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.

[PMID: 37789996 PMCID: PMC10544646 DOI: 10.7759/cureus.44525] [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: 12/20/2022] [Accepted: 09/01/2023] [Indexed: 10/05/2023] Open
Abstract
Repeated obstruction and closure of the upper airway, sporadic hypoxic episodes, and sympathetic activity are symptoms of obstructive sleep apnea (OSA). Obstructive sleep apnoea is due to a combination of altered upper airway structure and muscular function, a low arousal threshold and increased loop gain. Although recurrent upper airway (UA) collapse during sleep is the most frequent clinical hallmark of OSA, the exact cause of this collapse is unknown. Furthermore, while continuous positive airway pressure aids in the management of OSA, many patients find it intolerable. As a result, a better knowledge of the causes of OSA may result in more effective treatments. We did a review of randomized controlled trials that were done in this regard in the last 10 years and whose full-text version is available on the PubMed database. A total of 20 articles were finalized for review after applying our criteria. The articles have proposed different theories regarding the anatomical basis responsible for obstructive sleep apnoea. The theories proposed by different studies in the last decade include reduced genioglossus and hypoglossal nerve activity, the pharyngeal muscles' failure to keep the airway open or tighten it, tonsils and adenoid hypertrophy, an oversensitive ventilatory control system and low respiratory arousal threshold, mandibular position, pharyngeal muscles' high sympathetic drive, cephalometric alterations such as mandibular and hyoid bone position and the length of the soft palate, obesity, and neck fat and fluid re-distribution in the body, from the lower to the upper parts while reclining. Given the diverse etiological characteristics of OSA patients and to increase our knowledge of the condition, additional study into this group is required. Filling any knowledge gaps that may exist in the anatomical basis of the onset of OSA is the main objective of this review paper.

Osteopathic Manipulation of the Sphenopalatine Ganglia Versus Sham Manipulation, in Obstructive Sleep Apnoea Syndrom: A Randomised Controlled Trial. J Clin Med 2021; 11:jcm11010099. [PMID: 35011840 PMCID: PMC8745154 DOI: 10.3390/jcm11010099] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 12/06/2021] [Accepted: 12/21/2021] [Indexed: 11/16/2022] Open
Abstract
(1) Background: osteopathic manipulation of the sphenopalatine ganglia (SPG) blocks the action of postganglionic sensory fibres. This neuromodulation can reduce nasal obstruction and enhance upper airway stability. We investigated the manipulation of the SPG in 31 patients with obstructive sleep apnoea syndrome (OSAS); (2) Methods: Randomised, controlled, double-blind, crossover study. Participants received active (AM), then sham manipulation (SM), or vice versa. The primary endpoint was apnoea-hypopnoea index (AHI). Secondary endpoints were variation of nasal obstruction evaluated by peak nasal inspiratory flow (PNIF) and upper airways stability evaluated by awake critical closing pressure [awake Pcrit]), at 30 min and 24 h. Schirmer’s test and pain were assessed immediately post-manipulation. Tactile/gustatory/olfactory/auditory/nociceptive/visual sensations were recorded. Adverse events were collected throughout. (3) Results: SPG manipulation did not reduce AHI (p = 0.670). PNIF increased post-AM but not post-SM at 30 min (AM-SM: 18 [10; 38] L/min, p = 0.0001) and 24 h (23 [10; 30] L/min, p = 0.001). There was no significant difference on awake Pcrit (AM-SM) at 30 min or 24 h). Sensations were more commonly reported post-AM (100% of patients) than post-SM (37%). Few adverse events and no serious adverse events were reported. (4) Conclusions: SPG manipulation is not supported as a treatment for OSAS but reduced nasal obstruction. This effect remains to be confirmed in a larger sample before using this approach to reduce nasal congestion in CPAP-treated patients or in mild OSAS.

Abstract
BACKGROUND AND AIM Patients with chronic musculoskeletal pain diseases (CMPDs) often use osteopathic medicine (OM), although the changes in patients with pain diseases are still insufficiently investigated. This study aimed to observe changes along and after OM in addition to routine care on pain, functioning, and quality of life in patients with four CMPDs. METHODS In this observational trial with follow-up, patients suffering from chronic neck pain (CNP, n = 10), chronic low back pain (CLBP, n = 10), chronic shoulder pain (CSP, n = 10), or chronic knee pain (CKP, n = 10) received up to six OM sessions in addition to routine care. RESULTS A total of 40 patients (73% female, mean age 47.7 ± 8.3 years, mean pain intensity 59.4 ± 12.5 mm, measured by a visual analog scale [VAS] 0-100 mm) were included. After 26 weeks, there was an improvement in the VAS pain score in the whole population (mean difference to baseline -33.1 mm [95% CI -40.5 to -25.7]), as well in the patients with the four diseases: CNP (-33.7 mm [-54.7 to -12.6]), CLBP (-28.2 mm [-47.9 to -8.4]), CSP (-32.4 [-46.8 to -18.0]), and CKP (-38.1 mm [-49.1 to -27.0]). Regarding disease-specific outcomes, we found improvements in CNP, as measured by the neck disability index (scale 0-50; mean difference -3.6 [-9.0 to 1.9]), CLBP, as measured by the low back pain rating scale (scale 0-60; -3.4 [-12.5 to 5.7]), CSP, as measured by the disabilities of the arm, shoulder and hand score (scale 0-100; -13.4 [-23.1 to -3.7]), and CKP, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (scale 0-96; -13.0 [-23.5 to -2.5]). These improvements persisted through week 52. No adverse events were observed. CONCLUSION The study observed beneficial changes along and after the OM treatment in addition to routine care in patients with four different CMPDs. High-quality, multicenter randomized controlled trials are strongly needed to compare the effectiveness of OM and standard care interventions in treating CMPDs in the future. We have provided sufficient data for sample size calculations for these trials.

Abstract
AIM This study aims to evaluate the efficacy of sphenopalatine ganglion block (SPGB) on postoperative edema and ecchymosis for the patients undergoing septorhinoplasty (SRP). METHODS In the study, a total number of 55 participant patients (40% male and 60% female, aged between 18 and 42 years) undergoing hump resection and osteotomies were allocated into 2 groups. The SPGB (+) group consisted of 27 patients who underwent SPGB, while the SPGB (-) group consisted of 28 patients who underwent SRP without SPGB. On the first, third, and seventh postoperative days (POD1, POD3, POD7), the score marks of periorbital edema and ecchymosis of the patients were evaluated. Additionally, postoperative upper eyelid edema and upper eyelid ecchymosis as well as lower eyelid edema, and lower eyelid ecchymosis on POD1, POD3, POD7 were evaluated. A comparison with regard to intraoperative bleeding, surgical field, and operation time between the 2 groups was also conducted. RESULTS Upper eyelid edema, upper eyelid ecchymosis, lower eyelid edema, lower eyelid ecchymosis on POD 1, 3, 7 were found to be significantly lower in SPGB (+) group in comparison to SPGB (-) group (P < 0.001). Intraoperative blood loss and surgical field were found to be significantly lower in SPGB group (+) than in SPGB (-) group (P < 0.00). The operation time was not found statistically significant between the 2 groups (P = 0.212). CONCLUSION Sphenopalatine ganglion block is a safe and effective way of reducing postoperative edema and ecchymosis after SRP. Besides, it provides a better surgical field and reduced bleeding intraoperatively.

Abstract
Historically, osteopathic principles have focused on the appropriate drainage of cranial structures to relieve symptoms of rhinitis, which include nasal congestion, anterior/posterior rhinorrhea, sneezing, and itching. Allergic rhinitis is primarily an aberrant immunologic reaction caused by cytokines secreted from lymphocytes that traverse the lymphatic pathway throughout the body. Several studies have documented that, when manipulated, the lymphatic system enhanced the motion of these lymphocytes to important immune structures in both human and animal models. Additionally, modulation of both sympathetic and parasympathetic outflow has been found either to inhibit or enhance secretion and/or drainage of important allergic sites. Osteopathic approaches to rhinitis play an effective role in the comprehensive management of rhinitis, and techniques based on these approaches are therapeutic options for rhinitis. This article provides an up-to-date literature review about the management of rhinitis using the 5 models of osteopathic medicine: biomechanical, respiratory-circulatory, metabolic, neurologic, and behavioral.

Mandibular advancement reveals long-term suppression of breathing discomfort in patients with obstructive sleep apnea syndrome. Respir Physiol Neurobiol 2019; 263:47-54. [PMID: 30872167 DOI: 10.1016/j.resp.2019.03.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 03/08/2019] [Accepted: 03/10/2019] [Indexed: 02/07/2023]
Abstract
Obstructive sleep apnoea syndrome (OSAS) patients do not report breathing discomfort in spite of abnormal upper airway mechanics. We studied respiratory sensations in OSAS patients without and with mandibular advancement device (MAD). Fifty-seven moderate to severe non obese OSAS patients were asked about breathing discomfort using visual analogue scales (VAS) in the sitting position (VAS-1), after lying down (VAS-2), then with MAD (VAS-3). Awake critical closing pressure (awake Pcrit) was measured in 15 patients without then with MAD. None of the patients reported breathing discomfort when sitting but 19 patients (33%) did when lying (VAS-2: -20% or less). A feeling of "easier breathing" with MAD was observed and was more marked in patients reporting breathing discomfort when supine (VAS-3: +66.0% [49.0; 89.0]) than in those not doing so (VAS-3: +28.5% [1.0; 56.5], p = 0.007). MAD-induced change in awake Pcrit was correlated to VAS-3. In conclusion, MAD revealed "latent dyspnea" related to the severity of upper airways mechanics abnormalities in OSAS patients.
