A prospective double blind placebo-controlled randomized trial of ultrasound in the physiotherapy treatment of shoulder pain.

OBJECTIVE: To compare the effectiveness of manual therapy and ultrasound (US) with manual therapy and placebo ultrasound (placebo US) in the treatment of new episodes of unilateral shoulder pain referred for physiotherapy. METHODS: In a multicentre, double blind, placebo-controlled randomized trial, participants were recruited with a clinical diagnosis of unilateral shoulder pain from nine primary care physiotherapy departments in Birmingham, UK. Recruitment took place from January 1999 to September 2001. Participants were 18 yrs old and above. Participants all received advice and home exercises and were randomized to additionally receive manual therapy plus US or manual therapy plus placebo US. The primary outcome measure was the Shoulder Disability Questionnaire (SDQ-UK). Outcomes were assessed at baseline, 2 weeks, 6 weeks and 6 months. Analysis was by intention to treat. RESULTS: A total of 221 participants (mean age 56 yrs) were recruited. 113 participants were randomized to US and 108 to placebo US. There was 76% follow up at 6 weeks and 71% at 6 months. The mean (95% CI) reduction in SDQ scores at 6 weeks was 17 points (13-26) for US and 13 points (9-17) for placebo US (P = 0.06). There were no statistically significant differences at the 5% level in mean changes between groups at any of the time points. CONCLUSIONS: The addition of US was not superior to placebo US when used as part of a package of physiotherapy in the short-term management of shoulder pain. This has important implications for physiotherapy practice.

EULAR evidence based recommendations for the management of hand osteoarthritis: report of a Task Force of the EULAR Standing Committee for International Clinical Studies Including Therapeutics (ESCISIT).

OBJECTIVES: To develop evidence based recommendations for the management of hand osteoarthritis (OA). METHODS: The multidisciplinary guideline development group comprised 16 rheumatologists, one physiatrist, one orthopaedic surgeon, two allied health professionals, and one evidence based medicine expert, representing 15 different European countries. Each participant contributed up to 10 propositions describing key clinical points for management of hand OA. Final recommendations were agreed using a Delphi consensus approach. A systematic search of Medline, Embase, CINAHL, Science Citation Index, AMED, Cochrane Library, HTA, and NICE reports was used to identify the best available research evidence to support each proposition. Where possible, the effect size and number needed to treat were calculated for efficacy. Relative risk or odds ratio was estimated for safety, and incremental cost effectiveness ratio was used for cost effectiveness. The strength of recommendation was provided according to research evidence, clinical expertise, and perceived patient preference. RESULTS: Eleven key propositions involving 17 treatment modalities were generated through three Delphi rounds. Treatment topics included general considerations (for example, clinical features, risk factors, comorbidities), non-pharmacological (for example, education plus exercise, local heat, and splint), pharmacological (for example, paracetamol, NSAIDs, NSAIDs plus gastroprotective agents, COX-2 inhibitors, systemic slow acting disease modifying drugs, intra-articular corticosteroids), and surgery. Of 17 treatment modalities, only six were supported by research evidence (education plus exercise, NSAIDs, COX-2 inhibitors, topical NSAIDs, topical capsaicin, and chondroitin sulphate). Others were supported either by evidence extrapolated from studies of OA affecting other joint sites or by expert opinion. Strength of recommendation varied according to level of evidence, benefits and harms/costs of the treatment, and clinical expertise. CONCLUSION: Eleven key recommendations for treatment of hand OA were developed using a combination of research based evidence and expert consensus. The evidence was evaluated and the strength of recommendation was provided.

Conservative hand therapy treatments in rheumatoid arthritis--a randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of three different physiotherapeutic approaches in the management of the rheumatoid hand. METHODS: In a randomized controlled trial, participants with rheumatoid arthritis (RA) recruited from a rheumatology department in Mid-Staffordshire, UK (February 1999 to January 2001) were randomized to three groups. All received joint protection (JP) information delivered by a therapist at baseline. Group 1 participants received a set of additional hand-strengthening and mobilizing home exercises, group 2 a different set of additional hand-stretching exercises and group 3 the JP information alone. The primary outcome was the Arthritis Impact Measurement Scales II (AIMS II) (upper limb; hand and finger function subscales). Outcomes were assessed at baseline and 1, 3 and 6 months. Analysis was by intention to treat. RESULTS: Sixty-seven participants (mean age 59.6 yr) were recruited: group 1 n = 21, group 2 n = 24 and group 3 n = 22. A 78% follow-up was achieved at 6 months. There was a mean fall (SD) in AIMS II upper limb function 0-6 month change scores in group 1 of 1.00 (1.07). In groups 2 and 3 there was a mean increase in AIMS II scores of 0.18 (1.54) and 0.30 (1.22), respectively. The differences in AIMS change scores between group 1 and groups 2 and 3 were statistically significant (P = 0.007) and remained so after adjustment for multiple testing (P = 0.012). CONCLUSION: Statistically significant improvements in arm function have been demonstrated following a programme of home-strengthening hand exercises in RA patients compared with simple stretches or advice alone.

A cost consequences analysis of local corticosteroid injection and physiotherapy for the treatment of new episodes of unilateral shoulder pain in primary care.

OBJECTIVE: Local steroid injections and community-based physiotherapy have been shown to be of similar benefit for treating shoulder pain presenting to primary care. This paper presents a cost consequences analysis of a prospective economic evaluation, conducted alongside a randomized clinical trial (RCT) of corticosteroid injections versus physiotherapy for new episodes of unilateral shoulder pain, to determine the economic implications of injection versus physiotherapy. METHODS: A pragmatic RCT with 207 patients randomized to either physiotherapy (n = 103) or local steroid injection (n = 104) was conducted. The resource inputs required were identified for each treatment arm in terms of capital, staff and consumables. These were measured for the period up to 6 months post-randomization. Outcome measures included shoulder disability, shoulder pain, global assessment of health change and the EQ5D, all at 6 months. A sensitivity analysis was performed around the general practitioner minor surgical fee. RESULTS: Analysis is presented on the 199 patients for which the general practice record review (101 physiotherapy, 98 injection) was available. The total mean costs, per patient, were 71.28 pound sterling for the injection group and 114.60 pound sterling for the physiotherapy group. The difference in average total cost per patient was 43.32 pound sterling (95% bootstrap confidence interval: 16.21 pound sterling, 68.03 pound sterling ). This is a statistically significant difference in cost. Outcome was similar in both groups across all measures following intervention. Smaller mean differences in cost were observed between the treatment groups in the sensitivity analysis, but the difference remained in favour of injection over physiotherapy. CONCLUSIONS: This study has shown, given similar clinical outcomes across the treatment groups, that corticosteroid injections were the cost-effective option for patients presenting with new episodes of unilateral shoulder pain in primary care.

Two pragmatic trials of treatment for shoulder disorders in primary care: generalisability, course, and prognostic indicators.

OBJECTIVE: To investigate predictors of long term prognosis in patients treated for shoulder pain in primary care. METHODS: Data were taken from two pragmatic randomised clinical trials investigating the effectiveness of conservative treatments for shoulder pain presenting to primary care. Shoulder pain severity, disability, and perceived recovery measured in the long term (UK, 18 months; Netherlands, 12 months) were considered as outcome measures. Prognostic indicators measured before randomisation were determined by linear regression (pain severity and disability) and logistic regression (perceived recovery). RESULTS: 316 adults with a new episode of shoulder pain were recruited (UK, n = 207; Netherlands, n = 109). In multivariate analysis, greater shoulder disability at follow up was associated with higher baseline disability score, concomitant neck pain, and a gradual onset and longer duration of shoulder symptoms. Pain scores at follow up were higher in women and in those with longer baseline duration of symptoms and higher baseline pain or disability scores. Being female, reporting gradual onset of symptoms, and a higher baseline disability score each independently reduced the likelihood of perceived recovery. CONCLUSIONS: The results suggest that there is no long term difference in outcome between patients with shoulder pain treated with different clinical interventions in different clinical settings, or having different clinical diagnoses. Baseline clinical characteristics of this consulting population, rather than the randomised treatments which they received, were the most powerful predictors of outcome. Whether this highlights the need for earlier intervention or reflects different natural histories of shoulder pain is a topic for further research.

Spinal mobility in ankylosing spondylitis: reliability, validity and responsiveness.

OBJECTIVE: To evaluate the measurement properties of an evidence-based selection of measures of spinal mobility in patients with ankylosing spondylitis (AS). METHODS: Measurements of spinal mobility were taken by trained observers within a UK rheumatology centre. Inter-observer reliability was assessed. Intra-observer reliability was assessed in patients reporting no change in AS-specific health at 2 weeks. Validity was assessed and scores were correlated with responses to health transition questions. Responsiveness was evaluated for patients reporting change in health at 6 months. RESULTS: Reliability estimates support the use of all measures in individual evaluation (intraclass correlation>0.90). Correlations between measures of spinal mobility were in the hypothesized direction; the largest was between the modified Schober index (15 cm) (MSI) and the other measures. As hypothesized, small to moderate levels of correlation were found between mobility measures and patient-assessed health status. There was no significant linear relationship between mobility measures and self-reported health transition. Fingertip-to-floor distance following trunk forward flexion (FFD) was the most responsive mobility measure but was not as responsive as two AS-specific patient-assessed instruments, the Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). The MSI and cervical rotation (Crot) also had evidence of responsiveness. Low levels of responsiveness were found for the remaining measures. CONCLUSION: All mobility measures had adequate levels of reliability and validity. The MSI had a strong relationship with all mobility measures, and the FFD and Crot were the most responsive to self-perceived changes in health at 6 months. The MSI, FFD and Crot are recommended for clinical practice and research.

Describing three-dimensional cervical spine movement in a diseased and a non-diseased group using multilevel modelling.

Clinicians often request patients to perform movements of joints as an aid to assessment and diagnosis of many diseases. However, patients may perform abnormal secondary movements where their primary movement is limited. A new measuring system, the FASTRAK, has the potential to measure movement in three dimensions, and to measure movements of the body away from the primary movement. This paper explores the use of multilevel modelling to describe the patterns of movement where subjects are measured on several occasions for both a non-diseased group and for a group of subjects suffering from ankylosing spondylitis. Three-level multilevel models are described with level 3 being the subjects, level 2 being the measurement occasions (up to three) and level 1 being the measurements (three) on each occasion. The models highlight which are the most important secondary movements during the primary movement and show clinically interpretable patterns of movement that can highlight differences between diseased and non-diseased groups.

A pragmatic randomised controlled trial of local corticosteroid injection and physiotherapy for the treatment of new episodes of unilateral shoulder pain in primary care.

OBJECTIVES: To compare the long term effectiveness of local steroid injections administered by general practitioners with practice based physiotherapy for treating patients presenting in primary care with new episodes of unilateral shoulder pain. METHODS: Adults consulting with shoulder pain were recruited by their general practitioner. Patients were randomly allocated to receive either corticosteroid injections or community based physiotherapy. Primary outcome was self reported disability from shoulder problems at six months. Secondary outcomes included participant's global assessment of change; pain; function; "main complaint"; range of shoulder movement; co-interventions. A study nurse unaware of the treatment allocation performed baseline and follow up assessments. Analysis was by intention to treat. RESULTS: Over 22 months 207 participants were randomised, 103 to physiotherapy and 104 to injection. Prognostic variables were similar between the two groups at baseline. Mean (SD) improvements in disability scores at six weeks were 2.56 (5.4) for physiotherapy and 3.03 (6.3) for injection (mean difference=-0.5, 95% confidence interval (95% CI): -2.1 to 1.2) and at six months were 5.97 (5.4) for physiotherapy and 4.55 (5.9) for injection (mean difference=1.4, 95% CI -0.2 to 3.0). A "successful outcome" (a minimum 50% drop in the disability score from baseline) at six months was achieved by 59/99 (60%) in the physiotherapy group and 51/97 (53%) in the injection group (percentage difference=7%, 95% CI -6.8% to 20.4%). Co-interventions were more common in the injection group during follow up. CONCLUSION: Community physiotherapy and local steroid injections were of similar effectiveness for treating new episodes of unilateral shoulder pain in primary care, but those receiving physiotherapy had fewer co-interventions.

Disease-specific, patient-assessed measures of health outcome in ankylosing spondylitis: reliability, validity and responsiveness.

OBJECTIVE: To assess the acceptability and measurement properties of four ankylosing spondylitis (AS)-specific, patient-assessed measures of health outcome: AS Quality of Life Questionnaire (ASQoL), Bath AS Disease Activity Index (BASDAI), the Body Chart and the Revised Leeds Disability Questionnaire (RLDQ). METHODS: Instruments were administered by means of a self-completed questionnaire to patients recruited from across the United Kingdom (UK). Instruments were assessed for data quality and scaling assumptions. Where appropriate, dimensionality was assessed using principle component analysis (PCA). Internal consistency reliability was tested using Cronbach's alpha. Test-retest reliability was assessed in those patients reporting no change in AS-specific health at 2 weeks. The convergent validity of the instruments was assessed and scores were correlated with responses to the health transition questions. Responsiveness was assessed for patients reporting change in health at 6 months. RESULTS: The BASDAI and Body Chart have low self-completion rates. Item responses for the RLDQ were skewed towards higher levels of functional ability. PCA supported instrument unidimensionality. Cronbach's alpha ranged from 0.87 (BASDAI) to 0.93 (RLDQ). Test-retest reliability estimates support the use of the ASQoL and RLDQ in individual evaluation (>0.90). Correlations between instruments were in the hypothesized direction; the largest was between the ASQoL and BASDAI (0.79). The BASDAI had the strongest linear relationship, with responses to both specific and general health transition questions (P<0.01). With the exception of the Body Chart, instruments had a stronger relationship with general health transition. The BASDAI was the most responsive instrument. The Body Chart and RLDQ had low levels of responsiveness. CONCLUSION: The instruments have undergone a comprehensive comparative evaluation to assess the measurement properties required for patient-assessed measures of health outcome. Adequate levels of reliability and validity were found for all instruments. The BASDAI and the ASQoL were the most responsive to self-perceived change in health, but the BASDAI had low levels of self-completion.

Generic measures of health-related quality of life in ankylosing spondylitis: reliability, validity and responsiveness.

OBJECTIVE: To assess the acceptability and measurement properties of two generic measures of health-related quality of life (HRQL): the EuroQol and the Short Form 12-item Health Survey Questionnaire (SF-12) in ankylosing spondylitis (AS). METHODS: Instruments were administered by means of a self-completed questionnaire to AS patients recruited from across the United Kingdom. Instruments were assessed for data quality and scaling assumptions. Test-retest reliability was assessed in those patients reporting no change in general health at 2 weeks. The convergent validity of both instruments was assessed and scores were correlated with responses to health transition questions. Responsiveness was assessed for patients reporting change in health at 6 months. RESULTS: The instruments had high completion rates. Although slightly skewed towards better levels of health, scores covered the available range for both sections of the EuroQol [EQ-5D and EQ-visual analogue scale (EQ-VAS)]. Score distributions approximated normality for the SF-12. Test-retest reliability estimates support the use of both instruments in group evaluation and the SF-12 Physical Component Summary score (PCS) in individual evaluation (>0.90). Correlations between instruments were in the hypothesized direction and were of a moderate level. The EQ-VAS had the strongest linear relationship, with responses to both specific and general health transition questions (P<0.01). The EQ-VAS and SF-12 PCS were the most responsive instruments. The EQ-5D was the least responsive instrument. CONCLUSION: The instruments have undergone a comprehensive comparative evaluation to assess the measurement properties required for patient-assessed measures of health outcome in AS. Adequate levels of acceptability, reliability and validity were found for both instruments. Although evidence supporting instrument responsiveness was strong for the EQ-VAS and SF-12 PCS, it was very weak for the EQ-5D and SF-12 Mental Component Summary Scale (MCS). The EQ-VAS and SF-12 PCS can both be recommended for use in group evaluation, and the SF-12 PCS is recommended in routine practice or research. However, the lower reliability of the SF-12 MCS and the limited ability of both the EQ-5D and SF-12 MCS to detect change in health may restrict these roles.

The reliability of the three-dimensional FASTRAK measurement system in measuring cervical spine and shoulder range of motion in healthy subjects.

OBJECTIVES: To assess the inter-observer and intra-observer reliability of a new three-dimensional measurement system, the FASTRAK, in measuring cervical spine flexion/extension, lateral flexion and rotation and shoulder flexion/extension, abduction and external rotation in healthy subjects. METHODS: The study was conducted in two parts. One part assessed inter-observer reliability with two observers measuring 40 subjects. The other part assessed intra-observer reliability with one observer measuring 32 subjects on three occasions. All subjects had unrestricted, pain-free cervical spine and shoulder movement. Reliability was measured by the intraclass correlation coefficient [ICC(2,1)]. RESULTS: The inter-observer ICCs for the cervical spine ranged from 0.61 to 0.89 and for the shoulder from 0.68 to 0.75. After removal of outliers, all ICCs were above 0.70. Intra-observer ICCs for the cervical spine ranged from 0.54 to 0.82 and for the shoulder from 0.62 to 0.81. After removal of outliers, all ICCs were above 0.70 except for shoulder abduction (0.62). CONCLUSIONS: Whilst all movements measured by the FASTRAK showed good reliability, the reliability of the whole movement in a plane (e.g. left plus right lateral flexion) was better than for the separate movements (e.g. left and right lateral flexion taken separately). Inter-observer reliability was generally better than intra-observer reliability for most cervical spine movements, suggesting that variability of movement within subjects (e.g. over a period of days) for these movements was greater than variability between measures on the same occasion.

Treatment options for regional musculoskeletal pain: what is the evidence?

Decisions about the best treatment options for patients with regional musculoskeletal pain must be made despite a lack of clear diagnostic criteria, an absence of robust outcome measures by which to assess response, and a paucity of evidence from high-quality randomized controlled trials. Although the randomized controlled trial is considered to be the 'gold standard' research design, it does not lend itself easily to the evaluation of all management strategies. This chapter explores these issues from a research perspective and reviews the various types of evidence available to help practitioners make informed decisions. The current evidence from systematic reviews in this area is summarized in the final part of the chapter.

[Pneumothorax in cigarette smokers].

From 1.01.1992 to 31.12.1998 ill prisoners were treated because of so called spontaneous pneumothorax. Their age was between 24 to 57, which was 33 in average. All of them were males and heavy smokers. In one case of the coat pneumothorax the treatment was limited only to the breathing exercises, to ten other patients an under-water-seal drainage was applied, in the next case with pneumothorax and clear symptoms of bronchial fistula, the lung expansion was obtained no sooner than after the usage of a suction drainage. The risk of recurrence of the illness was limited by injection of 40% glucose solution through the drain to the pleural cavity to increase adhesions.

Radiographic patterns and response to corticosteroid hip injection.

OBJECTIVES: A prospective, open study of corticosteroid hip injection (CHI) was performed to determine if different radiological patterns of arthritis vary in their response. METHODS: Forty five patients (15 with rheumatoid arthritis, 27 with osteoarthritis, and three with anklyosing spondylitis) underwent hip injection with 80 mg methylprednisolone and lignocaine under x ray control. Outcome was assessed at two, 12, and 26 weeks for pain, range of hip movement, and graded functional questionnaire. Patients estimated their pain in four components, night pain, rest pain, weight bearing, and referred pain, each measured by 10 cm visual analogue score and summed to give a total score out of 40 cm. Hip radiographs were evaluated blindly for pattern and severity of arthritis, as well as for progression between 0 and 26 weeks. RESULTS: Median total pain score decreased from 29 cm at baseline to 22 cm at two weeks (p = 0.0001), 24 cm at 12 weeks (p = 0.03), but had returned nearly to baseline by 26 weeks (25 cm, p = 0.3). Greatest improvement was seen for night pain. Mean range of internal rotation increased from 16 to 28 degrees at two weeks (p = 0.03) and 21 degrees at 12 weeks (p = 0.06). Functional ability did not change. Hips with an atrophic pattern of arthritis on plain radiography gained negligible pain relief at two weeks compared with hips with a hypertrophic or mixed bone response (p = 0.04). The degree of pain relief was similar in patients with OA and RA, and was not influenced by radiographic severity or by the direction of migration of the femoral head. CONCLUSION: Pain and internal rotation improve for up to 12 weeks after CHI. CHI offers a useful and safe therapeutic option for patients with hip arthritis, with the exception of those with a purely atrophic radiological pattern.
