Re-establishment of rigor mortis following mechanical loosening is used as part of the complex method for the forensic estimation of the time since death in human bodies and has formerly been reported to occur up to 8-12 h post-mortem (hpm). We recently described our observation of the phenomenon in up to 19 hpm in cases with in-hospital death. Due to the case selection (preceding illness, immobilisation), transfer of these results to forensic cases might be limited. We therefore examined 67 out-of-hospital cases of sudden death with known time points of death. Re-establishment of rigor mortis was positive in 52.2% of cases and was observed up to 20 hpm. In contrast to the current doctrine that a recurrence of rigor mortis is always of a lesser degree than its first manifestation in a given patient, muscular rigidity at re-establishment equalled or even exceeded the degree observed before dissolving in 21 joints. Furthermore, this is the first study to describe that the phenomenon appears to be independent of body or ambient temperature.
机械松解后尸僵重现被用作法医估计人体死亡时间的复杂方法的一部分，此前有报道称其在死后8 - 12小时（hpm）内出现。我们最近描述了在院内死亡病例中观察到该现象持续至19 hpm。由于病例选择（既往疾病、固定不动），这些结果向法医案件的转化可能受到限制。因此，我们检查了67例已知死亡时间点的院外猝死病例。尸僵重现的阳性率为52.2%，观察到该现象持续至20 hpm。与目前认为尸僵重现程度总是低于给定患者首次出现时的观点相反，在21个关节中，重新出现时的肌肉僵硬程度等于甚至超过溶解前观察到的程度。此外，这是第一项描述该现象似乎与体温或环境温度无关的研究。
