Intended Use: Neuromuscular Electrical Stimulation
neehab XPTM applies muscle and nerve stimulation using the principles of Neuromuscular Electrical Nerve Stimulation (NMES),
which is defined below. It applies brief electrical pulses through skin surface adhesive electrodes.
Neuromuscular Electrical Stimulation (N ES)
NMES may be defined as the application of electrical stimulation of the peripheral nervous system to contract a muscle either
through the direct activation of the motor neurons in the mixed peripheral nerve, or indirectly through reflex recruitment.
N ES Indications
• Muscle re-education
• Prevention or retardation of disuse atrophy
• Maintaining or increasing range of motion

5
2.0 Contra-Indications
•Powered muscle stimulators should not be used on patients with cardiac demand pacemakers / defibrillators.
2.1 Warnings
•The long-term effects of chronic electrical stimulation are unknown.
•Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to the carotid
sinus reflex.
•Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles may occur
and the contractions may be strong enough to close the airway or cause difficulty in breathing.
•Stimulation should not be applied transthoracically, in that the introduction of electrical current into the heart may cause
cardiac arrhythmias.
•Stimulation should not be applied transcerebrally.
•Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g. phlebitis, thrombophlebitis,
varicose veins, etc.
•Stimulation should not be applied over, or in proximity to, cancerous lesions.
2.2 Precautions
• The safety of powered muscle stimulators for use during pregnancy has not been established.
• Caution should be used for patients with suspected or diagnosed heart problems.
• Caution should be used for patients with suspected or diagnosed epilepsy.
• Caution should be used in the presence of the following:
- When there is a tendency to haemorrhage following acute trauma or fracture;
- Following recent surgical procedures when muscle contraction may disrupt the healing process;
- Over the menstruating or pregnant uterus;
- Over areas of the skin which lack normal sensation.
• Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conductive medium.
• Electrode placement and stimulation settings should be based on the guidance of the prescribing practitioner.
• Powered muscle stimulators should be kept out of the reach of children.
• Powered muscle stimulators should be used only with the leads and electrodes recommended for use by the manufacturer.
• (FOR PORTABLE DEVICES ONLY): Portable powered muscle stimulators should not be used while driving, operating machinery,
or during any activity in which involuntary muscle contractions may put the user at undue risk or injury.
• Operation in close proximity to shortwave or microwave therapy equipment may produce instability in the stimulator output.
• Electronic monitoring equipment (such as ECG monitors and ECG alarms) may not operate properly when the stimulator is in use.
SAFETY INFOR ATION

FREQUENTLY ASKED QUESTIONS
3.0 Frequently Asked Questions
Q: What is Kneehab XPT ?
A: neehab XPTM is a unique, innovative, garment-based Electrical Muscle Stimulation (EMS) product designed specifically to
treat quadriceps atrophy (thigh muscle weakness). Clinical research has shown EMS technology to be an efficacious treatment
for quadriceps atrophy, which is a symptom of almost all knee injuries. neehab XPTM can be used both pre- and post-opera-
tively to accelerate knee rehabilitation. neehab XPTM is also effective in the treatment of quadriceps atrophy resulting from
certain hip or lower limb conditions e.g. hip osteoarthritis or after hip replacement surgery.
Q: What is ULTIPATH™?
A: neehab XPTM utilises MULTIPATH™ stimulation technology, which is a highly advanced form of electrical muscle stimulation
for injury rehabilitation. MULTIPATH™ optimises rehabilitation through strong, comfortable quadriceps contractions.
EMS has been used for over 50 years to re-activate and strengthen weak muscles. MULTIPATH™ is a major breakthrough in this
area, utilising sophisticated modern engineering and software technology to focus stimulation precisely in those parts of the
muscle that optimise muscle contraction.
MULTIPATH™ stimulation enables neehab XPTM to deliver highly-focused, accurate and comfortable quadriceps contractions.
Q: What should Kneehab XPT feel like when operating?
A: When you switch neehab XPTM on and gradually increase the intensity, you will feel a mild, comfortable “tingling” or
“buzzing” sensation in your quadriceps muscles. As you increase the intensity, the muscles will begin to contract.
The channel on the inside of your thigh will increase the intensity in the inner part of the quadriceps (called the Vastus Medialis).
For some conditions, your clinician may recommend you only use this channel. The channel on the outside of your thigh will
increase the intensity in the rest of the quadriceps. Both channels are used together in general use.
neehab XPTM assists in the stabilisation of the knee by contracting the inner quadriceps before the outer quadriceps.
Q: How can Kneehab XPT help rehabilitate the knee?
A: The quadriceps muscle is the most important stabiliser of the knee. After knee injuries or knee surgery, pain and swelling
often cause disuse, which leads to muscle atrophy. An essential component of rehabilitation after knee injury is strengthening of
the quadriceps muscle. neehab XPTM works by re-educating and strengthening the quadriceps muscle through cycles of contrac-
tion and relaxation. neehab XPTM is a highly effective, yet simple and convenient way to rehabilitate quadriceps atrophy after in-
jury or surgery.
Q: How often should I use Kneehab XPT ?
A: Your prescribing clinician will advise you on the duration of your treatment program.

QUESTIONS & ANSWERS
8
Q: What should I do if treatment becomes uncomfortable?
A: Effective treatment should not cause undue discomfort. If treatment becomes painful, try lowering the intensity level slightly,
then gradually build back up to previous level. If discomfort persists, neurotech®recommends that you contact your prescribing
clinician who will advise you on usage of neehab XPTM to minimise discomfort.
Q: Can Kneehab XPT be used in conjunction with other forms of therapy?
A: neehab XPTM can be used as an adjunct to most forms of therapy for knee injuries. See page 4 of the User Manual for Contra-
Indications (situations when neehab XPTM should not be used).
Q: How often should I replace the adhesive electrodes?
A: This depends on a number of factors including skin type, storage conditions and regularity of use. As a general rule, however,
with daily application the electrodes should last at least 4 weeks. If usage is less than this, replacement should be less frequent.
Please store the adhesive electrodes in accordance with the instructions on page 16 of the User Manual.
Q: How do I position Kneehab XPT on the leg?
A: See pages 12-16 of this User Manual for full instructions on positioning
neehab XPTM on the leg.
Q: Can Kneehab XPT be used on other body parts?
A: neurotech®strongly recommends that neehab XPTM only be used as directed in this User Manual and not applied to any other
body parts.
Q: How should I care for my Kneehab XPT ?
A: See page 18 of the User Manual for full instructions on caring for your neehab unit
Q: Can I move around while using Kneehab XPT ?
A: If you need to move around during a treatment session, press the On/Off (Pause) button briefly, to pause the treatment. To
complete the treatment session, just press the On/Off (Pause) button a second time.
Q: Who should I contact if I have additional queries?
A: Contact your prescribing clinician or your neurotech®team if you have any questions regarding usage of neehab XPTM.
Q: What should I do if I experience an adverse reaction?
A: If any irritation, skin reaction, hypersensitivity or other adverse reaction is experienced, discontinue use and contact your
prescribing clinician. A slight reddening of the skin is normal under the electrodes during and for a short time after treatment.
This should disappear within approximately 30 minutes.

5.0 Setting-Up A Kneehab Treatment
Step 1 - Charge the battery
Connect the Unit to the charger (Fig. a) and plug the charger into a main’s supply socket. To remove
the Unit from the charger press the buttons on each side of the unit connector and pull apart.
You will know the battery pack is on charge when the unit display shows a battery symbol with 3
bars that turn on and off. It will take approximately 2-3 hours to fully charge. The battery pack is
fully charged when the battery symbol and its 3 bars remain on.
Notes:
•Do not leave your unit connected to the charger when the battery is fully charged.
•Do not leave your charger connected to mains supply when not in use.
Step 2 – Correct garment confirmation
Important:
The correct garment MUST be used for the leg being treated. L is printed on the garment designed
specifically for the left leg. The printed figure of a human also shows the garment positioned on the
left leg (Fig. b). R is printed on the garment designed specifically for the right leg. The printed figure of
a human also shows the garment positioned on the right leg (Fig. c).
Please check now to ensure you have the correct garment for the leg to be treated. If the garment you
have is not for the correct leg, please contact your prescribing clinician or the neurotech®office.
Step 3 – Initial garment fitting
•Sit down with your leg as straight as possible. For the best fit and most effective treatment it is
important to have your leg as straight as possible during garment fitting.
•Place the garment on you leg so that the light blue binding lies just above the kneecap (approx.
0.5cm/ .25”) and the printed Median Line lies along the centre of your thigh (Fig. d).
•Fasten both pairs of straps (Fig. e). For the best fit, fasten the pair of straps closest to the neecap
first. When the straps are fastened the garment should have a comfortable yet firm fit.

SETTING-UP A TREAT ENT
Step 4 – Sizing determination
With the garment still fastened to your leg, sit upright with your knee bent at 90° (Fig.f).
To determine length sizes:
•If the whole garment lies flat along the length of your thigh (Fig. f), you are a Tall fit and must place
the large rectangular electrode within the area marked ‘A’.
•If you have to fold down the top of the garment at the groin (Fig. g), you are a Small fit and must
place the large rectangular electrode within the area marked ‘a’.
To determine width sizes:
There is a line printed on the garment near one end of the straps (Fig. h) to help you determine
whether you are a wide or a narrow fit. If you have difficulty seeing this line, there is also a gap in the
fastening material to help you (Fig. h).
•If the strap does not overlap the printed line, or if you can still feel the gap, you are a Wide fit and
must place the L-shaped electrode within the area marked ‘B’.
•If the strap does overlap the printed line, or if you cannot feel the gap, you are a Narrow fit and
must place the L-shaped electrode within the area marked ‘b’.
Step 5 – Adhesive Electrode Placement
•Remove the garment from your thigh and place it on a flat surface with the white electrode placement
guides facing you.
•neehab XPTM is supplied with a pack of four electrodes. Remove these from their plastic bag.
•Remove the liners from the
patterned side of the electrodes (Fig. i). eep these liners for later.
•Stick the electrodes onto the garment within their respective printed outlines.
•Do not remove the liners from the
black sides of the electrodes yet.
Important:
•Place the largest electrode within outline “A” or “a” depending on your sizing, determined in Step 4.
•Place the L-shaped electrode within outline “B” or “b” depending on your sizing, determined in Step
4.
•The remaining two electrodes should be placed within their respective matching outlines (Fig. j).
•Ensure that all electrodes lie perfectly within the electrode placement guides on the garment.
•Ensure the metal studs are completely covered by all of the electrodes.
•Press the edges of each electrode firmly onto the garment to ensure good adhesion.
•Replacement electrodes are available from your local neurotech®supplier. See page 6.
Your Kneehab XPT is now set up and ready to use.

5.1 Step-By-Step Treatment Guide
Step 1 - Garment Fitting
Using mild soap and water, cleanse the area where you will be placing the garment. The electrodes do
not adhere well to dirt, oil, creams or other cosmetics on the skin. Ensure the skin is dry.
Remove the liners from the
black side of each electrode (Fig. a). Do not dispose of these liners, as
they will need to be placed back onto the electrodes between treatment sessions.
Sit down with your leg as straight as possible. For the best fit and most effective treatment it is
important to have your leg as straight as possible during garment fitting.
Place the garment on your leg so that the light blue binding lies just above the kneecap (approx.
0.5cm/ .25”) and the printed Median Line lies along the centre of your thigh (Fig. b).
Fasten both pairs of straps. For the best fit, fasten the pair of straps closest to the neecap first. When
the straps are fastened the garment should have a comfortable yet firm fit.
Note:
If you are a very narrow fit, the straps may overlap some of the adhesive electrodes. However, for an
effective and safe treatment, it is important that the whole surface of all four electrodes is in contact
with the skin. You can eliminate the overlapping problem by folding the straps inwards at the printed
line before fastening (Fig. c).
Before starting a treatment session:
We recommend sitting with your knee at an angle between 0 - 60 degrees (Fig. d) or lying down with
the leg straight. Before beginning treatment, ensure that all of the electrodes are flat against your
skin.

STEP-BY-STEP TREAT ENT GUIDE
Step 2 – Connect the unit and switch it on
Connect the unit to the garment by plugging it into the garment socket (Fig. e). Switch on the unit by
pressing the On/ Off button for 3 seconds (Fig. f). The unit display will show the programme number
selected, the duration of the programme and the battery status.
Notes:
•When connected to a Left garment the unit will display ‘L’ for 3 seconds at start up.
•When connected to a Right garment the unit will display ‘r’ for 3 seconds at start up.
Please check that your unit displays the correct code for the garment to which it’s connected.
If the unit does not display the expected code, please contact the neurotech®office.
Step 3 – Begin treatment
Begin increasing the intensity (Fig. g). This starts the treatment session and the timer will begin to
count down. As you increase the left or right intensity button you will feel the stimulation increasing
on the corresponding side of your leg. You will also see the intensity level for that side increasing on
the unit’s display. Increase the intensity on both sides of your leg until you feel a firm, comfortable
contraction of the quadriceps. The intensity level ranges from 0 - 99.
Important Notes:
•Typically, you should increase the intensity to the inside of your leg first and to optimise contractions,
the intensity level for the inner thigh should be set at a higher level than the outer thigh. As you
become more experienced using neehab, you will quickly find the levels which suit you best.
•The treatment is delivered in contraction and relaxation cycles. See your Programme Information
Card for more details.
•Changing the intensity at any time will trigger the start of a contraction cycle.

Step 4 – Finishing Treatment & Storage
The treatment session is completed when the counter reaches zero. The unit will beep to indicate this.
Switch the unit off by pressing the On/ Off button for 3 seconds. Should you forget to do this, the unit
will switch off automatically after 20 seconds anyway.
Disconnect the unit from the garment by pressing the buttons on either side of the connector and
pulling the two sections apart (Fig. a).
Remove the garment by carefully peeling the electrodes off your leg. Ensure that the electrodes
remain attached to the garment. Place the garment on a flat surface with the electrodes facing
upward and replace the liners on the
black side of each one. If the electrodes have lifted from the
garment, press the edges back into position.
Close the straps on the garment, ensuring that the electrodes all remain flat. Store the garment, with
the electrodes still attached, on a flat surface in a cool dry place.

7.0 System aintenance
Caring for your Kneehab - Washing Instructions:
Important:
Detach the Control Unit from the garment before cleaning.
You should never let your neehab Control Unit get wet, but it may be cleaned using a soft cloth, lightly dampened in mild,
soapy water. The garment is washable but you must first remove the Control Unit and electrodes. Replace the liners on the
pat-
terned side of each electrode until you are ready to use your neehab unit again. You must always follow the instructions on
the label when washing the garment.
Never machine wash your neehab garment. Hand wash in lukewarm water and NEVER wring to remove water. This
protects the internal composition of the garment from damage.
Do not use any bleach when washing your neehab garment.
Do not dry clean your neehab garment.
Do not tumble dry your neehab garment. The garment should be dried on a flat surface. Do not dry over anything hot
(e.g. a radiator or any other direct heat source). Ensure the garment is completely dry before use. The straps should be
fastened prior to washing.
The neehab garment should not be ironed.
Battery Power / Replacing the Battery
The battery icon on the display will flash when the battery is low and needs to be recharged. After a pe-
riod of time, you may find that the battery will only power your unit for a limited number of sessions, re-
quiring you to charge it more frequently. This is because rechargeable batteries have a limited number of
charge cycles and may eventually need to be replaced.
Should you need to replace the rechargeable battery pack, remove the small rubber plug from the back
cover of your unit (Fig. a), unscrew the back cover and remove it. Replace the existing battery pack with a
new battery pack (Fig. b). Replace the battery cover and rubber plug. You can purchase a new battery pack
by contacting your local neurotech supplier.
