Frequently asked questions from our clinicians and patients.

PATIENT FAQS

HOW SOON WILL I SEE RESULTS WITH ACCEL-HEAL?

Accel-Heal stimulates the normal wound healing process during therapy. Wounds can then progress afterwards to healing. Reduction in pain, exudate and oedema may also be observed within days after starting the therapy.

WILL I FEEL ANYTHING DURING ACCEL-HEAL TREATMENT?

The electrical pulses generated by the Accel-Heal device are subsensory which means that they would not normally be felt. You may, however, experience a slight tingling sensation. This is normal and not a cause for concern. You should not experience any pain or discomfort during Accel-Heal therapy. In the unlikely event that you do, the device should be switched off and the electrode pads removed immediately.

WILL THE TREATMENT AFFECT MY ABILITY TO CONTINUE WITH MY DAY-TO-DAY ACTIVITIES?

No – Accel-Heal is small, portable and discreet. This means that the device can be tucked into the external dressing on your wound or your clothing so you can carry on as normal.

HOW BIG IS THE ACCEL-HEAL DEVICE?

Accel-Heal is a small, portable and discreet device that measures just 7cm x 4cm x 2cm.

DO ALL PATIENTS HAVE TO COMPLETE THE FULL 12-DAY TREATMENT COURSE?

Yes – the 12-day treatment must be completed for all sized wounds. For most chronic wounds, one treatment course is required to achieve effective outcomes.

CAN I SHOWER WHILST HAVING THE ACCEL-HEAL TREATMENT?

You must ensure the device is kept dry. You can shower if you have a showerproof covering to prevent the dressings and device getting wet.

HOW DO I DISPOSE OF EACH DEVICE AFTER EACH 48-HOUR TREATMENT PERIOD?

Accel-Heal devices are medical electrical devices and should not be disposed of with general waste. Used Accel-Heal devices should be decontaminated and disposed of in a Waste Electrical and Electronic Equipment (WEEE) disposal facility, provided by health establishments. Patients can hand back devices to their health care provider for disposal in the appropriate local facility.

HOW DO I SECURE THE ACCEL-HEAL UNIT?

The electrode pads adhere to the skin underneath your usual wound dressing. The device can be tucked into the external dressing on your wound or your clothing so you can carry on as normal. It is also small enough to tuck discreetly into a pocket.

WHAT HAPPENS AFTER THE 12-DAY TREATMENT COURSE?

You will continue with your standard wound treatment including compression therapy if appropriate.

WHAT HAPPENS IF MY WOUND DOES NOT IMPROVE?

Speak with your healthcare provider, who may consider a referral to a specialist such as the vascular, tissue viability or a dermatologist. A second treatment with Accel-Heal can also be considered.

CAN ACCEL-HEAL BE USED UNDER COMPRESSION?

The device can be turned off and on but wherever possible should be left in situ and switched on for the 48-hour period.

FAQS FOR CLINICIANS

WHAT MEDICAL DISCIPLINES CAN APPLY AND MONITOR THE ACCEL-HEAL THERAPY?

Accel-Heal is a single use, automated treatment that is activated by the push of a single button. As such it can be easily used and monitored by all medical disciplines, carers and patients undertaking self-care.

HOW LONG HAS THIS TYPE OF THERAPY BEEN IN USE?

Electrical stimulation therapy (EST) in general has been used for healing wounds for many years. There is a vast range of in vitro, molecular and clinical evidence to support its use. In fact, EST is arguably one of the most evidence-based therapies in wound management today, with 5 meta-analyses, 6 systemic reviews and over 30 RCTs, with the first publications about it appearing in the 1980s. 

However, there are many different treatment modalities and formats of EST. For example, there may be a requirement for different parameters to be adjusted during application; the electrical current can be delivered directly to the wound or be incorporated in a dressing.  Some modalities can deliver unpleasant sensations, while some devices are very large and therefore not suitable for use in a community setting. As a result, the use of EST has largely been restricted to specialist clinics and research practice. 

Accel-Heal is a single use, automated EST device which delivers pre-programmed, low voltage pulsed current to the wound over a 12-day period. This enables clinicians to easily use EST in everyday practice. Accel-Heal has been developed in the UK over the last 12 years where it has been undergoing clinical trials and evaluations and, more recently, has become commercially available.  Under new ownership, commercial availability is being extended to a greater number of countries and a larger number of evaluations and trials are also underway.

HOW MANY PATIENTS WERE INCLUDED IN THE RANDOMISED CONTROLLED TRIALS OF ACCEL-HEAL? WHAT WERE THE AGE GROUPS AND HOW CHRONIC WERE THE WOUNDS?

There are 23 published articles, including 10 papers and 13 posters, which describe the effects of Accel-Heal. These articles published in clinical literature describe the results from 160 patients treated with Accel-Heal.  For more details see https://staging.accelheal.com/clinical-evidence/

DOES ACCEL-HEAL START TO REDUCE A PATIENT’S PAIN IMMEDIATELY?

In some cases, Accel-Heal reduces the pain within a few hours after application. However, in the majority of patients who experience a significant reduction or complete removal of pain, this generally occurs within a few days of application.  Pain reduction is normally sustained throughout and beyond the 12-day treatment period.  (See https://staging.accelheal.com/resources-downloads/ for more details)

ARE THERE ANY GUIDELINES AND RECOMMENDATIONS IN TERMS OF INDICATIONS FOR USING ACCEL-HEAL?

Accel-Heal is indicated for use in all types of recalcitrant wounds (apart from malignant wounds), to kick-start the healing process by replacing the reduced or absent electrical energy often found in chronic wounds. Endogenous bioelectric signals are important to orchestrate tissue repair by moving different cells into and across the wound, stimulating cell proliferation and collagen synthesis and activating specific gene expression important in tissue repair. Accel-Heal is also indicated for use in painful wounds, which may be affecting a patient’s quality of life and/or where a patient is unable to tolerate other necessary wound treatments such as debridement and compression therapy. 

ARE THERE ANY CONTRAINDICATIONS FOR USING THIS PRODUCT?

Accel-Heal is contraindicated for use in patients with active cancer, including any risk of malignancy in the wound. Patients with pacemakers should consult their medical practitioner and the device should not be placed near the chest wall. Do not use neat the head for patients with epilepsy. As a precaution, due to lack of evidence, patients who are pregnant or under 18 should consult their medical practitioner. Do not place the electrode pads over broken capillaries, varicose veins, or main arteries.

WHAT ARE THE LIMITATIONS OF USING ACCEL-HEAL OR ELECTRICAL STIMULATION IN GENERAL? WHAT ARE THE LIMITATIONS IN TERMS OF DISEASES?

Accel-Heal is contraindicated for use in patients with active cancer, including any risk of malignancy in the wound. Patients with pacemakers should consult their medical practitioner and the device should not be placed near the chest wall in this patient group. Do not use near the head for patients with epilepsy. As a precaution, due to lack of evidence, patients who are pregnant or under 18 should consult their medical practitioner. Do not place the electrode pads over broken capillaries, varicose veins, or main arteries.

IS ACCEL-HEAL APPROPRIATE FOR USE IN THE ACCUTE SECTOR AND IN THE COMMUNITY? CAN IT BE USED AT HOME, IN BED? CAN IT / SHOULD IT BE REMOVED FOR SHOWERING?

It can be used in all clinical settings. Accel-Heal is a novel electrical stimulation therapy, in that it is easy to use by patients, relatives, carers and health care professionals, as an adjunct to standard therapy, enabling the patient to continue with their normal routine and treatments. As with any electrical device, it should not come in contact with water. However, the device can be easily removed from the electrode pad wires, enabling showering, or the limb can be covered by a garment such as a Limbo to prevent the device becoming wet.

HAVE ANY SKIN ALLERGIES BEEN EXPERIENCED WITH THE ACCEL-HEAL PADS?

To date, over 12,500 devices have been applied to patients and there have only been a handful of reports of reactions to the skin under the pads.  Clinicians sometimes report some redness under the pads, but often this is when the pads were placed too close to the wound edge which caused exudate leakage underneath it. 

The pads are hydrogel based and are therefore easily removed without causing skin trauma.  In patients with known sensitivities, it is recommended to check the pads more frequently during early use, rotate the position of the pads during dressing changes, and, in the case of heavy exudate, ensure the pads are placed well away from the wound bed and positioned horizontally across the wound to avoid gravitational moisture.  Where there is friable skin immediately adjacent to the wound, it is recommended the pads are placed farther apart. The device will automatically adjust to ensure the same level of current is supplied irrespective of the distance and individual skin conductivity.

CAN ACCEL-HEAL BE USED ALONGSIDE HBOT?

There is no reported experience of using Accel-Heal with hyperbaric oxygen therapy (HBOT) and there have been no safety assessments of its use within the hyperbaric oxygen chamber.  Given the mode of action is different, it could conceivably be synergistic in accelerating healing and reducing pain if used in between hyperbaric oxygen therapy sessions, but further studies would be needed to validate this.

IN WHICH TYPE OF WOUNDS DO YOU SEE THE FASTEST RESULTS?

Typically, smaller wounds with lower duration are more likely to respond faster in terms of healing and wound contraction. However, it has been used on larger wounds with a long duration equally successfully but wound contraction is understandably slower and the clinical presentation/changes maybe more subtle.  Pain reduction can be seen in a range of different wound sizes and duration within a short period.

IS ACCEL-HEAL EFFECTIVE ON SACRAL PRESSURE ULCERS OR ISCHIAL PRESSURE ULCERS STAGE 4?

Accel-Heal can be used on any chronic wound and is only contraindicated in fungating wounds. The holistic needs of the patient need also to be considered, including factors such as nutrition and pressure off-loading. A Cochrane review of the use of electrical stimulation for pressure ulcers has been undertaken (Arora et al 2020) and it has been recommended for use in recalcitrant category 2-4 pressure ulcers by NUPUAP 2014, with strength A evidence.  Caution needs to be taken with the electrode wires, which could cause pressure injury if not protected. The recommended placement of the pads is away from any potential pressure points when the patient is sitting. Accel-Heal monitors current flow through the electrode pads and automatically adjusts the voltage to ensure the required current program is delivered, regardless of variables such as distance between the electrode pads, and individual patient characteristics such as hydration level of the skin. Therefore, even when the pads are placed at quite some distance from each other, the required electrical stimulation will still be delivered. The electrode pads could be placed on the outer buttocks or hips, and they would still be effective.

CAN ACCEL-HEAL BE USED FOR MODERATELY AND HEAVILY EXUDING WOUNDS?

It is important to determine the cause of the high exudate, whether it is due to the underlying aetiology such as venous/lymphatic drainage from the limb, infection, biofilm, heart disease, underlying fistula etc. The underlying aetiology needs to be addressed, such as compression therapy, wound infection management. However, due to a reduction in inflammation by the electrical stimulation, a marked reduction in exudate has been noted during and following Accel-Heal therapy.  In the case of moderate or heavy exudate it is recommended to change the dressings more frequently, at least initially, in order to monitor the exudate levels and the electrode pads. Place the pads horizontally to avoid the pads becoming too wet from gravitational moisture.

CAN YOU USE ACCEL-HEAL ON ARTERIAL OR MIXED AETIOLOGY ULCERS?

Always try to re-vascularise through angioplasty or by-pass surgery where possible. If, however, the patient is not suitable or where there is a large venous component of the arterial insufficiency, then that is the only place where reduced compression can be truly justified. Many of these wounds can be very painful. While there have been no studies undertaken yet by Accel-Heal specifically on arterial ulcers, there is no reason the science in terms of reduction in inflammation and gene expression which occurs, wouldn’t be transferable to mixed aetiology wounds.

HOW WOULD YOU USE THE PRODUCT FOR PATIENTS WITH NEUROPATHIC FOOT ULCERS OR PARALYSIS?

Accel-Heal might help with painful neuropathy and well as painless neuropathy. If the wound is stalled, and/or there is a biochemical imbalance and if you have also addressed any underlying factors, then you can apply the device to see if that starts the wound healing process.  Pain reduction often happens very quickly and only needs one 12-day period of therapy. Similarly for treating a stalled or static wound, it is recommended to use it for the 12 days and wait and see. Often what you will find is a change in the healing trajectory from being plateaued, to being stimulated again with wound size reduction. Don’t use it again unless you see another plateau. So, it’s a very specific device to kick-start that wound in the next phase, it’s not like a product that we are saying you use over a long period of time, which would be an increased cost. It’s a short duration treatment for a specific need.

CAN ACCEL-HEAL BE USED WITH PYODERMA GANGRENOSUM?

In treating this disease you need to ensure you have the correct diagnosis and biopsies. High doses of topical steroids are helpful. If a good result is achieved with those, then the patient may benefit from compression. While it is difficult to obtain a clear-cut definition of how to manage this disease, due to scattered numbers and not many people building up a vast experience of managing these wounds, but if painful, Accel-Heal could be used as an enabler to have compression. Also, sometimes systemic steroids can be beneficial.

DOES ACCEL-HEAL HELP WITH LYMPHEDEMA ASSOCIATED WITH VENOUS WOUNDS?

Patients with lympho-venous disease require a multi-disciplinary approach to this long-term condition, which mainly involves compression therapy, intensive skin care and in some cases, manual lymphatic drainage or surgery.  However, there is evidence that Accel-Heal can reduce peri-wound oedema and is a therapy that should be considered within the multi-disciplinary approach.  (See  https://staging.accelheal.com/app/uploads/2020/07/Study-to-evaluate-the-effect-of-low-intensity-pulsed-electrical-currents-on-levels-of-odema.pdf)

DOES ACCEL-HEAL REDUCE OEDEMA WITH VENOUS WOUNDS?

Patients with lympho-venous disease require a multi-disciplinary approach to this long-term condition, which mainly involves compression therapy, intensive skin care and in some cases, manual lymphatic drainage or surgery.  However, there is evidence that Accel-Heal can reduce peri-wound oedema and is a therapy that should be considered within the multi-disciplinary approach.  (See  https://staging.accelheal.com/app/uploads/2020/07/Study-to-evaluate-the-effect-of-low-intensity-pulsed-electrical-currents-on-levels-of-odema.pdf)

WHAT IS YOUR RESEARCH ON THE USE OF ACCEL-HEAL FOR FUNGATING WOUNDS?

There is currently no evidence to support the use of the Accel-Heal in fungating wounds, and indeed it is contraindicated in patients with cancer in the wound as it may stimulate tumour growth.  However, if informed consent is obtained from the patient, and the benefits such as pain reduction and exudate reduction outweigh any potential risks, then it can be considered for palliative care.

WHAT ABOUT ITS USE IN PAEDIATRICS?

Accel-Heal is not contraindicated in children but users should proceed with caution as there have been no published studies or evaluations in children.

What is the criteria for a second application of Accel-Heal?

For most wounds, once the 12-day Accel-Heal therapy has been completed, the wound continues to progress towards healing. For some of long duration (i.e. over 12 months), for very large wounds, or patients with challenging comorbidities that have weak underlying healing potential, a second treatment with Accel-Heal may be necessary to maintain the wound on a healing trajectory.

A second therapy is appropriate, if there was some response to the first treatment (i.e. pain reduction and/or wound size reduction) but the wound healing subsequently stalls or deteriorates. This can be the case in the event of a wound infection.

In general, it is recommended to wait approximately four weeks, to enable the first therapy to have its full effect, as the wound continues to heal after the therapy has been completed. However, there is no issue in using consecutive treatments if deemed clinically appropriate.

Can Accel-Heal affect the cardiac function of the patient?

Evidence (Greener 2018) has reported that Accel-Heal does not affect the cardiac function of the heart. However, although suitable for lower limb wounds, patients with cardiac pacemakers should not wear the device near the heart (Philbin et al 1998; Badger et al 2017).

USING ACCEL-HEAL

WHAT ELECTRICAL STIMULATION PARAMETERS DO YOU RECOMMEND? ARE THERE GUIDELINES FOR THIS?

Accel-Heal is a low voltage biphasic and monophasic pulsed current device.  In contrast to other electrical stimulation devices, Accel-Heal delivers a fixed and automatic, pulsed electrical stimulation therapy with a current varying from 40 to 500micro Amps (μA) at a frequency varying from 10 to 900 Hz during a 30-minute treatment program.  The treatment program is repeated every 2 hours in the first 24 hours and every 4 hours in the second 24-hour period. Each Accel-Heal device provides the 48-hour cycle of electrical stimulation. Six individual, 48-hour devices are supplied in a treatment pack and are applied consecutively to deliver the 12-day therapy.

DOES THE ACCEL-HEAL ELECTRODE HAVE TO BE PLACED ON A NON-WEIGHT BEARING REGION OF A DIABETIC FOOT ULCER?

High compression therapy can be applied over the two electrode pads. However, under compression, caution needs to be taken with the electrode wires connecting the pads to the device, which could cause pressure injury.

 

Therefore, the recommended placement of the pads on a diabetic foot ulcer should be away from areas such as the sole of the foot.  Try to place the electrodes either side of the wound, with the wires away from any weight-bearing areas. Accel-Heal automatically adjusts the voltage to ensure the required current program is delivered, regardless of variables such as distance between the electrode pads, and individual patient characteristics such as hydration level of the skin. Therefore, even when the pads are placed at some distance from each other, the required electrical energy will still be delivered to the wound. The electrode pads can therefore be placed to the sides of the foot or the dorsum and the treatment to the wound is still effective. (See the Accel-Heal application guide) https://staging.accelheal.com/app/uploads/2020/03/Accel-Heal-Application-Poster-20_S1_WEB.pdf

HOW DO YOU MANAGE THE WIRES UNDER HOSIERY TO STOP PRESSURE?

One commonly used method is to place a foam dressing or other cushioning dressing under the wires up to the top of the hosiery.

WHAT DOES THE THERAPY FEEL LIKE? DO PATIENTS LIKE IT?

Accel-Heal delivers a sub-sensory level of pulsed current. Most patients have no sensation from the therapy. If some tingling is felt, this may be due to either the patient being dehydrated or the wound bed being very dry. Rehydrating the patient and the wound can be beneficial in these cases. In general terms, patient feedback and concordance to treatment from patients when using Accel-Heal is excellent as they feel engaged in the treatment, happy to see their pain addressed and the healing of the previously stalled or slow healing wound, stimulated.

IS THE WOUND DRESSING KEPT ON FOR THE 12-DAY DURATION?

Accel-Heal therapy is used alongside standard wound care, including compression therapy, so changing the dressings or bandages should be done based upon normal practice intervals. The electrode pads can either be left in place at dressing change (up to a maximum of 7 days) or changed at the same time. Sufficient electrodes are present in each 12-day therapy pack to allow for changes every 2 days if required.  The 48-hour Accel-Heal device can be easily changed without disrupting the dressing or the electrodes by the patient, carer, or clinician.  (See here for application videos https://staging.accelheal.com/resources-downloads/)

WHAT FREQUENCY / PARAMETERS DOES ACCEL-HEAL USE?

Accel-Heal is a low voltage biphasic and monophasic pulsed current device.  Accel-Heal delivers a fixed automatic, pulsed electrical stimulation therapy with a current varying from 40 to 500micro Amps (μA) at a frequency varying from 10 to 900 Hz during a 30 min treatment program.  The treatment program is repeated every 2 hours in the first 24 hours and every 4 hours in the second 24-hour period. Each Accel-Heal device provides the 48-hour cycle of electrical stimulation. Six individual, 48-hour devices are supplied in a treatment pack and are applied consecutively to deliver the 12-day therapy.

WHAT ARE THE. PARAMETERS USED BY THE ACCEL-HEAL PRODUCT?

Accel-Heal is a low voltage biphasic and monophasic pulsed current device.  Accel-Heal delivers a fixed automatic, pulsed electrical stimulation therapy with a current varying from 40 to 500micro Amps (μA) at a frequency varying from 10 to 900 Hz during a 30 min treatment program.  The treatment program is repeated every 2 hours in the first 24 hours and every 4 hours in the second 24-hour period. Each Accel-Heal device provides the 48-hour cycle of electrical stimulation. Six individual, 48-hour devices are supplied in a treatment pack and are applied consecutively to deliver the 12-day therapy.

IS THE ELECTRIC STIMULATION DELIVERED BY ACCEL-HEAL SIMILAR TO THE CURRENT USED IN TENS DEVICES?

Accel-Heal is a low voltage biphasic and monophasic pulsed current device.  Accel-Heal delivers a fixed automatic, pulsed electrical stimulation therapy with a current varying from 40 to 500micro Amps (μA) at a frequency varying from 10 to 900 Hz during a 30 min treatment program.  The treatment program is repeated every 2 hours in the first 24 hours and every 4 hours in the second 24-hour period. Each Accel-Heal device provides the 48-hour cycle of electrical stimulation. Six individual, 48-hour devices are supplied in a treatment pack and are applied consecutively to deliver the 12-day therapy.

Other types of electrical stimulation, for example TENS, are delivered at higher voltages above the threshold for sensory stimulation and in doing so interact with the nervous system to block pain signals. TENS can provide short-term pain relief while the TENS machine is being used. However, low voltage pulsed current electrical stimulation devices, such as Accel Heal, are sub-sensory, acting locally at the cellular level and so contribute to modulating the underlying healing process and reducing those factors causing pain, which continues long after the Accel-Heal device has been used.

WHAT WOULD BE THE DIFFERENCE BETWEEN USING ACCEL-HEAL AND USING ANY TNS UNIT?

Accel-Heal is a low voltage biphasic and monophasic pulsed current device.  Accel-Heal delivers a fixed automatic, pulsed electrical stimulation therapy with a current varying from 40 to 500micro Amps (μA) at a frequency varying from 10 to 900 Hz during a 30 min treatment program.  The treatment program is repeated every 2 hours in the first 24 hours and every 4 hours in the second 24-hour period. Each Accel-Heal device provides the 48-hour cycle of electrical stimulation. Six individual, 48-hour devices are supplied in a treatment pack and are applied consecutively to deliver the 12-day therapy.

Other types of electrical stimulation, for example high voltage pulsed current (HVPC) and many forms of TENS are delivered above the threshold for sensory stimulation. Electrical stimulation therapy devices do not need to evoke such strong physical responses to stimulate the appropriate cellular effect in the wound bed.  TENS can provide short-term pain relief while the TENS machine is being used. However, Accel-Heal will enable the wound to continue healing with pain reduction, even after the 12-day therapy.

IS A 12-DAY THERAPY WITH ACCEL-HEAL ENOUGH FOR A PATIENT WHO CANNOT TOLERATE COMPRESSION THERAPY? OR CAN IT BE REPEATED IF THE PATIENT NEEDS MORE THERAPY TIME?

One 12-day therapy is usually sufficient to reduce the pain to enable full strength compression therapy. The pain reduction should then be sustainable after the 12 days as wound healing moves forward. Should pain return then a second treatment may be appropriate based upon clinical judgement. Further work is ongoing to look at multiple sequential uses of Accel-Heal in certain patients with particularly recalcitrant non-healing wounds, and more guidance will be provided on this in the future.

HOW OFTEN DO YOU MAKE A SECOND OR THIRD TREATMENT CYCLE WITH ACCEL-HEAL?

Further research is being undertaken to identify the types of wounds/patients who may benefit from two or three 12-day periods of Accel-Heal therapy, but for the majority of chronic wounds one 12-day dose is generally sufficient to both reduce pain and kick-start the wound healing process. Should there be a good initial response to the therapy, but then the wound becomes stalled again, or the pain increases, then a second 12-day therapy can be considered to re-initiate healing and/or reduce the pain. This is more likely to be in particularly recalcitrant wounds or in patients with many underlying co-morbidities.

AFTER THE FIRST TREATMENT AND, IF WORKING, SHOULD THERE BE A GAP BETWEEN TREATMENTS?

Further research is being undertaken to identify the types of wounds/patients who may benefit from two or three 12-day periods of Accel-Heal therapy, but for the majority of chronic wounds one 12-day dose is generally sufficient to both reduce pain and kick-start the wound healing process. Should there be a good initial response to the therapy, but then the wound becomes stalled again, or the pain increases, then a second 12-day therapy can be considered to re-initiate healing and/or reduce the pain. This is more likely to be in particularly recalcitrant wounds or in patients with many underlying co-morbidities. The second 12-day treatment can be applied immediately especially if pain is a major consideration but generally, it is recommended leaving for a few weeks to see if healing re-starts without further intervention.

DO YOU NEED TO CONTINUE TREATMENT FOR THE FULL 12 DAYS EVEN IF THE WOUND IMPROVED DRAMATICALLY DURING THE INITIAL DAYS OF TREATMENT?

You need at least 12 days to change the many chemical mediators that are below the wound.  It is a 12-day therapy course, so the whole treatment pack needs to be used, similar to completing a 7-day antibiotic regime.

CAN COMMUNITY TVNS PRESCRIBE ACCEL-HEAL? WHAT ABOUT GPS?

Accel-Heal is available on UK drug tariff in part 5a – appliances. Nurse prescribers and GPs in the UK are able to prescribe it on FP10.

IS IT POSSIBLE TO USE COMPRESSION THERAPY FOR PATIENTS WITH CHRONIC DISEASES OF DEEP LOW LIMB VEINS, DVT FOR INSTANCE?

This question relates to compression therapy rather than electrical stimulation with Accel-Heal. Compression therapy is indicated for use to aid venous return, thereby preventing, or healing venous leg ulceration.

HOW CAN YOU REASSURE PATIENTS ABOUT USING ACCEL-HEAL WHO MAY BE WORRIED ABOUT ELECTRICAL STIMULATION?

Clinicians rarely experience barriers from patients to using the therapy. Explanations should be given to patients in language that they understand. As one clinician has told us: “Getting patients to understand how electrical stimulation can stimulate wound healing is a huge challenge. – I have to scratch my head to understand the science behind all that.  But I have never had a barrier from the patient from a pain point of view.”  The non-medicated action of the treatment instead of taking pain killers is beneficial so weI have not had any barriers to it. (See patient story at https://www.youtube.com/watch?v=kEjlpNxKGmo&feature=youtu.be )

How far does the electrical signal travel between the Accel-Heal electrode pads?

In-vitro studies (Greener 2018) have concluded that the current can travel up to 160cm between the two electrodes. However, in practice, the device incorporates a function which monitors current flow and adjusts voltage to enable it to deliver the prescribed treatment current, irrespective of distance between placed electrodes. This enables some flexibility in application across the anatomy. Should this not be possible then an indicator will flash orange to show an error.

How far does the electrical signal travel, lateral to the electrode pads?

The electrical signal travels at least 45cm lateral to the electrode pads (Greener 2018).

If the signal travels at least 45cm lateral to the electrode pads, can I use it for multiple wounds?

Studies have demonstrated benefits to multiple wounds in the same vicinity using one Accel-Heal therapy, e.g. multiple circumferential leg ulcers. However, the wound(s) need to sit between the two electrode pads. It is recommended to apply the electrode pads closest to the largest wound initially. If there is a response to the largest wound, but no response to the smaller wound(s) then a second Accel-Heal therapy can be considered.

How deep does the electrical signal penetrate when using Accel-Heal?

An in-vitro study (Greener 2018) demonstrated the electrical signal penetrates to at least a depth of 6cm, using gelatin to replicate human tissue.

Can I apply the electrode pads to the dorsum or medial/lateral side of the foot, even when the wound(s) are present to the plantar?

Yes. Accel-Heal monitors current flow through the electrode pads and automatically adjusts the voltage to ensure the required current program is delivered, regardless of variables such as distance between the electrode pads. In-vitro studies (Greener 2018) have demonstrated that the electrical signal was present in all foot pad positions when using Accel-Heal (including the dorsum, plantar, heel, ankle and hallux).
