Design and Benefits of Muscle Stimulator    

Compex stimulator is Equipped with unique MI (muscle intelligence) technology that adapts to each of your muscles to provide the most effective muscle stimulation possible while offering greater comfort and better performance. Using MI technology, the Compex SP 4.0 features an MI-SCAN that scans your muscles and automatically adjusts the stimulation based on your physiology. This gives you a more customized experience, ensuring that you are getting the most out of your stimulator.

While an MI-TENS makes it easier to adjust levels of stimulation and optimize results during anti-pain programs. Instantaneously, the MID-RANGE setting will tell you the best level of simulation to use to maximize the effects of the Recovery and Massage programs.

The device also has a built-in monitor that displays the level of stimulation being delivered, which makes it easy to find the right intensity level for your needs. The Compex SP 4.0 is also designed to provide targeted muscle stimulation, promoting improved circulation, flexibility, and range of motion. Additionally, the Compex SP 4.0's sleek design means it is easy to take with you anywhere you go.

How to Use Compex Muscle Stimulator

Body position during stimulation

This position varies according to the muscle group that you wish to stimulate and the program that you are using.

For programs inducing powerful muscular contractions (tetanic contractions), it is recommended to stimulate the muscle isometrically. You should therefore hold the extremities of limbs being stimulated.  This position opposes maximum resistance to movement and avoids any shortening of the muscle during contraction, which would risk causing cramps. For example, when stimulating the quadriceps, you should be in a sitting position with ankles held to avoid extending the knees.

For the other types of programs which do not induce powerful muscular contractions but only muscular twitches or tingling, position yourself as shown on the illustration, maintaining a comfortable position.

Adjusting stimulation intensities

On a stimulated muscle, the number of fibers used depends on the stimulation intensity.
For programs inducing powerful muscular contractions (tetanic contractions), you must use the maximum stimulation intensities (up to 999) while remaining within your tolerance threshold, in order to
use the maximum number of fibers. The progress of a muscle will be greater the higher number of fibers that are worked. During a session it is therefore important to try to increase the intensity every 3 to 5 contractions.
For other types of programs like recovery, massage, capillarization or even muscle pain which only induce muscle twitches, you should gradually increase the stimulation intensities until clearly visible muscle twitches are obtained.
For TENS, Epicondylitis and Tendinitis programs, you should gradually increase the intensities until you feel a tingling sensation under the electrodes.

Scheduling of the stimulation sessions

The question of the scheduling of the stimulation sessions during the week only arises in situations where at least two training sessions are to be done in the same week.

In cases where up to six sessions a week are planned, it is recommended that the sessions be scheduled as far apart as possible. For example, anyone who does three sessions a week should do them at the rate of one session every two days (2x1 rest day and  1x2 days of rest/week). Anyone who does six sessions should do six consecutive days of stimulation with one day of rest.

Above seven sessions a week, it is advisable to group several sessions together on the same day to leave yourself one or two complete rest days without stimulation. Anyone who does seven sessions a week should do five days of stimulation, at the rate of one session per day with one two-session day(s) (with at least a half-hour's rest between the sessions), leaving one rest day. Anyone who does ten sessions a week should preferably do five two-session days (again with at least a half-hour's rest between the sessions), leaving two rest days.

Alternation of stimulation sessions/voluntary training 

The stimulation sessions can be done outside of or during voluntary training.

When voluntary training and stimulation are done during the same session, it is generally recommended that the voluntary training be done first followed by the stimulation. This means that the voluntary training is not done on muscle fibers which are already tired. This is particularly important for strength and explosive strength training.

However, in resistance training, it can be very useful to proceed in the reverse order. Before the voluntary training, by means of stimulation for resistance, a “specific pre-fatigue session” is carried out on the muscle fibers without general and cardio-vascular fatigue. In this way, the voluntary effort on the “prepared” fibers will push the glycolytic metabolism faster and further.

Progression of stimulation cycles

The stimulation cycles are for people who are already accustomed to electrostimulation and want to perform several training cycles.

The cycle logic refers to the workload performed by electrostimulation. Just like a normal workout, one has to to start with an amount of effort then increase it over the course of the cycles. Thus, it is recommended starting with the 1st cycle and going on to the next level when the cycle is finished, normally after 4 to 6 weeks of stimulation based on 3 sessions per week.

It is also important to have reached significant stimulation intensities in sessions before going on to another cycle. At the end of a cycle you can either start a new cycle or do maintenance training based on one session per week.
