Intermittent Vacuum Therapy (IVT) is based on the rhythmic application of negative pressure (−20 to −70 mmHg) and normal pressure to the lower half of the body. These alternating pressure phases lead to periodic vascular dilatation and compression, thereby enhancing arterial, venous, and lymphatic flow [1–4]. The shear stress generated on the vascular wall mechanically stimulates the endothelium, resulting in increased release of nitric oxide (NO) [3–6]. NO induces vasodilation, improves microcirculation, and activates anti-inflammatory and regenerative signaling pathways in the tissue [5–7]. This endothelial activation forms the basis for the therapeutic effects of IVT in orthopedic and rehabilitative medicine.
Several studies have demonstrated that IVT significantly improves microcirculation [1–3, 7–10]. During the negative pressure phases, arterial inflow is promoted, while the normal pressure phases support venous-lymphatic return. Clinical studies in patients with peripheral arterial disease (PAD) have shown an increase in arterial flow velocity of up to +46 % and a rise in transcutaneous oxygen pressure (TcpO₂) by +14 % [2, 8]. This hemodynamic activation enhances the nutritive supply of the tissue, leading to a reduction in ischemic pain and improved functionality.
In orthopedic and rehabilitative settings, IVT exerts multiple beneficial effects [9–12]. In musculoskeletal injuries such as muscle strain or tear, the therapy leads to a marked reduction in pain and edema as well as accelerated hematoma resorption. In sports and rehabilitation clinics, a shortening of the individual regeneration time (Return-to-Play) by 30–50 % has been observed [10]. Postoperatively, for example after joint replacement or arthroscopic surgery, IVT improves tissue perfusion, reduces postoperative swelling, and accelerates mobilization [11]. In geriatric rehabilitation, IVT supports circulation and helps counteract deconditioning.
IVT stimulates the formation of granulation tissue and promotes angiogenic regeneration [13–15]. By improving oxygen and nutrient supply, cell proliferation is enhanced and healing time of soft-tissue injuries and postoperative wounds is reduced. Clinical data demonstrate a higher rate of complete wound healing (72 % vs 52 %) and a lower amputation rate compared with control groups [14]. These effects are associated with endothelial NO release, capillary neogenesis, and reduction of pro-inflammatory mediators [5, 6, 14].
IVT also functions as a passive lymphatic training method. Through rhythmic pressure variations, the removal of lymphatic fluid is promoted, leading to a pronounced reduction of edema [11, 15]. This is particularly relevant in postoperative and post-traumatic rehabilitation, since conventional compression techniques are often contraindicated in the early phase. The combination of vascular and lymphatic activation contributes to accelerated regeneration and pain relief.
Multiple prospective, retrospective, and experimental studies confirm the efficacy of IVT in improving hemodynamic and clinical parameters [1–4, 9–15]. A PLOS ONE study (2017) demonstrated significant improvements in macro- and microcirculation in patients with PAD. A German prospective series (Schink 2009) reported increased walking distance and reduced pain. A retrospective analysis at the University Hospital Zagreb (n = 97) revealed significantly higher wound healing rates and fewer amputations. Sports medicine applications report faster regeneration and earlier resumption of physical load. These data consolidate IVT as an evidence-based, non-invasive procedure in orthopedic and rehabilitative therapy.
IVT with VACUMED® / VACUSPORT® is used in orthopedic and rehabilitative medicine for a wide range of clearly defined indications. All applications are based on the principle of rhythmic vascular stimulation, capillarization, and lymphatic activation [9–14].
→ Pain and edema reduction, hematoma resorption, accelerated regeneration.
→ Enhanced microcirculation, lymphatic drainage, rapid mobilization.
→ Improved perfusion, activation of joint metabolism, pain reduction.
→ Anti-inflammatory effect, stimulation of resorption, pain relief.
→ Improved lymphatic outflow, tissue relief.
→ Improved cerebral and peripheral perfusion, activation of autonomic reflexes.
→ Vascular training, enhanced oxygen and nutrient supply, improved physical performance.
→ Faster lactate and CK clearance, reduction of muscular fatigue.
IVT is considered a low-risk and well-tolerated therapy [11, 16]. Treatment should not be performed in patients with acute thrombosis, unstable angina pectoris, inguinal or abdominal hernias, or during pregnancy. The procedure is painless, delegable, and suitable for both inpatient and outpatient use.
Intermittent Vacuum Therapy (IVT) represents a scientifically validated, non-invasive method that, through hemodynamic and endothelial mechanisms, enhances microcirculation, regeneration, and wound healing. In orthopedics and rehabilitation, it enables faster recovery after injury or surgery, improves functional capacity, and sustainably increases patients’ quality of life.
