DTS Footswitch Sensor
DTS Footswitch 2-FSR/4-FSR & Insole Sensor
for Noraxon TeleMyo DTS System
- 2 - 4 small foot switch sensors per foot/side/lead
- Marks Heel strike and Toe off events during gait
- Adjustable sensitivity
- Creates a reliable foot contact signal
- Easy to replace sensors
Product Overview
The wireless DTS Footswitch sensor consists of 4 FSR (force sensitive resistor) switch sensors or insoles. They can be mounted on the heel and the toe or metatarsal region. It is designed for quick and easy use in clinical gait analysis. Each lead has a built-in sensitivity switch which allows for the adjustment of the switch threshold for in-shoe measurements. The FSR sensor consists of a thin circular film pad that is easy to attach.
Bilateral Ground Contact
During walking, each side creates a ground contact on/off signal. Within this scheme, any ground contact increases the signal to high level and swing phase drops the signal back to zero. This established switch scheme can be used to trigger unilateral and bilateral gait phases.
The sensor has a predefined measurement configuration in all the Noraxon software packages and is operational in a few seconds:

Application Examples
The wireless DTS Footswitch has universal functionality covering easy and quick to use setups for clinical gait screening, running and jump testing. If damage occurs due to heavy impact or shear forces (running/jumping), broken sensors are easily replaced. The special connector allows easy replacement, but keeps the sensor from falling out during testing.
4 possible attachment sites on the bottom of the foot The most established setup is: heel, metatarsal 1 and 5, toe. Double-sided tape on the back of the sensor assists in positioning it correctly. Additional taping may be required to guarantee a stable position.
B&L Foot Switch Sole Noraxon's DTS Footswitch is compatible with the well-established foot switch soles manufactured by B&L Engineering CA - U.S.A. This sole has a separation of fore and back foot region. The benefit is the speed of setup and ease of use - a perfect tool for clinicians. The sole can be ordered from Noraxon as an accessory or in place.
