The basic science work accomplished to date provides strong support for the proposal that modulation of Ca2+ binding to CaM, upon a transient increase in intracellular calcium when homeostasis is interrupted,48 is an important PEMF transduction pathway. It is likely that the disruption of the tightly regulated Ca2+ balance in cells is the natural signal to provoke the endogenous tissue repair and regeneration mechanism, hence the apparent simple acceleration of normal healing activity by targeted PEMF signals. Ca/CaM catalyzes eNOS, which allows the PEMF signal to modulate the release of NO from eNOS and potentially affect the entire tissue repair pathway, from pain and edema to angiogenesis, bone and tissue regeneration, and other regenerative actions. PEMF signals configured to target the Ca/CaM pathway have been applied to rat tendon and wound healing.49,50 In both studies, tendon and wound healing rates were seen to significantly increase by 59% ± 4% (Figure 1, A) and 69% ± 5% (Figure 1, B) in PEMF-treated animals.
There is nothing new about Electromagnetic therapy. It has been around for over 100 years, according to James L. Oschman PhD, in Energy Medicine (Second Edition), 2016, it has been used by the former Soviet Union as complementary treatment to pharmacology. Pulsing electromagnetic field therapy was used by the cosmonauts during the Soviet space explorations, to help reduce the loss of bone density that occurs when they were removed from the Earth’s gravitational and magnetic fields.
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).
Cognitive functioning after repetitive transcranial magnetic stimulation in patients with cerebrovascular disease without dementia: a pilot study of seven patients; Rektorova; J Neurol Sci. 2005 Mar 15;229-230:157-61 This study aimed to examine whether one session of high frequency repetitive transcranial magnetic stimulation (rTMS) applied over the left dorsolateral prefrontal cortex (DLPFC) would induce any measurable cognitive changes in patients with cerebrovascular disease and mild cognitive deficits. Seven patients with cerebrovascular disease and mild executive dysfunction entered the randomized, controlled, blinded study with a crossover design. rTMS was applied either over the left DLPFC (an active stimulation site) or over the left motor cortex (MC; a control stimulation site) in one session. Each patient participated in both stimulation sessions (days 1 and 4) and the order of stimulation sites (DLPFC or MC) was randomized. A short battery of neuropsychological tests was performed by a blinded psychologist prior to and after each rTMS session. Psychomotor speed, executive function, and memory were evaluated. Results: mild but significant stimulation site-specific effect of rTMS was observed in the Stroop interference results (i.e. improvement) after the stimulation of DLPFC in comparison with the baseline scores (Wilcoxon, Z=-2.03, p=0.04). Patients improved in the digit symbols subtest of the Wechsler adult intelligence scale-revised after both rTMS sessions regardless of the stimulation site.

PEMFs have been in clinical use for generations. For most of that time, however, PEMFs have been relegated to second or even third tier status, with some ardent supporters, a number of skeptics, and most clinicians and patients simply unaware of their benefits. Without substantive information about a mechanism of action and frequently being the subject of overzealous marketing and inflated claims, PEMF devices lacked credibility. When the knowledge base in basic sciences allowed for the critical examination of PEMF in the laboratory and provided techniques for both targeting and engineering, the system advanced and the many effects of PEMF signals could be rationalized within at least 1 biologic cascade—one that is dependent on an electrochemical process and can be affected by exogenous signals. It was clear from this work that different PEMF signals and configurations produce widely different results depending on how well targeted those signals are to naturally occurring and biologically salient electrochemical processes. As this body of evidence grows and clinical experience widens, the gaps in the current knowledge (especially concerning optimal treatment regimens for specific conditions) will be filled. At the same time, we anticipate that improved signals and products that are more effective and more ergonomically designed will be developed, and that other electrochemical pathways will be targeted for additional indications. This may finally be the century of electrotherapy. In the meantime, plastic surgeons have at hand a powerful tool for the adjunctive management of postoperative pain and edema and wound repair. PEMF therapy is simple, cost-effective, has no known side effects, and may well play a large role in treatment of otherwise intractable wounds while reducing the cost of health care.

Pour les fiches PEMF, peut-être que le mieux c'est de mettre tout le monde en même temps du plan de travail et quand ils ont terminé une fiche, ils s'inscrivent à la correction et tu les appelles un par un à ton bureau? Et quand ils attendent la correction, ils font autre chose (autre fiche pemf ou remise au propre de texte libre, création mathématique ou autre?)
