The aim of the study was to identify the features of the course of repair processes in myometry under the influence of selective pulsed electrostimulation as a monomethod and in combination with system-wide magnetotherapy according to ultrasound data in patients after myomectomy. The study included 105 patients aged 28 to 59 years after myomectomy. All patients were divided into 3 groups of 35 people: the control group did not receive physical therapy. Patients of the main group with 2 days after surgery was carried out, the total magnetic therapy with the duration of 15 minutes, at the rate of 10 daily procedures in combination with the selective pulsed electrical stimulation currents of low frequency with a duration of 25 minutes, at the rate of 10 daily procedures; patients in the comparison group from the 2nd day after surgery was conducted by selective pulsed electrical stimulation currents of low frequency, duration 25 minutes, at the rate of 10 daily procedures. In the study it was found that the most pronounced stimulation of regenerative processes and proper formation of postoperative scar in patients in the early postoperative period after myomectomy was noted under the influence of complex application of General magnetic therapy in combination with selective pulsed electrical stimulation currents of low frequencies through tristimulous and regenerative eff ects are somewhat less significant results were obtained when monophospate selective pulsed electrical stimulation currents of low frequency. The obtained results indicate the prospects of including the developed complex in the programs of early rehabilitation of patients after myomectomy to improve the flow of regeneration processes in the myometrium and prevent the development of suture failure.

Promising Therapeutic Approach

Acute urinary retention (AUR) is a troublesome urological disease, which causes various lower urinary tract symptoms. However, only few studies explored and evaluated the effective treatments to improve AUR. We aimed to find an effective approach to cure AUR through comparing the efficacy of existing classical low-frequency transcutaneous electrical nerve stimulation (TENS) and novel intravesical electrical stimulation (IVES). A total of 24 AUR female rats were divided into 3 groups as follows: control, TENS, and IVES groups. Rats in the control group had no fake stimulation. Rats in the TENS and IVES groups underwent transcutaneous or intravesical stimulation of a symmetrical biphasic rectangular current pulse with a frequency of 35 Hz, 30 min per day, for seven consecutive days. IVES significantly reduced the actin expression in the submucosal layer but increased its expression in the detrusor layer (p= 0.035,p= 0.001). The neovascularization in the submucosal layer in the IVES group was significantly increased than in the other 2 groups (p= 0.006). Low-frequency IVES performed better than TENS in terms of simultaneously relieving bladder hyperactivity, accelerating epithelial recovery, and strengthening detrusor muscle. IVES may be a promising therapeutic approach for bladder dysfunction, specifically for AUR and overactive bladder in clinical practice.

Low frequency fatigue (LFF) in 12—14 year-old adolescent boys (n = 10) doing 75 eccentric jumps performed every20 s from a platform 80 cm high was investigated.Thus the aim of this study was to find out if LFF manifests itself in the muscles of boys aged 12—14 years doing 75 dropjumps performed every 20 s at angles of 90˚ and 135˚ from a platform 80 cm high. The results of the research have shownthat doing 75 eccentric jumps performed every 20 s calls forth LFF in the muscles of boys that is particularly strong anddisappears more slowly at a shorter length of the muscle exercised. Thus, the hypothesis as to the sarcomeric origin ofLFF in the muscles of boys and men has been confirmed. Besides, the muscles of men of mature age are more resistantto LFF than those of boys. This fact, as well as a more acute pain brought about in the muscles of boys, indicates thatthe muscles of boys are less resistant to mechanical damage than those of men of mature age.It is maintained that as a result of the eccentric exercise performed, some portion of the weak sarcomeres gets tornand then the strong sarcomeres, i.e. the ones that develop contraction force have to work at a shorter muscle length.When muscle contraction length is short the sensitiveness of miofibrillas to Ca 2+  decreases. It is rather unexpectedthough that 24 h after the end of the exercise the force developed by electrostimulation at low frequencies (20 Hz) issmaller (p < 0.05), as compared to the initial force registered at a shorter muscle length. Since after the exercise therewas also a decrease in the force developed at a shorter muscle length in particular, the sarcomeres are believed tohave been damaged during eccentric exercise.Keywords: electrical stimulation, force, age, muscle damage, stretch-shortening exercise.

Stimulation Paradigm

In this study, we present a novel low-frequency electrical stimulation paradigm for mesial temporal lobe epilepsy (MTLE). The paradigm utilizes the hippocampal commissure as a unique stimulation target to simultaneously influence large portions of the bilateral hippocampal network. When applied to an acute rat model of MTLE, animals that received stimulation exhibited an 88% reduction in the signal power of the bilateral epileptiform activity relative to the control group. In addition, the stimulation entrained the hippocampal network's spontaneous epileptiform activity and disrupted its bilateral synchrony.

Background: Recent research has discussed the use of low-frequency electrical stimulation to increase blood flow by eliciting muscular contraction in soft tissues. This randomized clinical trial examined the efficacy of low-frequency electrical stimulation combined with stretching exercises and foot orthoses in individuals diagnosed as having plantar fasciitis for less than 6 months. Methods: Twenty-six participants aged 18 to 65 years diagnosed as having plantar fasciitis were randomly assigned to two treatment groups: a control group receiving only stretching and orthoses and a treatment group receiving low-frequency electrical stimulation in addition to stretching and orthoses. To assess treatment response, a visual analog scale was used to determine first-step morning pain, and changes in daily activity levels were monitored by using a validated outcome measure. All of the participants were assessed before starting treatment, after 4 weeks of treatment, and 3 months after the conclusion of treatment. Results: Participants in the control and experimental groups demonstrated pain reduction and improvements in functional activity levels after 4 weeks and 3 months. Conclusions: Regardless of whether low-frequency electrical stimulation was used as an intervention, the use of plantar fascia–specific stretching and prefabricated foot orthoses provided short-term (3-month) pain relief and improvement in functional activity levels.

Exercise Fatigue

Objective The motor cortex (MC) stimulation-induced unitary responses of globus pallidus external segment (GPe) neurons in control and exercise induced-fatigue rats were recorded in vivo to examine the role of cortical-striatum-external globus pallidal pathway in the mechanism of central fatigue. Methods 32 Clean healthy male Wistar rats (260~300g), were randomly divided into 4 groups: control group (Control), 1-day fatigue group (1FG), 3-day fatigue group (3FG) and 7-day fatigue group (7FG). Rats were subjected to a 5-day adaptive treadmill training. Modified Bedford treadmill exercise with progressively increasing load was used to creat the exercise fatigue model. （3 levels:8.2 m/min, 15 min; 15m/min, 15 min; 20 m/min, lasting till exhaustion） The spontaneous unit activity and responses to MC stimulation of GPe neurons were recorded by the electrophysiological technique of extracellular recording of glass microelectrodes. Results The results showed that the firing frequency of high-frequency firing with pause (HFP) and low frequency firing with burst (LFB) in the GPe of 1FG was comparable with that of control group (P>0.05). However in 3FG and 7FG , the percentage of HFP neuron was significantly decreased (P<0.05), while the proportion of LFB was significantly increased (P<0.05), and the average firing rate of LFB was higher and inter spike intervals (ISI) was significantly lower than that of the control group. With 200μA electrical stimulation, the explosive discharge of GPe neurons was attenuated after fatigue in rats. The response of GPe neurons to variable frequency stimulation in exhausted model groups was stronger than that of the control group.MC-stimulation typically induced a triphasic response composed of early excitation, inhibition, and late excitation in GPe neurons. The population of neurons showing a short inhibition slightly increased in 3FG and 7FG. Conclusions 1. The results confirmed that GPe is an important nucleus of basal ganglia involved in the regulation of exercise-induced fatigue by the change of spontaneous activity. Electrical stimulation on the cortex can alter response patterns of GPe neurons in exercise-induced fatigue rats, the results confirmed that the Ctx-Str-GPe neural pathway is involved in the regulation of exercise fatigue, and the indirect pathway is over-activated.

Low Frequency Fatigue

During and following high-load fatiguing voluntary contractions, the force response of skeletal muscle to electrical stimulation is altered so that the frequency-force curve is moved to the right. Fatiguing contractions also result in a shift to the left of the electromyographic (EMG) power spectrum. In the quadriceps muscle and the diaphragm of normal subjects the change in the force response to electrical stimulation has been correlated with the EMG changes. After repeated submaximal contractions in the quadriceps and diaphragm, the forces produced by electrical stimulation at low frequencies were reduced, indicating low-frequency fatigue. This type of fatigue persisted for several hours but did not result in any change in the EMG high-to-low ratio. Low-frequency fatigue is probably an important aspect of the failure of skeletal muscle to generate adequate force, and the EMG high-to-low ratio may not recognize this type of fatigue.

The Impact

<p class="abstract">Noise induced hearing loss (NIHL) is regarded as a serious problem and one of the most recorded occupational disorders in Europe and in the rest of the world and amounts to between 7% and 21% of the hearing loss. Aim of this study is to explore the development and the prevalence of low frequency noise-induced hearing loss (NIHL) in a hospital, especially in microbiology laboratory workers. Generally it is known that 4 KHz is the main NIHL frequency. Despite current theories, our study suggests for the first time the impact of low frequency noise in hearing loss among laboratory workers. According to the results, the population examined, namely the employees at the Microbiology Department of the Hospital, showed lower hearing levels compared to the control group, who had no history of occupational exposure to noise. There are many other studies which suggest that prolonged exposures to high noise levels have negative physiological and psychological effects on workers. The finding of the correlation of noise frequency with the frequency of the generated hearing loss is involved in the controversy about the pathophysiology of noise effect.</p>

Experimentally Induced

24 recent studies on acupuncture analgesia for the relief of experimentally-induced pairs are reviewed. Negative or equivocal results are reported in 7 of these. The remaining 17(71%) report significant analgesic effects during manual or electrical stimulation (particularly at very low frequencies on the order of 2 Hz) at acupuncture loci. Many investigators note that the full analgesic effect is attained only after about 20 minutes of stimulation. Furhter investigation of the analgesic effects of stimulation at acupuncture loci, particularly the effect of very low frequency electrical stimulation, is fully warranted by these preliminary findings.

Spontaneous Correction

Breech presentation was successfully corrected by stimulating acupuncture points with moxibustion or low-frequency electrical current. Only patients with breech pregnancies at the 28th week or later were entered into the study. With moxibustion treatment, the control group had a spontaneous correction rate of 165/224 (73.66%), and the treatment group had a correction rate of 123/133 (92.48%) (P < 0.0001, x2 test). With low-frequency percutaneous electrical stimulation, the correction rate was 20/941 (83.87%) in the control group and 171/191 (89.52%) in the treatment group (P = 0.094, x2 test). The control is the moxibustion study did no exercises and received no external manipulation to correct breech presentation whereas those in the electrical stimulation study experienced both. Acupuncture stimulation, especially with moxibustion, is expected to serve as a safe and effective modality in the management of breech presentation in a clinical setting.
