Objective:To investigate the effects of an exercise-training program on heart-rate-variability (HRV) indices in individuals with Down syndrome (DS).Design:Controlled clinical trial.Participants:10 people with DS, age 24.2 ± 5.1 y (group A), and 10 age-matched healthy sedentary individuals (group B).Method:At baseline all subjects underwent a clinical examination and an ambulatory 24-h Holter monitoring for the evaluation of cardiac autonomic-nervous-system (ANS) activity by time- and frequency-domain analysis.Intervention:After initial evaluation, group A followed a 6-mo exercise-training program and thereafter underwent the same HRV analysis.Results:At the beginning of the study, group A showed a higher LF:HF ratio than group B, indicating impaired sympathovagal balance, likely because of lesser vagal modulation. Moreover, both time- and frequency-domain indices in group A were significantly lower than in group B. At the end of the study, exercise training was found to improve the sympathovagal balance, mainly by increasing vagal activity, in group A.Conclusion:The results indicate that individuals with DS have ANS dysfunction that can be improved by exercise’s increasing the parasympathetic modulation.

Purpose: This study aimed to analyze the effect of a Pilates protocol on respiratory muscle strength and heart rate variability (HRV) in patients with type 2 diabetes. Method: A randomized clinical trial (RBR-2gc2qj) was conducted with a type 2 diabetic target population. Patients practiced the Pilates protocol for 8 weeks, with two visits per week. The variables tested were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and HRV (time and frequency domains). All variables were tested for normal distribution. Using SPSS 21.0, analysis of variance was performed for variables with normal distribution, and the Wilcoxon and Friedman tests were used for variables that did not show a normal distribution, with a 5% significance level. Results: Forty-four participants were included in the study (intervention group: 22; control group: 22; mean age: 61.23 ± 8.49 years), most of whom were female (77.3%), married or in a consensual union (59.1%), had complete literacy (31.8%), and had an average body mass index of 26.96 ± 4.35 kg/m2. There were no significant differences in MIP and MEP before and after the protocol between the intervention and control groups. Regarding HRV, there were significant differences in autonomic modulation, especially between the moments before and during exercise and between the moments during and after exercise; however, it was not possible to determine which system (sympathetic or parasympathetic) is most involved in these changes. Conclusion: The exercise protocol based on the Pilates method did not alter respiratory muscle strength but promoted changes in HRV, especially between the moments before and during exercise and during and after exercise.

Capillary Blood Sampling

Aim: The aim of the study was to assess the severity of pain experienced by a newborn during a heel puncture for screening using the Newborn Pain Scale (NIPS), measure the heart rate and compare the effectiveness of non-pharmacological methods of pain control. Design: Randomized clinical trial. No experimental factors. The test was performed during routine screening. Surroundings: Provincial Specialist Hospital in Olsztyn. Patients/Participants: Pain was assessed in 90 full-term newborns. The newborns were rooming in with their mothers in the hospital. Interventions: Newborns were divided into three groups. Three different methods of pain relief were used: breastfeeding, 20% glucose administered orally and non-nutritional sucking. Main Outcome Measures: The primary pain outcome was measured using the NIPS and the secondary pain outcome measures (heart rate, oxygen saturation) were measured using a pulse oximeter. Results: During capillary blood sampling from the heel, most newborns, n = 56 (62.2%), experienced no pain or mild discomfort, severe pain occurred in n = 23 (25.6%) and moderate pain occurred in n = 11 (12.2%). No significant statistical differences were found between the degree of pain intensity and the intervention used to minimize the pain p = 0.24. Statistically significant relationships were demonstrated between heart rate variability and the degree of pain intensity (p = 0. 01). There were no statistically significant differences between the newborn’s pain intensity and the mother’s opinion on the effectiveness of breastfeeding in minimizing pain. Conclusions: This study did not answer the question of which pain management method used during the heel prick was statistically more effective in reducing pain. However, the results indicate that each of the non-pharmacological interventions (breastfeeding, oral glucose dosing and non-nutritive sucking) applied during heel puncture resulted in effective pain management in most of the newborns enrolled in the study. The relationship between heart rate variability and the severity of pain was confirmed. Mothers of newborns in the breastfeeding group were satisfied with the pain relief methods used in the child and the opportunity to console their newborn during painful procedures in a technologically invasive environment.

Measurement Period

Traditionally, resting heart rate variability (rHRV) is measured for 10 min using the last 5 min for analyses (e.g., criterion period). It is unknown whether the measurement period can be shortened in pregnant women as there are currently no established standards. We aimed to compare shorter time segments (e.g., from the 1st to 10th minutes) of the parasympathetic index natural logarithm transformation of root mean square of successive R–R differences (Ln rMSSD) with the criterion period in pregnant and nonpregnant women. Twelve pregnant (age: 30.8 ± 3.4 years; gestational age: 20.1 ± 5.0 weeks) and 15 nonpregnant women (age: 29.8 ± 4.0 years) were included. rHRV was measured using a portable heart rate monitor for 10 min while sitting. Ln rMSSD difference/agreement between shorter time segments and criterion period was analyzed. The result observed between the 4th–5th minutes was the shortest time segment not different from/highly agreed with the criterion period in pregnant women (difference [95% confidence interval (CI)]: −0.10 [−0.22 to 0.02]/bias ± 1.96 × SD: −0.06 [−0.38 to 0.25]). In nonpregnant women, the 2nd–3rd-minute segment was the shortest with similar results (difference [95% CI]: −0.04 [−0.15 to 0.07]/bias ± 1.96 × SD: −0.03 [−0.39 to 0.32]). The Ln rMSSD was found to be stable from the 5th–10th minutes and the 3rd–10th minutes in pregnant and nonpregnant women, respectively. A shortened rHRV assessment can increase its applicability in clinical/exercise-training settings. Novelty Ln rMSSD can be measured for 5 min in pregnant women, with the last 1-min segment analyzed. The last 1-min segment from 3 min can be used for rHRV measurement in nonpregnant women. The shortened rHRV assessment can facilitate its applicability in clinical/exercise-training settings.
