PEMF may seem like a new technology, however it has been used throughout Europe and other countries for 50+ years. Over 2,000 double blind medical studies have documented the neurological, physiological and psychological positive effects of PEMF. It has repeatedly shown IMPROVED tissue repair in far less time, with NO adverse reactions. In fact, PEMF has received a boost in exposure since NASA used the therapy to treat astronauts.
The ergogenic athletic performance enhancement effects of our PEMF systems exceed anything reported in the scientific literature for increasing strength, stamina, VO2 Max or averting training-induced soreness. Unlike hypoxic training, hyperbaric oxygen or PEMF therapy systems, EarthPulse™ PEMF takes absolutely no effort at all other than turning it on when going to bed. It works synergistically with all nutritional programs and appears to qualify as an adaptogen and anabolic when paired with rigorous physical training.
Although PEMF therapy may seem like a novel technology, it has been safely and effectively utilized across America and Europe for over five decades. PEMF therapy is surrounded by more than 7,000 studies and clinical trials, including those from NASA, that have demonstrated the advantages of PEMFs. PEMF is a popular therapy used for better health and improved performance of both humans and animals worldwide.
As with back pain each of the possible contributing factors need to be examined and included in the treatment plan as appropriate (Kent et al 2005). This means that instead of lumping groups of symptoms together (e.g. rotator cuff symptoms) it has been suggested to split and recognise factors that cause laxity, impingement and/or lesion and provide treatment as the clinician sees fit. So far:
There are many scientific studies on the degree of effectiveness for pulsed electromagnetic fields therapy. It was found that disturbances in blood circulation and in metabolism play a key role in the development of diseases. Application of PEMF therapy, also called energy medicine, by pulsed electromagnetic fields with Curatron devices has a proven track record for more than 15 years.
Through PEMF therapy, your batteries (i.e. your cells) essentially become recharged. The energy supplied via PEMF waves gives them the energy they need to ward off whatever is threatening them, whether it’s a trauma or disease-based threat. This makes it easier for your patient’s body to restore its health naturally, simply by using the electrical currents and impulses that are already interacting within and throughout their cells. In essence, high-powered PEMF is like a “battery re-charger” for your depleted cells.
You may have heard that electromagnetic fields (EMFs) that come from things like wireless routers, microwaves, and airplanes disrupt your biology. EMFs can alter your DNA[1][2][3][4] and reconfigure your genes,[5][6] which can leave your cells not really knowing what to do. That can result in a lot of havoc, ranging from being tired all the time or ending up with DNA damage and cancer.[7]

Many people are aware of the negative effects Electro Magnetic Fields have but it is important to understand not all Electro Magnetic fields are bad and in the case of PEMF therapy we are using them to recharge our cells. Each cell in the body has its own small electromagnetic field with all our cells operating between around 0-30Hz. The Earth also has a magnetic field fundamental resonance frequency which is usually around 7.83Hz which is referred to the Schumann Frequency and this is the type of magnetic field our bodies have evolved to operate properly in. The problem is with increasing technology our world is getting filled with electromagnetic pollution that is filled with higher frequency electromagnetic fields our bodies are unable to properly function with and is making us sick.
The day before my wedding Dr. Pacelli performed a second examination with digital x-rays to the lower leg and right ankle. It was a fantastic day for the brake was almost completely healed. I should have known it for I was seen two to three times per week for six weeks and with each visit I was improving. The pain was now just a sore-aching feeling, the swelling was of a minor amount and the discoloration was gone.

Secondly, it has been proven that a PEMF has no adverse effects on the human body regardless of age, so it is safe to use on young children and babies. However, many patients have claimed feelings of discomfort for the first time they use PEMF therapy, but rest assured that this feeling is purely due to the detoxification effects of the PEMF which leaves and uncomfortable feeling as toxins are expelled.
Successful studies typically use frequencies between 1-100 hz and with some very specific applications up to 1000 Hz have been used. Our Earth's natural environment and occurring magnetic field's though is what we humans have evolved with and we require. This is the best indicator of suitable PEMF frequency to bring back the body into it's natural state. The primary Schumann resonance would have the most effect although the other resonance points would also have an effect.
Pulsed Electromagnetic Field Therapy (PEMF) uses electrical and magnetic fields to address a variety of health issues. Cancer is seldom found isolated from other conditions; many of our patients have multiple diagnoses, coupled with their cancer challenge. PEMF alleviates the pain, inflammation, and circulation issues associated with many of these conditions, allowing it to influence the outcome of cancer therapy protocol, both directly and indirectly.

Senbursa et al (2007) compared a home programme of rotator cuff and scapular strengthening exercises, active range of motion, and stretching with 12 sessions of glenohumeral soft tissue and joint mobilization, ice application, stretching and strengthening exercises in patients with impingement. At 4 weeks there were significant between group differences with regard to pain and function favouring the manual therapy group. Kachingwe et al (2008) showed significant changes with regard to pain, pain-free range of motion, and function for patients with impingement treated with 6 sessions of supervised exercise only, supervised exercise with glenohumeral grade I–IV glide and traction mobilizations from midrange, supervised exercise with a Mulligan mobilization with movement (MWM) shoulder flexion technique, or a control group receiving only physician advice; there were no between-group differences. Although power in this pilot study was extremely limited, the three intervention groups had a greater improvement in function and both manual therapy groups improved more with regard to pain measures. Active range of motion increased most for the MWM and least for the mobilization group.

PEMFs address impaired chemistry and thus the function of cells – which in turn, improves health. PEMFs deliver beneficial, health-enhancing EMFs and frequencies to the cells. Low frequency PEMFs of even the weakest strengths pass right through the body, penetrating every cell, tissue, organ and even bone without being absorbed or altered! As they pass through, they stimulate most of the electrical and chemical processes in the tissues. Therapeutic PEMFs are specifically designed to positively support cellular energy, resulting in better cellular health and function.

Enseignement constructiviste : L'enseignement constructiviste est une approche de l'enseignement dans laquelle l'élève est acteur de son propre apprentissage. L'enseignement constructiviste part du principe que l'élève a déjà des représentations (parfois fausses) sur ce qu'on souhaite lui enseigner et qu'elles peuvent bloquer la transmission du savoir. L'enseignant doit donc commencer la séance en faisant ressortir ces représentations et en mettant en place des situations qui invitent les élèves à les remettre en cause ou à les compléter. Cette remise en cause conduit à des situations de recherche et des échanges parfois enflammés entre les élèves. Une fois que ces recherches et ces échanges ont permis de construire un savoir plus élaboré, on procède à une phase dite d'institutionnalisation, c'est à dire que ce qui a été trouvé par une partie des élèves est validé par le groupe et évidemment par l'enseignant comme étant un savoir nouveau. La trace écrite de ce savoir nouveau est établie en faisant participer les élèves et devient alors une leçon. Comme cet enseignement prend pleinement en compte la grande différence qui existe d'un élève à l'autre, la préparation des leçons demande plus de réflexion et de travail que pour un enseignement transmissif.
In Magnetically Attractive Healing, Dr. David Williams called our v2 EarthPulse™  “The find of a century or two”, and called PEMF therapy in general “One of the greatest discoveries in the history of medicine.” We are currently in production of v5 EarthPulse™. The v5s are the most potent PEMF device systems we’ve ever developed. Now strong enough to work through any mattress up to 18 inches (45 cm) thick. Our pulsed electromagnet generates just the right amount of heat when trapped to the body, working synergistically with the pulsed electromagnetic field to help accelerate recovery by at least 50% of what would be considered normal for that situation.

“Paul – Well I have put the EarthPulse through enough testing that I can confidently say the device has real merit. There was for me a trial period so as to find out what settings worked best for my recovery. This has thus far been the results of my experimentation. Deeper sleep. 80% reduced hip pain. I can now sleep without throbbing pain. You have my full endorsement. God Bless.”
Cold applications diminish the inflammatory condition by acting as vasoconstrictors and reducing metabolic activity.118,119 Cooling also diminishes discomfort associated with the acute shoulder injury by increasing the threshold of pain in stimulated nerve fibers.120,121 Through this cold-induced analgesia, normal shoulder motion can be facilitated.122 Cold therapy can be effective with ice massage for 15 to 20 minutes with the arm positioned in abduction (Fig. 41-8).
Having experienced an MRS 2000 and Bemer, I wanted a mat and thought I was getting such a good deal with the OMI. I just want to share my disappointment so that you may benefit from my leaning. First, there is a noise that emanates from the mat and PEMF Supply will tell you that his is normal. Well it isn't with the MRS or Bemer. The noise sounds something like what you might imagine electricity running through a coil would sound. It belied any relaxation for me. Secondly, you will pay at least $225 (my loss in simply returning the system was $374.37) to return it. If you feel you have a faulty mat, you will pay $50 to send it to them to look at and another $50 to send it back to you. For a new product, I feel that is very poor customer service. In light of these aspects, I am not able to recommend the OMI system. If you still want to buy it, I would advise buying from Amazon since they have a return policy.
The EarthPulse is one of the most widely used PEMF device, and is primarily designed to facilitate deep delta rhythm sleep. Deep sleep causes recovery to accelerate and thereby reduces pain faster more naturally. The EarthPulse PEMF device is contrived to generate magnetic fields that “entrain” the brain by setting it in a cycle of regularized sleep rhythm. Thus it not only delivers PEMFs but also uses it in a much more effective manner by auto-shifting the frequencies to provide brainwave entrainment. It could just be the most effective brainwave entrainment tool too (and not just PEMF!). Brainwave entrainment basically means training your brain to operate at the best level of consciousness at any given time of the day. When a good circadian rhythm is established, the body performs best, recovery happens optimally and many types of pain vanish faster.
Once it was established that Ca2+ binding to CaM was a potential transduction pathway for PEMFs, the electrochemical model was employed to configure RF signals that would efficiently couple to Ca2+-binding kinetics28 using rate constants, which are well studied for the Ca/CaM system.39 This enabled the diathermy-based PEMF signal to be reconfigured so that its frequency spectrum more closely matched the dielectric properties of Ca2+-binding kinetics at CaM. The result is a PEMF device that uses 100 times less peak power to produce a biologically effective signal dose in the body. Initial confirmation of these predictions of the electrochemical model were reported for the MLCK enzyme assay, neurite outgrowth, and bone repair in a rabbit model.40 All of the limitations of the original diathermy-based devices were therefore addressed, potentially providing the physician with a more versatile and economical tool for postoperative pain and edema management with no known side effects.3
Although the results seem straightforwardly positive, the authors explain that “some of the effects of this therapeutic approach might be derived from neuromodulation of the pain mechanism”: that is, it might be “just” a pain-killer, as opposed to actually helping to heal arthritic cartilage. (But killing pain effectively would be a pretty good second place.)
The most recent studies of the PEMF transduction pathway have concentrated upon the Ca/CaM-dependent nitric oxide (NO) cascades. It is within this system that the effectiveness of PEMF is now understood to function. However, those linkages were dependent on the discovery that NO is a signaling molecule.41 NO is synthesized via nitric oxide synthase (NOS), that has several different isoforms.42 When injury occurs, large amounts of NO are produced by long-lived inducible nitric oxide synthase (iNOS). In this cascade, tissue levels of NO persist and the prolonged presence of this free radical is proinflammatory,43 which accounts for the leaky blood vessels associated with pain and swelling.44 In contrast, the endothelial and neuronal nitric oxide synthase isoforms (eNOS and nNOS, respectively) produce NO in short bursts that can immediately relax blood and lymph vessels.45,46 These short bursts of NO also lead to the production of cyclic guanosine monophosphate, which in turn drives growth factor production.47 Interestingly, iNOS is not dependent on CaM,43 while the constitutive or cNOS (eNOS or nNOS) cascade is dependent on the binding of Ca/CaM. Therapies that could accelerate Ca/CaM binding, therefore, should impact all phases of tissue repair, from initial pain and swelling to blood vessel growth, tissue regeneration, and remodeling.42
RASED : Le RASED, Réseau d'aide spécialisé aux élèves en difficulté, est une structure qui (quand il est complet) regroupe un psychologue scolaire, un maître E et un maître G. Les maîtres spécialisés interviennent auprès de petits groupes d'élèves en difficulté pour les aider dans leurs apprentissages (spécialité E) ou à mieux appréhender leur "métier d'élève" (spécialité G). Le psychologue scolaire a uniquement un rôle de diagnostic, de coordination et d'orientation vers les bonnes prises en charge. Il ne reçoit qu'après accord écrit des parents et ne fait pas de psychothérapie lui-même.
This entire range of effects because your cells and their mitochondria get an electronic “tune up” each night from the long duration exposure to these very-weak, frequency-specific pulsed electromagnetic fields. The mitochondria respond by improving cell respiration i.e. oxygen metabolism.  See our 10 Hz citations to learn about the mechanism; beginning with a 2 & 3 fold increase of the two key enzymes required for oxygen transport into and inside the mitochondria.

Given the recent rapid advances in the development of portable and economical PEMF devices, of most significance to the plastic surgeon has been the laboratory and clinical confirmation of decreased pain and swelling following injury or surgery.3,62 Indeed, PEMF configured for the Ca/CaM pathway has been shown to significantly accelerate postsurgical pain relief with a concomitant reduction in pain medications in a randomized, doubl-blind study in patients who underwent breast augmentation.3 Because of the unique biologic mechanism of the PEMF effect, this modality can be combined quite effectively with other therapies for additive or supradditive effects to promote pain relief, healing, and recovery. Treatment regimens may be manual or automatic and scheduled as frequently as every hour for particularly acute situations. The device is noninvasive and can be applied over a dressing; it and may even be part of a dressing for postoperative treatment of an incisional wound (Figure 5). Treatment begins in the recovery room and, to treat pain and edema, is generally administered every 4 hours for 30 minutes for 3 days, and then every 8 hours for the next several days until pain and edema are not significant. For the treatment of chronic wounds, the regimen is 30 minutes twice a day until healed.
The biophysical mechanism(s) of interaction of PEMF on biologic tissues and the biologic transduction mechanism(s) have been vigorously studied.27 One of the first models created was a linear physicochemical approach,22,24,27,28 in which an electrochemical model of the cell membrane was employed to predict a range of PEMF waveform parameters for which bioeffects might be expected. The most generally accepted biophysical transduction step is ion/ligand binding at cell surfaces and junctions that modulate a cascade of biochemical processes, resulting in the observed physiologic effect.25,29–31 A unifying biophysical mechanism that could explain the vast range of reported results and allow predictions of which PEMF signals and exposures are likely to induce a clinically meaningful physiologic effect has been proposed.22,28 The general application of this approach led to the BGS signal in use today. However, that signal is often only marginally effective because further dose quantification needed specific knowledge of the ion, the target site, its binding kinetics, and the cascade involved.
A simple way to understand the how EMFs impact our cells is comparing the EMF to a battery charger and our body to a large number of small batteries (our cells). Every battery is made to operate properly within a certain voltage range. If you overcharge the battery it will burn out, this is similar to what happens to our cells when exposed to high frequency EMFs our cells are not compatible with. In comparison if you use the correct Battery Charger voltage the battery will charge properly, this is what the correct PEMF does for our cells. PEMFs charges our cells with the energy they are designed to operate at and need to operate at their maximum potential. BAD EMF's will burn out our body cells and other illness's will cause effectively a discharging of our body cell's.

They back this statement by reporting that even hospitalized patients are at risk, with one out of every ten harmed while in what is supposed to be one of the safest medical environments. It only goes to reason then that safety is also a major concern and consideration for patients who are interested in PEMF therapy. So what’s the answer to the question of whether or not PEMF is safe?If you answer this question based on research alone, then PEMF is in fact a safe treatment remedy.

In aging and debilitated cells, the inflow of nutrients accompanied is also accompanied with a current of toxic fluids. It has been established that pain is felt as a result of the stimulation of peripheral nociceptors. When this stimulation occurs, encoded signals of distress are transmitted in an ascending pattern to the uppermost cortical structures.

The development of modern PEMF has followed two separate pathways. The first pathway originated in more conventional (and still useful) electromagnetic field technologies broadly known as radio frequency (RF) diathermy.4 Continuous RF produces heat, the therapeutic component frequently employed in physical therapy. One early user of diathermy suspected that it could produce a nonthermal biologic effect.5 To test this idea clinically, the RF signal was intermittently pulsed, thereby eliminating heat. Positive outcomes, especially in treating inflammatory conditions, were reported.5 The first therapeutic RF PEMF device, the Diapulse, was commercialized in 19506 and was eventually cleared by the U.S. Food and Drug Administration (FDA) for the postoperative treatment of pain and edema in soft tissue. Clinical devices in use since that time typically have consisted of a large signal generator and a bulky coil applicator positioned over the area of injury that delivers therapy noninvasively, through either dressings or clothing. Early devices were expensive, nonportable, and produced significant electromagnetic interference (EMI); these factors restricted more widespread use in outpatient and home settings.

My experience as a physio in the community has involved lots of work with Parkinson's and increasingly I see the effects of stress and the social engagement system being critical to understanding and improving movement, and in the last 3 years have done much more work with body awareness during activity, whether it be gaining flexibility or strength or balance. The toughest part is engagement especially when the general physio community is not promoting the same message. As you're website implies, it requires such a commitment to your well-being. I totally admire your perseverance and have empathy for how challenging it must be for you at times. 

This article continues my series which looks at recent scientific advances in understanding Parkinson's Disease, and then considers the pragmatic outcomes which people affected can apply at home, in our time. In the previous instalment, we looked at how the brain's of people with PD are "noisy", being dominated by busy, anxious beta brainwave frequency activity:
Taping patients may support retraining of correct movement patterns. However, using asymptomatic subjects Cools et al (2002) showed that tape application intended to inhibit the upper and facilitate the lower trapezius had no effect on electromyographic activity in the serratus anterior or all three portions of the trapezius with resisted or un-resisted flexion and abduction of the shoulder. The authors suggested altered timing as a possible explanation for the clinically observed effects of taping. In contrast, in patients with subacromial impingement Selkowitz et al (2007) did show that similar taping decreased upper trapezius and increased lower trapezius activity during a functional overhead-reaching task and that it decreased upper trapezius activity during shoulder abduction in the scapular plane. Mechanisms suggested to be involved in taping include facilitation or augmentation of proprioceptive cutaneous input, tension when movement occurs outside of the movement pattern allowed by the taping application, and inhibition or facilitation by taping shortened overactive muscles in a lengthened position, whereas the tape might be used hold lengthened under-active muscles in a shortened position. Various taping techniques appropriate for patients with impingement have been described in the literature (Morrissey 2000, Kneeshaw 2002) (Fig 16.5). Morrissey (2000) suggested that when the positive effect on the movement pattern or on symptoms was maintained, taping could be discontinued.
What does it promise? A technology first used by vets to treat injured racehorses, the electromagnetic charges thrown out by PEMF equipment are thought to stimulate your body’s cells, which can aid recovery from injury, reduce headaches, improve your immune system and blood circulation, provide improved sleep, and boost your general energy. People swear by it. Admittedly, one of those people is Noel Edmonds.

As we can see, long-term pulsed magnetic field therapy has been proven to be safe, so you should be able to proceed with using it without any issues, especially if it makes you feel better. Remember, listen to your body and when in doubt always consult a professional who knows about using PEMF treatment. Approaching professionals who do not have experience with a particular type of treatment will almost always be counter-productive as they will not be able to guide you with a protocol they don’t understand. At such times, it’s good to help us spread awareness and ask them to subscribe to our blog.

The Earthpulse™ PEMF generator is small and portable, yet stronger than all but the large and non-portable $10,000+ pulsed electromagnetic field therapy device systems. Strong enough to effectively penetrate a 16 – 18 inch (40 – 45 cm) thick mattress. A steep enough electromagnetic pulse to induce microampere current in tissue, yet small enough to easily fit in a handbag or briefcase; at a fraction of the cost of low-energy mat based pulsed electromagnetic field therapy device systems.

Diathermy-based RF PEMF has been employed in (1) double-blind clinical studies for chronic wound repair, in which actively treated pressure ulcers closed by 84% versus 40% in sham-treated wounds in one study7 and 60% versus no closure in the control group in another study8; (2) studies showing that a decrease in edema in acute ankle sprains was sevenfold versus the control group9,10; (3) studies showing a pain decrease in acute whiplash injuries of 50% and a range of motion increase of 75% in treated versus control patients11,12; (4) skin microvascular blood flow studies, in which blood flow was enhanced by about 30% in both healthy13 and diabetic14 individuals; and (5) studies in which postmastectomy lymphedema was reduced by 56% and skin blood flow increased fourfold.15

Magnetic Field Intensity can be measured for both “Static” and “Dynamic” magnetic fields. PEMF is a dynamic magnetic field and can be measured with a suitable instrument. The Earth's core magnetic field (which you can see from a compass reading) is a static magnetic field and it is approximately 250-650 milliguass strength and varies at different locations on the earth.

This was a rigorous test of wearable pulsed electromagnetic fields (PEMF) for older patients with osteoarthritis of the knee: moderate to severe cases with X-ray evidence and pain of at least 4/10 for more than six months, despite maximum tolerated medication. Sixty patients wore either a real PEMF device for 12 hours per day, or a fake; neither they nor the researchers knew who got real PEMF (double-blind). PEMF is particularly easy to test properly, because it causes no sensation, making it much easier to compare to an active placebo.

EMFs fall on a wide spectrum — everything from x-rays and satellites to your wireless headphones emit EMFs at different frequencies. High-frequency EMFs, like X-rays that register frequencies in the hundred quintillion Hz range (yes, that’s a number and it’s big) are the most disruptive to your body. That’s because they are ionizing — which means they have enough energy to break electrons off of atoms, which charges them. This changes the way your cells work.

"PEMF therapy improves PD symptoms including tremor, slowness of movement and difficulty in walking. It is non-invasive, safe and improves PD patients’ quality of life. PEMF therapy, employed for PD treatment, supports the body’s own healing process for 4–6 h after therapy session. It can be used at home and applied to the entire body or locally to target a specific body area and, if compared with dopaminergic systemic therapy, e.g. l-dopa, it can offer an alternative treatment avoiding systemic side effects such as hepatotoxicity and nephrotoxicity."

Low-intensity pulsed ultrasound (LIPUS) has been shown to have significant beneficial skeletal effects. Ultrasound refers to a high-frequency nonaudible acoustic energy that travels in the form of longitudinal mechanical waves. Traditionally used by physical therapists to intervene in injuries to soft tissues, it is most commonly used with intensity in the range of 0.5–2.0 W/cm2. In comparison, to intervene in injuries to hard tissues (such as bone) pulsed-wave ultrasound with a spatially averaged, temporally averaged intensity (ISATA) of below 0.1 W/cm2 is preferred. ISATA refers to the average ultrasound power over the area of the ultrasound beam (spatial-average) and the average of this intensity over a complete pulse cycle (ultrasound ‘on’ and ‘off’ period; temporal average). Pulsed-wave ultrasound with an ISATA below 0.1 W/cm2 is termed LIPUS and is preferred in the intervention of fracture healing, as its low ISATA significantly reduces the risk of any thermal or cavitational tissue damage—LIPUS has US Food and Drug Administration approval to be applied to bone.

Le fonctionnement d'une classe Freinet va réellement bien au-delà de la simple utilisation des fichiers PEMF. Ainsi, l'apprentissage de la lecture y passe AVANT TOUT par l'acte de production d'écrit. Les textes libres pouvant ensuite (ou non) servir de base à l'apprentissage de la lecture, dans une démarche de lecture naturelle (que je ne pratique pas pour ma part). Les fichiers de lecture PEMF, à la différence des fichiers maths, me semblent plus venir en complément de ce qui est fait en classe que comme base de travail. En cela, je ne les utiliserais pas dans l'idée de couvrir le programme de lecture en CP, mais plutôt comme outil de différenciation.
