General Guidelines Ensure that treatment is not contraindicated (see manual) and that eye protection is worn. This treatment is to 'block' pain through reducing nerve conduction - see specific conditions for healing guidance. The 5 diode 820nm laser cluster is helpful in reducing time for this application. Application Guidelines 820nm: Treat across nerve roots at points 1cm apart at the settings below: Follow up with Multi-Wavelength cluster to cover the treated area at the settings below: Probe Time per Point Dose per Point Pulse Range 820nm 200mW 1 minute 96 J/cm2 1 kHz 60 (or 20) Diode MW Cluster 1 minute 6 J/cm2 20 - 73 - 146 Hz Frequency of Treatment At least once a week, not more than daily.
