Clinically, latent myofascial trigger points are characterized as hyperirritable points located within taut bands of skeletal muscles or fascia. These points may cause referred pain, local tenderness and autonomic changes when manually stimulated. Dry needling is one of the treatment options but evidence of its results is scarce. This paper experimentally investigates the potential use of thermal imaging to assess the effect of dry needling on the skin temperature in patients with latent myofascial trigger points. No significant differences were found between the mean skin temperature and pain before and after the treatment, evidencing the agreement between the outcome measures.
