To systematically assess published reports on the efficacy of electrophysical therapy in the treatment of diabetic foot ulcers, including electrical stimulation, low-level laser therapy, therapeutic ultrasound and electromagnetic therapy. Databases searched included MEDLINE, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials (CENTRAL) from 1966 to 2011. Studies reviewed included only randomised controlled trials (RCTs) on treatment with electrophysical modalities compared with sham, conventional treatment or other electrophysical modalities. ⋯ The pooled estimate of the number of healed ulcers of the three studies on electrical stimulation compared to the control or sham electrical stimulation showed statistical significance [mean difference of 2·8 (95% CI = 1·5-5·5, P = 0·002] in favour of electrical stimulation. The results indicated potential benefit of using electrophysical therapy for managing diabetic foot ulcers. However, due to the small number of trials ever conducted, the possibility of any harmful effects cannot be ruled out, and high-quality trials with larger sample sizes are warranted.

Randomized Controlled Trial
Clinical evaluation of gauze-based negative pressure wound therapy in challenging wounds.
The aim of this randomised clinical study was to evaluate the effectiveness and safety of gauze-based negative pressure wound therapy (NPWT) in patients with challenging wounds. A total of 50 consecutive patients who had wound drainage for more than 5 days, required open wound management and had existence of culture positive infection were included the study. In this study, gauze-based NPWT was compared with conventional dressing therapy in the treatment of patients with difficult-to-heal wounds. ⋯ The patients treated with antibacterial gauze-based NPWT had a significantly reduced recurrence (2 wounds versus 14 wounds, P = 0·001), and increased number of the culture-negative cases (22 wounds versus 16 wounds, P < 0·047) in a follow-up period of 12 months. There was a statistically significant difference between two groups in all measurements. As a result, we can say that the gauze-based NPWT is a safe and effective method in the treatment of challenging infective wounds when compared with conventional wound management.
