Transition Aged Individuals With Cerebral Palsy Have Larger Clinical Gains With Visual Performance Feedback During Power Training.

The study was nonrandomized, and the lead author assigned participants to groups to balance GMFCS level and age, so selection differences could have influenced the results. Only 20 participants were included, and the groups were unbalanced (9 visual feedback, 11 no visual feedback) because recruitment was interrupted by the pandemic. Different physical therapists treated the two groups, so the effect of visual feedback cannot be separated from therapist delivery. The final statistical analysis was not performed by a blinded assessor. The groups had different baseline values shown in Table 1, although the analysis adjusted for baseline outcome. Participants had to have enough cognition to use the feedback and follow physical therapist instructions, and none were undergoing concurrent physical therapy, so the study does not show how the treatment works alongside other therapy. The supplied text does not report dropout or session attendance details.

The investigators reported no financial or nonfinancial disclosures related to this project.

Do not conclude that visual feedback alone caused the gains. Both groups received 8 weeks of power training, and separate physical therapists treated the groups, so the feedback effect is mixed with therapist delivery. The groups were not randomly assigned.
