  • From Yo at 8/13/2015 9:45 AM
    • Recovering from an incomplete spinal cord injury at T12 level lost movement in both my legs for a couple months. I workout and stretch everyday and have been slowly regaining movement but lost most of the muscle in my legs. I have noticed an increase in muscle over the past 6 weeks or so but recovery has been slow and I exhaust quickly during my workout. I am interested if a unit like this would be beneficial in my strength and recovery efforts.

      Thank You
    • Yes this would be beneficial to you. You can use it on your off days for Recovery and to suppliment your workout
  • From jose at 8/9/2015 6:46 AM
    • Hi, I want to to know the differences between the Compex gama and the Cefar Compex gama. Because I´m looking for both but the cefar compex I think it has more programs and also screen pictures where you sholud place the paths.

      Please tell me if I´m correct.

      Thanks for your help
    • Jose
      We do not seel those products in the USA so you will need to go to the EU websited to get information on those particular models.
  • From Sam at 8/8/2015 5:54 PM
    • Are you able to use the complex while working out. Say using it while doing body weight squats or lunges?
    • Sam
      The ansewer to your question is yes
  • From Angie at 8/5/2015 9:35 AM
    • I was just curious how high this machine goes? I've used the Sport Elite so I just wanted to know high high it goes in comparison to that.
    • Hi Angie,

      The Edge will run at the same frequency and intensity as the Elite, but it does not have the same number of programs as the Elite. The Edge only has the Resistance, Active Recovery, and Endurance programs.
  • From Patrick at 7/25/2015 10:05 AM
    • I read description of item. How does it tone muscles and what does it do to tone the muscles? Thanks.
    • For toning, we recommend the using the Resistance program. This program targets both the slow and fast-twitch muscle fibers to help build muscle size and density.
  • From TrueChick at 5/18/2015 7:45 PM
    • Does this come with like, a guide to sensor placement and settings for muscle groups, or are we left out there floundering?
    • Hello,
      Yes the Compex Edge will come with an Electrode Placement Guidebook to help you with pad placement. There is also many resources on our website for assistance with pad placement, and training programs, see the links below:

      Also, here is all that is included when you purchase the Compex Edge:

    • Hi, im a 26 years old male and i had a brachial plexus injury a year ago on my left side and lost movement on my biceps and deltoid, 4 months ago i had a neurotization surgery and i was told for the recovery procedure to be enhanced i need to acquire one of your electrostimulators but i have no idea wich one to choose.... sorry for my bad english btw
    • Jorge
      Our Compex Units are not designed for rehab of unhealthy tissue, only healthy tissue. We do have a division of our company that does sell units used in rehab after surgery and injury. The division is called Empi and the units require a doctor's prescription. To find a Empi sales rep in you area please copy and paste this link.
  • From Ali at 4/16/2015 5:21 PM
    • Hello. I have had two hip replacements over the last 2 years. I am now dealing with weakness in my right hip/quad which is restricting my workouts. I currently Crossfit (modified) 2-3x a week. Which model would be ideal to help my recovery after a workout and help build back my muscle strength?
    • Ali
      The edge unit has 3 programs
      2 Strength: Resistance/Strength
      1 Recovery: Active Recovery

      You can use the Recovery program after workouts and use the strength programs on off days in the gym
  • From Mike at 4/7/2015 6:06 AM
    • Hello,

      I'm an active CrossFitter and have been using a friends Marc Pro here and there to help with recovery/injury. I'm looking to get my own, but trying to decide between the Marc Pro and the Edge. I'm mainly looking at it for recovery. How does the Edge compare to the Marc Pro?
    • Mike
      Since the MarcPro is not a product of ours I had to look it up online to see what it specifically does. The main difference is that the MarcPro is only for muscle recovery where the Compex edge has 3 programs Strength, enderance and Active Recovery. The Compex will accomidate bigger muscle groups by using 4 leads and you can two different body parts at the same time because of the 4 leads, compared to the Marc Pro which only has 2 leads. Our unit offers more for less money.
  • From Johnm at 3/16/2015 1:54 AM
    • I have mild and currently controlled rheumatoid arthritis. I have been to a chiropractor and have had ems applied and I have used tens units at home. I like what ems units do for me. I have pain in my hands and mild bouts of tendonitis and I am a factory worked assvling radiators. I have had some relief with tens units. I want something better to help me get through the day more functionally and drug free. Is there a device in your lineup that can make that difference?
    • John
      The compex is not a pain reliever, it is used to help with strengthening muscles. The Compex is not the correct typ of stimulator. You would be interested in one of our Empi products. Copy and past this link to locate your local Empi sales rep to get information on our Empi Continum
  • From Martin at 2/22/2015 3:57 PM
    • Hello, I train 3 times per week (Crossfit) and I would like the compex to gain mass and for recovery, to complement my workout and diet. Would the edge be suitable for me? Would i get quicker results? How should i use it during my workouts? Thank you.
    • Martin
      You can definatley use the Edge for what you want to accomplish. The unit should be used in conjuction with your strength training program. You can use it on off days or use it on legs when you are doing upper body in the gym, and vice versa. The Edge only has two strength programs endurance and resistance, this it also has a recovery program for after workouts

  • From Daryl at 1/15/2015 7:27 AM
    • Hi, I broke my left talus and am currently in recovery mode. I need to increase circulation through the talus to my foot and back. Not sure what muscles are in the feet but would your product be able to assist in this effort? Which product would be best? Where would I place the electrodes to achieve this?

      Thank you
    • Daryl
      The Compex Units are NMES muscle stimulators not IFC, they are used for training and muscle strengthening. They do not help with the healing process. If you want to strengthen the muscles in your calf then you can use the Compex, any model. For recovery and increasing circulation you may want to look at interferntial treatment.
  • From Juan at 1/14/2015 6:39 AM
    • Hi, does any compex works for building muscle? Not by being seated on the sofa... but by making exercises at the same time you have it on.
    • Juan
      You can use any of the Compex models to build muscle while doing activities
  • From Johnny at 11/11/2014 2:23 PM
  • From Patrick Kearney at 11/10/2014 7:35 PM
    • Is there a setting to where I can turn down the intensity and leave it running for 2-3 hours? The goal would be just to keep my leg loose as I have a strained hamstring that tightens up throughout school and gives pain.
    • Patrick
      There isn't any programs that run that long, 20-30 minutes will be the max. This is not a TENS unit it is NMES. The closest thing to what you are describing would be the Massage program on the Elite unit
  • From Lene at 11/10/2014 10:02 AM
    • How many Hz are the three different compex models Worning on?
    • Lene
      The differences in Hz depends on the program used. Here's a breakdown in the different models and what programs they have:

      Sport Elite Unit - Training Programs (9)
      (2) Warm-up Pre-Warm Up / Potentiation
      (4) Strength Endurance / Resistance / Strength / Explosive Strength
      (3) Recovery Active Recovery / Recovery Plus / Massage

      Performance Unit - Training Programs (5)
      (1) Warmup Pre-Warm Up
      (3) Strength Endurance / Resistance / Strength
      (1) Recovery Active Recovery

      Edge Unit - Training Programs (3)
      (2) Strength Endurance / Resistance
      (1) Recovery Active Recovery

      For the Hz in each program please refer to the Compex website for description of each program and which muscle fibers it effects:

      Basic Principle of NMES

      Neuromuscular Electrical Stimulation (NMES) - also referred to as Electrical Muscle Stimulation - is a safe and effective way to optimize workouts and exercise more muscle fibers in less time. NMES technology reproduces the body’s natural process of voluntary muscular contractions with high-intensity “optimal” electrical impulses.
      Generally, muscle tone and strength are developed through exercising the muscle physically. The process starts by the brain sending a signal through the spinal cord and to the nerves of the muscle. This signal tells the muscles to expand or contract. As the muscles continue to expand and contract, the tissue begins to break down. Once your body stops contracting the muscle, it will automatically start building the muscle tissue back up. The muscle will also make the tissue stronger to better face contractions in the future.
      With NMES, instead of your brain sending a signal to your muscles through the spinal cord, the NMES machine electrically stimulates the nerves attached to the muscle at the motor point. Once the nerves are stimulated, they cause the muscle to expand and contract, much in the same way as conventional exercise. This allows those who are unable to exercise in the traditional manner still gain greater strength and muscle mass. NMES controls the muscle work, and the quality and quantity of this work will depend on the programmed parameters and the intensity used (assuming that the electrodes are properly placed).
      The basic tool to make the muscle work is the electrical current pulse. Its role is to trigger off excitation at the nerve fibers (motor neurons), which control the muscle fibers. The excitation of the motor neurons is transmitted, via the motor plate, to the muscle fibers which produce an elementary mechanical response. This mechanical response consists of a single twitch of a very short duration, 0.1 seconds maximum. Each time the pulse is repeated, the excitation is repeated and so is the muscle twitch.

      The five (5) essential parameters are as follows:
      1. Electric Pulse, which triggers off the excitation of the motor neurons.
      2. Pulse Frequency (PF), which means the number of repetitions per second of the electric pulse during the contraction.
      3. Duration of Contraction (DC), which means the time during which the muscle contraction is maintained.
      4. Duration of Rest (DR), which means the rest time between 2 successive contractions.
      5. Number of Repetitions (NR), which means the number of times the “contraction-rest” cycle is repeated.
      The electric intensity is the final parameter which is not involved during the programming stage, but only during the moment of the application of the NMES. The number of working fibers which do the programmed work under the five parameters listed above, depends on the level of intensity. The higher the intensity, the stronger the contraction. However, the fibers don’t contract more strongly – there are simply are more fibers doing the same work.
      Electrical Pulse of NMES
      The Electric Pulse is the basic tool of NMES. Its quality will definitively influence the NMES’ message sent to the motor neuron. It is fundamental to have the best possible electric pulse. Unfortunately for the user, the pulse cannot be seen. This is the reason why so many stimulators of poor quality can be found in the marketplace. These are inefficient and/or dangerous.
      The high quality electronic components of the Compex units produce an optimum pulse. It fulfills both criteria of efficiency and safety plus comfort requirements. On one hand, the pulses must be really powerful to be efficient and allow to recruit a maximum number of muscle fibers. On the other hand, this power must be absolutely controlled to prevent electricity pain and risk of burning.
      The characteristics of the Optimum Pulse are fixed – it is a rectangular biphasic impulse. The rectangular form must be as pure as possible. The symmetry of the two rectangles must be absolutely perfect to achieve a null electrical average and thus to avoid any risk of burning.

      Pulse Frequency of NMES
      The pulse frequency (PF) is the number of pulses repeated in one second. This frequency is expressed in Hertz (Hz) and it is programmed between 0 and 120 Hz. If the PF is 10 Hz, it means that the pulse is repeated 10 times in 1 second and the muscle fibers are exhibiting 10 twitches in 1 second.
      However, at 25 twitches per second, there are so many twitches in a short period of time that they can no longer be individually separated. It goes so fast that the first one has no time to end before the next one starts. Thus, an adding up of the twitches occurs. Instead of individually separated and successive twitches, there is a fusion of the twitches.
      The fusion phenomenon of twitches is called tetanization or tetanic contraction. The more marked it is, the greater the strength developed and the higher the work per unit of time. In fact, the strength developed by the muscle fibers is much greater with a tetanic contraction at 25 Hz than without tetanization at 10 Hz.
      At a frequency of 50 Hz the strength would be still greater. The higher the PF, the greater the strength developed and also the higher the rate at which the increase in strength is developed at the start of the contraction. It can be readily understood that a strength program requires the use of a high PF whereas an endurance program requires a lower PF. Within certain limits (see below) we can observe the following principle: at the recruited muscle fibers, the higher the PF, the greater the tetanization, strength, rate, work and power, but fatigue also develops faster, since the power and work are high.

  • From Chris at 11/1/2014 8:09 PM
    • At the old age of 40+, I have really pushed my training to new levels and begun competing in triathlons. However, with the amount of biking and running I do, I occasionally run into problems with my lower legs - strain, shin splits, etc. Would the Edge help with my recovery time if/when I do suffer from lower leg pain? Would it help with the tenderness I am feeling after long workouts?

      In the past, I have visited a Physical Therapist and sometimes have been adjusted by a chiropractor.

      Mostly I am a casual athlete, so I don't need anything robust - just an extra boost on my recovery when training log distances or training on biking and running together.
    • Chris
      The Edge does have a recovery program to clear lactic acid out of the muscle after a workout and help recovery.
  • From Mell at 10/30/2014 5:18 PM
    • Hi, im debating which compex will suit me best. I suffer from tennis elbow and carpel tunnel due to paddling canoe or supping. Can it be use for the fore arm?
    • hank you for your question. The Compex is designed to be used on healthy muscle tissue in in conjunction with a fitness program. If you are looking to strengthen the muscle sin your forearm you could use the Edge. the Edge contains a resistance and endurance program which would be appropriate for your needs. If you are looking to use the product on larger muscles and would like additional programs such as the explosive training, you would want to go with the Sport Elite. Please feel free to call with any additional questions you may have. 800-553-6019
  • From susan at 10/10/2014 7:42 PM
    • HI, I am interested in purchasing one of your units, but am not sure which would be the best option for me. I used to work out 6 days a week, and although I am by no means a bodybuilder, I was in pretty good shape. however, late July of this year I became ill and was pretty much bed-ridden up until now. I really want to recover my muscle tone as I feel I have lost quite bit of it along with my weight.
      Which unit can help me regain my muscle tone, and maybe help build up my muscles too, as I will start exercising again, easy at first until I get back where I was. My main focus areas are my back legs, glutes, triceps, abs/obliques. Can any of these units achieve this, and if so, which one?
    • Susan
      The Performance has 5 programs
      Performance Unit - Training Programs (5)
      (1) Warmup Pre-Warm Up
      (3) Strength Endurance / Resistance / Strength
      (1) Recovery Active Recovery

      With the three different programs for strength you should be able to achieve your goals. The endurance program works slow twitch muscle fibers and the Resistance and Strength programs will work the slow twitch for muscle toning and muscle growth
  • From John at 10/5/2014 4:40 PM
    • What setting would be best for high volume-hypertrophy training?
    • John
      The Edge has two strength programs, 1) Endurance and 2) Resistance. The resistance program targets both Slow & Fast Twitch muscle fibers. Increases tissue hypertrophy, strength and density. Improves toning and definition of desired muscle groups.
  • From Alex at 8/16/2014 2:29 PM
    • Will this Compex Edge help increase your vertical jump ?
    • You are going to need strength especially explosive strengh to increase a vertical jump, the Performance or the Sport Eliete would be better suited for this
  • From Gcic420 at 8/2/2014 10:09 PM
    • I Crossfit 5-6 days per week, will this help with quicker recovery for muscles? Espcially legs after heavy squat days etc? Also, I'm recovering from a herniated disc in my neck, when I go to PT they do muscle stim on my traps and mkc can I use this for same purpose? If so what model? Thanks.
    • The Compex Edge does have two recovery programs so you can use it in conjuction with your Crosfit. The unit is not a pain control unit so you cannot use it in the same capacity as the stim that is being sued at your PTs office. It is not a TENS unit.
  • From Oscar at 6/30/2014 2:53 PM
    • Hello,

      I am interested in purchasing the Compex Edge. I would like to know if this would benefit me and if so how. I am recovering from a fractured fibula and a fractured Tibia. I underwent surgery immediately after i sustained the injury. I have a rod and pins in place. It has been a little over a month and obviously i've lost a lot of muscle mass from both my calf and my thigh. I am a soccer player which of course this is how I received my injury while playing. I am looking for anything that can benefit me. If you guys believe this product can help me please let me know if so and how or if any of your other products will better suite my needs. Thank you for your time it is much appreciated.

    • Oscar
      The compex can help build muscle in addition to your normal exercise routine. It is best used in conjunction with a rehab or exercise program. The edge has three programs, two strength programs and one recovery program. It should help you with getting back into shape for soccer
  • From Joshua at 6/25/2014 10:06 AM
    • Hi I am in boxing and I need to work on enhancing my power and endurance, and stamina so that I can last longer, punch harder, and take more punishment then the average light weight can dish out
      Would the Compex Edge be good for this job cause it's the cheapest of the compex sport devices or do I need to buy one of the more expensive ones
      also would I have even more energy if I started using a Compex Sport and taking Keybiotics
    • Joshua
      Here is the break down on each unit and what programs they have.

      Sport Elite Unit - Training Programs (9)
      (2) Warm-up Pre-Warm Up / Potentiation
      (4) Strength Endurance / Resistance / Strength / Explosive Strength
      (3) Recovery Active Recovery / Recovery Plus / Massage

      Performance Unit - Training Programs (5)
      (1) Warmup Pre-Warm Up
      (3) Strength Endurance / Resistance / Strength
      (1) Recovery Active Recovery

      Edge Unit - Training Programs (3)
      (2) Strength Endurance / Resistance
      (1) Recovery Active Recovery


      Endurance Targets Slow Twitch muscle fibers. Increases capillarization of the muscles and helps develop the oxidative power of the tissue to express strength over time. Particularly effective for the stabilizing muscle groups and tissue activation during functional movement patterns.

      Resistance Targets both Slow & Fast Twitch muscle fibers. Increases tissue hypertrophy, strength and density. Improves toning and definition of desired muscle groups.
      Strength Specifically targets Fast Twitch muscle fibers. Increases pure contraction and taxes the tissue at maximum power. Provides option for muscle group contraction if injured or training tapering
      demands restrict participation in weight room or isometric strength activities.

      Explosive Strength Produces short bursts of contraction targeting “large muscle group” Fast Twitch fibers as similarly used in sprinting, jumping and explosive movements. Maximum tissue contractions with longer rest in between bouts.
      * All of these programs provide efficient muscle contraction with less stress on joints and tendons and virtually no cardiovascular or mental fatigue.

      For a boxer you need explosive strength to increase the power of your punches so the Elite might be best. I hope this information helps.
  • From Leo at 5/26/2014 6:58 AM
    • I dont have time for gym , if i buy the compex edge and i uset for build muscle and a clean diet too , i can get really good results? i want to gain muscle. Thank you.
    • Thank you for your question. The Compex is designed to be used in conjunction with a training program to provide optimal results. The Compex alone cannot provide most likely, will not give you the results you are looking for.
  • From Jay at 5/21/2014 7:17 PM
    • I plan on using this EMS with my plyometric training. I'm not looking for a product that necessarily does all the work will I sit by, but the product with that simply would activate my fast twitch muscles DURING my exercises. I desperately am trying to save my money so I don't want to buy something with extra settings that i don't need. So which compex product should I buy and which setting should I use during my Plyo training?
    • Jay
      Plyo training is an explosive activity so you will want to use the Explosive strength program that is only available on the Sport elite. If you go to and purchase the unit and use the discount code CPX0531 it will give you 25% off the unit. That is $212 off the price.
  • From ben f at 5/14/2014 7:26 AM
    • whats the highest intensity level (ma)?
    • The highest intensity is different for everyone depending on their tolerance, but the machine intensity will go up to 100
  • From leo at 5/8/2014 8:34 AM
    • Hi i can gain muscle using the compex edge wit a diet plan and cardio? Only doing the compex edge , cardio and a diet plan?
    • Leo
      The compex Stimulators are ment to be used in conjuction with a workout plan. Although you can use them with out gettin into the gym and lifting wieghts, the mucle building will be very minimal.
  • From eking at 4/14/2014 12:36 PM
    • Comparing both the EDGE and PERFORMANCE units, which of them would achieve muscle hypertrophy at a quicker rate?

      In the PERFORMANCE unit, there is a mode called STRENGTH, will the strength program increase the results (tone, muscle size) quicker than the regular programs with the EDGE and what will it gravitate you more towards, a lean ripped beach body or a body builder?
    • The Performance Unit has 3 programs for strength: Endurance, Strength and Resistance. The Edge only has 2 Endurance and Strength. The unit is to be used in conjuction with a wieght training program so just using the unit alone will not build muscle size and the more you work out depends on how big you will get along with your normal genentic make up
  • From Ace42 at 4/12/2014 6:57 PM
    • I do training on the side but I wanted to work my core and develop and tone my abs as well as work on increasing my bicep and triceps size and strength, is the Edge model ideal?
    • The edge has two strength programs: Resistanc eand Endurance and then a Recovery program. That should be sufficient
  • From Keith at 4/6/2014 1:52 AM
    • It sounds like the idea is to use the compex in conjunction with a workout. It is not to be used on its own for building muscle mass or strength. Am I on the right track?
    • Keith
      Yes you are correct it should be use on days you do not work out or go to the gym, except for the recovery programs
  • From ZOMI at 4/5/2014 3:36 PM
    • i do workout twice per week, can this model can helpm me to tone my buttocks, and legs ?
    • you can use the Compex on days you do not work out to supplement you fitness program. Strength programs are like going to the gym and lifting wieghts
  • From HurtingHammies at 3/5/2014 8:35 PM
    • Hi,
      I am a long distance runner who overtrained and have upper hamstring injury (near gleutes) in Feb 2013. Physical therapy helped but being an year old injury, my glutes and upper hamstring still tight and possibly with scar tissue. I have slowly started running 2-3 miles again and want to get back to running long distance again (ultra). Do you recommend compex for improving blood circulation in high hamstring and glutal areas? Which model is good for me?
    • The compex units will work alongside your training regime to help strengthen the muscles with a variety of programs. With a runner you want to increase strenght and endurance. the Edge has 3 programs two strength(Endurance/Resistance) and Recovery. The Performance has 5 programs: 1. Warm-up, 3 strength programs (Endurance, Resistance and Strength) and a Recovery program. The Performance Unit would give you more programs to use
  • From Nicole at 2/17/2014 2:21 PM
    • What programs does this offer (warm up, sport, pain relief, Cross training, Conditioning, recovery)? I am specifically looking for Rehabilitation Disuse atrophy??
      Potentiation: Optimizes muscle potential before a workout or competition. Especially effective for sports requiring speed and velocity. Should be used 10 minutes prior to activity.

      Endurance: Targets slow twitch muscle fibers. Increases capillarization of the muscles and establishes a working regimen for developing the oxidative power of the endurance muscle fibers.

      Resistance: Targets both slow and fast twitch muscle fibers. Builds muscle size, strength and density.

      Strength: Targets fast twitch muscle fibers. Increases sheer strength and works the muscles at maximum power with less risk of injury to joints and tendons and virtually no cardiovascular or mental fatigue.

      Explosive Strength: Targets fast twitch fibers located in large muscle tissue. Improves jumping, sprinting or “explosive” muscle movements.

      Active Recovery®: Produces a muscle twitch. Clears lactic acid, increases blood flow, promotes muscle relaxation and enables a faster recovery.

      Recovery Plus: Produces a muscle twitch. Runs at a lower frequency and clears lactic acid, increases blood flow and promotes muscle relaxation when muscles are fatigued after a vigorous workout or competition.

      Pre-Warmup: Produces a muscle twitch. Runs at a low frequency and increases blood flow and oxygenates the muscles prior to a workout or competition.

      Massage: Produces a muscle twitch. Runs at the lowest frequency possible to relax muscles that are severely fatigued after a workout or competition.

      The Strength program used in conjunction with a training program will build muscle size. If you have any further questions please dont hesitate to call us.

    • I am recovering from a shoulder injury and am unable to keep a steady work out on my pecs will this model help.
    • John
      The Edge has one resistance program for building mucle and one endurance program, so you should be good with this unit

    • I am 84 years old and I am losing muscle strength in my lower and upper legs.Would the Compex Edge stimulator help reverse the process and regain muscle strength in my legs? I exercise almost daily by walking and riding my training bike.
      Thanks for an early response.
    • Werner
      The compex has been FDA approved as a neuomuscular electrical stimulator. The Edge has one program for resistance that will help build muscle in the legs. So this could help you in addition to the exercise you already do.

    • Hello,

      I work out in the gym and maintain a good diet. My issue is I have one pectoral bigger than the other. My idea was to use this machine to build the smaller chest muscle while resting the other to even out.

      Do you think there would be any benefit in this or it could be achieved with your system?

    • Thank you for your question. The Compex is designed with the ability to build muscle mass. However, if you have a significant difference in size, it may not be able to build it to the level of the other. You may want to talk to your physician for more assistance in the muscle development and if Compex may be an option.
  • From Jackie Sevy at 11/11/2013 5:11 PM
    • Does de Compex Edge have the Rehabilitation category as the Sport Elite Compex?
      Or do you still carry the Sport Elite Compex?
      Thank you
    • Jackie,
      The Edge has the Active Recovery program setting. This produces a muscle twitch, clears lactic acid, increases blood flow, promotes muscle relaxation and enables a faster recovery. We do still offer the Sport Elite which has 9 programs including the Active Recovery and the Recovery plus. The Recovery Plus produces a muscle twitch, runs at a lower frequency and clears lactic acid, increases blood flow and promotes muscle relaxation when muscles are fatigued after a vigorous workout or competition. Thank you for you question.

    • Hi, I had a surgery in my back a month ago and I lost some muscle.
      I just want to know which of the complex I can use for recover the muscle after a surgery.
    • Fernando,
      The Compex is designed to be used in conjunction with a training program to enhance muscle performance. It is an over the counter unit sold without prescription to work with healthy muscle tissue. There are cases in which doctor may prescribe a unit for muscle recovery and strengthening. Each of our 3 units sold in the USA have the endurance, resistance and active recovery programs that your doctor may recommend, and the Sport Elite includes a recovery plus program. The programs are outlined on the following web page It would be recommended you speak with your physician to find the Compex unit that may work best for you. Thank you for contacting DJO.
  • From Andrea at 11/1/2013 4:26 AM
    • Hi, I'm recoverying from a hip replacement surgery and my doctor recomended me to buy compex one. where can I buy it? Do you recomend another one?
    • Andrea,
      The Compex Edge has strength and endurance settings that could be used around the hip to help with recovery. The other Compex units (Performance and Elite) may have more programs than you would need or use; including Potentiation, strength and explosive strength. I would speak to your doctor more about his prescription/protocols as far at duration and frequency that you are to use the unit keeping in mind your parameters may vary from the suggested use.
      Thank you for your question. Please contact us for any further information you may need.

    • Im training 5 times a week. But i want an extra help do i need this product or another one to tone my muscles.
    • Hello, Jose -

      This product is not designed to tone muscles. I'm not sure of a muscle stimulator that does this as most are used for muscle recovery from workouts and warmup for activity.

      If you have further questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!
  • From dan at 12/11/2012 4:30 PM
    • will this unit also serve as a tens unit and how long do the battery last and can it run on the power cord when charging if the battery runs down and you need to use it thanks
    • Dan,
      No this will not act as a TENS unit, it is an NMES unit. The wavelengths are different. The battery should last for several years. Unfortunately, no it can not be used with the cord only the battery.
