Comparison of the mean stimulation thresholds of sensory, motor and pain for different types of electrode. Statistical results are expressed as mean ± S.E.M. NA denotes not available.
| Threshold (mA) | Hydrogel | Wet Textile | Dry Textile |
|---|---|---|---|
| Sensory | 6.3 ± 0.59 *1 | 5.9 ± 0.65 *2 | 2.35 ± 0.30 |
| Motor | 19.9 ± 1.29 † | 21.6 ± 1.42 | NA |
| Pain | 33.15 ± 2.01 ‡1 | 31.90 ± 2.01 ‡2 | 3.2 ± 0.53 |
Superscripts indicate a significant difference in sensory threshold between: *1 the hydrogel and dry textile electrodes, p < 0.05; *2 the wet textile and dry textile electrodes, p < 0.05; † the hydrogel and wet textile electrodes, p < 0.05; or a significant difference in pain threshold between: ‡1 the hydrogel and dry textile electrode, p < 0.05; ‡2 the wet textile and dry textile electrodes, p < 0.05.
