Wireless electromyograph

multi-channelfor researchperineal rehabilitation

Overview
Portable wireless surface electromyograph (sEMG) for simultaneous acquisition and neuromuscular stimulation across 1–16 channels. Designed for clinical assessment, rehabilitation and dynamic monitoring with Wi‑Fi transmission and extended battery operation.

Key features

• Simultaneous multi‑channel sEMG acquisition: 1–16 channels.
• Neuromuscular stimulation: up to 16 sites with adjustable current and pulse width.
• Wireless Wi‑Fi transmission for flexible clinical and field use.
• Long‑life lithium battery for extended mobile operation.
• Intuitive interface with real‑time voice and text prompts.

Details
The device acquires and records bioelectric signals from up to 16 channels, capturing data from multiple muscle groups simultaneously. It supports neuromuscular stimulation for multiple areas at once with customizable stimulation parameters. Centered on wireless Wi‑Fi transmission and multi‑channel synchronous acquisition, it features high‑precision EMG signal capture and strong anti‑interference capability. Flexible channel combination modes (e.g. 16+16, 14+2, 12+4, 8+8, 8+2, 8+4) adapt the system to varied sEMG scenarios. The compact, portable design supports dynamic data storage, playback and professional report generation for clinical assessment and continuous monitoring.

Applications
Suitable for rehabilitation therapy, sports medicine, gait analysis, neuromuscular evaluation and home dynamic monitoring where portable multi‑site sEMG acquisition and stimulation are required.

Advantages

• Enhances patient engagement by integrating biofeedback with multimedia game‑based training to improve compliance.
• Integrated electrode cables simplify donning and reduce setup time compared with split‑type cables.
• Modular software with built‑in standardized evaluation protocols reduces learning curve and operation complexity for clinical staff.
