Effect of Pulsed Electromagnetic Fields on Clinical Signs and Quality of Life in Patients with Hemophilic Arthropathy of the Knee Joint: A Randomized Controlled Trial.

Background: Hemophilic arthropathy (HA) causes severe joint damage and impairs the quality of life (QoL) of hemophiliacs. This study was undertaken to evaluate the effect of pulsed electromagnetic fields (PEMFs) on the clinical signs and QoL of patients with severe hemophilia A experiencing moderate HA in the knee joint.

Materials And Methods: Thirty-six severe hemophiliacs with HA of the knee joint were randomly assigned into the PEMF ( = 20) or placebo ( = 16) groups.
