ABSTRACT

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is recognized as a systemic illness with significant extra-pulmonary features, such as exercise intolerance and muscle weakness. Pulmonary rehabilitation has been shown to be very effective in counteracting these consequences in patients with more advanced COPD. However, limited data is available on the efficacy of a physical exercise training programme in patients with mild to moderate COPD in primary care. Furthermore, it is unknown if improved exercise capacity translates into enhanced daily physical activities. The aim of this paper is to describe the design of a randomized controlled trial to assess the efficacy of a physical exercise training programme in patients with mild to moderate COPD. METHODS/DESIGN: In this randomized controlled trial situated in the primary care setting, 102 patients with mild to moderate airflow obstruction (FEV1 ≥ 50% of predicted), dyspnoea and a physically inactive lifestyle will be randomized to an intervention or control group. The intervention group receives a 4-month physical exercise training programme at a local physiotherapy practice, which includes exercise training, resistance training, breathing exercises and advises on how to increase the level of physical activity. The control group receives usual care, i.e. advises on how to increase the level of physical activity and a sham treatment at a local physiotherapy practice of which no physiological training stimulus can be expected. Primary outcome is functional exercise capacity at 4-months measured on the six-minute walk distance. Secondary outcomes include peripheral muscle strength, physical activity in daily life, health related quality of life, Medical Research Council (MRC) dyspnoea score and patients' perceived effectiveness. Follow-up measurement will take place at 6 months after baseline. DISCUSSION: This will be one of the first studies to evaluate the efficacy of a physical exercise training programme in patients with mild to moderate COPD completely recruited and assessed in primary care. The results of this trial may give a unique insight into the potential of the implementation of an easy, close-to-home rehabilitation programme. TRIAL REGISTRATION: The Netherlands National Trial Register NTR1471.

ABSTRACT

BACKGROUND: Physical exercise training aims at reducing disease-specific impairments and improving quality of life in patients with chronic obstructive pulmonary disease (COPD). COPD exacerbations in particular negatively impact COPD progression. Physical therapy intervention seems indicated to influence exacerbations and their consequences. However, information on the effect of physical therapy on exacerbation occurrence is scarce. This study aims to investigate the potential of a protocol-directed physical therapy programme as a means to prevent or postpone exacerbations, to shorten the duration or to decrease the severity of exacerbations in patients with COPD who have recently experienced an exacerbation. Besides, this study focuses on the effect of protocol-directed physical therapy on health status and quality of life and on cost-effectiveness and cost-utility in patients with COPD who have recently experienced an exacerbation. METHODS/DESIGN: A prospective cohort of 300 COPD patients in all GOLD stages will be constructed. Patients will receive usual multidisciplinary COPD care including guideline-directed physical therapy. Patients in this cohort who have GOLD stage 2 to 4 (post-bronchodilator FEV1/FVC < 0.7 and FEV1 < 80% of predicted), who receive reimbursement by health insurance companies for physical therapy (post-bronchodilator Tiffeneau-index < 0.6) and who experience a COPD exacerbation will be asked within 56 days to participate in a cohort-nested prospective randomised controlled trial (RCT). In this RCT, the intervention group will receive a strict physical therapy programme for patients with COPD. This protocol-directed physical therapy (pdPT) will be compared to a control group that will receive sham-treatment, meaning no or very low-intensity exercise training (ST). An economic evaluation will be embedded in the RCT. Anthropometric measurements, comorbidities, smoking, functional exercise capacity, peripheral muscle strength, physical activity level, health related quality of life, patients' perceived benefit, physical therapy compliance, motivation level, level of effective mucus clearance, exacerbation symptoms and health care contacts due to COPD will be recorded. Follow-up measurements are scheduled at 3 and 6 weeks, 3, 6, 12 and 24 months after inclusion. DISCUSSION: Ways to minimise potential problems regarding the execution of this study will be discussed. TRIAL REGISTRATION: The Netherlands National Trial Register NTR1972.

ABSTRACT

OBJECTIVE: To evaluate measurement properties of a set of public quality indicators on physical therapy. DESIGN: An observational study with web-based collected survey data (2009 and 2010). SETTING: Dutch primary care physical therapy practices. PARTICIPANTS: In 3743 physical therapy practices, 11 274 physical therapists reporting on 30 patients each. MAIN OUTCOME MEASURES: Eight quality indicators were constructed: screening and diagnostics (n= 2), setting target aim and subsequent of intervention (n = 2), administrating results (n = 1), global outcome measures (n = 2) and patient's treatment agreement (n = 1). Measurement properties on content and construct validity, reproducibility, floor and ceiling effects and interpretability of the indicators were assessed using comparative statistics and multilevel modeling. RESULTS: Content validity was acceptable. Construct validity (using known group techniques) of two outcome indicators was acceptable; hypotheses on age, gender and chronic vs. acute care were confirmed. For the whole set of indicators reproducibility was approximated by correlation of 2009 and 2010 data and rated moderately positive (Spearman's ρ between 0.3 and 0.42 at practice level) and interpretability as acceptable, as distinguishing between patient groups was possible. Ceiling effects were assessed negative as they were high to extremely high (30% for outcome indicator 6-95% for administrating results). CONCLUSION: Weaknesses in data collection should be dealt with to reduce bias and to reduce ceiling effects by randomly extracting data from electronic medical records. More specificity of the indicators seems to be needed, and can be reached by focusing on most prevalent conditions, thus increasing usability of the indicators to improve quality of care.

ABSTRACT

RATIONALE: As primary care practice space is mostly limited to 10 m, the 6-minute walk test (6MWT) over a 10 m course is a frequently used alternative to evaluate patients' performance in COPD. Considering that course length significantly affects distance walked in 6 minutes (6MWD), this study aims to develop appropriate reference equations for the 10 m 6MWT. METHODS: 181 healthy subjects, aged 40-90 years, performed two standardised 6MWTs over a straight 10 m course in a cross-sectional study. RESULTS: Average distance achieved was 578±108 m and differed between males and females (p<0.001). Resulting sex-specific reference equations from multiple regression analysis included age, body mass index and change in heart rate, explaining 62% of the variance in 6MWD for males and 71% for females. CONCLUSIONS: The presented reference equations are the first to evaluate 6MWD over a 10 m course and expand the usefulness of the 6MWT.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Stress urinary incontinence (SUI) is the most common form of incontinence impacting on quality of life (QOL) and is associated with high financial, social, and emotional costs. The purpose of this study was to provide an update existing Dutch evidence-based clinical practice guidelines (CPGs) for physiotherapy management of patients with stress urinary incontinence (SUI) in order to support physiotherapists in decision making and improving efficacy and uniformity of care. MATERIALS AND METHODS: A computerized literature search of relevant databases was performed to search for information regarding etiology, prognosis, and physiotherapy assessment and management in patients with SUI. Where no evidence was available, recommendations were based on consensus. Clinical application of CPGs and feasibility were reviewed. The diagnostic process consists of systematic history taking and physical examination supported by reliable and valid assessment tools to determine physiological potential for recovery. Therapy is related to different problem categories. SUI treatment is generally based on pelvic floor muscle exercises combined with patient education and counseling. An important strategy is to reduce prevalent SUI by reducing influencing risk factors. RESULTS: Scientific evidence supporting assessment and management of SUI is strong. CONCLUSIONS: The CPGs reflect the current state of knowledge of effective and tailor-made intervention in SUI patients.

ABSTRACT

QUESTIONS: Do patients with chronic obstructive pulmonary disease (COPD) achieve a different distance on the six minute walk test (6MWT) conducted on a 10m course versus on a 30m course? When assessing the distance on a 6MWT conducted on a 10m course, is it valid to use existing reference equations that were generated on longer courses? DESIGN: A randomised double-crossover experimental study. PARTICIPANTS: Forty-five patients with COPD in primary physiotherapy care. INTERVENTION: All patients performed a 6MWT twice over a 10m course and twice over a 30m course. The 6MWTs were performed in accordance with the American Thoracic Society guidelines. OUTCOME MEASURES: 6MWD was assessed and predicted distance was calculated based on a range of reference equations. RESULTS: The 6MWD on the 10m course was 49.5m shorter than on the 30m course, which was statistically significant (95% CI 39.4 to 59.6). By using existing reference equations for a 6MWT conducted on the 10m course, the predicted distance is highly overestimated (with a range of 30% to 33%) and the average distance as a percentage of the predicted value is 8%pred lower compared to a 6MWT conducted on the 30m course, resulting in a worse representation of a COPD patient's functional exercise capacity. CONCLUSION: This study shows that the impact of course length on the 6MWD and on the use of reference equations in patients with COPD is substantial and clinically relevant (based on the most conservative published minimum clinically important difference). Therefore, existing reference equations established for a 6MWT conducted over a 30m (or longer) course cannot be applied to predict the distance achieved on the 6MWT on a 10m course, which is frequently used in primary care physiotherapy practices for patients with COPD.

ABSTRACT

BACKGROUND: Clinical practice guidelines have been developed to assist healthcare practitioners in clinical decision making. Publication of clinical practice guidelines does not automatically lead to their uptake and barrier identification has been recognized as an important step in implementation planning. This study aimed at developing a questionnaire to identify perceived barriers for implementing the Dutch COPD guideline for physical therapists and its recommended measurement instruments. METHODS: An overall questionnaire, based on two existing questionnaires, was constructed to identify barriers and facilitators for implementing the COPD guideline. The construct of the questionnaire was assessed in a cross-sectional study among 246 chest physical therapists. Factor analysis was conducted to explore underlying dimensions. Psychometric properties were analyzed using Cronbach's alpha. Barriers and facilitators were assessed using descriptive statistics. RESULTS: Some 139 physical therapists (57%) responded. Factor analysis revealed 4-factor and 5-factor solutions with an explained variance of 36% and 39% respectively. Cronbach's alpha of the overall questionnaire was 0.90, and varied from 0.66 to 0.92 for the different factors. Underlying domains of the 5-factor solution were characterized as: attitude towards using measurement instruments, knowledge and skills of the physical therapist, applicability of the COPD guideline, required investment of time & money, and patient characteristics. Physical therapists showed a positive attitude toward using the COPD guideline. Main barriers for implementation were required time investment and financial constraints. CONCLUSIONS: The construct of the questionnaire revealed relevant underlying domains for the identification of barriers and facilitators for implementing the COPD guideline. The questionnaire allowed for tailoring to the target group and may be used across health care professionals as basis for in-depth analysis of barriers to specific recommendations in guidelines. The results of the questionnaire alone do not provide sufficient information to inform the development of an implementation strategy. The infrastructure for developing the guideline can be used for addressing key barriers by the guideline development group, using the questionnaire as well as in-depth analysis such as focus group interviews. Further development of methods for prospective identification of barriers and consequent tailoring of implementation interventions is required.

ABSTRACT

INTRODUCTION: Intermittent claudication (IC) is a manifestation of peripheral arterial occlusive disease (PAOD). Besides cardiovascular risk management, supervised exercise therapy (SET) should be offered to all patients with IC. Outdated guidelines, an insufficient number of specialized physiotherapists (PTs), lack of awareness of the importance of SET by referring physicians, and misguided financial incentives all seriously impede the availability of a structured SET program in The Netherlands. DESCRIPTION OF CARE PRACTICE: By initiating regional care networks, ClaudicatioNet aims to improve the quality of care for patients with IC. Based on the chronic care model as a conceptual framework, these networks should enhance the access, continuity, and (cost) efficiency of the health care system. With the aid of a national database, health care professionals will be able to benchmark patient results while ClaudicatioNet will be able to monitor quality of care by way of functional and patient reported outcome measures. DISCUSSION: The success of ClaudicatioNet is dependent on several factors. Vascular surgeons, general practitioners and coordinating central caregivers will need to team up and work in close collaboration with specialized PTs. A substantial task in the upcoming years will be to monitor the quality, volume, and distribution of ClaudicatioNet PTs. Finally, misguided financial incentives within the Dutch health care system need to be tackled. CONCLUSION: With ClaudicatioNet, integrated care pathways are likely to improve in the upcoming years. This should result in the achievement of optimal quality of care for all patients with IC.

ABSTRACT

Intermittent claudication (IC) has a high prevalence in the older population and is closely associated with cardiovascular and cerebrovascular disease. High mortality rates are reported due to ongoing atherosclerotic disease. Because of these serious health risks, treatment of IC should address reduction of cardiovascular events (and related morbidity/mortality) and improvement of the poor health-related quality of life (QoL) and functional capacity. In several randomized clinical trials and systematic reviews, supervised exercise therapy (SET) is compared with non-supervised exercise, usual care, placebo, walking advice or vascular interventions. The current evidence supports SET as the primary treatment for IC. SET improves maximum walking distance and health-related QoL with a marginal risk of co-morbidity or mortality. This is also illustrated in contemporary international guidelines. Community-based SET appears to be at least as efficacious as programs provided in a clinical setting. In the Netherlands, a national integrated care network (ClaudicatioNet) providing specialized care for patients with IC is currently being implemented. Besides providing a standardized form of SET, the specialized physical therapists stimulate medication compliance and perform lifestyle coaching. Future research should focus on the influence of co-morbidities on prognosis and effect of SET outcome and the potential beneficial effects of SET combined with a vascular intervention.

ABSTRACT

QUESTION: What are the effects of strength training alone, exercise therapy alone, and exercise with additional passive manual mobilisation on pain and function in people with knee osteoarthritis compared to control? What are the effects of these interventions relative to each other? DESIGN: A meta-analysis of randomised controlled trials. PARTICIPANTS: Adults with osteoarthritis of the knee. INTERVENTION TYPES: Strength training alone, exercise therapy alone (combination of strength training with active range of motion exercises and aerobic activity), or exercise with additional passive manual mobilisation, versus any non-exercise control. Comparisons between the three interventions were also sought. OUTCOME MEASURES: The primary outcome measures were pain and physical function. RESULTS: 12 trials compared one of the interventions against control. The effect size on pain was 0.38 (95% CI 0.23 to 0.54) for strength training, 0.34 (95% CI 0.19 to 0.49) for exercise, and 0.69 (95% CI 0.42 to 0.96) for exercise plus manual mobilisation. Each intervention also improved physical function significantly. No randomised comparisons of the three interventions were identified. However, meta-regression indicated that exercise plus manual mobilisations improved pain significantly more than exercise alone (p = 0.03). The remaining comparisons between the three interventions for pain and physical function were not significant. CONCLUSION: Exercise therapy plus manual mobilisation showed a moderate effect size on pain compared to the small effect sizes for strength training or exercise therapy alone. To achieve better pain relief in patients with knee osteoarthritis physiotherapists or manual therapists might consider adding manual mobilisation to optimise supervised active exercise programs.

ABSTRACT

BACKGROUND: The first-line intervention for intermittent claudication is usually supervised exercise therapy (SET). The literature describes a range of exercise programs varying in setting, duration, and content. The purpose of the present study was to examine the exercise protocols offered and to identify the impact of the intensity of the SET programs (in terms of frequency, duration, and type of exercise) on improvements in walking distance (response) in the first 3 months. The present study is part of the Exercise Therapy in Peripheral Arterial Disease (EXITPAD) study, a multicenter randomized clinical trial comparing the effects of SET provided by regional physiotherapists, with or without daily feedback, on the level of activities with the effects of walking advice. METHODS: The analysis included patients randomized to receive SET with or without feedback. The physical therapists administering the SET were asked to fill out therapy evaluation sheets stating frequency, duration, and type of exercises. The relationship between training volume and the impact on walking distance was explored by dividing training volume data into tertiles and relating them to the median change in maximum walking distance at 3 and 12 months. RESULTS: Data of 169 patients were included in the analysis. A SET program consisting of at least two training sessions per week each lasting over 30 minutes, during the first 3 months of a 1-year program tailored to individual patients' needs led to better results in terms of walking distance after 3 and 12 months than the other variants. The results of our analysis dividing training volume into tertiles suggest that there is a relationship between training volume and improvement in walking distance and that at least 590 minutes of training should be offered in the first 3 months. No differences were found between program involving only walking and a combination of exercises, nor between individual and group training. CONCLUSION: A SET programs consisting of at least two training sessions a week, each lasting over 30 minutes, should be offered during the first 3 months of the SET program to optimize improvement in terms of maximum walking distance.

ABSTRACT

BACKGROUND: Conflicting results are reported about the contribution of maternal, obstetric and fetal characteristics to postpartum fecal incontinence (FI), which is hampering prevention and management of FI. OBJECTIVE: To perform a systematic review identifying delivery-related etiological factors for postpartum FI. Search strategy. Literature searches of PubMed, EMBASE, CINAHL, DocOnline and reference lists from 1980 up to 2009 were conducted. Selection criteria. Prospective cohort studies evaluating maternal, obstetric or fetal risk factors for postpartum FI, with a follow-up period of at least three months, were assessed. We reviewed full reports in English, German or Dutch, with anal incontinence (AI), FI, flatus incontinence, soiling, urgency and FI severity scores as reported outcomes. Data collection and analysis. Data on study characteristics, methodological quality and outcome were extracted from 31 studies according to a standardized protocol. Clinical and methodological sources of heterogeneity permitted only a qualitative analysis. MAIN RESULTS: A third- or fourth-degree sphincter rupture was the only etiological factor strongly (AI) or moderately (flatus incontinence) associated with postpartum FI. No association with other postulated risk factors was found, for example, birth weight or instrumental delivery. The potential co-existence of different risk factors impedes the interpretation of the influence of a single delivery-related risk factor. CONCLUSIONS: This systematic review, including only longitudinal studies and recognizing the importance of separating results for different outcomes, identifies that a third- or fourth-degree sphincter rupture is the only factor that is strongly (AI) or moderately (flatus incontinence) associated with postpartum FI.

ABSTRACT

OBJECTIVE: Determining "minimally important change" (MIC) facilitates the interpretation of change scores on multi-item instruments. This article focuses on how MIC values should be interpreted when applied to individual patients. STUDY DESIGN AND SETTING: The MIC value of a hypothetical questionnaire "Q" was determined in a sample of 400 patients who improved and 100 patients who did not improve, using the receiver operating characteristic (ROC) method, and three methods to quantify the uncertainty. RESULTS: The MIC value on questionnaire Q was 10.5. Firstly, the 95% confidence interval (CI) of the MIC value (for questionnaire Q: 5.6-14.2) quantifies the uncertainty of the estimation of the MIC value. Secondly, "how sure we are that this MIC value holds for every patient" is quantified by the values for sensitivity (74%) and specificity (91%). Thirdly, the smallest detectable change (SDC) on questionnaire Q is calculated (16.0) to consider whether the MIC value (10.5) falls outside or within the measurement error. CONCLUSION: For application in clinical research and practice, MIC values are always considered at the individual level, but determined in groups of patients. The interpretation comes with different forms of uncertainty. To appreciate the uncertainty, knowledge of the underlying distributions of change scores is indispensable.

ABSTRACT

AIM: To determine the psychometric properties of the total Vaizey score and its individual items. METHODS: The study was conducted as part of a prospective cohort study assessing the outcome of pelvic floor rehabilitation in patients with fecal incontinence. RESULTS: One hundred ninety-four patients were analyzed, 53 of whom provided data on the global perceived effect (GPE) score. Pelvic floor rehabilitation resulted in a significant reduction of the total Vaizey score and most individual items. The total Vaizey scores changed in agreement with the GPE scores. The total Vaizey score was responsive, but some individual items yielded inconsistent results for three different measures. The test-retest reliability was adequate or excellent for six individual items and the total Vaizey score. The internal consistency was low for the total Vaizey score at baseline, in contrast to the follow-up and change scores. The estimates for the minimally important change (MIC) and smallest detectable change yielded moderately consistent results. An MIC of -5 points seemed preferable and yielded the lowest misclassification rate. CONCLUSIONS: More research is required to confirm conclusions on the psychometric properties of the total Vaizey score and its individual items, and to justify its use in research and routine clinical practice.

ABSTRACT

AIMS: To identify prognostic indicators independently associated with poor outcome of physiotherapy intervention in women with primary or recurrent stress urinary incontinence (stress UI). METHODS: A prospective cohort study was performed in physiotherapy practices in primary care to identify prognostic indicators 12 weeks after initiation of physiotherapy intervention. Patients were referred by general practitioners or urogynecologists. Risk factors for stress UI were examined as potential prognostic indicators of poor outcome. The primary outcomes were defined as poor outcome on the binary Leakage Severity scale (LS scale) and the binary global perceived effectiveness (GPE) score. RESULTS: Two hundred sixty-seven women, with a mean age of 47.7 (SD = 8.3), with stress UI for at least 6 months were included. At 12 weeks, 43% and 59% of the women were considered recovered on the binary LS scale and the binary GPE score, respectively. Prognostic indicators associated with poor outcome included 11 indicators based on the binary LS scale and 8 based on the binary GPE score. The prognostic indicators shared by both models show that poor recovery was associated with women with severe stress UI, POP-Q stage > II, poor outcome of physiotherapy intervention for a previous UI episode, prolonged second stage of labor, BMI > 30, high psychological distress, and poor physical health. CONCLUSIONS: This study provides robust evidence of clinically meaningful prognostic indicators of poor short-term outcome. These findings need to be confirmed by replication studies.

ABSTRACT

The objective of this study was to report on secondary analyses of a merged trial dataset aimed at exploring the potential importance of patient factors associated with clinically relevant improvements in non-acute, non-specific low back pain (LBP). From 273 predominantly male army workers (mean age 39 +/- 10.5 years, range 20-56 years, 4 women) with LBP who were recruited in three randomized clinical trials, baseline individual patient factors, pain-related factors, work-related psychosocial factors, and psychological factors were evaluated as potential prognostic variables in a short-term (post-treatment) and a long-term logistic regression model (6 months after treatment). We found one dominant prognostic factor for improvement directly after treatment as well as 6 months later: baseline functional disability, expressed in Roland-Morris Disability Questionnaire scores. Baseline fear of movement, expressed in Tampa Scale for Kinesiophobia scores, had also significant prognostic value for long-term improvement. Less strongly associated with the outcome, but also included in our final models, were supervisor social support and duration of complaints (short-term model), and co-worker social support and pain radiation (long-term model). Information about initial levels of functional disability and fear-avoidance behaviour can be of value in the treatment of patient populations with characteristics comparable to the current army study population (e.g., predominantly male, physically active, working, moderate but chronic back problems). Individuals at risk for poor long-term LBP recovery, i.e., individuals with high initial level of disability and prominent fear-avoidance behaviour, can be distinguished that may need additional cognitive-behavioural treatment.

ABSTRACT

QUESTION: What is the effectiveness of strategies to increase the implementation of physiotherapy clinical guidelines? DESIGN: Systematic review. PARTICIPANTS: Physiotherapists treating any type of patients. INTERVENTION: Single or multiple strategies to increase the implementation of physiotherapy clinical guidelines. OUTCOME MEASURES: Professional practice, patient health, and cost of care. RESULTS: Five papers reporting three cluster-randomised trials evaluated whether multifaceted strategies based on educational meetings increased the implementation of low back pain guidelines (2 trials) or whiplash guidelines (1 trial). Educational meetings were effective in increasing adherence to the following recommendations of low back pain guidelines: limiting the number of sessions (RD 0.13, 95% CI 0.03 to 0.23), using active intervention (RD 0.13, 95% CI 0.05 to 0.21), giving adequate information (RD 0.05, 95% CI 0.00 to 0.11), increasing activity level (RD 0.16, 95% CI 0.02 to 0.30), changing attitudes/beliefs about pain (RD 0.13, 95% CI 0.01 to 0.24). Educational meetings were effective in increasing adherence to the following recommendations of whiplash guidelines: reassuring the patient (RD 0.40, 95% CI 0.07 to 0.74), advising the patient to act as usual (RD 0.48, 95% CI 0.15 to 0.80), using functional outcome measures (RD 0.62, 95% CI 0.32 to 0.92). There was no evidence that patient health was improved or that the cost of care was reduced. CONCLUSION: This review shows that multifaceted interventions based on educational meetings to increase implementation of clinical guidelines may improve some outcomes of professional practice but do not improve patient health or reduce cost of care. These findings are comparable with results among other health professions.

ABSTRACT

BACKGROUND: Neck pain is a significant health problem in modern society. There is evidence to suggest that neck muscle strength is reduced in patients with neck pain. This article provides a critical analysis of the research literature on the clinimetric properties of tests to measure neck muscle strength or endurance in patients with non-specific neck pain, which can be used in daily practice. METHODS: A computerised literature search was performed in the Medline, CINAHL and Embase databases from 1980 to January 2007. Two reviewers independently assessed the clinimetric properties of identified measurement methods, using a checklist of generally accepted criteria for reproducibility (inter- and intra-observer reliability and agreement), construct validity, responsiveness and feasibility. RESULTS: The search identified a total of 16 studies. The instruments or tests included were: muscle endurance tests for short neck flexors, craniocervical flexion test with an inflatable pressure biofeedback unit, manual muscle testing of neck musculature, dynamometry and functional lifting tests (the cervical progressive iso-inertial lifting evaluation (PILE) test and the timed weighted overhead test). All the articles included report information on the reproducibility of the tests. Acceptable intra- and inter-observer reliability was demonstrated for t enduranctest for short neck flexors and the cervical PILE test. Construct validity and responsiveness have hardly been documented for tests on muscle functioning. CONCLUSION: The endurance test of the short neck flexors and the cervical PILE test can be regarded as appropriate instruments for measuring different aspects of neck muscle function in patients with non-specific neck pain. Common methodological flaws in the studies were their small sample size and an inappropriate description of the study design.

ABSTRACT

The study is to provide a critical analysis of the research literature on clinimetric properties of instruments that can be used in daily practice to measure active cervical range of motion (ACROM) in patients with non-specific neck pain. A computerized literature search was performed in Medline, Cinahl and Embase from 1982 to January 2007. Two reviewers independently assessed the clinimetric properties of identified instruments using a criteria list. The search identified a total of 33 studies, investigating three different types of measurement instruments to determine ACROM. These instruments were: (1) different types of goniometers/inclinometers, (2) visual estimation, and (3) tape measurements. Intra- and inter-observer reliability was demonstrated for the cervical range of motion instrument (CROM), Cybex electronic digital instrument (EDI-320) and a single inclinometer. The presence of agreement was assessed for the EDI-320 and a single inclinometer. The CROM received a positive rating for construct validity. When clinical acceptability is taken into account both the CROM and the single inclinometer can be considered appropriate instruments for measuring the active range of motion in patients with non-specific neck pain in daily practice. Reliability is the aspect most frequently evaluated. Agreement, validity and responsiveness are documented less frequently.
