  • What is Biofeedback? What are different types of biofeedback?
    Autonomic nervous system (ANS) regulates several involuntary functions of the body like heart rate, breathing rate, body temperature, blood pressure, muscle tension, and digestion. The control parameters of these bodily functions are known to be influenced by long-term exposure to stress, anxiety, depression, and other mental illnesses, which may ultimately lead to autonomic nervous system dysfunctions. Biofeedback technique has emerged as an innovative therapeutic procedure to gain a fair degree of control over some of these involuntary functions with the help of specially designed psychophysiological tasks. Basically, biofeedback is imparted as a training mechanism for mind-body control through physiological recording of bio-signals, computation of necessary parametric indices and presenting them as cues to subjects themselves with a view to achieve beneficial effects as well as suitable regulation on some of the involuntary bodily processes. The envisaged performance outcome of biofeedback training is evaluated in terms of either an augmentation or control of an underlying physiological process before and after the biofeedback training. Depending upon the type of recorded bio-signal and physiological parameters which are required to be controlled, biofeedback technique is classified into different types and few of them are mentioned below: - Heart Rate Variability Biofeedback - Neurofeedback - Breathing Biofeedback
  • What is Heart rate variability biofeedback?
    Heart rate variability biofeedback (HRVBF) involves measurement of instantaneous variations of the heart rate of subjects and presenting the metrics derived from heart rate patterns as visual or auditory cues for encouraging the subject to voluntarily control breathing at a targeted rate with a view to achieve physiologically beneficial effects. The main objective of this task is to achieve a synchrony between heart rate, arterial blood pressure and respiration. Achievement of cardio-pulmonary synchrony has been linked with improved parasympathetic autonomic control and baroreflex gain. The following are few practical examples detailing beneficial effects of practicing HRVBF: Work-Life Balance: Imagine navigating a busy workday where SNS activation is prominent. HRV biofeedback techniques can be employed during breaks to transition to a more relaxed state, enhancing overall well-being. Mindfulness Practices: Incorporating HRV biofeedback into mindfulness and relaxation exercises allows individuals to consciously influence their ANS, promoting a shift from stress to calmness. The following are the scientifically proven benefits of practicing HRVBF training: Neuroplasticity: HRV biofeedback leverages the brain's neuroplasticity, enabling individuals to train their ANS for improved adaptability. Regular practice enhances the brain's ability to adjust autonomic responses dynamically. Health Impact: Scientific studies suggest that optimizing HRV is associated with improved cardiovascular health, emotional regulation, and overall resilience to stress.
  • What is Neuro biofeedback?
    Neurofeedback (NFB) involves measuring spontaneous rhythms of the brain namely alpha, beta and theta rhythms by electroencephalography (EEG) and the feedback task is intended towards augmenting amplitude, power, or coherence of these rhythms to eventually improve mindfulness and sustained internal attention. NFB have been reported to be helpful in improving relaxation, memory recall, focus, stress management and many more
  • What is Breathing Biofeedback?
    Breathing biofeedback measures the breathing patterns from the respective sensors to practice slow breathing at a low pace using suitably designed reference respiration cues. Breathing biofeedback is widely used to treat asthma, high blood pressure, hyperventilation etc.
  • How does autonomic nervous system influence our daily life?
    Autonomic nervous system (ANS): ANS serves as the body's autopilot, finely tuning various involuntary functions. Its two main branches, the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS), work in tandem to promptly address responses to internal and external stimuli. The hypothalamus, a crucial brain region, acts as the control center, receiving continuous feedback from these nerve fibers and issuing commands to ensure the body's equilibrium (homeostasis). Sympathetic Nervous System (SNS): The SNS is the body's "fight or flight" responder, rapidly preparing it to face challenges. When activated, it reallocates resources, increasing heart rate, respiration, and blood pressure. This heightened state of alertness is essential for responding to threats or demands promptly. Parasympathetic Nervous System (PNS): In contrast, the PNS is the calming influence, promoting a "rest and digest" state. It facilitates relaxation by decreasing heart rate, respiration, and blood pressure. The PNS supports recovery, allowing the body to conserve energy and restore balance after stress or exertion. The challenge lies in maintaining a dynamic equilibrium between these two systems. A healthy autonomic balance enables individuals to effectively respond to challenges while promoting recovery during periods of rest. The importance of dynamic autonomic balance is listed below: Adaptability: An adaptable ANS ensures quick transitions between SNS and PNS dominance based on the nature of the challenge. For instance, a rapid switch from SNS activation during a high-pressure work task to PNS dominance during a lunch break ensures resilience and well-being. Chronic Stress: Prolonged SNS dominance or a sluggish transition to PNS activation can lead to chronic stress, impacting physical and mental health. HRV biofeedback aims to address these imbalances by improving the flexibility of the autonomic response. For more information, refer this article.
  • What is PPG?
    Photoplethysmography (PPG) is a simple optical technique employed for monitoring volumetric variations in peripheral blood circulation. PPG utilizes low-intensity infrared (IR) light, which, when transmitted through biological tissues, gets absorbed by bones, skin pigments, as well as venous and arterial blood. Due to the higher absorption of light by blood compared to surrounding tissues, PPG sensors can perceive changes in blood flow by detecting alterations in light intensity. The voltage signal derived from PPG is directly proportional to the volume of blood traversing the blood vessels. This method is sensitive enough to detect even minor fluctuations in blood volume, although it is not capable of quantifying the absolute blood volume. The PPG waveform consists of various components that correspond to different phases of the cardiac cycle. Systolic Peak: It represents the maximum pressure exerted by the contracting heart muscle during systole (the phase when the heart pumps blood into the arteries). Diastolic Trough: The diastolic peak corresponds to the lowest pressure in the arteries during diastole (the phase when the heart is at rest and refilling with blood). Dicrotic Notch: The dicrotic notch is a small, secondary peak or notch that appears on the descending limb of the systolic upstroke. For more information, refer this article here.
  • How Orbit app process the PPG data?
    The Orbit app captures photoplethysmogram (PPG) data synchronously at a rate of 64 samples per second. For computation of essential metrics such as Resonance score, Average HR, HRV power, and breath rate estimation, the Orbit algorithms utilize one minute of PPG data. These metrics are computed every 5 seconds by overlapping the newly recorded 5-second data with the previous 55 seconds of data.
  • What is heart rate and how it is computed from PPG signal?
    Photoplethysmogram (PPG) pulse has certain key fiducial points among which the systolic and diastolic peaks correspond to specific events in the cardiac cycle. The systolic peak represents the maximum pressure exerted by the contracting heart muscle during systole (the phase when the heart pumps blood into the arteries). The diastolic peak corresponds to the lowest pressure in the arteries during diastole (the phase when the heart is at rest and refilling with blood). Heart Rate Computation: The instantaneous heart rate is computed based on the time interval between successive systolic peaks or successive diastolic peaks in the PPG waveform and it is measured in beats per minute (BPM). The formula for calculating heart rate is:
  • What is heart rate variability?
    Heart rate variability (HRV) is a measure of variations of heart rate (HR) over time and it is regulated by two branches of Autonomic Nervous System (ANS) namely sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). These nerve fibers constantly send data to Hypothalamus of the brain to automatically regulate several involuntary functions like breathing, HR, blood pressure, digestion and many more. In Orbit app, instantaneous heart rates (IHRs) are interpolated and displayed it as Heart Rate over time graph.
  • What is heart rate variability power?
    Heart Rate Variability (HRV) power denotes the dispersion of spectral power within the heart rate variability spectrum. It provides a quantitative assessment of the autonomic nervous system's impact on fluctuations in heart rate. To calculate HRV power, the time-domain HRV signal undergoes a transformation into the frequency domain, followed by the computation of spectral power within the frequency range of 0.04 to 0.4 Hz. This analytical approach facilitates a detailed examination of how the autonomic nervous system influences the rhythmic variations in heart rate. Here are some key aspects of the significance of HRV power: Autonomic Nervous System Balance: HRV power reflects the balance between the sympathetic and parasympathetic branches of the autonomic nervous system. Monitoring changes in HRV power can provide information about the overall autonomic balance. Stress and Relaxation: Fluctuations in HRV power can indicate the body's response to stress or relaxation. Decreases in HRV, may be associated with stress and sympathetic dominance, while increased HRV may suggest a more relaxed and parasympathetic-dominant state. Cardiovascular Health: Reduced HRV power, is associated with an increased risk of cardiovascular events. It serves as a marker of cardiovascular health and is linked to the heart's ability to adapt to changing psycho-physiological demands. Training and Recovery: Athletes and fitness enthusiasts often use HRV power to monitor training loads and recovery. Changes in HRV may indicate the readiness of an individual for intense training or the need for additional recovery. Psychophysiological States: HRV power can reflect psychophysiological states, including emotional responses. For example, increased sympathetic activity may be associated with anxiety or arousal, while increased parasympathetic activity may be linked to relaxation and calmness. Sleep Quality: Increased resonance power may contribute to a more balanced autonomic state during sleep, promoting restful and restorative sleep. For more information, refer the article here.
  • What is Resonance score?
    In the realm of heart rate variability biofeedback, a phenomenon known as bio-resonance occurs when the breathing rate synchronizes with the heart rate. When the frequencies of breath rate and heart rate align, resonance prompts the heart rate to fluctuate with an increased amplitude. Naturally, the heart rate rises during inhalation and drops during exhalation. This synchronization between heart rate variability (HRV) and breath rate variability (BRV) is termed respiratory sinus arrhythmia (RSA), reflecting the body's inherent tendency. Remarkably, the most pronounced variations in heart rate (up to 12 beats per minute (BPM)) occur when slowing down the breathing to 6 cycles per minute (CPM). The resonance score is determined by assessing deviations in the amplitude of HRV from its mean. In the Orbit app, the amplitude range of 0 to 12 BPM is translated into a Resonance score ranging from 0 to 100. Results page will show the graph of the resonance score over the course of the session, displaying the time spent in low, medium, or high resonance. Physiologically, HRV power and Resonance score is interdependent and directly proportional. Therefore, physiological benefits that could be gained through increased Resonance score is similar to increased HRV power. For more information, refer the article here.
  • What is BRV and how it is measured using PPG?
    In a resting state, a healthy adult typically takes around 12 to 20 cycles per minute (CPM). It's important to note that respiratory rate can change in response to various factors, including physical activity, stress, illness, or environmental conditions. For infants, the normal respiratory rate is higher, ranging from 30 to 60 CPM. As children grow older, their respiratory rate gradually decreases and approaches the adult range. Respiratory signals are not directly captured in Photoplethysmography (PPG) signals, but they can be indirectly inferred or modulate certain characteristics of the PPG waveform. PPG is primarily used to monitor blood volume changes in peripheral blood vessels and derive information about heart rate and oxygen saturation. However, respiratory signals can influence the PPG waveform through the following mechanisms: Thoracic Pressure Changes: Respiratory movements induce changes in thoracic pressure, influencing blood flow in the thoracic vessels. These pressure changes can result in alterations in blood volume in the peripheral vessels, which may be reflected in the PPG waveform. Respiratory Sinus Arrhythmia (RSA): RSA is a phenomenon where heart rate varies in synchrony with the respiratory cycle. It is primarily controlled by the parasympathetic nervous system. While RSA is more directly observed in the electrocardiogram (ECG) signal, it can indirectly affect the PPG waveform by influencing heart rate. Orbit band uses advanced signal processing methods to extract respiratory information indirectly from PPG data. For more information, refer the article here.
