IMPORTANT: GaitSens 2.0 is intended for light commercial, rehabilitation, and home use. 2. Quick Start Congratulations on the purchase of the GaitSens 2.0 gait analysis software designed specifically for the busy rehabilitation clinic. This quick reference guide will help you get your GaitSens running quickly. a. Plug the GaitSens enabled treadmill into an appropriate electrical outlet per the specifications of the treadmill. GaitSens is powered from the treadmill so does not require any additional outlet plug. b. Wait at least 15 seconds after the treadmill has been plugged in before opening the GaitSens application in the tablet for Android. c. Click on the GaitSens icon in the provided tablet. Within Bluetooth Range (Less than 30 feet away from treadmill) Outside Bluetooth Range (Greater than 30 feet away from treadmill) Initialize Treadmill i. Ensure treadmill is level with all four adjustable feet touching ground. ii. Remove all weight from the treadmill and ensure the treadmill is not touched during initialization iii. Press Initialize. Error Prompt to: Quit close out the treadmill application Run Disconnected Run the application without connection to review previously recorded sessions. Connect Attempt to reconnect. IMPORTANT: If the treadmill has been moved since the last use of GaitSens, for best results validate that the zero values are accurate. Complete Validation Instructions found on page 7. 4

25 17. Calibration NOTE: Calibration should only be performed if values are skewed. Errors in calibration procedure will effect captured data. For assistance during calibration process, please contact the Service & Parts department at EXT Click to calibrate GaitSens. 2. Enter your weight. 3. The calibration will first ask for you to stand off of the treadmill. Additional weight to the treadmill will skew the calibration of the instrumentation. 4. Follow the calibration steps as shown below. 5. The final step asks for you to stand off of the treadmill. Additional weight to the treadmill will skew the calibration of the instrumentation. 6. Press Finish to complete calibration. NOTE: Upon completion of calibration a dialogue box will display the Total Calibration correction coefficient. This value is for Mobility Research Use only.

28 19 - Reference - Normal Values Normal Values: Session results were gathered using a set of 30 "typical" adults who walked on a GaitSens enabled treadmill, at 5 different walking speeds (0.5mph, 1 mph,1.5 mph,2.0 mph, 2.5 mph). The software compares your user s data with the mean of the data collected from this normal population, based upon the average speed of the session.
