Key result
Abdominal compression cuts orthostatic heart rate increases by ~11 bpm and improves symptoms in pediatric POTS.
Why the study?
Although abdominal compression bands are effective for orthostatic intolerance in adults, studies evaluating their efficacy in children with postural tachycardia syndrome are limited.
Does an abdominal compression band improve standing symptoms, hemodynamics, and autonomic nervous function in children with postural tachycardia syndrome?

Does an abdominal compression band improve standing symptoms, hemodynamics, and autonomic nervous function in children with postural tachycardia syndrome?
An abdominal compression band applied at 20 mmHg effectively reduces orthostatic tachycardia and improves subjective symptoms in pediatric patients with POTS by maintaining venous return.

Abdominal compression may ease orthostatic symptoms in pediatric POTS; leaves open need for randomized confirmation before practice change.
Background: Abdominal compression is an effective nonpharmacological treatment for orthostatic intolerance. Although the efficacy of abdominal compression bands has been studied in adults, studies involving children are limited. This study investigates the efficacy of abdominal compression bands in children diagnosed with postural tachycardia syndrome (POTS), using a larger cohort and incorporating autonomic nervous function assessment via frequency analysis. Methods: A crossover study was conducted with 23 patients with POTS (mean age 13.4 ± 0.8 years), with and without abdominal compression bands (20 mmHg). Standing symptoms, hemodynamics (blood pressure, heart rate [HR], cardiac index [CI], stroke volume [SV], and total peripheral resistance [TPR]), and cardiovascular autonomic function were assessed by spectrum analysis during standing tests. These variables were compared with and without bands. Results: When standing with the abdominal compression band, subjective symptoms improved, increases in heart rate (HR) and decreases in stroke volume (SV) were suppressed, blood pressure was maintained, and cardiac parasympathetic function was improved. By contrast, in the supine position, patients showed an increased HR, decreased CI, increased TPR, lower cardiac parasympathetic function, and higher cardiac sympathetic function. Conclusion: Abdominal compression bands may relieve symptoms while standing and improve hemodynamic and autonomic nervous functions in children with POTS.

Yamawake et al. (2025) conducted an RCT in Pediatric postural tachycardia syndrome (POTS) (n=23). Abdominal compression band vs. Without abdominal compression band was evaluated on Change in heart rate upon standing (ΔHR, bpm) (p=<0.01). In children with postural tachycardia syndrome, wearing a 20 mmHg abdominal compression band significantly suppressed the orthostatic increase in heart rate and improved subjective symptoms compared to standing without the band.
