease 13 , making their application for objective assessment of autonomic neurovascular injuries in vibration disease appropriate. 14 С. Aström et al determine signifi cant correlation between whole-body vibrations exposure and the increased risk for musculoskeletal alterations in the neck, the shoulders and the wrists similar to those caused by local vibration impact as well as dependence on the cumulative time of exposure.…”
