简介
OBJECTIVE
To assess the effect of carrier frequency of interferential current (IFC) on pressure pain threshold (PPT) and sensory comfort in healthy subjects.
DESIGN
A double-blind randomized trial.
SETTING
University research laboratory.
PARTICIPANTS
Healthy subjects (N=150).
INTERVENTIONS
Application of the IFC for 20 minutes and measures of PPT collected in the regions of the nondominant hand and forearm.
MAIN OUTCOMES MEASURES
We measured PPT and comfort at frequencies of 1kHz, 2kHz, 4kHz, 8kHz, and 10kHz.
RESULTS
There was a significant increase in PPT in the 1-kHz group when compared with the 8-kHz and 10-kHz groups. There was a greater discomfort in the 1-kHz and 2-kHz groups.
CONCLUSIONS
IFC with a carrier frequency of 1kHz promotes a higher hypoalgesic response during and after stimulation than IFC with carrier frequencies of 8kHz and 10kHz. Carrier …
