Clinical Scenario:Tendinopathies plague many active individuals, causing pain and reducing sport activity by decreasing range of motion and strength. There are many modalities that have been used to treat pain associated with chronic inflammation, such as ultrasound, moist heat packs, and electrical stimulation. Low-level laser therapy (LLLT) is one such modality. Potential benefits of managing pain associated with tendinopathies have been investigated using LLLT. Cellular respiration and metabolism are thought to be increased by LLLT acting on the mitochondrial cytochromes. The effects LLLT may have on cellular activity could increase blood flow to progress the healing process by reducing the pain-spasm cycle. The purpose of this critically appraised topic is to identify the clinical effectiveness of LLLT on pain associated with tendinopathy and to identify the parameters used to achieve statistically and clinically relevant pain outcomes.Focused Clinical Question:What is the effect of LLLT on pain associated with tendinopathy?Clinical Bottom Line:Although LLLT significantly decreases pain from baseline, its use may be no better than placebo or traditional treatments such as ultrasound, moist heat packs, electrical stimulation, or therapeutic exercise to reduce pain associated with tendinopathy. Total accumulated joules across the treatment sessions may need to be taken into account as a parameter.

Background The combined effects of low-level laser therapy and neuromuscular electrical stimulation on knee osteoarthritis have yet to be analysed. This study aimed to determine the individual and combined effects of laser therapy and electrical stimulation on muscle activation and pain in older people with knee osteoarthritis. Methods A total of 45 women aged 60–75 years with knee osteoarthritis were randomised into three groups to receive stimulation, laser or stimulation plus laser therapy. All three groups underwent a 4-week control period (without intervention) followed by an 8-week intervention period. The effects of the interventions on muscle inhibition, electrical activity and pain were analysed. Findings There was a decrease in muscle inhibition (effect size ≥0.6) and a reduction in pain (effect size >1.2) in all three groups. All therapies generated an increase in electrical activity (effect size 0.1–0.5). Conclusions Laser alone or in combination with electrical stimulation promoted similar increases in muscle activation and pain relief.

Abstract Introduction. Neuromuscular electrical stimulation is applied in muscle atrophy and in muscle strength and endurance training in athletes. Muscle soreness and temporary reduction in muscle strength may occur as adverse effects. Laser therapy has been used as a method of counteracting delayed onset muscle soreness following volitional exercise, but not following electrical stimulation. The aim of the study was to determine whether low-level laser therapy applied prior to electrical stimulation accelerates the recovery of muscle strength and decreases the duration and intensity of muscle soreness at rest after intensive isometric neuromuscular electrical stimulation of the quadriceps femoris muscle. Material and methods. A randomised crossover trial was carried out on 24 healthy, recreationally active men aged 22-24 years. Low-level laser therapy or sham laser therapy was applied prior to a single session of neuromuscular electrical stimulation of the quadriceps femoris muscle with typical technical and training-related parameters. Irradiations were performed immediately prior to and shortly after electrical stimulation as well as 24, 48, 72, and 96 hours after this procedure. Muscle soreness was examined using the VAS scale in the same time periods. Quadriceps moments of force were recorded with the use of a Biodex 4 Pro device during maximum voluntary static contraction and during electrical stimulation that triggered a tetanic contraction of the quadriceps femoris muscle reaching the level of maximum tolerance. Results. No significant differences were noted in the severity of quadriceps soreness and in the magnitude of the decrease in the moments of force of maximum voluntary contractions after stimulation preceded by laser therapy and that preceded by sham irradiations. Conclusions. In the group studied, laser therapy applied before single electrical stimulation with typical parameters did not bring about a faster recovery of muscle strength or a more rapid decrease in soreness than sham laser therapy used prior to electrical stimulation. Further research on larger groups of subjects with the application of various procedures as well as research on training programmes is needed.

Breast cancer is the second most frequent cancer among women. Surgery is part of the therapeutic process to prevent metastases, but it can also cause some complications, including lymphedema. Physiotherapy contributes to its treatment, using different techniques that have been developed over the years. This systematic literature review aims to present physiotherapy modalities applied for lymphedema therapy. The literature review was conducted using textbooks and Lilacs, Pubmed and Scielo databases, from 1951 to 2009. Physiotherapy resources used for lymphedema treatment include complex decongestive therapy (CDT), pneumatic compression (PC), high voltage electrical stimulation (HVES) and laser therapy. The analyzed literature shows that better results are obtained with combined techniques. CDT is the most used protocol, and its association with PC has demonstrated efficacy. The new techniques HVES and laser present satisfactory results.

Background. The high recurrence rate after surgical treatment of pelvic organ prolapse makes it necessary to improve therapeutic methods. Objective: to develop and scientifically substantiate the use of a rehabilitation complex, including general magnetotherapy, electromyostimulation with biofeedback in combination with fractional microablative therapy with a CO2 laser, in patients of different age groups with rectocele after surgery. Methods. The article presents the treatment data for 100 women of childbearing, peri- and menopausal age with rectocele IIIII degree, which were divided into 2 groups comparable in terms of clinical and functional characteristics (main and control), within each group they were divided by 2 subgroups: subgroup A included women of childbearing age, subgroup B included women of peri- and menopausal age. The patients of the main group in the early postoperative period after plastic surgery for rectocella (from 1 day) underwent a course of general magnetotherapy and in the late postoperative period (one month after the operation) they performed a set of measures consisting of a course of electromyostimulation with biological connection of the pelvic floor muscles and a special complex physiotherapy exercises and 2 intravaginal procedures of fractional microablative CO2 laser therapy with an interval of 45 weeks. Patients in the control group after surgical treatment of rectocele in the late postoperative period received symptomatic therapy, including painkillers and antispasmodics, which served as a backdrop for patients of the main group. Results. As a result of the studies, it was found that regardless of the age and severity of uterine blood flow disorders in the uterine arteries in patients with rectocele, the most pronounced dynamics was observed in patients of the main group, which, in our opinion, is associated primarily with the vasoactive effects of general magnetotherapy, manifested in the removal of spasm from arteries and arterioles, improving the contractility of the veins and increasing venous outflow, which in combination with electrical stimulation, exercises to strengthen the muscles of the pelvis bottom and fractional microablative therapy allowed to obtain such a pronounced vasocorrigating effect. Conclusions. Due to the pathogenetic effect of the developed complex (electrical stimulation, exercises to strengthen the pelvic floor muscles and fractional microablative therapy) on one of the main mechanisms of the development of the disease, a pronounced vasocorrecting effect was obtained.

In studying quick-frozen single intact skeletal muscle fibers for structural and microchemical alterations that occur milliseconds, and fractions thereof, after electrical stimulation, we have developed a method to compare, directly, ice crystal formation in freeze-substituted thin sections adjacent to all, and beneath the last, freeze-dried cryosections. We have observed images in the cryosections that to our knowledge have not been published heretofore (Figs.1-4). The main features are that isolated, sometimes large regions of the sections appear hazy and have much less contrast than adjacent regions. Sometimes within the hazy regions there are smaller areas that appear crinkled and have much more contrast. We have also observed that while the hazy areas remain still, the regions of higher contrast visibly contract in the beam, often causing tears in the sections that are clearly not caused by ice crystals (Fig.3, arrows).
