Radial extracorporeal shockwave therapy compared with manual therapy in runners with iliotibial band syndrome.

Iliotibial band syndrome is a common but under-researched overuse injury in runners, and clinicians have few trial-based comparisons to guide treatment choice between hands-on therapy and newer device-based options like shockwave therapy. This randomised trial compared radial shockwave therapy against manual therapy, with both groups also following an exercise rehabilitation programme, and tracked pain during treadmill running over eight weeks. The two approaches showed no statistically significant difference in pain reduction at either 4 or 8 weeks. Looked at separately, the shockwave group showed a statistically significant drop in pain at both time points, while the manual therapy group's improvement did not reach statistical significance at either point.

The main limitation is the very small sample, just 11 and 13 runners per group, which makes these within-group patterns uncertain and means the trial cannot establish that one treatment outperformed the other.

If you're a runner dealing with iliotibial band pain on the outside of the knee, you may have wondered whether hands-on manual therapy or shockwave therapy, a device-based treatment, works better alongside exercises. This small study of 24 runners compared the two, with everyone also doing an exercise programme, and tracked how much pain they felt while running on a treadmill over eight weeks. The researchers found no statistically significant difference between the two treatments.

People who received shockwave therapy reported a statistically significant drop in pain at both four and eight weeks, while those who had manual therapy reported improvement too, but it didn't reach statistical significance. Because only a small number of people were studied, these results aren't strong enough to say one treatment is better, and more research would be needed before drawing firmer conclusions.

For clinicians weighing radial shockwave therapy against manual therapy for iliotibial band syndrome, this randomised trial offers a direct, if small, comparison, with both groups also completing an exercise rehabilitation programme throughout. The primary outcome, pain during treadmill running, showed no statistically significant difference between groups at 4 weeks (p=0.796) or 8 weeks (p=0.155), and the magnitude of improvement did not differ significantly between arms overall (p=0.864). Within-group analysis found the shockwave group's pain reduction reached statistical significance at both 4 weeks (51%, p=0.022) and 8 weeks (75%, p=0.004), while the manual therapy group's reductions (61% at 4 weeks, 56% at 8 weeks) did not reach significance (p=0.059 and p=0.067).

This pattern should not be read as evidence that shockwave therapy outperformed manual therapy, since no significant between-group difference was detected and the shared exercise programme makes isolating either add-on's specific contribution difficult. The trial's chief limitation is its size, only 11 and 13 runners per arm, which limits confidence in both the null between-group finding and the within-group trends. The abstract does not report adverse events, so no safety conclusions can be drawn from this study.
