INTRODUCTION: The Pison Neural Monitor is a wrist worn biosensor that detects neuromuscular signals in the forearm. PURPOSE: The purpose of this study was to determine the effect of temperature on the accuracy and false positive rate (FPR) on the neural monitor. METHODS: Participants (n=6, 28.3±8.9 years, 179.3±9.6 cm, 80.7±15.5 kg, 17.0±2.0 cm wrist circumference) were assigned to either hot (2 males, 1 female) or cold (2 males, 1 female) and completed 6 trials at each temperature in a randomized and counterbalanced repeated measures design. Participants rested in a seated position at three different temperatures in either the heat (35°C, 42.5°C and 50°C with 40% relative humidity) or in the cold (-10°C, -2.5°C and 5°C with 40% relative humidity) with 15-minute recovery between exposures at room temperature (22°C with 35% relative humidity). Accuracy was defined as the ratio of correctly identified gestures while FPR was defined as the ratio of incorrectly classified gestures. Several gestures were performed prior to the first exposure, and after each 15-minute rest in each temperature. RESULTS: Accuracy in the cold was lower at -2.5°C (77.0±27.4%, p=0.011) and -10°C (79.7±16.6%, p=0.042), but not at 5°C (85.3±17.9%, p=0.371) than at room temperature (93.7±11.1%). The same pattern was observed for FPR in the cold where a FPR was higher at -2.5°C (0.127±0.166, p=0.011) and -10°C (0.143 ± 0.156, p=0.042), but not different at 5°C (0.117±0.142, p=0.371) than at room temperature (0.034±0.103). Accuracy in the Heat was lower at 50°C (73.9±21.1) than at 20°C (85.3±15.6, p=0.013) and 35°C (84.2±15.1, p=0.030), but not different than at 42.5°C (81.7±12.5, p=0.148). FPR was not different between temperatures in the heat (p>0.05). CONCLUSION: Caution may be warranted when using Pison Neural Monitor in extreme hot and cold conditions if stakes are high and optimal accuracy is needed.
