Photobiology

Interventions
Procedure: Laminectomy
Device: Spinal nerve laser therapeutic apparatus(Composed of 808-band fully automatic control laser device and implantable 360° scattering medical fiber)
Registration Number
NCT03643419

Xijing Hospital
Brief Summary

The purpose of this study was to observe the therapeutic effect of near-infrared light irradiation on the treatment of acute spinal cord injury in humans, and whether it can promote the recovery of neurological function. Half of the patients underwent laminectomy and decompression surgery, and the other half of the patients were implanted with irradiated fibers for irradiation after surgery.

Detailed Description

The annual incidence of spinal cord injury has increased year by year, and there is currently no effective treatment.

Near-infrared light has been widely used in clinical medicine because of its bio-stimulating effect, convenient use, harmless to the body, easy to be accepted by patients, and convenient for clinical promotion. The near-infrared light biostimulation effect can enhance the activity of various enzymes, inhibit inflammatory cells, inhibit neuronal apoptosis, and promote nerve regeneration. It has been widely confirmed and widely used in the rehabilitation of central nervous system and peripheral nerve injury. However, the position of the spinal cord is deep, and the depth of illumination used by laser treatment equipment is generally difficult to reach.

The implantable 360° scattering fiber the investigators developed was implanted in the surgical site together with the drainage tube for irradiation treatment without additional patient damage.

Primary Outcome Measures
NameTimeMethod
Change from Baseline ASIA Rating Scale at 6 Months6 Months

The ASIA rating scale was used to evaluate the patient's function, and the scores of each major item were obtained according to the weighting factors of each major item, with a total score of 0 to 100 points.

Change from Baseline ASIA Rating Scale at 12 Months12 Months

The ASIA rating scale was used to evaluate the patient's function, and the scores of each major item were obtained according to the weighting factors of each major item, with a total score of 0 to 100 points.

Change from Baseline EMG at 6 Months6 Months

The motor evoked potentials(MEP) and sensory evoked potentials(SEP) were evaluated, and the differences in the latency of the evoked potential N1 wave between the two groups were compared.
