Patients and therapists are not aware of the type of study group, Blinding description: Patients and therapists are not aware of the type of study group. N/A acute renal impairment. Intervention 1: Intervention group: Patients underwent intravenous laser radiation using infrared radiation. This method is non-thermal and non-toxic, using a continuous infrared beam or near infrared 600 nm with a power output of 5 mW. In this method, the laser light directly irradiates through a sterile disposable catheter. Two millimeters of optical fiber (200 nm in diameter and silicon dioxide) enter the vein and circulate in the circulation. This procedure is just like the injection of serum. Intravenous light red light, in this study with a power of 5 mW for 30 minutes. The intravenous laser is performed for 7 sessions per day. Intervention 2: Control group: Under Sham Laser. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is Not enough time
