Concluded “Although wearing a weighted vest is not a cure-all strategy, our findings support the use of the weighted vest to remedy attentional and on-task behavioral problems of children with ADHD.” This study used 110 children with ADHD and measured with the Conners’ Continuous Performance Test-II (CPT-II) task.

This study was a literature review that stated that continued research should be conducted but that weighted vests were not recommended as a treatment option. Further it was argued that the wide use of weighted vests were not found to be supported by enough evidence to continue the practice at the risks it could cause to growing bones/spine.

Studied 30 students, over time, and found that weighted vests were not effective in task completion but “improved the in-seat behaviour and attention to task of learners diagnosed with ADHD in a classroom context.”

The abstract: “OBJECTIVE. In this study, we examined the effectiveness of using weighted vests for improving attention, impulse control, and on-task behavior in children with attention deficit hyperactivity disorder (ADHD). METHOD. In a randomized, two-period crossover design, 110 children with ADHD were measured using the Conners’ Continuous Performance Test-II (CPT-II) task. RESULTS. In the weighted vest condition, the participants did show significant improvement in all three attentional variables of the CPT-II task, including inattention; speed of processing and responding; consistency of executive management; and three of four on-task behaviors, including off task, out of seat, and fidgets. No significant improvements in impulse control and automatic vocalizations were found. CONCLUSION. Although wearing a weighted vest is not a cure-all strategy, our findings support the use of the weighted vest to remedy attentional and on-task behavioral problems of children with ADHD.”
Ok, I have to go, but there are probably more. I need to be working on my own research. 🙁
Hope this provides some insight.
