Interventions
The subjects were randomly divided into five groups, described as follows:
Adjusted motor group: 25 participants of both sexes were recruited, the interferential current (IFC) was applied for 30 minut
at intervals of 5 minutes, the intensity was increased again until a strong sensation.
Fixed motor group: 25 participants of both sexes were recruited, the IFC was applied for 30 minutes at a frequenc
this intensity was maintained at this level throughout the procedure.
Sensory group: 25 participants of both sexes were recruited, the IFC was applied for 30 minutes at a frequency of 100Hz, the inten
the subjects were connected to the device for 30 minutes.
New placebo group: 25 participants of both sexes were recruited, an external device, manufactured exclusively for this study, was connected to
the subjects were connected to the device for 30 minutes.
In all groups, the electrodes were placed on the subject's forearm.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Over 50% of subjects, included in the new placebo group, respond receiving an active treatment, when questioned by the investigator immediately after the intervention.;At the end of the study, it was observed a percentage of 60% of subjects, included in the new placebo group, who believed they received active treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Let there be no significant changes in the pressure pain threshold, measured by digital algometry, in the cutaneous sensitive threshold, measured by esthesiometry, and in the pain intensity, measured by 11-point numerical rating scale, after intervention in the placebo groups, from the observation of a greater variation than 5% in pre and post treatment.;At the end of study, none of the placebo groups significantly altered the pressure pain threshold, cutaneous sensitive threshold and pain intensity after treatment, presenting a difference greater than 5% of pretreatment value. Only in the adjusted motor group there was significant change less than 5% in all variables. | — |
