    The system is synchronized with the Vicon motion capture system, but can be synchronized with other Functional Assessment (FA) devices. This document will explain the setup of the TeleMyo DTS EMG system on its own, and the setup for the system in conjunction with the Vicon system.

    PC-POD-FA-001-v02 3. Procedure Whether the device will be used with the Noraxon data collection package or with the Vicon system, the basic principles regarding the use of the device are the same. Outlined in this section are instruction on operating the EMG probes, electrode recommendations and an overview of principles regarding EMG.
  • Page 9: Skin Preparation

    Skin preparation for the reference pad site may be beneficial if the EMG signal exhibits a wandering baseline. The EMG Transmitter can be secured in place using Noraxon supplied double sided adhesive tape and/or elastic straps. Straps are recommended if very dynamic movements are expected.

    PC-POD-FA-001-v02 2. Use small electrodes to increase the selectivity of your measures (avoid cross-talk) 3. The recommendation for the inter-electrode distance is 2 cm 4. Apply electrodes in series to the muscle fiber direction 5. Use the dominant middle portion of the muscle belly for best selectivity 6.

Checking all connections again can confirm the EMG signal by a specific muscle function test for that particular muscle (i.e. elbow flexion to test biceps brachii).

  • Page 14: Data Acquisition

    Plug in the TeleMyo DTS receiver to the Vicon computer via USB. Ensure there are no internet browsers open at the same time as there is an issue with the acquisition computer being connected to the internet while trying to collect data.

    PC-POD-FA-001-v02 N.B. If the participant is performing very dynamic movements or is sitting down between trials, ensure that the probes remain in contact with the participant. 5.2 XP Master Edition 5.2.1Main screen elements Project is the highest level in the hierarchy of the MyoResearch XP database. This level can be used to separate different projects or users working in the same version.
  • Page 16 PC-POD-FA-001-v02 The left pane is the Muscle/Device Maps where you can review the recommended EMG placement sites for muscles, select different peripheral devices, etc. In the center is the Channels pane. Here, the user can select which channel they desire to record, which side of the body they are recording (which changes depending on muscle selection), the name of the channel (which also changes depending on selection), the type of recording (default is EMG) the amplitude (default is 500), the units (default is µV) and whether or not this channel will be recorded (default is set to record).

After you have finished all the data acquisition for a selected muscle, click Database to return to the Subject Database menu. From here, you can highlight your newly acquired data and begin processing it.

    PC-POD-FA-001-v02 shape, depending on which analysis protocol you decide to use. Typically, stored EMG data is processed by several signal processing methods such as rectification, smoothing and normalization before an analysis is started (exception: frequency based analysis types). Any signal can be restored to its original raw status. Five Signal Processing methods, listed under Available Operations, can be loaded in a sequence of Selected Operations.
  • Page 19 PC-POD-FA-001-v02 Manual Value: Here the normalization value can be entered manually. You can apply manual values per channel. Peak value: This is the main method of finding MVC (Maximum Voluntary Contraction) values within MVC records. The entry Window defines a window for the MVC value calculation.
