The InBodyS10: What It Is and Why You Need It

Published on June 22, 2015 by Ryan Walters

The InBodyS10 has finally arrived.  It represents portable and advanced body composition/body water analysis with the ability to test in three different positions: supine, sitting, and standing. 

The InBodyS10 features the same advanced BIA technology seen in the InBody770, but by using cabled electrodes, the InBodyS10 is able to offer analysis to individuals who need to be tested in a particular position – with special attention given to those who need to test in the supine position.  Its small size and cart allow it to be easily transported from room to room or place to place, making it a vital resource for professionals who must test many patients in various locations.

The InBodyS10, like the InBody770, offers the most accurate and extensive BIA body composition information.  It uses 6 different frequencies to analyze body water and body composition by providing 30 different impedance values to ensure accuracy.  Its portable nature and ability to test individuals who must remain in bed allow the InBodyS10 to conveniently provide essential health data to a wide range of patients.

Here are its key features:

1. Segmental ECW/TBW Analysis

      The InBodyS10 is able to determine the values of Extracellular Water and Total Body Water inside the body to give an overall ratio for ECW/TBW.  But more importantly, the InBodyS10 is able to take this analysis one step further and provide this information segmentally: in each of the arms and legs, plus the trunk.

      While the overall ratio provides a general insight into the current fluid ratio of the individual, Segmental ECW/TBW is the magnifying lens, allowing for close monitoring of water distribution in each section of the body.

      Patients who need to have their body water measured regularly - or patients who need to have excess body water removed - can benefit greatly from this analysis.  Medical procedures that reduce body water often attempt to reduce the volume of Extracellular Water a patient has to a more appropriate level for their body. 

      Every patient retains water in different places and responds to treatments differently.  The InBodyS10 helps discover what makes each patient unique so that treatments can be tailored specifically for that patient, helping them to feel more comfortable and better cared for.

      With segmental analysis, it is possible to visually observe the drop in ECW/TBW ratios across the body’s five segments after body water reduction (or accumulation) has taken place.  The segmental analysis graph can report if reduction has occurred, if it occurred symmetrically across all five areas of the body, or if there is a specific area that isn’t responding well to the treatment - which may indicate influences from other factors or conditions a person may have.

      Segmental analysis can also locate certain issues with circulation.  If, for example, the analysis reports a high ECW/TBW ratio in one of the five segments, this can indicate body water buildup in that region, which may be a sign of a potential blood clot.  Physicians can then investigate further into the cause of the buildup to treat any issues that are uncovered.

      Finally, water retention can be an indicator of nutritional health.  It is known that diet plays a significant role in the ECW/TBW ratios.  Any change in diet could cause a “spike” or large increase in the ECW/TBW ratios.  This information can help caregivers develop long-term health plans for their patients and help individuals manage their conditions more effectively through proper dietary choices. 

      2. Two Electrode Options: Touch Type and Adhesive Type

          The InBodyS10 offers two different sets of electrodes: proprietary InBody Touch Type electrodes and traditional adhesive electrodes.  These electrodes are what allow the InBodyS10 to test an individual in a standing, seated, or supine position.  Having the option to use two different sets of electrodes allows the InBodyS10 to be extremely versatile without sacrificing accuracy or efficiency.  Here are some of the advantages for each set:

          • Touch Type Electrodes

          Separated Thumb Electrodes for Reproducibility and Accuracy

            The Touch Type electrodes include hand and foot electrodes.  The hand electrodes feature specially designed thumb electrodes that clip to the thumbs of the person being tested.  These thumb electrodes incorporate patented InBody technology, which ensures that the impedance measurements begin in the same place, every time.  This technology ensures high degrees of accuracy and reproducibility, which is essential when determining hard-to-ascertain metrics such as dry weight.

            Ease of Use and Convenience

              Unlike traditional adhesive electrodes, which require training to apply to a person’s body, the Touch Type electrodes are self-contained units that clip onto the hands and attach to the ankles above the feet.  These do not require any training to apply and are easy to use, even for a non-specialist.

              The design of the Touch Type hand clips and the standard shape of the foot electrodes also ensure that regardless of who assists the patient in having an InBody Test performed, the electrodes will be placed in the same position each time.  This helps reduce the variability that can occur when attaching adhesive electrodes; different caregivers may have varying degrees of expertise in attaching adhesive electrodes.  The InBodyS10 significantly reduces variability across tests by providing these Touch Type electrodes.

              • Adhesive Type

              Special Case Testing

                Although the Touch Type electrodes have certain advantages, the InBodyS10 makes use of traditional adhesive electrodes to provide analysis for patients who are paralyzed and patients who have amputated limbs.  These individuals may have difficulty testing on traditional InBody devices, which require standing upright for a short period of time.  Although the results for the paralyzed limb(s) won't be comparable to the healthy limbs, the results for the remaining and healthy limbs will be accurate - including the ECW/TBW ratios. 

                3. Nutritional Assessment via Body Composition Analysis

                    Because the InBodyS10 is able to measure body water and perform a full body composition assessment, a patient's nutritional status can be assessed and monitored.  Although there are many factors that influence a person’s nutritional condition, the overall state can nonetheless be better understood by examining body composition data.

                    For patients who are confined to a bed, a wheelchair, or have difficulty using other methods of body composition (such as hydrostatic weighing), the InBodyS10 allows caregivers to learn the information they need regarding a patient's nutritional state with virtually zero inconvenience to the patient.

                    • Lean Body Mass

                    Poor nutritional health is associated with high amounts of fat mass and low amounts of Lean Body Mass.  Certain populations, such as the elderly – who may have difficulty having their body composition tested – are at higher risk for losing Lean Body Mass. These populations can benefit immensely from body composition analysis, especially analysis that is convenient and non-invasive.  

                    The InBodyS10 provides this by allowing these at-risk populations the ability to test in whichever position is most comfortable.  In the case of the elderly, the loss of Lean Body Mass is particularly important to monitor as the reduction of Lean Body Mass can also lead to the loss of bone density - a major health concern for these individuals and vital to monitor.  

                    Additionally, the InBodyS10 is able to determine the amounts of Body Fat Mass and Lean Body Mass and track the values over time.  Any sharp rise or decrease in either value can be detected and added to the body of data regarding a patient’s overall health.

                    • Phase Angle

                    Another useful metric the InBodyS10 provides is Whole Body Phase Angle using a 50 kHz current. Phase Angle values are also given segmentally.  Using these values, the InBodyS10 can assess how strong the cellular membranes are in a person’s body.

                    Proper nutrition includes antioxidants that can protect and reverse damage done to cell membranes.   Poor diet and nutrition, by contrast, damage cells by allowing free radicals and other harmful substances to enter the cell and cause damage.  Negative changes in Phase Angle can reflect this damage as well as reflect the effect poor nutrition has on an individual’s body.  

                    Weak cellular membranes have ramifications for long-term health; it is important to be aware of Phase Angle values as they relate to nutritional condition and work to improve them over time by ensuring appropriate essential vitamin and mineral intake.

                    Phase angles may improve (rise) with better nutritional state and fitness level, so Phase Angle can be another useful metric to develop and assess the effectiveness of dietary and fitness plans.

                    These are just a few of the main applications and features of the InBodyS10.  To learn more about the specifications and outputs, visit the InBodyS10 product page.
