Exploring the personal burden of shoulder pain among younger people in Australia: protocol for a multicentre cohort study

Radiofrequency of suprascapular nerve as an analgesic strategy for chronic pain management. Systematic review and meta-analysis

INTRODUCTION

Chronic shoulder pain is highly prevalent in the general population. Many different analgesic strategies have been described, including radiofrequency treatment to the suprascapular nerve (RFS); however, the effectiveness this approach remains unclear, and no strong recommendation can be made. The aim of this systematic review is to analyse the latest clinical trials evaluating the effectiveness of RFS techniques applied to the suprascapular nerve in terms of management of chronic shoulder pain, post-procedural functionality, and adverse effects.

METHODS

We performed a systematic review of clinical trials retrieved from Medline, Embase and the CENTRAL databases. We included trials comparing RFS with other strategies, including placebo, that had as their primary outcome measures pain rated on a visual analogue scale, functionality rated on a shoulder pain and disability index (SPADI), and the incidence of adverse events. Risk of bias was analysed using the Cochrane RoB2 tool. Evidence was analysed using a random effects model and heterogeneity was quantified using the I2 test.

RESULTS

We identified 3030 trials, of which 8 met the inclusion criteria (n = 408). Seven had a high risk of bias. Pain intensity at 1 and 3 months was lower in patients receiving RFS, with a standardised mean difference (SMD) of -0.9 (95% CI [-1.1, 0.33], p = 0.29; I2 88%, p < 0.001) and -1.17 (95% CI [-2.49, 0.14], p = 0.08; I2 97%, p < 0.001), respectively. Functional compromise at 1 and 3 months decreased in patients receiving RFS, with an SMD of -0.31 (95% CI [-0.91, 0.29], p = 0.31; I2 80%, p < 0.001) and -1.54 (95% CI [-3.26, 0.19], p = 0.08; I2 98%, p < 0.001), respectively. No RFS-related adverse events were described.

CONCLUSION

The evidence suggests that RFS reduces pain and improves functionality. However, the certainty of the evidence is low.

Efficacy of hypertonic dextrose proliferation therapy in the treatment of rotator cuff lesions: a meta-analysis

BACKGROUND

One of the most prevalent illnesses of the shoulder is rotator cuff tendinosis, which is also a major contributor to shoulder discomfort and shoulder joint dysfunction. According to statistics, rotator cuff tendinosis occurs in 0.3-5.5% of cases and affects 0.5-7.4% of people annually. It will be necessary to conduct a meta-analysis to evaluate the efficacy of hypertonic glucose proliferation therapy in the treatment of rotator cuff problems.

METHODS

The databases Cochrane PubMed, Library, Web of Science and EMbase, are retrieved by the computer. Individuals with rotator cuff lesions in the intervention group were treated with hypertonic dextrose proliferation therapy, whereas individuals in the control condition were treated with a placebo. Outcome markers for rotator cuff lesions patients; Pursuant to studies, the visual analogue scale (VAS) score, the shoulder pain & disability index (SPADI), & other metrics are used to evaluate the effects of hypertonic dextrose proliferation treatment on individuals with rotator cuff diseases. After carefully evaluating the calibre of the literature, data analysis was performed utilising the RevMan 5.3 programme.

RESULTS

Meta-analysis finally contained 6 papers. In six investigations, the test & control group's VAS scores improved, with the test team's score considerably outperforming the control team [standardized mean difference (SMD): 1.10; 95% Cl: 0.37,1.83; P < 0.01], shoulder pain and disability index (SPADI) score (SMD:8.13; 95% Cl: 5.34,10.91; P < 0.01), Flexion (SMD:5.73; 95% Cl: 0.99,10.47; P < 0.05), Abduction (SMD:6.49; 95% Cl: 0.66,12.31; P < 0.05), Internal rotation (SMD:-1.74; 95% Cl: -4.25,0.78; P = 0.176) and External rotation (SMD:2.78; 95% Cl: -0.13,5.69; P = 0.062).

CONCLUSION

The findings of this study suggest that individuals with rotator cuff injuries may benefit from hypertonic dextrose proliferation treatment based on the visual analogue scale (VAS) score, the Shoulder Pain and Disability Index (SPADI) score, Flexion, & Abduction. These results must, nevertheless, be supported by high-caliber follow-up research.

Variability in the distance between the suprascapular notch with the spine of the scapulae and the acromion

INTRODUCTION

The suprascapular notch lies in the superior border of the scapula and is a passageway for the suprascapular nerve that is sensory to the shoulder joint. Suprascapular nerve block involves injection of local anaesthetic into the suprascapular notch, either ultrasound guided or blind, using the spine of scapula and/or the medial border of the acromion as surface landmarks.

AIM

To investigate the anatomic variations that exist between the distance of the notch from the spine of scapula and acromion.

METHOD

Ninety-two dry scapulae were measured with a digital calliper for their length of the spine, distance between the midpoint of the spine and base of the suprascapular notch and distance between the medial border of the acromion and the base of the suprascapular notch. These measurements were compared for variations in the scapular bony landmarks, the spine and the acromion to determine the site for the injection.

RESULTS

Measurement reliability was assessed by intraclass correlation, Cronbach's alpha being 0.99, 0.97 and 0.91 for length of spine, distance from spine and distance from acromion respectively. The distance from the acromion had less variation in measurement (3.73 ± 0.42 cm) but a flatter distribution when compared to distance from the spine of the scapula (3.32 ± 0.39 cm).

CONCLUSION

Length of the spine of the scapula appeared not to influence either distance from the acromion or distance from the spine of scapula. There is potential for greater variability in placement of nerve blocks that use acromion as the bony reference. Key Points • Dry scapular measurement using electronic Vernier callipers is accurate (0.91-0.97). • There is potential for greater variability in placement of blind nerve blocks that use acromion as the bony reference to locate the suprascapular notch.

Managing shoulder pain: a meta-ethnography exploring healthcare providers' experiences

OBJECTIVE

To review and synthesize qualitative research studies exploring the experiences of Healthcare Providers (HCPs) of managing shoulder pain.

METHODS

A meta-ethnographic approach was adopted to review and synthesize eligible studies. The findings from each included study were translated into one another using Noblit and Hares' seven-stage process. A systematic search of eleven electronic databases was conducted in February 2021. Methodological quality was assessed using the CASP Appraisal Tool.

RESULTS

Ten studies were included in the meta-synthesis, all deemed of high methodological quality. Three themes were identified; (1) Lack of consensus: "we all have different approaches." (2) Challenges to Changing Practice: It's "really hard to change and switch to a different approach," (3) Getting "Buy in" to Treatment: "…so you have to really sell it early".

CONCLUSION

Healthcare providers working with people with shoulder pain struggle to reconcile, often conflicting, research recommendations with their own clinical experience, beliefs and patient expectations. These findings help explain the continued lack of consensus on how best to manage shoulder pain in clinical practice.IMPLICATIONS FOR REHABILITATIONHealthcare providers (HCPs) working with people with shoulder pain struggle to resolve conflicts between evidence-based recommendations, clinical experience, their own shoulder pain beliefs and patient expectations and preferences.Stronger collaboration across professional disciplines is needed to address the current lack of consensus on the management of shoulder pain.Many HCP's find it difficult to engage patients with shoulder pain in exercise and they work hard to "sell" this approach to patients using strategies such as education, shared decision making and therapeutic alliance.

ABCB1 and OPRM1 single-nucleotide polymorphisms collectively modulate chronic shoulder pain and dysfunction in South African breast cancer survivors

Background: Chronic shoulder pain/disability is a well-recognized side effect of treatment for breast cancer, with ∼40% of patients experiencing this, despite receiving pain management. To manage acute and chronic pain, several opioids are commonly prescribed. Pharmacogenomics have implicated genes within the opioid signaling pathway, including ABCB1 and OPRM1, to contribute to an individual's variable response to opioids. Aim: To evaluate ABCB1 (rs1045642 G>A, rs1128503 G>A) and OPRM1 (rs1799971 A>G, rs540825 T>A) single-nucleotide polymorphisms (SNPs) in chronic shoulder pain/disability in BCS. Materials & methods: TaqMan^TM assays were used to genotype ABCB1 and OPRM1 SNPs within the BCS (N = 252) cohort. The Shoulder Pain and Disability Index was used to evaluate pain and disability features associated with shoulder pathologies. Participants end scores for each feature (pain, disability and combined [pain and disability]) were categorized into no-low (>30%) and moderate-high (≥30%) scores. Statistical analysis was applied, and significance was accepted at p < 0.05. Results: Of participants, 27.0, 19.0 and 22.0% reported moderate-high pain, disability and combined (pain and disability) scores, respectively. ABCB1:rs1045642-(A/A) genotype was significantly associated with disability (p = 0.028: no-low [14.9%] vs mod-high [4.3%]) and combined (pain and disability) (p = 0.011: no-low [15.9%] vs mod-high [5.7%]). The ABCB1:rs1045642-(A) allele was significantly associated with disability (p = 0.015: no-low [37.9%] vs mod-high [23.9%]) and combined (pain and disability) (p = 0.003: no-low [38.5%] vs mod-high [23.6%]). The inferred ABCB1 (rs1045642 G>A - rs1128503 G>A): A-G (p = 0.029; odds ratio [OR]: 0.0; 95% CI: 0.0-0.0) and the OPRM1 (rs1799971 A>G - rs540825 T>A): G-T (p = 0.019; OR: 0.33; 95% CI: 0.14-0.75) haplotypes were associated with disability and pain, respectively. Gene-gene interactions showed the ABCB1 (rs1045642 G>A) - OPRM1 (rs540825 T>A) combinations, (A-T) (p = 0.019; OR: 0.62; 95% CI: 0.33-1.16) and (G-A) (p = 0.021; OR: 1.57; 95% CI: 0.30-3.10) were associated with disability. Conclusion: The study implicated ABCB1 with shoulder pain and disability; and haplotype analyses identified specific genetic intervals within ABCB1 and OPRM1 to associate with chronic shoulder pain and disability. Evidence suggests that potentially gene-gene interactions between ABCB1 and OPRM1 contribute to chronic shoulder pain and disability experienced in this SA cohort.

Thermotherapy for shoulder pain: A protocol for systematic review

BACKGROUND

Shoulder pain is a common musculoskeletal disorder prompting many patients to seek treatment. Thermotherapy is a common treatment for shoulder which has been widely used in hospitals. But its efficiency has not been scientifically and methodically evaluated. This protocol aims to evaluate the efficacy and safety of thermotherapy for treating shoulder pain.

METHODS

Eight databases will be searched from their inception to October 2021. They are as follows: PubMed, Embase, Cochrane Library, ClinicalTrials.gov, China Knowledge Resource Integrated Database (CNKI), Weipu Database for Chinese Technical Periodicals (VIP), Chinese Biomedical Literature Database (CBM), and Wanfang Database. Two researchers will independently select studies, collect data, and assess the methodology quality by the Cochrane risk of bias tool.

RESULTS

The systematic review will provide high-quality evidence to assess the efficacy and safety of thermotherapy for shoulder pain as well as adverse events.

CONCLUSION

The systematic review will provide evidence to assess the effectiveness and safety of thermotherapy therapy for shoulder pain patients.

Understanding Shoulder Pain: A Qualitative Evidence Synthesis Exploring the Patient Experience

OBJECTIVE

The objective of this study was to review and synthesize qualitative research studies exploring the experiences of individuals living with shoulder pain to enhance understanding of the experiences of these individuals as well as facilitate health care developments.

METHODS

A meta-ethnographic approach was adopted to review and synthesize eligible published qualitative research studies. The findings from each included study were translated into one another using the Noblit and Hares 7-stage process. A systematic search of 11 electronic databases was conducted in March 2020. Methodological quality was assessed using the Critical Appraisal Skills Programme appraisal tool.

RESULTS

Nineteen studies were included in the meta-synthesis. Included articles explored the lived experiences as well as treatment-related experiences of participants. All of the included articles were deemed to be of high methodological quality. Three themes were identified: (1) negative emotional, social, and activity impact ("It has been a big upheaval"); (2) developing an understanding ("Why is it hurting so much?"); and (3) exercise ("Am I going to go through a lot of pain in moving it…?"). Across the included studies, the severe emotional and physical impact of shoulder pain was a core finding. Many people sought a "permanent" solution involving surgery. Openness to other treatment options was influenced by factors including understanding of pain, prior experiences, and treatment expectations.

CONCLUSION

These findings deepen our understanding of the impact of shoulder pain on peoples' lives and provide novel insight into the experience of treatment. Enhanced awareness of people's experiences of shoulder pain and treatment is crucial for clinicians when planning and implementing evidence-based recommendation.

IMPACT

To the knowledge of the authors, this is the first qualitative evidence synthesis to explore the treatment-related experiences of individuals with shoulder pain. Shoulder surgery was considered by many as the only means to achieve a more permeant resolution of symptoms.

LAY SUMMARY

Shoulder pain causes emotional and physical turmoil that can permeate every facet of life. People's understanding of their shoulder pain appears to be deeply rooted in a biomechanical view of pain, which influences their expectations relating to diagnosis and treatment.

Impaired health-related quality of life, psychological distress, and productivity loss in younger people with persistent shoulder pain: a cross-sectional analysis

PURPOSE

To investigate wellbeing and work impacts in younger people with persistent shoulder pain.

MATERIALS AND METHODS

People aged 20-55 years with shoulder pain of >6 weeks' duration (excluding those with recent fracture or dislocation) were recruited from orthopaedic clinics at three major public hospitals. Health-related quality of life (HRQoL) and psychological distress were evaluated using the Assessment of Quality of Life (AQoL) and K10 instruments and compared to population norms. Shoulder-related absenteeism and presenteeism were quantified using the Work Productivity and Activity Impairment (WPAI) Questionnaire.

RESULTS

Of the 81 participants (54% male), 69% had shoulder pain for over 12 months. Substantial HRQoL impairment was evident (mean reduction from population norms 0.33 AQoL units, 95% CI -0.38 to -0.27; minimal important difference 0.06 AQoL units). High or very high psychological distress was three times more prevalent among participants than the general population (relative risk 3.67, 95% CI 2.94 to 4.59). One-quarter of participants had ceased paid employment due to shoulder pain and 77% reported shoulder-related impairment at work.

CONCLUSIONS

The broader impacts of painful shoulder conditions on younger people extend well beyond pain and upper limb functional limitations. In particular, the work-related impacts should form a routine part of patient assessment and rehabilitation.Implications for rehabilitationPersistent shoulder pain in younger people (aged 20-55 years) is associated with substantially reduced health-related quality of life and greater psychological distress, compared to population norms, as well as work participation and productivity impacts.As rotator cuff conditions, shoulder capsule pathology, and glenohumeral instability are relatively common, our data suggest that persistent shoulder pain is likely to have a high community impact among people of working age.Information resources that people with painful shoulder conditions can share with their families, employers, and colleagues may assist others to better understand the broader impacts of these conditions.Work-related challenges associated with shoulder pain should be considered within routine clinical care, and may require referral to an occupational health clinician or vocational rehabilitation service.

Effectiveness of Focused Shockwave Therapy versus Radial Shockwave Therapy for Noncalcific Rotator Cuff Tendinopathies: A Randomized Clinical Trial

Background

The superiority of focused shockwave therapy (F-SWT) versus radial shockwave therapy (R-SWT) for treating noncalcific rotator cuff tendinopathies remains controversial. This study is aimed at comparing the effectiveness of F-SWT versus R-SWT for the management of noncalcific rotator cuff tendinopathies.

Methods

A total of 46 patients affected by noncalcific rotator cuff tendinopathies were randomly divided into 2 groups of 23 individuals. Patients in group A received 4 sessions of F-SWT, while patients in group B were treated by 4 sessions of R-SWT. In each session, mean energy flux density (EFD) for F-SW 3000 shots was 0.09 ± 0.018 mJ/mm² with 5.1 ± 0.5 Hz, while average pressure for R-SW 3000 shots was 4.0 ± 0.35 bar with 3.2 ± 0.0 Hz. Pain level and shoulder function were assessed with the numerical rating scale (NRS) and Constant-Murley Scale (CMS). The primary endpoint was the change in the mean NRS pain score from baseline to 24 weeks after the intervention. Secondary endpoints were changes in the mean NRS pain scores at all other follow-up points, changes in the mean CMS scores, and radiographic findings.

Results

There were no significant differences between the two groups regarding NRS pain score and CMS score within 24 weeks after intervention (all p > 0.05). However, F-SWT resulted in significantly lower NRS compared with R-SWT at 24 weeks and 48 weeks after treatment (2.7 ± 1.0 vs. 4.5 ± 1.2 and 1.4 ± 1.0 vs. 3.0 ± 0.8, respectively, all p < 0.001). Similar results were found in CMS changes and radiographic findings.

Conclusions

Both F-SWT and R-SWT are effective in patients with noncalcific rotator cuff tendinopathy. F-SWT proved to be significantly superior to R-SWT at long-term follow-up (more than 24 weeks). This trial is registered with ChiCTR1900022932.
