Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The majority of HSP develop in the first 2 weeks up to 6 months and about 65% of those will continue to experience the problem several months after that .
The actual cause of HSP is uncertain and frequently complex. So far, numerous pathogenic processes have been found that are likely to be associated to HSP: Joint subluxation, adhesive capsulitis, complex regional pain syndrome, rotator cuff injury, spasticity, and other conditions .
In the last few decades, an enormous number of treatment options have been developed due to the multiple etiology of HSP, But there is still a great deal of uncertainty regarding their efficacy because several etiologies probably lead to the same problem .
High power laser therapy is one suggested therapeutic option for shoulder pain HPLT has long been used to treat conditions that low power laser therapy (LPLT) cannot, such as increased microcirculation, accelerated tissue regeneration, decreased swelling, inflammation, and pain, because of its photomechanical, thermal, electrical and bio stimulating effects on deep tissues. Benefits of HPLT over LPLT include higher power, deeper tissue penetration, shorter emission durations, and longer rest intervals that avoid heat buildup.
It is hypothesized that compared to single-wavelength low-level laser therapy (LLLT), Multiwave Locked System (MLS) allows for better penetration and therapeutic efficacy .
Magnetic field therapy enhances local cellular activity, organizes collagen fibers, enhances oxygen use in tissues, and speeds up circulation by enhancing blood vessel vasodilation without raising local temperatures but There is insufficient evidence supporting its efficacy and superiority to physical therapy agents .
To our knowledge this is the first study to determine the efficiency of high-power laser and pulsed electromagnetic field on hemiplegic shoulder pain.

INTERVENTION 1 LASER
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. 3 sessions per week for 4 weeks
