ZIL : Le ZIL est un professeur des écoles titulaire remplaçant qui s'occupe essentiellement des remplacements courts, urgents et non prévus. Mais il peut aussi remplacer sur des congés maternité. Lorsqu'il n'a pas de remplacement, il reste dans son école de rattachement où il aide ses collègues. Le ZIL se déplace en théorie dans un rayon de 20km autour de son école de rattachement, en pratique dans toute sa circonscription.
PEMFs are frequency-based, applied to either the whole body or parts of the body. PEMFs may only be needed for short periods of time, while the effects last for many hours, setting in motion cellular and whole-body changes to restore and maintain balance in metabolism and health. The body does not acclimate, or “get used to,” the healthy energy signals of therapeutic PEMFs, even if used for a long time, compared to magnets.
Female subjects must be post-menopausal, surgically sterile, abstinent, or practicing (or agree to practice) an effective method of birth control if they are sexually active for the duration of the study. (Effective methods of birth control include prescription hormonal contraceptives, intrauterine devices, double-barrier methods, and/or male partner sterilization).
Patients and methods: A randomized, double-blind, sham-controlled, multicenter study in 36 subjects with persistent low-back and/or radiating leg pain after lumbar surgery was conducted. Eligible subjects were randomized (1:1:1) to receive one of two doses of therapy (42-μs or 38-μs pulse width) or treatment with a sham device. Subjects self-treated twice daily for 60 days. The primary end point was change in pain intensity (∆PI) using the Numerical Pain Rating Scale between average baseline (Days −5 to −1) and end of treatment (Days 56–60) for lumbar and radiating leg pain. Secondary outcome measures included the Oswestry Disability Index, Beck Depression Inventory-II, Patient Global Impression of Change, and consumption of analgesics.
Bone regeneration can be accelerated in osteotomies made 3.5–4.5 cm distal to the head of the fibula in dogs. A voltage field was induced in the fibula by inductively coupling pulsed electromagnetic fields of low frequency and strength directly to the bone across the skin. Not only did the stimulated osteotomies heal faster than control osteotomies but the regenerated bone was also more highly organized and stronger than control regenerated bone, even though the mass of callus formed was less than in controls. This method has been used to successfully treat tibial pseudoarthroses in young patients. Pseudoarthrosis is a rare, local bone dysplasia that has a very low probability of correction by conventional techniques. Pulsed electromagnetic fields have also been used as a noninvasive postoperative treatment for lumbar vertebral fusion.
Using outcome measures such as the Upper Extremity Functional Index (Stratford et al 2001) or the Croft Disability Questionnaire (Croft et al 1994) do not measure pain and disability associated with overhead activities as the SPADI does. Although cross-sectional comparison of different shoulder questionnaires can show comparable overall validity and patient acceptability, it is important to include overhead activities since overhead work is an important aspect of her daily work. An additional benefit of the SPADI is that it is responsive to change, quick to complete, and scores are not likely to change in stable subjects (Paul et al 2004).
A PEMF device furnishes an external pulsed electromagnetic field that facilitates the optimum electromagnetic environment for cells to regulate the inflow and outflow of electrically charged ions in tissues. Due to enhanced cellular performance, cell membranes are invigorated, this is how Pulsed Electromagnetic Field (PEMF) therapy improves oxygenation and nutrient absorption in body cells. The pangs and throes of pain can be conceived of as signals that permeate our consciousness, alerting us of endangered cells and tissues in our bodies.

It can now be considered the most affordable whole body PEMF device for home use. Our PEMF therapy devices are shipped worldwide from US & EU and come with a best-in-class 30 day money-back guarantee.
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.
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.
It is interesting to note that one of the authors (BS) showed significant increases in angiogenesis in an arterial loop model in the rat using the early diathermy-based RF device (Figure 2).51,52 It is also interesting that the use of the BGS signal on human umbilical vein endothelial cells in culture significantly augmented tubule formation53 via a PEMF effect on the production of fibroblast growth factor 2 (FGF-2). When FGF-2 was inhibited, the PEMF effect disappeared. This study was extended to examine the effect of BGS on wound repair in diabetic and normal mice,54 in which it was also shown that PEMF significantly increased neovascularization, particularly in diabetic mice, via endogenous FGF-2 increase.
Within 10-14 days our clients routinely find they have more strength and stamina than they’ve had in decades – or ever in their life. If at your genetic peak, you can stop age-related degradation while setting new personal performance records. If you’re over or feeling over-the-hill, we’ll have you feeling a decade (or two) younger in 90 days or return it.
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.
