To evaluate the immediate and 4-week effects of compression garments (CG) on balance using a force platform during 8 different visual, static, and dynamic conditions in hypermobile Ehlers-Danlos Syndrome (hEDS) patients. Methods: Thirty-six participants were randomly assigned to a group: physiotherapy alone (PT, n = 19) or physiotherapy and daily CG wearing for 4 weeks (PT + CG, n = 17). Both attended 12 physiotherapy sessions (strengthening, proprioception, and balance exercises) for 4 weeks. Primary outcome: sway velocity of the centre of pressure (COP) measured before, immediately with the CG, and at 4 weeks. Secondary outcomes: ellipse area, Romberg quotient, and pain. Results: Sway velocity in dynamic conditions decreased immediately with the CG. After 4 weeks of intervention, sway velocity (95% CI 4.36u201339.23, effect size 0.93) and area (95% CI 146u20133274, effect size 0.45) on the laterally oscillating platform with eyes-closed improved more in the PT + CG group than the PT group. Romberg quotient on foam cushion improved more in the PT + CG than the PT group. Pain decreased in both groups after 4 weeks with no between-group difference. Conclusion: CG combined with physiotherapy improved dynamic balance measured with COP variables significantly more than physiotherapy alone in people with hEDS. Trial Registration: NCT03359135.
