Key Takeaway
Consider activity pacing for cancer-related fatigue during chemotherapy, but evidence certainty is extremely low.

This systematic review and meta-analysis evaluated the effect of activity pacing-related interventions on cancer-related fatigue (CRF). The analysis included 5 studies with 617 participants, comparing activity pacing interventions to controls. The primary outcome was CRF.

Overall, the pooled effect was small and not statistically significant (SMD = -0.36; 95% CI: -0.73 to 0.00), indicating a trend toward improvement but with uncertainty. In a subgroup of patients undergoing chemotherapy (3 studies, 197 participants with breast cancer), a moderate and statistically significant effect was observed (SMD = -0.58; 95% CI: -0.87 to -0.29).

The authors note substantial heterogeneity (I² = 66%) and rate the certainty of the evidence as extremely low. Adverse events, tolerability, and long-term outcomes were not reported. Limitations include low evidence certainty and limited generalizability beyond chemotherapy patients.

Clinically, activity pacing may offer some benefit for CRF, particularly during chemotherapy, but the evidence is weak and should be interpreted cautiously. Further high-quality research is needed.

This study looked at how activity pacing affects tiredness in people with cancer. It combined information from five different studies involving six hundred seventeen participants. The main goal was to see if moving around in a planned way could help patients feel less tired.

When looking at all the data together, the results did not show a clear benefit. The change in tiredness scores was small and not considered significant by the researchers. This means we cannot say for sure that this method works for everyone.

However, results were different for patients getting chemotherapy. In this group, activity pacing showed a moderate improvement in tiredness. This suggests the method might be more helpful when used during specific cancer treatments like chemotherapy.

The study has some important limits. The results varied a lot between different studies, making it hard to draw firm conclusions. Because of this, the overall confidence in these findings is extremely low. Doctors should be careful not to promise big benefits based on this data.

Safety was not a major concern since no serious side effects were reported. But more research is needed to understand long-term effects and if digital tools make the method better.

What this means for you:
Activity pacing may help reduce tiredness during chemotherapy, but overall evidence is weak and results vary.

PURPOSE: Although physical activity is recommended for managing cancer-related fatigue (CRF), activity pacing (AP) and energy conservation are also implemented to balance activity and rest. This systematic review assessed the effectiveness of AP-related interventions and behavior change techniques (BCTs) employed in AP-related interventions for CRF management. METHODS: We searched PubMed, CINAHL, CENTRAL, and Ichu-shi databases for articles published up to February 28, 2026. After assessing the risk of bias, we performed meta-analyses for quantitative synthesis. We also identified and classified BCTs using data from the Behavior Change Technique Taxonomy version 1. RESULTS: Among the 1257 identified studies, 10 (7 randomized controlled trials [RCTs] and 3 non-RCTs) met the inclusion criteria. The effect size was small but not significant (standardized mean differences [SMD] = - 0.36; 95% confidence intervals [CI]: - 0.73 to 0.00; 5 studies; 617 participants), with substantial heterogeneity (I = 66%). Compared with controls, the intervention showed a moderate, statistically significant effect in the subgroup of patients undergoing chemotherapy (SMD = - 0.58; 95% CI: - 0.87 to - 0.29; three studies; 197 participants with breast cancer). The primary BCTs used in AP-related interventions were "goal setting," "social support," and "graded tasks." CONCLUSION: AP-related interventions may provide some benefit in improving CRF, particularly during chemotherapy. However, the certainty of the current evidence is extremely low. Although these interventions represent useful approaches, further RCTs are needed, and digitization of AP-related intervention programs incorporating effective BCTs may be beneficial.
