Laser acupuncture therapy might be a feasible treatment for chronic Bell's palsy and its long-term complications according to this pilot study.
Randomised Controlled Trial Laser Acupuncture
Methodology: This study was a two-armed, parallel, randomized, investigator-subject-assessor-blinded, sham-controlled pilot study with 17 deserving participants who were randomly assigned to either Laser Acupuncture Therapy (LAT) or sham LAT group. The LAT group had three sessions of therapy every week for a period of six weeks, receiving a total of 18 sessions, while the sham LAT group underwent the same procedure but with a sham laser device. The change in the social subscale of the Facial Disability Index from the start to the end (week 6) was used as the primary outcome measurement. Additional outcomes measured included changes in the House-Brackmann facial paralysis scale, Sunnybrook facial grading system, and stiffness scale at weeks 3 and 6.
Discussion of Results: The House-Brackmann score demonstrated a notable difference between the start of the study and the third week, and the Sunnybrook and stiffness scores showed borderline significance from the onset to the conclusion (week 6). However, comparison between the Facial Disability Index score at the start and end of six weeks did not yield any considerable difference. These findings suggested that LAT may have clinical effects on chronic Bell's palsy and its long-term complications.
