Other factors involved in responses to mechanical stimuli

Electromagnetic fields

Bending and stretching of bone creates electrical fields thought to originate from the apatite crystals (piezoelectricity) (Fig. i.8.3). Electromagnetic fields generated during mechanical stimulation show distinct effects on bone. As mentioned above they reduce osteoclastic recruitment and increase osteoblastic bone formation. The response is highly frequency dependent, with frequencies below 75 Hz being most effective [24]. Magnetic field exposure inhibits cell growth through a mechanism independent of gap junctional coupling, while the alteration in alkaline phosphatase (AP) activity appears to be stimulated by electric fields independent of gap junctions [25].

Osteoarthritis

Thank you for deciding to learn more about the disorder, Osteoarthritis. Inside these pages, you will learn what it is, who is most at risk for developing it, what causes it, and some treatment plans to help those that do have it feel better. While there is no definitive “cure” for Osteoarthritis, there are ways in which individuals can improve their quality of life and change the discomfort level to one that can be tolerated on a daily basis.
