Table 3 Isolated objective outcome measures: active and passive range of motion, mrc grade strength – spearman correlation versus time

From: Measuring recovery after open lower limb fractures: combined objective functional tests and global perceived recovery outperform narrower metrics and a standard generic patient reported outcome measure
