Compare the EMPI 40 Safety Lead Wire and Chattanooga Continuum accessories to find the right TENS lead wire replacement for your device.
Quick answer
If you need a direct cable replacement for an older EMPI TENS unit, choose the EMPI 40 Safety Lead Wire. If you need a remote trigger for a Chattanooga Continuum system, the Hand Switch or Heel/Foot Switch is the right accessory.
What each product does
The EMPI 40 Safety Lead Wire is a replacement cable for compatible legacy EMPI TENS and stimulation devices. It's sold individually and is useful when the original cord is missing, damaged, loose, or causing intermittent stimulation.
The Chattanooga Continuum Hand Switch and Heel/Foot Switch are remote trigger accessories for the Chattanooga Continuum neuromuscular electrical stimulation system. They let you activate stimulation during NMES, TENS, or rehabilitation treatments.
Compatibility is the key difference
The EMPI 40 works with EMPI Focus, Respond Select, EPIX VT, and EPIX XL units. The Continuum accessories only work with the Chattanooga Continuum system. They are not interchangeable.
If you own a legacy EMPI device, the EMPI 40 is your only option here. If you own a Continuum system, you can choose between the Hand Switch and the Heel/Foot Switch depending on your therapy goals.
