Supporting evidence for Electrical Muscle Stimulation or EMS
EMS has a long history, having been used in medical applications for over a century. During that time, EMS techniques have been extensively researched and refined, showing benefits in the treatment of injury and illness, as well as being used to help maintain a healthy circulation.
EMS has been shown to improve blood flow, which boosts the circulation. The medical benefits of this can include:
- Increasing flexibility (range of motion)
- Making muscles stronger
- Slowing down muscle-wasting
EMS has been shown to help with the following medical conditions:
EMS applied to the muscles at the front on the thighs can reduce knee pain in people with Osteoarthritis (OA). EMS applied to these muscles, and to the calves, can also strengthen forward extension of the leg at the knee in people with hip Osteoarthritis (hip OA), who have undergone total hip-replacement surgery.
Anterior Cruciate Ligament (ACL) surgery
The ACL is a tough band of bodily material that joins the thigh bone to the shin bone, at the knee joint. It helps to keep the knee stable and control the back-and-forth movement of the lower leg. The ACL can become torn if the knee is twisted in a certain way (eg when skiing or playing 5-a-side football) and requires surgery to fix it. The strength of the front thigh muscles are reduced after ACL surgery following injury, but EMS combined with exercise can restore the strength of these muscles and improve the way that they work.
This simply means that blood is not flowing through the veins as well as it should. This can be due to a number of things, including problems with the valves within veins. If these valves are not working as they should, it is much harder for blood to go ‘uphill’ back to the heart.Why is Circulation Important
The calf muscle-venous pump
- The first circulation booster was launched in 2005
- Millions of REVITIVE devices have been sold worldwide
- Partnership with London South Bank University
- Since 2007 we have worked with South Bank University, Human Performance Centre whose physiologists have helped us develop the latest version of REVITIVE – REVITIVE IX
- London South Bank University physiologists have carried out a number of clinical trials on REVITIVE IX, in healthy individuals to confirm its efficacy and safety.
- Two of these trials have recently been presented as posters and abstracts at Physiology2014, London, July 2014 and publication will follow
REVITIVE Evidence – LSBU posters
Electrically stimulated lower leg exercise increases lower limb perfusion1:
The aim of this study was to compare the effects of heel/toe exercises with REVITIVE IX to stimulate the foot and calf muscles and look at the effect of blood flow in the lower limb. 16 healthy volunteers took part. It showed that REVITIVE was as effective for enhancing tissue oxygenation as heel/toe exercises and was more effective than heel/toe exercises at a) maintaining skin temperature of the lower limb and b) increasing cutaneous perfusion
Plantar Surface Electrical Stimulation Increases Blood Flow and Tissue Oxygenation2:
This study looked at the effect of using REVITIVE after (16) healthy individuals had been seated for 40mins. Even just 40mins of sitting causes some blood pooling and swelling in the lower legs. REVITIVE was as effective as continuous heel/toe raises – both carried out for 30mins, at significantly enhancing tissue oxygenation
We are now supporting a number of clinical trials with the Academic Section of Vascular Surgery, Imperial College London. This group are investigating REVITIVE in specific conditions: Venous Insufficiency, Peripheral Arterial disease and Diabetic peripheral neuropathy.
A pilot study (independently funded) in 30 healthy individuals published in Phlebology July 2014.
The effect of footplate neuromuscular electrical stimulation on venous and arterial haemodynamics1
Using REVITIVE IX this study looked at the effects of blood flow in arteries and veins while using REVITIVE. The blood flow and mean velocity increased during electrical muscle stimulation with REVITIVE. The researchers concluded that by improving blood flow REVITIVE has the ability to enhance venous return, counteract venous stasis and improve limb arterial flow.
