Background: Interferential therapy (IFT) is applied to intersect in the painful area but no confirmed effect with this method. Experimentally, the highest voltage of IFT is induced outside the intersection of the two currents. Placing the painful area outside the intersection point (external application) would reveal a better effect.

Objectives: To examine the effect of external application in pain compared to traditional method.

Design: A double-blind placebo-controlled clinical investigation.

Setting: A public hospital.

Participants: 168 LBP subjects.

Interventions: Assignment: (1) external IFT, (2) placebo external IFT, (3) traditional IFT and (4) placebo traditional IFT. Groups 1 and 3 received 20 min of IFT at 100 Hz and groups 2 and 4 received sham IFT.

Main outcome measures: Before and after IFT session, pain severity (VAS), pressure threshold (PPT), pain distribution and ROM were assessed.

Results: IFT changed all outcomes similarly. VAS and ROM improved statistically, P < 0.03. A trend of better VAS reduced with active IFTs.

Conclusions: No therapeutic difference between the two methods.  相似文献

Background:

The utility of a dedicated clinical test is dependent on the diagnostic accuracy values and the quality of the study in which the test was examined. Scales allow a summative scoring of bias within a study. At present, there are no scales advocated to measure the bias of diagnostic accuracy studies.

Objective:

The objective of this study was to create a new diagnostic accuracy quality scale (DAQS) that provides a quantitative summary of the methodological quality of studies evaluating clinical tests and measures.

Design:

The study used a four-round Delphi survey designed to create, revise, and develop consensus for a quality scale.

Methods:

The four-round Delphi involved a work team and a respondent group of experts. An initial round among the work team created a working document, which was then modified and revised, with opportunities to create new items threaded in the second round. Rounds III and IV involved voting on the importance of each of the proposed items and consensus development from the respondent group. Consensus for the selection of an item required a 75% approval for the importance of that item.

Results:

Sixteen individuals with a variety of research/professional backgrounds made up the respondent group. Modification and revision of the initial work team instrument created a scale with 21 items that reflected potential areas of methodological bias.

Limitations:

The new scale needs validation through weighted assessment. In addition, there was a large proportion of physical therapist/researchers on the work team and the respondent group.

Conclusions:

Systematic reviews allow summation of evidence for clinical tests and scales are essential to critique the quality of the articles included in the review. The DAQS may serve this role for diagnostic accuracy studies.  相似文献

Objectives:

Pain Pattern Classification (PPC) and Directional Preference (DP) have been shown to be predictive of health care outcomes and serve to guide orthopedic clinical decision making. We conducted a prospective, observational cohort study to verify the association between PPC, DP, and clinical outcomes.

Methods:

Clinical outcome measures including pain intensity and disability were completed at first examination and follow-up by 335 patients. A Pearson’s chi-squared test was used to determine differences in prevalence rates for the categorical variables, and two-sample t-tests were used to determine differences in rates for the continuous variables. A Tukey’s range test was used to determine differences in follow-up pain intensity and disability for neck pain dual-classification schemes.

Results:

The prevalence of DP was 82.4%. The prevalence of CEN, Non-CEN, and Non-Classifiable (NC) was 15.2%, 42.1%, and 25.1%, respectively. The prevalence of DP was lowest for patients with sub-acute symptoms and who were <45 years old. Patients classified as DP CEN had, on average 2.62 NDI units less than patients classified as Non-DP. Patients classified as DP CEN had, on average, 0.90 pain intensity units less than patients classified as Non-DP at follow-up. Patients who demonstrated DP CEN did not have clinically significant lower pain intensity or disability at follow-up than patients who demonstrated Non-DP.

Discussion:

The results of this investigation need to be interpreted with caution with respect to the study design and it’s subsequent strengths and limitations.

Background:

Yoga is a popular complementary and alternative medicine (CAM) therapy among people with rheumatoid arthritis (RA), perceived as offering self-management options for physical and psychosocial symptoms associated with RA.

Objectives:

The primary aims of the current pilot study are (1) to assess the feasibility and safety of a relaxation-focused yoga intervention tailored for people with RA and (2) to estimate the effect of yoga on RA-related pain, sleep quality, functional disability, disease activity, quality of life, anxiety, depression, and fatigue.

Method:

Twenty-eight participants with at least minimum levels of RA-related pain and sleep disturbance will be recruited from a local public hospital database. Participants meeting inclusion criteria will be randomized into either a yoga group (receiving an 8-week program of once-weekly 75-minute relaxation-based yoga classes and thrice-weekly home practice), or a usual care control group. Outcomes will be assessed at baseline, 9, and 12 weeks. Feasibility is operationalized as acceptability (recruitment, adherence, participant retention, and participant satisfaction) and safety of the yoga intervention. Effect sizes for changes in pain, sleep quality, functional disability, disease activity, quality of life, mental health, and fatigue will be estimated.

Discussion:

Results of this pilot study will provide empirical data to determine if a larger, statistically powered main trial is feasible and safe in a national RA population. Additionally, participant feedback will provide information regarding further adaption and tailoring of the study protocol to a clinical RA population.

Introduction: Psoriasis, a chronic immune-mediated skin disorder is associated with significant physical, psychological, and quality of life impairments. Along with well-documented genetic and environmental factors, immunological factors also contribute to the pathogenesis of psoriasis. Among the immunological factors, CD6 – dependent T-cell proliferation to form Th1 and Th17 cells play a major role in the pathogenesis of psoriasis. Itolizumab is the first humanized IgG1 monoclonal antibody, which selectively targets CD6.

Areas covered: The current article presents the pharmacology of itolizumab and provides a review of the currently available data on the efficacy and safety of itolizumab for management of moderate to severe plaque psoriasis.

Expert opinion: The use of biologics to attenuate the immune-mediated pathological events in psoriasis is a relatively well-established clinical practice. However, the safety and efficacy of biologics continues to be an unsettled topic of ongoing research. While available data seems to suggest that itolizumab may be a safer option, additional studies with higher sample sizes and active comparators are needed before definitive conclusions can be drawn on the place of itolizumab in the management of psoriasis.  相似文献

Context: Intentional overdose is a leading method of self-harm and suicide, and repeat attempts strongly predict eventual death by suicide.

Objectives: To determine the risk of recurrence after a first intentional overdose. Secondary objectives included characterization of the temporal course and potential predictors of repeat overdose, a strong risk factor for death from suicide.

Methods: Design: Population-based cohort study.

Setting: Ontario, Canada, from 1 April 2002 to 31 March 2013.

Participants: All Ontario residents presenting to an emergency department after a first intentional overdose.

Main outcome measures: The incidence and timing of recurrent overdose.

Results: We followed 81,675 patients discharged from hospital after a first intentional overdose. Overall, 13,903 (17.0%) returned with a repeat overdose after a median interval of 288 (inter-quartile range: 62 to 834) days. Of these, 4493 (5.5%) had multiple repeat episodes. Factors associated with repeat self-poisoning included psychiatric care in the preceding year (adjusted hazard ratio [aHR] 1.55; 95% confidence interval [CI] 1.50 to 1.61), alcohol dependence (aHR 1.41; 95% CI 1.35 to 1.46) and documented depression (aHR 1.39; 95% CI 1.34 to 1.44). Female sex, rural residence, lower socioeconomic status, ingestion of psychoactive drugs and younger age were also weakly associated with repeat overdose.

Discussion: Hospital presentation for repetition of intentional overdose is common, with recurrent episodes often far removed from the first. While several factors predict overdose repetition, none is particularly strong.

Conclusion: Secondary prevention initiatives should be implemented for all individuals who present to the emergency department and survive intentional overdose.  相似文献

Objective: Reverse triage means that patients who are not considered to be in need of medical services are not placed on the doctor’s list in an emergency department (ED) but are sent, after face-to-face evaluation by a triage nurse, to a more appropriate health care unit. It is not known how an abrupt application of such reverse triage in a combined primary care ED alters the demand for doctors’ services in collaborative parts of the health care system.

Design: An observational study.

Setting: Register-based retrospective quasi-experimental longitudinal follow-up study based on a before–after setting in a Finnish city.

Subjects: Patients who consulted different doctors in a local health care unit.

Main outcome measures: Numbers of monthly visits to different doctor groups in public and private primary care, and numbers of monthly referrals to secondary care ED from different sources of primary care were recorded before and after abrupt implementation of the reverse triage.

Results: The beginning of reverse triage decreased the number of patient visits to a primary ED doctor without increasing mortality. Simultaneously, there was an increase in doctor visits in the adjacent secondary care ED and local private sector. The number of patients who came to secondary care ED without a referral or with a referral from the private sector increased.

Conclusions: The data suggested that the reverse triage causes redistribution of the use of doctors’ services rather than a true decrease in the use of these services.  相似文献

Objective: To develop quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections, tailored to the Danish general practice setting.

Design: A RAND/UCLA Appropriateness Method was used.

Setting: General practice.

Subjects: A panel of nine experts, mainly general practitioners, was asked to rate the relevance of 64 quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections based on guidelines. Subsequently, a face-to-face meeting was held to resolve misinterpretations and to achieve consensus.

Main outcome measures: The experts were asked to rate the indicators on a nine-point Likert scale. Consensus of appropriateness for a quality indicator was reached if the overall panel median rating was 7–9 with agreement.

Results: A total of 50 of the 64 proposed quality indicators attained consensus. Consensus was achieved for 12 indicators focusing on the diagnostic process and 19 indicators focusing on the decision about antibiotic treatment and choice of antibiotics, respectively.

Conclusion: These newly developed quality indicators may be used to strengthen Danish general practitioners’ focus on their management of patients with acute respiratory tract infections and to identify where there is a need for future quality improvements.  相似文献

Objective: The Coordination reform was implemented in Norway from 2012, aiming at seamless patient trajectories. All municipalities are required to establish emergency care beds (MEBs) to avoid unnecessary hospital admissions. We aimed to examine occupancy rate, patient characteristics, diagnoses and discharge level of municipal care in a small MEB unit.

Design: Cross-sectional, observational study.

Setting: A two-bed emergency care unit.

Subjects: All patients admitted to the unit during one year.

Main outcome measures: Patients’ age and gender, comorbidity, main diagnoses and municipal care level on admission and discharge, diagnostic and therapeutic initiatives, occupancy rate.

Results: Sixty admissions were registered, with total bed occupancy 194 days, and an occupancy rate of 0.27. The patients (median age 83 years, 57% women) had mostly infections, musculoskeletal symptoms or undefined conditions. Some 48% of the stays exceeded three days and 43% of the patients were subsequently transferred to nursing homes or hospitals.

Conclusion: Occupancy rate was low. Patient selection was not according to national standards, and stays were longer. Many patients were transferred to nursing homes, indicating that the unit was an intermediate pathway or a short cut to institutional care. It is unclear whether the unit avoided hospital admissions.  相似文献

Objective: We describe the drug-related problems (DRPs) identified during medication reviews (MRs) and the changes in drug utilization after MRs at nursing homes in Oslo, Norway. We explored predictors for the observed changes.

Design: Observational before-after study.

Setting: Forty-one nursing homes.

Intervention: MRs performed by multidisciplinary teams during November 2011 to February 2014.

Subjects: In all, 2465 long-term care patients.

Main outcome measures: DRPs identified by explicit criteria (STOPP/START and NORGEP) and drug–drug interaction database; interventions to resolve DRPs; drug use changes after MR.

Results: A total of 6158 DRPs were identified, an average of 2.6 DRPs/patient, 2.0 for regular and 0.6 for pro re nata (prn) drugs. Of these patients, 17.3% had no DRPs. The remaining 82.7% of the patients had on average 3.0 DRPs/patient. Use of unnecessary drugs (43.5%), excess dosing (12.5%) and lack of monitoring of the drug use (11%) were the most frequent DRPs. Opioids and psychotropic drugs were involved in 34.4% of all DRPs. The mean number of drugs decreased after the MR from 6.8 to 6.3 for regular drugs and from 3.0 to 2.6 for prn drugs. Patients with DRPs experienced a decrease of 1.1 drugs after MR (0.5 for regular and 0.6 for prn drugs). The reduction was most pronounced for the regular use of antipsychotics, antidepressants, hypnotics/sedatives, diuretics, antithrombotic agents, antacid drugs; and for prn use of anxiolytics, opioids, hypnotics/sedatives, metoclopramide and NSAIDs.

Conclusion: The medication review resulted in less drug use, especially opioids and psychotropic drugs.  相似文献

Introduction: Most systemic therapies have not been systematically investigated in moderate to severe childhood plaque psoriasis. Evidence on the efficacy and safety of systemic treatments is limited and therapeutic guidelines are lacking. Recently adalimumab, a fully human monoclonal antibody that binds tumor necrosis factor (TNF)- alpha, was investigated in childhood psoriasis. Adalimumab is licensed for many inflammatory conditions including chronic plaque psoriasis in adults.

Areas covered: A randomized phase III study published provided favourable efficacy and safety data of adalimumab in childhood psoriasis. The active comparator was methotrexate. After 16 weeks of treatment, a PASI 75 score was achieved in 58% of patients within the adalimumab 0.8 mg/kg group compared with 32% of patients within the methotrexate group. Safety data gave no evidence of drug-related serious adverse events and no organ toxicity. This is the first randomised controlled study of either adalimumab or methotrexate in children and adolescents with psoriasis.

Expert opinion: The aforementioned trial was the first to provide clinical data on adalimumab’s efficacy and safety in the short term when treating children and adolescents with psoriasis. Through the use of an active comparator, this study has opened the way for the future assessment of systemic therapies in children and adolescent with this condition.  相似文献

Background: The primary aim when providing advice to patients on fitness to drive is the safety of the patient and the general public. Within the current Australian guidelines there is little specific information in regards to providing advice to palliative care patients about driving.

Method: Online survey.

Objective: To investigate the current practice of doctors and the advice provided to palliative care patients about their fitness to drive.

Discussion: When advising a patient with a medical condition that could affect fitness to drive, most respondents were not in consensus with the driving guidelines with only 38% following the recommended procedure. It found some disparity in the advice provided and differences to the Australian driving guidelines.  相似文献

Background: As the population of older adults continues to increase, there will be an increase in the number of older patients requiring pain and symptom management in the setting of advanced, serious illness.

Objectives: To review age-related changes in pharmacokinetics and pharmacodynamics, and to put these changes in the context of providing palliative care to geriatric patients.

Method: Review of literature relevant to age-related changes in physiology, pharmacokinetics, and pharmacodynamics; and the practice of palliative care for geriatric patients.

Results: Multiple age related changes occur which affect the choice and dosing of medications, including those used for pain and symptom management.

Conclusion: The safe and effective management of symptoms in advanced illness for older adults depends on having a clear understanding of physical and metabolic changes and their impact of selection of drug therapy.  相似文献

Background:

The effective management of lateral canal benign paroxysmal positional vertigo (LC-BPPV) is dependent upon the accurate identification of the affected ear. The supine roll test is the gold standard for diagnosing LC-BPPV. However, in some cases, the elicited nystagmus has a similar intensity when the head is rolled to the right or to the left.

Objectives:

The purpose of this systematic review was to determine the effectiveness of accessory diagnostic procedures, used in conjunction with the supine roll test, at accurately identifying the affected ear in individuals with LC-BPPV.

Methods:

The following databases were searched: (1) CINAHL Plus with Full Text, (2) ProQuest Medical Library, and (3) MEDLINE. The following search terms were used: (1) ‘lateral canal’ OR ‘horizontal canal’ AND (2) ‘positional vertigo’ OR ‘positioning vertigo’ OR ‘positional nystagmus’ OR ‘positioning nystagmus’. Evidence level was examined with the Oxford Centre for Evidence-Based Medicine 2011 levels of evidence method, and methodological rigour was examined with the QUADAS method.

Results:

A database search originally identified 1348 records, and nine studies were ultimately included in the qualitative synthesis. This systematic review revealed four index tests that, when used in conjunction with the supine roll test, were able to accurately identify the affected ear in a majority of individuals with LC-BPPV.

Conclusions:

The pseudo-spontaneous test was found to be slightly superior to the other three index tests in terms of eliciting nystagmus during its administration and identifying the same affected ear as the supine roll test.  相似文献

Background: Self-rated health (SRH) measures one’s current general health and is a widely used health indicator. Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships are suspected to influence SRH, but studies in primary health care settings are sparse.

Objective: To examine the associations between patients’ self-rated health and their sleep problems, somatic health complaints, and unmet needs in interpersonal relationships.

Design: We collected data via questionnaires for this cross-sectional study from general practice.

Setting: Primary health care in Norway.

Subjects: 1302 consecutive patients participated.

Main outcome measures: The questionnaire included a single question about SRH, the Bergen Insomnia Scale (BIS), five questions on somatic health complaints, and three questions from the Basic Psychological Needs Scale (BPNS) pertaining to the relationships domain. We analyzed our data using ordinal logistic regression models.

Results: Our response rate was 74%. The prevalence of fair/poor SRH was 26%, with no gender differences. We revealed a significant association between increasing age and reduced SRH. The study showed that sleep problems and somatic health complaints were strongly associated with SRH, and unmet needs in relationships were also significantly and independently associated with reduced SRH in a full model analysis.

Conclusion: Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships were all associated with reduced SRH. These factors are all modifiable and could be managed both within and outside a primary care setting in order to improve SRH.

  • Key Points
  • There was a high prevalence of reduced SRH in clinical general practice

  • Sleep problems, somatic health complaints, and unmet needs in interpersonal relationships were all associated with reduced SRH

  • These predictors are all modifiable with a potential to improve SRH

Objective:

to review and update the evidence for different forms of manual therapy (MT) for patients with different stages of non-specific low back pain (LBP).

Data sources:

MEDLINE, Cochrane-Register-of-Controlled-Trials, PEDro, EMBASE.

Method:

A systematic review of MT with a literature search covering the period of January 2000 to April 2013 was conducted by two independent reviewers according to Cochrane and PRISMA guidelines. A total of 360 studies were evaluated using qualitative criteria. Two stages of LBP were categorized; combined acute–subacute and chronic. Further sub-classification was made according to MT intervention: MT1 (manipulation); MT2 (mobilization and soft-tissue-techniques); and MT3 (MT1 combined with MT2). In each sub-category, MT could be combined or not with exercise or usual medical care (UMC). Consequently, quantitative evaluation criteria were applied to 56 eligible randomized controlled trials (RCTs), and hence 23 low-risk of bias RCTs were identified for review. Only studies providing new updated information (11/23 RCTs) are presented here.

Results:

Acute–subacute LBP: STRONG-evidence in favour of MT1 when compared to sham for pain, function and health improvements in the short-term (1–3 months). MODERATE-evidence to support MT1 and MT3 combined with UMC in comparison to UMC alone for pain, function and health improvements in the short-term.

Chronic LBP:

MODERATE to STRONG-evidence in favour of MT1 in comparison to sham for pain, function and overall-health in the short-term. MODERATE-evidence in favour of MT3 combined with exercise or UMC in comparison to exercise and back-school was established for pain, function and quality-of-life in the short and long-term. LIMITED-evidence in favour of MT2 combined with exercise and UMC in comparison to UMC alone for pain and function from short to long-term. LIMITED-evidence of no effect for MT1 with extension-exercise compared to extension-exercise alone for pain in the short to long-term.

Conclusion:

This systematic review updates the evidence for MT with exercise or UMC for different stages of LBP and provides recommendations for future studies.  相似文献

Background:

Many patients present to physical therapy with mechanical neck pain. Cervical and thoracic manipulations are being utilized in treating this impairment, but minimal evidence as to which technique is superior exists in the literature.

Objective:

The purpose of this systematic review is to identify whether cervical or thoracic manipulation is more effective at improving pain, range of motion (ROM), and disability in patients with mechanical neck pain.

Methods:

A comprehensive search of published literature from seven search engines (PubMed, ProQuest, PEDro, CINAHL, Healthsource, Cochrane Library, SPORTDiscus) yielded 13 studies that examined the effectiveness of either cervical manipulations, thoracic manipulations, or cervical and thoracic manipulations to relieve the effects of mechanical neck pain. Eleven of the studies included were randomized controlled trials (RCTs), while two were secondary analyses of RCTs. Each study was assessed using the PEDro scale and found to be of fair to high research quality.

Results:

The studies included in this systematic review produced both positive clinical and statistical differences in pain, disability, and ROM following manipulations of the cervical or thoracic spine.

Conclusion:

There is limited high-quality research directly comparing the two interventions, so determining whether cervical or thoracic thrust manipulation is superior cannot be concluded from this systematic review alone. However, based on the results found in this review, cervical and thoracic thrust manipulations are equally valuable in relieving pain, disability, and improving ROM for a patient with mechanical neck pain in the short term.  相似文献

Background:

The relationship between deprivation status and health is well documented with less deprived populations experiencing lower rates of morbidity and mortality than those from more deprived groups. The mechanisms that link deprivation to health are multi-factorial and complex. The relationship between deprivation and health remains largely unexplored in physiotherapy management.

Objectives:

To systematically collate, appraise, and summarize primary studies that investigate the relationship between deprivation and treatment outcomes in physiotherapy.

Methods:

A systematic search of electronic databases was performed using a specified strategy. A three-phase screening process was used to identify relevant primary studies. Two independent reviewers selected the articles, rated quality, and extracted data. Meta-analysis was not performed due to diversity of conditions, interventions, and outcome measures used. Qualitative analysis was performed, and levels of evidence were generated using an established framework.

Results:

Three studies met the inclusion criteria; all were deemed of high quality. All three studies found that low socioeconomic status (SES) negatively influenced physiotherapy treatment outcomes.

Conclusion:

There is strong evidence to suggest that low SES negatively affects treatment outcomes in physiotherapy. This is in line with findings from other areas of medicine and allied health. The relationship appears to be complex and multifaceted. Key potential causal mechanisms are identified and explored with reference to existing literature. Further research is required to elucidate this complex relationship and to allow development of strategies that reduce the impact of deprivation on physiotherapy outcomes.  相似文献

Background:

Vibration intervention has recently become a popular modality in professional sport and fitness and has also been suggested to offer potential in augmenting exercises in the rehabilitation field for various neurological conditions.

Objectives:

The main objective of this review was to assess the effects of whole-body vibration (WBV) intervention on body functions, activity limitations, and participation restrictions in people with neurological conditions. The second objective was to assist healthcare professionals in their clinical practice by evaluating the main parameters of WBV intervention that may be of benefit.

Methods:

Electronic databases (EMBASE, Academic Search Complete, AMED, MEDLINE, CINAHL Plus, SPORTDiscus, PEDro, and Cochrane library) were searched. Intervention studies with a comparison group, investigating the effect of WBV intervention on people with neurological conditions, were included. The methodological quality of papers was independently assessed by two raters using the Physiotherapy Evidence Database scale.

Results:

Sixteen randomized controlled trials (RCTs) were included. Only one paper was considered ‘excellent’ methodological quality study (9 out of 10 points). Four studies evaluated changes when WBV was compared to no intervention and two found significant improvements for strength, gait, and balance. Twelve compared WBV to other interventions and only two found significant differences in favour of the WBV group, for strength and gait.

Conclusion:

The cumulative findings for strength, balance, and gait suggest that while groups improve following WBV, this improvement is not consistently greater than either no intervention or a comparison intervention. This suggests insufficient evidence to support the effects of WBV training.  相似文献
