“…Since the finding in 1965 that bone formation is promoted through the reaction of osteoblast under an electromagnetic field [33], pulsed electromagnetic therapy has been applied mainly for the treatment of bone fractures, including nonunion, malunion and delayed union [7,8], , Mann-Whitney U-test; Continuous variables, Independent Two Samples T-test; Categorical variables, Chi-Square test; PEMF, pulsed electromagnetic field; BMI, body mass index; SBP: systolic pressure; DBP, diastolic blood pressure; BT, body temperature; PH, Past History; PMS, premenstrual syndrome; PD, prescription drugs; NPD, non prescription drugs etc. Since approval by the US FDA, it has been applied to diverse treatments.…”

“…[1][2][3]5,7,9,14,20,30 The results have been mixed, with majority of reports describing noticeable effects. The field has progressed to a point where clinical treatment modalities became available using commercial PEMF generators (such as Spinal-Stim Lite TM , Orthofix, McKinney, TX; EBI Bone Healing System R , EBI L.P, Parsippany, NJ; or SpinaLogic R Bone Growth Stimulator, dj Orthopedics Regentek, Tempe, AZ).…”

We studied the PEMF power attenuation in tissues representative of clinical applications (blood and cortical bone) to determine the amount of power available for PEMF purported biological effects. The experimental system consisted of a pair of nearly circular, parallel and coaxial coils separated by a distance of one coil diameter. The power attenuation was measured using a small search coil connected to a digital oscilloscope. The coils were powered by a voltage switch operating at two different frequencies (3.8 and 63 kHz) producing bursts of pulses (numbering 21 and 1619) and triggered at two different frequencies (1.5 and 15 Hz, respectively). The tissue samples were placed inside the coils so as to expose them to either transverse electric field (at the center of coils) or the transverse magnetic field (at the coil wire). The cylindrical coil geometry yielded closed-form expressions for power attenuation based on magnetic diffusion equation and ohmic losses due to bulk tissue magnetic permeability and electrical conductivity. The measured power attenuation at these PEMF frequencies of not more than one decibel (1 dB) was well explained by the theory for the 3.8 kHz but less so for the 63 kHz frequency PEMF. The results provide important insights regarding physical mechanism of weak PEMF power dissipation in tissues.

“…[1] Pulsed electromagnetic fields (PEMFs) have been used as alternative or adjunctive treatment options for different disorders including musculoskeletal disorders, soft tissues, and as bone growth stimulators. [2][3][4][5][6][7][8][9][10] This form of therapy was approved in humans by the United States Food and Drug Administration in 1979, for the treatment of various types of fractures such as delayed and nonunion fractures. [11] The application of external electrical or mechanical energy may affect disorders of dense connective tissue with induces changes to the cell environment.…”

Background and Objective: Pulsed electromagnetic fields (PEMFs) have shown therapeutic outcomes in bone and wound repair and pain and edema reduction. This study was aimed to investigate the effectiveness of PEMFs on post-operative pain in the patients with fresh fracture. Method: This open-label clinical trial was conducted on 20 patients with tibial and femoral fresh fractures. The patients were treated with surgery and received PEMF therapy undergoing a protocol with 20 Hz and 4.25 mT for 4 weeks (20 min daily and 5 consecutive days per week and for 4 consecutive weeks). A visual analog scale was used for recording pain. Results: During the first day of treatment patients had low pain during rest, activity, and nighttime. Each treatment session significantly reduced the mean pain score (P = 0.05). We observed a cumulative pain reduction effect where on day 4 the pain score was significantly reduced compared with day 0 (95.1 ± 2 mm on day 0 to 46.5 ± 3 mm on day 4) (P = 0.001). Furthermore, during the 2 days each week with no treatment session, the pain score increased to the early values. It indicated the temporary effect of PEMF on pain which lasted about 12 h posttreatment. Conclusion: PEMF showed significant clinical value in reducing the pain of post-operative pain in fracture patients. However, it seems that this effect is temporary and does not last more than 24 h after the treatment session.
