PULSING AND FREQUENCIES
THERAPY LASERS CAN PULSE IN DIFFERENT WAYS Generally speaking, therapy lasers that pulse either operate in a superpulsed mode or gated mode. In superpulsed mode, a large amount of energy is allowed to build up over a period of time, and then released quickly in a single, large burst of energy. Superpulsed lasers produce very brief pulses (on the order of 200 nanoseconds) of high frequency. The pulses have high peak powers (up to 3000W) with a much lower average power (such as 60 mW).
PHOTOBIOMODULATION THERAPY CAN BE DELIVERED IN EITHER CONTINUOUS WAVE (CW) OR PULSED MODES As photobiomodulation therapy has become more popular, manufacturers have made elaborate claims about specific pulsing protocols and application-specific wavelengths. These claims can be misleading and can create confusion. In reality these product-specific bells and whistles are more marketing hype than science. A review by Hashmi et al. that looked at CW versus pulsed light concluded that more evidence is needed. 9 In general, the use of pulsing decreases light delivered to the surface and hence to the target.
FREE WEBINAR: SUPER CONFUSED ABOUT SUPER PULSING?
If you’re super confused about the role super pulsing plays in laser therapy, you’re not alone! In this webinar, Mark Callanen, PT, DPT, OCS will clear up the misconceptions about this abundantly used marketing term. He will address the impact that pulsing and super pulsing have on the key laser therapy treatment principles responsible for clinical successes - and failures.
