Randomized controlled trials showing the effects of intermittent pneumatic compression on ulcer healing

Author	Number randomized	Interventions	Outcome measures	Results
Smith et al³³	45	Both groups had same dressings and stockings. Sequential IPC for up to 4h in one group	Healing	48% healed in IPC group and 4% in control group
McCulloch et al³⁴	22	Both groups had the same dressings and Unna’s boots. IPC for 60 min twice weekly in one group	Healing	100% healed in IPC group and 80% in control group
Schuler et al³⁵	53	Unna’s boots versus elasticated stockings plus IPC for 60 min in the morning and 120 min in the evening	Healing	71% healed in IPC group and 75% in Unna’s boot group
Rowland³⁶	16	Crossover trial of dressing alone with dressing and IPC for 60 min twice daily for 2–3 months	Healing	No ulcers healed in either arm before crossover
Kumar et al³⁷	47	Both groups had 4-layer bandaging IPC for 60 min twice daily for 4 months in one group	Healing	87% healed in IPC group and 92% in control group
Nikolovska et al³⁸	104	Both groups had same dressings Fast IPC for one group and slow IPC in the other group	Healing at 6 months	86% healed with fast IPC and 61% with slow IPC

Abbreviation: IPC, intermittent pneumatic compression.
