Table 3.
Medians (and inter-quartile ranges) of hot thresholds, cold thresholds, neutral zones, and vibrotactile thresholds at 31.5 and 125 Hz on the distal phalanges of fingers with sensorineural symptoms (Group A) and fingers without sensorineural symptoms (Group B)
| 154 fingers with any sensorineural symptom (Group A) | 86 fingers without any sensorineural symptom (Group B) | |
|---|---|---|
| Hot thresholds (°C) | 48.2 (45.7–50.9)** | 41.4 (39.2–43.0) |
| Cold thresholds (°C) | 16.8 (14.2–21.3)** | 25.8 (24.3–28.0) |
| Neutral zone (°C) | 30.6 (24.4–32.7)** | 15.3 (13.8–19.7) |
| Thresholds, 31.5 Hz (m/s2 r.m.s.) | 0.41 (0.34–0.59)** | 0.17 (0.14–0.25) |
| Thresholds, 125 Hz (m/s2 r.m.s.) | 1.19 (0.86–1.72)** | 0.35 (0.28–0.61) |
* p < 0.01, ** p < 0.001: significant increase in hot threshold or decrease in cold thresholds on fingers with sensorineural symptoms compared to fingers without sensorineural symptoms (Mann–Whitney U test)
