Background/Aim. Complex regional pain syndrome type I (CRPS I) is characterized by continuous regional pain, disproportional according to duration and intensity and to the sort of trauma or other lesion it was caused by. The aim of the study was to evaluate and compare, by using thermovison, the effects of low level laser therapy and therapy with interferential current in treatment of CRPS I. Methods. The prospective randomized controlled clinical study included 45 patients with unilateral CRPS I, after a fracture of the distal end of the radius, of the tibia and/or the fibula, treated in the Clinical Centre in Nis from 2004 to 2007. The group A consisted of 20 patients treated by low level laser therapy and kinesy-therapy, while the patients in the group B (n = 25) were treated by interferential current and kinesy-therapy. The regions of interest were filmed by a thermovision camera on both sides, before and after the 20 therapeutic procedures had been applied. Afterwards, the quantitative analysis and the comparing of thermograms taken before and after the applied therapy were performed. Results. There was statistically significant decrease of the mean maximum temperature difference between the injured and the contralateral extremity after the therapy in comparison to the status before the therapy, with the patients of the group A (p < 0.001) as well as those of the group B (p < 0.001). The decrease was statistically significantly higher in the group A than in the group B (p < 0.05). Conclusions. By the use of the infrared thermovision we showed that in the treatment of CRPS I both physical medicine methods were effective, but the effectiveness of laser therapy was statistically significantly higher compared to that of the interferential current therapy.

Background: Diabetic wound is a major socioeconomic debilitating problem in this society. Various treatment options are available but still it requires better treatment option. In diabetes mellitus the oxygenation to the tissues is reduced. In this study effects of low level laser therapy were compared with topical application of Streptococcus thermophilus on diabetic wounds that induces formation of new blood vessel and free radical scavenging system, a comparative study to get better treatment option for diabetic wounds.Methods: 18 male rats were selected and divided randomly into three groups. Diabetes was induced in all the rats by using the Alloxan monohydrate at a dose of 120mg/kg of the body weight. Group A was treated with normal saline, group B was treated with low level laser therapy and group C was treated with Streptococcus thermophilus topically. Skin tissues were collected on day three and seven, slides were prepared for microscopic examination to observe the new blood vessels formation.Results: Mean number of new blood vessel formation was observed in group B compared with group A and C. Significant vasculogenesis was seen in group B when treated with Low level laser therapy.Conclusions: In the group of low level laser therapy new blood vessel formation was seen with better wound healing. It means LLLT provides better oxygenation to the tissues by generation of new blood vessels compared with Streptococcus thermophilus and normal saline.

Abstract Objective Postnatal scanty milk secretion is a common complaint. Some physical and medical interventions were advocated to help milk production. These interventions should be effective and safe for the mother and the infant. This study aimed to compare the effects of low-level laser therapy and electroacupuncture on postnatal scanty milk secretion. Study Design A randomized controlled study conducted on 60 healthy primiparous mothers with insufficient lactation. They were randomly divided into three equal groups: group A (control), group B (those who received low-power He–Ne laser beam on both breasts), and group C (those who received faradic current stimulation at Spleen 6, Liver 3, and Small Intestine 1 acupuncture points on both sides). All participants received 10 mg Domperidone three times a day and were given advice about lactation, nutrition, and fluid intake. Evaluation was done before and after the treatment program. Results The mean serum prolactin, infant weight, and visual analog scale (VAS) score were significantly increased in the three groups posttreatment when compared with their corresponding levels pretreatment. Posttreatment serum prolactin was significantly elevated in group C more than the other two groups (p = 0.001 and 0.012, respectively). Also, it was significantly elevated in group B more than in group A (p = 0.001). The mean value of infant weight was significantly elevated in group C when compared with its corresponding values in both groups A (p = 0.001) and B (p = 0.029). The VAS score was significantly increased in both groups B and C when compared with group A (p = 0.001). Conclusion Electroacupuncture is more effective than low-level laser therapy in increasing postnatal scanty milk secretion. Clinical Trial Registration NCT03806062.

Objective: The study was designed to evaluate the efficacy of Cyriax physiotherapy versus Cyriaxand Low Level Laser Therapy to compare these techniques in reducing pain and improving gripstrength in patients with lateral epicondylitis. Methodology: The study population included 30patients of lateral epicondylitis (signs and symptoms present for more than 6 weeks) diagnosedin outpatient and indoor facilities of MM Hospital, Mullana. The subjects were selected bymeans of simple random sampling. After fulfilling the inclusion and exclusion criteria, thepatients were randomly allocated in two groups: Group A and Group B. Group A received cyriaxphysiotherapy alone whereas Group B patients were subjected to combined Cyriax and low levelLaser therapy. Baseline measurements of pain and grip strength were taken before treatmentand then at 3 weeks respectively. Results: Our findings showed that there was significantlyhigher improvement in pain and grip strength in Group B (patients receiving combination ofcyriax therapy with low dose laser therapy) as compared to Group A (p<0.05). Conclusion:Cyriax physiotherapy and low level laser therapy were effective in reducing pain and improvinggrip strength after the treatment sessions. But benefits of cyriax physiotherapy with low levellaser therapy in lateral epicondylitis patients are significantly higher as compared to cyriaxphysiotherapy alone over a three week period. Hence, cyriax with low level laser therapy isproved to be a better treatment. Bangladesh Journal of Medical Science Vol.20(2) 2021 p.356-360

Abstract Low level laser therapy (LLLT) is a form of phototherapy which may stimulate healing of injuries and lesions from exercise. Our objective was to determine effects of LLLT before or after exercise on equine serum concentrations of cortisol, lactate, and cytochrome P450 (CYP) inhibition. Twelve quarter horses were randomly assigned to one of three groups: (A) received no laser therapy, (B) received six minutes of laser therapy before exercise, and (C) received six minutes of laser therapy after exercise. Laser (635 nm) treatment was with a class II handheld low-level laser with constant wave modulation. Horses were exercised using a walker for 30 min five days a week for three weeks, and within 30 min after exercise blood was collected on day 7, 14, and 21; blood was collected on day 0 prior to exercise as a reference point. Serum was collected, frozen; and cortisol, lactate, and CYP inhibition were determined via validated assays. Data were analyzed by ANOVA with horse as the experimental unit; an interaction (P &lt; 0.05) between treatment group and day of study affected serum concentrations of cortisol, lactate, and CYP inhibition. For group B horses, cortisol concentrations decreased (P &lt; 0.001) from day 14 to day 21 (31 vs 20 ± 2.9 ng/mL). Serum lactate concentrations increased (P &lt; 0.0001) during the three weeks of training (2700, 2773, 3064, and 6061 ± 232 μM; respectively for day 0, 7, 14, and 21); whereas, inhibition of CYP decreased (P &lt; 0.01) from day 0 to day 21. Interaction of main effects on lactate can be explained by larger increases in lactate concentrations for horses treated with LLLT during the trial; conversely, CYP inhibition decreased for horses treated with LLLT after exercise. Our results suggest that LLLT may be useful in improving performance of equine athletes.

Spinal Cord Disorders

Background: The problem of protecting and maintaining health of workers in the microelectronics industry exposed to adverse occupational factors including tension and overstrain of the muscles of the upper extremities and visual strain, gains special relevance. Objective: Introduction of the developed and patented low-level laser therapy techniques to recover functions of vision and the musculoskeletal system impaired in the course of work. Materials and methods: The study involved 65 chip assemblers aged 26–41 years. Their eyes, the back of the hands, and the collar area were exposed to low-level laser radiation from the red region of the spectrum. All employees were examined by a neurologist and a surgeon and their working conditions were evaluated. The accommodation apparatus was tested using an AKA-01 type accommodation meter. Results: After five 10-minute sessions, we registered an increase in the volume of absolute accommodation during the observation period before and after the work shift by 28 % and 19 %, respectively. On subsequent days of observation, we noted an increase in the accommodation during 10 days, followed by a decrease by the 30th day of observation. Application of preventive techniques helped eliminate spinal cord disorders in all workers. Blood circulation in fingers increased by 66 % compared to the initial condition. Discussion: Low-level laser therapy improves blood supply, intensifies redox processes in the retina of the eye, skin cells, and blood vessels. Conclusions: Low-level laser radiation of the red region of the spectrum relieves the spasm of accommodation and normalizes the efficiency of the accommodation apparatus. Such laser therapy helps eliminate spinal cord disorders and improve blood circulation. Introduction of the developed techniques can prevent occupational diseases and reduce disability in patients.

Background: Radiotherapy (RT) has been the traditional treatment approach for head and neck carcinoma (HNC) and has resulted in both excellent control rates and function preservation. Oral mucositis (OM) is a frequent, severe toxicity in patients treated with RT and may lead to hospitalization and the treatment interruptions, which inuences quality of life. The aim of our study is to assess effect of low level laser therapy (LLLT) in the treatment of OM. Materials And Methods: A prospective single arm study was conducted on 23 patients of locally advanced HNC undergoing chemoradiation.Grade 2 mucositis onwards (RTOG grading) were exposed to low LLLT in a scanning motion 3-5 times weekly for 4 weeks Patients were assessed with intra oral photographs and Visual Analogue Score (VAS) questionnaire was used before and after LLLTto assess pain. Results: Eleven patients (47%) received 7 to 10 sessions of LLLT. Fifteen (65%) patients had grade three and seven (30%) had grade 2 before LLLT. Eleven and eight patients had grade 2 and 1 respectively after LLLT (p=0.007). Mean VAS score before and after LLLT was 6.32 and 3.32 respectively (p <0.01) Conclusion:LLLTis an effective intervention in patients with Grade 2 and 3 OM, both in terms of subjective and objective improvement
