Summary

High frequency oscillations of non-ionizing electromagnetic fields range can heat deep tissues in a well-localized region. Recently, a new SWD-based model showed to be a promising tool for investigating muscle pain in humans. The main advantages of the model are its noninvasiveness, the ability to control stimulation parameters, and the convenience of the time frame in which pain and hyperalgesia are developed. This study assess the reliability of SWD pain model to induced transient and intensity-controlled muscle soreness on shoulder in healthy volunteers.

Intervention: Short-wave diathermy

The SWD will be applied using a CEC M-8 shortwave thermotherapy unit (CEC Electrónica S.R.L., Argentina) that emits RF at a frequency of 27.12 MHz. The device has two rectangular capacitive applicators (18 × 12 cm), which will be placed below and above the dominant shoulder. The coplanar application will be done using the continuous wave mode. The intensity of SWD will be gradually increased until the volunteer perceives a sensation of heat, and once familiar with this perception, the intensity will be increased until a sensation of constant but tolerable pain is evoked. This sensation will be maintained throughout the SWD application, and three repetitions will be performed. Healthy volunteers will be in a lateral supine position, and a cotton towel will be used to absorb perspiration and avoid unwanted heat effects.
