International Animal Company Att.: Klaus Abel Fanefjordgade 152 4792 Askeby Preliminary literature search relating to Care4Life to substantiate clinical benefits PubMed search 8. October 2013 Search terms identified via Pubmed/MeSH: 1) electromagnetic fields [MeSH] 2) electromagnetic field 3) osteoarthritis [MeSH] 4) pulsed Search string used: "electromagnetic fields"[mesh Terms] OR electromagnetic field[text Word] AND osteoarthritis AND pulsed[text Word] on October 8th 2013 Number of hits Results: 38 of which 10 are reviews dated from 1993 till present 1) Efficacy of low frequency pulsed subsensory threshold electrical stimulation vs placebo on pain and physical function in people with knee osteoarthritis: systematic review with meta-analysis. Negm A, Lorbergs A, Macintyre NJ. Osteoarthritis Cartilage. 2013 Sep;21(9):1281-9. doi: 10.1016/j.joca.2013.06.015. Current evidence of low and very low quality suggests that low frequency ( 100 Hz) pulsed subsensory threshold electrical stimulation produced either through PEMF/PES vs sham PEMF/PES is effective in improving physical function but not pain intensity at treatment completion in adults with knee OA blinded to treatment. Methodologically rigorous and adequately powered RCTs are needed to confirm the findings of this review. 1) Effekten af lavfrekvent pulserende subsensory tærskel elektrisk stimulation vs placebo på smerte og fysisk funktion hos personer med knæartrose: systematisk gennemgang med meta-analyse. Negm A, Lorbergs A, Macintyre NJ. Slidgigt Brusk. 2013 Sep; 21 (9) :1281-9. doi: 10.1016/j.joca.2013.06.015. Nuværende beviser for lav og meget lav kvalitet tyder på, at lav frekvens ( 100 Hz) pulset subsensory tærskel elektrisk stimulation produceret enten via PEMF / PSE vs humbug PEMF / PES er effektiv til at forbedre den fysiske funktion, men ikke smerte intensitet ved behandlingen er afsluttet hos voksne med knæet OA blindet for behandlingen. Metodisk strenge og tilstrækkeligt drevne RCTs er nødvendige for at bekræfte resultaterne af denne gennemgang. Effect of pulsed electromagnetic fields on the bioactivity of human osteo-arthritic chondrocytes. Sadoghi P, Leithner A, Dorotka R, Vavken P. Orthopedics. 2013 Mar;36(3):e360-5. doi: 10.3928/01477447-20130222-27.
2) The authors concluded that low-frequency PEMFs do not significantly influence the biosynthetic activity of explantcultures of human osteoarthritic cells in vitro. Never-theless, they may be suitable as an adjuvant to a larger treatment regimen. Effekt af pulserende elektromagnetiske felter på bioaktivitet af humane osteo-gigt chondrocytter. Sadoghi P, Leithner A, Dorotka R Vavken P. ortopædi. 2013 Mar; 36 (3): e360-5. doi: 10.3928/01477447-20130222-27. Konklusion: Forfatterne konkluderede, at lavfrekvente PEMFs ikke væsentligt påvirker den biosyntetiske aktivitet explantcultures af humane osteoartrotiske celler in vitro. Ikke desto mindre kan de være egnede som en adjuvans til et større behandlingsregime. 3) [Pulsed electromagnetic field therapy for the treatment of knee osteoar-thritis: a systematic review]. Cao LY, Jiang MJ, Yang SP, Zhao L, Wang JM. Zhongguo Gu Shang. 2012 May;25(5):384-8. Review. Chinese. Five RCTs totaling 331 patients were included. The results showed that compared with placebo control treatment, pulsed electromagnetic field therapy had little clinical benefit. The effects of Pulsed electromagnetic field therapy for treating knee osteoarthritis need more powerful trials to be confirmed. The above conclusions still need more high-quality randomized controlled trials to be verified owing to the limitations of the number and the quality of systematic review included studies. Fem RCTs alt 331 patienter blev inkluderet. Resultaterne viste, at sammenlignet med placebo kontrolbehandling, pulserende elektromagnetisk felt terapi havde lidt klinisk fordel. Virkningerne af Pulserende elektromagnetisk felt terapi til behandling af knæ slidgigt har brug for mere kraftfulde forsøg, der skal bekræftes. Ovenstående konklusioner stadig brug for flere høj kvalitet randomiserede kontrollerede forsøg, der skal kontrolleres på grund af de begrænsninger i antallet og kvaliteten af de systematiske anmeldelse inkluderede studier. 4) Effects of pulsed electromagnetic field on knee osteoarthritis: a system-atic review. Ryang We S, Koog YH, Jeong KI, Wi H. Rheumatology (Oxford). 2013 May;52(5):815-24. doi: 10.1093/rheumatology/kes063. Epub 2012 Apr 13. Review. The present study provided suggestive evidence supporting PEMF efficacy in the management of knee OA. Our results further raise the need for more well-controlled trials, employing adequate methodology, to conclusively evaluate the efficacy of PEMF Nærværende undersøgelse gav suggestive beviser til støtte for PEMF effekt i forvaltningen af knæet OA. Vores resultater yderligere at øge behovet for mere velkontrollerede forsøg, som beskæftiger tilstrækkelig metode til endegyldigt evaluere effekten af PEMF 5) Non-invasive electromagnetic field therapy produces rapid and substantial pain reduction in early knee osteoarthritis: a randomized double-blind pilot study. Nelson FR, Zvirbulis R, Pilla AA. Rheumatol Int. 2013 Aug;33(8):2169-73. doi: 10.1007/s00296-012-2366-8. Epub 2012 Mar 27.
The overall decrease in mean VAS score for the active cohort was nearly threefold that of the sham cohort (P < 0.001). The results suggest that non-thermal, non-invasive PEMF therapy can have a significant and rapid impact on pain from early knee OA and that larger clinical trials are warranted. Det samlede fald i den gennemsnitlige VAS score for den aktive kohorten var næsten tredoblet, at den fingeret kohorten (P <0,001). Resultaterne tyder på, at ikke-termisk, noninvasive PEMF terapi kan have en betydelig og hurtig effekt på smerter fra tidlig knæ OA, og at større kliniske forsøg er berettiget. 6) Chondroprotective effects of pulsed electromagnetic fields on human car-tilage explants. Ongaro A, Pellati A, Masieri FF, Caruso A, Setti S, Cadossi R, Biscione R, Massari L, Fini M, De Mattei M. Bioelectromagnetics. 2011 Oct;32(7):543-51. doi: 10.1002/bem.20663. Epub 2011 Mar 15. PEMF and IGF-I augment cartilage explant anabolic activities, increase PG synthe-sis, and counteract the catabolic activity of IL-1β in OA grades I and III. We hypoth-esize that both IGF-I and PEMF have chondroprotective effects on human articular cartilage, particularly in early stages of OA. PEMF og IGF-I forøge brusk eksplantations anabolske aktiviteter, øger PG syntese sis, og modvirke den kataboliske aktiviteten af IL-1β i OA kvaliteter I og III. Vi hypoth-esize at både IGF-I og PEMF har chondrobeskyttende virkninger på menneskers ledbrusk, især i de tidlige stadier af OA. 7) Effects of pulsed electromagnetic fields on cartilage apoptosis signalling pathways in ovariectomised rats. Li S, Luo Q, Huang L, Hu Y, Xia Q, He C. Int Orthop. 2011 Dec;35(12):1875-82. doi: 10.1007/s00264-011-1245-3. Epub 2011 Mar 15. Animal study excluded 8) Comparing different physical factors on serum TNF-α levels, chondrocyte apoptosis, caspase-3 and caspase-8 expression in osteoarthritis of the knee in rabbits.

Animal study excluded 9) Additional effect of pulsed electromagnetic field therapy on knee osteoar-thritis treatment: a randomized, placebo-controlled study. Ozgüçlü E, Cetin A, Cetin M, Calp E. Clin Rheumatol. 2010 Aug;29(8):927-31. doi: 10.1007/s10067-010-1453-z. Epub 2010 May 16. The results of this study show that PEMF does not have additional effect on the classical physical treatment in reducing symptoms of knee OA. Resultaterne af denne undersøgelse viser, at PEMF ikke har yderligere effekt på de klassiske fysiske behandling til at reducere symptomerne på knæ OA.
10). Low frequency pulsed electromagnetic field--a viable alternative therapy for arthritis. Ganesan K, Gengadharan AC, Balachandran C, Manohar BM, Puvana-krishnan R. Indian J Exp Biol. 2009 Dec;47(12):939-48. Review. The analysis of various studies (animal models of arthritis, cell culture systems and clinical trials) reporting the use of PEMF for arthritis cure has conclusively shown that PEMF not only alleviates the pain in the arthritis condition but it also affords chondroprotection, exerts antiinflammatory action and helps in bone remodeling and this could be developed as a viable alternative for arthritis therapy. Analysen af forskellige undersøgelser (dyremodeller af artrit, cellekultur systemer og kliniske forsøg) rapportering brugen af PEMF for gigt kur har endegyldigt vist, at PEMF ikke kun lindrer smerter i gigt tilstand, men det giver også chondroprotection, udøver antiinflammatorisk virkning og hjælper med knogleremodellering og dette kunne udvikles som et levedygtigt alternativ til gigt behandling 11) Effectiveness of pulsed electromagnetic field therapy in the management of osteoarthritis of the knee: a meta-analysis of randomized controlled tri-als. Vavken P, Arrich F, Schuhfried O, Dorotka R. J Rehabil Med. 2009 May;41(6):406-11. doi: 10.2340/16501977-0374. Review. Pulsed electromagnetic fields improve clinical scores and function in patients with osteoarthritis of the knee and should be considered as adjuvant therapies in their management. There is still equipoise of evidence for an effect on pain in the current literature. Pulserende elektromagnetiske felter forbedre de kliniske scoringer og funktion hos patienter med slidgigt i knæ og bør betragtes som adjuverende behandlinger i deres forvaltning. Der er stadig Ligevægt af beviser for en effekt på smerter i den aktuelle litteratur. 12) The effects of pulsed electromagnetic fields in the treatment of knee os-teoarthritis: a randomized, placebo-controlled trial. Ay S, Evcik D. Rheumatol Int. 2009 Apr;29(6):663-6. doi: 10.1007/s00296-008-0754-x. Epub 2008 Nov 18. Applying between-group analysis, we were unable to demonstrate a beneficial symptomatic effect of PEMF in the treatment of knee OA in all patients. Further studies using different types of magnetic devices, treatment protocols and patient populations are warranted to confirm the general efficacy of PEMF therapy in OA and other conditions. Ansøgning mellem grupperne analyse, var vi ikke i stand til at påvise en gavnlig
symptomatisk effekt af PEMF i behandlingen af knæet OA hos alle patienter. Yderligere undersøgelser ved hjælp af forskellige typer af magnetiske enheder, behandlingsprotokoller og patientgrupper er berettiget til at bekræfte den generelle effekt af PEMF terapi i OA og andre betingelser. 13) Effects of pulsed and sinusoid electromagnetic fields on human chondro-cytes cultivated in a collagen matrix. Schmidt-Rohlfing B, Silny J, Woodruff S, Gavenis K. Rheumatol Int. 2008 Aug;28(10):971-7. doi: 10.1007/s00296-008-0565-0. Epub 2008 Apr 4. In conclusion, using our in vitro setting, we were unable to detect any effects of pulsed and sinusoidal magnetic fields on human adult osteoarthritic chondrocytes. Konklusionen er, ved hjælp af vores in vitro indstilling var vi i stand til at opdage eventuelle effekter af pulserende og sinusformet magnetiske felter på humane voksne osteoarthritic chondrocytter. 14) Pulsed electromagnetic fields (PEMF)--results in evidence based medi-cine]. Pieber K, Schuhfried O, Fialka-Moser V. Wien Med Wochenschr. 2007 Jan;157(1-2):34-6. Review. German. Therapy with electromagnetic fields has a very old tradition in medicine. The indica-tions are widespread, whereas little is known about the effects. Controlled randomiz-ied studies with positive results for pulsed electromagnetic fields (PEMF) are availa-ble for osteotomies, the healing of skin wounds, and osteoarthritis. Comparison of the studies is difficult because of the different doses applied and intervals of thera-py. Therefore recommendations regarding an optimal dosis and interval are, de-pending on the disease, quite variable. Terapi med elektromagnetiske felter har en meget gammel tradition i medicin. De indikationer er udbredt, mens lidt om effekterne. Kontrollerede randomiz-ied undersøgelser med positive resultater for pulserende elektromagnetiske felter (PEMF), er til-gængelig for osteotomier, heling af huden sår, og slidgigt. Sammenligning af studierne er vanskelig på grund af de forskellige anvendte doser og intervaller af tera-py. Derfor anbefalinger vedrørende en optimal dosis og interval er af-hængig af sygdommen, ganske variabel. 15) Effects of pulsed electromagnetic fields on patients' recovery after arthro-scopic surgery: prospective, randomized and double-blind study.
Zorzi C, Dall'Oca C, Cadossi R, Setti S. Knee Surg Sports Traumatol Arthrosc. 2007 Jul;15(7):830-4. Epub 2007 Feb 28. At 3 years follow-up, the number of patients who completely recovered was higher in the active group compared to the control group (P < 0.05). Treatment with I-ONE aided patient recovery after arthroscopic surgery, reduced the use of NSAIDs, and also had a positive long-term effect. Efter 3 år opfølgning, var antallet af patienter, der fuldstændigt inddrevet højere i den aktive gruppe sammenlignet med kontrolgruppen (p <0,05). Behandling med I-ONE hjulpet patient bedring efter artroskopisk kirurgi, reduceret brug af NSAID, og havde også en positiv langsigtet effekt. 16) Biophysical stimulation with pulsed electromagnetic fields in osteonecro-sis of the femoral head. Massari L, Fini M, Cadossi R, Setti S, Traina GC. J Bone Joint Surg Am. 2006 Nov;88 Suppl 3:56-60. - OBS Osteonecrosis The results of this study confirm that pulsed electromagnetic field treatment may be indicated in the early stages of osteonecrosis of the femoral head (Ficat stages I and II). Pulsed electromagnetic field stimulation may be able to either preserve the hip or delay the time until surgery. The authors hypothesize that the shortterm ef-fect of pulsed electromagnetic field stimulation may be to protect the articular carti-6 af 9 lage from the catabolic effect of inflammation and subchondral bone-marrow edema. The long-term effect of pulsed electromagnetic field stimulation may be to promote osteogenic activity at the necrotic area and prevent trabecular fracture and sub-chondral bone collapse. Konklusion: - OBS Osteonekrose Resultaterne af denne undersøgelse bekræfter, at pulserende elektromagnetisk felt behandling kan være indiceret i de tidlige stadier af osteonekrose af lårbenshovedet (Ficat fase I og II). Pulserende elektromagnetiske felt stimulation kan være i stand til enten at bevare hoften eller forsinke tiden indtil operationen. Forfatterne hypotesen, at på kort sigt effekten af pulserende elektromagnetisk felt stimulation kan være at beskytte artikulaer Carti-6 af 9 Lage fra kataboliske virkning af inflammation og subchondral knogle-marv ødem. Den langsigtede effekt af pulserende elektromagnetisk felt stimulation kan være at fremme osteogen aktivitet på nekrotiske området og forhindre trabeculær fraktur og sub-chondral knogle sammenbrud. 17) Pulsed electromagnetic energy treatment offers no clinical benefit in reduc-ing the pain of knee osteoarthritis: a systematic review. McCarthy CJ, Callaghan MJ, Oldham JA. BMC Musculoskelet Disord. 2006 Jun 15;7:51. Review.
This systematic review provides further evidence that PEMF has little value in the management of knee osteoarthritis. There appears to be clear evidence for the rec-ommendation that PEMF does not significantly reduce the pain of knee osteoarthri-tis. Denne systematiske gennemgang giver yderligere beviser for, at PEMF har ringe værdi i forvaltningen af knæet slidgigt. Der synes at være klare beviser for anbefaling, at PEMF ikke reducere smerten ved knæet osteoarthri-tis. 18) Effects of pulsed electromagnetic fields on articular hyaline cartilage: re-view of experimental and clinical studies. Fini M, Giavaresi G, Carpi A, Nicolini A, Setti S, Giardino R. Biomed Pharmacother. 2005 Aug;59(7):388-94. Review. Therefore, there is a strong rationale supporting the in vivo use of biophysical stimu-lation with PEMFs for the treatment of OA. In the present paper some recent exper-imental in vitro and in vivo data on the effect of PEMFs on articular cartilage were reviewed. These data strongly support the clinical use of PEMFs in OA patients. Derfor er der et stærkt rationale understøtter in vivo anvendelse af biofysisk stimule-ning med PEMFs til behandling af OA. I nærværende dokument nogle nylige eksper-imental in vitro og in vivo data om effekten af PEMFs på ledbrusk blev gennemgået. Disse data støtter stærkt den kliniske anvendelse af PEMFs i OA patienter 19) The effect of pulsed electromagnetic fields in the treatment of cervical os-teoarthritis: a randomized, double-blind, sham-controlled trial. Sutbeyaz ST, Sezer N, Koseoglu BF. Rheumatol Int. 2006 Feb;26(4):320-4. Epub 2005 Jun 29. The results of this study are promising, in that PEMF treatment may offer a potential therapeutic adjunct to current COA therapies in the future. Resultaterne af denne undersøgelse er lovende, idet PEMF behandling kan tilbyde en potentiel terapeutisk supplement til de nuværende COA behandlinger i fremtiden. 20) Treatment of knee osteoarthritis with pulsed electromagnetic fields: a randomized, doubleblind, placebo-controlled study. Thamsborg G, Florescu A, Oturai P, Fallentin E, Tritsaris K, Dissing S. Osteoarthritis Cartilage. 2005 Jul;13(7):575-81.
Applying between group analysis we were unable to demonstrate a beneficial symp-tomatic effect of PEMF in the treatment of knee OA in all patients. However, in pa-tients <65 years of age there is significant and beneficial effect of treatment related to stiffness. Ansøgning mellem gruppe analyse, vi var ude af stand til at påvise en gavnlig symp-tisk effekt af PEMF i behandlingen af knæet OA hos alle patienter. Men i patienter <65 år er der betydelig og gavnlig effekt af behandlingen forbundet med stivhed 21) A multicenter clinical trial on the use of pulsed electromagnetic fields in the treatment of temporomandibular disorders. Peroz I, Chun YH, Karageorgi G, Schwerin C, Bernhardt O, Roulet JF, Freesmeyer WB, Meyer G, Lange KP. J Prosthet Dent. 2004 Feb;91(2):180-7. Pulsed electromagnetic fields had no specific treatment effects in patients with tem-poromandibular disorders. Pulserende elektromagnetiske felter havde ingen specifikke behandlingseffekter hos patienter med tem-poromandibular lidelser. 22) Modification of osteoarthritis by pulsed electromagnetic field--a morpho-logical study. Ciombor DM, Aaron RK, Wang S, Simon B. Osteoarthritis Cartilage. 2003 Jun;11(6):455-62. Treatment with PEMF appears to be disease-modifying in this model of osteoarthri-tis. Since TGFbeta is believed to upregulate gene expression for aggrecan, down-regulate matrix metalloprotease and IL-1 activity, and upregulate inhibitors of matrix metalloprotease, the stimulation of TGFbeta may be a mechanism through which PEMF favorably affects cartilage homeostasis. Behandling med PEMF synes at være sygdomsmodificerende i denne model af osteoarthri-tis. Da TGFbeta menes at opregulere genekspression for aggrecan nedregulere matrixmetalloprotease og IL-1-aktivitet, og opregulere inhibitorer af matrixmetalloprotease, kan stimuleringen af TGFbeta være en mekanisme, som PEMF positivt påvirker brusk homeostase. 23) Pulsed magnetic field therapy for osteoarthritis of the knee--a double-blind sham-controlled trial. Nicolakis P, Kollmitzer J, Crevenna R, Bittner C, Erdogmus CB, Nicolakis J. Wien Klin Wochenschr. 2002 Aug 30;114(15-16):678-84.
In patients with symptomatic osteoarthritis of the knee, PMF treatment can reduce impairment in activities of daily life and improve knee function. Hos patienter med symptomatisk slidgigt i knæet, kan PMF behandling reducere værdiforringelse i aktiviteter i dagligdagen og forbedre knæ funktion. 24) Nonpharmacologic management of osteoarthritis. Sharma L. Curr Opin Rheumatol. 2002 Sep;14(5):603-7. Review. Several nonpharmacologic interventions for osteoarthritis are in different stages of development, investigation, and application. Such interventions capitalize on current knowledge of the causes of symptoms, disease progression, and disability in pa-tients with osteoarthritis. Many nonpharmacologic interventions are low in cost and incorporate self-management approaches or home-based activities and, as such, may ultimately have substantial public health impact. Recent studies and reviews of exercise, weight loss, education, inserts, footwear, bracing, therapeutic ultrasound, acupuncture, and pulsed electromagnetic field therapy will be highlighted in this re-view. For many of these interventions, further investigation will be necessary to de-fine their place in the management of osteoarthritis. Adskillige nonpharmacologic interventioner for slidgigt er i forskellige stadier af udvikling, efterforskning og anvendelse. Sådanne indgreb kapitalisere på nuværende viden om årsagerne til symptomerne, sygdomsprogression, og handicap i patienter med slidgigt. Mange nonpharmacologic interventioner er lave i pris og indarbejde selvforvaltning tilgange eller hjemme-baserede aktiviteter, og som sådan, kan i sidste ende have en væsentlig indvirkning på folkesundheden. Nylige undersøgelser og anmeldelser af motion, vil vægttab, uddannelse, skær, fodtøj, afstivning, terapeutisk ultralyd, akupunktur og pulserende elektromagnetisk felt terapi blive fremhævet i denne re-view. For mange af disse interventioner, vil yderligere undersøgelser være nødvendigt at de-fine deres plads i forvaltningen af slidgigt. 25) Electromagnetic fields for the treatment of osteoarthritis. Hulme J, Robinson V, DeBie R, Wells G, Judd M, Tugwell P. Cochrane Database Syst Rev. 2002;(1):CD003523. Review. Current evidence suggests that electrical stimulation therapy may provide significant improvements for knee OA, but further studies are required to confirm whether the statistically significant results shown in these trials confer to important benefits. Nuværende tyder på, at elektrisk stimulation terapi kan give betydelige forbedringer for knæ OA, men yderligere undersøgelser er påkrævet for at bekræfte, om de statistisk signifikante resultater er vist i disse forsøg giver til vigtige fordele.
26) Electromagnetic fields and magnets. Investigational treatment for muscu-loskeletal disorders. Trock DH. Rheum Dis Clin North Am. 2000 Feb;26(1):51-62, viii. Review. Certain pulsed electromagnetic fields (PEMF) affect the growth of bone and carti-lage in vitro, with potential application as an arthritis treatment. PEMF stimulation is already a proven remedy for delayed fractures, with potential clinical application for osteoarthritis, osteonecrosis of bone, osteoporosis, and wound healing. Static mag-nets may provide temporary pain relief under certain circumstances. In both cases, the available data is limited. The mechanisms underlying the use of PEMF and magnets are discussed. Visse pulserende elektromagnetiske felter (PEMF) påvirker væksten af knoglen og Cartilage in vitro, med potentielle anvendelse som en arthritis behandling. PEMF stimulation er allerede en gennemprøvet middel til forsinkede brud med potentielle kliniske anvendelse for slidgigt, osteonekrose af knogler, osteoporose og sårheling. Statiske magneter kan yde midlertidig smertelindring under visse omstændigheder. I begge tilfælde er den tilgængelige data begrænset. De mekanismer, der ligger til grund brugen af PEMF og magneter diskuteres 27) The effect of pulsed electromagnetic fields in the treatment of osteoar-thritis of the knee and cervical spine. Report of randomized, double blind, placebo controlled trials. Trock DH, Bollet AJ, Markoll R. J Rheumatol. 1994 Oct;21(10):1903-11. PEMF has therapeutic benefit in painful OA of the knee or cervical spine. PEMF har terapeutisk fordel i smertefulde OA i knæet eller halshvirvelsøjlen. 28) A double-blind trial of the clinical effects of pulsed electromagnetic fields in osteoarthritis. Trock DH, Bollet AJ, Dyer RH Jr, Fielding LP, Miner WK, Markoll R. J Rheumatol. 1993 Mar;20(3):456-60. The decreased pain and improved functional performance of treated patients sug-gests that this configuration of PEMF has potential as an effective method of im-proving symptoms in patients with OA. This method warrants further clinical investi-gation. Den faldt smerte og forbedret funktionsevne behandlede patienter sug-gests at denne konfiguration af PEMF har potentiale som en effektiv metode til im-beviser symptomer hos patienter med OA. Denne metode kræver yderligere kliniske undersøgelse.
