Assessment of the implementation & interpretation of measurements for prostheses

Patient population:
Wearers of prostheses, in particular knee and/or total hip joint endoprostheses (hereinafter knee TEP or hip TEP).

1. May a measurement be carried out at all or are there contraindications?
   Answer: Yes, a measurement may be carried out. The contraindications (see operating instructions for the above-mentioned devices) list "active prostheses" as an exclusion criterion. Active prostheses are high-tech prostheses with circuitry, electric motors etc., for example to generate force with the artificial leg when climbing stairs. Endoprostheses such as knee and hip TEPs are made of metal and/or ceramic, but do not have a circuit that can be damaged by the BIA current.
2. Can a measurement be successfully performed by the device?
   Answer: Yes, a measurement can be successfully performed by the device. The seca mBCA devices have internal quality checkers which cancel the measurement in the event of abnormal body resistance (e.g. movement during the measurement). This prevents inaccurate results. However, as the current does not usually flow through the knee or hip TEPs, the body resistances do not change.
3. Does the measurement provide accurate results?
   Answer: Yes, a measurement provides accurate results for clinical use. Since the prostheses are typically not detected by the current, but the current only flows under the skin through the muscles, the prostheses do not influence the measurement result.
4. Is there anything else that needs to be taken into account?
   Answer: Yes, fresh fractures (e.g. femoral neck head) and surgical treatment (e.g. by means of hip replacement) lead to (local) oedema formation. This must be taken into account when measuring people with fresh fractures or immediately after surgery. Accurate results can be expected after local healing.

Below is some information on contraindications: 

• Height and weight measurement is generally possible for all patients.
• Bioimpedance measurements must not be carried out on people with the following characteristics:
  Electronic implants, e.g. pacemakers- Active prostheses- Glucose measurement sensor under the skin e.g. FreeStyle Libre
• Bioimpedance measurements must not be carried out on persons connected to one of the following devices:
  Life-sustaining electronic systems, e.g. artificial heart, artificial lung- Portable electronic medical devices, e.g. ECG devices or infusion pumps
• For persons with the following characteristics, bioimpedance measurements may only be carried out after consultation with the attending physician:
  Cardiac arrhythmia- Pregnancy
• Purely metallic devices (e.g. TEPs, stents) have no influence on the measurement or the health of your patient/client.

First check the seca services and restart them if necessary (quit first, then start, do not use the restart function). Open the services by entering "Services" in the search bar of your PC (in Windows on the start screen at the bottom left) and opening the result found (the Services app). Now click on any service in the window that opens and tap "S" on the keyboard. Then scroll to find all services that start with "seca". Right-click on the services individually and select "Exit" and then "Start" in the menu that appears. When you have finished with all seca services, please search for the "postgresql" service and do the same with it.

If the error still occurs, please have the firewall port settings checked. This can be done manually by your IT department.

The following ports must be enabled:

Inbound and outbound:

Is another "third-party software" programme (e.g. McAfee, Kaspersky, etc.) running in addition to the normal Windows firewall settings? If so, you must deactivate it or set the seca services as trustworthy.

Then check whether the LAN cable connection has been installed correctly and whether the cable shows any external damage.

As a final check, please look at the IP settings on the PC and on the scale. Please check whether both devices are in the same ranch and can communicate. On the PC, you can check and change the Ethernet settings in the "Network connections" menu. On the seca scale, you must open the admin settings. Click on "Units" in the top right-hand corner to open a drop-down menu. In this drop-down menu, please select the item "Ethernet Network" or "seca CLS network". You can make the necessary improvements there.

General correct preparation and checking of the measurement

Firstly, check that the electrodes have been attached correctly and that the skin contact is good. You should then check the position of the patient/client. Is the position relaxed? Has the patient/client remained in this position for 15 minutes? Does the patient/customer have any prostheses or other metallic accessories on or in the body? Does the patient/customer have any special characteristics (e.g. nephrological)? The further procedure depends on the type of connection between the measuring mat and the monitor.

Connection of the measuring mat via infrared
If the measuring mat is connected via infrared, you will not see any measurement results until you have connected the measuring mat to the monitor. If no data is transmitted even though the mat is correctly attached, you must contact seca Service.

Connecting the measuring mat via wireless module (W-LAN)
If you have connected the measuring mat via the wireless module and the measurement is cancelled with an error message after the start process or does not start at all, you must check the connection between the measuring mat and the monitor.

There are two different ways to switch on the measuring mat:

The first option happens automatically when the measuring mat and monitor are connected. Connect the measuring mat to the monitor by magnetically attaching the measuring mat to the holder provided on the back of the monitor in the plastic tray. Then start the monitor if it has not yet been switched on. You then just have to wait and as soon as you see the green measuring mat symbol at the bottom right of the monitor (directly to the left of the monitor's battery symbol), the measuring mat is switched on. If it is not switched on after approx. 60 seconds, please check whether the measuring mat is correctly attached to the holder. Alternatively, use the second method to switch on the measuring mat.

The second option is to switch on the measuring mat manually. To do this, simply press the play button (the button with the "play symbol", circled triangle) for approx. 1 second. All LEDs will first light up green, then red and finally go out again. The green LED above the battery indicator will light up. This lets you know that the measuring mat has a battery and is charged. The green LED above the WLAN symbol will then flash and search for the monitor via radio. The mat is now switched on.

If the manual method does not work either, leave the measuring mat to charge for approx. 15 minutes with the monitor switched on to ensure that the battery has charged. 

First plug the power cable (IEC plug) into the monitor and, after a short wait, test again to see if the monitor cannot be switched on. If it can be switched on, allow the battery to charge.

If the monitor still cannot be switched on, disconnect the power plug again. If the monitor is completely discharged, you can reset the battery. To do this, press the on/off switch (status plug) for 10 seconds. If this does not help, use a different location to connect the monitor. Replace the power cable if necessary.

If you have the problem with the missing display of the ASMI, please check the following on your PC, which contains the 115 software.

To activate ASMI  
Add a configuration parameter "AlwaysEnableASMI" to the file "C:\Program Files (x86)\seca\software\Seca.Analytics.exe.config".
The default value is "false", which leads to the missing ASMI.
If this setting is changed to "true", the ASMI implementation is used regardless of the configured setup location.

In this case, the seca analytics 115 software cannot find the Mediator service, even if the server IP is entered in the GUI settings.

Solution:
Please search for the following file in the installation path of the software:
C:\Program Files (x86)\seca\software\Seca.Analytics.exe.config

Edit these lines and enter the server IP under "Server IP":
    <servicesToContactOnStartup>
      <add key="MediatorService" value="SERVER IP:20001" />
    </servicesToContactOnStartup>

Please remove the following characters in the file:
    <!-- at the beginning
and
-- > at the end of the section

Make sure that neither the arms of the person to be measured are touching the torso or the legs/thighs. If this is the case, place something between the arms and torso or between the thighs (towel). 

Check whether there are any prostheses, metal objects or similar. You should also check whether the grip and contact between the skin and electrodes is guaranteed. You can use disinfectant or contact gel if the skin is very dry. 

If the error persists, this error message must be analysed by seca. In preparation, please repeat the measurements with at least 3 different people and then save the system log file in the admin menu of the mBCA 525 on a USB stick. The default admin pin is 1357. The option for the system log export can be found under System / Data management.

 

Please only use chlorine- and alcohol-free cleaning agents that are explicitly suitable for acrylic glass and other sensitive surfaces (active ingredient: e.g. quaternary ammonium compounds).

The USB stick may only have a maximum capacity of 4 GB and should be formatted as follows:

USB version: USB 2.0 only
Format: FAT16 and FAT only (NO exFAT)
Size: Maximum 2 GB

To partition a USB stick, please proceed as follows (ADMIN RIGHTS for the computer are NECESSARY):

Open CMD (Windows key --> CMD)
Enter "Diskpart" in CMD
Enter the following commands one after the other in Diskpart:
list disk
select disk [disc number]
clean
create partition primary
active
Format the stick as FAT using the Explorer.

The stick should now be recognised. However, the USB stick is empty and must be re-recorded with the necessary files (e.g. the desired update file).

If you have measurement results that deviate from the norm, please send us the data for interpretation. Please send the important data of the person being measured (e.g. professional athletes, certain illnesses, medication, generally anything that is important and could influence the result) and the circumstances (sore muscles, changes in diet, time, etc.) to seca Service. The results will be analysed and, if necessary, discussed with you in a telephone call.

The following applies to the end customer:
If you have any further questions about your body composition, please contact the person who carried out your body composition analysis, for example your trainer, doctor or nutritionist. seca does not provide advice on body composition.

If an implausibly low value for visceral adipose tissue (VAT) is displayed, which is inconsistent with a high waist circumference, then the impedance of the trunk is probably very low. This may be due to water retention in the torso, which then leads to an overestimation of the fat-free mass and thus to an underestimation of the fat. To be on the safe side, you should also check once again whether the height, age and gender are correct.

A body composition with an implausible fat mass is occasionally displayed. This appears to be a particular problem for competitive athletes and is not limited to bioimpedance measurement. For example, we are also familiar with such results from air displacement plethysmography or underwater weighing. We are currently looking for the cause of such anomalies. In order to be able to analyse this case in more detail, we would be pleased if you could provide us with the measured values as a csv export from seca Analytics 115. This csv export should contain at least height, weight and impedance raw data so that we can understand the calculations. Are there any indications of a deviating body water percentage? An increased body water percentage could lead to an overestimation of the fat-free mass and thus to an underestimation of the fat mass; an unusually low body water percentage could lead to an overestimation of the fat mass.
