Effects of pressure garment on spasticity and function of the arm in the early stages after stroke: a randomized controlled trial

Abstract

Objective: To investigate the effects of pressure (Lycra) garment on the spasticity and function of the arm in the early stages after stroke. Design: A randomized controlled trial. Setting: Occupational therapy unit of a public hospital. Subjects: A total of 46 adults with stroke. Intervention: After random assignment, for six weeks, both intervention group and control group received a 2 hour/week conventional occupational therapy program, with the intervention group receiving an extra 6 hour/day pressure garment application (long glove). Main Measures: Modified Modified Ashworth Scale, Disabilities of Arm, Shoulder and Hand Outcome Measure, and Jebsen–Taylor Hand Function Test. Eligibility measures: Mini Mental State Examination and Modified Modified Ashworth Scale. Assessments were performed at baseline and six weeks postintervention. Results: There were 21 participants with the mean age of 51.19 (8.28) years in the intervention group and 22 participants with the mean (SD) age of 52.82 (8.71) years in the control group. The intervention group had median (interquartile range (IQR)) post-stroke duration of 1 (1) month, while for the control group, they were 2 (2) months. There was no difference in spasticity, and both perceived and actual arm functions between the groups at six weeks after baseline. Conclusion: Wearing a pressure garment on the arm for 6 hours daily had no effect in controlling spasticity or on improving arm function in the early stages after stroke.
