Summary

This study evaluates the efficacy isolated and combinaded of photobiomodulation therapy with low level laser therapy and the transcutaneous electrical nerve stimulation.

Detailed description

Non-specific chronic neck pain patients will be treated with low-level laser therapy and/or trancutaneous electricam nerve stimulation. They will receive 10 sessions of treatment. Before and after the treatment physical measures and psychosocial factors will be evaluted to verificy the efficay these electrophysical agents.

Conditions

• Chronic Neck Pain

Interventions

Type	Name	Description
DEVICE	Active PBM	To active photobiomodulation therapy (PBMT) the patient will be oriented to lie preferably in prone. The treatment area will be defined according to painful area. In the active group will be used the followings parameters: low-level laser therapy, 808 nm, 4 infrared diodes, 180 mW, 9 J. In the placebo PBMT will be performed a simulation of laser application. The cluster probe will be positioned on painful area during the same time of active PBMT, the equipment will be turned on and set, however the trigger will be not actived and no beam will be applied.
DEVICE	Active TENS	To active transcutaneous electrical nerve stimulation (TENS) the patient will be oriented to lie preferably in prone. Two or four electrodes standard square self-adhesive electrodes (5 × 5 cm2) will be positioned according to the painful area related by patient. It will be used the following parameters: frequency of 100 Hz, pulse duration of 125 µs (positive phase), 30 minutes of current stimulation and the pulse amplitude will be increased until the patient reports a strong but comfortable paresthesia (including motor level stimulation but no painful TENS). The amplitude will be adjusted (if necessary) each 5 minutes to keep a strong but comfortable paresthesia.
DEVICE	Placebo PBM	In the placebo PBMT will be performed a simulation of laser application. The cluster probe will be positioned on painful area during the same time of active PBMT, the equipment will be turned on and set, however the trigger will be not actived and no beam will be applied.
DEVICE	Placebo TENS	To placebo transcutaneous electrical nerve stimulation (TENS) Two or four electrodes standard square self-adhesive electrodes (5 × 5 cm2) will be positioned according to the painful area related by patient. This device was customized to deliver a current for 30 seconds (both channels) and then ramp off over the next 15 seconds so that it will be active for a total of 45 seconds. This will permit the patient to fell the TENS sensation while applying the settings.
