The Dilemma of Waiting for Pain to Settle
Many people with ongoing musculoskeletal pain wait until it has fully settled before returning to the activities they have stopped. For persistent pain this can become a trap: activity stays avoided, capacity declines, and ordinary tasks begin to provoke more pain than they used to. Graded exposure and pacing are two approaches that aim to break that cycle by rebuilding activity in deliberate, manageable steps rather than waiting for symptoms to disappear first.
Does Pain During Activity Mean Harm?
A systematic review of randomised trials in chronic musculoskeletal pain compared exercise in which pain was allowed or encouraged with exercise that was kept pain-free. It found a small short-term benefit for pain in favour of the painful exercise, with no clear difference in the medium or long term, and none for function or disability. The authors concluded that pain during therapeutic exercise need not be a barrier to successful outcomes (Smith et al., 2017). A small randomised trial in Achilles tendinopathy reached a similar practical conclusion: patients who kept running and jumping under a pain-monitoring model improved to a similar degree as those who rested from those activities for six weeks, and no negative effects of continuing were demonstrated (Silbernagel et al., 2007).
These findings do not mean that any amount of pain is acceptable. They suggest that pain during or after activity is not, on its own, a reliable sign that damage is being done, and that the response to load over the following day or so is more informative than the pain felt at the time.
Graded Exposure: Reintroducing Feared Movements
Graded exposure is built on the fear-avoidance model, in which fear of pain leads to avoidance of movements that are actually safe, which in turn maintains disability. Treatment involves reintroducing the avoided activities in a structured sequence, starting with those that provoke the least concern. In a randomised trial in people with chronic low back pain and elevated pain-related fear, graded exposure was an effective treatment and reduced pain catastrophising and the perceived harmfulness of activities more than graded activity did, although it was not clearly better than graded activity for functional disability (Leeuw et al., 2008). It is one of several reasonable options rather than a guaranteed solution.
Where Pacing Fits In
Pacing, in a clinical sense, means spacing and sizing activity so that it is steady rather than alternating between overdoing it on good days and shutting down on bad ones. The studies above concern graded exercise and exposure rather than pacing as a stand-alone treatment, so pacing is best understood here as a practical way of applying graded loading, not as a separate intervention with its own strong trial evidence.
How much activity, at what pace and with what level of discomfort is appropriate depends on the condition, how irritable it is and what else is going on for the person. That is a question for an individual assessment, particularly when pain is severe, worsening, or accompanied by other symptoms.
