Effects of very early exercise on inflammatory markers and clinical outcomes in patients with ischaemic stroke- a randomized controlled trial.

After a stroke, there's ongoing debate about how soon it's reasonable to get patients moving, and whether early exercise might influence the body's inflammatory response as well as recovery itself. This small randomized trial compared starting moderate-intensity exercise within 24 hours of an ischaemic stroke against usual care involving only regular turning and positioning, in patients with first-ever mild-to-moderate stroke. Over the first week, the early-exercise group showed trends toward lower levels of certain inflammatory markers, including interleukin-6, and higher lymphocyte levels, though the effect on fibrinogen was not consistent.

At one and three months, the early-exercise group also showed better improvements in motor function, disability, independence, anxiety, depression, and cognition, and changes in interleukin-6 were associated with later functional and motor outcomes. This is interesting because it suggests early movement might influence recovery partly through inflammatory pathways, not just through direct physical training effects. However, the trial was small, single-center, and the connections between inflammation and outcomes were correlational, so causation can't be confirmed from this design alone.

If you or someone you know has had a stroke, you may wonder how soon it's safe or helpful to start moving and exercising. This study looked at that question in a small group of adults with a first, mild-to-moderate ischaemic stroke, comparing those who began structured, moderate-intensity exercise within a day of their stroke against those who received standard care, which mainly involved being turned and repositioned regularly. The researchers found that the early-exercise group tended to have lower levels of certain inflammation-related blood markers in the first week, and better improvements over the following months in movement, daily function, independence, mood, and thinking skills compared to the usual-care group.

Changes in one inflammation marker were also linked to how well people were doing months later, though this link doesn't prove that reducing inflammation directly caused the improvement. Because this was a small trial at a single hospital, and the exercise group likely received more attention and contact from staff, these encouraging patterns need to be confirmed in larger studies before firm conclusions can be drawn.

This trial addresses a clinically relevant question: whether initiating exercise within 24 hours of an ischaemic stroke, rather than delaying mobilization, might influence both the acute inflammatory response and longer-term recovery. Forty-eight patients with first-ever mild-to-moderate ischaemic stroke were randomized 1:1 to twice-daily 45-minute sessions of very early exercise for seven days versus usual care limited to turning and positioning, with inflammatory markers assessed at baseline, day 4, and day 7, and clinical outcomes assessed at one and three months. The early-exercise group showed trends toward lower interleukin-6, leucocytes, neutrophils, and monocytes, and higher lymphocytes, alongside better outcomes in motor impairment, disability, functional independence, anxiety, depression, and cognition at follow-up.

Correlational analyses linked early interleukin-6 changes (days 4 and 7) with three-month functional independence (rs = -0.33, p = 0.019 and p = 0.021) and day 7 interleukin-6 with three-month motor impairment (rs = 0.30, p = 0.039), suggesting a possible mechanistic link between inflammatory modulation and recovery. The usual-care comparator received minimal structured attention, so differences in contact time may partly explain the observed clinical benefits. With a single-center design and modest sample size, these findings are exploratory and warrant replication before informing changes to acute mobilization protocols.
