The research was conducted at a body farm in Australia where researchers study how bodies decompose. This, in turn, can improve forensic techniques. The team looked at a time-lapse of a decomposing body taken every 30 minutes over a period of 17 months.
The researchers expected to see some movement in the early days after death, but they witnessed movement for more than a year and a half. The motions could be the result of ligaments drying out.
