Our objective was to summarize and quantify the effects of a noncontact
low-frequency ultrasound (NLFU) therapy on healing of chronic wounds. We
performed a meta-analysis of eight published studies reporting effects of NLFU on
wound size and healing rate of chronic wounds in 444 NLFU-treated patients. A
search of the PubMed database was conducted in January 2010 and updated in
October 2010. We used random-effects linear regression models to estimate the
proportional reductions in wound area and volume and the proportion of wounds
healed from baseline to last follow-up. In four studies (N=188) reporting change
in wound area from baseline, NLFU was associated with 85.2% area reduction (95%
CI 64.7%-97.6%) over a mean 7 weeks. In four studies (N=278) reporting reduction
in wound volume, NLFU was associated with 79.7% volume reduction (95% CI
46.1%-98.8%) over a mean 12 weeks. In seven studies (N=429) reporting proportion
of wounds healing by study end (mean time to healing 8.2 weeks; median 6.8
weeks), meta-analyzed healing rates over time suggest 32.7% of wounds healed on
average by 6 weeks (95% CI 23.3%-42.1%) and 41.7% by 12 weeks. NLFU for treatment
of chronic wounds was associated with consistent and substantial wound size
reductions, as well as favorable rates of healing.
