TENS 7000 Digital TENS Unit with Accessories - Muscle Stimulator Machine for Back Pain Relief, Sciatica, Neck, Nerve, Shoulder, Hip, Elbow, Muscle Pain Relief

Worth my money! This Tenz works so well. It is easy to use, and definitely helps eliminate pain.

I highly recommend this TENS unit. My physical therapist uses this one and I figured her endorsement was a good enough reason to try it. After two months of regular use, I'm not disappointed. Best one I've tried.The last one I tried before this had a large display screen that cracked horribly the first time I dropped it, which meant I could no longer use many of the settings because I couldn't see them. Plus the electrodes would work intermittently even though it was brand new.On the other hand, I've dropped my TENS 7000 unit *numerous* times on my hardwood floors due to clumsiness and weak hands from RA, and it still works perfectly. It doesn't have a big display screen, so there's not much that could crack. And the electrodes have worked reliably since day one.Another factor to consider is that on a lot of other units (including the last one I tried) you can accidentally bump the intensity dial or other settings, but on the TENS 7000 all the controls have covers over them so you don't surprise yourself by bumping the intensity up to some insane level and then panicking and scrambling to turn it down or off.The TENS 7000 has numerous signal pattern options for variety so your nerves don't adapt to a single monotonous pattern, and can be set to run for up to an hour at a time. It also has two different channels so you can use four electrodes at once if you want.It takes a 9V battery. When I use it ALL DAY, a battery will typically last me about 3-4 days, and that's actually a LOT of hours when you think about it. Most users don't run them for hours at a time.Tip: It's helpful to wipe the electrodes down with rubbing alcohol after every couple uses or so to remove any oils that can build up, which maintains signal clarity.For anyone who hasn't tried a TENS unit, they really do help with a lot of different types/sources of pain. They work by delivering electrical impulses which disrupt the pain signals being transmitted through nerves, including the sciatic nerve. I've heard feedback from folks with various conditions that cause nerve pain who say they also get some relief from TENS units. Doesn't hurt to try.Besides interrupting nerve pain signals, I've also found that the impulses can often get my spasming muscles to at least partially relax.When I'm focused on the pain in my low back, I'll put an electrode on either side of my spine around L5. When sciatic pain (which I get on my right side) is bad, I'll put one electrode on the right side of my spine around L5-S1, and I'll put the other electrode further down the path of the sciatic nerve on my bum, wherever the pain is strongest in that area. That placement effectively interrupts/dulls the signal for me so that it lessens the intensity of the pain. Often it interrupts the pain signal enough that it only radiates partway down my leg, and on a good day it sometimes stops it from radiating much at all. Left uncontrolled, that pain can bring me to my knees in tears (not exaggerating), so anything that brings it into a tolerable range is hugely successful in my opinion.For me it's helpful about 95% of the time. There are some days where I wear it from the time I get up to the time I go to bed, or sometimes even when I go to bed if the pain won't let up when I lay down. And I'll wear it when I run errands, or just any time I'm doing anything that involves sitting, standing, or moving around. It latches onto to my pocket fairly securely with the built-in clip.I change the impulse pattern every hour when I restart it so my nerves don't adapt and become desensitized to the signal.One pair of electrodes will usually last through quite a few uses, and you can buy replacement electrodes in bulk on Amazon for a reasonable price. I paid $25 for a 48-pack (24 pairs) and I typically go through a couple pairs per week.

Based on another reviewer’s advice I chose this model over the one utilizing AAA batteries, and I am extremely happy I did so.This unit, which runs on a single 9V battery is working much more effectively than even my best home-made versions. Having eaten dozens of honey-coated watch batteries of various sizes, rigging motorcycle batteries with the leads from digital ohm meters, and licking both 110 and European sockets with few beneficial results, this contraption is a real time saver, if even just no longer making weekly trips to Radio Shack for miscellaneous capacitors, transistors, etc. While the lead-core fly fishing line coils connected to a type 31 marine battery did indeed provide some minor neck relief, lugging the 75 pound battery proved to be somewhat inconvenient, especially on bowling night. Enter the TENS 7000 (I realize this sounds a lot like an ad for an upcoming Terminator movie, but that’s really what they call it)Having suffered some extreme issues stemming from the fact I have disks pinching my spine to nearly 100% closed off (I swear I’m not making that up) along with the fact I was born quite young, chiropractors and physical therapists have been a major part of my life for well over 30 years now. While many of them claim it was their manipulations which cured many a stiff joint or mis-aligned spine, I know from experience that TENS therapy truly works wonders. It truly does. With the exception of the time the doc’s assistant came in to turn the rapid-sine machine “off” and accidently turned it from power “2” to “Well Done” and having to peel me off the ceiling, TENS has provided much needed relief from massive muscle spasms in my lower and upper back; eliminated stiffness in my neck; reduced swelling in my neck; as well as made me a very rich man. Well maybe not that last one, but it’s not too late.Anyone who spends time at the chiro knows the joy of TENS therapy, but we also know the disappointment of feeling the power shut down just when it’s starting to feel like it’s working! Sure the doc has other patients in line, but we’re paying for US to get relief- let them wait! With your very own TENS machine at home, there IS no wait, and better yet, as long as you’ve got batteries, there is NO LIMIT to how long you can cook yourself to pain free!! (Disclaimer: I am not a medical doctor. I do have much experience as a PATIENT, and offer only my personal opinion stemming from that experience. If you have a serious problem, please consult a doctor or your local Salvation Army for proper assistance)I read about others who run their TENS constantly, and at full power- setting 8- and achieving good results. Let me tell you, I can take a LOT of pain, and I am running this 9V model at just below power level 3, and it is making my shoulder spaz out so much it resembles Kanye West at a Golden Globes ceremony. I am using my new TENS to relieve a frozen shoulder; after just 30 minutes of low-intensity therapy using the various modes I was actually able to lift my arm over my head for the first time in nearly a year. I swear I’m not making that up. I do firmly suggest that you DO NOT use the unit constantly however, as your body needs time to relax and “calm down” after a session, so based on my decades of experience I would say a total of 2 hours or so per day broken into 30-40 minute sessions will provide you with a quick idea of whether it will work for you or not. Others are obviously suffering different problems however, so you should consult with your doctor (or qualified airline stewardess) to determine what is right for you. That being said, I expect within the next week to be suffering from zero shoulder pain, no more back pain, and full restoration of my receding hairline. While this machine IS pretty cool, I doubt I’ll get down to my desired weight without having used it at least a month, and the cancer will probably require at least another after that. Good thing I also bought rechargeable batteries!The TENS machine is truly very sleek, and extremely well thought out. It is about the size of a walkman; unfortunately in fact, it resembles a walkman SO much that just this morning while out shopping I was hit with rocks by 2 young thugs who told me to “Grow up and join the digital age!” after spotting my TENS conveniently clipped to my Bermuda shorts. Another cool feature is that both the controls for the leads and the modular controls are each protected behind little doors, which prevent accidental changes to the settings while you move about. Very cool, as they are easy deal with when need be. The unit is also lightweight; I would barely know it’s there if it weren’t for the fact my face keeps changing shape as if I’m sticking my open mouth out the car window while traveling in excess of 90MPH on the highway. But darn, it feels so good.Overall I am extremely happy with this unit and wholeheartedly recommend it. Here are the Pros and Cons I have found so far:Pro:Surprisingly low costVERY powerfulLightweightAttractive designMay possibly double as a sex toyVariable modes, wide variety of outputsEasy to program and useMuch more effective than string of holiday lights with tinsel replacing original bulbs then wrapped around bodyCon:Will only partially cook hot dogs at level 6; level 8 burns endsEasily mistaken for Walkman by local thugsDoes not work after being pushed into uncovered cesspoolMay possibly double as a sex toy
