TheraTouch® EX4 Electrostimulation Therapy

TheraTouch EX4: The Command Center for Advanced Electrotherapy

Step into the future of physical therapy with the TheraTouch EX4, an advanced four-channel electrotherapy system consolidating a vast range of treatment options into a single, sleek, and highly ergonomic device.

Intelligent Guidance and Broad Spectrum Therapy

The EX4 is built for efficiency and precision, centering around a brilliant, bilingual, menu-driven touchscreen. This smart interface works like a personal helper, walking clinicians through treatment steps and even showing diagrams for placing electrodes to improve patient results.

The system supports four independent stimulation channels and houses a comprehensive library of waveforms for versatile treatment:

Therapy Category	Waveforms Included
Deep Pain/Modulation	Interferential, Premodulated
Muscle Re-education	Russian, NMS, Biphasic (Symmetrical/Asymmetrical)
Healing/Specialty	High Volt, Microcurrent
Neuromuscular Sequencing	RAAS (Rapid Agonist Antagonist Sequencing)

Unique Clinical Innovation: RAAS

The EX4 introduces the distinctive RAAS waveform—a specialized stimulation designed to mimic the natural, complex firing sequence of healthy muscles. This makes the EX4 exceptionally effective for re-educating weak and inhibited muscles after injury, trauma, or surgical procedures.

Customization and Reliability

Protocol Library: Access eight preset clinical protocols for immediate use, plus the power to store up to 99 customized, user-defined protocols for personalized patient care.
Language Flexibility: The interface can be instantly toggled between English and Spanish.
Assurance: The TheraTouch EX4 is secured by a generous three-year warranty.

That's an excellent feature to highlight, as RAAS is unique to advanced electrotherapy systems!

Here is a detailed explanation of the Rapid Agonist Antagonist Sequencing (RAAS) waveform:

Understanding the RAAS Waveform

Rapid Agonist Antagonist Sequencing (RAAS) is a specialized neuromuscular stimulation (NMS) protocol designed to more closely imitate the way healthy muscles fire during natural movement.

The Problem it Solves

In a healthy body, when you perform a motion (like lifting your foot), the muscles work in pairs:

The agonist muscle contracts (e.g., the quadriceps to straighten the knee).
The antagonist muscle immediately relaxes (e.g., the hamstrings).
The roles then reverse in a fluid, rapid sequence.

Following a surgery or injury, this smooth, reciprocal firing pattern is often disrupted. The brain loses the ability to sequence the muscles correctly, leading to poor coordination, weakness, and inhibited movement patterns.

How RAAS Works

The RAAS waveform works by applying stimulation to a pair of opposing muscle groups (agonist and antagonist) in a precisely timed, alternating sequence:

Sequential Firing: The device stimulates the agonist muscle to contract, immediately followed by the stimulation of the antagonist muscle to contract, and then a brief rest phase.
Mimics Natural Movement: This rapid, reciprocal timing retrains the nervous system to coordinate the two muscle groups correctly. It helps re-establish the neuromuscular communication that was lost due to trauma.
Effective Re-education: Because the electrical impulses mimic the body's native commands, RAAS is highly effective for re-educating weak and inhibited muscles, helping patients regain functional control and dynamic stability faster than standard NMES.

In essence, RAAS is a more sophisticated and neurologically specific form of muscle stimulation, focusing on coordination and sequencing rather than just brute-force contraction.
