“…SD1 (standard deviation of points perpendicular to the line-of-equality) measured the short-term HRV and is associated with the influence of parasympathetic activity. Moreover, it is similar to RMSSD (root mean square of successive IBI differences) and associated positively to HF power (power of highfrequency band: 0.15 -0.4 Hz)[29,64,65].…”

BACKGROUND: It is well known that health status of paramedics may be altered by their job demands. However, it is unknown whether health conditions have a negative impact on occupational performance. The goal of this study was to explore whether a paramedic’s health status affects performance during a patient-care simulation. More precisely, this paper aims to identify which health conditions (i.e., cardiovascular diseases (CVD), musculoskeletal disorders (MSD), post-traumatic stress disorders (PTSD), generalized anxiety disorders (GAD)) could be associated with negative performance. METHODS: Nineteen paramedics aged 38.2 ± 8.6 years old with 15.0 ± 8.7 years of paramedic experience participated in this study. Participants completed two assessments: i) health conditions measurements and ii) patient-care simulation. Heart rate variability (HRV), an indicator of vagal activity was collected during the patient-care simulation. The simulation was used in order to challenge experienced paramedics in a realistic setting. Based on the provincial standard of New Brunswick, an experienced paramedic instructor graded (passed or failed) the patient-care simulation using the provincial standard charts, videos and data from manikin. RESULTS: The current study suggests that only paramedics with self-reported elevated symptoms of PTSD were less likely to successfully complete the simulated patient-care scenario. An inhibition of the vagal activity was noted during the patient-care simulation among individuals identified with PTSD. No link was observed between physical health conditions (CVD, MSD) and simulated patient-care performance. Overall, paramedics who passed the patient-care simulation presented higher vagal activity during the patient assessment. CONCLUSIONS: This research suggests that the presence of self-reported elevated symptoms of PTSD negatively impacts paramedics’ performance during a stressful work task simulation. Therefore, to help paramedics maintain optimal performance, it may be important to ensure that paramedics have access to appropriate resources to monitor and improve their psychosocial health. Future studies should investigate more complex work tasks with larger sample sizes and more complex simulations.

“…We will also explore other aspects of HRV according to Task Force Standards (35) to get an overall impression of the subjects' HRV. In a recent study that examined the reliability of HRV measures, the sample size was estimated to 20 subjects in each group to detect a mean change of 20% in RMSSD, and 20-50 subjects in each group to detect a change of 10% (36). A difference of 10-20% has been considered to be clinically important (36).…”

Background Recent experimental research has suggested that Spinal Manipulative Therapy (SMT) may reduce pain through modulation of the ascending pain signals and/or the central pain regulating mechanisms. People with persistent neck pain (NP) have also been found to have disturbances in Autonomic Nervous System (ANS) regulation. A common way to study ANS is to measure heart rate variability (HRV). It is not known if deviations in HRV are related to changes in pain perception or to the treatment response to SMT. Commonly, an individual in pain will experience pain reduction when exposed to a second pain stimulus, a mechanism known as Conditioning Pain Modulation (CPM). Patients with persistent pain have been found to have a reduced CPM reaction. It is not known if this is predictive of treatment response to SMT. The aim of the study is to examine the effects of SMT on HRV and pain and to test if a CPM test can be used to predict treatment response, in a population of patients with recurrent and persistent NP. Method/Design A multicentre randomized controlled clinical trial will be carried out in multidisciplinary primary care clinics. This setting is chosen to minimize bias resulting from patient preference to treatment modality and provider. The subjects are either self-referred or referred from other health care practitioners locally. The treatment modalities are two well-known interventions for NP; SMT and stretching exercises compared to stretching exercises alone. The subjective pain experience will be investigated by assessing pain intensity and the affective quality of pain. HRV will be measured using a portable heart monitor and CPM will be measured with a standardized cold-pressor-test. Measurements will be performed at baseline, prior to the third treatment and after the fourth treatment. Discussion The study will utilize normal clinical procedures, which should aid transferability and external validity of the results. The study will provide knowledge regarding the underlying mechanisms of the effects of SMT. Furthermore, the study will examine if a CPM test is predictive of treatment outcome in a population of patients with recurrent and persistent NP.

thetic and parasympathetic nervous systems by means of beat-to-beat regulation of heart rate. 12 Recently, we reported that HRV was strongly associated with IR and insulin sensitivity in a Japanese population, 13 and we speculated that this was linked to dysfunction of the hepatic insulin-sensitizing substance (HISS) pathway, which is controlled by vagal tone. 14,15 Thus, low HRV resulting from parasympathetic dysfunction is likely to precede impaired insulin function 16 and increased inflammatory activity, 17 thus raising CVD risk. Several studies have documented the association between HRV and MetS, 18 but few have considered the influence of IR and insulin sensitivity on this association in the general population. Metabolic syndrome (MetS) is a diagnosis involving clustered cardiovascular risk factors. 1 Pathologically, insulin resistance (IR) or impaired insulin sensitivity is considered to be the underlying mechanism of MetS. 2,3 Despite differing MetS definitions across ethnicities, the accumulation of multiple risk factors has been shown to significantly elevate the risk of cardiovascular disease (CVD) outcomes or sudden cardiac death. 4-7Heart rate variability (HRV) is regulated predominantly by cardiac vagal tone, and lower HRV has been associated with an increased risk of diabetes, hypertension, and CVD in epidemiologic studies. 8-11 HRV assessment is a useful noninvasive tool that reflects the activity of the sympa- Background: Insulin resistance is strongly associated with metabolic syndrome (MetS), but it is not known how this association is influenced by the autonomic nervous system, which controls insulin secretion.
