Effects of intravascular photobiomodulation on motor deficits and brain perfusion images in intractable myasthenia gravis: A case report

Table 1 Myasthenia gravis activities of daily living scale

MG-ADL scale	Before ILIB intervention	After ILIB intervention
Talking	1	0
Chewing	1	0
Swallowing	2	1
Breathing	2	0

The effect of intravascular laser irradiation of blood was assessed using the myasthenia gravis activities of daily living scale for the following eight criteria: talking, chewing, swallowing, breathing, brushing teeth or combing hair, rising from a chair, double vision, and eyelid droop. The numbers in the table represent grades from the maximum of 3 to the minimum of 0. MG-ADL: Myasthenia gravis activities of daily living; ILIB: Intravascular laser irradiation of blood.

The effect of intravascular laser irradiation of blood was measured based on 13 criteria from the quantitative myasthenia gravis scale. The numbers in the table represent grades from the maximum of 3 to the minimum of 0. MG: Myasthenia gravis; ILIB: Intravascular laser irradiation of blood.
