Abstract
Objective To analyze the consistency of study designs in osteopathic manipulative treatment (OMT) research, focusing on blinding protocols and the use of sham treatments. Data Source and Study Selection PubMed and CINAHL were searched in January 2022. A total of 83 research studies between 2009 and 2021 were selected based on the presence of a double- or single-blind study design and/or sham treatment. Data Extraction and Analysis Data regarding the primary outcome measures, blinding design, measures used to determine success of blinding, osteopathic technique used, and sham technique used for each eligible study were extracted and compared among different study designs. Results A total of 5968 subjects participated in the 83 trials. The study population mainly consisted of asymptomatic individuals (25%) and chronic back pain patients (19%). Light touch was employed most commonly (49%) as the sham treatment, followed by unrelated sham (20%) and incomplete maneuvers (20%). Most studies blinded the subjects (80%) or the outcome evaluator/data analyzer (71%), while only 20% studies blinded the osteopathic physicians. Conclusions Strict double-blinding is achievable for OMT clinical research by blinding the subjects and data collectors/analyzers rather than the osteopaths providing the actual treatment. The use of questionnaires to determine the success of blinding should be considered. Additionally, including OMT-naïve subjects is preferred to enhance blinding success. When designing a sham treatment, careful consideration should be given to blinding the data collector, accounting for the placebo effect, and incorporating an additional no-treatment control group to improve the rigor of the study design.

A Randomised Controlled Pilot Study. Healthcare (Basel) 2024; 12:138. [PMID: 38255026 PMCID: PMC10815744 DOI: 10.3390/healthcare12020138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/23/2023] [Accepted: 12/27/2023] [Indexed: 01/24/2024] Open
Abstract
Heart rate variability (HRV) describes fluctuations in time intervals between heartbeats and reflects autonomic activity. HRV is reduced in stressed patients with musculoskeletal pain and improved after osteopathic manipulative treatment and mind-body interventions. Heart-focused palpation (HFP) combines manual and mind-body approaches to facilitate relaxation. This randomised controlled pilot study investigated the feasibility and sample size for a future randomised controlled trial and the effect of a single treatment with HFP or sham HFP (SHAM) on short-term HRV. A total of Thirty-three adults (47.7 ± 13.5 years old) with stress and musculoskeletal pain completed the trial with acceptable rates of recruitment (8.25 subjects per site/month), retention (100%), adherence (100%), and adverse events (0%). HFP (n = 18), but not SHAM (n = 15), significantly increased the root mean square of successive RR interval differences (p = 0.036), standard deviation of the NN intervals (p = 0.009), and ratio of the low-frequency to high-frequency power band (p = 0.026). HFP and SHAM significantly decreased the heart rate (p < 0.001, p = 0.009) but not the stress index and ratio of the Poincaré plot standard deviation along and perpendicular to the line of identity (p > 0.05). A power analysis calculated 72 participants. Taken together, the study was feasible and HFP improved HRV in stressed subjects with musculoskeletal pain, suggesting a parasympathetic effect.

Abstract
Heart rate variability (HRV) is a simple tool to monitor cardiovascular stress. The proper function of the cardiovascular system is a problem among firefighters. Physical activity has health benefits correlated with psychological stress. Physically active people should be more resilient to psychological stress, but this has not always been demonstrated. The aim of this study was to determine whether cranial techniques would have an effect on HRV parameters. Osteopathy in the cranium reduces stress and improves cardiovascular function. Fifty-seven firefighter cadets aged 18-24 years (21.63 ± 1.41) participated in the study. All subjects had their heart rate variability measured and were randomly assigned either to the cranial techniques (CS) group, with therapy performed once a week for 5 weeks), or to the control group (CO). After 5 weeks, heart rate variability was measured again in both groups. In the Friedman test, in the CS group there was a statistically significant effect of cranial techniques on Heart Rate (HR) and Low Frequency (LF), but not on High Frequency (HF); in the CO group, a statistically significant difference was observed for HR, HF and LF. In the Nemenyi test, in the CS group there was a statistically significant difference for HR and LF and in the CO group for HR, HF and LF. After applying hierarchical clustering with Euclidean measure and the complete method, dendrograms were drawn up showing similarities for HR, HF and LF values. The cranial techniques and touch might exert a beneficial effect on HRV. Both factors can be used in stressful situations to lower HRV.

J Manipulative Physiol Ther 2022; 45:104-113. [PMID: 35753877 DOI: 10.1016/j.jmpt.2022.03.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 03/21/2022] [Accepted: 03/22/2022] [Indexed: 10/17/2022]
Abstract
OBJECTIVE The purpose of this study was to identify sources and strategies for the mitigation of bias in studies of spinal manipulation and heart rate variability. METHODS A small-scale study compared the effects of a single session of sham and authentic cervical manipulation on heart rate variability as measured by power spectrum analysis. The participants were a sample of 31 healthy young students from the Canadian Memorial Chiropractic College, randomized into 2 study arms. The effectiveness of blinding was evaluated, and 2 alternative methods of data analysis were explored to mitigate risk of bias. Following execution of the study, the stages of implementation and data processing were scored against version 2 of the Cochrane risk-of-bias tool for randomized trials for risk of bias. RESULTS The risk of bias arising from (1) the randomization process, (2) missing outcome data, and (3) selection of reported results was judged to be low. Risk of bias in (1) deviations from intended interventions (particularly due to the failure of masking) and (2) the measurement of the outcome, for example, through cleaning of the data, were judged to be high. CONCLUSION The use of power spectrum analysis of heart rate variability based on 5-minute recordings of echocardiogram pre-and post-intervention contained multiple sources of bias that were challenging to mitigate. Based upon these findings, power spectrum analysis of heart rate variability using these parameters may be ill-suited to the study of physiological effects of spinal manipulative therapy.

Osteopathic Manipulative Treatment Regulates Autonomic Markers in Preterm Infants: A Randomized Clinical Trial. Healthcare (Basel) 2022; 10:813.

Abstract
Osteopathic manipulative treatment (OMT) has been found to be effective in the context of premature infants. Nonetheless, no studies have investigated the immediate effects of OMT on heart rate variability (HRV). As altered HRV reflects poor or worsening newborn's clinical conditions and neurodevelopment, should OMT improve HRV fluctuations, it could become a relevant intervention for improving the care of preterm newborns. Therefore, this study aimed to evaluate whether OMT could affect HRV. The study was carried out at the Buzzi Hospital in Milan. From the neonatal intensive care unit, ninety-six preterm infants (41 males) were enrolled and were randomly assigned to one of two treatment groups: OMT or Static Touch. The infants were born at 33.5 weeks (±4.3) and had a mean birth weight of 2067 g (±929). The study had as primary outcome the change in the beat-to-beat variance in heart rate measured through root mean square of consecutive RR interval differences (RMSSD); other metrics were used as secondary and exploratory analyses. Despite the lack of statistically significant results regarding the primary outcomeand some study limitations, compared to static touch, OMT seemed to favor a parasympathetic modulation and improved HRV, which could reflect improvement in newborn's clinical conditions and development.

Abstract
OBJECTIVE The aim of this study was to examine the effect of osteopathic manipulative treatment (OMT) on anaerobic performance and lactate clearance in male athletes. METHODS This study was a double-blind, randomized, sham-controlled and crossover trial. Fourteen male athletes were volunteered to participate this study. All subjects visited to laboratory 3 times in total: familiarization session, test session 1, and test session 2, respectively. At the beginning of the study, the subjects were randomly divided into 2 groups: In sessions 1 and 2, (a) 30-minute OMT or sham treatment before Wingate anaerobic cycling test (WAnT), (b) 30-second WAnT test, and (c) 10-minute OMT or sham therapy between 5th and 15th minutes of passive rest after WAnT was applied to all subjects, respectively. In both groups blood samples were taken at rest and 5, 15 and 30 minute after the WAnT for the determination of lactate concentrations. RESULTS There was no significant differences in WAnT parameters such as peak power, mean power and fatigue index between the OMT and sham treatment. Blood lactate levels were significantly higher 5, 15 and 30 minute after the WAnT when compared to the rest and were lower 15 and 30 minute after the WAnT when compared to 5 minute after the WAnT in both groups (P < 0.05). In addition, blood lactate concentration was significantly lower in OMT than sham treatment at 15 and 30 minute after the WAnT (P < 0.05). CONCLUSIONS This study suggests that OMT may improve lactate clearance while not affecting anaerobic performance in athletes.
