Carpal tunnel syndrome: current theory, treatment, and the use of B6.

PURPOSE: To present the current state of the science of pathophysiology, assessment and treatment of carpal tunnel syndrome, including the use of pyridoxine (B6).

DATA SOURCES: Selected research articles, texts, Websites, personal communications with experts, and the authors' own clinical experience.

CONCLUSIONS

Much is yet to be learned about carpal tunnel syndrome. While the basic treatment of NSAIDs and nighttime splints seems universally accepted, much controversy remains. The use of vitamin B6 as a treatment is one such controversy requiring further investigation.

IMPLICATIONS FOR PRACTICE: Current treatment for carpal tunnel syndrome should include NSAIDs, nighttime splinting, ergonomic workstation review, and vitamin B6 200 mg per day.
