A systematic review of objective burn scar measurements

Table 2 Comparison of laser devices in terms of parameter measured, reliability, correlation with clinical score and cost

Device	Company	Parameter	Intra-rater reliability	Inter-rater reliability	Correlation with clinical score	Cost	Portability	References
Laser Doppler Flowmeter	Moor	Blood flow	No data	No data	LDF showed significant difference in blood flow within hypertrophic and keloid scars and normal skin (2.6–2.8-fold higher).	>£30,000	Poor	Clark et al. 1996 [56], Timar-Banu et al. 2001 [53].
Laser Doppler Imaging	Lisca, Moor	Blood flow (red and near infrared wavelengths)	No data	No data	Correlations with clinically assessed grades (VSS) of pigment, vascularity, pliability, and height ranged from r ² = 0.63 to 0.95.	>£30,000	Poor	Stewart et al. 2005 [60] Bray et al. 2003 [49].
Laser Speckle Perfusion Imaging	Moor	Blood flow	No data	No data	Correlations with clinically assessed grades (VSS) of pigment, vascularity, pliability, and height ranged from r ² = 0.73 to 0.94.	>£30,000	Poor	Stewart et al. 2005 [60]
