Dynamics of brain connectivity after stroke
WebJun 16, 2024 · A rule of thumb in stroke recovery is that patients with mild deficits are more likely to make a good recovery than patients with initially more severe deficits (Fig. 2).The ‘proportional recovery rule’ assumes that patients can on average improve around 70% (+/− 15%) of their lost function within 3–6 months after stroke [50, 64, 79], with the lost … WebNov 1, 2024 · However, the abovementioned studies about the rsFC of the SMN after stroke assumed that the rsFC was stationary throughout scanning. It may not be enough to manifest brain activity as it has been reported that human brain connectivity is dynamic rather than stationary [17,18].
