Symbolic Analysis of Heart Rate Variability During Exposure to Musical Auditory Stimulation.
Alternative Therapies in Health and Medicine, 2016Co-Authors: Franciele Marques Vanderlei, Luiz Carlos De Abreu, David M. Garner, Vitor Engracia ValentiAbstract:BACKGROUND: In recent years, the application of nonlinear methods for analysis of heart rate variability (HRV) has increased. However, studies on the influence of music on cardiac autonomic modulation in those circumstances are rare. OBJECTIVE: The research team aimed to evaluate the acute effects on HRV of selected Auditory Stimulation by 2 musical styles, measuring the results using nonlinear methods of analysis: Shannon entropy, symbolic analysis, and correlation-dimension analysis. DESIGN: Prospective control study in which the volunteers were exposed to music and variables were compared between control (no Auditory Stimulation) and during exposure to music. SETTING: All procedures were performed in a sound-proofed room at the Faculty of Science and Technology at Sao Paulo State University (UNESP), Sao Paulo, Brazil. PARTICIPANTS: Participants were 22 healthy female students, aged between 18 and 30 y. INTERVENTION: Prior to the actual intervention, the participants remained at rest for 20 min, and then they were exposed to one of the selected types of music, either classical baroque (64-84 dB) or heavy-metal (75-84 dB). Each musical session lasted a total of 5 min and 15 s. At a point occurring up to 1 wk after that day, the participants listened to the second type of music. The 2 types of music were delivered in a random sequence that depended on the group to which the participant was assigned. OUTCOME MEASURES: The study analyzed the following HRV indices through Shannon entropy; symbolic analysis-0V%, 1V%, 2LV%, and 2ULV%; and correlation-dimension analysis. RESULTS: During exposure to Auditory Stimulation by heavy-metal or classical baroque music, the study established no statistically significant variations regarding the indices for the Shannon entropy; the symbolic analysis-0V%, 1V%, and 2ULV%; and the correlation-dimension analysis. However, during heavy-metal music, the 2LV% index in the symbolic analysis was reduced compared with the controls. CONCLUSIONS: Auditory Stimulation with the heavy-metal music reduced the parasympathetic modulation of HRV, whereas no significant changes occurred in cardiac autonomic modulation during exposure to the classical music.

effects of Auditory Stimulation with music of different intensities on heart period
Journal of Traditional and Complementary Medicine, 2016Co-Authors: Joice Anaize Tonon Do Amaral, Heraldo Lorena Guida, Luiz Carlos De Abreu, Viviani Barnabe, Franciele Marques Vanderlei, Vitor Engracia ValentiAbstract:Various studies have indicated that music therapy with relaxant music improves cardiac function of patients treated with cardiotoxic medication and heavy-metal music acutely reduces heart rate variability (HRV). There is also evidence that white noise Auditory Stimulation above 50 dB causes cardiac autonomic responses. In this study, we aimed to evaluate the acute effects of musical Auditory Stimulation with different intensities on cardiac autonomic regulation. This study was performed on 24 healthy women between 18 and 25 years of age. We analyzed HRV in the time [standard deviation of normal-to-normal RR intervals (SDNN), percentage of adjacent RR intervals with a difference of duration >50 ms (pNN50), and root-mean square of differences between adjacent normal RR intervals in a time interval (RMSSD)] and frequency [low frequency (LF), high frequency (HF), and LF/HF ratio] domains. HRV was recorded at rest for 10 minutes. Subsequently, the volunteers were exposed to baroque or heavy-metal music for 5 minutes through an earphone. The volunteers were exposed to three equivalent sound levels (60–70, 70–80, and 80–90 dB). After the first baroque or heavy-metal music, they remained at rest for 5 minutes and then they were exposed to the other music. The sequence of songs was randomized for each individual. Heavy-metal musical Auditory Stimulation at 80–90 dB reduced the SDNN index compared with control (44.39 ± 14.40 ms vs. 34.88 ± 8.69 ms), and Stimulation at 60–70 dB decreased the LF (ms2) index compared with control (668.83 ± 648.74 ms2 vs. 392.5 ± 179.94 ms2). Baroque music at 60–70 dB reduced the LF (ms2) index (587.75 ± 318.44 ms2 vs. 376.21 ± 178.85 ms2). In conclusion, heavy-metal and baroque musical Auditory Stimulation at lower intensities acutely reduced global modulation of the heart and only heavy-metal music reduced HRV at higher intensities.

The Effects of Musical Auditory Stimulation of Different Intensities on Geometric Indices of Heart Rate Variability.
Alternative Therapies in Health and Medicine, 2015Co-Authors: Joice Anaize Tonon Do Amaral, Heraldo Lorena Guida, Luiz Carlos De Abreu, Franciele Marques Vanderlei, David M. Garner, Elaine Osorio, Vitor Engracia ValentiAbstract:BACKGROUND: Music has been proven to promote changes in cardiac autonomic modulation. However, it is not clear whether the effects of the Auditory Stimulation on heart rate variability (HRV) are dependent on its intensity. OBJECTIVE: The study intended to investigate the acute effects on the geometric HRV indices of Auditory Stimulation with heavy metal and baroque music using different intensities of Auditory Stimulation. DESIGN: The study was a nonrandomized, clinical trial. SETTING: The study was conducted at the facility of the Faculty of Sciences of the Sao Paulo State University, on the campus in Marilia, Brazil. PARTICIPANTS: Participants were 24 healthy women aged between 18 and 27 y. INTERVENTION: HRV was recorded for each participant for 10 min at rest. Subsequently, participants were exposed to baroque or heavy metal music through an earphone. They were exposed to 3 equivalent sound levels-60-70 decibels (dB), 70-80 dB, and 80-90 dB-for 5 min in each intensity range. After the first session of baroque or heavy metal music, participants rested for an additional 5 min. Then they were exposed to the other musical style. The first style played for each musical period was randomly selected for all individuals and then the other style would be played automatically for the second session. OUTCOME MEASURES: The HRV analysis was performed using the following geometrical methods: (1) the triangular index (RRtri), (2) the triangular interpolation of the RR interval histogram (TINN), and (3) the Poincare plot, using SD1-the standard deviation of the instantaneous variability of the beat-to beat heart rate (HR), SD2-the standard deviation of the long-term, continuous, RR interval variability, and the SD1/SD2 ratio-the ratio between the short- and long-term variations among the RR intervals. RESULTS: The classic baroque music by Johann Pachelbel, "Canon in D Major," did not induce significant changes in the geometric indices of HRV at 60-70 dB, 70-80 dB, or 80-90 dB. However, Auditory Stimulation with heavy metal music, using "Heavy Metal Universe" by Gamma Ray, decreased the RRtri, TINN, and SD2 at 2 specific sound pressures (60-70 dB and 80-90 dB). CONCLUSIONS: Auditory Stimulation with the selected baroque music did not alter cardiac autonomic modulation, but the selected, heavy metal style of music in the lower and higher intensities reduced the global component of HRV acutely.

Auditory Stimulation with music influences the geometric indices of heart rate variability in response to the postural change maneuver.
Noise & Health, 2020Co-Authors: Bianca C. R. De Castro, Heraldo Lorena Guida, Luiz Carlos De Abreu, Celso Ferreira, Carlos Bandeira De Mello Monteiro, Adriano L. Roque, Renata S Marcomini, Fernando Adami, Viviane F. Ribeiro, Fernando Luiz Affonso FonsecaAbstract:It is poor in the literature the behavior of the geometric indices of heart rate variability (HRV) during the musical Auditory Stimulation. The objective is to investigate the acute effects of classic musical Auditory Stimulation on the geometric indexes of HRV in women in response to the postural change maneuver (PCM). We evaluated 11 healthy women between 18 and 25 years old. We analyzed the following indices: Triangular index, Triangular interpolation of RR intervals and Poincarι plot (standard deviation of the instantaneous variability of the beat-to beat heart rate [SD1], standard deviation of long-term continuous RR interval variability and Ratio between the short - and long-term variations of RR intervals [SD1/SD2] ratio). HRV was recorded at seated rest for 10 min. The women quickly stood up from a seated position in up to 3 s and remained standing still for 15 min. HRV was recorded at the following periods: Rest, 0-5 min, 5-10 min and 10-15 min during standing. In the second protocol, the subject was exposed to Auditory musical Stimulation (Pachelbel-Canon in D) for 10 min at seated position before standing position. Shapiro-Wilk to verify normality of data and ANOVA for repeated measures followed by the Bonferroni test for parametric variables and Friedman's followed by the Dunn's posttest for non-parametric distributions. In the first protocol, all indices were reduced at 10-15 min after the volunteers stood up. In the protocol musical Auditory Stimulation, the SD1 index was reduced at 5-10 min after the volunteers stood up compared with the music period. The SD1/SD2 ratio was decreased at control and music period compared with 5-10 min after the volunteers stood up. Musical Auditory Stimulation attenuates the cardiac autonomic responses to the PCM.

international cardiovascular research journal, 2014Co-Authors: Sheila Ap F. Da Silva, Heraldo Lorena Guida, Luiz Carlos De Abreu, Celso Ferreira, Ana Marcia Antonio, Carlos Bandeira De Mello Monteiro, Vivian F Ribeiro, Viviani Barnabe, Sidney B Silva, Fernando Luiz Affonso FonsecaAbstract:Background: No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. Objectives: The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical Auditory Stimulation on Heart Rate Variability (HRV) in healthy men. Patients and Methods: In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. Results: While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms 2 and nu) was reduced during exposure to both heavy metal and classical baroque musical Auditory Stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms 2 ) was reduced only during Auditory Stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during Auditory Stimulation with classical baroque music (P = 0.019). Conclusions: Acute Auditory Stimulation with the selected heavy metal musical Auditory Stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart.

cardiac autonomic responses induced by mental tasks and the influence of musical Auditory Stimulation
Complementary Therapies in Clinical Practice, 2014Co-Authors: Juliana Cristina Barbosa, Luiz Carlos M. Vanderlei, Heraldo Lorena Guida, Luiz Carlos De Abreu, Ana Marcia Antonio, Viviani Barnabe, Anne M G G Fontes, Renata S Marcomini, Meire Luci Da Silva, Vitor Engracia ValentiAbstract:Abstract We investigated the acute effects of musical Auditory Stimulation on cardiac autonomic responses to a mental task in 28 healthy men (18–22 years old). In the control protocol (no music), the volunteers remained at seated rest for 10 min and the test was applied for five minutes. After the end of test the subjects remained seated for five more minutes. In the music protocol, the volunteers remained at seated rest for 10 min, then were exposed to music for 10 min; the test was then applied over five minutes, and the subjects remained seated for five more minutes after the test. In the control and music protocols the time domain and frequency domain indices of heart rate variability remained unchanged before, during and after the test. We found that musical Auditory Stimulation with baroque music did not influence cardiac autonomic responses to the mental task.

Complementary Therapies in Clinical Practice, 2014Co-Authors: Juliana Cristina Barbosa, Luiz Carlos M. Vanderlei, Heraldo Lorena Guida, Luiz Carlos De Abreu, Ana Marcia Antonio, Viviani Barnabe, Anne M G G Fontes, Renata S Marcomini, Meire Luci Da Silva, Vitor Engracia ValentiAbstract:Abstract We investigated the acute effects of musical Auditory Stimulation on cardiac autonomic responses to a mental task in 28 healthy men (18–22 years old). In the control protocol (no music), the volunteers remained at seated rest for 10 min and the test was applied for five minutes. After the end of test the subjects remained seated for five more minutes. In the music protocol, the volunteers remained at seated rest for 10 min, then were exposed to music for 10 min; the test was then applied over five minutes, and the subjects remained seated for five more minutes after the test. In the control and music protocols the time domain and frequency domain indices of heart rate variability remained unchanged before, during and after the test. We found that musical Auditory Stimulation with baroque music did not influence cardiac autonomic responses to the mental task.

Auditory Stimulation with music influences the geometric indices of heart rate variability in men.
International Archives of Medicine, 2014Co-Authors: Sheila Ap F. Da Silva, Luiz Carlos M. Vanderlei, Fernando H. Sousa, Heraldo Lorena Guida, Luiz Carlos De Abreu, Lucas Lima Ferreira, Ana M Dos Santosantônio, Vitor Engracia ValentiAbstract:Background: Chronic classical music was reported to increase parasympathetic activitywhen evaluating heart rate variability (HRV). It is poor in the literature investigation of the acute effects of baroque and heavy metal styles of musical Auditory Stimulation on HRV. In this study we evaluated the acute effects of relaxant baroque and excitatory heavy metal music on the geometric indices of HRV in healthy men. Method: The study was performed in 12 healthy men between 18 and 30 years old. We excluded persons with previous experience with music instrument and those who had affinity with the song styles. We analyzed the following indices: RRtri, TINN and Poincare plot (SD1, SD2 and SD1/SD2 ratio). HRV was recorded at rest for ten minutes. Subsequently they were exposed to relaxant baroque or excitatory heavy metal music for five minutes through an earphone. After the first music exposure they remained at rest for more five minutes and them they were exposed again to Baroque or Heavy Metal music (65–80 dB). The sequence of songs was randomized for each individual. Results: The RRTri and SD2 indices were reduced during the heavy metal musical Auditory Stimulation (p 0.05).The qualitative Poincare plot analysis indicated that during relaxant classical baroque music there was observed a higher beat-to-beat dispersion of RR intervals compared with no music exposure and during excitatory heavy metal musical Auditory Stimulation, showing higher HRV.

Cardiac autonomic regulation during exposure to Auditory Stimulation with classical baroque or heavy metal music of different intensities.
Archives of the Turkish Society of Cardiology, 2014Co-Authors: Joice Anaize Tonon Do Amaral, Luiz Carlos M. Vanderlei, Heraldo Lorena Guida, Luiz Carlos De Abreu, Celso Ferreira, Vivian F Ribeiro, Marcela Leme Nogueira, Adriano L. Roque, Rodrigo Daminello Raimundo, Vitor Engracia ValentiAbstract:OBJECTIVES: The effects of chronic music Auditory Stimulation on the cardiovascular system have been investigated in the literature. However, data regarding the acute effects of different styles of music on cardiac autonomic regulation are lacking. The literature has indicated that Auditory Stimulation with white noise above 50 dB induces cardiac responses. We aimed to evaluate the acute effects of classical baroque and heavy metal music of different intensities on cardiac autonomic regulation. STUDY DESIGN: The study was performed in 16 healthy men aged 18-25 years. All procedures were performed in the same soundproof room. We analyzed heart rate variability (HRV) in time (standard deviation of normal-to-normal R-R intervals [SDNN], root-mean square of differences [RMSSD] and percentage of adjacent NN intervals with a difference of duration greater than 50 ms [pNN50]) and frequency (low frequency [LF], high frequency [HF] and LF/HF ratio) domains. HRV was recorded at rest for 10 minutes. Subsequently, the volunteers were exposed to one of the two musical styles (classical baroque or heavy metal music) for five minutes through an earphone, followed by a five-minute period of rest, and then they were exposed to the other style for another five minutes. The subjects were exposed to three equivalent sound levels (60-70dB, 70-80dB and 80-90dB). The sequence of songs was randomized for each individual. RESULTS: Auditory Stimulation with heavy metal music did not influence HRV indices in the time and frequency domains in the three equivalent sound level ranges. The same was observed with classical baroque musical Auditory Stimulation with the three equivalent sound level ranges. CONCLUSION: Musical Auditory Stimulation of different intensities did not influence cardiac autonomic regulation in men.

rhythmic Auditory Stimulation using a portable smart device short term effects on gait in chronic hemiplegic stroke patients
Journal of Physical Therapy Science, 2016Co-Authors: Byung-woo Ko, Won-kyung SongAbstract:[Purpose] The effects of various rhythmic Auditory Stimulation tempos on stroke gait pattern changes when training patients with a smartphone-based rhythmic Auditory Stimulation application were investigated. [Subjects and Methods] Fifteen patients with chronic stroke were included. Cadence during comfortable walking was measured (baseline). After the baseline findings were recorded, rhythmic Auditory Stimulation with five different tempos (i.e., −10%, −5%, 0%, +5%, and +10% change from baseline) was randomly applied. Finally, comfortable walking without rhythmic Auditory Stimulation was initiated to evaluate gait pattern changes. [Results] As the tempo increased, the spatiotemporal gait parameters of the stroke patients changed significantly. Gait speed, cadence, and gait cycle duration showed the greatest improvement in the +10% rhythmic Auditory Stimulation condition compared to baseline. After gait training with rhythmic Auditory Stimulation, gait speed, cadence, stride length, gait cycle duration, and step length of the affected and unaffected sides improved significantly compared to baseline. [Conclusion] Significant changes in the gait pattern of stroke patients were noted for various tempos after training with rhythmic Auditory Stimulation. These findings could be used to customize rehabilitative gait training for patients who experience stroke with hemiplegia.

Rhythmic Auditory Stimulation for robot-assisted gait rehabilitation: A preliminary study
2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015Co-Authors: Byung-woo Ko, Won-kyung Song, Joon-ho ShinAbstract:In therapeutic rehabilitation devices, different types of feedback are provided to improve the outcome of the rehabilitation process. Lower limb robotic exoskeleton devices for overground gait rehabilitation have difficulties providing subjects certain types of feedback, such as visual feedback, because of the restriction of the visual display installation space and the mobility of the whole system. As a remedy, we propose the concept of providing Auditory Stimulation with force feedback via exoskeleton legs. As a preliminary study, we implemented an Android OS-based rhythmic Auditory Stimulation module in order to effectively connect exoskeleton robotic devices. Two 3D accelerometers were attached around the subjects' ankles. By using this module, we performed a preliminary study on rhythmic Auditory Stimulation with able-bodied participants and one stroke participant. We observed changes in gait speed, cadence, and stride length in accordance with the rhythmic Auditory Stimulation. Based on these findings, a smartphone-based rhythmic Auditory stimulator could add value to exoskeleton robotic devices.
