No significant improvements in impulse control and automatic vocalizations were found. A common intervention tool used by therapists to target sensory integration issues in this population is the weighted vest (WV), which applies a compressive external load to users (23). With such a large sample size, the effects of weighted vests would not easily be influenced by a single or several outliers. Alberts, E., & van der Meere, J.

Effects of a weighted vest on attention to task and self-stimulatory behaviors in preschoolers with pervasive developmental disorders. For attention, we hypothesized that the participants’ attention-related information processing could be significantly improved by ignoring unrelated sensory input when they were wearing weighted vests. The surveys that were mailed could have been completed by someone who was not intended to complete the survey. In the unweighted vest condition, we assumed that no effect of deep pressure was provided because the weight of the vests was less than 1% of each participant’s body weight. Sergeant, J. 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). Only the first author, who set the CPT task settings and helped the participants don the vests, knew whether the vest was weighted.

Am J Occup Ther 2014;68(2):149–158. The testing data (omission errors, commission errors, RT, and RT variability) were collected and analyzed initially by the program itself. In addition, speed of processing and responding (RT) and consistency of executive management (RT variability) were significantly improved in the weighted vest condition. To create a blind context during the coding of each participant’s on-task behavior, we adopted the same multipocketed vest in both experiment conditions. Finally, because all the children were recruited from clinical settings in this study, our findings should not be extrapolated to the general population. Evidence of difficulties in sustained attention in children with ADDH. From neuron to behavior: Regulation, arousal, and attention as important substrates for the process of sensory integration. A total of 341 therapists responded to the survey, and out of those respondents, 193 reported using weighted vests in practice for an average of 5.3 years.
