Attitudes toward management of patients with subacromial pain in Swedish primary care

Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment

ABSTRACT

We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). Coprimary outcomes were self-reported reassurance that no serious condition is causing their pain and continuing with daily activities is safe. Secondary outcomes measured management intentions, credibility and relevance of the education, and similarity to previous education. Two thousand two hundred thirty-seven participants were randomised and provided primary outcome data. Best practice education increased reassurance that no serious condition is causing their pain (estimated mean effect 0.5 on a 0-10 scale, 95% confidence interval [CI] 0.2-0.7) and continuing with daily activities is safe (0.6, 95% CI 0.3-0.8) compared with structure-focused education . Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.

How do people perceive different advice for rotator cuff disease? A content analysis of qualitative data collected in a randomised experiment

OBJECTIVES

To explore how people perceive different advice for rotator cuff disease in terms of words/feelings evoked by the advice and treatment needs.

SETTING

We performed a content analysis of qualitative data collected in a randomised experiment.

PARTICIPANTS

2028 people with shoulder pain read a vignette describing someone with rotator cuff disease and were randomised to: bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation emphasised that treatment is needed for recovery.

PRIMARY AND SECONDARY OUTCOMES

Participants answered questions about: (1) words/feelings evoked by the advice; (2) treatments they feel are needed. Two researchers developed coding frameworks to analyse responses.

RESULTS

1981 (97% of 2039 randomised) responses for each question were analysed. Guideline-based advice (vs treatment recommendation) more often elicited words/feelings of reassurance, having a minor issue, trust in expertise and feeling dismissed, and treatment needs of rest, activity modification, medication, wait and see, exercise and normal movements. Treatment recommendation (vs guideline-based advice) more often elicited words/feelings of needing treatment/investigation, psychological distress and having a serious issue, and treatment needs of injections, surgery, investigations, and to see a doctor.

CONCLUSIONS

Words/feelings evoked by advice for rotator cuff disease and perceived treatment needs may explain why guideline-based advice reduces perceived need for unnecessary care compared to a treatment recommendation.

Diagnostic labels and advice for rotator cuff disease influence perceived need for shoulder surgery: an online randomised experiment

QUESTION

What are the effects of diagnostic labels and advice, and interactions between labels and advice, on perceived need for shoulder surgery for rotator cuff disease?

DESIGN

2×2 factorial online randomised experiment.

PARTICIPANTS

People with shoulder pain.

INTERVENTION

Participants read a scenario describing a patient with rotator cuff disease and were randomised to bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice, and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation stressed that treatment is needed for recovery.

OUTCOME MEASURES

Perceived need for surgery (primary outcome), imaging, an injection, a second opinion and to see a specialist; and perceived seriousness of the condition, recovery expectations, impact on work performance and need to avoid work.

RESULTS

A total of 2,024 responses (99.8% of 2,028 randomised) were analysed. Labelling as bursitis (versus rotator cuff tear) decreased perceived need for surgery (mean effect -0.5 on a 0-to-10 scale, 98.3% CI -0.7 to -0.2), imaging and to see a specialist, and perceived seriousness of the condition and need to avoid work. Guideline-based advice (versus treatment recommendation) decreased perceived need for surgery (mean effect -1.0, 98.3% CI -1.3 to -0.7), imaging, an injection, a second opinion and to see a specialist, and perceived seriousness of the condition and recovery expectations. There was little to no evidence of an advice label interaction for any outcome.

CONCLUSION

Labels and advice influenced perceived need for surgery and other secondary outcomes in people with rotator cuff disease, with larger effects for advice. There was evidence of little or no interaction between labels and advice for any outcome, but the additive effect of labels and advice appeared large for some outcomes (eg, perceived need for imaging and perceived seriousness of the condition).

Do physical therapists follow evidence-based guidelines when managing musculoskeletal conditions? Systematic review

OBJECTIVES

Physicians often refer patients with musculoskeletal conditions to physical therapy. However, it is unclear to what extent physical therapists' treatment choices align with the evidence. The aim of this systematic review was to determine what percentage of physical therapy treatment choices for musculoskeletal conditions agree with management recommendations in evidence-based guidelines and systematic reviews.

DESIGN

Systematic review.

SETTING

We performed searches in Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, Allied and Complementary Medicine, Scopus and Web of Science combining terms synonymous with 'practice patterns' and 'physical therapy' from the earliest record to April 2018.

PARTICIPANTS

Studies that quantified physical therapy treatment choices for musculoskeletal conditions through surveys of physical therapists, audits of clinical notes and other methods (eg, audits of billing codes, clinical observation) were eligible for inclusion.

PRIMARY AND SECONDARY OUTCOMES

Using medians and IQRs, we summarised the percentage of physical therapists who chose treatments that were recommended, not recommended and had no recommendation, and summarised the percentage of physical therapy treatments provided for various musculoskeletal conditions within the categories of recommended, not recommended and no recommendation. Results were stratified by condition and how treatment choices were assessed (surveys of physical therapists vs audits of clinical notes).

RESULTS

We included 94 studies. For musculoskeletal conditions, the median percentage of physical therapists who chose recommended treatments was 54% (n=23 studies; surveys completed by physical therapists) and the median percentage of patients that received recommended physical therapy-delivered treatments was 63% (n=8 studies; audits of clinical notes). For treatments not recommended, these percentages were 43% (n=37; surveys) and 27% (n=20; audits). For treatments with no recommendation, these percentages were 81% (n=37; surveys) and 45% (n=31; audits).

CONCLUSIONS

Many physical therapists seem not to follow evidence-based guidelines when managing musculoskeletal conditions. There is considerable scope to increase use of recommended treatments and reduce use of treatments that are not recommended.

Physical Therapists' Perceptions and Use of Exercise in the Management of Subacromial Shoulder Impingement Syndrome: Focus Group Study

BACKGROUND

Shoulder pain resulting from subacromial impingement syndrome (SAIS) is a common problem with a relatively poor response to treatment. There is little research exploring physical therapists' perspectives on the management of the syndrome.

OBJECTIVES

The study objective was to investigate physical therapists' perceptions and experiences regarding the use of exercise in the treatment of patients with SAIS.

DESIGN

This was a qualitative focus group study.

METHODS

Three 60- to 90-minute focus group sessions containing 6 to 8 experienced musculoskeletal physical therapists (total number=20) were conducted. Thematic content analysis was used to analyze transcripts and develop core themes and categories.

RESULTS

Exercise was seen as key in the management of SAIS. The overarching theme was the need to "gain buy-in to exercise" at an early stage. The main subtheme was patient education. Therapists identified the need to use education about SAIS etiology to foster buy-in and "sell" self-management through exercise to the patient. They consistently mentioned achieving education and buy-in using visual tools, postural advice, and sometimes a "quick fix" of pain control. Furthermore, experienced practitioners reported including educational interventions much earlier in treatment than when they first qualified. Therapists emphasized the need for individually tailored exercises, including: scapular stabilization; rotator cuff, lower trapezius, and serratus anterior muscle strengthening; and anterior shoulder and pectoralis minor muscle stretching. Quality of exercise performance was deemed more important than the number of repetitions that the patients performed.

LIMITATIONS

Expanding the geographical area over which the focus groups were conducted and including therapists with less than 5 years of postgraduate experience may have strengthened the findings of this study.

CONCLUSION

Experienced musculoskeletal physical therapists believe that exercise is central in treating patients with SAIS and that gaining patient buy-in to its importance, patient education, promoting self-management, and postural advice are central to the successful treatment of people with SAIS.

Clinical practice in line with evidence? A survey among primary care physiotherapists in western Sweden

RATIONALE, AIMS AND OBJECTIVES

Evidence-based practice is becoming increasingly important in primary care physiotherapy. Clinical practice needs to reflect current best evidence and be concordant with evidence-based clinical guidelines. There is limited knowledge about therapeutic interventions used in primary care physiotherapy in Sweden. The objectives were to examine preferred treatment interventions reported by publicly employed physiotherapists in primary care for three common musculoskeletal disorders (low back pain, neck pain and subacromial pain), the extent to which these interventions were supported by evidence, and associations with demographic variables.

METHODS

419 physiotherapists in primary care in western Sweden were surveyed using a validated web-based questionnaire.

RESULTS

The survey was completed by 271 respondents (65%). Median number of interventions reported was 7 (range 1-16). The most common treatment interventions across the three conditions were advice on posture (reported by 82-94%), advice to stay active (86-92%), and different types of exercise (65-92%). Most of these interventions were supported by evidence. However, interventions with insufficient evidence, such as advice on posture, TENS and aquatic exercise, were also used by 29-96%. Modalities such as laser therapy and ultrasound were sparingly used (<5%), which is in line with evidence. For neck pain, use of evidence-based interventions was associated with gender and for subacromial pain, with work experience.

CONCLUSIONS

Advice and exercise therapy were the interventions most frequently reported across the three diagnoses, illustrating an active treatment strategy. While most reported interventions are supported by evidence, interventions with unclear or no evidence of effect were also used to a high extent.

The use of evidence-based practices for the management of shoulder impingement syndrome among Indian physical therapists: a cross-sectional survey

Background:

The understanding of the pathomechanics of shoulder impingement has evolved over the years. Likewise, assessment techniques and effective treatment strategies have also been developed. Physical therapists should keep up-to-date on the current evidence.

Objective:

This study explored the practices currently used by Indian physical therapists for the assessment and management of shoulder impingement syndrome (SIS).

Method:

Using an online questionnaire, therapists were asked to declare the causes, methods of assessment and their choices of physical therapy techniques for the management of SIS. The proportions of therapists using different techniques were analyzed descriptively, and comparisons across gender, experience level, and training were made. Data were analyzed to see if the choices of respondents compared with their responses for etiology.

Results:

A total of 211 responses were analyzed. Most respondents (>75%) believed that overuse and abnormal motion/posture are the most significant causes of SIS. However, fewer respondents reported assessing posture (60.2%) and dyskinesis, especially in women (24.2%). Ninety-four percent of the respondents reported using exercises, but exercise prescription was rather generic. Therapists additionally trained in the techniques of joint mobilization or taping declared using these techniques more frequently. The use of interferential therapy and ultrasound was reported by 89.5% and 98.4% of respondents, respectively

Conclusion:

Most therapists declared awareness of current recommended practices, but patient assessment, exercise prescription, and use of electrotherapy modalities were only partially based on current evidence. The study helps to identify gaps in current physical therapy approaches to SIS in India.

Low-level laser therapy in IL-1β, COX-2, and PGE2 modulation in partially injured Achilles tendon

This study evaluated IL-1β, COX-2, and PGE2 modulation in partially injured Achilles tendons treated with low-level laser therapy (LLLT). Sixty-five male Wistar rats were used. Sixty were submitted to a direct injury on Achilles tendon and then distributed into six groups: LASER 1 (a single LLLT application), LASER 3 (three LLLT applications), and LASER 7 (seven LLLT applications) and Sham 1, 3, and 7 (the same injury but LLLT applications were simulated). The five remaining animals were allocated at control group (no procedure performed). LLLT (780 nm) was applied with 70 mW of mean power and 17.5 J/cm(2) of fluency for 10 s, once a day. The tendons were surgically removed and assessed immunohistochemically for IL-1β, COX-2, and PGE2. In comparisons with control (IL-1β: 100.5 ± 92.5 / COX-2: 180.1 ± 97.1 / PGE2: 187.8 ± 128.8) IL-1β exhibited (mean ± SD) near-normal level (p > 0.05) at LASER 3 (142.0 ± 162.4). COX-2 and PGE2 exhibited near-normal levels (p > 0.05) at LASER 3 (COX-2: 176.9 ± 75.4 / PGE2: 297.2 ± 259.6) and LASER 7 (COX-2: 259.2 ± 190.4 / PGE2: 587.1 ± 409.7). LLLT decreased Achilles tendon's inflammatory process.

Infrared (810 nm) low-level laser therapy in rat achilles tendinitis: a consistent alternative to drugs

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used and can reduce musculoskeletal pain in spite of the cost of adverse reactions like gastrointestinal ulcers or cardiovascular events. The current study investigates if a safer treatment such as low-level laser therapy (LLLT) could reduce tendinitis inflammation, and whether a possible pathway could be through inhibition of either of the two-cyclooxygenase (COX) isoforms in inflammation. Wistar rats (six animals per group) were injected with saline (control) or collagenase in their Achilles tendons. Then, we treated them with three different doses of IR LLLT (810 nm; 100 mW; 10 s, 30 s and 60 s; 3.57 W cm(-2); 1 J, 3 J, 6 J) at the sites of the injections, or intramuscular diclofenac, a nonselective COX inhibitor/NSAID. We found that LLLT dose of 3 J significantly reduced inflammation through less COX-2-derived gene expression and PGE(2) production, and less edema formation compared to nonirradiated controls. Diclofenac controls exhibited significantly lower PGE(2) cytokine levels at 6 h than collagenase control, but COX isoform 1-derived gene expression and cytokine PGE(2) levels were not affected by treatments. As LLLT seems to act on inflammation through a selective inhibition of the COX-2 isoform in collagenase-induced tendinitis, LLLT may have potential to become a new and safer nondrug alternative to coxibs.

Subacromial corticosteroid injection or acupuncture with home exercises when treating patients with subacromial impingement in primary care--a randomized clinical trial

BACKGROUND

Patients with subacromial impingement syndrome (SIS) commonly seek primary care. Subacromial corticosteroid injection is the standard treatment given by GPs, which is supported by earlier studies reporting a positive effect but inconclusive evidence over the long- term. In Sweden, physiotherapists often choose acupuncture combined with exercises to treat SIS, which was reported as probably efficacious.

OBJECTIVE

To compare the efficacy of subacromial corticosteroids injected by a GP with physiotherapy combining acupuncture and home exercises as treatments for SIS.

METHODS

A randomized clinical trial was performed in primary health care. Patients diagnosed with SIS were randomized to either subacromial corticosteroid injection(s) or 10 acupuncture treatments combined with home- exercises. The main outcomes were pain and shoulder function (Adolfsson-Lysholm shoulder assessment score). Secondary outcomes were health-related quality of life (HRQL) (EuroQol-five dimension self-report questionnaire) and the patients' global assessment of change. All patients were assessed at baseline and after 6 weeks and 3, 6 and 12 months.

RESULTS

One hundred and seventeen patients with SIS were included, of which 91 complied with the study protocol. There were no significant differences between treatments with regard to pain, shoulder function and HRQL in change over time. However, both treatment groups improved significantly from baseline over time.

CONCLUSIONS

Both subacromial corticosteroid injection and a series of acupuncture treatments combined with home exercises significantly decreased pain and improved shoulder function in patients with SIS, but neither treatment was significantly superior to the other.

A randomised, placebo controlled trial of low level laser therapy for activated Achilles tendinitis with microdialysis measurement of peritendinous prostaglandin E2 concentrations

BACKGROUND

Low level laser therapy (LLLT) has gained increasing popularity in the management of tendinopathy and arthritis. Results from in vitro and in vivo studies have suggested that inflammatory modulation is one of several possible biological mechanisms of LLLT action.

OBJECTIVE

To investigate in situ if LLLT has an anti-inflammatory effect on activated tendinitis of the human Achilles tendon.

SUBJECTS

Seven patients with bilateral Achilles tendinitis (14 tendons) who had aggravated symptoms produced by pain inducing activity immediately before the study.

METHOD

Infrared (904 nm wavelength) LLLT (5.4 J per point, power density 20 mW/cm2) and placebo LLLT (0 J) were administered to both Achilles tendons in random blinded order.

RESULTS

Ultrasonography Doppler measurements at baseline showed minor inflammation through increased intratendinous blood flow in all 14 tendons and measurable resistive index in eight tendons of 0.91 (95% confidence interval 0.87 to 0.95). Prostaglandin E2 concentrations were significantly reduced 75, 90, and 105 minutes after active LLLT compared with concentrations before treatment (p = 0.026) and after placebo LLLT (p = 0.009). Pressure pain threshold had increased significantly (p = 0.012) after active LLLT compared with placebo LLLT: the mean difference in the change between the groups was 0.40 kg/cm2 (95% confidence interval 0.10 to 0.70).

CONCLUSION

LLLT at a dose of 5.4 J per point can reduce inflammation and pain in activated Achilles tendinitis. LLLT may therefore have potential in the management of diseases with an inflammatory component.

Celecoxib is as efficacious as naproxen in the management of acute shoulder pain

This study compared the analgesic efficacy and safety of the cyclo-oxygenase-2 specific inhibitor celecoxib with the non-specific non-steroidal anti-inflammatory drug, naproxen, in patients with acute shoulder pain. Adult patients with shoulder pain, onset within the previous 14 days and shoulder pain of > or = 40 mm on a 100 mm visual analogue scale (VAS), were treated with oral doses of celecoxib or naproxen for 14 days and followed by a visit at day 42 in a double-blind, randomized study. The primary efficacy assessment was change in maximum pain at rest on a 100 mm VAS at day 14 compared with baseline. In addition, secondary efficacy pain and functional assessments were analysed at baseline, day 14 and day 42. A total of 202 patients were included in the trial (99 celecoxib 400 mg/day; 103 naproxen 1 g/day). The difference in change from baseline at day 14 in maximum pain at rest was not statistically significant between the two treatment groups, but was numerically higher for celecoxib than for naproxen (-47.9 +/- 2.5 versus -42.3 +/- 2.5, respectively). According to the limits of the 95% confidence interval of the difference between groups (-12.52; 1.38), celecoxib appeared to be at least as effective as naproxen. All secondary efficacy measures followed the same pattern, showing similarity between the two treatments with a trend in favour of celecoxib. The incidences of adverse events were similar for both groups. Fewer patients experienced epigastric pain with celecoxib (seven patients versus 14 with naproxen). This adverse event led to discontinuation in two patients receiving celecoxib and five receiving naproxen. Celecoxib 400 mg/day was at least as effective as naproxen 1 g/day in managing pain in this condition.
