FEATURES
The present invention relates to a wireless ergonomic tri-directional & ambidextrous electronic mouse (WETAEM) for the neurorehabilitation of patients. It is integrated by two drive buttons distributed along its surface, and also comprises three modules for optical sensor of an electronic mouse, one lateral, one lower, and one lateral opposite. The modules for the optical sensor of side and opposite side electronic mouse are activated or deactivated based on the signals sent by a module for tilt sensor A and a module for tilt sensor B, while the module for an optical sensor of electronic mouse lower is activated or deactivated based on the processing through a NOR logic gate of the signals sent by these same modules for tilt sensor A and B, which provides a three-way feature. The present invention is designed so that only an optical-electronic mouse sensor is activated during its operation and communicates wirelessly via a radio frequency (RF) sensor to a device that has a USB port for patient therapy.

APPLICATIONS, BENEFITS, AND USES OF TECHNOLOGY
The use of an ergonomic electronic mouse with certain characteristics for the neurorehabilitation of a patient who has suffered a cerebral vascular accident (CVA) or stroke, is an important and necessary element so that the patient can perform the exercises indicated in the therapy and eventually recover the motor control of their hands. The technology described here is a wireless ergonomic three-way & ambidextrous electronic mouse (WETAEM ), which is intended to help the end-user continue with their therapy in case their hand rotates and it is impossible at that time to return to the horizontal position; original due to the involuntary contraction of the wrist joint due to spasticity. The physical form it has favors an adequate position of the hand when performing neurorehabilitation exercises.

TECHNOLOGY READINESS LEVEL
Experimental tests have been carried out on all the elements that constitute the application at the laboratory level and integration of the basic components to function as a system or technological package (the mouse, its design, and application software). Likewise, there are experimental tests of all the elements that constitute the application at the laboratory level and the basic components are integrated to establish if they work as a system.

In addition, conformity checks of components, drawings, design history, the outline of the product development plan, and an industrial design were carried out.

Considering the above, it is estimated that in this case, the Technology Readiness Level (TRL) according to the NASA/DoD scale is: 4.

MARKET INFORMATION
According to information from Allied Market Research, neurorehabilitation is an advanced recovery treatment method designed for those who have a nervous system-related injury or disorder that helps restore their lost, physician-supervised skills.

Neurorehabilitation devices include noninvasive brain stimulators, brain-computer interfaces, neurorobotic systems, and wearable devices. Neurorehabilitation devices facilitate symptom reduction and improve neurology-related function. This device is most commonly used for physiotherapy and improves the patient's quality of life. To manipulate this device and help the patient improve neurological function, trained professionals are required. There are several types of devices available on the market, such as neuro-robotic devices, wearable devices, non-invasive stimulators, and brain-computer interfaces.

The neurorehabilitation devices market is expected to grow in the forecast period from 2021 to 2028. The market research agency, Data Bridge Market Research predicts that the market will reach USD 1.7 billion in 2021 and reach USD 4.04 billion in 2028 because it has an average annual growth rate (MTCA) of 13. 12% in the period indicated (2021-2028).

The major market players are Bioness Inc. (US), Bionik Laboratories Corp. (Canada), Reha Technology AG (Switzerland), Rex Bionics Ltd (New Zealand), ReWalk Robotics Ltd (Israel), Eodyne (Spain), Neuro Rehab VR. (US), Perfect (US), Hocoma AG (Switzerland), Ekso Bionics Holdings, Inc. (USA),
