Effect of osteopathic manipulative therapy on pulmonary function testing in children with asthma
The Journal of the American Osteopathic Association
Asthma is a leading cause of pediatric chronic illness, and poor disease control can lead to decreased quality of life and impaired academic performance. Although osteopathic manipulative treatment (OMT) has been shown to have positive effects on pulmonary function in adult patient populations, less is known about its impact in children.
The objective of this study was to evaluate changes in pulmonary function testing (PFT) in pediatric patients on the same day they received OMT compared with PFT in those who received usual care.
We recruited patients between the ages of 7–18 years with a diagnosis of asthma who were receiving routine care at a primary care asthma clinic and had undergone baseline spirometry. Patients were excluded if they met any of the following criteria: clinical indication for pre- and postbronchodilator spirometry on the day of their visit, albuterol use in the last 8 hours, oral steroid use in the previous 2 weeks, or diagnosis of asthma exacerbation in the previous 4 weeks. Eligible patients were then randomized to either an OMT or a control group. Patients in the OMT group were treated with rib raising and suboccipital release in addition to standard asthma care, while control group patients received standard care only. A second PFT was performed for patients in both groups at the end of the visit. OMT was performed by multiple osteopathic pediatric residents specifically trained for this study. Change in spirometry results (forced vital capacity [FVC], forced expiration volume in 1 second [FEV1], FVC/FEV1, and forced expiratory flow 25–75%) were then compared.
The study population included 58 patients: 31 (53.4%) were assigned to the OMT group and 27 (46.6%) were assigned to the standard of care group. Patients who received OMT had greater improvement in all spirometry values compared to the usual group; however, these changes were not statistically significant.

Neck pain with radiculopathy: A systematic review of classification systems
Musculoskeletal Science and Practice
Disparities in eligibility criteria for cervical radiculopathy (CR) in clinical trials have been acknowledged previously. The increasing use of CR related neck pain classification systems to inform eligibility criteria in clinical trials warrants evaluation.
The objective of this study was to evaluate existing neck pain classification systems for CR.
Systematic review and critical appraisal, reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.
Database searches were performed from inception until 31/7/2020. Neck pain classification systems containing CR as a component were included. Methodological quality of each classification system was assessed using seven measurement property domains and scored using a framework developed by Buchbinder and colleagues. Classification criteria for CR from classification systems assessed as moderate or good quality were narratively synthesised using inductive content analysis which consisted of selecting unit of analysis, open coding, grouping and categorisation.
Out of 19,975 references, 14,893 remained after elimination of duplicates with 17 articles reporting 11 classification systems included. Five moderate and one good quality classification systems were identified. Nine classification criteria for CR were derived, including dermatomal sensory deficit, positive Spurling’s test, positive upper limb tension test.
All classification systems had methodological limitations with Childs et al. (2008) classification system identified as good quality and most clinically useful. Future studies should investigate the reliability of Childs et al. (2008) classification system as it has the potential to further strengthen its methodological quality and clinical utility. The nine derived classification criteria can inform eligibility criteria in future trials.

Key indicators of repetitive overuse-induced neuromuscular inflammation and fibrosis are prevented by manual therapy in a rat model
BMC Musculoskeletal Disorders
We examined the effectiveness of a manual therapy consisting of forearm skin rolling, muscle mobilization, and upper extremity traction as a preventive treatment for rats performing an intensive lever-pulling task. We hypothesized that this treatment would reduce task-induced neuromuscular and tendon inflammation, fibrosis, and sensorimotor declines.
Sprague-Dawley rats performed a reaching and lever pulling task for a food reward, 2 h/day, 3 days/week, for 12 weeks, while simultaneously receiving the manual therapy treatment 3 times per week for 12 weeks to either the task-involved upper extremities (TASK-Tx), or the lower extremities as an active control group (TASK-Ac). Results were compared to similarly treated control rats (C-Tx and C-Ac).
Median nerves and forearm flexor muscles and tendons of TASK-Ac rats showed higher numbers of inflammatory CD68+ and fibrogenic CD206+ macrophages, particularly in epineurium, endomysium and epitendons than TASK-Tx rats. CD68+ and CD206+ macrophages numbers in TASK-Tx rats were comparable to the non-task control groups. TASK-Ac rats had more extraneural fibrosis in median nerves, pro-collagen type I levels and immunoexpression in flexor digitorum muscles, and fibrogenic changes in flexor digitorum epitendons, than TASK-Tx rats (which showed comparable responses as control groups). TASK-Ac rats showed cold temperature, lower reflexive grip strength, and task avoidance, responses not seen in TASK-Tx rats (which showed comparable responses as the control groups).
Manual therapy of forelimbs involved in performing the reaching and grasping task prevented the development of inflammatory and fibrogenic changes in forearm nerves, muscle, and tendons, and sensorimotor declines.

Exercise in patients with hip osteoarthritis — effects on muscle and functional performance: A randomized trial
Physiotherapy Theory and Practice
It is believed that clinical management of osteoarthritis should address muscle weakness to improve physical function and prevent disability and frailty. This sub-study investigated the effects of supervised progressive resistance training (RT), supervised Nordic Walking (NW), and unsupervised home-based exercise (HBE) on muscle and functional performance; and associations between these exercise-induced changes in persons with hip osteoarthritis.
Forty-two patients with hip osteoarthritis were recruited from a larger RCT (NCT01387867). All the groups (RT, n = 15; NW, n = 12; HBE, n = 15) exercised 1 h 3 times/week for 4 months. Quadriceps cross-sectional area (QCSA, MRI-determined); quadriceps strength (QMVC); leg extensor power (LEP); functional performance (chair stands (30sCS); stair climbs (TSC); and 6-minute walk (6MWT)) were assessed at baseline and 4 months.
Per protocol analyses (one-way ANOVA and Bonferroni test) showed significant between-group differences for improvements in QCSA in the most symptomatic leg favoring RT versus NW (2.3 cm2, 95% CI [0.6, 3.9]) and HBE (2.3 cm2 [0.8, 3.9]); and 30sCS (1.8 repetitions [0.2–3.3]), and 6MWT (35.1 m [3.5–66.7]) favoring NW versus HBE. Associations existed between exercise-induced changes in QCSA and QMVC (r = 0.366, p = .019) for the most symptomatic leg and between changes in 6MWT and QMVC (r = 0.320, p = .04) and LEP (r = 0.381, p = .01), respectively, for the least symptomatic leg.
Resistance training appeared effective for improving muscle mass, but less effective for improving muscle strength, power, and functional performance. Only exercise-induced changes in muscle strength and power of the least symptomatic leg, not the most symptomatic leg, were related to changes in functional performance.

Assessment of a taping method combined with manual therapy as a treatment of non-specific chronic low back pain — a randomized controlled trial
BMC Musculoskeletal Disorders
Chronic low back pain is the most frequent medical problem and the condition with the most years lived with disability in Western countries. The objective of this study was to assess a new treatment, Medi-Taping, which aims at reducing complaints by treating pelvic obliquity with a combination of manual treatment of trigger points and kinesio taping in a pragmatic RCT with pilot character.
One hundred ten patients were randomized at two study centers either to Medi-Taping or to a standard treatment consisting of patient education and physiotherapy as control. Treatment duration was 3 weeks. Measures were taken at baseline, end of treatment and at follow-up after 2 months. Main outcome criteria were low back pain measured with VAS, the Chronic Pain Grade Scale (CPGS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ).
Patients of both groups benefited from the treatment by medium to large effect sizes. All effects were pointing towards the intended direction. While Medi-Taping showed slightly better improvement rates, there were no significant differences for the primary endpoints between groups at the end of treatment (VAS: mean difference in change 0.38, 95-CI [− 0.45; 1.21] p = 0.10; ODQ 2.35 [− 0.77; 5.48] p = 0.14; CPGS − 0.19 [− 0.46; 0.08] p = 0.64) and at follow-up. Health-related quality of life was significantly higher (p = .004) in patients receiving Medi-Taping compared to controls.
Medi-Taping, a purported way of correcting pelvic obliquity and chronic tension resulting from it, is a treatment modality similar in effectiveness to complex physiotherapy and patient education.

The effects of myofascial release technique for patients with low back pain: A systematic review and meta-analysis
Complementary Therapies in Medicine
The purpose of this meta-analytic review was to quantitatively examine the effects of myofascial release technique (MFR) on pain intensity, back disability, lumbar range of motion, and quality of life in patients with low back pain (LBP).
Potential articles were retrieved using five electronic databases (Web of Science, PubMed, Scopus, China National Knowledge Infrastructure, and Wanfang). The search period was from inception to January 27, 2021. Two researchers independently completed record retrieval and selection, data extraction, and methodological quality assessment. Randomized controlled trials (RCTs) assessing the effect of MFR on pain intensity, back disability, lumbar range of motion, and quality of life in LBP patients were included. Pooled effect sizes were calculated using random effects models and 95% confidence interval (95% CI).
Data from eight RCTs (386 patients with back pain) meeting the inclusion criteria were extracted for meta-analysis with methodological quality assessment scores ranging from 6 to 10. Compared to the control intervention, MFR induced significant decrease in back disability (SMD = −0.35, 95% confidence interval [CI] = −0.68, –0.02, P = 0.04, I² = 46%, n = 284). MFR induced non-significant decrease in the pain intensity (SMD = −0.12, 95% confidence interval[CI] = −0.35, 0.11, P = 0.32, I² = 0%, n = 294), non-significant improvement in quality of life (SMD = −0.09, 95% confidence interval [CI] = −0.46, 0.28, P = 0.62, I² = 0%, n = 114), and non-significant improvement in lumbar range of motion (Flexion SMD = 0.57,95% confidence interval [CI] = −0.09, 1.24, P = 0.09, I² = 54%, n = 80) (Extension SMD = 0.68, 95% confidence interval[CI] = −0.72, 2.08, P = 0.34, I² = 89%, n = 80) (Right flexion SMD = 0.05, 95% confidence interval[CI] = −0.90, 0.99, P = 0.92, I² = 78%, n = 80) (Left flexion SMD = 0.14, 95% confidence interval[CI] = −0.59, 0.88, P = 0.70, I² = 64%, n = 80).
The findings suggest that MFR can improve the effect of physical therapy alone and exercise therapy alone, and that MFR can be an effective adjuvant therapy. Meta-analysis showed that MFR has a significant effect on reducing back disability in patients with low back pain, but no significant effect on reducing pain intensity, improving quality of life, and improving lumbar range of motion.
