Pulsing electromagnetic field represents effective procedure in treating of diverse diseases and pathologic conditions, especially in rheumatology, orthopaedics and traumatology. The goal of this research is the objective evaluation of the treapeutic effect of low frequency pulsing electromagnetic field (LFEMF), in comparison with the effect of the other physical procedure: interfererence currents (IFC) and the medicamentous therapy, in treating of patients with knee joint osteoarthritis. This study was made as experimental, randomized, controlled clinical trial, opened type. The examination included 60 patients (40 females and 20 males) with osteoarthritis of the knee joint. All patients were divided in three groups. The first group of 20 persons, composed of patients treated with medicamentous therapy (Diklofenak of 100 mg, 2 tablets per day). The second group consisted of 20 patients treated by LFPEMF and the third group consisted of 20 patients treated by IFC. All procedures were implemented during 10 days All of patients had also the same duration therapeutic exercise. As observing parameter was used: Lattinen test for the evaluation of the pain sensitivity, before and after therapy. For the statistical analysis of the aquired data, was used Student?s t-test. After therapy the pain was considerably reduced in each group, but this effect was the most significant in the II group of the examinees, treated by LFPEMF (p< 0.001), than the effects in other groups of patients: I group (p< 0.05) and III group (p< 0.01). According to the results of this study it can be concluded that LFPEMF is very effective therapeutic procedure in treatment of patients with knee joint osteoarthritis.

Introduction: Osteoarthritis (OA) is a widespread disease among adult population and is one of the major public health problems. OA is leading cause of disability the joints of lower limbs: knee and hip. As global life expectancy increases, it predicted that OA will be the leading cause of damage resulting in permanent disability. In cases of OA a reduction in cartilage tissue is observed, which is radiographically demonstrated by narrowing of the joint space and bone changes, osteophytes and subchondral bone sclerosis. However, a significant proportion of patients with radiological evidence of gonarthritis do not report joint pain. It is important to evaluate the changes occurring in the surrounding tissues. Muscle weakness of m. quadriceps femoris may occur before pain and impaired joint function. The development and application of new non-pharmacological methods in the rehabilitation of degenerative joint diseases is particularly important.Purpose: To establish the short-term therapeutic effects of treatment with Low-frequency and Low-intensive electrostatic field, applied through Deep Oscillation® method and complex of therapeutic exercises in rehabilitation of patients with osteoarthritis of the knee.Materials and methods: We conducted a one-year observational study involving 23 patients with clinical symptoms and radiologically proven II and III stage according Kellgren-Lawrence gonarthritis, aged between 42 and 78 years, were observed. 15 of them were women average age 61.73±12.9 years vs 8 - males average age 61.75±9.6 years (p=0.997). The duration of the current pain-episode was 1.7±0.7 months. The treatment was conducted in 10 sessions and included: Low-frequency and Low-intensity electrostatic field and complex therapeutic exercises.Results: The results were evaluated before and after completion of therapeutic course by assessing pain (VAS) at rest, when walking, climbing and descending on stairs, Manual Muscle Testing, Measurment of the knee joint circumference, Test Range of Motion and WOMAC Osteoarthritis Index, V.LK 3.1. were tracked. For processing statistical data SPSS v.13 was used. There was a statistically significant reduction of pain syndrome at rest (p<0.001), walking (p<0.001), descending stairs (p<0.001), climbing (p<0.001). Reduction of knee joint circumference (p<0.001). Increasing the range of flexion before Ме (Range) from 105º (90º-120º) versus 120º (100º-125º) after therapy. Reduced deficiency at an extension from 3.48 ± 4.38 before therapy to recovery of the extension. Improved total WOMAC Index (p<0.001), Stiffness (p<0.001) and Function (p<0.001).Conclusion: The short-term effects of the application of Low-frequency and Low-intensive electrostatic field in complex with therapeutic exercises show reduction of clinical symptoms and improvement of daily functional activity in patients with knee joint osteoarthritis. Reduction of pain of rest and physical activity (walking, descending and climbing stairs) is observed, oedema is reduced, joint range of motion increases, immediately after completion of the therapeutic course. Because of the small number of patients included in the study for better objectifying of the effects of the low-frequency and low-intensity electrostatic field, the studies should continue.

Transcutaneous electroneurostimulation is an effective method of chronic pain relief. Dynamic electrical neurostimulation is a type of transcutaneous electroneurostimulation based on the use of weak (200–400 mkA) low frequency (10–200 Hz) pulse currents. A feature of this type of physiotherapy is the pulse shape, which changes following the change of the total electrical resistance of underelectrode skin area, which enables prolonged use without “addiction”. A multicenter randomized double-blind placebo-controlled study with 132 patients was conducted. Dynamic electrical neurostimulation led to a rapid decrease in the intensity of pain in the knee joint by an average of 5–8 mm on a visual-analogue scale immediately after the end of the procedure in the absence of pain dynamics of the procedure performed by the placebo. After completing the course of treatment from 10 procedures during the month of follow-up, the intensity of pain according to visual-analogue scale in patients of the dynamic electrical neurostimulation group was lower than in placebo. The decrease in pain intensity was also accompanied by a decrease in the time of the “Get up and go” test and an improvement in the Leken index. The statistically significant difference between the groups in the time of the “Stand up and go” test appeared at the end of the course of therapy and persisted for a month after the end of the course of therapy. Dynamic electrical neurostimulation is an effective and safe method for reducing pain and improving the function of the knee joint in patients with osteoarthritis.

Abstract Objective: The present study was to investigate the effect of low-frequency electrical stimulation on disuse muscle atrophy and its mechanism in a rabbit model of extending knee joint contracture.Methods: This study designed two experiments. In the time-point experiment, 24 rabbits were randomly divided into Control 1(Ctrl1), immobilization for 2 weeks (I-2), I-4, and I-6 groups. In the intervention experiment, 24 rabbits were also randomly divided into Control 2 (Ctrl2), electrical stimulation (ES), natural recovery (NR) and electrical stimulation treatment (EST) groups. All intervention effects were assessed by evaluating the knee joint range of motion (ROM), cross-sectional area (CSA) of muscle and the expression of autophagy-related proteins.Results: Time-point experiment showed that immobilization reduced knee ROM, muscle CSA, and activated autophagy in skeletal muscle. Levels of four autophagic proteins including p-mTOR, Atg7, p62 and LC3B-II, were significantly elevated in the skeletal muscle of I-4 group. The intervention experiment further presented that LFES significantly improved the immobilization-induced ROM and CSA reduction. Additionally, LFES significantly reversed autophagy activation of skeletal muscle caused by immobilization.Conclusions: Low-frequency electrical stimulation alleviates immobilization-evoked disuse muscle atrophy maybe via inhibiting autophagy in skeletal muscle of rabbits.

Damage to the knee joints in children is up to 25% of all injuries of the musculoskeletal system. Currently, physical factors used in medical rehabilitation of children with traumatic injuries of the knee joint are primarily aimed at stopping the inflammatory process, and physiotherapy technologies with a pronounced analgesic, lymphatic drainage effect are not sufficiently developed. For the first time, a new pathogenetically substantiated technology for medical rehabilitation of children with traumatic arthropathy of the knee joint using a pulsed low-frequency electrostatic field was developed. The beneficial effect of a pulsed low-frequency electrostatic field on the indicators of orthopedic status, psychological processes, the state of microcirculation and thermography in the area of damage has been established.

Sounds produced by the articulation of joints have been shown to contain information characteristic of underlying joint health, morphology, and loading. In this work, we explore the use of a novel form factor for non-invasively acquiring acoustic/vibrational signals from the knee joint: an instrumented glove with a fingertip-mounted accelerometer. We validated the glove-based approach by comparing it to conventional mounting techniques (tape and foam microphone pads) in an experimental framework previously shown to reliably alter healthy knee joint sounds (vertical leg press). Measurements from healthy subjects (N = 11) in this proof-of-concept study demonstrated a highly consistent, monotonic, and significant (p < 0.01) increase in low-frequency signal root-mean-squared (RMS) amplitude—a straightforward metric relating to joint grinding loudness—with increasing vertical load across all three techniques. This finding suggests that a glove-based approach is a suitable alternative for collecting joint sounds that eliminates the need for consumables like tape and the interface noise associated with them.
