Étude exploratoire de la santé musculo-squelettique du rachis d’étudiants en ostéopathie

BackgroundDuring their training, students in osteopathy regularly undergo spinal manipulation exercises. This exposes the students’ spine to unskilled gestures performed by their colleagues learning spinal manipulation. Discomfort, muscle soreness or moderate pain following spinal manipulations lasting two or three days are commonly reported. In addition, some students may have ongoing spinal musculoskeletal disease (SMSD) during their studies. The purpose of this study was to evaluate the prevalence of SMSDs and their maximum intensity in a population of osteopathy students and to determine whether individual differences exist.MethodAn exploratory cross-sectional study took place over three years. Data were collected by means of a self-administrated standardised questionnaire screening for MSD: the Nordic questionnaire.ResultsThere were 733 exploitable questionnaires, giving an average response rate of 91.5%. Average prevalence of SMSD was 98.4% during the last 12 months. Average maximum intensity perceived was 6/10 and 45% of students experienced an intense SMSD (scored between 7 and 10/10). Variation of the maximum intensity of SMSD between “before osteopathy studies” and “the last 12 months” was 1.2/10. This variation was influenced by the number of days students were manipulated during a week (p < 0.0001). On average, students underwent manipulation three days a week.ConclusionThis study confirms the important prevalence of SMSD among osteopathy students. This result led us to carry out a qualitative study for exploring students’ conceptions in health and spinal manipulative practices.

Subthalamic neuron activity related to tremor and movement in Parkinson's disease

Single cell activity recorded in the subthalamic nucleus (STN) of Parkinson's patients and the effect of tremor, passive and voluntary movement upon the same cells are described. Three types of cells were distinguished by the pattern of discharge: tonic, phasic and rhythmic. They all demonstrated high mean firing rates (65, 59 and 69 Hz, respectively). Simultaneous recordings of muscle activity and tremor helped in defining cell activity. The implantation of the definitive stimulating electrode in the patients was based on the number of STN cells related to tremor, active and passive movements (mean = 68%) along the track chosen. Cells were related to tremor (n = 21; 11%), modified the discharge with differences in the amplitude of tremor (n = 4), and changed the rate and pattern when tremor stopped spontaneously or artificially (n = 6). Movement-related cells (n = 97; 51%) showed a cyclic activity correlated with phases of the movement, or modified the firing rate along the performance of the movement. Tremor and movement-related cells (n = 11; 6%) revealed an interesting sensory-motor integrative function.

The yin and yang faces of the mitochondrial deacetylase sirtuin 3 in age-related disorders

Aging, the most important risk factor for many of the chronic diseases affecting Western society, is associated with a decline in mitochondrial function and dynamics. Sirtuin 3 (SIRT3) is a mitochondrial deacetylase that has emerged as a key regulator of fundamental processes which are frequently dysregulated in aging and related disorders. This review highlights recent advances and controversies regarding the yin and yang functions of SIRT3 in metabolic, cardiovascular and neurodegenerative diseases, as well as the use of SIRT3 modulators as a therapeutic strategy against those disorders. Although most studies point to a protective role upon SIRT3 activation, there are conflicting findings that need a better elucidation. The discovery of novel SIRT3 modulators with higher selectivity together with the assessment of the relative importance of different SIRT3 enzymatic activities and the relevance of crosstalk between distinct sirtuin isoforms will be pivotal to validate SIRT3 as a useful drug target for the prevention and treatment of age-related diseases.     

Isometric osteopathic manipulation influences on cervical ranges of motion and correlation with osteopathic palpatory diagnosis: A randomized trial

IntroductionIsometric manipulation is a current practice in osteopathy and treatment benefits have been reported in the literature. Such benefits could be assessed using experimental non-invasive cervical mobility measurements. The main objective was to quantitatively measure the effects of isometric manipulation on principal and compensatory cervical motions.Methods101 healthy volunteers were included in this study. 51 healthy volunteers selected randomly underwent the experimental protocol before and after isometric treatment and were compared to 50 healthy volunteers who underwent a placebo treatment. Osteopathic diagnosis was performed on each healthy volunteer before and after the treatment. The experimental protocol included measurements by a motion capture system focusing on principal range of motion and compensatory motions.ResultsIn both the isometric and the placebo sample, respectively including 51 (age: 29.2 ± 8.1, BMI: 22.2 ± 3.5) and 50 healthy volunteers (age: 27.4 ± 6.8, BMI: 22.9 ± 2.8), a pre-treatment diagnosis revealed a light cervical dysfunction in all subjects, mainly in levels C3 and C4. Altered ranges of motion thresholds (C3/C4 alterations) were identified: 113.2° for flexion, 130.0° for rotation and 90.2° for lateral flexion.After manipulations, the volunteers who underwent the isometric treatment presented a slight increase in amplitude for lateral flexion (p < 0.04), which was not found in the volunteers who underwent the placebo treatment. Compensatory motions showed differences pre and post isometric treatment without reaching significant values.ConclusionPrincipal ranges of motion were found significantly higher after osteopathic treatment when compared to the placebo treatment. Osteopathic palpatory diagnosis showed significant correlation with range of motions before treatment.     

Treatment of panic disorder by trigeminal nerve manipulation: A case series

This is a report on two cases of patients with acute severe panic disorder relieved of their symptoms by manual manipulations of the trigeminal nerve's alveolar branches. The manipulations were performed via the oral cavity during one session, or two consecutive sessions less than a week apart. No other effective treatment was administered prior, concurrently or since the time of the treatment. The recovery from panic disorder was immediate and lasted for the entire period of observation of three years. The authors used the same procedure and achieved identical clinical results treating ten other clients over a period of three years. This was not a planned experiment or randomized study. Rather, this report presents clinical evidence and the authors' hypothesis based on clinical data and literature review.     

Osteopathic manipulative treatment combined with exercise improves pain and disability in individuals with non-specific chronic neck pain: A pragmatic randomized controlled trial

PurposeTo determine effectiveness of osteopathic manipulative treatment combined with stretching and strengthening exercises in the cervical region on pain and disability in individuals with non-specific chronic neck pain.Methods90 adults with non-specific chronic neck pain were randomized to either exercises group (EG, n = 45) or osteopathic manipulative treatment associated with exercises group (OMT/EG, n = 45). The primary outcomes were obtained by the use of Numeric Pain-Rating Scale (NPRS), Pressure Pain Threshold (PPT) and Neck Disability Index (NDI). Secondary outcomes included range of motion (ROM) for cervical spine rotation, Fear-Avoidance Beliefs Questionnaire Work/Physical Activity (FABQ-W/PA) and Pain-self efficacy at two different moments: baseline and 4 weeks after the first treatment. Techniques and dosages of OMT were selected pragmatically by a registered osteopath. Generalized Estimating Equations model (GEE), complemented by the Least Significant Difference (LSD) and the intention-to-treat analysis, was used to assess the clinical outcomes.ResultsAnalysis with GEE indicated that OMT/EG reduced pain and disability more than the EG alone after 4 weeks of treatment with statistically significant difference (p < 0,05), as well as cervical active rotation was significantly improved (p = 0.03). There were no between-group differences observed in Pressure Pain Threshold (PPT) measure, Fear-Avoidance Beliefs Questionnaire and Pain-self efficacy.ConclusionThe association between OMT and exercises reduces pain and improves functional disability more than only exercise for individuals with non-specific chronic neck pain.     

Effectiveness of mechanical diagnosis and therapy in patients with non-specific chronic low back pain: a literature review with meta-analysis

ObjectiveTo determine the effectiveness of mechanical diagnosis and therapy (MDT) in patients with chronic low back pain (CLBP) compared to other traditional physical therapy interventions.MethodsRandomized controlled trials investigating the effect of MDT compared to other traditional physical therapy interventions in individuals with CLBP were considered eligible. For the purpose of this review, MDT was compared to active and passive physical therapy interventions. Independent reviewers assessed the eligibility of studies, extracted data, and assessed the risk of bias. The primary outcomes investigated were pain and disability.ResultsFourteen studies were included in the review. Of these, 11 provided data to be included in the meta-analyses. Our findings showed that MDT was no more effective in decreasing pain (standardized mean difference [SMD] = 0.01, 95% confidence interval [CI]: ?0.44, 0.46) and disability (SMD = 0.08, 95% CI: ?0.53, 0.68) than other active treatments. Similar results were found when comparing MDT to other passive treatments for pain (SMD = ?0.39, 95% CI: ?0.90, 0.11) and disability (SMD = ?0.13, 95% CI: ?0.29, 0.03).ConclusionThere is low to moderate quality evidence that MDT is not superior than other traditional physical therapy interventions in improving pain and disability in people with CLBP.
