Movement Disorders. Habituation is one of those factors that has not been proven but theorized. In the aspect of attentional performance, the participants in the weighted vest condition showed considerable improvements in all three attentional variables (omission errors, RT, and RT variability) during the CPT–II task compared with the unweighted vest condition. Schweiger, A., Abramovitch, A., Doniger, G. M., & Simon, E. S. (2007). Each participant’s complete 14-min videorecorded data were randomly ordered prior to coding. Measuring impulsivity in school-aged boys and examining its relationship with ADHD and ODD ratings. Practitioners who adopt weighted vests to provide deep-touch pressure should apply the technique cautiously, especially if wearing protocols different from those in this study are used. -Attention and staying on task are behaviors that are increased the most due to weighted vest use. 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. Blanche, E. I., & Schaaf, R. C. (2001). Use of Weighted Vests in Pediatric Occupational Therapy … This site uses cookies. Each 14-min period of behavioral data was coded for every 10 s. In every 10-s block, each targeted on-task behavior was coded as one (and only one) point if the targeted on-task behavior appeared during this period, no matter how many times the behavior appeared or how long the behavior persisted in the time block. Error patterns on the Continuous Performance Test in non-medicated and medicated samples of children with and without ADHD: A meta-analytic review. (1992). The OTvest patented design is based on the experience of the creator, Nancy VandenBerg, MS, OTR, who has been a nationally certified occupational … (2003). Behavioral coding was conducted by two trained senior occupational therapists who were blinded to the specific study hypotheses and group assignments. Our aim was to increase the rigor of weighted-vest research by expanding the number of participants included, adopting quantitative research methods, using random assignment, and blinding for the experimental conditions. Johnson, K. A., Kelly, S. P., Bellgrove, M. A., Barry, E., Cox, M., Gill, M., & Robertson, I. H. (2007). A randomized, two-period crossover design was used in this study to balance the order of two vest conditions (. (2004b). 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. First, we recruited more ADHD children than did previous studies, all of which adopted a single-subject design based on a few participants, to explore the effectiveness of weighted vests. (2001). Fourth, the subtype of ADHD was not considered. Some therapists reported that there were shifts in behavior almost immediately. We're pleased to present these high quality, fully-lined weighted vests that feature velcro closures, sealed sandbag weights, and four discreet inside pockets that are designed to accommodate a variety of different size weights. In S.Smith Roley, R. I.Blanche, & R. C.Schaaf (Eds.). VandenBerg, N. L. (2001). The primary researcher conducted reliability coding. Second, limited to the experimental tool (the CPT–II task) we adopted only one variable to measure impulsivity. It is widely regarded as a safe and effective treatment for … Researchers mailed out surveys to 514 pediatric occupational therapists throughout the United States. Weighted vests or weighted blankets … Electroencephalogram theta/beta ratio and arousal in attention-deficit/hyperactivity disorder: Evidence of independent processes. This information cannot be verified and we do not know the specifics of the weighted devices used by these therapists such as weight positioning. Heterogeneity in ADHD: Neuropsychological pathways, comorbidity and symptom domains. Our findings highlight the utility of weighted vests as a means to remedy attentional and on-task behavioral performance in children with ADHD. Woods, J. R., Williams, J. G., & Tavel, M. (1989). Of the 34 children under regular medicine, 18 declined to suspend taking drugs on the days of testing, so these participants were removed from the roster. Understanding others’ experiences is invaluable because the data gives us an additional element of information as to how to use weighted vests and weighted blankets. Examining the effects of the use of weighted vests for addressing behaviors of children with autism spectrum disorders. Coders were trained through discussion and practice videos. Dissociation in performance of children with ADHD and high-functioning autism on a task of sustained attention. You can manage this and all other alerts in, Weighted vests are frequently used by occupational therapy practitioners who work with children with attention deficit hyperactivity disorder (ADHD) as a modality to provide direct somatosensory input (, According to neurophysiology studies, the, Several studies have examined the effects of weighted vests; however, a database search of PsycINFO and Medline found only one study (, Although some of the studies examining weighted vests have reported positive results (. The weight applied by vests or blankets is intended to provide proprioceptive input to the brain. Although some participants were of identified subtypes, analyzing the data was problematic because of the inadequate proportions of these subtypes among these participants. The data, which were collected under different vest conditions, provided us valuable information to explore the effects of weighted vests. Rosvold, H. E., Mirsky, A. F., Sarason, I., Bransome, E. D., Jr., & Beck, L. H. (1956). The questionnaire included 43 questions to gauge therapists’ opinions, observations knowledge, with the use of weighted vests in their practice. These vests … By continuing to use our website, you are agreeing to our. Olson, L., & Moulton, H. (2004a). Am J Occup Ther 2014;68(2):149–158. Effects of noninformational color on reading test performance of students with attention deficit hyperactivity disorder (ADHD). The demographic data for the 110 children are shown in, Demographic Characteristics of Participants, We randomized all participants into Group A or Group B to minimize the practice effect of the CPT–II task (see, Variables and On-Task Behaviors: Weighted and Unweighted Vest Conditions, Participants wearing weighted vests during the CPT–II task showed significant improvements (. The collecting and coding procedure was the same for every participant in this study. To gather information this time around, researchers conducted 21 question phone surveys. Sergeant, J. Houston, R. J., & Stanford, M. S. (2001). A possible explanation for the lack of a major difference in commission errors between the two vest conditions in this study is related to the complex mechanism of impulse control. The number of omissions, which represents inattention, was significantly decreased when the participants wore weighted vests. Dynamic changes in quantitative electroencephalogram during Continuous Performance Test in children with attention-deficit/hyperactivity disorder. Due to the patented placement of the dense, thin steel weights within the OTvest™, the OTvest™ stabilizes the trunk of the wearer. 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. Nazari, M. A., Wallois, F., Aarabi, A., & Berquin, P. (2011). All participants had to visit this room twice with a 4-wk interval. Impulsiveness subtraits: Arousal and information processing. Although the unweighted vests adopted were less than 1% of each participant’s body weight, the presence of the unweighted vest might have had an impact that was not considered. Weighted Vests and Other Weighted Tools Promote increased concentration, focus, organization, body awareness, sensory processing, and motor control with our weighted therapy tools, calming deep pressure specialties, and other helpful sensory integration products like a weighted blanket, weighted lap pad, deep pressure vest… However, the amount of weight of frequency varies and may be linked to preference or weight positioning. They remain calm and organized for 15 – 20 minutes after the vest is removed.”. Because the unweighted vest condition is not equal to a no-vest condition, however, wearing the unweighted vest still might have affected the participants. (2005). Observations of hyperactive behaviour during vigilance. Reichow, B., Barton, E., Sewell, J., Good, L., & Wolery, M. (2010). Pilot study of the effectiveness of weighted vests. 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. Weighted vests are frequently used by occupational therapy … Sensory Processing Disorder is a condition in … A multipocketed vest (Southpaw Enterprises, Dayton, OH) was used in both vest conditions (see, We chose to add 10% of each participant’s body weight to the vest in the weighted vest condition, rather than the 5% of body weight used in previous studies (, Four types of problematic on-task behaviors were collected in this study, including (1), All participants in this study were randomly assigned to one of two groups: Group A or Group B. (2011). 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). Through this 14-min computerized and standardized attentional test, we collected unbiased data on each participant’s attentional and behavioral performance. https://doi.org/10.5014/ajot.2014.009365, © 2021 American Occupational Therapy Association. Avila, C., Cuenca, I., Félix, V., Parcet, M. A., & Miranda, A. Reeves, G. D. (2001b). We also thank all therapists at Da Chien General Hospital in Taiwan who assisted with data collection, coding, and analyses. Weighted vests and weighted blankets have many similarities in that they both provide deep touch pressure to the person who uses them. Some occupational therapists report that weighted blankets and weighted vests are helpful for people with Sensory Processing Disorder. Occupational therapists’ reported experiences using weighted vests with children with specific developmental disorders. The participants in Group B completed the CPT–II task in the reverse order (see. Zhang, C., Kang, Y., & Lundy, R. F. (2011). Participants were given information about the purpose of the study and assurances of confidentiality and the right to withdraw without prejudice. Only the first author, who set the CPT task settings and helped the participants don the vests, knew whether the vest was weighted. Weighted vests … Reaction time distribution analysis of neuropsychological performance in an ADHD sample. Weighted therapy is becoming increasingly recommended in the UK by Occupational Therapists. Participants who took medicine for ADHD symptoms were asked to suspend using medication during the days of testing. Social behavior in cooperative groups: Students at risk for ADHD and their peers. Weighted devices have been used in occupational therapy settings for decades with success, thus why we continue to talk about them! Occupational therapists’ reported experiences using weighted vests with children with specific developmental disorders. Zentall, S. S., Grskovic, J., Javorsky, J., & Hall, A. M. (2000). Upon completion of the study, the researchers reached out to 51 additional pediatric occupational therapists to gather even more information regarding changes observed based on the diagnosis. This trunk stability is beneficial for those with movement disorders such as Parkinson’s, ataxia, dystonia, multiple sclerosis and more. 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. Lee, D. L., & Zentall, S. S. (2002). No significant improvements in impulse control and automatic vocalizations were found. Olson, L., & Moulton, H. (2004b). Children with ADHD were recruited from several clinics in this study. Last, further research is needed to investigate the underlying reason why the deep-touch pressure provided by weighted vests does not remedy the problem of impulsivity. Age Range of Weighted Vest Users(Olson & Moulton, 2004a), Amount of Children Who Use Weighted Vests Per Diagnosis(Olson & Moulton, 2004a). The purpose of this experiment was to determine whether wearing a weighted vest, which is used to apply deep-touch pressure input, would improve attention, impulse control, and on-task behavior during the CPT–II task for children with ADHD. -Rocking, tantrums, and wandering are the behaviors that are reduced the most due to weighted vest use. The balance of each subtype of ADHD was not considered during the period of recruitment; therefore, the participants’ ADHD subtype in this study was generally not identified. This chart tells us that most occupational therapists use two-pound weighted vests twice a day for less than one hour during desktop activities. On the basis of these advantages, the findings of our study should be valuable to discussions of the use of weighted vests. Though this was theorized, there were no reported signs of habituation. -Occupational Therapists tend to use two-pound weighted vests, twice a day, for less than one house, while their client is participating in tabletop activities. Applying observational methods: A systematic view. Occupational therapists may introduce weighted blankets, vests… Abstract Sensory-based treatment methods are commonly used by occupational therapists and others working with individual with ADHD and ASD (Wan Yunus, Liu, Bissett, & Penkala, 2015).

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). Available to target any specific part of the body, … Baranek, G. T., Wakeford, C. L., & David, F. J. Controlled visuomotor preparation deficits in attention-deficit/hyperactivity disorder. Stephenson, J., & Carter, M. (2009). CONCLUSION. Physical & Occupational Therapy in Pediatrics, 24 (3), 45-60. 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. These stylish vests are made of rugged denim and have neat, unisex-design linings. These results also support the previous single-subject design study conducted by. -“I start with 2% of the child’s body weight and then move up to 5%. Finally, some therapists reported there were no changes, but they attributed this to not using the vest frequently enough or the child not being a correct candidate for the vest. The Conners’ Continuous Performance Test (CPT; Among the CPTs, the Conners’ Continuous Performance Test–II (CPT–II; It is evident that students with ADHD exhibit higher rates of gross motor activity and fidgeting, negative verbalizations, and various other off-task behaviors relative to students without ADHD (. The testing data (omission errors, commission errors, RT, and RT variability) were collected and analyzed initially by the program itself. Weighted Modalities The therapeutic use of weight has been utilized and explored by occupational and physical therapists (rehab professionals) for many years. Bakeman, R., & Gottman, J. M. (1987). Johnson, K. A., Robertson, I. H., Kelly, S. P., Silk, T. J., Barry, E., Dáibhis, A., … Bellgrove, M. A. Collins, A., & Dworkin, R. J. The CPT–II task was administered using the standard protocol; that is, practice was given first, followed by the actual test administration. On the basis of the results and the limitations of our study, several important issues are in need of further research and clarification. For impulsivity, we hypothesized that the participants’ performance of impulse control could be significantly improved by decreasing arousal state when they were wearing weighted vests. The randomization, two-period crossover design. Barry, R. J., Clarke, A. R., Johnstone, S. J., McCarthy, R., & Selikowitz, M. (2009). A weighted vest is a convenient tool in the classroom. -Occupational Therapists tend to use two-pound weighted vests, twice a day, for less than one house, while their client is participating in tabletop activities. -Weighted vests are used primarily with preschoolers who present with autism or ADHD. Olson, L. J., & Moulton, H. J. They physically relax; I see their shoulders drop. Myles, B. S., Simpson, R. L., Carlson, J., Laurant, M., Gentry, A., Cook, K. T., & Earles-Vollrath, T. L. (2004). Despite this strength, our study does have some limitations. Wearing weighted vests truly improves three aspects of behavioral performance (off task, out of seat, and fidgets) of children with ADHD, although this method is not a cure-all strategy for their behavioral deficits. Use of Weighted Vests in Pediatric Occupational Therapy Practice. Weighted Tactile Beanbags are also Vest Weights Pair The Vest With the Activity You can use a weighted vest just for specific times and activities such as doing homework, working at a desk, taking a test, etc. (2000). behavior, attention to task, and task completion while wearing weighted vests in a school context.

No previous research has tested the effects of weighted vests on attentional performance and impulse control with a standardized assessment tool. Sensory sensitivity or underresponsiveness was improved by the proprioceptive and deep-pressure input provided by the weighted vest. Barratt, E. S. (1985). While you might be aware of the use of a weighted vest for sensory issues in children, it can also be beneficial for balance and gait training with adults. OBJECTIVE. Relations between Continuous Performance Test performance measures and ADHD behaviors. Additionally, 3 of 4 subjects asked to wear the weighted vest … A continuous performance test of brain damage. A 2001 study published in American Journal of Occupational Therapy by Nancy L. VandenBerg, found that on-task behavior increased by 18-25% in all four subjects when a weighted vest was worn for tabletop fine motor tasks. OT’s using a sensory integrative approach first utilized and promoted the use of weighted vests and weighted … The American Journal of Occupational Therapy, 55(6), 629-640. … A., & Kuester, D. A. Weighted therapy basically has a calming effect on the child. For on-task behavior, we hypothesized that the frequency of the participants’ problematic on-task behavior could be significantly decreased by the calming effects of weighted vests. (2004). Reddy, L. A., Newman, E., Pedigo, T. K., & Scott, V. (2010). Limitations that may have had an impact on results are the “novelty” effect, the limited duration.(2004). Most activities of daily living among school-age children need to be done with appropriate attention and on-task behavior; therefore, we adopted the CPT–II task as the experimental tool in this study. Electrodermal–EEG studies of arousal in Barry’s laboratory (, On the basis of these studies and related hypotheses, it appears that the complex mechanism of impulse control involves not simply control of the state of arousal but also other factors. The effects of visual stimulation on the mathematics performance of children with attention deficit/hyperactivity disorder. Both the CPT–II testing data and observational behavior data were analyzed with the statistical software package SPSS Version 19 (IBM Corporation, Armonk, NY).
