Musculoskeletal Disorders | Acute Effect of Topical Menthol on Neck Pain

Musculoskeletal Disorders research study

What is the primary objective of this study?

Topical menthol gels are classified 'topical analgesics' and are used to relieve aching and tenderness of muscles and joints. However, double-blind randomized controlled trials are lacking. Here the investigators examine - in a double-blind randomized controlled cross-over trial - the acute effect of topical menthol (Biofreeze) and placebo (gel with a menthol scent) on neck pain.

Who is eligible to participate?

Inclusion Criteria: - more than 30 days with neck pain during the last year - frequent pain or discomfort, defined as at least 3 days per week - pain intensity at least 4 on a scale of 0-10 - working at least 30 hours per week Exclusion Criteria: - blood pressure above 160/100 mmHg - pregnancy - life-threatening disease
