Brief summary

This study investigate the potential impact of low power laser (LPL), an non-invasive physical therapy, on the cardiovascular system by focusing on its effect on heart rate and autonomic tone. Study will recruit healthy volunteers and non-invasively monitor their electrocardiogram and digital pulse in response to LPL. In addition, the potential involvement of autonomic tone will be clarify by topically applying gel (2% lidocaine gel)

Detailed description

This study investigate the potential impact of low power laser (LPL), an non-invasive physical therapy, on the cardiovascular system by focusing on its effect on heart rate and autonomic tone. Study will recruit healthy volunteers (age 20-60; having no diabetes, hypertension, or other medical problem) and non-invasively monitor their electrocardiogram and digital pulse in response to LPL (with an intensity for relieving pain). In addition, the potential involvement of autonomic tone will be clarify by topically applying gel (2% lidocaine gel) at the site 2 cm distal to the applying site.
