Motor recovery after stroke in a sample of n = 412 ischemic stroke patients based on the Fugl-Meyer upper extremity (FM-UE) score. Patients with mild initial deficits make on average better recovery than patients with severe deficits. Different colors represent different recovery subgroups based on a longitudinal mixture model. The numbers next to the recovery graphs represent the proportional recovery coefficient rK, which denotes how much of the potential recovery has been achieved based on the FM-UE score. The downward arrows indicate the time constants τk in weeks, i.e., how fast patients recovered (here: reaching 1-e− 1 = 63.2% of total recovery). Of note, also initially severely affected patients (green curve) can achieve a good outcome with a relatively high recovery coefficient (rk = 0.86) but a longer time constant (τk = 9.8 weeks) compared to the other subgroups.
