What Is an EEG System?

Electroencephalography (EEG) systems are essential tools that record electrical activity in the brain. These systems use scalp-mounted electrodes to detect brain signals and help diagnose neurological disorders. A standard EEG setup includes the following core components:

• Electrodes: Capture electrical activity from the scalp surface.
• Amplifier: Strengthens the brain signals for accurate recording.
• Recording Device: Displays the amplified signals for clinical analysis.

EEG testing is commonly used to diagnose epilepsy, sleep disorders, brain injuries, and other neurological conditions. It is also used in cognitive research and brain-computer interface development. Modern EEG systems now feature wireless technology and dry electrodes, making them more comfortable and efficient for both patients and clinicians.

Cadwell Easy Ambulatory EEG

The Cadwell Easy Ambulatory EEG System is a compact and lightweight solution designed for extended brain monitoring outside of traditional clinical environments. This portable EEG system uses micro-technology with compact flash memory for reliable data storage. Its EasyNet communication platform integrates all system components, while the built-in EEG amplifier ensures accurate signal capture. The system is ideal for multi-day studies and home-based monitoring, offering both flexibility and clinical-grade performance. Patients benefit from greater mobility and comfort, and healthcare providers gain access to high-quality diagnostic data.

What Is an EMG System?

Electromyography (EMG) systems evaluate electrical activity in muscles to assess nerve and muscle health. EMG testing involves inserting fine needle electrodes into targeted muscles to record electrical signals during rest and contraction. This information helps clinicians diagnose conditions such as carpal tunnel syndrome, muscular dystrophy, peripheral neuropathy, and nerve injuries. By analyzing abnormal muscle activity, EMG systems enable precise diagnosis and support the development of effective treatment plans for patients with neuromuscular disorders.

Cadwell Sierra Wave EMG System

The Cadwell Sierra Wave EMG System is a flexible, Windows-based diagnostic platform designed for use in hospitals, outpatient facilities, and mobile testing units. It features a 2-channel amplifier and supports a wide variety of studies, including nerve conduction velocity (NCV), standard EMG, F-waves, H-reflexes, and blink reflexes. The system’s integration with Microsoft Word allows clinicians to generate customizable reports with ease. It also includes the compact StimTroller, which provides quick access to commonly used stimulation functions. Advanced features such as single-fiber EMG, motor unit potential (MUP) analysis, and motor unit number estimation (MUNE) make the Sierra Wave a highly capable and efficient EMG solution.

EMG System Accessories

Accessories are essential for optimizing EMG system performance and clinical efficiency. Footswitches provide convenient hands-free operation. Amplifier cables deliver clean and reliable signal transmission with minimal interference. Headphones offer real-time auditory feedback during testing. These accessories help clinicians streamline procedures and ensure accurate data collection during EMG and neuromonitoring studies.

With a strong focus on innovation and usability, Cadwell’s complete line of EEG and EMG systems continues to set the standard for neurodiagnostic technology. Whether used in routine evaluations or specialized research, Cadwell products deliver consistent performance and clinical value across a range of diagnostic applications.
