美國Noraxon??
在NORAXON所有表面肌電測量儀器里，均包括具國際專利的信號處理技術(shù)。NORAXON獨有的信號處理技術(shù)能克服干擾或噪音（稱為后生現(xiàn)象），NORAXON被公認為全球肌電系統(tǒng)標準。
Since 1989, Noraxon U.S.A. Inc. has been a leader in manufacturing and distributing high-end tethered and wireless surface and fine-wire electromyography (EMG) instruments, software, sensors and accessories. Our technology is used by professionals monitoring the performance of athletes, researchers and clinicians specializing in muscle injury and rehabilitation, and for the study of ergonomics in the workplace and product design.

Noraxon's patent-protected instruments are designed with a unique amplifier technology that eliminates external noise and artifact to capture clean, reliable and repeatable EMG signals. Noraxon's hardware does not contain "notch-filtering", resulting in the most reliable surface EMG (SEMG) instrumentations for dynamic muscle function.

Noraxon offers a full line of SEMG products, from a two channel handheld unit, data analysis and acquisition software, to an elaborate 32 channel telemetry system. A wonderful advantage of Noraxon's equipment is its capability to interface with the most popular motion measurement systems on the market as well as other commonly used measurement devices such as goniometers, foot switches, strain gauges and force plates. A recent addition to the complete line of EMG products has been an extensive array of biomechanical sensors.

By providing superior products, service and support, Noraxon continues to make a world of difference.
