Efficiency Of High Power Laser Versus Pulsed Electromagnetic Therapy On Hemiplegic Shoulder Pain

The MLS® Laser Therapy device used in this study is M6 (ASA srl -Arcugnano, Italy), equipped with both a robotized multidiode head (up to 3,3W), able to perform automatic scanning treatments, and an MLS® handpiece (up to 1,1W), aimed to perform manual point to point or scanning treatments. Each treatment includes two stages: the scanning of the frontal and dorsal shoulder area of 93 cm2 each with a robotized multidiode head and a point-by-point process with the manual handpiece with 7 points of 3,14 cm2 area.

the PEMF application, with application of low intensity and frequency pulsed electromagnetic fields (PEMF), the portable device PMT QS (ASA Srl, Arcugnano) is used, equipped with Flexa applicators (36 x 21 x 2 cm (L x P x H) - 1.2 kg), programmable frequency from 0.5 to 100 Hz and variable magnetic field intensity from 5% to 100% (from \~2.5 to \~40 Gauss)), two solenoid applicators are placed at the anterior and posterior positions in the patient's shoulders and applied for 25 min at 25 G intensity at a frequency of 50 Hz.

The conventional exercise program for hemiplegic shoulder pain (HSP) is stretching exercise therapy, joint stabilization exercise therapy.
