LASER IS MORE EFFECTIVE AT HEALING THAN ULTRASOUND!

Laser therapy vs ultrasound Laser therapy more effective In this study, animals were treated with either low level laser therapy (LLLT) or Low Intensity Pulsed Ultrasound (US). Each animal received six sessions for damaged muscle tissue. Laser therapy vs ultrasound The researchers concluded that US helped soft tissue injuries less effectively than low level laser therapy (LLLT). This study revealed that both LLLT and US therapies have positive effects on muscle metabolism after an injury, but LLLT produced a better response.

Comparative effects of low-intensity pulsed ultrasound and low-level laser therapy on injured skeletal muscle. Photomed Laser Surg. 2011 Jan;29(1):5-10. PMID: 21166589. Abstract OBJECTIVE: The main purpose of this study was to compare the effects of low-intensity pulsed ultrasound (US) and low-level laser therapy (LLLT) on injured skeletal muscle after cryolesion by means of histopathological analysis and immunohistochemistry for cyclo-oxygenase-2 (COX-2). BACKGROUND AND METHODS: Thirty-five male Wistar rats were randomly […]

USING LASER THERAPY TO TREAT CHRONIC PAIN

Laser therapy and chronic pain Laser therapy for pain syndrome The aim of the study was to evaluate and compare the effects of low level laser therapy (LLLT) with interferential current (IF) in the treatment of CRPS (sometimes called RSD). CRPS, Complex Regional Pain Syndrome, is a severe and chronic pain condition that has few successful medical interventions. In this controlled study 45 patients with unilateral CRPS were treated with laser therapy. Group A was treated with laser therapy and group B was treated with IF. There was a statistically significant improvement with both groups, but the decrease in pain was significantly higher in the laser therapy group. This study shows three important findings: laser therapy is effective treating serious chronic pain conditions; laser therapy and Interferential both have benefit; laser therapy is superior to Interferential with chronic pain. This study supports the work of Dr. Basford from Mayo Clinic showing successful treatment of CRPS with laser therapy. It also supports prior studies showing that laser therapy is generally superior to electrical stimulation, with the caveat that some studies show laser plus electrical stimulation has a synergistic effect.

TREATING ORAL MUCOSITIS WITH LASER THERAPY

Laser therapy and oral mucositis Laser therapy for painful side effect of chemotherapy Oral Mucositis (OM) is a very painful side effect of chemotherapy. Patients who have received high doses of chemotherapy, either alone or in combination with total body radiation, often cite OM as the most debilitating side effect. Prior studies have shown that laser therapy can treat OM and provide significant relief and speed healing. However, no study has looked at trying to prevent OM before it begins. The researchers studied 42 patients who underwent stem cell transplant with radiation and chemotherapy. In the  laser therapy group, 57.1% of patients had no pain when they received  laser therapy prior to treatment, whereas in the control group, only 4.8% of patients were free of pain! The results demonstrate that laser therapy can not only heal this serious problem, it can even prevent it!

LASER AND CORTISONE TOGETHER?

Laser therapy and cortisone Laser therapy synergistic effect with cortisone At one time it was thought that laser therapy was ineffective when used with cortisone. Newer studies are showing that laser therapy actually may have a synergistic effect with cortisone. This animal study aimed to assess the effect of laser therapy associated with and without dexamethasone on inflammation and wound healing in surgical wounds. The results showed that laser therapy and dexamethasone acted in a similar pattern to reduce acute inflammation! Collagen synthesis and tissue healing were more intense in the laser group and laser therapy was effective in reducing swelling and accelerated repair, even in the presence of dexamethasone.

LASER TREATMENT FOR TEMPOROMANDIBULAR DISORDER

Laser therapy and temporomandibular disorder (TMDs) Laser therapy for masseter muscle In dentistry today, LLLT is used on patients with temporomandibular disorders (TMDs), mainly for radiating pain in the masticatory muscles. This study evaluated how the number of laser applications can affect the masseter muscle. Thirty animals were randomly distributed into groups according to the number of laser applications they would receive. It was found that six applications of laser had a positive effect on the muscle physiology, but there was little difference between 6 and 10 applications. The SDH enzyme activity revealed that the number of laser applications increases the metabolic pattern of the muscle fibers. The authors suggest that further studies should be done to confirm if six applications are enough to produce the same clinical effects as more treatments. This is an important study because it supplies data on the cost/benefit ratio of laser therapy. Insurance companies need to be informed of this type of information so they can improve reimbursement for laser therapy!
