Chest physiotherapy for preventing morbidity in babies being extubated from mechanical ventilation.

BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: To assess the effects of active chest physiotherapy on babies being extubated from mechanical ventilation for neonatal respiratory failure. SEARCH STRATEGY: The standard search strategy for the Neonatal Review Group was used as outlined in the Cochrane Handbook in the Cochrane Library. SELECTION CRITERIA: All trials utilising random or quasi-random patient allocation, in which active chest physiotherapy was compared with non-active techniques (eg positioning and suction alone) or no intervention in the periextubation period. The methodological quality of each trial was assessed by two independent authors. DATA COLLECTION AND ANALYSIS: Data were extracted independently by two authors. The data were analysed from 3 trials. Subgroup analysis was performed on different treatment frequencies. MAIN RESULTS: In this review of 3 small trials, 2 of which were carried out 10 & 20 years ago, no clear benefit of periextubation active chest physiotherapy can be seen. Active chest physiotherapy did not significantly reduce the rate of postextubation lobar collapse (RR 0.69;0.33,1.45), though a reduction in the use of reintubation was shown in the overall analysis (RR 0.24;0.08,0.75). Subgroup analysis of different treatment frequencies showed the same effect with more frequent treatment (1 & 2 hourly) but showed a trend to increased lobar collapse, and no reduction in the use of reintubation, with less frequent treatment (4 hourly). There is insufficient information to assess other important short and long term outcomes, including adverse effects. REVIEWER'S CONCLUSIONS: The results of this review do not allow development of clear guidelines for clinical practice. Caution is required when interpreting the possible positive effects of chest physiotherapy of a reduction in the use of reintubation and the trend for decreased post-extubation atelectasis as the numbers of babies studied are small, the results are not consistent across trials, data on safety are insufficient, and applicability to current practice may be limited.

Randomised trial of a brief physiotherapy intervention compared with usual physiotherapy for neck pain patients: outcomes and patients' preference.

OBJECTIVES: Firstly, to compare the effectiveness of a brief physiotherapy intervention with "usual" physiotherapy for patients with neck pain. Secondly, to evaluate the effect of patients' preferences on outcome. DESIGN: Non-inferiority randomised controlled trial eliciting preferences independently of randomisation. SETTING: Physiotherapy departments in a community setting in Yorkshire and north Lincolnshire. PARTICIPANTS: 268 patients (mean age 48 years) with subacute and chronic neck pain, who were referred by their general practitioner and randomly assigned to a brief physiotherapy intervention (one to three sessions) using cognitive behaviour principles to encourage self management and return to normal function or usual physiotherapy, at the discretion of the physiotherapist concerned. MAIN OUTCOME MEASURES: The Northwick Park neck pain questionnaire (NPQ), a specific measure of functional disability resulting from neck pain. Also, the short form 36 (SF-36) questionnaire, a generic, health related, quality of life measure; and the Tampa scale for kinesophobia, a measure of fear and avoidance of movement. RESULTS: At 12 months, patients allocated to usual physiotherapy had a small but significant improvement in NPQ scores compared with patients in the brief intervention group (mean difference 1.99, 95% confidence interval 0.45 to 3.52; P = 0.01). Although the result shows a significant inferiority of the intervention, the confidence interval shows that the effect could be in the non-inferiority range for the brief intervention (below 1.2 points of NPQ score). Patients who preferred the brief intervention and received this treatment had similar outcomes to patients receiving usual physiotherapy. CONCLUSIONS: Usual physiotherapy may be only marginally better than a brief physiotherapy intervention for neck pain. Patients with a preference for the brief intervention may do at least as well with this approach. Additional training for the physiotherapists in cognitive behaviour techniques might improve this approach further.

Randomized trial of a brief physiotherapy intervention compared with usual physiotherapy for neck pain patients: cost-effectiveness analysis.

OBJECTIVES: To assess the cost-effectiveness of brief physiotherapy intervention versus usual physiotherapy management in patients with neck pain of musculoskeletal origin in the community setting. METHODS: A cost-effectiveness analysis was conducted alongside a multicenter pragmatic randomized controlled clinical trial. Individuals 18 years of age and older with neck pain of more than 2 weeks were recruited from physiotherapy departments with referrals from general practitioners (GPs) in the East Yorkshire and North Lincolnshire regions in the United Kingdom. A total of 139 patients were allocated to the brief intervention, and 129 to the usual physiotherapy. Resource use data were prospectively collected on the number of physiotherapy sessions, hospital stay, specialist, and GP visits. Quality-adjusted life years (QALYs) were estimated using EQ-5D data collected at baseline, 3 and 12 months from the start of the treatment. The economic evaluation was conducted from the U.K. National Health System perspective. RESULTS: On average, brief intervention produced lower costs (pounds--68; 95 percent confidence interval [CI], pounds--103 to pounds--35) and marginally lower QALYs (-0.001; 95 percent CI, -0.030 to 0.028) compared with usual physiotherapy, resulting in an incremental cost per QALY of pounds 68,000 for usual physiotherapy. These results are sensitive to patients' treatment preferences. CONCLUSIONS: Usual physiotherapy may not be good value for money for the average individual in this trial but could be a cost-effective strategy for those who are indifferent toward which treatment they receive.

A randomized clinical trial to compare selective posterior rhizotomy plus physiotherapy with physiotherapy alone in children with spastic diplegic cerebral palsy.

A randomized controlled single-blind trial was performed to compare lumbo-sacral selective posterior rhizotomy (SPR) followed by intensive physiotherapy, with intensive physiotherapy alone in improving motor function in children with spastic diplegic cerebral palsy. Fifteen patients were randomly assigned to each treatment modality. Patients in the SPR group had rhizotomy within 1 month, followed by intensive outpatient physiotherapy for 9 months. Patients assigned to physiotherapy alone had identical intensive physiotherapy. There was a statistically significant and clinically important difference in improvement in motor function in favor of the SPR group, with a mean increase in total Gross Motor Function Measure (GMFM) score of 11.3% at 9 months for the SPR group compared with 5.2% for the physiotherapy-only group (P = 0.007). Significant improvements in spasticity (P < 0.001) and range of movement (P < 0.001) were noted in the SPR group compared to the physiotherapy-only group. The results indicate that the improvement in motor function after SPR is more than can be explained by the associated intensive physiotherapy.

Comparison between primary care physiotherapy education/advice clinics and traditional hospital based physiotherapy treatment: a randomized trial.

BACKGROUND: Studies have shown that patients prefer to received physiotherapy services in the primary care setting, but none has made direct comparisons between hospital and primary care based physiotherapy. AIM: This pragmatic randomized trial set out to compare general-practice-based physiotherapy education and advice clinics with traditional physiotherapy treatment in an acute hospital setting. METHOD: The study involved 130 patients referred to physiotherapy services by 43 general practitioners over a one-year period. Patients were included in the study if they were at work, independent in all activities of daily living and would have routinely been referred to the hospital physiotherapy department for treatment. Patients were randomly allocated to one of two intervention groups: general practice education/advice, or treatment and education/advice at the local hospital. Patients completed a questionnaire prior to their first physiotherapy appointment and again 6 weeks later. RESULTS: A disappointing number of patients failed to attend either the first or subsequent appointments. The post-intervention scores revealed improvements in patients' problems, with the advice group exhibiting a slightly better outcome than the hospital group, as measured by the Nottingham health profile, the anxiety component of the hospital anxiety and depression rating scale, pain and problem size visual analogue scales, and measures of patient satisfaction. Advice group patients also had less attendances than the hospital treatment group. The general practitioners surveyed commented favourably on the advice clinics. CONCLUSIONS: The findings of this study justify the concept of general-practice-based physiotherapy education and advice clinics.

Cost-utility analysis of physiotherapy treatment compared with physiotherapy advice in low back pain.

STUDY DESIGN: Economic evaluation alongside a pragmatic multicenter randomized controlled trial from the National Health Service (NHS) and societal perspective. OBJECTIVE: To perform a cost-utility analysis of routine physiotherapy treatment compared with an assessment session and advice from a physiotherapist for patients with subacute and chronic low back pain. SUMMARY OF BACKGROUND DATA: Lack of evidence for some types of physiotherapy intervention and a paucity of cost-effectiveness data for treatment of low back pain has led to controversy and uncertainty within the medical and allied professions. PATIENTS AND METHODS: A total of 286 patients with low back pain of more than a 6-week duration were randomized to physiotherapy treatment or advice on remaining active from a physiotherapist. Data were collected on back pain-related NHS and patients' costs over a 12-month post randomization period. The primary outcome measure was the Oswestry Disability Index at 12 months, with additional Oswestry Disability Index measures at 2 and 6 months. The EuroQol EQ-5D was used to calculate quality adjusted life years. Cost-effectiveness was expressed as the incremental cost per quality adjusted life year gained. Uncertainty was handled using confidence ellipses for the ratio and cost-effectiveness acceptability curves. RESULTS: The total NHS costs were not significantly different at 179 pounds sterling (221 pounds sterling) for physiotherapy and 159 pounds sterling (260 pounds sterling) for the advice group. However, patients in the physiotherapy group had significantly higher out-of-pocket health care expenditure (40 pounds sterling, 95% confidence interval 9 pounds sterling to 71 pounds sterling). Utility levels improved in both groups from baseline to 12 months, with no significant differences between groups. CONCLUSIONS: The results indicate no significant differences in either NHS costs or effects. However, the significantly higher out-of-pocket expenses incurred by patients receiving routine physiotherapy suggests that advice given by a physiotherapist should be considered as the first-line treatment for patients with this level of back pain disability.

Physiotherapy caseload guidelines: summary of a report prepared for the Canadian Physiotherapy Association.

Physiotherapy caseload standards were developed in 1975 for the purpose of providing an efficient statistical tool for department heads, administrators and government planners in their consideration of staffing and equipping treatment facilities. This paper is a summary of a report prepared by a committee of the Canadian Physiotherapy Association whose task was to evaluate the standards. Analysis of data collected by Statistics Canada via the Canadian Schedule of Unit Values in 1980-81, showed a high correlation between two primary workload indicators--attendances per department paid hour and attendances per physiotherapist paid hours. Using three of the seventeen statistical indicators developed, the committee prepared physiotherapy caseload standards for seven types of hospitals, categorized by size and the proportion of rehabilitation services they offered. The standards were later revised and reissued as guidelines. This report discusses three of the recommended guidelines: number of attendances per physiotherapy department paid hour; number of attendances per physiotherapist paid hour; and weighted units per physiotherapy department paid hour. A copy of the complete report is available from the Canadian Physiotherapy Association.

Chest physiotherapy compared to no chest physiotherapy for cystic fibrosis.

BACKGROUND: Chest physiotherapy is widely used in patients with cystic fibrosis in order to clear mucus from the airways. OBJECTIVES: To determine the effectiveness and acceptability of chest physiotherapy compared to no treatment or spontaneous cough alone to improve mucus clearance in cystic fibrosis. SEARCH STRATEGY: Relevant trials are identified in the Cochrane Cystic Fibrosis and Genetic Disorders Group Specialised Register of Controlled Trials. This register was compiled by conducting computerised searches of Medline from 1966 to present and from Embase from 1974 to 1995. The register of randomised controlled trials is updated every three months. Unpublished work has been identified by searching through the abstract books of the three major cystic fibrosis conferences; the International Cystic Fibrosis Conference: the European Cystic Fibrosis Conference and the North American Cystic Fibrosis Conference. Date of the most recent search of the Group's specialised register: November 1999. SELECTION CRITERIA: Randomised or quasi-randomised clinical trials in which a form of chest physiotherapy (airway clearance technique) were taken for consideration in patients with cystic fibrosis compared with either no physiotherapy treatment or spontaneous cough alone. DATA COLLECTION AND ANALYSIS: There were no randomised controlled trials or cross over trials eligible for inclusion in the review. MAIN RESULTS: There were no randomised controlled trials or cross over trials eligible for inclusion in the review. REVIEWER'S CONCLUSIONS: Short-term crossover trials, which had to be excluded from this review, suggest that airway clearance regimens could have beneficial effects in patients with cystic fibrosis. However based on this review there is currently no robust scientific evidence to support the hypothesis that chest physiotherapy for the purpose of clearing airway secretions has a beneficial effect in patients with cystic fibrosis.

Evidence for physiotherapy practice: a survey of the Physiotherapy Evidence Database (PEDro).

Evidence-based practice involves the use of evidence from systematic reviews and randomised controlled trials, but the extent of this evidence in physiotherapy has not previously been surveyed. The aim of this survey is to describe the quantity and quality of randomised controlled trials and the quantity of systematic reviews relevant to physiotherapy. The Physiotherapy Evidence Database (PEDro) was searched. The quality of trials was assessed with the PEDro scale. The search identified a total of 2,376 randomised controlled trials and 332 systematic reviews. The first trial was published in 1955 and the first review was published in 1982. Since that time, the number of trials and reviews has grown exponentially. The mean PEDro quality score has increased from 2.8 in trials published between 1955 and 1959 to 5.0 for trials published between 1995 and 1999. There is a substantial body of evidence about the effects of physiotherapy. However, there remains scope for improvements in the quality of the conduct and reporting of clinical trials.

Making physiotherapy more accessible: open access for general practitioners to a physiotherapy department.

Open access to a physiotherapy outpatient department of a district general hospital was offered to general practitioners to whom domiciliary physiotherapy was already available. The effects of the new service have been monitored. Delays are reduced and consultants economise on time spent in merely confirming need for physiotherapy. Policies determining treatment, placing emphasis on prevention and self-help rather than prolonged treatment, are adhered to equally well by physiotherapists whether patients are referred directly or indirectly. It had proved unnecessary to restrict access to physiotherapy by insisting that general practitioners refer all patients first to consultant clinics. General practitioners have been sufficiently selective in referral and physiotherapists sufficiently economical in selecting treatment and determining its duration for the service to remain within the limits of available resources.

Is undergraduate physiotherapy study a risk factor for low back pain? A prevalence study of LBP in physiotherapy students.

BACKGROUND: Following reports of high prevalence of low back pain (LBP) in young physiotherapists, we investigated whether LBP was a problem for undergraduate physiotherapy students. METHOD: Physiotherapy students enrolled in one Australian tertiary institution completed a validated self-administered questionnaire in April 2001, seeking information on LBP prevalence (lifetime, 12 month, one-month, one-week), and its risk factors. The survey incorporated the Nordic back questionnaire, questions on common risks for LBP, and purpose-built questions regarding educational exposures. Univariate logistic regression models were applied to test associations. RESULTS AND DISCUSSION: 72% students responded. LBP prevalence was 69% (lifetime), 63% (12-month), 44% (one-month), 28% (one-week). The risk of LBP increased significantly for students once they completed first year. Being aged 20 or 21 years (final year students) was significantly associated with all measures of LBP, compared with the youngest students. Exposure to tertiary study of greater than two years was associated with lifetime, 12 month and one-month LBP prevalence. Spending more than 20 hours in the past month 'sitting looking down' was significantly associated with one-month LBP prevalence. Similar exposure to 'treating patients' was significantly associated with one-month and one-week LBP prevalence. CONCLUSIONS: Physiotherapy students should be alerted to the likelihood of LBP and is potential causes during their training, so that they enter the workforce with reduced risk of LBP. The potential for other undergraduate students to suffer LBP should also be considered.

Biofeedback and physiotherapy versus physiotherapy alone in the treatment of genuine stress urinary incontinence.

Biofeedback is a method of pelvic floor rehabilitation using a surface electrode inserted into the vagina and a catheter in the rectum. Forty women with genuine urinary stress incontinence were randomized to compare the efficacy of physiotherapy and physiotherapy in combination with biofeedback. The effect of the treatment was determined by a standardized pad-weighing test. Long-term status was determined using a questionnaire after 2-3 years. Thirty-four women completed the treatment. The study showed a statistically significant better improvement in the biofeedback group. The long-term effect in the biofeedback group seemed better and the patients were more motivated for training afterwards.

Follow-up of children with cerebral palsy after selective posterior rhizotomy with intensive physiotherapy or physiotherapy alone.

In all 21 children with spastic cerebral palsy (CP) underwent surgery involving selective posterior rhizotomy (SPR), followed by six months intensive physiotherapy (PT). Neurological and physiotherapeutic assessments were made one, three and five years after the operation. The children undergoing surgery were compared to 21 comparison children who took part in a regular physiotherapy programme during the same time period. At the preoperative assessment, the children undergoing surgery were similar to the comparative children in terms of age, sex, type of CP, spasticity of the legs and mean functional scores. The children were selected for SPR on the basis of more than half a year's arrest of motor development, which was the only significant difference to the comparative group. Motor function was measured using two different methods, the Illinois-St Louis Scale and the Gross Motor Functional Classification System (GMFC). Both groups experienced steady development during the five-year follow-up period and no significant differences were observed in the mean functional scores between the groups. We conclude that this comparative study, like most controlled studies, failed to demonstrate any additional effect of SPR on motor development of children with spastic CP. Nevertheless, SPR may contribute to a resumption of motor development in children with arrested motor development despite vigorous conservative therapy. SPR is therefore justified as treatment in selected cases.

Randomized trial of two physiotherapy interventions for primary care neck and back pain patients: 'McKenzie' vs brief physiotherapy pain management.

OBJECTIVES: Interventions that take psychosocial factors into account are recommended for patients with persistent back or neck pain. We compared the effectiveness of a brief physiotherapy pain management approach using cognitive-behavioural principles (Solution-Finding Approach-SFA) with a commonly used method of physical therapy (McKenzie Approach-McK). METHODS: Eligible patients referred by GPs to physiotherapy departments with neck or back pain lasting at least 2 weeks were randomized to McK (n= 161) or to SFA (n= 154). They were further randomized to receive an educational booklet or not. The primary outcome was the Tampa Scale of Kinesiophobia (TSK) (Activity-Avoidance scale used as a proxy for coping) at 6 weeks, and 6 and 12 months. RESULTS: Of 649 patients assessed for eligibility, 315 were recruited (219 with back pain, 96 with neck pain). There were no statistically significant differences in outcomes between the groups, except that at any time point SFA patients supported by a booklet reported less reliance on health professionals (Multidimensional Health Locus of Control Powerful Others Scale), while at 6 months McK patients showed slightly more improvement on activity-avoidance (TSK). At 6 weeks, patient satisfaction was greater for McK (median 90% compared with 70% for SFA). Both interventions resulted in modest but clinically important improvements over time on the Roland Disability Questionnaire Scores and Northwick Park Neck Pain Scores. CONCLUSIONS: The McK approach resulted in higher patient satisfaction overall but the SFA could be more cost-effective, as fewer (three vs four) sessions were needed.

Is acupuncture a useful adjunct to physiotherapy for older adults with knee pain?: the "acupuncture, physiotherapy and exercise" (APEX) study [ISRCTN88597683].

BACKGROUND: Acupuncture is a popular non-pharmacological modality for treating musculoskeletal pain. Physiotherapists are one of the largest groups of acupuncture providers within the NHS, and they commonly use it alongside advice and exercise. Conclusive evidence of acupuncture's clinical effectiveness and its superiority over sham interventions is lacking. The Arthritis Research Campaign (arc) has funded this randomised sham-controlled trial which addresses three important questions. Firstly, we will determine the additional benefit of true acupuncture when used by physiotherapists alongside advice and exercise for older people presenting to primary care with knee pain. Secondly, we will evaluate sham acupuncture in the same way. Thirdly, we will investigate the treatment preferences and expectations of both the participants and physiotherapists participating in the study, and explore the effect of these on clinical outcome. We will thus investigate whether acupuncture is a useful adjunct to advice and exercise for treating knee pain and gain insight into whether this effect is due to specific needling properties. METHODS/DESIGN: This randomised clinical trial will recruit 350 participants with knee pain to three intervention arms. It is based in 43 community physiotherapy departments in 21 NHS Trusts in the West Midlands and Cheshire regions in England. Patients aged 50 years and over with knee pain will be recruited. Outcome data will be collected by self-complete questionnaires before randomisation, and 6 weeks, 6 months and 12 months after randomisation and by telephone interview 2 weeks after treatment commences. The questionnaires collect demographic details as well as information on knee-related pain, movement and function, pain intensity and affect, main functional problem, illness perceptions, self-efficacy, treatment preference and expectations, general health and quality of life. Participants are randomised to receive a package of advice and exercise; or this package plus real acupuncture; or this package plus sham acupuncture. Treatment details are being collected on a standard proforma. Interventions are delivered by experienced physiotherapists who have all received training in acupuncture to recognised national standards. The primary analysis will investigate the main treatment effects of real or sham acupuncture as an adjunct to advice and exercise. DISCUSSION: This paper presents detail on the rationale, design, methods, and operational aspects of the trial.

Perspectives on the physiotherapy profession: a survey of Canadian Physiotherapy Association members.

This study was designed to assess the professional satisfaction of a national sample of physiotherapists, all members of the Canadian Physiotherapy Association (CPA). A questionnaire was sent to 984 CPA members; 82.1% responded. Rather than analyzing the satisfaction items separately, the investigators used factor analysis to search for underlying structures in the responses. The principal component analysis indicated that there were four discrete patterns of covariation in the responses, and the resulting factors were labelled "professional interests," "patient care", "supervision" and "work conditions", in accordance with the content of the items grouped into each factor. The combination of these cores plus the results of a global ranking of the profession indicated a consistently high level of overall satisfaction on the part of the CPA therapists. As for characteristics and career patterns, the female CPA members appeared to move in an out of professional practice while the male members pursued careers. The reasons for the low level of professional satisfaction on the part of an albeit small minority of physiotherapists were found to be associated with dissatisfaction with working conditions. Further research is required to relate physiotherapists' satisfaction with their profession to their career decisions.
