Effect of Pulsed Electromagnetic Filed versus Low Level Laser in Modulation of Knee Hemoarthrosis, ALAA R. MORGAN
Abstract
Background: Electromagnetic field and low level laser therapy have effect in treating knee hemoarthrosis of hemo-philic children as they plays an important role in decreasing swelling and improving muscle power of the knee joint.
Aim of this Study: To investigate the effect of pulsed electromagnetic field versus low level laser in modulation of knee hemoarthrosis in hemophilic children (after successive three months of treatment).
Patients and Methods: Forty hemophilic children their age ranging from seven to fourteen years, divided randomly into two groups (Group A and Group B). Group A received pulsed electromagnetic field and selected physical therapy program (therapeutic ultrasound, stretching, and strengthening exercises) three times per week for three months, while the Group B received low level laser therapy in addition to the same program given to the Group A. The peak torque param-eter (biodex isokinetic dynamometer) was measured before and after the treatment.
Results: The study revealed significant improvement in most of the measured variables of the two groups, without significant improvement in one group more than the other one. Conclusion: It may conclude that pulsed electromagnetic field and low level laser therapy have the same effect in treating knee hemoarthrosis of hemophilic children as they plays an important role in decreasing swelling and improving muscle power of the knee joint.
