INTRODUCTION

EXPLANATION OF PAIN

• Pain is a warning system and the body’s method of telling us that something is wrong.
• Pain is important; without it abnormal conditions may go undetected, causing damage or injury to vital parts of our bodies.
• Even though pain is a necessary warning signal of trauma or malfunction in the body, nature may have gone too far in its design. Aside from its value in diagnosis, long-lasting persistent pain serves no useful purpose. Pain does not begin until coded message travels to the brain where it is decoded, analyzed, and then reacted to. The pain message travels from the injured area along the small nerves leading to the spinal cord. Here the message is switched to different nerves that travel up the spinal cord to the brain. The pain message is then interpreted, referred back and the pain is felt.

EXPLANATION OF TENS
Transcutaneous Electrical Nerve Stimulation is a non-invasive, drugfree method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it only helps control the pain. TENS does not work for everyone; however, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity.

HOW TENS WORKS
There is nothing “magic” about Transcutaneous Electrical Nerve Stimulation (TENS). TENS is intended to be used to relieve pain. The TENS unit sends comfortable impulses through the skin that stimulate the nerve (or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain sensation the patient feels. Pain relief varies by individual patient, mode selected for therapy, and the type of pain. In many patients, the reduction or elimination of pain lasts longer than the actual period of stimulation (sometimes as much as three to four times longer). In others, pain is only modified while stimulation actually occurs. You may discuss this with your physician or therapist.

IMPORTANT SAFETY INFORMATION!
Read instruction manual before operation. Be sure to comply with all “CAUTIONS” and “WARNINGS” in the manual. Failure to follow instructions can cause harm to user or device.

INDICATIONS FOR USE
This device is designed to be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, upper extremities (arm) and lower extremities (leg) due to strain from exercise or normal household work.

CAUTIONS

1. Federal law allows over the counter (no prescription) sales of this device.

2. Do not use this device for undiagnosed pain syndromes until consulting a physician.

3. Patients with an implanted electronic device, such as a cardiac pacemaker, implanted defibrillator, or any other metallic or electronic device should not undergo TENS treatment without first consulting a doctor.

4. Patients with heart disease, epilepsy, cancer or any other health condition should not undergo TENS treatment without first consulting a physician.

5. Stimulation delivered by this device may be sufficient to cause electrocution. Electrical current of this magnitude must not flow through the thorax or across the chest because it may cause a cardiac arrhythmia.

6. Do not place electrodes on the front of the throat as spasm of the Laryngeal and Pharyngeal muscle may occur. Stimulation over the carotid sinus (neck region) may close the airways, make breathing difficult, and may have adverse effects on the heart rhythm or blood pressure.

7. Do not place electrodes on your head or at any sites that may cause the electrical current to flow trans-cerebrally (through the head).

8. This device should not be used while driving, operating machinery, close to water, or during any activity in which involuntary muscle contractions may put the user at undue risk of injury.

9. Turn the TENS off before applying or removing electrodes.

10. Isolated cases of skin irritation may occur at the site of electrode placement following long term application. If this occurs, discontinue use and consult your physician.

11. If TENS therapy becomes ineffective or unpleasant, stimulation should be discontinued until its use is re-evaluated by a physician.

12. Keep this device out of the reach of children.

13. TENS 7000 devices have no AP/APG protection. Do not use it in the presence of explosive atmosphere and flammable mixture.

14. It is recommended not to exceed a current density of 2 mA /cm2,otherwise skin irritations or burns can occur.
    We recommend that:

    • Please use specific size electrodes provided by manufacturer to avoid skin irritations or burns.
    • For smaller electrodes, the maximum current setting of the waveform should be appropriately reduced.
    • Please place the electrodes carefully, ensure that the entire surface of the electrode has good contact with the skin.

WARNINGS

1. TENS devices have no curative value.
2. TENS is a symptomatic treatment, and as such suppresses the sensation of pain, which would otherwise serve as a protective mechanism.
3. TENS is not effective for pain of central origin (This includes headache).
4. Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when TENS stimulation is in use.
5. Caution should be used in applying TENS to patients suspected of having heart disease. Further clinical data is needed to show there are no adverse results.
6. Electrodes should not be placed over the eyes, in the mouth, from the chest and the upper back or crossing over the heart, or internally.
7. Do not use while sleeping.
8. Do not use during pregnancy unless directed by your physician.
9. Simultaneous connection of a PATIENT to a high frequency surgical device may result in burns at the site of the STIMULATOR electrodes and possible damage to the STIMULATOR.
10. Operation in close proximity to a shortwave or microwave therapy device may produce instability in the STIMULATOR output.

PARAMETER CONTROLS

PULSE WIDTH (DURATION)
Pulse width is how wide each pulse is. Typically, the higher the pulse width the stronger the stimulation feels. If set high enough, sometimes it will produce a contraction which is typically not what you want to elicit with a TENS unit. Various pulse widths are capable of stimulating different groups of nerve fibers.

PULSE RATE
Pulse rate is also known as pulses per second. It is the number of times a pulse occurs in one second. This setting can be adjusted to excite certain nerves to overcome accommodation effects and will feel the sensation of steady continuous stimulation.

TREATMENT MODE

• Normal or Conventional TENS offers the practitioners complete control over all the various treatment parameters of the instrument. Burst Mode is analogous to the Low Rate TENS technique except the low frequency individual pulses are replaced by individual “bursts” of 7-10 individual pulses. It is thus a combination of Conventional TENS and Low Rate TENS. In Burst Mode, the treatment frequency is fixed by the instrument and is not adjustable with the Frequency Rate control.
• Modulated Mode attempts to prevent nerve accommodation by continuously cycling the treatment intensity. When using Modulated Mode increase the intensity only when the unit is at the maximum intensity of the modulation cycle. If the intensity is increased during a low intensity period of the modulation cycle, the patient should increase the intensity slowly until the modulation cycle reaches the maximum to insure a true maximum intensity output.
• Strength-Duration Modulation (SD1 & SD2) consists of alternating modulated amplitude and width so that one parameter is always decreasing while the other is increasing and vice versa. The amplitude decreases from the amplitude control setting and returns to that setting. The width decreases from the width control setting and returns to that setting.

TIME DURATION

• The onset of pain relief should occur shortly after the intensity setting has been determined. However, in some cases, pain relief may take as long as 30 minutes to achieve. TENS units are typically operated for long periods of time, with a minimum of 20 – 30 minutes and in some post-operation protocols, as long as 36 hours.
• In general, pain relief will diminish within 30 minutes of the cessation of stimulation.

ATTACHMENT OF ELECTRODE LEAD WIRES

• The wires provided with the system insert into the jack sockets located on top of the device. Holding the insulated portion of the connector, push the plug end of the wire into one of the jacks (see drawing); one or two sets of wires may be used.

• After connecting the wires to the stimulator, attach each wire to an electrode. Use care when you plug and unplug the wires. Jerking the wire instead of holding the insulated connector body may cause wire breakage.
  CAUTION
  Do not insert the plug of the patient lead wire into any AC power supply socket.

LEAD WIRE MAINTENANCE

Clean the wires by wiping with a damp cloth. Coating them lightly with talcum powder will reduce tangling and prolong life.

ELECTRODE OPTIONS

The electrodes are disposable and should be routinely replaced when they start to lose their adhesive nature. If you are unsure of your electrode adhesive properties, order replacement electrodes. Replacement electrodes should be approved for over-the-counter use. Follow application procedures outlines in the electrode packaging to maintain optimal stimulation and to prevent skin irritation.

ELECTRODE PLACEMENT

• The placement of electrodes can be one of the most important parameters in achieving success with TENS therapy. Placing the electrodes at least 2″ apart but no more than 6″ apart will help with successful therapy.
• Every patient responds to electrical stimulation differently and their needs may vary from the conventional settings suggested here. If the initial results are not positive, speak to your physician about alternative stimulation settings and/or electrode placements. Once an acceptable placement has been achieved, mark down the electrodes sites and the settings, so the patient can easily continue treatment at home.

CONTIGUOUS PLACEMENT

• This is the most common placement technique. It involves placing the electrodes alongside the area of localized pain site, in such a way as to direct the flow of current through or around the area of pain.
• In a single channel application, this would involve placing each pad on either side of the pain site if the pain is localized on a limb and deep within the tissue. Pad placement on the posterior and anterior aspects of the affected limb will allow the current to flow completely through the limb and thus through the endogenous pain site.
• With a two channel application, you may either direct the current flow to cross through the pain site or, in what is called the “bracket” method allowing the current flow on either side of the painful area, generally through the nerve branches that feed into the pain site.

TIPS FOR SKIN CARE

To avoid skin irritation, especially if you have sensitive skin, follow these suggestions:

1. Wash the area of skin where you will be placing the electrodes, using mild soap and water before applying electrodes, and after taking them off. Be sure to rinse soap off thoroughly and dry skin well.
2. Excess hair may be clipped with scissors; do not shave stimulation area.
3. Wipe the area with skin preparation wipes. Let the area dry. Apply electrodes as directed.
4. Many skin problems arise from the “pulling stress” from adhesive patches that are excessively stretched across the skin during application. To prevent this, apply electrodes from centre outward; avoid stretching over the skin.
5. To minimize “pulling stress”, tape extra lengths of lead wires to the skin in a loop to prevent tugging on electrodes.
6. When removing electrodes, always remove by pulling in the direction of hair growth.
7. It may be helpful to rub skin lotion on electrode placement area when not wearing electrodes.
8. Never apply electrodes over irritated or broken skin.

APPLICATION OF RE-USABLE SELE ADHESIVE ELECTRODE

Application

1. Clean and dry the skin at the prescribed area thoroughly with soap and water prior to application of electrodes.
2. Insert the lead wire into the pin connector on the pre-wired electrodes.
3. Remove the electrodes from the protective liner and apply the electrodes firmly to the treatment site. Make sure that the unit is turned off prior to applying the electrodes.

Removal

1. Turn off the unit prior to removing the electrodes.
2. Lift at the edge of electrodes and peel; do not pull on the lead wires because it may damage the electrodes.
3. Place the electrodes on the liner and remove the lead wire by twisting and pulling at the same time.

Care and Storage

1. Between uses, store the electrodes in the resealable bag in a cool dry place.
2. It may be helpful to improve repeated application by spreading a few drops of cold water over the adhesive and turn the surface up to air dry. Over Saturation with water will reduce the adhesive properties.

Important

1. Do not apply to broken skin.
2. The electrodes should be discarded and re-ordered from your physician when they are no longer adhering.
3. The electrodes are intended for single patient use only.
4. If irritation occurs, discontinue use and consult your physician.
5. Read the instructions for use of self-adhesive electrodes before application.
