Product Overview
The EMG1-4 Wireless Surface Electromyography System is a non-invasive clinical device that captures skeletal muscle electrical activity via skin electrodes in real time. Designed for rehabilitation, sports medicine and neuroscience research, the system provides objective muscle-function data and supports clinical decision-making. Wireless Bluetooth transmission removes cable constraints to improve patient mobility and signal acquisition consistency.

Key Features

• Integrated portable design: sensor and receiver combined in a compact unit for easy handling and transport.
• Up to 8 hours continuous operation with battery-level indicator and low-power alerts.
• Bluetooth wireless transmission providing stable data transfer up to 20 meters.
• Non-invasive multi-channel surface EMG acquisition with real-time monitoring of channel connection status.
• Customizable channel assignment to target specific muscles for assessment and training feedback.
• Built-in visualized 3D human-muscle model for intuitive electrode placement and report generation.
• Real-time low-latency, high-accuracy EMG waveform display with exportable, customizable analysis reports.

Clinical Applications

• Rehabilitation medicine — Objective muscle-function assessment and monitoring for stroke, hemiplegia, cerebral palsy, spinal cord injury and other neuromuscular conditions; progress tracking during therapy and adjustment of rehabilitation protocols.
• Sports medicine & performance — Muscle activation and agonist/antagonist analysis, fatigue and recovery monitoring to inform training load and technique optimization.
• Biomechanics & neuroscience research — Motor control studies, gait and posture analysis (integrated with motion capture/force plates), and research into neurological disease mechanisms.
