Relationship Between Measurement Site and Motion Artifacts in Wearable Reflected Photoplethysmography

Maeda, Yuka, Sekine, Masaki, Tamura, Toshiyo·2011·Journal of Medical Systems

Abstract

Pulse rates obtained from wearable photoplethysmography (PPG) sensors are important for monitoring cardiovascular condition, especially during exercise. However, it is difficult to precisely count pulse rates during exercise because PPG is sensitive to body movement. The artifacts from body movement are caused by a change in the blood volume at the measurement site, in addition to pulsatile changes. Here, we investigated the influence of motion artifact with respect to light source and anatomical sites. In this study, we compared the signal from green-light PPG to that from infrared PPG at different anatomical sites. In these experiments, 11 subjects were asked to either assume a resting position or generate spontaneous motion artifact by jumping and swinging their arm. As a result, pulse rates obtained from green-light PPG showed a higher correlation with the ECG R-R interval as compared to those obtained with infrared. Additionally, the signal from the upper arm showed less artifact than did the peripheral one. Therefore, the green-light PPG may be useful for pulse rate monitoring.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Intensity-linked improvements are modest rather than decisive, but suggest that PPG systems may perform comparatively better when stroke volume and pulsatility increase.

    “We therefore interpret intensity-linked improvements as modest rather than decisive, but they do suggest that PPG systems may perform comparatively better when stroke volume and pulsatility increase [2,29].”
  • The Mio Alpha has displayed more accurate measurement of heart rate in conjunction with an accelerometer compared to an infrared heart rate system when compensating for movement artifacts.

    “and has displayed more accurate measurement of heart rate in conjunction with an accelerometer compared to an infrared heart rate system when compensating for movement artifacts (Maeda, Sekine, Tamura, 2011b).”

  • Motion artifacts are a primary cause of bad signal quality.

    “Motion artifacts are a primary cause of bad signal quality, and research has suggested various methods for mitigating these26,39,40.”

  • Artifact characteristics from finger oximetry and neck PPG cannot be straightforwardly transferred to simulating wrist PPG because distinct body locations have different tissue optical properties for different wavelengths and are prone to specific interference.

    “Nevertheless, these artifact characteristics cannot be straightforwardly transferred to simulating the wrist PPG since distinct body locations have different tissue optical properties for different wavelengths and are prone to specific interference [54].”
  • Alternative measurement sites such as the arm, ear, chest, or face can have advantages over the wrist, including being less prone to motion artifact or vasoconstriction and providing more accurate heart rate measurements.

    “These alternative sites can have advantages over the wrist, such as being less prone to motion artifact [63] or vasoconstriction [62], and providing more accurate HR measurements [64].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
