Case in brief
Two patients with chronic Bell’s palsy received non-invasive laser acupuncture three times weekly. Assessment included facial nerve grading scales, electromyography, electroneurography, and blink reflex testing. Both patients reported sensations that propagated along meridian pathways during treatment, and both showed clinical improvement afterward. The report describes these sensations alongside the clinical outcomes but does not establish whether they were related.
What made this case unusual
The notable finding was patient-reported propagation of sensation along meridian pathways during non-invasive laser acupuncture for facial paralysis.
Diagnostic / clinical pearl
In this report, propagated meridian sensations occurred during laser acupuncture in patients with chronic Bell’s palsy; their relationship to clinical improvement remains undetermined.
Why it matters
The authors identify the need for further study of the relationship between these sensations and outcomes, as well as their underlying mechanisms.
