Impact of Clinical Pilates Exercise on Pain, Cardiorespiratory Fitness, Functional Ability, and Quality of Life in Children with Polyarticular Juvenile Idiopathic Arthritis.
Featured on Physle Daily · Sunday, 19 July 2026
This study looked at whether adding clinical Pilates to standard physical therapy would help children with polyarticular juvenile idiopathic arthritis (JIA), a condition where the immune system attacks multiple joints. Forty children aged 10 to 14 were split into two groups: one did conventional physical therapy alone, and the other did the same therapy plus clinical Pilates exercises, three times a week for three months. The researchers measured pain, fitness, how well the children could move and function, and their overall quality of life before and after treatment.
The group that did Pilates alongside standard therapy showed bigger improvements across all four measures compared to the group doing standard therapy alone. Pain dropped more noticeably, their heart and lung fitness improved more, they could move and do daily activities more easily, and they reported better quality of life. While these results are encouraging, they come from a single study with a relatively small group of children, so more research would help confirm whether these gains hold up consistently.
This research tested whether adding Pilates exercise to regular physical therapy helps children with JIA feel better and move more easily. The study involved 40 children who either continued with their usual therapy or added Pilates sessions to it over three months.
Children who did Pilates alongside their regular therapy experienced more relief from joint pain, felt less tired when walking or being active, found it easier to do everyday things, and reported feeling better overall. The improvements weren't tiny, but they were noticeable enough to show up clearly in the measurements the researchers used.
This doesn't mean Pilates will work the same way for every child with JIA, since all bodies respond differently and individual circumstances vary quite a bit. The study is one solid piece of evidence, though, and it does suggest that adding Pilates to regular treatment might offer some real benefits worth exploring further with your physiotherapist.

This randomised controlled trial adds a data point to the relatively sparse literature on exercise prescription for polyarticular JIA. The finding that clinical Pilates combined with conventional physical therapy outperformed CPT alone across pain (p = 0.001), cardiorespiratory markers (all p < 0.05), functional ability (p = 0.002), and quality of life (p = 0.007) suggests a measurable additive effect.
The study was reasonably well designed with pre-post measurement and a control arm, though the sample size of 40 children and the three-month intervention window are modest. What makes this particularly useful is the breadth of outcome domains: pain reduction alone would have been noteworthy, but improvements in both fitness and functional capacity speak to a more systemic benefit.
The abstract does not elaborate on adherence, dropout rates, or whether effects persisted beyond the intervention period, which would inform durability and feasibility in practice. The mechanism by which Pilates might have driven these gains is not explored in the abstract, leaving room for further investigation into whether the benefit relates to improved core stability, better movement quality, or other factors.
Children with polyarticular JIA who received clinical Pilates plus conventional physical therapy showed significantly greater reductions in pain compared to conventional therapy alone (p = 0.001).
The combined Pilates and conventional therapy group demonstrated measurable improvements in cardiorespiratory fitness and functional ability, including better performance on walking tests.
Overall quality of life improved significantly in the Pilates group relative to the control group (p = 0.007), based on standardised quality-of-life questionnaires.
