This indicates it is for performance enhancement rather than diagnosis.
No
The device description explicitly lists multiple hardware components including a stimulator, wire set, electrodes, and a charger.
Based on the provided text, the Compex® Sport Plus is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for stimulating healthy muscles to improve or facilitate muscle performance. It explicitly states it is not intended for use in conjunction with therapy or treatment of medical diseases or conditions.
- Mechanism of Action: The description of how the device works involves electrical impulses triggering muscle contractions, which is a physical interaction with the body, not an in vitro test of biological samples.
- Device Description: The components and description of the device align with a neuro-muscular electro-stimulator, not equipment used for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample. There are no reagents, test strips, or other components typically associated with IVD devices.
Therefore, the Compex® Sport Plus is a device intended for physical muscle stimulation, not for performing in vitro diagnostic tests.
N/A
Intended Use / Indications for Use
The Compex® Sport Plus is intended to stimulate healthy muscles in order to improve or facilitate muscle performance.
The Compex® Sport Plus is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. None of the Compex® Sport Plus training programs is designed for injured or ailing muscles and its use on such muscles is contraindicated.
The Compex® Sport Plus electrical impulses allow the triggering of action potentials on motoneurones of motor nerves (excitations). These excitations of motoneurones are transmitted to the muscle fibers via the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration, duration, duration, duration, duration, duration, duration, durati of rest, total session duration), different types of muscle work can be imposed on the stimulated muscles.
The various types of muscle work that the Compex® Sport Plus can impose on the stimulated muscles are able to improve or facilitate muscle performance.
The Compex® Sport Plus may therefore be considered a technique of muscle training.

Program Descriptions:
Training Programs
Compex® Sport Plus provides four stimulation training programs. They correspond to the type of muscle performance the sportsman wishes to improve or maintain. Their claims are clearly restricted to the stimulated muscles.
Each of these four training programs offers five different working levels that enable the amount of work to be gradually increased.
"Endurance" program
The Endurance program imposes on the stimulated muscle a pattern of activities resembling the one that is delivered by the nerve to slow fibers during voluntary endurance exercises. It develops the aerobic metabolism of the stimulated fibers and their capillary supply. It improves resistance to fatigue for long duration exercises of average medium working power level.
"Resistance" program
The Resistance program imposes on the stimulated muscle a pattern of activities resembling the one that is delivered by the nerve to fast fibers during voluntary heavy resistances exercises. It develops the

Compex Sport Plus - K083140/S1
glycolysis metabolism of the stimulated fibers and their capillary supply. It improves resistance to fatigue for short duration exercises of average high working power level.
"Strength" program
The Strength program imposes on the stimulated muscle a pattern of activities resembling the one that is delivered by the nerve to fast fibers during voluntary strength exercises. It develops the cross-sectional area of the stimulated fibers. It improves the maximum strength of isometric and dynamic contractions.
"Explosive Strength" program
The Explosive Strength program imposes on the stimulated muscle a pattern of activities resembling the one that is delivered by the nerve to fast fibers during voluntary rapid strength development exercises (ballistic movement). It develops the strength and/or the contraction speed of the stimulated fibers. It improves the explosive strength.
Other programs
Compex® Sport Plus offers five other programs that are not intended to train muscles. Their objective is to prepare muscle for explosive motion or other training or to facilitate recovery after active muscle training or competition.
"Potentiation" program
The Potentiation program produces the physiological muscle phenomenon known as "Twitch potentiation". A muscle with potentiated fibers has more velocity and reaches its maximum strength more easily and rapidly.
"Active Recovery" program
The Active Recovery program produces muscle twitches at a very low frequency. Those twitches act like a massage and induce an increase of the blood flow and a faster reduction of the lactic acid blood level. It facilitates recovery of the stimulated muscles after active muscle training or competition.
"Recovery Plus" program
The Compex Recover Plus program is a sub-set of the Active Recovery program that produces a very low constant frequency to induce a gentle muscle contraction to increase in blood flow. This program should be used after training sessions and competitions.
"Pre-Warmup" program
The Compex Pre-Warmup program helps muscles to get ready and should be used before training sessions and before competitions.
"Massage" program
The Compex Massage program produces gentle muscle twitches, like a massage, to facilitate recovery from muscle fatigue and to help recover muscle strength after training sessions and competitions.
Substantial Equivalence: When compared to the predicated device, Compex® Sport (011880) and Globus Premium Sport and fitness Muscle Stimulators (K061632), the Compex® Sport Plus has the same intended use. Therefore, Compex® Sport Plus is substantially equivalent to the predicate marketed device, Compex® Sport (K011880) and Globus Premium Sport and fitness Muscle Stimulators (K061632)
