“…The lower normal limit of the reduced pressure (FSP(A)) after finger cooling has been used as a criterion56 and has been compared with a hand cooling test in a single study. 6 Nevertheless, Accepted 22 June 1987 only a reduction in pressure to zero (FSP(O) criterion) detects an attack of RP with complete arterial closure.27 The FSP(O) test and the hand cooling testthat is, the finger colour test-have never been compared in the same population.…”

Four objective tests to evaluate Raynaud's phenomena (RP) in workers exposed to handarm vibrations were applied on 23 exposed men with RP (vibration induced white finger 18, primary Raynaud's phenomenon 5), 56 exposed men without RP, and 15 male controls. Finger systolic blood pressure was measured by a cuff and strain gauge technique after combined body cooling and finger cooling during five minute ischaemia to 300, 15°, and 6°C. An attack of RP was detected as a zero pressure, FSP(0) test, whereas a pressure, reduced to a value below the normal 95% confidence limit at 60C, was regarded as an abnormal response, FSP(A) test. A hand cooling, preceded by 30 minute body precooling, was performed in water at 10°C during five minute ischaemia. The finger colours after hand cooling were evaluated by a directly visual inspection, FCV test, and by a blind assessment of slides of the photographed hand, FCS test. A medical interview was used as a method of reference. The sensitivity did not differ significantly between FSP(O) (74%), FCS (61%), and FCV (57%) (p > 0-10). FSP(A) had a significantly higher sensitivity (96%) and lower specificity (64%) than those of FCV and FCS (p < 0 0005) and of FSP (0) A medical interview is generally accepted for diagnosing Raynaud's phenomena (RP) in workers exposed to hand-arm vibrations. From the clinical and medicolegal points of view, however, objective diagnostic tests are needed. The main problem in objective diagnosis of RP is related to the episodic nature of vascular spasms that must be provoked under test conditions. The nosographic sensitivity of the classic cooling test, in which the finger colours are evaluated by visual inspection after hand cooling, varies considerably in workers exposed to vibration.'

“…For assessment of digital vascular function by measuring FSBP in subjects exposed to hand-arm vibration, the ISO has standardized the test conditions for optimal provocation, which includes reference measurement at 30°C followed by finger cooling for a period of 5 min at 15 and 10°C without or with additional body cooling 38) . Reported sensitivities and specificities of the local cooling tests with FSBP measurement by plethysmography from different studies are presented in Table 3 6, 25, 39, [43][44][45][46][47][48][49][50][51][52] . Among those reports, a good number of studies demonstrated the sensitivity and specificity of the local cooling test with FSBP measurement to be more than 80%, without additional body cooling, indicating satisfactory diagnostic performance of this method.…”

This study was undertaken to review the diagnostic ability of different quantification methods in the assessment of vibration-induced white finger (VWF), the typical clinical manifestation of vascular injuries in Hand-arm Vibration Syndrome (HAVS). Methods: A literature search of original and major review articles related to the quantification techniques for diagnosing vascular injuries in HAVS was performed. Relevant data from the publications were extracted and included in this study for reporting and discussion. Results: Few studies were available to substantiate the diagnostic techniques using the nail press test and nailfold capillaroscopy. Also, few studies were found to conclusively demonstrate the diagnostic ability using thermometry and thermography incorporated with cold provocation. Some recent reports raised the question regarding the diagnostic ability of finger plethysmography; but by virtue of its comparable assessment parameters and better diagnostic performance, plethysmography appears to be a suitable diagnostic method. In noninvasive quantification of vascular injuries, diagnostic techniques like laser Doppler perfusion imaging and nailfold capillaroscopy require further evaluation in future studies. Conclusions: For a reliable objective diagnosis of VWF at present, quantification of vascular responses using a test battery including established methods like thermometry or thermography and strain gauge plethysmography appears to be useful.
