Abstract: Objective To explore the role of diaphgram fatigue in the death from hanging with bound upper limbs of rabbits. Methods Rabbits were hanged with upper limbs bound, then the data of EMGdi. were gathered Results By analyzing power spectral of EMGdi in experiment, we compare the ratio change of H/L between pre-experiment and post-experiment. There is a significance decrease of the ratio of H/L, so it indicates that diaphgram fatigue does exist. Conclusion Diaphgram fatigue plays an important role in the death from hanging with limbs of rabbits bound.

Key words: diaphragm fatigue, hanging with upper limbs bound, EMGdi
