Objective test–retest reliability.
| Recovery time | ICC (95% CI) | |||
|---|---|---|---|---|
| Dominant index | Non-dominant index | Dominant 5th digit | Non-dominant 5th digit | |
| 0 min | 0.38 (−0.40 to 0.73) | 0.42 (−0.33 to 0.74) | 0.30 (−0.58 to 0.69) | 0.84 (0.63–0.93) |
| 2 min | 0.84 (0.63 to 0.93) | 0.88 (0.72 to 0.95) | 0.71 (0.34 to 0.87) | 0.76 (0.46–0.90) |
| 4 min | 0.82 (0.60 to 0.92) | 0.74 (0.42 to 0.89) | 0.78 (0.49 to 0.90) | 0.76 (0.44–0.89) |
| 6 min | 0.81 (0.57–0.92) | 0.77 (0.48–0.90) | 0.81 (0.58 to 0.92) | 0.83 (0.62–0.93) |
| 8 min | 0.80 (0.55–0.91) | 0.77 (0.47–0.90) | 0.81 (0.56 to 0.91) | 0.81 (0.58–0.92) |
| 10 min | 0.80 (0.54–0.91) | 0.79 (0.53–0.91) | 0.78 (0.50 to 0.90) | 0.74 (0.40–0.88) |
| Average | 0.86 (0.69–0.94) | 0.81 (0.57–0.92 | 0.84 (0.63 to 0.93) | 0.83 (0.61–0.92) |
The lowest test–retest reliability of the ICE protocol during the two testing occasions was observed directly following immersion, with increasing reliability as recovery time progressed. There was no statistically significant difference between subjects’ dominant and non-dominant hands.
ICC Intraclass correlation coefficient; 95% CI 95% confidence interval
