Debridement is an essential component of wound care as the presence of devitalised tissue can impede the healing process. Larval therapy has been used for the debridement of wounds for several hundred years. A plethora of literature is available on larval therapy, but many authors acknowledge the paucity of large-scale clinical trials supporting its effectiveness. While the exact mechanism of larval therapy remains unknown, it encompasses three processes: debridement, disinfection and promotion of healing. This literature review discusses the applications, benefits and disadvantages of larval therapy as well as the processes involved. The literature reviewed suggests that further comprehensive research into the mechanisms involved in larval therapy is required to ensure that it may be used to best medical advantage.
It would seem that LILT provides no advantages in the management of minor postoperative wounds over current practice. Despite no apparent benefit of infrared laser at this dosage in the management of acute stage wounds, further research is required to determine its potential efficacy in the management of other wound types.
These findings provide only limited evidence for the use of this modality as an adjunctive therapy with current nursing intervention. Further group studies are indicated to investigate the apparent delayed effect reported here for various etiologies of ulceration.
The current study compared the effectiveness of the graduated tuning fork (128 Hz) and the neurothesiometer in assessing vibration sensation perception in patients presenting with type II diabetes mellitus. A quota sample of patients (n = 21; age range 43-73 years) were assessed using the neurothesiometer and tuning fork by two investigators at five sites on both feet. There was a positive correlation between the results for the two methods of assessment for both investigators, and also between the results for both tools at three individual sites. Overall, there was 66.2% agreement between the results obtained from the two investigators using the tuning fork at each site; however, Kappa values only reached statistical significance at one site, indicating variability between the results from the two tools. This study suggests that assessment of vibration sensation with the tuning fork may be unreliable. These preliminary findings are based on a small sample size; thus further research is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
