A yoga trial makes room for an honest null result
A three-arm study of young people with visual impairment found no clear advantage for either movement programme.
An early peer-reviewed report published in Scientific Reports on 28 October describes a randomised trial involving 164 adolescents and young adults with visual impairment in India. Mindfulness-based yoga and physical exercise were compared with a waitlist, with assessments at eight and 32 weeks. Neither programme showed superiority on the reported primary or secondary outcomes.
Changes over time need a comparison
Some measures improved during the study, but the groups changed similarly. Within-group changes therefore cannot establish an advantage for yoga or exercise. The authors identify adherence, follow-up and more focused outcomes as priorities for further work.
For teachers, this is a reason to keep a particular study and its setting in view. A null result does not settle every question about accessible practice. It does prevent this trial from becoming a confident promise of benefit. The accepted report remains subject to further editing before its final version.
