From: A systematic review of objective burn scar measurements
Device | Company | Parameter | Intra-rater Reliability | Inter-rater reliability | Correlation with clinical score | Cost | Portability | References |
---|---|---|---|---|---|---|---|---|
Cutometer | Courage + Khazaka | Viscoelastic parameters | Ranges from unacceptable to good (0.12–0.76)*; poor in severe firm scars | Ranges from unacceptable to good (0.11–0.93)*, poor in severe firm scars | Low to moderate, but significant (Spearman’s r = −0.29 to −0.53). Rennekampf et al. could not find any significant correlation between objective viscoelastic measurements and the subjective pliability assessment of the VSS. | £5000–£10,000 (with hub) | Yes | Nedelec et al. 2008 [30, 106], Draaijers et al. 2004 [147], Rennekampf et al. 2006 [142]. |
Dermalab Elasticity probe | Cortex | Viscoelastic parameters | ICC = 0.90–0.93; limited ability to measure rigid scars | ICC = 0.86–0.93; limited ability to measure rigid scars | No data | £5000–£10,000 (with hub) | Yes | Gankande et al. 2014 [6]. |
Tonometer | Flinders Medical Centre Biomedical Engineering | Viscoelastic parameters | ICC = 0.90–0.94 | ICC = 0.948 | Negative correlation between VSS pliability scores and tonometer readings: −0.457 and −0.442 respectively for 3 and 6 second readings. | No longer commercially available | Yes | |
Durometer | Rex Gauge company | Viscoelastic parameters | No data | No data for scars but ICC = 0.82–0.92 for sclerodermal skin | Good correlation with modified Rodnan skin score (0.70) for sclerodermal skin | <£1000 | Yes | Merkel et al. 2008 [160]. |
Dermal Torque meter | Dias-tron | Viscoelastic parameters | No data | No data | No data | N/a | Yes | Boyce et al. 2000 [165]. |
Adheremeter | Fondazione Salvatore Maugeri | Viscoelastic parameters | Good (0.96) | Good (0.87–0.99) | Moderate correlation with VSS and Pliability subscale of VSS (rs = −0.58 to −0.66) | Free | Yes | Ferriero et al. 2010 [169]. |
Reviscometer | Courage + Khazaka | Resonance running time | Good (>0.86) | No data | No data | £10,000–15,000 (with hub) | Yes | Verhaegen et al. 2010 [168]. |
Vesmeter | Wave Cyber Co. Ltd. | No data | No data | No data | No data | N/a | Yes | Niyaz et al. 2012 [246]. |
Shear Velocity Device | N/a | Shear wave propagation velocity | No data for ICC. (CV for scars is ±4.8 %) | No data | No data | Not commercially available | Yes | McHugh et al. 1997 [166]. |
