PEMF therapy is getting popular in clinical settings as physical therapy for promoting bone health through hard and soft tissue regeneration. The pulsed fields come with certain signal wave shapes of low frequencies, normally ranging from 5 to 100 hertz.
How Does It Work?
The overall influence of the applied PEMF helps to regulate different biological functions. For example, on the cellular level, healthy cell membranes come with polarized magnetic charges. The charges are important for the ion exchange carrying different elements through the cells. If the cells become damaged or deteriorate, they will experience a decrease in the electromagnetic charge, and therefore a decreased ability to exchange different ions. PEMF therapy also assists in restoring the cellular charge, improving the overall production of cellular energy.
What’s more, it also aids in healing the hiatuses of the upper limbs. Furthermore, science vividly acknowledges the effectiveness of PEMF therapy to relieve chronic bone pain with no side effects. Some research also indicates that PEMF is able to accelerate the overall soft tissue injury healing, for example, hematomas, contusion, luxation, and sprain up to 50%.
In medical settings, around four to a total of eight PEMF sessions help in treating acute and subacute medical conditions. For chronic conditions, the session number ranges from 10 to 15. The high frequency promotes damaged bone tissue healing in patients having algo-neurodystrophy.
What Do Studies Suggest?
In one study, high-frequency PEMF therapy helped accelerate the overall healing of fractures in rats by improving the overall rate of the mineralization of callus. Especially, the BV to TV ratio at around the second and eighth-week post-op was high compared to the control group. Also, the concentration of the osteogenic markers as well as the early ALP markers was high as well. What’s more, the overall mechanical strength test was better than the control group.
What’s more, the mechanical strength test resulted in high bending strength and reduced elastic femur deformation in the PEMF group. What’s more, the results indicate an advanced bone healing stage in PEMF in comparison to the control group at both second and eighth weeks postoperatively.
Factors to Consider for Bone and Soft Tissue Healing
Some studies show the optimum frequency range of the PEMF for human subjects to be between 1 to 50 hertz. It was also understood in studies that frequencies above 100 hertz are not effective. In PEMF therapy, longer intervals getting between the pulses may eliminate any heat produced, which results in a non-thermal biological effect. What’s more, the overall impulse frequency has been calculated, so the impulse effect continues to have a biological influence on the preceding impulse.
Some evidence in traumatology and orthopedics also shows PEMF therapy to be effective in decreasing edema, pain reduction, and wound recovery time. It also helps in resolving hematoma as well as bone consolidation. It is well-acknowledged that controlled micromovements stimulate callus formation when applied to the focal point of the fracture.
The patient is not able to move and is immobilized to get moving in some days after trauma. The direct electric current application, as well as the associated field of electromagnetic waves at the focal point of fracture, mimics mechanical stress to the bone. It, in return, helps to promote new bone formation and mineralization.
What’s more, PEMF exposure duration is a factor to not ignore, especially when it comes to patient compliance. In a traditional clinical setting having a PEMF facility, the professional places the transmitter at a very low distance from the body, as the layer of air between the region emitting PEMF and the body surface results in the dispersion of the electromagnetic waves.
The overall use of electrical stimulation is helpful to resolve different non-union bone fractures that go impaired. For more information on PEMF therapy and equipment, visit HealthylineOutlet.com.
