Effectiveness of physical therapy in axillary web syndrome after breast cancer: a systematic review and meta-analysis.

After breast cancer surgery, some people develop axillary web syndrome, a tight cord-like tissue under the arm that limits movement and can delay further cancer treatment. This review looked at what physiotherapy approaches have been tested for it, comparing exercise and stretching programs, manual therapy techniques like scar massage and myofascial release, and combinations of the two. Across nine studies, exercise and stretching came out ahead, being linked to faster return of arm movement, less pain, better quality of life, and fewer disability scores, while manual therapy alone showed weaker results.

When the researchers pooled data specifically on pain, only three small studies were available, and the reduction reached was not clearly statistically significant. This matters because axillary web syndrome affects real function and treatment timing, but the evidence base remains thin, built on a limited number of trials with small sample sizes, so confidence in any single approach stays limited.

If you've had breast cancer surgery, you may have heard of or experienced axillary web syndrome, sometimes called cording, where a tight band forms under the arm and makes it hard to move your shoulder fully. Researchers looked at what physiotherapy treatments have been studied to help with this, including exercises and stretching, hands-on manual therapy like massage, and combinations of both. Across nine studies, exercise and stretching programs seemed to help people regain arm movement faster, feel less pain, and report better quality of life and less disability compared with manual therapy approaches, which showed weaker results.

However, when researchers specifically combined the pain data, only three small studies were available, and the improvement seen was not clearly a reliable statistical finding. This means that while exercise-based approaches look promising for this condition, the overall research is still limited in size, and firmer conclusions would need more and larger studies before anyone could be confident about which treatment works best.

This systematic review and meta-analysis, following PRISMA methodology and registered in PROSPERO, identified nine randomized controlled trials and controlled clinical trials addressing physiotherapy management of axillary web syndrome after breast cancer surgery, drawn from 188 initially identified records across five databases. Interventions clustered into exercise and stretching, manual therapy including scar massage and myofascial release, and combined approaches. Narratively, exercise and stretching were associated with faster restoration of range of motion, reduced pain, improved quality of life, and reduced disability compared with manual therapy alone, though the abstract does not report a direct head-to-head statistical comparison establishing superiority.

The meta-analysis itself was restricted to pain as an outcome, pooling only three studies with small sample sizes, yielding an effect estimate of -0.82 with a confidence interval of -1.67 to 0.03, which crosses zero and therefore does not represent a statistically significant reduction. Clinicians should weigh this as a low-certainty evidence base: few pooled studies, small samples, and heterogeneous intervention types limit generalizability. No risk-of-bias grading, heterogeneity statistics, or adverse event data are reported in the abstract, further constraining interpretation of intervention safety or robustness.
