Manual therapy for asthma.

BACKGROUND: A variety of manual therapies with similar postulated biologic mechanisms of action are commonly used to treat patients with asthma. Manual therapy practitioners are also varied, including physiotherapists, respiratory therapists, chiropractic and osteopathic physicians. A systematic review across disciplines is warranted. OBJECTIVES: To evaluate the evidence for the effects of manual therapies for treatment of patients with bronchial asthma. SEARCH STRATEGY: Trials were searched in computerized general (EMBASE, CINAHL and MEDLINE) and specialized databases (Cochrane Complementary Medicine Field, Cochrane Rehabilitation Field, ICL, and MANTIS). In addition, bibliographies from included studies were assessed, and authors of known studies were contacted for additional information about published and unpublished trials. Date of most recent search: December 1998. SELECTION CRITERIA: Trials were included if they: (1) were randomised; (2) included asthmatic children or adults; (3) examined one or more types of manual therapy; and (4) included clinical outcomes. DATA COLLECTION AND ANALYSIS: All three reviewers independently extracted data and assessed trial quality using a standard form. MAIN RESULTS: From an initial 316 unique citations, 48 full text articles were retrieved and evaluated, which resulted in nine citations to five RCTs (290 patients) suitable for inclusion. Trials could not be pooled statistically because studies that addressed similar interventions used disparate patient groups or outcomes. The methodological quality of one of two trials examining chiropractic manipulation was good and neither trial found significant differences between chiropractic spinal manipulation and a sham manoeuvre on any of the outcomes measured. Quality of the remaining three trials was poor. One small trial compared massage therapy with a relaxation control group and found significant differences in many of the lung function measures obtained. However, this trial had poor reporting characteristics and the data have yet to be confirmed. One small trial compared chest physiotherapy to placebo and one small trial compared footzone therapy to a no treatment control. Neither trial found differences in lung function between groups. REVIEWER'S CONCLUSIONS: There is insufficient evidence to support the use of manual therapies for patients with asthma. There is a need to conduct adequately-sized RCTs that examine the effects of manual therapies on clinically relevant outcomes. Future trials should maintain observer blinding for outcome assessments, and report on the costs of care and adverse events. Currently, there is insufficient evidence to support or refute the use of manual therapy for patients with asthma.

Plaque removal efficacy of a prototype manual toothbrush versus an ADA reference manual toothbrush with and without dental floss.

OBJECTIVE: The objective of this study was to compare the plaque removal efficacy of a prototype manual Deep Clean toothbrush versus an American Dental Association (ADA) manual toothbrush and the ADA manual toothbrush in conjunction with floss. METHODS: This study was a randomized, examiner-blind, six-period cross-over, single-center study conducted in 60 adult subjects that examined plaque removal with a prototype Deep Clean manual toothbrush, an ADA reference manual toothbrush, and an ADA reference manual toothbrush followed by floss. During the course of this study, subjects used each treatment two times. Plaque was scored before and after brushing using the Rustogi Modification of the Navy Plaque Index. A mixed model analysis of covariance (ANCOVA) for a crossover design with baseline plaque score as the covariate was applied to the baseline minus one-minute post-brushing differences in average whole-mouth plaque scores. Supplemental analyses were also performed using the ANCOVA model separately for average gingival margin scores and for average interproximal scores, using the appropriate baseline score as the covariate. All comparisons were two-sided at the 0.05 level of significance. RESULTS: The prototype Deep Clean manual toothbrush delivered an adjusted (via ANCOVA) mean difference between baseline and post-brushing plaque scores of 0.245, while the ADA manual toothbrush plus floss delivered an adjusted mean difference of 0.207 versus 0.196 for the ADA manual toothbrush alone. The prototype Deep Clean manual toothbrush demonstrated a statistically significantly greater reduction in plaque than the ADA manual toothbrush plus floss (p<0.001), which in turn had a statistically significantly greater reduction in plaque than the ADA manual toothbrush alone (p<0.001). The prototype Deep Clean manual toothbrush group had, on average, 25.2% and 18.3% greater plaque removal scores than the ADA manual toothbrush alone and the ADA manual toothbrush plus floss groups, respectively. Results for the interproximal and gingival margin regions also demonstrated statistically significantly (p<0.001) greater plaque removal for the prototype Deep Clean manual toothbrush group relative to the other groups. CONCLUSIONS: The prototype manual Deep Clean toothbrush was found to deliver greater plaque removal by 25.2% and 18.3% compared to the control manual toothbrush group (ADA reference manual toothbrush) and ADA manual toothbrush plus floss group.

The health impact of smoking in manual and non-manual social class men and women: a test of the Blaxter hypothesis.

Blaxter has hypothesized that harmful behavioral habits like smoking have a greater impact on health in the non-manual than in the manual social classes, possibly because other adverse exposures have a more important role in the manual social classes. However, the outcome measure used was a composite measure of physiological indices of morbidity and the relevance of this to other health problems is uncertain. We have therefore investigated the effect of smoking on mortality, to test whether the risk of death associated with smoking differs between manual and non-manual social classes. Data on 6831 men and 7993 women, aged 45-64 when screened in the Renfrew and Paisley study, a large prospective observational study in the West of Scotland, have been analyzed. All cause mortality rate ratios for smokers compared with never smokers have been calculated within manual and non-manual social classes. Although the age adjusted rate ratios are slightly higher among the non-manual men and women (2.19 [1.83-2.61] versus 1.92 [1.71-2.17] for non-manual and manual men respectively, and 1.75 [1.54-1.99] versus 1.65 [1.50-1.82] for non-manual and manual women), this difference between social classes is not statistically significant (p-values for test of difference 0.26 and 0.47 for men and women respectively). When additionally adjusted for other risk factors, cardiorespiratory symptoms and deprivation, this picture remained the same (p-values for test of difference are 0.41 and 0.50 for men and women respectively). Similar results were found when the cohort was divided by deprivation categories rather than social classes or when smoking related mortality rather than mortality from all causes was used as the outcome measure. We therefore conclude that the health impact of smoking is similar in each socio-economic group. The relative health improvement consequent on smoking cessation is thus similar in different socio-economic groups.

Elimination of instrument-driven reflex manual differential leukocyte counts. Optimization of manual blood smear review criteria in a high-volume automated hematology laboratory.

Automated peripheral blood leukocyte differential counts (LDCs) are widely accepted in routine practice. However, many laboratories still reflexively perform manual LDCs based solely on abnormal automated results or instrument "flags," before any manual triage step. We describe our transition to a procedure that uses manual methods to validate, rather than to replace, automated LDCs (an approach recommended early in the development of automated methods, but still not used in many clinical laboratories). Manual microscopic scans were performed in lieu of manual LDCs. Each scan that revealed cell types not quantifiable by the instrument triggered a manual LDC. However, if the manual scan simply confirmed the cell types seen on automated LDC, then the automated result was released, even if clinically significant quantitative abnormalities were present. This policy reduced manual LDCs by more than 70% and was validated by a manual retrospective audit. Patient care and laboratory operations can be optimized by using manual microscopic examination as a validation procedure rather than as a reflexive substitute for automated methods. There is no clinical rationale for reflex performance of manual LDCs based solely on instrument warnings.

Are manual workers at higher risk of death than non-manual employees when living in Swedish municipalities with higher income inequality?

OBJECTIVES: To test the hypothesis that manual workers are at higher risk of death than are non-manual employees when living in municipalities with higher income inequality. DESIGN: Hierarchical regression was used for the analysis were individuals were nested within municipalities according to the 1990 Swedish census. The outcome was all-cause mortality 1992-1998. The income measure at the individual level was disposable family income weighted against composition of family; the income inequality measure used at the municipality level was the Gini coefficient. PARTICIPANTS: The study population consisted of 1 578 186 people aged 40-64 years in the 1990 Swedish census, who were being reported as unskilled or skilled manual workers, lower-, intermediate-, or high-level non-manual employees. RESULTS: There was no significant association between income inequality at the municipality level and risk of death, but an expected gradient with unskilled manual workers having the highest risk and high-level non-manual employees having the lowest. However, in the interaction models the relative risk (RR) of death for high-level non-manual employees was decreasing with increasing income inequality (RR = 0.77; 95% CI, 0.63-0.93), whereas the corresponding risk for unskilled manual workers increased with increasing income inequality (RR = 1.24; 95% CI, 1.06-1.46). The RRs for skilled manual, low- and medium- level non-manual employees were not significant. Controlling for income at the individual level did not substantially alter these findings, neither did potential confounders at the municipality level. CONCLUSIONS: The findings suggest that there could be a differential impact from income inequality on risk of death, dependent on individuals' social position.

Manual fixation versus locking during upper cervical segmental mobilization. Part 1: an in vitro three-dimensional arthrokinematic analysis of manual flexion-extension mobilization of the atlanto-occipital joint.

BACKGROUND: Segmental manual spinal mobilization techniques are used to restrict the effects of interventions to one spinal segment. It is, however, not known whether it is possible to generate such a localization of effects. Segmental motion in the cervical spine was previously studied by applying pure moments of force on cadaver specimens. So far, no studies have been performed on the segmental three-dimensional (3D)-kinematic aspects of cervical manual flexion-extension mobilization. METHODS: 3D-aspects of manual flexion-extension motion in the atlanto-occipital and atlanto-axial segments were analysed in vitro using an electromagnetic tracking device. Segmental bony reference points were registered using a 3D-digitizing stylus to define bone-embedded coordinate frames. Six spinal specimens--five embalmed and one fresh--were analysed in this study. Segmental motions were analysed in the atlanto-occipital and the atlanto-axial joints during manual mobilization through the full range of flexion-extension mobility. The 3D-kinematic analysis of two different segmental mobilization techniques--manual fixation of C1 versus locking of the inferior cervical spine--is presented. RESULTS: A significant reduction (P<0.05) of the associated axial rotation and lateral bending motions was observed during the manual fixation technique without influencing the main motion component of flexion-extension. The locking technique did not significantly influence the movements on the mobilized atlanto-occipital segment, but reduced all movement components in the atlanto-axial joint. INTERPRETATIONS: The results suggest that, for manual segmental flexion-extension mobilization of the upper cervical spine, manual fixation or locking might be chosen in different situations according to the desired effects.

Becoming a manual occupation? The construction of a therapy manual for use with language impaired children in mainstream primary schools.

BACKGROUND: The construction of therapy protocols for a large-scale randomized controlled trial comparing speech and language therapists and assistants, and group and individual therapy approaches for children aged 6-11 in mainstream schools is outlined. AIMS: The aim was to outline the decision-making processes that led to the construction of the research therapy manual, and to give a preliminary report on compliance with the manual. METHODS & PROCEDURES: A search of the research and professional literature and of published therapy materials was conducted to locate usable examples of effective language therapy for primary school children. Results were collated into a manual of therapy principles and activities to structure research intervention. The use of the manual with children (n=30) receiving individual or group direct therapy from a speech and language therapist in the first phase of intervention was audited. OUTCOMES & RESULTS: Very few high-level research studies were found, but the professional literature gave added information. Therapies for comprehension monitoring, vocabulary development, later grammar and narrative were adapted for the research intervention, and procedures compiled into a manual to guide research speech and language therapists and assistants. The audit of direct therapy suggested that the manual was useable, providing a suitable range of activities and materials for therapy intervention. Its use helped to record the therapy offered to research children, and formed a sound basis for discussion amongst speech and language therapists and between speech and language therapist/assistant pairs. CONCLUSIONS: The construction and use of a therapy manual allowed the provision of replicable therapy within the research project whilst maintaining flexibility.

Manual fixation versus locking during upper cervical segmental mobilization. Part 2: an in vitro three-dimensional arthrokinematic analysis of manual axial rotation and lateral bending mobilization of the atlanto-axial joint.

BACKGROUND: Three-dimensional kinematic aspects of coupled motion during manual cervical mobilization have not previously been studied. Using an in vitro 3D-motion analysis method, the kinematic effects of two different segmental techniques for axial rotation and lateral bending mobilization of the upper cervical spine were investigated as a second part of the study (in part one, kinematic effects of flexion-extension mobilization have been investigated). METHODS: Axial rotation and lateral bending mobilization of the atlanto-occipital and atlanto-axial segments were analysed in vitro using an electromagnetic tracking device. Local reference frames were defined based on bony reference points that were registered using a 3D-digitizing stylus. Five embalmed and one fresh specimen were analysed. Segmental motion was registered simultaneously in the atlanto-occipital and the atlanto-axial joints during manual mobilization through the full range of axial rotation and lateral bending mobility. The 3D-kinematic aspects during regional mobilization were compared with those during segmental mobilization with manual fixation and during segmental mobilization using a locking technique. RESULTS: During both segmental axial rotation techniques of the atlanto-axial joint, a significant reduction of the coupled lateral bending and flexion-extension motion was observed. The locking technique also induced an increase in the main axial rotation component. During lateral bending mobilization of the atlanto-axial joint, the manual fixation technique reduced the effect on the coupled flexion-extension component significantly. INTERPRETATIONS: These results suggest that for manual segmental axial rotation and lateral bending mobilization of the upper cervical spine segmental manual fixation or locking may be preferred in different situations depending on the desired effects. This study brings additional information to the data provided by part 1 of this study on the 3D-arthrokinematic effects of flexion-extension mobilization.

Variance in manual treatment of nonspecific low back pain between orthomanual physicians, manual therapists, and chiropractors.

OBJECTIVE: The aim of the study was to identify differences in the diagnosis and treatment of nonspecific low back pain among 3 professional groups in the Netherlands: orthomanual physicians, manual therapists, and chiropractors. METHODS: Information was obtained from training materials from professional groups, literature searches, and observation of selected practitioners at work. RESULTS: In The Netherlands, there are differences in education between the 3 professional groups. The focus of orthomanual medicine is on abnormal positions of components of the skeleton and symmetry in the spine. Manual therapy focuses on functional disorders of the musculoskeletal system. Chiropractic focuses on the musculoskeletal and nervous systems in relation to patients' health in general. Orthomanual medicine considers inspection and palpation the most important diagnostic tools. Manual therapists and chiropractors additionally perform tests to determine functional disorders and manual therapists evaluate psychosocial influences. Chiropractors take radiographs if necessary. Orthomanual physicians apply mobilization techniques using fixed protocols. Manual therapists and chiropractors use various manipulation and mobilization techniques and their manipulation techniques differ in amplitude and velocity. CONCLUSIONS: Diagnostic techniques and treatment methods of the 3 professional groups differ considerably. For more accurate reporting of the efficacy of manipulative and mobilizing therapies, the characteristics of treatments should be described in more detail when reported in studies such as randomized clinical trials.

Policy and procedure manual: keeping a high quality manual.

Policy and procedure manuals are now commonly used in hospitals. The policy and procedure manual provides critical care nurses with a wealth of information. Policies are developed to guide the staff to perform nursing care adequately. Together policies and the corresponding procedures let critical care nurses know how to proceed to meet the organisation and the unit goals. As critical care expands the number of policies increases, which may make it more difficult to find a specific policy quickly. Critical care nurses need to look at other solutions for communicating some necessary pieces of information and check to make sure that policy is stated briefly, to the point and logical. It is also necessary to check to see if the information included in the manual is policy and associated procedures. If it is drug information, equipment usage, standards of care, or patient/family teaching material it could be incorporated in a different format or separate manual. As care givers nurses must monitor policies and procedures that are written and make sure they are simple to read, logically written, and easy to find.

The technical manual and the diagnostic manual for the basic radiological system.

An Advisory Group for the World Health Organization has devised a technique manual for use with the Basic Radiological System (BRS). This provides a step-by-step illustration for all the techniques which are likely to be required in rural or small hospitals anywhere. The manual can be modified to match the BRS units produced by different manufacturers. The cooperation of the local trained radiographers will be necessary at the time of installation. A similar manual has been produced for hand-processing using a time-temperature relationship. A diagnostic interpretation manual has been devised to match the BRS projections. This will aid the doctor who has to interpret the films without a radiologist.

Resolving ASCUS without recourse to HPV testing: manual reprocessing of residual automated liquid-based cytology (ALBC) material using manual liquid-based cytology (MLBC).

We show that residual cell material from ThinPrep PapTest (Cytyc Corporation, Boxborough, MA) atypical squamous-cells of undetermined significance (ASCUS) cases may be manually reprocessed to triage women into actionable diagnostic categories (HSIL, LSIL, and Negative). Material remaining from each of 358 ThinPrep ASCUS cases was manually reprocessed as two slides, labeled "A" and "B." Interobserver agreement between case contributors (CCs) and three sequential reviewers (SRs) was analyzed with 186 cases (Study 1), and diagnostic reproducibility between SRs was examined with an additional 172 cases (Study 2). In Study 1, CCs classified 33% of cases as LSIL or greater, SRs classified 60% as LSIL or greater, and there was 58% diagnostic agreement between CCs and SRs. No "Negative" case assignment by one group afforded an "HSIL" assignment by the complementary group. In Study 2, there was 95% agreement between SRs A slide and B slide diagnoses with 54% of A slides and 55% of B slides classified as LISL or greater. Again, no "Negative" case assignment to one slide afforded an "HSIL" assignment to the complementary slide. Overall, 12.6% of the 358 cases showed HSIL, and all HSILs by one observer group were ASCUS or greater by the complementary observer group. Using manual reprocessing beyond the 21-day specimen outdate for HPV testing by the Hybrid Capture II High Risk HPV test (HR-HCII; Digene Corporation, Beltsville, MD), many ThinPrep ASCUS cases were reclassified as LSIL or HSIL. The 12.6% HSIL proportion of this study approximated the 11.5% CIN 2 or greater proportion of the ALTS ASCUS arm. Similar to ALTS, manual liquid-based cytology (MLBC) would have referred nearly 60% of women to colposcopy for a definitive diagnosis of HSIL or LSIL without resorting to HPV testing. These data demonstrate that many cases of automated liquid-based cytology (ALBC)-diagnosed ASCUS represent unrecognized SIL, which is present in the ALBC specimen vial at the time the ASCUS diagnosis is rendered.

Manual laterality in nonhuman primates: a distinction between handedness and manual specialization.

This article examines individual and group manual lateralization in nonhuman primates as a function of task's demands. It is suggested to distinguish low- from high-level manual activities with respect to the novelty variable and to the spatiotemporal scale of the movements. This review shows that low-level tasks lead to (a) symmetrical distributions of hand biases for the group and (b) manual preferences that are not indicative of the specialization of the contralateral hemisphere. In contrast, behaviors expressed in high-level tasks (a) show asymmetrical distribution of hand biases for the group and (b) seem to be related to a specialization of the contralateral hemisphere. Two types of lateralization, handedness and manual specialization, correspond to the 2 levels of tasks that are distinguished.

Comparison of the Rapid Entire Body Assessment and the New Zealand Manual Handling 'Hazard Control Record', for assessment of manual handling hazards in the supermarket industry.

This is a case study comparing the use of two different assessment tools (Rapid Entire Body Assessment versus New Zealand Manual Handling Hazard Control Record) to assess, plan and implement changes in manual handling practices in the supermarket industry. Existing manual handling practices being used within these supermarkets were assessed using each of these tools. The most hazardous tasks were revised to improve work methods and reviewed again using both tools, to determine the usefulness and effectiveness of these tools. The process generated considerable discussion regarding the benefits and drawbacks of each tool. The usefulness of each tool appears dependant on the reason for assessment and the anticipated outcome. REBA may be more useful if specific ergonomic or biomechanical changes are being implemented to decrease risk of work-related injury (particularly if an objective numeric score is required for re-assessment following modifications, to determine their effectiveness). The New Zealand Code of Practice for Manual Handling 'Hazard Control Record' Risk Score analysis process lacks specificity and objectivity, however it is less reductionistic and takes into account many factors other than biomechanics and ergonomics. It directs the user toward implementing controls, which are thorough, multi-factorial and useful to control hazards relating to several other areas, including task, load, environment, people and management factors.

Comparison of automated and manual determination of HER2 status in breast cancer for diagnostic use: a comparative methodological study using the Ventana BenchMark automated staining system and manual tests.

This study was performed to test the validity of manual and automated HER2 tests in one hundred routinely formalin-fixed and paraffin-embedded diagnostic breast carcinoma tissues. Immunohistochemical (IHC) and fluorescence in situ hybridization (FISH) assays for HER2 were separately carried out in two institutes of pathology specialised in diagnostics of breast diseases. Manual immunostaining was performed by the Dako-HercepTest. Automated IHC and FISH were carried out in the Ventana BenchMark platform by using the Pathway-CB11 antibody and the INFORM(R) HER2 probe, respectively. Positivity rates varied between HercepTest (26%), automated CB11 IHC (23%) and automated FISH (22%). Overall concordance between positive (2+, 3+) and negative (0; 1+) results of manual and automated IHC was 97%, between automated FISH and IHC 92%, and between automated FISH and HercepTest 89%. The frequency of 2+ IHC scores was 13% using the BenchMark and 14% with the HercepTest; 6/12 and 8/14 of the respective cases were not amplified by FISH. Automated FISH was not interpretable in 11 of 100 specimens. In the 89 informative cases, automated IHC resulted in increased specificity (92% vs. 88%), increased positive predictive value (73% vs. 64%) and increased efficiency (92% vs. 89%). We conclude that automation improves the accuracy of HER2 detection in diagnostic breast carcinoma tissues and provides a new approach for the global standardization of clinical HER2 tests.

Analysis of multiple activity manual materials handling tasks using A Guide to Manual Materials Handling.

Manual handling of materials continues to be a hazardous activity, leading to a very significant number of severe overexertion injuries. Designing jobs that are within the physical capabilities of workers is one approach ergonomists have adopted to redress this problem. As a result, several job design procedures have been developed over the years. However, these procedures are limited to designing or evaluating only pure lifting jobs or only the lifting aspect of a materials handling job. This paper describes a general procedure that may be used to design or analyse materials handling jobs that involve several different kinds of activities (e.g. lifting, lowering, carrying, pushing, etc). The job design/analysis procedure utilizes an elemental approach (breaking the job into elements) and relies on databases provided in A Guide to Manual Materials Handling to compute associated risk factors. The use of the procedure is demonstrated with the help of two case studies.

[Reliability of manual medical examination techniques of the cervical spine. Study of quality assurance in manual diagnosis].

OBJECTIVE: Chiropractic techniques are of particular importance for the examination of the cervical spine. The aim of this study was to assess interexaminer reliability of examination techniques of the cervical spine in subjects with and without musculoskeletal distortions of the neck. The interrater method was used with five independent examiners. METHOD: Twenty patients suffering from neck diseases and 20 asymptomatic subjects of similar age and gender were randomized and assessed by five examiners blind to patient histories. Statistical analysis was carried out using multiple logistic regression and the calculation of kappa. RESULTS: Compared to asymptomatic subjects, patients experienced pain significantly often when pressure was applied to the cervical zygapophysial joints and the superficial neck muscles (p < or = 0.05 and p < or = 0.01). In addition, segmental function tests induced kinesialgia significantly more often in patients than in asymptomatic subjects (p < or = 0.05 and p < or = 0.01). A significant relationship was not found between the patient's health status and the findings from muscle palpation and functional examination of the motion segments. The assessment of agreement within examiners beyond chance had to be calculated, aside from for few exceptions, little to moderate (0.2 < kappa < or = 0.6). CONCLUSIONS: Chiropractic techniques are an essential part of every examination of the cervical spine. The clinical impact has not been scientifically established until up to now. Based on our findings and literature, we conclude that interexaminer reliability of manual diagnosis in the examination of the cervical spine should be improved by standardizing the examination process and setting guidelines for documentation and evaluation criteria. Controlled and frequently repeated training sessions also contribute to the reproducibility of findings from manual examinations.
