Laser Therapy On Foot Ulcers 2020
Laser therapy has been shown in studies to help all types of foot pain, even neuropathies!
In this post, we are listing some of the studies concluding the benefits gained from using light therapy treatment on foot ulcers. The studies, as follows:
Laser Accelerates Healing in Indolent Diabetic Foot Ulcers
PMID: 31679662 DOI: 10.1053/j.jfas.2019.07.023
The objective of the study was to evaluate the effect of the erbium:yttrium aluminum garnet (YAG) laser on diabetic foot ulcers (DFUs) that had not responded to standard care. We retrospectively evaluated 22 nonhealing DFUs that received at least 4 weeks of standard wound care, demonstrated poor healing response, and subsequently were treated with an erbium:YAG laser. We measured the percent wound area reduction (PWAR) for the 4 weeks before initiating laser therapy and the PWAR for 4 weeks after the initiation of laser therapy.
Erbium:YAG laser treatment consisted of 2 components: debridement and resurfacing. The laser settings were the same for all treatments. We used the paired t test to compare pretreatment with posttreatment wound area reduction. During the 4-week period before the initiation of laser therapy, the average PWAR was -33.6%. Four weeks after initiating treatment with the erbium:YAG laser, the average PWAR was 63.4% (p = .002) and 72.7% of wounds had ≥50% PWAR. By 12 weeks, 50% of wounds had healed.
Conclusion: Laser therapy accelerated DFU healing in a cohort of patients with ulcers that had been unresponsive to standard of care therapy.

Jul-Aug 2016;50(4):628-634. doi: 10.1590/S0080-623420160000500013.
Objective: To evaluate the effects of low-level laser therapy isolated and associated with Calendula officinalis oil in treating diabetic foot ulcers.
Method: An experimental, randomized, controlled, prospective, interventional clinical case study using a quantitative approach. The sample consisted of 32 diabetic patients of both genders. Participants were randomly divided into four groups. Doppler Ultrasound evaluation of the Ankle-Brachial Index, brief pain inventory and analog pain scale were performed at baseline and after 30 days.
Results: Reduced pain was observed in the Low-level laser therapy and Low-level laser therapy associated with Essential Fatty Acids groups (p<0.01). Regarding the Ankle-Brachial Index and Doppler Ultrasound, all groups remained stable. By analyzing lesion area reduction, Low-level laser therapy associated with Essential fatty acids group showed a significance of p=0.0032, and the Low-level laser therapy group showed p=0.0428.
Conclusion: Low-level laser therapy, performed alone or associated with the Calendula officinalis oil was effective in relieving pain and accelerating the tissue repair process of diabetic foot.
Efficacy of high intensity laser therapy in the management of foot ulcers
PMID: 30349176 PMCID: PMC6181666 DOI: 10.1589/jpts.30.1341
[Purpose] The aim of this systematic review was to assess the efficacy of high intensity laser therapy (HILT) on wound surface area in patients with foot ulcers. [Methods] Four databases including PubMed, MEDLINE, the Cochrane library, and the Physiotherapy Evidence Database (PEDro) were searched up to the end of April 2018 to identify relevant studies. Studies were included if they met the following criteria: randomised controlled trial (RCT), assessed the efficacy of HILT in patients with foot ulcers, evaluated wound surface area, and written in English language with available full text.
The PEDro scale was used to evaluate the quality of studies. [Results] A total of three RCTs met the inclusion criteria, with two studies of the efficacy of HILT in adult patients with diabetic foot ulcers and one in spina bifida children with neuropathic foot ulcers. According to the PEDro scale assessment, all three studies were rated as a fair quality. All studies found that HILT provided significantly better outcomes compared to sham laser or standard medical therapy.
Conclusion: This systematic review suggests that laser therapy is an effective modality for wound healing in patients with foot ulcers.
Low-level laser therapy as an adjunct to conventional therapy in the treatment of diabetic foot ulcers
PMID: 27896528 DOI: 10.1007/s10103-016-2109-2
Foot ulcers are serious complications of diabetes mellitus (DM) and are known to be resistant to conventional treatment. This study was conducted to evaluate the efficacy of low-level laser therapy (LLLT) for the treatment of diabetic foot ulcers in a tertiary care centre (Department of Surgery, Mahatma Gandhi Memorial Medical College and Maharaja Yashwantrao Hospital, A.B. Road, Indore). A total of 30 patients with type 2 DM having Meggitt-Wagner grade I foot ulcers of more than 6 weeks duration with negative culture were studied. Patients were randomized into two groups of 15 each.
Patients in study group received LLLT (660 ± 20 nm, 3 J/cm2) along with conventional therapy and those in control group were treated with conventional therapy alone. The primary outcome measure was the absolute and relative wound size reduction at 2 weeks compared to the baseline parameter. Percentage ulcer area reduction was 37 ± 9% in the LLLT group and 15 ± 5.4% in the control group (p < 0.001). For ∼75% of wounds of the treatment group, wound area reduction of 30-50% was observed. In contrast, for the control group, ∼80% of wounds showed a wound area reduction of <20% on day 15. Further, the wounds with initial wound area 1000-2000 mm2 seems to have better final outcome than the groups with larger areas. The treated groups showed higher amount of granulation than the control group.
Conclusion: The results suggest that Low Level Laser Therapy is beneficial as an adjunct to conventional therapy in the treatment of diabetic foot ulcers.
Effects of the Low-Level Laser Therapy (LLLT) in the process of healing diabetic foot ulcers
PMID: 26735058 DOI: 10.1590/S0102-865020150120000010
Purpose: To evaluate the effects of the low-level laser therapy applying Laser on the tissue repair in ulcer carriers due to diabetes.
Methods: Sixteen type II diabetic patients, ulcer carriers in the lower limbs, participated in the research from which eight were in the control group and eight were submitted to the low-level laser therapy with a pulsed wave form, visible ray, wave length of 632.8 nm, 30 mW peak power, (Laser – HTM). The application time was of 80 (4J/cm2) seconds. The application was punctual without contact (approximately 1mm of distance), the pen being held in a perpendicular position related to the wound, in equidistant points. There were 12 appointments, of which three were done weekly in alternated days. Photograph records and an application of the brief inventory of pain were done before and after 30 days of follow-up.
Results: There was a significant decrease in the size of the wound when compared to the control group (p<0.05). The pain was also reported as having an intense improvement in the treated group.
Conclusion: The low-level laser treatment seems to be an efficient method, viable, painless and of low costs concerning the tissue repair ulcers in a diabetic foot.
