Ultium Footswitch SmartLead User Manual

2 Introduction

2.1 Brief Description

The foot contact sensor lead consists of 4 FSR (force sensitive resistor) switch sensors which consist
of a thin circular film pad that is easy to attach. 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. The Footswitch
SmartLead works with Noraxon Ultium EMG system as an accessory to the Ultium EMG Sensor (#810).
The Footswitch SmartLead 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.
The Footswitch SmartLead is also compatible with Noraxon Footswitch insoles. The insole has a
separation of forefoot and back foot region. The benefit is the speed of set-up and ease of use - a
perfect tool for clinicians. The sole can be ordered as an accessory or in place of the single FSR-sensor
leads.
The insoles have 4 active pressure sensing areas. The threshold pressure required to initiate an off-to-
on response of the 4 areas can be adjusted by the user. Thus, individuals of various body weight can be
accommodated by adjustment of the insole sensitivity.

2.2 Contraindications

Use of the Ultium system is contra-indicated in individuals who have implanted pacemakers.
