Within our Knowledge Transfer Partnership, ProMOTION EV1 has been through years of trials and rigorous testing with professional teams and leading academics to optimise safety and performance. ProMOTION EV1 is the first product based on new technology and science developed alongside researchers from the University of Central Lancashire and Manchester Metropolitan University.
ProMOTION EV1 has been developed with research and science in mind. We take a scientific approach to improving the therapy solutions available in elite sport.
Some of the key benefits of ProMOTION EV1 are listed below:
Benefits of Targeted Cryotherapy
High-quality evidence supports the use of cryotherapy as a short-term pain relief for acute soft-tissue injury management. 1 However, short-term adverse effects to dynamic stability and muscle strength (up to a 16% reduction) have also been reported following ice interventions. 2-4 Therefore, authors have warned clinicians to consider the potential increased risk of injury following a cryotherapy treatment, before returning to weight bearing activity.
The guidelines for injury management have introduced ‘optimal loading’ as a solution to encourage early activity to optimise recovery. 1 Emerging research suggests a targeted cryotherapy approach may help to minimise the reduction to muscle strength previously reported with ice interventions, which cooled a relatively larger surface area. 5 This would allow individuals to apply a targeted cryotherapy intervention, using the ProMOTION EV1, and then return to weight bearing activity earlier, at a lower risk of injury.
ProMOTION EV1 could minimise the adverse effects to muscle strength and dynamic stability reported following ice, through a targeted cryotherapy approach. 5-6
Innovative therapy on the move
Bleakley, McDonough and MacAuley 7 advised that for acute soft tissue injury, intermittent applications may enhance the therapeutic effect of ice in pain relief. The intermittent applications consisted of two 10-minute ice applications, with a 10-minute washout period in between.
“With ProMOTION EV1 being thermoelectric and battery-operated, individuals can intermittently use the device at ease without the need for ice, water or mains electricity.”
Sports Rehabilitation Technologist
Unique to the market
Contrast Therapy is primarily used in elite sports for post-exercise recovery. 8 For the first time, ProMOTION EV1 allows individuals to apply contrast therapy across the body at ease.
“ProMOTION EV1 provides the opportunity to tailor contrast therapy programs and allows individuals to apply contrast therapy across the body at ease.”
Precise control and maintenance
Ideal Therapeutic Range
Previous studies have identified that a local analgesic effect occurs when the skin is cooled and maintained below 13.6°C. 9 Skin surface temperatures between 10-11°C produce a reduction in metabolism of 50% and a reduction in nerve conduction velocity (NCV) occurs at a skin surface temperature of 12.5°C. 10 Therefore, it is widely accepted that the ideal therapeutic range for skin temperature is between 10-15°C. 11,12
Technical evaluations of the product have shown that the device can control and maintain skin surface temperature within the ideal therapeutic range for a 20-minute cooling intervention. A targeted cryotherapy approach, using the ProMOTION EV1, can provide the desired short-term pain relief in a population with healthy participants with induced pain. 13
ProMOTION EV1 can precisely control and maintain skin surface temperatures to achieve the desired therapeutic benefits of cooling. 5,14
The Science behind
Cold, Heat, Contrast
The guidelines published by the Association of Chartered Physiotherapists in Sports and Exercise Medicine (ACPSM) recommend the POLICE (Protection, Optimal Loading, Ice, Compression, Elevation) approach for acute soft tissue injury management: 1
- Optimal Loading
Cold therapy (also known as cryotherapy) is advised where swelling and bruising is present to reduce tissue temperature, perceived pain and inflammation. 15,16
Cryotherapy is not generally advised if stiffness is present in the muscle or joint
The ideal therapeutic range for skin surface temperature has been determined in literature as 10-15°C. 11,12
Heat therapy is recommended to relieve dull aches, particularly in the sub-acute phase (48 hours up to 2 weeks). 17
Thermotherapy is commonly used to relieve pain from delayed onset of muscle soreness (DOMS) and for patients with lower back pain. 18,19
Other therapeutic benefits include an increase in blood flow, metabolism, connective tissue elasticity, pain relief and increases range of movement (ROM) at a variety of joints. 18,20
Heat is not generally advised during the acute phase for most soft tissue injuries due to the inflammation in this stage of injury. 21
Nadler et al.15 summarised the physiological effects of cold and heat therapy (Figure 1).
Physiological effects to cold and heat therapy illustrated in Nadler et al. 15
Contrast therapy is the alternation of hot and cold therapy. 22
A systematic review established a consensus from previous studies regarding temperature applications for contrast therapy protocols as cold = 10-15°C and hot = 38-40°C. 23
The physiological basis of contrast therapy is not fully understood but one theory suggests contrast therapy protocols promote a vasodilation/vasoconstriction ‘pumping’ action in order to reduce swelling and remove waste products. 24
Other therapeutic benefits reported in literature include greater heat removal, reductions in creatine kinase, lactate, muscle soreness and an increase in muscle function. 25
Studies commonly report an improvement in the perception of recovery following contrast therapy compared to a passive recovery technique. 8,24,25
It is well accepted that the addition of compression with cryotherapy provides more therapeutic benefit than cryotherapy alone. 17
Reported benefits include greater cooling to the skin surface and deeper tissues and a reduction in pain and swelling for patients undergoing knee surgery. 26,27
The clinical guidelines advise that one dosage or approach (i.e. external static or intermittent pneumatic compression) of compression is unlikely to be equally effective across the entire soft tissue spectrum. 1
