Relationships between perceived pain VAS and ΔPPT during NMES and NxES
| Pairs | Pearsons r, p value |
|---|---|
| NMES VAS vs. ΔPPT R Knee | -.070, p = .775 |
| NMES VAS vs. ΔPPT L Knee | .319, p = .183 |
| NMES VAS vs. ΔPPT Finger | .164, p = .502 |
| NxES VAS vs. ΔPPT R Knee | -.475, p = .040* |
| NxES VAS vs. ΔPPT L Knee | .154, p = .528 |
| NxES VAS vs. ΔPPT Finger | -.212, p = .384 |
VAS Visual analog scale rating of perceived pain, NMES Neuromuscular electrical stimulation, NxES Noxious electrical stimulation, ΔPPT Change in pressure pain threshold
* indicates statistical significance at the level p ≤ .05
