PMID 38694004WHAT IT FOUND
Repeated side-to-side rolling for 4 weeks improved throwing distance and shoulder and hip motion in seated boccia players with severe cerebral palsy.
Upper-limb band training did not improve throwing distance.
Key findings
01Interval rolling increased throwing distance from 11.09 to 11.99.
02Interval rolling improved shoulder and hip range of motion after 4 weeks.
03Upper-limb band training improved some shoulder and hip movements but did not improve throwing distance.

What it does not show
Only 10 players were studied, all seated boccia players with severe CP, so this cannot tell us how many people would respond similarly. The study only included spastic type CP, so it may not apply to other CP types. The researchers did not measure muscle strength or muscle activity, so they could not show how the training changed strength. The throwing-distance gain was small in effect size, and the study compared only two training methods. The participants were registered boccia players, so results may not transfer to people with CP who do not play boccia.
Declared interests
The authors report no conflicts of interest.
The easy way to misread this
Do not conclude that interval rolling is an established superior training method for severe cerebral palsy. This was a crossover study in 10 boccia players with spastic CP, and the throwing-distance gain had a small effect size.
