Mytrex Elexa Handset

Mytrex Elexa Hand is a grip training device featuring Electrical Muscle Stimulation (EMS) technology, specifically designed to progressively, safely, and comfortably strengthen the hand and fingers. It works on the three key functions of the hand—grasping, pinching, and holding—to improve strength, coordination, and independence in daily activities. It is particularly useful for older adults or those with reduced mobility who wish to maintain their hand function, athletes who need to optimize grip and endurance, and users undergoing rehabilitation who require controlled training without overstressing their joints. Its compact and minimalist design aligns with the Japanese philosophy of precision and efficiency, integrating advanced technology into a simple-to-use format.

Elexa Hand uses low-frequency EMS (25 Hz) to activate intrinsic and extrinsic hand muscles through gentle, controlled electrical impulses. This technology allows muscle work without the need for intense gripping efforts, reducing the fatigue and pain associated with traditional exercise using resistance bands or balls.

The device has 5 adjustable intensity levels, making it easy to adapt the session for beginners as well as more experienced users or those with specific rehabilitation needs. Dual control allows for separate intensity adjustment for each hand, offering more precise and personalized training. Thanks to its simple interface, with a clear LED screen and a single button for power and adjustments, operation is intuitive and accessible for all types of users. Stimulation automatically stops if contact with the hand is lost for more than 2 seconds, adding an extra layer of safety to use.

Mytrex Elexa Hand is designed to globally improve hand function. By working on gripping, pinching, and holding, it helps strengthen the force needed for daily tasks such as opening containers, carrying bags, handling utensils, or using electronic devices more comfortably. It is also an effective complement for athletes in disciplines such as climbing, tennis, golf, or calisthenics, where grip strength and endurance are crucial.

In rehabilitation or physical therapy contexts, the device offers progressive and controlled training, suitable for accompanying recovery processes under professional supervision. The low stimulation frequency and the ability to adjust the intensity minimize the risk of overuse, making muscle work effective yet gentle on joints and tendons.

The Elexa Hand features a compact circular design, with an approximate diameter of 68 mm and a weight of 107 g, fitting comfortably in the palm of your hand. It is made of ABS combined with soft-touch TPU, providing a pleasant feel and good grip during use. Its silent operation allows it to be used in shared environments without disturbance, whether at home, in the office, or while traveling.

Inside, it integrates a 350 mAh (3.7 V) lithium-ion battery that offers up to 68 hours of use per charge, a remarkable battery life for a daily training device. The estimated charging time is 2 to 3 hours via the included USB cable. The automatic timer turns off the device after 15 minutes, setting standard sessions and preventing excessively prolonged use. All of this makes it a practical tool, always ready to accompany your hand muscle care routine.

Using the Mytrex Elexa Hand is simple: just place the unit in the center of your palm with the buttons facing up, press and hold the power button for about 2 seconds, and select your desired intensity level with the + / − controls. Each session lasts approximately 15 minutes and stops automatically; if contact with the hand is lost for more than 2 seconds during the session, the device interrupts stimulation. It is recommended to start with low intensities, especially for sensitive users or those in rehabilitation, and gradually increase based on sensations and set goals.

For safety, the manufacturer notes contraindications for people with pacemakers or other implanted electronic devices, as well as in certain clinical cases where EMS may not be advisable. In cases of pregnancy, epilepsy, or other relevant conditions, it is advisable to consult a healthcare professional beforehand. The device comes with the main unit, a USB cable, and a user manual, which details the warranty conditions and applicable certifications according to the brand's policies.
