Referred Shoulder Pain Due to the Positioning of the Ventriculoperitoneal Shunt: A Case Report and Literature Review of an Unusual Complication.

We present the case of an 18-year-old male with a ventriculoperitoneal (VP) shunt for hydrocephalus who experienced right shoulder pain. The patient was thoroughly investigated for gastrointestinal disease, including abdominal ultrasound and upper endoscopy, which revealed no abnormalities that could explain his symptoms. X-ray imaging subsequently revealed that the shunt's distal peritoneal tubing was positioned in a supra-hepatic subdiaphragmatic location. Surgical shortening and repositioning of the peritoneal tubing successfully alleviated the patient's shoulder pain. A review of the literature uncovered four articles, comprising a total of six patients, who exhibited similar symptoms of shoulder pain linked to their VP shunts. Given the rarity of this complication, it can be easily overlooked or misdiagnosed. It is crucial for physicians to consider this possibility when evaluating patients with VP shunts who present with shoulder pain to ensure prompt and effective treatment.

Ultrasound-guided corticosteroid injection in the coracohumeral ligament in patients with Adhesive Capsulitis of the shoulder: A double-blinded, sham-controlled randomized study.

BACKGROUND: Contracture and thickening of the coracohumeral ligament (CHL) occur in patients with adhesive capsulitis. This adversely affects the movement and function of the shoulder joint. There is limited evidence that explores the effectiveness of an isolated steroid injection into CHL in combination with physical therapy. This prospective randomized control trial aimed to evaluate the clinical effects of ultrasound-guided corticosteroid injection compared to a sham injection into the CHL in subjects with adhesive capsulitis. METHODS: Forty patients (23 males, 52.2 ± 8 years of age) with unilateral adhesive capsulitis (with 5.4 ± 2 months mean duration of symptoms) were randomly assigned to either the experimental or control group. Both groups received ultrasound-guided injections into the CHL. The experimental group (n=20) received corticosteroids and the control group (n=20) received a sham lidocaine injection. All subjects underwent supervised conventional physical therapy three times a week for 3 months. Subjects were evaluated for improvements in pain, range of motion, and disability at 6 and 12 weeks as compared to pre-injection baseline measurements. Data were compared statistically across groups and times at p<0.05. The CHL thickness was compared at baseline across sides using paired t-tests. RESULTS: The experimental group showed statistically greater improvements in pain, functional scores, flexion, abduction, internal and external rotation range of motion at 12 weeks compared to the control group. Pain reduction was observed in both groups at 6 and 12 weeks, but the experimental group exhibited significantly greater reductions. The CHL was significantly thicker on the affected side as compared to the unaffected side (p<0.001). DISCUSSION AND CONCLUSION: This study partially supported the hypothesis. Notably, significant improvements in pain, range of motion, and functional scores were observed at 12 weeks in the experimental group. The greater improvements in pain and external rotation may have resulted in lower disability scores in the experimental group. The results emphasize the importance of targeted intervention into the CHL.

Assessment approaches for hemiplegic shoulder pain in people living with stroke - A scoping review.

PURPOSE: Hemiplegic shoulder pain (HSP) is reported in up to 40% of people with stroke. Causes of HSP are often multifactorial. To inform appropriate treatment, reliable/valid assessments are critical. The aim of this scoping review was to collate assessment approaches used in studies where the primary outcome was HSP, and to identify how frequently each assessment approach was used. METHODS: A systematic search, including studies from 2000-2023 was conducted of the MEDLINE, EMBASE, CINAHL, AMED, Biomed Central, and Cochrane Library databases, with four key terms used: "assess", "stroke", "pain" and "shoulder". All primary studies published in English language fulfilling the reviews inclusion criteria were included. Six reviewers extracted the data. RESULTS: A total of 29 assessment methods for HSP were identified from 124 studies. The common assessments were: Visual Analogue Scale (n = 75, 60%), Passive Range of Movement (n = 65, 52%), Fugl-Meyer Assessment (n = 32, 26%), glenohumeral subluxation (n = 30, 24%) and Numerical Rating Scale (n = 27, 22%). CONCLUSION: A wide range of assessment approaches was identified for HSP, and some are used more than others. A fully comprehensive assessment that considers different aspects of pain including severity and timing, functioning, and the psychological burden, is needed in this area of practice to be able to guide appropriate treatment.

Hemiplegic shoulder pain is reported in up to 40% of people with stroke and a wide range of assessments approaches are reported in the literature.Simple questioning about shoulder pain may not be adequate for providing the best clinical care to patients and an ideal assessment approach would be one that takes into consideration both quantitative and qualitative information.Until a new measure is developed, the four common assessments reported (Visual Analogue Scale; Passive Range of Movement; Fugl-Meyer Assessment and Numerical Rating Scale) should be used in combination.

The prevalence of cervical contribution in patients reporting shoulder pain. An observational study.

BACKGROUND: Shoulder pain is the third most common musculoskeletal disorder yet diagnosis remains challenging. In some cases, shoulder symptoms can be partially attributed to a cervical origin. OBJECTIVES: To estimate the prevalence of cervical contribution in patients presenting with shoulder pain. To determine symptom reproduction and symptom modification (i.e., pain intensity and pain location) after cervical spine screening (CSS) and compare these changes between patients with and without cervical contribution. DESIGN: Observational study. METHOD: Sixty patients were included. Cervical contribution was present if a ≥30.0% change in shoulder pain intensity on active movement was recorded after CSS. The CSS consisted of several tests and shoulder symptom modification or reproduction was noted. The presence of a centralization phenomenon was also noted and was considered to be present if the location of pain diminished from more distal areas after the CSS. RESULTS: A 50.0% prevalence of cervical contribution (CI95% 37,35-62,65) was found. Cervical contribution was more likely in those that demonstrated centralization of their pain after the CSS (p = 0.002) and those that had a history of previous neck pain (p = 0.007). Symptom reproduction occurred for 23 out of the 60 participants (38.3%), being present in 18 of those with cervical contribution (60.0%). After the CSS, a statistically significant decrease of shoulder pain intensity was found for those classified as having cervical contribution (p < 0.001). CONCLUSIONS: Cervical contribution is prevalent in 50% of patients presenting with shoulder pain; this was evidenced as shoulder symptom modification and, to a lesser extent, symptom reproduction following a CSS.

Assessing the Impact of Smartphone Use on Neck Pain and Related Symptoms Among Residents in Jeddah, Saudi Arabia: A Cross-Sectional Study.

BACKGROUND: The widespread adoption of smartphones has transformed global communication but raised health concerns like Text Neck Syndrome - a musculoskeletal condition arising from prolonged device use, causing discomfort in the cervical spine. This study investigates its prevalence and associated factors among smartphone users in Jeddah, Saudi Arabia, focusing on usage patterns, symptoms, and awareness. METHODS: This cross-sectional online survey was conducted from June 1 to June 30, 2024. Data on demographics, smartphone habits, symptoms, and Text Neck Syndrome awareness were collected using a structured questionnaire. Statistical analysis involved descriptive statistics and chi-square tests. RESULTS: The study included 421 participants, predominantly female (279, 66.3%) and Saudi nationals (397, 94.3%). The largest age group was 21-40 years (308, 73.2%), and most were single (251, 59.6%) with a college degree (236, 56.1%). Over 42.0% of participants used smartphones for more than five hours daily, with 39.4% adopting a 30-degree neck posture. The most prevalent symptoms reported were neck pain (272, 64.6%), headaches (203, 48.2%), and shoulder pain (178, 42.3%). Awareness of Text Neck Syndrome was reported by 197 participants (46.8%), but only 60 (14.3%) had been diagnosed. Concerns about long-term complications such as osteoporosis (105, 24.9%) and prolapsed intervertebral disc (120, 28.5%) were expressed. Despite these concerns, 97.9% of participants hesitated to reduce smartphone usage due to reported symptoms. CONCLUSION: This study highlights the significant musculoskeletal impact of smartphone use in Jeddah, underscoring the need for interventions promoting ergonomic practices and increasing awareness about associated risks. Public health strategies should focus on promoting ergonomic practices and educating users about preventive measures.

Woman With Shoulder Pain: Posterior Shoulder Dislocation Diagnosed With Point-of-Care Ultrasound.

Posterior shoulder dislocations are relatively rare. When used by emergency medicine physicians, point-of-care ultrasound (POCUS) demonstrates higher sensitivity and specificity for diagnosing shoulder dislocation as compared to two-view plain films. A 49-year-old woman presented to the emergency department (ED) with left shoulder pain following a mechanical fall. Physical examination was remarkable for a gross shoulder deformity and tenderness over the left proximal humerus. POCUS of the left shoulder using a curvilinear probe and a posterior approach was performed and demonstrated posterior displacement of the humeral head relative to the glenoid. Anteroposterior and oblique shoulder X-rays were read as unremarkable by the radiologist; a computed tomography of the shoulder confirmed a posterior shoulder dislocation. Given its efficacy and efficiency as compared to X-ray radiography, POCUS should be strongly considered in the diagnosis and management of posterior shoulder dislocations in the ED setting.

Short-term effects of Kinesiotaping combined with a rehabilitation program for rotator cuff-related shoulder pain: a randomized, assessor-blinded clinical trial.

OBJECTIVES: This study aimed to determine the clinical efficacy of Kinesiotaping (KT) combined with a rehabilitation program to reduce symptoms and functional limitations in patients with Rotator Cuff-Related Shoulder Pain (RCRSP) in Vietnam. METHODS: In total, 82 participants who were diagnosed with RCRSP were randomly allocated into two groups. Both groups received a standard rehabilitation program; additionally, the intervention group was treated with KT. Outcomes, assessed at baseline, and 3, 7, and 14 days postintervention, included pain intensity (Visual Analogue Scale, VAS), functional disability (Shoulder Pain and Disability Index, SPADI), and active range of motion (ROM). RESULTS: The KT group exhibited significant improvements in all outcome measures. VAS scores decreased by an average of 13.3 points in the KT group at 14 days, which was notably greater than that in the control group (95% CI: -17.77 to -8.82). SPADI scores also improved significantly in the KT group, with reductions of -11.36, -15.27, and -13.3 at days 3, 7, and 14, respectively. Regarding ROM, the KT group showed notable improvements in flexion and external rotation, with flexion ROM differences of 10.78, 10.35, and 11.8 degrees at the respective time points. No significant changes were observed in the abduction or internal rotation ROM. After adjusting for age, baseline scores, and gender, there was a statistically significant interaction between Group and Time on the VAS, SPADI, and ROM abduction. CONCLUSION: Incorporating KT into a standard rehabilitation program for RCRSP demonstrated enhanced efficacy in reducing pain and improving shoulder function. The results suggest that KT can be a valuable component of the treatment regimen for RCRSP.

Pain, function and peritendinous effusion improvement after dry needling in patients with long head of biceps brachii tendinopathy: a single-blind randomized clinical trial.

INTRODUCTION: Long head of biceps brachii tendinopathy, a frequent source of anterior shoulder pain, may lead to discomfort and diminished function. The objective of this study is to assess the efficacy of dry needling and transcutaneous electrical nerve stimulation in these patients. PATIENTS AND METHODS: Thirty patients were randomized into dry needling and transcutaneous electrical nerve stimulation groups and assessed before treatment, 8 and 15 days after treatment using a visual analogue scale, shoulder pain and disability index, pressure pain threshold, tissue hardness, and biceps peritendinous effusion. RESULTS: Both treatments significantly reduced the visual analogue scale in immediate (p < 0.001), short-term (p < 0.01), and medium-term effects (p < 0.01). Dry needling outperformed transcutaneous electrical nerve stimulation for the pain (p < 0.01) and disability (p < 0.03) subscales of the shoulder pain and disability index in the short-term and medium-term effects, respectively. Pressure pain threshold increased after both treatments but didn't last beyond 8 days. Neither treatment showed any improvements in tissue hardness of the long head of biceps brachii muscle. Notably, only the dry needling group significantly reduced biceps peritendinous effusion in both short-term and medium-term effects (p < 0.01). CONCLUSIONS: Dry needling showed non-inferior results to transcutaneous electrical nerve stimulation in reducing pain and disability and demonstrated even superior results in reducing biceps peritendinous effusion (see Graphical Abstract). TRIAL REGISTRATION: The Institutional Review Board of the China Medical University Hospital (CMUH107-REC2-101) approved this study, and it was registered with Identifier NCT03639454 on ClinicalTrials.gov.

Both dry needling and transcutaneous electrical nerve stimulation effectively reduced pain in the long head of biceps brachii tendinopathy.Dry needling outperformed transcutaneous electrical nerve stimulation in short-term and medium-term pain and disability relief, respectively.Dry needling demonstrated superior results in reducing biceps peritendinous effusion compared to transcutaneous electrical nerve stimulation.

Psychosocial Factors, Sleep, and Central Pain Processing for Making a Prognosis About Recovery of Pain, Function, and Quality of Life After Rotator Cuff Repair: An Exploratory Longitudinal Study.

OBJECTIVE: To explore modifiable psychosocial factors, sleep-related variables, indices of central pain processing and patients' characteristics as potential prognostic factors for pain, shoulder function, and quality of life (QoL) 1 year after rotator cuff repair. DESIGN: This observational longitudinal study included 142 patients who were undergoing rotator cuff repair. All measures took place pre-rotator cuff repair (T0), and 12 weeks (T1) and 12 months (T2) after rotator cuff repair. METHODS: Mixed-effects linear regression modeled relationships between the Western Ontario Rotator Cuff Index (WORC, model A), the Subjective Shoulder Value (SSV, model B), and EuroQol's EQ-5D-5L for QoL (model C), and potential prognostic factors over time. Factors included psychosocial variables, sleep-related indices, and proxies of central pain processing. Patients' age, sex, and body mass index complemented the analyses. RESULTS: At follow-up (T2), data from 124 participants were available for analysis. Five prognostic factors were identified for the 1-year outcome. Better expectations for symptom reduction (P<.0001, -1.4 mm) and an increase in Douleur Neuropathique 4 score (P = .0481, -0.9 mm) affected the evolution of WORC over time (model A). An increase in injury perception subscale consequence (P = .0035, 0.04%) influenced the SSV trajectory (model B). In addition, when sleep quality (P = .0011, -0.13%) and sleep efficiency (P = .0002, 0.005%) improved, the EQ-5D-5L slope was affected (model C). CONCLUSION: Addressing cognitions, pain mechanisms and sleep behavior prior to rotator cuff repair can identify people who are at risk of a poor outcome after surgery.

Intramuscular lipomas posing diagnostic and pre-operative counselling challenges in a low-resource setting: A case series.

INTRODUCTION: Intramuscular lipomas (IMLs) are uncommon primary adipose tissue tumours deep within the muscle. A high likelihood of misdiagnosing them as other benign and malignant masses necessitates imaging studies to confirm the diagnosis and plan treatment. Ultrasonography is useful but CT and MRI provide a more accurate diagnosis. While diagnostic tests are suitable, they may not always be accessible or affordable in low-resource settings. We present three cases of IMLs that emphasise the difficulties posed by limited resources and the significance of a comprehensive medical history and physical examination in low-resource settings. PRESENTATION OF CASES: The patients included a 57-year-old male with a distal right thigh mass, a 65-year-old female with a proximal right thigh mass, and a 60-year-old female with a mass at the left scapular area. The three patients underwent surgical excision and had an uneventful postoperative course, with no reported recurrence during their ongoing follow-up. DISCUSSION: The management of IMLs is not complicated if the requisite resources are available. Conversely, in low-resource settings with limited diagnostic facilities and human expertise, management may take a challenging path. Patient 1, despite undergoing diagnostic tests confirming IML, initially declined treatment due to challenges with pre-operative counselling. Patients 2 and 3 lacked health insurance and could not afford diagnostic imaging tests. CONCLUSION: Healthcare professionals in low-resource settings should familiarise themselves with the clinical characteristics and pathology of IMLs to minimise misdiagnosis and ensure appropriate counselling is provided to patients. IMLs are slow-growing mostly asymptomatic benign swelling. On physical examination, they are usually non-tender, soft, masses, not fixed to the bed or overlying tissue. The overlying skin is normal and lymphadenopathy is absent.

Shoulder mobility and strength impairments in patients with rotator cuff related shoulder pain: a systematic review and meta analysis.

Background: The methods previously proposed in the literature to assess patients with rotator cuff related shoulder pain, based on special orthopedic tests to precisely identify the structure causing the shoulder symptoms have been recently challenged. This opens the possibility of a different way of physical examination. Objective: To analyze the differences in shoulder range of motion, strength and thoracic kyphosis between rotator cuff related shoulder pain patients and an asymptomatic group. Method: The protocol of the present research was registered in the International Prospective Register of Systematic Review (PROSPERO) (registration number CRD42021258924). Database search of observational studies was conducted in MEDLINE, EMBASE, WOS and CINHAL until July 2023, which assessed shoulder or neck neuro-musculoskeletal non-invasive physical examination compared to an asymptomatic group. Two investigators assessed eligibility and study quality. The Newcastle Ottawa Scale was used to evaluate the methodology quality. Results: Eight studies (N = 604) were selected for the quantitative analysis. Meta-analysis showed statistical differences with large effect for shoulder flexion (I2 = 91.7%, p < 0.01, HG = -1.30), external rotation (I2 = 83.2%, p < 0.01, HG = -1.16) and internal rotation range of motion (I2 = 0%, p < 0.01, HG = -1.32). Regarding to shoulder strength; only internal rotation strength showed statistical differences with small effect (I2 = 42.8%, p < 0.05, HG = -0.3). Conclusions: There is moderate to strong evidence that patients with rotator cuff related shoulder pain present less shoulder flexion, internal and external rotation range of motion and less internal rotation strength than asymptomatic individuals.

Effects of acupuncture on pain and function in patients with subacromial impingement syndrome: A randomized sham-controlled trial.

Background: Subacromial impingement syndrome (SIS) is the most common cause of shoulder pain. Acupuncture is a traditional medicine that is effective on pain. This study aimed to evaluate the effect of acupuncture treatment on pain, function, range of motion (ROM) and quality of life compared to sham acupuncture in patients diagnosed with SIS. Methods: A randomized, prospective, double-blinded, sham-controlled trial was conducted. In acupuncture group 40 participants received acupuncture treatment plus exercise therapy while in control group 40 participants received sham acupuncture plus exercise therapy. Primary outcomes included pain-rest, activity and night pain. Secondary outcomes included function [Shoulder Pain and Disability Index (SPADI) and The Disabilities of the Arm, Shoulder and Hand Score (Quick DASH)], ROM, and quality of life [The Western Ontario Rotator Cuff Index (WORC)] in patients with SIS. Results: Both groups had significant improvements for pain-rest, activity night pain scores, SPADI, Quick DASH and WORC after treatment and at the first month follow-up. Significant improvements were recorded in the acupuncture group for all ROM after treatment and at the first month follow-up while in control group only in passive internal rotation. Acupuncture group had better improvements for Quick DASH, WORC and all ROM parameters after the treatment, as well as for all parameters except pain-night and passive flexion at the first month follow-up. Conclusion: This study suggest that acupuncture treatment is a safe, effective and non-invasive treatment option in patients with SIS. Trial registration: The study protocol is registered at clinicaltrials.gov (NCT05794633).

Effects of laptop screen height on neck and shoulder muscle fatigue and spine loading for office workers.

BACKGROUND: Due to the unfavourable neck-shoulder muscle loads caused by poor posture, the people who use the laptop for a long time may face the risk of neck and shoulder injuries. OBJECTIVE: The purpose of this study investigates the impact of the screen height on the muscle activation of head flexion, neck and shoulder, and the cervical spine torque to provide the favorite screen height for laptop user. METHODS: Twelve healthy young participants completed a15-minute task of the reading at the four different screen heights. sEMG signals of the splenius capitis (SC) and upper trapezius (UT) were measured and calculated the root mean square (RMS) and mean power frequency (MPF) to determine muscle fatigue. The different height of laptop users was simulated and the forces on the spine of users at different screen heights were analyzed by Jack. RESULTS: Adjusting the height of the laptop screen can effectively reduce head flexion and muscle activity of SC and UT, and has a positive effect on reducing fatigue of SC, but has no significant effect on UT. CONCLUSIONS: Adjusting the height of the laptop screen can delay the occurrence of SC muscle fatigue to a certain extent. The joint analysis of sEMG spectrum and amplitude reports that the screen heights of D15 and D45 have the highest and the lowest frequency of fatigue, respectively. At the same time, the moment of spineT1/T2 and spineL4/L5 decrease with the increase of screen height.

An Unusual Pattern of Scapular Avulsion Fracture in the Spine: A Case Study.

Acromion fractures, particularly isolated cases, are uncommon but significant in shoulder injuries. There is no universally accepted treatment protocol, but the classification of the fracture helps to guide clinical decisions. We present a case report aiming to contribute to the understanding of treatment options for acromion fractures. A 22-year-old male sustained a left shoulder injury during a wrestling match, resulting in a type 2 acromion fracture. Conservative treatment was initiated with regular follow-ups. Serial imaging showed no further displacement. Gradual rehabilitation exercises were introduced based on healing progress. The rarity of isolated acromion fractures complicates their management. Conservative management, coupled with rehabilitation exercises, yielded positive outcomes in our case, suggesting its efficacy as a primary treatment option for isolated displaced acromion fractures. Further research is needed to establish standardized protocols for managing such fractures, but until then, conservative care remains a viable approach, potentially preferred over surgical intervention.

EFFECTIVENESS OVER TIME OF THE REVERSE SHOULDER PROSTHESIS FOR ACUTE PROXIMAL HUMERAL FRACTURE.

BACKGROUND: Reverse shoulder arthroplasty (RSA) has proven to be an effective surgical procedure for irreparable rotator cuff tears, comminuted fractures of the proximal humerus and shoulder arthroplasty revision surgeries. We know from the literature that the functional results are good in the short term, but not whether these results remain stable in the long term or, on the contrary, show a deterioration in functionality. OBJECTIVE: This study aims to analyze the functionality, degree of satisfaction, complications, and prosthesis survival at different cut-off points in patients with complex proximal humerus fractures treated with RSA, with a minimum postoperative follow-up of 7 years. MATERIAL AND METHODS: Analytical, longitudinal and prospective observational study of a cohort of patients treated for a fracture of the proximal humerus with PIH. Functional outcome was assessed using the Constant scale and the Constant adjusted for age and gender of the patients. Quality of life was measured using the University of California at Los Angeles Shoulder Assessment scale (UCLA) and the Disability of the Arm, Shoulder and Hand score scale (QuickDASH). In addition, range of motion, pain and radiological variables of loosening, scapular notching and tuberosity consolidation were assessed. RESULTS: Thirty-three patients were included with a mean postoperative follow-up of 8.3 years (range 7-12 years). There was a progressive and significant decrease in Constant score at 5and7years follow-up compared to the baseline assessment 2 years after surgery, although the effect size was not significant. The age- and sex-adjusted Constant as well as the UCLA scale did not show statistically significant variations at follow-up. Both shoulder abduction and anterior shoulder flexion correlated well with the final QuickDASH score. Radiological variables did not influence any of the study outcome variables. CONCLUSION: The functionality and quality of life of patients with complex proximal humerus fractures treated with RSA decreased significantly compared to the 2-year evaluation, although this change was not clinically relevant. Survival of RSA was satisfactory in the medium to long term with a low complication rate.

Is playing ma-jong, chess and cards associated with a lower incidence of shoulder pain in Chinese elderly adults? The cross-sectional and longitudinal evidence from CHARLS.

BACKGROUND: The association between playing Ma-jong, chess and cards (PMCC) and shoulder pain among elderly adults in China remains unclear. The present study aimed to examine the association based on a nationally representative large-scale survey. METHODS: The study used two waves of data from China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018. All subjects met the inclusion criteria were classified based on the results of the CHARLS wave questionnaire. Logistic regression models were conducted to analyze the cross-sectional and longitudinal association between PMCC and shoulder pain. Odds ratios (OR) were reported to indicate the strength of the association. RESULTS: In total, 8125 participants aged over 60 years (48.3 % male; mean age 67.9 ± 6.4 years) were enrolled in a cross-sectional association study in 2015, and further 6861 elderly adults were followed up in 2018. The overall prevalence of shoulder pain in the cross-sectional population was 15.6 %. In the non-PMCC and PMCC groups, the incidence of shoulder pain was 16.6 % and 10.7 %, respectively (P < 0.001). In the fully adjusted model, the results showed a significant association between PMCC and shoulder pain (OR: 0.798, 95 % CI: 0.662-0.963, P = 0.018). In the longitudinal analysis from 2015 to 2018, the incidence of new-occurrence shoulder pain in non-PMCC and PMCC groups was 22.1 %, and 18.5 %, respectively (P = 0.004). In the fully adjusted model, compared with the non-PMCC group, the risk of the occurrence of shoulder pain for individuals with PMCC was lower (OR: 0.832, 95 % CI: 0.709-0.975, P = 0.023). CONCLUSIONS: PMCC is associated with lower incidence of shoulder pain, which provides evidence for PMCC as a potential protective factor in the occurrence of shoulder pain.

Rehabilitation in subjects with frozen shoulder: a survey of current (2023) clinical practice of Italian physiotherapists.

OBJECTIVE: Frozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions. AIM: The aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature. METHODS: A web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices. RESULTS: A total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients' compliance with exercises at home and for motivational/educational purposes. DISCUSSION AND CONCLUSION: The clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

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.

Improvement in Sleep Disturbance Following Arthroscopic Rotator Cuff Repair.

BACKGROUND: Approximately 90% of patients express concerns with sleep shortly after developing shoulder-related symptoms. Previous small cohort studies have demonstrated the impact of rotator cuff repair on sleep, but none have characterized the observed benefits. The purpose of this study is to evaluate sleep improvement after rotator cuff repair including the speed of sleep recovery, the time at which improvement plateaus, and the longer-term maintenance of improved sleep. METHODS: A retrospective review of our institution's shoulder and elbow repository identified patients who underwent primary arthroscopic rotator cuff repair from 2012 - 2021 and reported sleep disturbance preoperatively. Patients were evaluated using sleep-related questions from the Simple Shoulder Test and American Shoulder and Elbow Surgeons score. Sleep outcomes were compared from a preoperative visit to 3-month, 6-month, 12-month, and most recent follow-ups to evaluate efficacy of treatment, speed of recovery and improvement plateaus. RESULTS: Among 677 RCR patients, 95.7% (648/677) reported sleep disturbance preoperatively. A total of 474 met inclusion criteria with median follow-up of 4.1 years (IQR, 2.1-6.1). At most recent follow-up, 81.8% were able to sleep comfortably and 65.7% were able to sleep on the affected side. A plateau in the ability to sleep comfortably was seen at 6 months while no plateau was observed in the ability to sleep on the affected side. More rapid improvement in the ability to sleep comfortably occurred during the first 3 months and from 3 - 6 months for the ability to sleep on the affected side. CONCLUSION: The majority of patients with sleep disturbance who undergo RCR, report significant, rapid, and lasting improvement in the ability to sleep comfortably and the ability to sleep on the affected side.

Real-world evidence of durable multi-dimensional improvement after 60-day peripheral nerve stimulation treatment used for shoulder pain.

Aim: This real-world analysis aims to quantify improvements in multiple health domains in patients who received 60-day peripheral nerve stimulation (PNS) for shoulder pain. Materials & methods: Patients reported percent pain relief and Patient Global Impression of Change in quality of life, physical function and sleep at the end of treatment (EOT), 3 months, and 6 months. Results: Of 768 patients, 80.7% were responders in at least one domain at EOT. In a subset who were followed up, a cumulative 75% continued to respond in at least one domain through 6 months (85% [n = 140/165] at 3 months and 88% [n = 53/60] at 6 months). Conclusion: 60-day PNS used for shoulder pain produced multi-dimensional improvements across health domains at EOT and through 6 months.

Chronic shoulder pain is common. Patients often have challenges with quality of life, physical function and sleep. Peripheral nerve stimulation (PNS) is one available treatment for chronic shoulder pain. Studies like this one show how treatments work in everyday use. These studies are important to help patients and doctors make decisions about their treatment. This study looked at patients who received a 60-day PNS treatment for their shoulder pain. The treatment involved one or two small wires placed through the skin to stimulate nerves in the shoulder. At the end of treatment, they reported how much pain relief they had. They also reported how much their quality of life, physical function and sleep changed. Of 768 patients, most (80.7%) had improvement in at least one of these areas at the end of their PNS treatment. Only 5.9% of patients reported complications. The most common complaint was skin irritation. A smaller group of patients also shared how they were doing 3 months and 6 months after starting treatment. Overall, about 75% of patients continued to have improvement in at least one area 6 months after starting treatment. For many people, PNS provided improvements in pain and in other areas important to patients. These results suggest that 60-day PNS can be a valuable treatment for people with shoulder pain.
