Pelvic floor training with the Alonea PelvicTool is done while sitting. The padded seat cushion is placed on a stable, flat stool. The SensorTube is inserted into the cushion and activated by a short press—it automatically connects via Bluetooth to the PelvicTool app on your smartphone or tablet.
When seated, the SensorTube lies directly on the perineum—the area between the anus and the vaginal or penile base. In this area, key pelvic floor muscles, such as the important sphincter muscles, run just beneath the skin. When contracted, these muscles generate measurable pressure that is detected by the sensor and transmitted in real time to the PelvicTool app on your phone or tablet.
The SensorTube measures even the slightest pressure changes caused by the contraction and relaxation of the pelvic floor muscles and converts them into a low electrical signal (Bluetooth Low Energy)—similar to headphones, safe for health.
The PelvicTool app captures this electrical signal and displays the activity graphically, allowing training progress to be seen immediately. This enables targeted, conscious control of the muscles. When you contract the pelvic floor muscles, they shorten, thicken, and harden, creating pressure—and that is exactly what the PelvicTool measures. The measurement is entirely non-invasive: clothing remains on, no probe needs to be inserted. Skin, clothing, and tissue only slightly dampen the signal.
Although all pelvic floor muscles are functionally connected, the PelvicTool primarily measures the effect of the important sphincter muscles or the muscles in the perineal area.
Like any skeletal muscle, pelvic floor muscles become more elastic, stronger, faster, and more controlled through targeted, frequent movement (=training). The PelvicTool supports this neuromuscular training process by indicating whether the correct muscles are being contracted and relaxed. The stimulation of the muscles occurs intrinsically, i.e., by the user themselves.
Experience shows that after just a few training sessions, most users quickly learn to focus on the correct muscles. The feedback on the smartphone or tablet screen makes progress instantly visible—which motivates and improves training efficiency. And—even with interfering effects, the training works. It is simple and suitable for daily use.
Why does the device also show other movements? And why does the training still work effectively?
The pelvic floor forms a network of muscles that are functionally and neurologically interconnected. Isolated activation of individual muscle groups—such as only the sphincter muscles or the levator ani muscle—is hardly possible since they are mostly controlled via the same nerve pathways. Movements of the legs, torso, breathing, etc., also influence the pelvic floor. The pelvic floor does not work in isolation.
For this reason, the Alonea PelvicTool not only shows pelvic floor muscle contractions but also movements of, for example, the buttocks, thighs, or upper body. A typical example is leaning forward, where the labia or base of the penis press more firmly on the SensorTube. Coughing, sneezing, or breathing also causes spikes on the display. It is fundamentally not possible to eliminate all such interferences with holders or similar tools. However, they can be reduced through upright, still sitting and the feedback method.
The real-time biofeedback helps to recognize these movements and disturbances and to consciously reduce them through “learned stillness”—this is the key to effective and largely “isolated” pelvic floor training.
Training effect despite disturbances: The effect on the pelvic floor muscles (strengthening, elasticity, neuromuscular control) still occurs—even if you talk, move, etc. However, the display will be mixed with disturbances, which only slightly affect the actual training.
Only during comparative measurements or for precise measurement purposes—such as determining the muscle’s strength or the speed of contraction and relaxation—must posture and stillness be fully controlled.
