Decoding Neuromotor Control and Muscle Activation in Aquatic Environments

This study utilizes Cometa’s wireless EMG technology to precisely quantify lower-limb muscle unloading and neural engagement during underwater immersion. By identifying objective biomarkers in a high-density EEG/EMG setup, the research demonstrates the system’s reliability in capturing high-fidelity data even under external balance perturbations. These results validate the use of Cometa sensors for developing advanced, personalized rehabilitation protocols.

Quantify the Power of Hydrodynamic Resistance

Water is more than just a low-impact environment; it is a tool for targeted strengthening. Peer-reviewed research shows that while buoyancy protects the joints, the viscosity of the water increases core and trunk engagement. Our sensors allow to measure this unique “viscosity-driven” muscle recruitment to maximize the effectiveness of aquatic strength.

Scientifically Validated for Precision Rehabilitation

Research published in the IJERPH confirms that our waterproof sEMG technology captures high-fidelity data even in therapeutic pools. By identifying exactly how water immersion reduces muscle load and spasticity, clinicians can finally move beyond “feel” and base every hydrotherapy session on objective, real-time muscle activation data
