Introduction

Congratulations on your purchase and welcome to Philips! To benefit fully from the support that Philips offers, register your product at www.philips.com/pain-relief/register.

Read this user manual carefully before you use the PulseRelief device. The PulseRelief device is available without prescription. To achieve optimal treatment success with your PulseRelief device, we recommend that you use it according to the treatment instructions in this user manual. If you need further information or have questions, please visit www.philips.com/pain-relief or contact the Philips Consumer Care Centre in your country.

Intended use

The PulseRelief is intended to be used by adult consumers who experience mild to moderate chronic pain or acute post-surgical pain. The purpose of this device is to provide pain relief through transcutaneous electrical nerve stimulation (TENS). You can also use it for electrical muscle stimulation (EMS). The device is suitable for home use.

TENS and pain management

Transcutaneous electrical nerve stimulation (TENS) is a non-invasive pain relief method for which clinical proof exists that it can help relieve pain. Physiotherapists and other healthcare professionals use TENS daily as part of their treatment. TENS treatment passes electrical pulses across the intact surface of the skin to activate the underlying nerves. Clinical evidence suggests that TENS produces pain relief in a similar way to the nervous system's own pain-relief mechanisms, for instance similar to massaging a painful area. The device uses a rechargeable battery to generate pulses. These pulses are applied to the skin through self-adhesive hydrogel electrodes. You can choose one of the 15 pre-set TENS programs with different pulse settings and you can adjust the intensity of the pulse according to your own preference.

Electrical muscle stimulation

Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, uses electric pulses to evoke muscle contraction. A stimulation device generates pulses and delivers them through electrodes on the skin close to the muscles you want to stimulate. The pulses mimic the way the central nervous system makes the muscles contract. You can choose one of the 5 pre-set EMS programs.

Pain management

We all want to enjoy doing our daily activities. When you experience pain, however, the instinctive reaction is to avoid pain by reducing your activity level. As a result, you become less fit and less able to enjoy doing the things you like. Staying active, without overdoing it, is important to avoid being trapped in a persistent pain cycle. The key to self-managing your pain is pacing: distributing periods of activity and periods of rest over the day in a way that feels most comfortable for you. The key to pacing is spreading out your activities and ‘taking a break before you need it’. To get more tips on pacing and how to self-manage your pain, tap the info icon in the Philips Treatment App and select ‘Pain Toolkit’.

Contra-indications, reactions and side effects

Contra-indications

Do not use the device if:

• you have a cardiac pacemaker, implanted defibrillator or other implanted metallic or electronic device (e.g. a drug delivery system), as use in these cases could cause electric shock, burns, electrical interference, or even death.
• you have a heart disease.
• you have epilepsy.
• you are in the first trimester of your pregnancy, as the effects of TENS on the development of the foetus are as yet unknown. Avoid use over the uterus during pregnancy to reduce the risk of inducing labour. If you are pregnant, always consult your doctor or midwife before use.

• you have a cognitive impairment.

• you have venous or arterial thrombosis or thrombophlebitis. If you use the device for EMS, there is a risk of mobilising the blood clot.

• you have undiagnosed pain, unless your doctor recommends use of this device.

Reactions

Stop using the device and consult your doctor if you experience adverse reactions from the device.

Possible adverse reactions may include the following:

• skin irritation beneath the electrodes, although the gel used on the electrodes is not known to cause allergic reactions
• burns beneath the electrodes
• headaches or other painful sensations
• nausea or feeling faint

Side effects

• After EMS, some muscle soreness may occur some time after the treatment.
• Some reddening of the skin under or around the electrodes may occur during and shortly after EMS treatment. Skin reddening usually disappears within two hours after treatment. If the skin continues to be red for more than a day, please consult your doctor.

Important safety information

Warnings

General warnings

• Read this user manual carefully and always adhere to the treatment instructions.
• This is a medical device. Keep the device out of the reach of children. Children may not be able to use it according to the instructions in this user manual.
• This appliance is not intended for use by adults with reduced sensory or mental capabilities.
  They may not be able to use it according to the instructions in this user manual and they may become agitated by the treatment.
• Do not use the device on children, as the device is not designed to use on children.
• Do not modify the device or the electrodes. This could cause improper functioning.
• Only use the adapter supplied to charge the device. Use of another adapter may cause a hazardous situation.
• This device is designed for use by and on a single adult person.

Do not apply to or treat the following parts or areas

• Stimulation on the sides of the neck over the carotid sinus may have severe adverse effects on your heart rhythm or blood pressure.
• Stimulation on the front of the neck may cause severe muscle spasms that could close your airway and result in breathing difficulties.
• Do not apply stimulation across your chest because the introduction of electrical current into the chest may cause rhythm disturbances to your heart, which could be lethal.

- Stimulation across the head or on opposite sides of the head must be avoided, as the effects on the brain are unknown.

- Do not place the electrodes on skin that is not intact, clean or healthy. Open, irritated or otherwise damaged skin may lead to the delivery of too much current to the area, which may potentially cause burns.

- Do not place the electrodes near cancerous lesions, as this may have a negative impact on the cancerous lesion.

- Do not place the electrodes on areas of skin that lack normal sensation. This may cause you to be unaware of the high intensity current administered, which may result in electrical skin burns.

- Do not place the electrodes over open wounds or rashes. Open wounds may lead to the delivery of too much current to the area, potentially leading to burns. It might also cause substances in the electrode to enter the skin.

- Do not place the electrodes over swollen, red, infected or inflamed areas or skin eruptions (e.g. phlebitis, thrombophlebitis and varicose veins). Stimulation must not be applied to areas with known thrombosis or thrombophlebitis, as stimulation may increase circulation, resulting in a greater risk of emboli.

- Do not place the electrodes inside body cavities, e.g. the mouth. This device is not designed for internal application.

Do not use the device in the following conditions

- Do not use the device if you are in the care of a doctor and have not consulted your doctor first.

- Do not use the device if you have a tendency to bleed internally due to any impact or injury.

• Do not use EMS stimulation to contract a muscle if contraction of the muscle may disrupt healing. For instance, if the muscle or tendon is torn, muscle contraction may exacerbate the tear, just like a voluntary contraction. This may also be the case after a recent surgical procedure or following acute trauma or fracture. Muscle contraction in case of tendinitis may also worsen symptoms.
• Do not use the device while driving, operating machines or performing any other activity in which electrical stimulation can put you at risk of injury.
• Do not use if you are likely to fall asleep during the treatment, as this may cause you to sense injuries too late. If you use the device at bedtime, set the timer to make it switch off automatically.
• Do not use while in the bath, shower or swimming pool. This increases the risk of electric shocks and burns to the skin.
• Do not apply stimulation in the presence of electronic monitoring equipment (e.g., cardiac monitors, ECG alarms), which may not operate properly when the electrical stimulation device is in use.
• Do not use the device when you are connected to high-frequency surgical equipment. This may result in burns on the skin under the electrodes and may damage the device.
• Do not use the device within less than 1 metre from shortwave or microwave medical equipment. Close proximity to this equipment may cause unstable device output.
• Portable RF communications equipment (including peripherals such as antenna cables and external antennas) should be used no closer than 30 cm (12 inches) to any part of the device including cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment could result.

- Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.

Cautions

• If you had surgery recently, consult your doctor before you use the device. Using the device may disrupt the healing process.
• Use Burst TENS programs while resting, as these programs can result in muscle contraction in the treatment area.

Pre-set programs

The device comes standard with 15 pre-set programs for TENS and 5 pre-set programs for EMS. Please note that the order of the programs in the list does not signify a recommendation of specific programs for specific conditions. As the effect of a treatment program may strongly differ from person to person, we advise you to try out different treatment programs to find out which one works best for you.

Program overview

Conventional TENS programs

Conventional TENS is a common TENS program with high-frequency stimulation. It is based on the Gate Control Theory that states that this type of stimulation will block transmission of pain signals in the nervous system. It is comparable to ‘rubbing the pain away’. Most people use Conventional TENS for 30 minutes per session, but you can use it as often and as long as it feels comfortable. The effect is usually most perceptible during stimulation and generally wears off rather quickly after stimulation. You have to adjust the intensity of the program so that you clearly feel the stimulation. Stimulations must not feel unpleasant or painful.

Name of Conventional TENS program	Program description Suggested	treatment time
Conventional May give you a continuous tingling stimulation		No limit
Thorough stimulus	May give you a more thorough stimulating sensation	No limit
Pre-activity May give you a more local and soft stimulating sensation		No limit
Soft stimulus May give you a softer stimulating sensation, e.g. for sensitive body parts		No limit
Deep stimulus May give you a deeper stimulating sensation		No limit
Radiating pulse May give you a more radiating stimulation sensation		No limit

Burst TENS programs

Burst TENS offers a high-frequency stimulation that comes in trains of pulses. This type of stimulation is known to trigger endorphin release. Endorphins are painkillers produced by the body. You can use Burst TENS around 30 minutes multiple times a day, for example 3 times. We advise you to adjust the intensity of the Burst program so that you feel the stimulation strongly. Burst programs generally give a sharper sensation, which can feel somewhat unpleasant. It is also advised to adjust the intensity up to a level that produces visible muscle contractions in the treatment area. These contractions are not harmful. If you find these contractions too uncomfortable, you can decrease the intensity, choose a different program or move the electrodes to a different place. Apply Burst TENS programs while resting, as they can result in muscle contraction in the treatment area.

Name of Burst TENS program	Program description Suggested	treatment time
Continuous burst	May give you a pulsing burst stimulation to release endorphins in your body	30 min.*
Slow kneading	May give you a slower and massaging burst stimulation to release endorphins	30 min.*
Mild kneading	May give you a milder burst stimulation to release endorphins in your body	30 min.*
Deep kneading	May give you a more local and deeper burst stimulation to release endorphins in your body	30 min.*
Diffuse burst	May give you a more diffuse burst stimulation to release endorphins in your body	30 min.*

* optionally multiple times a day, can be changed in the app

Frequency-modulated TENS programs

Frequency-modulated TENS is a program in which the frequency of the pulse varies from high to low. This can be more comfortable or effective than the other programs in some cases. You can use frequency-modulated TENS for around 30 minutes multiple times a day, for example 3 times.

Name of Freq. Mod. TENS program	Program description Suggested	treatment time
Mixed frequency	May give you a flowing stimulation sensation	30 min.*
Pulsing massage	May give you a more pulsing stimulation sensation	30 min.*
Deep massage	May give you a slower and deeper flowing sensation	30 min.*
Gentle massage	May give you a mild flowing stimulation sensation	30 min.*

* optionally multiple times a day, can be changed in the app

Electrical muscle stimulation (EMS) programs

Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, uses pulses to evoke muscle contraction. This can for example help to strengthen muscles. Use EMS only on healthy, uninjured muscles. Apply EMS programs while resting (sitting, lying), as they result in muscle contraction. First-time users can experience electrical muscle stimulation as an unfamiliar and unusual sensation. We therefore advise you to start at a low intensity setting to get

used to the sensation before you choose a higher intensity setting. In general, stimulation must always feel comfortable. The muscle contractions must not feel exhausting, strenuous or tiring. After strenuous exercise or exertion, we advise you to use a lower setting to avoid muscle fatigue.

Name of EMS program Program description Suggested		treatment time
Muscle stimulation pulse	May give you a nice soothing sensation	30 min.*
Muscle stimulation flow	May give you a comfortable tingling sensation	20 min.*
Muscle stimulation wave	May give you a mild contracting and relaxing sensation	30 min.*
Muscle stimulation flux	May give you an energising muscle sensation	25 min.*
Muscle stimulation bounce	May give you a rhythmically relaxing sensation	20 min.*

* optionally multiple times a day, can be changed in the app

Note: The Treatment App is an app that can be used for PulseRelief (PR3840) and BlueTouch (PR3733). The installation procedure is the same for both devices.

Using the device

Attaching the electrodes and the device

1 Make sure that the skin you want to place the electrodes on looks healthy and is free from wounds or rashes.

For TENS: Do not place the electrodes on red or inflamed skin and skin with open wounds, cancerous lesions or rashes.

For EMS: Only place the electrodes on healthy, uninjured muscles.

2 Clean the skin with a moist cloth and dry it. The skin you want to place the electrodes on must be dry, clean and free from cream or lotion.

Note: Dirt, grease or particles left on the skin may lodge themselves in the hydrogel of the electrodes. This has an adverse effect on the adhesive power of the electrodes.

Illustration of a hand holding a blue object, possibly a medical or cosmetic item (no text or symbols visible)

3 Take the electrodes from the plastic bag and check them for damage and signs of wear.

Caution: Do not use electrodes whose use-by date has expired. The use-by date is shown on the resealable plastic bag.

Note: Replace the electrodes when they are damaged or dirty, when they have lost their adhesive power or when stimulation becomes uncomfortable, i.e. when you experience an unpleasant stinging or biting sensation.

4 Pull the electrode off the liner and place it on the skin at the place you want to treat. See section ‘Electrode placement’ below and the placement guide.

Illustration of a hand holding a small object with a blue arrow pointing to it, next to a blue square (no text or symbols)

5 Place the second electrode on the body part you want to treat.

Note: Always place the electrodes on the skin before you connect the device.

Note: Do not place the electrodes on top of each other or so close to each other that they touch each other.

Illustration of a hand holding a medical or electronic device with blue arrows indicating motion (no text or symbols)

6 Attach the device to the electrodes. The device units have magnets in the centre to ensure easy connection to the metal connectors of the electrodes. When the device units lock onto the electrodes properly, you hear a click.

Note: You can wear the electrodes with the device units attached to them under your clothes, also during treatment.

Note: Consult the electrode placement guide for the recommended position for the electrodes during treatment. This is only a recommendation. You can perform all activities allowed as intended use and not warned against in chapter ‘Important’ when you wear the device on your body. You can also continue to wear the device on your body in between treatments.

Electrode placement

To get maximum results from stimulation, it is important to place the electrodes correctly. Always make sure that you have normal skin sensation in the treatment area before you attach the electrodes. The optimal place may vary slightly from person to person, so try moving the electrodes around until you get the most effective results. In some cases, it can be helpful to mark the spot for future use. For suggestions regarding placement of the electrodes, see the ‘Electrode Placement Guide’. Please note that you may need assistance to place the electrodes on certain spots on your body.

As a rule, place the electrodes on or near the treatment area. Stimulation may result in visible muscle contraction, especially in burst TENS programs (programs 7 to 11). This is not harmful, but if you find these contractions uncomfortable, try moving the electrodes to a different place. Please note that when you use EMS programs (programs 16 to 20), muscle contraction is a desired effect. If no muscle contraction occurs in an EMS program, you have not placed the electrodes correctly or you have chosen a too low intensity.

Do not place electrodes over the carotid sinus on the sides of your neck or on the front of your neck, across your chest or on your head. Do not place electrodes on red or inflamed skin and skin with open wounds, on cancerous lesions or rashes (see chapter 'Contra-indications, reactions and side effects').

Problem Possible cause		Solution
The battery indicator on the device was orange and then the device switched off.	The battery is empty.	Charge the device (see chapter ‘Preparing for use’).
The battery indicator on the device is solid orange.	The battery is low.	This means that the battery has 30% of its capacity left. Recharge the device as soon as possible (see chapter ‘Preparing for use’).
I experienced an unpleasant sensation when I touched the connectors of the device or the electrodes.	You did not end the treatment in the app or did not press the on/off button on the device before you removed the device.	Always end the treatment in the app or press the on/off button on the device before you remove the device from your skin. In this way, you avoid the unpleasant sensation when you touch the connectors of the device or touch the electrodes. This sensation is unpleasant but not harmful.
The treatment feels different or less pleasant than usual.	The intensity is too high or too low.	On the program settings screen in the app, tap + or - to increase or decrease the intensity. You can also choose a different treatment program.
	The electrodes are not in the right place.	Switch off the device and detach it from the electrodes. Remove the electrodes from the skin and move them to a slightly different place.
	The electrodes are not properly attached.	Switch off the device and detach it from the electrodes. Check if the electrodes are attached to the skin properly.
	The electrodes are too dirty.	You can try to clean the electrodes (see chapter ‘Cleaning’). If this does not help, replace the electrodes.

Problem Possible cause	Solution
The electrodes are worn.	Replace the electrodes.
You are using electrodes that are past their use-by date.	Remove the electrodes and use new ones that are not past their use-by date.
