Flexistim IF is an Interferential therapy unit that can be used both in a professional environment and at home to treat a variety of conditions including arthritis, joint pain, sciatica, spondylitis, Rheumatoid arthritis and Osteoarthritis, muscle strains and injuries and provides general pain relief without the need for drugs.

Electrical impulses are sent through self-adhesive electrode pads which are placed on the skin around the area of pain. The impulses use Interferential therapy to combat aches, pains and strains to provide much needed relief when you need it most.

IFT (Interferential Therapy) delivers continuous stimulation deep into the tissue providing relief for deep seated pain and can reduce swelling and inflammation which can often be the source of the pain.

Key Features:

  • 3 preset programmes and 3 user defined programmes enabling you to experiment and save your favourite settings.
  • 60mA Peak to Peak pure sinusoidal carrier wave with constant energy (modified constant current) control and 40mA safety override for home use.
  • Portable and lightweight with belt clip included for mobile use.
  • Clear, backlit LCD screen for ease of use.
  • Removable, rechargeable Li-ion battery for use on-the-go and external mains adaptor for extended use.
  • Flexistim IF automatically starts using the Programme last used and also has a Usage Timer which records the total time it has been used, and the number of uses.
  • Automatic Keypad Lock if no button is used for 10 seconds with settings on manually adjustable programmes which can also be locked.
  • Leads Fault Detector in TENS and EMS modes, where the output level goes immediately to zero in the event of an open circuit.
  • Switching charging adaptor with both UK and EU connections.

WARNING AND CAUTIONS

Contraindications:
1. Do not use this device on patients who have a cardiac pacemaker, implanted defibrillator, or other implanted electronic devices, because this may cause electric shock, burns, electrical interference, or death.
2. Do not use this device on patients whose pain syndromes are undiagnosed.

Warnings: 
1. Do not apply stimulation over the neck or mouth because this could cause severe muscle spasms resulting in closure of the airway, difficulty in breathing, or adverse effects on heart rhythm or blood pressure.
2. Do not apply stimulation across the chest, because IFT currents penetrate deep into the tissue and the introduction of electrical current into the chest may cause rhythm disturbances to the patient’s heart, which could be lethal.
3. Do not apply stimulation over the pregnant uterus.
4. Do not apply stimulation over open wounds or rashes, or over swollen, red, infected, or inflamed areas or skin eruptions (e.g. phlebitis, thrombophlebitis, varicose veins).
5. Do not apply stimulation over, or in proximity to, cancerous lesions.
6. 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.
7. Do not apply stimulation when in the bath or shower. 
8. Do not apply stimulation while driving, operating machinery, or during any activity in which electrical stimulation can put the patient at risk of injury.
9. Consult with your physician before using this device, because the device may cause lethal rhythm disturbances to the heart in susceptible individuals.
10. Apply stimulation only to normal, intact, clean, healthy skin.
11. Using the device directly over metallic implants could cause the currents to focus over a small area, causing tissue burns. If you have metal implants, do not place the pads near, or across the implant, and adjust the intensity with care.

Precautions:
1. Since the effects of stimulation of the brain are unknown, stimulation should not be applied across the head and electrodes should not be placed on opposite sides of the head.
2. The safety of electrical stimulation during pregnancy has not been established.
3. Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conductive medium (gel).
4. Patients with suspected or diagnosed heart disease should follow precautions recommended by their physicians.
5. Patients with suspected or diagnosed epilepsy should follow precautions recommended by their physicians.
6. Use caution when the patient has a tendency to bleed internally, such as following an injury or fracture.
7. Use caution following recent surgical procedures when stimulation may disrupt the patient’s healing process.
8. Use caution if stimulation is applied over areas of skin with less than normal sensitivity.
9. Keep this device out of the reach of children.

Adverse Reactions: 
• Patients may experience skin irritation and burns beneath the stimulation electrodes applied to the skin.
• Patients may experience headache and other painful sensations during or following the application of electrical stimulation near the eyes and to the head and face.
• Patients should stop using the device and should consult with their physicians if they experience adverse reactions from the device.

General Warnings: 
1. Do not immerse any part of the unit in water
2. Do not place the unit close to excessive heat.
3. Do not use any electrodes which are less than 50mm X 50mm.
4. Use only the specified battery: 1x 3.7volt rechargeable lithium battery. The use of any other battery could damage the unit.
5. Remove battery if unit is not used for a long period of time.
6. Do not use the unit while asleep.
7. Do not put the lead wire on, or wrapped around, the neck.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.
