Spinal cord injury (SCI) signifies a serious form of trauma in central nervous system, and most occasions have reasons that involve incidents like vehicle accidents, attacks, athletics, or falls. Clinical characteristics of SCI consist of a complete/ incomplete deficit of perception right away beneath the level of injury, including sensory/motor dysfunction and autonomic impairment, for examples, numb-tingling, loss of touch function, muscular weakness/paralysis, urinary/feces disorder. Lesions in the neck region produce tetraplegia.

A 68-year-old male with SCI, C3, incomplete, participated in the study, who experienced sudden onset muscle paralysis in four limbs and a diagnosis of acute C3 spinal cord injury was made. He visited our hospital for advanced recovery and regaining independent mobility. The intervention comprised iLIB combined with physical therapy and occupational therapy. Physical therapy programs included facilitation techniques for four limbs, weight-bearing mat exercises, Bed mobility training, upper limb strengthening. Five months after the onset of symptoms, the patient could walk independently with a walker but was still unable to urinate without difficulty. A laser device illuminator as output by “Liverage” (Multiwavelength Laser treatment instrument SL-1200, LIVERAGE BIOMEDICAL INC., Taiwan) was provided, which contains two wavelengths of 415 nm (blue-light) and of 650 nm (red-light). The intensity is 3-5mW with Energy density = 22.86 J/ cm2 for both colors of light with total irradiation time of 60 min/session with each half of the time He finished the iLIB for three courses (1 hour each session for 10 consecutive days each course, with a rest interval of 7-21 days). Following three courses of iLIB, outcome measurements improved. The overall neurologic level of injury improved from C3 to C4. Most notably, functional gains persisted for over 4-month follow-up without further treatment.

Compared with other cases of high cervical spinal cord injury, our case showed better clinical outcomes after proper rehabilitation programs, including physical therapy and occupational therapy, and iLIB. One of the key parts of the recovery process for the case is iLIB.
