Abstract
The electrical stimulation (ES) modalities can be used to promote pain relief or to generate muscle strength. However, it is observed that there are few studies that analyze the Pressure Pain Tolerance Threshold (PPTT) in parameters that promote muscle strengthening. We aim to verify and compare PPTT after EE with parameters indicated for muscle strengthening in healthy patterns. For this, 51 women randomized into three groups participated (n = 17 each): RUSSIAN, AUSSIE and FES. ES was applied for 10 minutes with motor-level intensity to the right quadriceps muscle. The left quadriceps was used as a control. PPTT in the rectus femoris muscle was investigated by pressure algometry before, immediately after, 30 minutes after and 1 hour after electrostimulation. When compared to the control, the FES group shows a statistically significant increase in LTDP immediately after ES (p = 0.009), while the RUSSA group shows statistical difference 30 minutes after ES (p=0.007), but with a significant increase on the control side. In the AUSSIE group, there was no statistical difference between the sides in any of the evaluated hypotheses. Comparing the moments on the experimental side, the FES group shows a significant increase in PPTT immediately after and 30 minutes after ES (p=0.03). The other comparisons do not show independent differences. The data studied suggests that ES can increase PPTT through FES when parameters for muscular strengthening are applied.
