Changes in Cytokines, Sensory Tests, and Self-reported Pain Levels After Manual Treatment of Low Back Pain.

STUDY DESIGN: Unbalanced 3-factor design with repeated measures on 1 factor. OBJECTIVE: To determine the effect of manual treatment (MT) on cytokine and pain sensations in those with and without low back pain (LBP). SUMMARY OF BACKGROUND DATA: Evidence suggests that MT reduces LBP but by unknown mechanisms. Certain cytokines have been elevated in patients with LBP and may be affected by MT. METHODS: Participants aged 20-60 years with chronic LBP or without LBP were recruited and randomly assigned to MT, sham ultrasound treatment, or no treatment groups. Venous blood samples were collected and pain levels assessed at baseline, 1 hour later, and 24 hours later. Blood was analyzed for interleukin (IL)-1ß, IL-6, tumor necrosis factor-α, and C-reactive protein. Pain levels were measured by pressure pain threshold (PPT), mechanical detection threshold (MDT), dynamic mechanical allodynia, and self-report. RESULTS: Forty (30 women, age 36±11 y) participants completed the study, 33 with LBP (13 MT, 13 sham ultrasound treatment, and 7 no treatment) and 7 without LBP. Participants with or without LBP could not be differentiated on the basis of serum cytokine levels, PPT, or MDT (P≥0.08). There were no significant differences between the groups at 1 hour or 24 hours on serum cytokines, PPT, or MDT (P≥0.07). There was a significant decrease from baseline in IL-6 for the no treatment (LBP) group (P=0.04), in C-reactive protein for the sham ultrasound treatment group (P=0.03), in MDT for all 3 LBP groups (P≤0.02), and in self-reported pain for the MT and sham ultrasound treatment groups (P=0.03 and 0.01). CONCLUSIONS: Self-reported pain was reduced with MT and sham ultrasound treatment 24 hours after treatment, but inflammatory markers within venous circulation and quantitative sensory tests were unable to differentiate between study groups. Therefore, we were unable to characterize mechanisms underlying chronic LBP.

Epidemiology and Health-Related Quality of Life in Hypoparathyroidism in Norway.

OBJECTIVE: The epidemiology of hypoparathyroidism (HP) is largely unknown. We aimed to determine prevalence, etiologies, health related quality of life (HRQOL) and treatment pattern of HP. METHODS: Patients with HP and 22q11 deletion syndrome (DiGeorge syndrome) were identified in electronic hospital registries. All identified patients were invited to participate in a survey. Among patients who responded, HRQOL was determined by Short Form 36 and Hospital Anxiety and Depression scale. Autoantibodies were measured and candidate genes (CaSR, AIRE, GATA3, and 22q11-deletion) were sequenced for classification of etiology. RESULTS: We identified 522 patients (511 alive) and estimated overall prevalence at 102 per million divided among postsurgical HP (64 per million), nonsurgical HP (30 per million), and pseudo-HP (8 per million). Nonsurgical HP comprised autosomal dominant hypocalcemia (21%), autoimmune polyendocrine syndrome type 1 (17%), DiGeorge/22q11 deletion syndrome (15%), idiopathic HP (44%), and others (4%). Among the 283 respondents (median age, 53 years [range, 9-89], 75% females), seven formerly classified as idiopathic were reclassified after genetic and immunological analyses, whereas 26 (37% of nonsurgical HP) remained idiopathic. Most were treated with vitamin D (94%) and calcium (70%), and 10 received PTH. HP patients scored significantly worse than the normative population on Short Form 36 and Hospital Anxiety and Depression scale; patients with postsurgical scored worse than those with nonsurgical HP and pseudo-HP, especially on physical health. CONCLUSIONS: We found higher prevalence of nonsurgical HP in Norway than reported elsewhere. Genetic testing and autoimmunity screening of idiopathic HP identified a specific cause in 21%. Further research is necessary to unravel the causes of idiopathic HP and to improve the reduced HRQOL reported by HP patients.

A systematic review and meta-synthesis of the impact of low back pain on people's lives.

BACKGROUND: Low back pain (LBP) is a common and costly problem that many interpret within a biopsychosocial model. There is renewed concern that core-sets of outcome measures do not capture what is important. To inform debate about the coverage of back pain outcome measure core-sets, and to suggest areas worthy of exploration within healthcare consultations, we have synthesised the qualitative literature on the impact of low back pain on people's lives. METHODS: Two reviewers searched CINAHL, Embase, PsycINFO, PEDro, and Medline, identifying qualitative studies of people's experiences of non-specific LBP. Abstracted data were thematic coded and synthesised using a meta-ethnographic, and a meta-narrative approach. RESULTS: We included 49 papers describing 42 studies. Patients are concerned with engagement in meaningful activities; but they also want to be believed and have their experiences and identity, as someone 'doing battle' with pain, validated. Patients seek diagnosis, treatment, and cure, but also reassurance of the absence of pathology. Some struggle to meet social expectations and obligations. When these are achieved, the credibility of their pain/disability claims can be jeopardised. Others withdraw, fearful of disapproval, or unable or unwilling to accommodate social demands. Patients generally seek to regain their pre-pain levels of health, and physical and emotional stability. After time, this can be perceived to become unrealistic and some adjust their expectations accordingly. CONCLUSIONS: The social component of the biopsychosocial model is not well represented in current core-sets of outcome measures. Clinicians should appreciate that the broader impact of low back pain includes social factors; this may be crucial to improving patients' experiences of health care. Researchers should consider social factors to help develop a portfolio of more relevant outcome measures.

Osteopathic medical students' beliefs about osteopathic manipulative treatment at 4 colleges of osteopathic medicine.

CONTEXT: Osteopathic manipulative treatment (OMT) is a distinctive and foundational aspect of osteopathic medicine. Several studies have reported a decline in the use of OMT by practicing osteopathic physicians, but the reasons for this decline have not been fully investigated. OBJECTIVE: To investigate osteopathic medical students' attitudes and beliefs regarding osteopathic philosophy, including OMT. METHODS: A self-administered, 21-item, electronic questionnaire developed specifically for the current study was distributed to first- and second-year osteopathic medical students at 4 colleges of osteopathic medicine. The questionnaire contained items addressing student attitudes toward osteopathic philosophy, including OMT; perceptions of osteopathic predoctoral education; and plans for integrating OMT into future practice. RESULTS: Of 1478 questionnaires sent, 491 students completed the questionnaire for an overall response rate of 33%. Analysis of student responses revealed that a majority of first- and second-year osteopathic medical students (95%-76%, depending on the question asked) expressed agreement with osteopathic philosophy. Students who reported prior exposure to OMT had higher levels of agreement with osteopathic philosophy statements (P<.04) and with the intention to use OMT (P<.02) than students with no prior exposure. However, students who were drawn to an osteopathic medical school by the desire to become a physician regardless of degree reported lower levels of agreement with osteopathic philosophy and the intention to use OMT. Students' levels of agreement with osteopathic philosophy and intention to use OMT varied significantly based on the school that they attended, their current year of study, and whether or not they were participating in clinical rotations. CONCLUSION: The reason why a student decided to study osteopathic medicine was strongly associated with the level of agreement with osteopathic philosophy and the intention to use OMT in future practice. Prior experience receiving OMT, the medical school that a student attends, and the current year of study appear to be related to the students' levels of agreement with osteopathic philosophy and intention to use OMT.

Resting electromyographic activity of deep thoracic transversospinalis muscles identified as abnormal with palpation.

CONTEXT: In the 1940s, osteopathic researchers suggested that paraspinal tissue abnormality was associated with spontaneous muscle activity, but few studies have since re-examined these reports. OBJECTIVE: To determine whether abnormal motor activity plays a role in deep paraspinal tissues that appear abnormal to palpation. METHODS: Using an observational study design, the PVG of participants with thoracic pain were palpated by two examiners for consensus on the most marked level of tissue abnormality. Dual fine-wire, intramuscular electrodes were inserted into the deep transversospinalis (multifidus, rotatores) muscles at the abnormal level and at two normal sites (above and below the abnormal level). Surface electrodes were placed over the erector spinae muscles adjacent to each intramuscular electrode site. Electromyography signals were recorded during initial prone resting, three maximal voluntary isometric contractions (MVIC), and a second prone resting. The area under the curve for a 2-second period was analyzed for each condition, and values were normalized and reported as a percentage of MVIC. Data were analyzed using a 2-factor repeated-measures analysis of variance. RESULTS: Twenty-five participants with mean (SD) thoracic pain of 3.3 (1.9) on a 0 to 10 visual analog pain scale completed the study protocol. There were no statistically significant differences in normalized resting activity between the three intramuscular sites (P=.25) or between the three surface sites (P=.33). Substantial variability in normalized resting activity at each of the three intramuscular sites was evident (mean [SD] percent of MVIC: abnormal 7.83 [8.76]; normal 9.47 [8.45], 6.65 [7.39]). No statistically significant differences existed in the intramuscular EMG values between the two resting baseline periods (P=.10). CONCLUSION: The lack of statistically significant differences between EMG activity at the abnormal and normal paraspinal sites suggests that factors other than muscle activity are responsible for the apparent abnormality of these tissues to palpation. Investigation of these regions for increased tissue fluid and inflammatory mediators is recommended.

Clinical and research protocol for osteopathic manipulative treatment of elderly patients with pneumonia.

Pneumonia in elderly patients is a major public health concern because of greater morbidity and mortality and longer hospital stays relative to younger populations. Based on the premise that osteopathic manipulative treatment (OMT) is beneficial in the management of pulmonary infections, the Multicenter Osteopathic Pneumonia Study in the Elderly (MOPSE) was designed as a prospective randomized controlled trial to evaluate the efficacy of OMT as an adjunct to the current pharmacologic treatment of elderly patients hospitalized for pneumonia. The protocol developed for MOPSE has its origins in early osteopathic medical literature at a time when effective antibiotic therapy was unavailable and osteopathic physicians relied on physical examination and empiric reasoning to develop treatment strategies and OMT techniques to improve host defenses against pneumonia. The present paper reviews the early osteopathic medical literature to identify the reasoning behind the OMT techniques that are the basis for the design of the MOPSE protocol. Likewise, the contemporary medical literature relevant to the protocol is reviewed. Finally, a description of the study design and the OMT and light touch (sham) protocols used in MOPSE are provided.
