  • Page 5: How Tens Works

    2. HOW “TENS” WORKS TENS stands for Transcutaneous Electrical Nerve Stimulation. TENS blocks nerve signals and stimulates the release of endorphins - your body’s own natural defences against pain. TENS is safe, drug-free and has been used successfully by thousands of pain sufferers. TENS sends gentle stimulation through the skin which works in TWO ways: Pain Gate TENS stimulates the sensory nerves, which carry touch and temperature signals. These nerves go to the same connections in the spine as the nerves carrying pain. A strong sensory signal will block the pain signal travelling...
  • Page 6 Endorphin Release At low frequency settings, and slightly stronger outputs, TENS drives the motor nerves to produce a small, repetitive muscle contraction. This is seen by the brain as exercise and this promotes the release of endorphins – your body’s own natural pain killer. The relief builds up and normally takes about 40 minutes to reach a maximum level which can last for hours after the machine is switched off. By using TENS you can expect to achieve a significant reduction in pain, if not complete relief from pain. • TENS is effective for pain from a very wide range of causes. • It doesn’t appear to provide relief from internal pain other than period pain. • You can use low frequency (<10 Hz) programmes on acupuncture points, to achieve similar effects to acupuncture. • With neurogenic pain (caused by inflamed nerves) such as shingles and neuralgia, TENS may initially increase the pain. We recommend that you only use TENS for these conditions under medical supervision.
  • Page 7 • You can safely use TENS as long as it gives you pain relief. The effect may wear off after a few hours (this is called “accommodation”). If this happens, take a break of an hour or so before trying again. The Endorphin Release settings should not be used for more than about 40 minutes. Like any exercise, settings that cause muscle movement may cause aching muscles if used too long. 3. HOW ‘EMS’ WORKS EMS stands for Electrical Muscle Stimulation and has successfully been used in medical rehabilitation and training in competitive sports. EMS produces intensive and effective muscular contraction, generating extraordinary training effects and rapidly enhancing performance. In rehabilitation, EMS is a well-established method for treatment of a broad field of musculoskeletal diagnoses. Electrical stimulation of an intact peripheral nervous system may create motor responses in patients with impaired or lost ability for voluntary muscle activity. EMS is commonly used for: Neuromuscular Facilitation, Muscle Re-education, Muscle Training, Prevention/Slowing of Atrophy/Hypotrophy, Preventing Postoperative Muscle Weakness, Reduction of Spasticity, Maintaining or Increasing Range of Motion,...
  • Page 8 Training of Partial Peripheral Nerve Damage with Signs of Reinnervation, Treatment of Scoliosis, Incontinence Treatment. EMS is a complement to other physical therapy and should always be combined with active mobility, strength, coordination and functional training. In training, the technology for electrotherapy is used for all kinds of muscular exercise - warm-up, strength, speed, power, resistance, endurance, recovery and also for rehabilitation. EMS is well known and works as an excellent complement to regular training. Advantages of EMS Use of EMS may lead to faster progress in the patient’s treatment program. The method is simple and appropriate for treatment in the clinical setting as well as for self-treatment at home. Successful athletes all over the world have discovered the advantages of electrical muscle stimulation, such as an increase of the local circulation and the size of the muscle fibres. EMS also helps to raise the intake of oxygen as well as improving the metabolic exchange and the consumption of energy of the user.
  • Page 9 How EMS Works Muscular activity is produced by the central and peripheral nervous systems transmitting electrical stimuli to the muscles of our body. EMS uses external electrical impulses that work through the skin to stimulate the nerves supplying a specific muscle group. The muscle reacts in different ways depending on the strength of current, duration and frequency of the electrical impulse. Muscles are made up of two different types of fibre: 1. Red fibre is slower contracting and aerobic working. 2. White fibre is faster acting and capable of anaerobic working. The proportions of red and white fibres depend on the way the muscle is used. Fibre can be converted from one type to the other, depending on the signals it receives. This is known as the Trophic effect. Different frequencies have different effects; low frequencies (1-10 Hz) coupled with long impulse times, for example, have a purifying and relaxing effect through individual contractions, whereby the circulation in the treated muscle is simultaneously improved and removal of metabolic end products is supported (lymphatic drainage). The oxygen supply to the muscle is improved.

  • Page 10: Side Effects

    In contrast, by means of a rapid succession of contractions (fibrillation), medium frequencies (20-50 Hz) can put a high level of strain on the muscle, thus promoting the muscular structure. The pads are normally placed near the muscle motor nerve and the unit transmits a stimulus through the skin, with a choice of specific therapeutic patterns. The correct positioning of the pads is important (please see pages 33-38). 4. SIDE EFFECTS There are no known side effects to TENS use and long- term TENS use is not harmful. If you are using TENS for long periods of time, ensure you allow the skin underneath the pads to breathe by moving the pads every so often. If you are using EMS for long periods of time, allow adequate rest time between sessions to allow your muscles time to relax. If you experience muscle aching, simply reduce the strength of the machine or allow your muscles to rest until the aching disappears.

  • Page 14: The Programmes

    8. THE PROGRAMMES The Perfect EMS has six different, specially developed EMS programmes (A-F), two manual EMS programmes (G-H) and two manual TENS programmes (S-T). There is no one TENS setting for a particular condition and the best choice varies from one person to another, even if they have the same type of pain. Each user needs to select both the programme and the positioning of the pads that is best for them. You may need to try a few positions/programmes before finding the one that suits you. The following grid summarises the programmes available: USAGE TENS can be used for as long as is necessary. Continuous treatment is fine but electrode pads should be repositioned regularly (at least every 12 hours) to allow...

    the skin to be exposed to the air. Endorphin Release works better when the strength is high enough to cause small muscle contractions. Best results are achieved at between 20 and 40 minutes. Longer use may cause muscle ache. If you are using EMS for long periods of time, allow adequate rest time between sessions to allow your muscles time to relax. If you experience muscle aching, simply reduce the strength of the machine or allow your muscles to rest until the aching disappears. 9. PROGRAMME SETTINGS The effect of Electrical Stimulation on the body depends on the following current settings: Pulse Waveform This describes the time function of the excitation current which may be either monophasic or biphasic. With monophasic pulse trains, the current flows in one direction. With biphasic pulses, the excitation current alternates its direction (the current flows back and forth).
  • Page 16 The Perfect EMS uses only biphasic pulse trains as they reduce strain on the muscle, leading to less muscle fatigue as well as safer application and also reduce the risk of skin irritation under the electrode pads. Pulse Frequency Frequency indicates the number of individual pulses per second and is indicated in Hz (Hertz = pulses per second). It can be calculated by working out the inverse value of the periodic time. Different types of muscle fibres react preferentially to different frequencies. Slow-response fibres tend to react to lower pulse frequencies up to 15Hz, while fast-response fibres only respond to frequencies over approximately 35Hz. With pulses of approximately 45~70Hz, there is permanent tension in the muscle (tetany) combined with premature muscle fatigue. Higher pulse frequencies can therefore preferably be used for elasticity and maximum strength training. Think of weight lifting: a higher pulse frequency corresponds to higher weights.
  • Page 17 For TENS: A frequency of 110Hz is good at blocking pain signals. A low frequency of 4 or 10Hz allows for the release of endorphins, the body’s natural pain relief mechanism. Pulse Width Pulse width is used to indicate the duration of an individual pulse in microseconds (millionths of a second). Pulse width also determines the penetration depth of the current. In general, a greater muscle mass requires a greater pulse width. A higher Pulse Width is also more likely to activate pain nerves, so there is a fine balance between maximum muscle stimulation and tolerable sensation. EMS: 50μS for small muscles like the face, up to 350μS for large muscles. TENS: 50 to 250μS. The pain relief effect does not seem to be very dependent on Pulse Width, so the choice depends mainly on comfort. Generally a setting of 200μS is effective.
  • Page 18 Pulse Strength Setting the strength is dependent on each individual user and is determined by a number of parameters such as application site, skin circulation, skin thickness as well as quality of electrode contact. The actual setting should be effective but should never produce any unpleasant sensation such as pain at the site of application. In TENS programmes, you should always be aware of a strong tingling sensation, but any setting which leads to pain must be avoided. With prolonged application, you may need to increase strength as nerves get used to the stimulation and become less sensitive (known as accommodation). In EMS programmes, the object is to produce powerful muscle contractions. The strength of the current should be increased to about three times the level at which you can first feel the tingling, or to as high as you can stand without causing pain. You will probably feel that electrical contraction is more powerful than a voluntary contraction, because the current also stimulates your sensory nerves. The signals have a pain-relieving effect. You may find the sensation uncomfortable to start with, so that you may not get up to therapeutic strength at the start of treatment.
  • Page 19 The strength can be increased during the course of the treatment, as you become accustomed to the sensation. Voluntary muscular activity is more effective than stimulation and it may improve progress if you combine voluntary contraction with stimulation. The powerful muscle contractions caused by electrical stimulation give rise to training aches, which usually disappear within a week. After treatment tingling sensations may continue or your skin may feel numb, this is normal. WORK is the time in seconds that muscle is stimulated (not including Ramp time). The Perfect EMS offers a range of work periods from 1 - 40 seconds. REST is the time in seconds at zero strength in between stimulation (i.e. when the muscle is at rest). The Perfect EMS offers a range of rest periods from 1 - 40 seconds. The EMS programmes use an Active Rest – low frequency pulses help to clear metabolites in between Work periods. Work/Rest Ratio. If you are working muscles you need to allow a rest period to allow metabolites to clear. At settings above 20Hz, you should allow at least twice as long a Rest as the Work time. Thinking of weight lifting again: with higher pulse frequency (large weight) use a high Strength, short Work time, and long Rest time to simulate a small number of repetitions.
  • Page 20 RAMP is the time in seconds taken to move up and down between zero and the set stimulation strength (i.e. the time taken to move between the Work stimulation and the Rest period). The Perfect EMS offers Ramp periods from 0 – 5 seconds. Constant and Burst Modes The TENS programmes offer a choice of modes. Constant mode is when the sensation is continuous versus Burst mode when the sensation comes in bursts (on and off). Burst gives a combination of Pain Gate and Endorphin Release but the squeezing feeling may not be as comfortable. 9.2 MANUAL TENS PROGRAMMES (S-T) In TENS Manual programmes (S-T) you can select and change the following parameters using the ‘T’ timer button: Parameter to Change Display Symbol Flashes FREQUENCY PULSE WIDTH μS CONSTANT/BURST Treatment Timer (minutes)
  • Page 21 After using programmes S-T, when you turn the device off and turn it on again, all parameters will be remembered.

To turn the unit OFF, press the ON/OFF button on the top of the unit and hold for at least 3 seconds until the display turns off. The unit will turn OFF automatically: • When the timer reaches zero. • If it is left at zero strength for more than 5 minutes. The unit will start with the program you used last and at 50% of the strength you were last using. At first use, or after changing batteries, the display shows that the unit is automatically set in Programme A at zero strength.
  • Page 24 STRENGTH CONTROLS The buttons marked CH1 ▲ , CH1▼, CH2▲, CH2▼ are strength controls. The left hand buttons ▲ ▲ change strength in the left hand lead (CH1) and the ▼ ▼ right hand buttons change the right hand lead (CH2). To increase strength in steps of 1, press and release the top part of the two channel buttons, marked ▲. The strength levels are shown on the LCD. The strength control buttons will not operate until the unit is properly connected to you. If the Perfect EMS detects a disconnection in either channel it will automatically return the strength in that channel to zero and flash ‘CH 00’. The Perfect EMS has 90 levels of strength. Rather than making multiple presses, if you hold down either of the ▲ buttons for >2 seconds the strength will change continuously until you release the button. You may not feel any sensation over the first few presses. Continue pressing until the sensation is strong but comfortable.

PROGRAMME CONTROL The button marked ‘P’ is the programme control. The Perfect EMS has six different, specially developed EMS programmes (A-F), two manual EMS programmes (G-H) and two manual TENS programmes (S-T). When the unit is first switched on it automatically enters Programme A. Each time you press and release the ‘P’ button, the programme changes and the programme letter is shown on the LCD. Each time you change the programme, the strength level reverts back to zero. This is a safety feature to alleviate any sudden feeling of a surge, as each programme gives a different sensation.
  • Page 26 TREATMENT TIMER The ‘T’ button can be used to set the session duration and to select manual parameters for adjustment. When you switch the unit on, it is automatically set at Continuous, (displayed as ‘C’) in all programmes except B, C & H, which means that the unit will continue functioning until you switch it off. When you press the ‘T’ button, the ‘min’ symbol will flash. You can set session times of 10, 20, 30, 45 or 90 minutes with the CH1 ▲ and CH1 ▼ buttons. Press ‘T’ again to save your selection. The display shows the session duration next to the clock symbol. The unit automatically counts down the minutes set and switches off when this reaches zero. LOW BATTERY An empty battery symbol will show when you need to change the batteries. The unit will shut down approximately 2 minutes after this.
  • Page 27 KEYPAD LOCK If you do not press any keys for 30 seconds, the keypad will lock so that only the keys marked ▼ will work. This is to avoid accidental changes in settings. To unlock, hold down either the CH1▼ or CH2▼ button for a few seconds until the lock symbol disappears from the display. OPEN CIRCUIT CUTOUT If the Perfect EMS is not correctly connected to your body, the strength in the channel which is not properly connected will automatically reset to zero. This is to prevent sudden changes if a broken connection is re-made. If this occurs, check the lead wire connections and ensure all pads are in complete contact with the skin.

    12. CONNECTING LEAD WIRES Insert the lead wire plugs into the base of the unit. Attaching the electrode pads to lead wires Push the pin ends firmly into the pigtail ends of the electrode pads. The lead wires may be damaged by rough handling and should be treated with care. Lead wire colour coding The ends of the lead wire are black (-ve) or red (+ve). This coding is provided for some professional uses. For most TENS applications, you can ignore the colour coding.

  • Page 32: Positioning Of Electrode Pads

    13. POSITIONING OF ELECTRODE PADS 13.1. TENS ELECTRODE PAD PLACEMENT • TENS works one vertebra at a time. You need to stimulate the sensory nerves that enter the spine at the same level as the nerve carrying your pain. Since you don’t know exactly where your nerves are, the simplest thing is to apply the pads around or near to the source of the pain. • TENS best activates the nerves if it travels along the nerve rather than across it. So place one pad farther from the spine than the source of the pain and place one pad closer. • The nerves wrap around the limbs and torso, so you may have to try a few positions before you get the best effect. • If the pain is in, or close to, your spine you can place one pad either side of the spine. • You may feel more sensation in one pad than the other. This is normal – it depends on where the pads are placed in relation to your nerves. The following pictures show some typical pad positions for a range of common complaints.
  • Page 33 NOTES: • For symptoms not illustrated, seek advice from your doctor or physiotherapist. • The electrode pads must always be used in pairs (two pads on each channel), so that the signal can flow in a circuit. • Always check unit is switched OFF before attaching or removing pads. • The Perfect EMS resets the strength to zero if the pad or lead is disconnected from your body. This is to prevent sudden changes in sensation when the pad is re-connected. • For areas that are difficult to reach, why not ask a friend to help you attach the pads?
  • Page 34 ELECTRODE PAD POSITIONS Neck & Shoulder Low Back Pain Tension Sciatica Shoulder Pain Knee Pain Elbow Pain Ankle Pain Headache/Nausea Leg Pain See section 17 for information on where you should not place electrode pads.
  • Page 35 13.2. EMS Electrode Pad Placement Electrode placement for EMS is very important for obtaining the best results. Place two electrodes over the bulk of the muscle, with one electrode over the muscle’s motor point. The motor point is the area on the skin that is located closest to the motor nerve’s entry into the muscle – about 1/3 of the way down the muscle from the spine. Here, it is easiest to trigger a contraction by electrical stimulation (see images on pages 37-38). Experiment by moving the electrode across the skin until you locate the point over the muscle that gives the cleanest contraction. In the examples on the following pages, the pads are marked +ve (red) and -ve (black) to match the red and black leads. The positive (red connector) electrode should be closest to the spine. Large muscle groups may require stimulation with two channels, that is, four electrodes simultaneously. The electrode pads must always be used in pairs, so that the signal can flow in a circuit. NOTE: Always check that the unit is switched OFF before attaching or removing pads. Use 50x50mm square electrode pads for all areas except the face, where smaller 25x25mm diameter electrodes...
  • Page 36 may be necessary (these can be purchased as a separate accessory - see Section 18). When exercising smaller muscles, take care to adjust the strength slowly as the motor nerves may be more sensitive and using smaller electrodes increases the current density. Example EMS Electrode Pad Positions Eye care You can use Programme F to stimulate the muscles around the eyes to reduce wrinkles and puffiness associated with the signs of aging. You will notice the muscles working straight away from the slight twitching. The activation of the muscles stimulates the circulation. This relaxing skin care also contributes to an increase in well-being, making you appear more awake and content. Use small 25x25mm round electrodes (these can be purchased as a separate accessory - see Section 18). In order to prevent triggering unpleasant sensations, you should increase the current strength very carefully.
  • Page 37 Stomach / Hips Weight reduction is effectively aided by training the stomach muscles. With the Perfect EMS, you can select singular muscles for direct stimulation. The stomach contains several different individual muscles and the central stomach muscle is responsible for giving you a slim stomach and a good upper body posture. Buttocks The bottom is equipped with a very strong set of muscles. Unfortunately, unwanted fat and cellulite zones are often to be found in this area and are very difficult to combat. Muscular training is one way of improving shape. The picture shows the possible electrode positions for building muscles.
  • Page 38 Upper Arms Our upper arms often have little shape, usually caused by a lack of movement and muscular work. The Perfect EMS can be used to carry out muscle training. In this case, it is all about stimulation of the circulation of blood. You have the option of treating the front side or the reverse side of both upper arms depending on where the need is greatest. Chest and Shoulders Building chest and shoulder muscle improves posture and movement in the upper body as a whole.
  • Page 39 Legs - Thighs and Calves It is usually a lack of trained muscles in the legs which disturbs us most, particularly in conjunction with areas of cellulite in the thigh area. Targeted muscle training for the front and back of the thigh and calves is very simple to perform.

  • Page 42: General Advice

    14. GENERAL PAD ADVICE • The electrode pads supplied are reusable but are for single patient use. • In order to obtain the best conductivity through the pads, always ensure that they are in good condition and tacky. • Before use, make sure your skin is clean and dry. • Peel the electrode pads from their protective plastic shield by holding and lifting one corner of the pad and pulling. Do NOT pull on the pigtail lead wire of the pad. • After use always replace the pads on the plastic sheet provided and place in the re-sealable plastic bag. • If the pads dry out then it is best to buy a replacement pack of electrodes. In an emergency it may be possible to restore some of the tackiness of the pad by adding a tiny drop of water on each pad and spreading around. If too much water is added the pads will become too soft. If this occurs, simply place the pads sticky side up in a refrigerator for a few hours. • In very hot weather the gel on the pads may become soft. In such cases place the pads, still on their plastic liners and in their bag, into a fridge until they return to their normal condition. • The pads provided are latex–free. • Replace pads when they lose their stickiness. Poor connection may cause discomfort and skin irritation.
