The single assessment numeric evaluation correlates with the western ontario rotator cuff score in non-traumatic shoulder disease.

Patient-reported outcome measures (PROMs) are essential clinical instruments used for assessing patient function and assisting in clinical decision making. The Western Ontario Rotator Cuff (WORC) index is the PROM for shoulder pathology with the most psychometric properties but is very time consuming. The Single Assessment Numeric Evaluation (SANE) method is a PROM that takes less time to answer and to analyze. The aim of the study is to evaluate the intra- class correlation between these two outcome scores in establishing shoulder function in patients with non-traumatic rotator cuff pathologies. Fifty five subjects of both genders and different ages presenting with non-traumatic shoulder pain for more than 12 weeks had a physical examination and ultrasound as well as MRI arthrogram scan findings that were consistent of a non-traumatic rotator cuff (RC) based pathology. On the same moment a WORC index and a SANE score questionnaire were filled in by the subject. The intra class correlation of both PROMs was statistically analyzed. The WORC index score and the SANE score show a moderate correlation with an Intra Class Coefficient (ICC) of r = 0.60 (95% CI:0.40-0.75). This study demonstrates a moderate correlation between the WORC index score and the SANE score in rating the disability of patients with atraumatic RC disease. The SANE score is applicable in research and clinical practice and is for the patient and the researcher an almost no time consuming PROM.

Residual intraperitoneal carbon dioxide gas following laparoscopy for adnexal masses: Residual gas volume assessment and postoperative outcome analysis.

Free residual gas after laparoscopy may cause shoulder pain, decreasing patient satisfaction with the procedure. We analyzed the correlation between postoperative residual carbon dioxide gas and shoulder pain, explored the peri- and postoperative factors associated with residual carbon dioxide and determined the effects of the use of a drainage tube. A cohort of 326 patients who underwent laparoscopic adnexal surgery between March 2005 and June 2018 at a teaching hospital in Korea was retrospectively analyzed through a medical records review. The enrolled patients were divided into 1-, 2-, and 3-port groups. The right volume, left volume, and total volume of residual gas were calculated using a formula based on measurements obtained from chest X-rays. Continuous variables were compared using Student t tests. Categorical variables were compared with the chi-square test or Kruskal-Wallis test. The total volumes of postoperative residual carbon dioxide gas were significantly different between the 1- and 2-port groups and between the 1- and 3-port groups (157.3 ± 179.2 vs 25.1 ± 92.3 mL and 157.3 ± 179.2 vs 12.9 ± 36.4 mL, respectively). The volume of residual gas and the time to the first passage of gas were positively correlated. The total volume of residual gas was more strongly correlated with the operative wound pain score than with the shoulder pain score. Additionally, the pre- and postoperative white blood cell counts, postoperative hospitalization duration, residual carbon dioxide volume, and shoulder pain score were significantly different between patients with and without a drainage tube. Although the volume of residual gas was not correlated with the shoulder pain score, the author found that both were lower in patients with a drainage tube than in those without, indicating that a drainage tube could be safely used to decrease residual gas volume and the shoulder pain score without increasing the risk of postoperative infection.

Effectiveness of an expert assessment and individualised treatment compared with a minimal home-based exercise program in women with late-term shoulder impairments after primary breast cancer surgery: study protocol for a randomised controlled trial.

BACKGROUND: In breast cancer patients, late-term upper limb sequelae, such as shoulder pain and impaired shoulder function, remain common after primary breast cancer surgery. The aim of this trial is to evaluate whether an expert assessment of shoulder impairments, followed by an individualised treatment plan, is superior to a minimal physiotherapeutic rehabilitation program in reducing shoulder symptoms, among women with late-term shoulder impairments after primary breast cancer. METHODS/DESIGN: The study is designed as a stratified, parallel-group, assessor-blinded, randomised, controlled trial conducted in Denmark; 130 participants with late-term shoulder impairments 3-7 years after primary surgery for breast cancer will be recruited. Participants will be randomised (allocation 1:1) to either an expert assessment of shoulder impairments followed by an individualised treatment plan or to follow a minimal physiotherapeutic rehabilitation program delivered in a pamphlet. The primary outcome will be a change in shoulder pain and function from baseline to 12 weeks after initiating the treatment, as measured by the patient-reported outcome Shoulder Pain and Disability Index (SPADI) questionnaire. DISCUSSION: There has been an insufficient focus in research and clinical practice on late-term shoulder impairment in women following surgery for breast cancer. This trial will focus on interventions towards late-term shoulder impairments and is expected to provide evidence-based knowledge to physiotherapists and women about the management of shoulder pain and impaired shoulder function. TRIAL REGISTRATION: ClinicalTrials.gov NCT05277909. Registered on 11 March 2022.

Assessment of shoulder rotation strength, muscle co-activation and shoulder pain in tetraplegic wheelchair athletes - A methodological study.

Objective: To develop a feasible protocol for testing maximum shoulder rotation strength in tetraplegic wheelchair athletes, and investigate concurrent validity of maximum isometric handheld dynamometer (HHD) towards maximum isokinetic dynamometer (ID) strength measurements; secondly, to study shoulder muscle activation during maximum shoulder rotation measurements, and the association between shoulder strength and shoulder pain.Design: Descriptive methodological.Setting: Danish Wheelchair Rugby (WCR) association for WCR tetraplegic athletes from local WCR-clubs.Participants: Twelve adult tetraplegics.Interventions: N/A.Outcome measures: Wheelchair User's Shoulder Pain Index (WUSPI) and Visual Analog Scale (VAS) measured shoulder pain, isometric HHD and ID (60°/s) measured maximum internal (IR) and external (ER) shoulder rotation strength. Surface Electromyography normalized to maximum EMG measured muscle activity (mm Infraspinatus and Latissimus Dorsi) during maximum shoulder rotation strength.Results: Concurrent validity of isometric HHD towards ID showed Concordance Correlation Coefficients of left and right arms 0.90 and 0.86 (IR), and 0.89 and 0.91 (ER), with no difference in muscle activity between isometric HHD and ID, but larger co-activation during ER. There was no association between shoulder strength and pain, except for significantly weak negative associations between ID and pain during ER for left and right arms (P = 0.03; P = 0.04).Conclusion: Standardized feasible protocol for tetraplegic wheelchair athletes for measuring maximum shoulder rotation strength was established. Isometric HHD is comparable with ID on normalized peak torques and muscle activity, but with larger co-activation. Strength was not clearly associated with shoulder pain.

Effect of Electroacupuncture on Shoulder Subluxation in Poststroke Patients with Hemiplegic Shoulder Pain: A Sham-Controlled Study Using Multidimensional Musculoskeletal Ultrasound Assessment.

OBJECTIVE: This study aimed to use multidimensional musculoskeletal ultrasound imaging technique to investigate the effect of electroacupuncture (EA) on shoulder subluxation in poststroke patients with hemiplegic shoulder pain. METHODS: In this prospective single-blind, randomized, sham-controlled study, thirty-four patients with shoulder subluxation and hemiplegic shoulder pain were recruited and randomly assigned into the EA group or the sham EA (SEA) group. In the EA group, EA was applied to the Jian yu (LI15), Bi nao (LI14), Jian zhen (SI9), and Jian liao (TE14) acupoints. In the SEA group, the EA was applied 15 mm away from the Lou gu (SP7), Di ji (SP8), Jiao xin (KI8), and Zhu bin (KI9) acupoints. Both groups underwent treatment 30 minutes/day, five days a week, for two weeks using dense waves with a frequency of 2/100 Hz. A Visual Analogue Scale (VAS) was used to evaluate the effectiveness of treatment in reducing shoulder pain. Musculoskeletal ultrasound was used to evaluate the changes of measures of shoulder subluxation in multidimensions (i.e., the acromiohumeral distance, AHD; acromion-greater tuberosity, AGT; and acromion-lesser tuberosity, ALT). Both the within- and between-groups treatment effects were assessed. RESULTS: The pain intensity measured by VAS and shoulder subluxation measured by musculoskeletal ultrasound (i.e., AHD, AGT, and ALT) showed significant (p < 0.05) within-group difference in both groups. The between-group difference appeared in the pain intensity (p < 0.05), while it disappeared in the three measures of shoulder subluxation (p > 0.05). CONCLUSIONS: Using VAS for measuring pain intensity and multidimensional musculoskeletal ultrasound imaging technique for measuring shoulder subluxation, this study finds that the hemiplegic shoulder pain can be improved significantly by the EA while the shoulder subluxation cannot be. Our findings further reveal the analgesic mechanism of EA on hemiplegic shoulder pain following stroke.

Ultrasound-guided versus blind subacromial bursa corticosteroid injection for paraplegic spinal cord injury patients with rotator cuff tendinopathy: a randomized, single-blind clinical trial.

INTRODUCTION: Shoulder pain is one of the common musculoskeletal complaints of the patients with spinal cord injury. Corticosteroid injection to the subacromial bursa is one of the confirmed therapies which can be guided by anatomic landmarks or ultrasound. This study is aimed to compare these two methods to find the one with the highest therapeutic impact. MATERIALS AND METHODS: In this study, 30 patients with paraplegic SCI suffering from shoulder pain were enrolled. They were divided into 2 groups based on 4-block randomization sampling. The first group received subacromial corticosteroid injection through anatomic landmarks; while in the second group, the injection was guided by ultrasound. VAS criterion was employed for investigation of pain severity; while the constant score was used to study the shoulder pain and function. BREF questionnaire was also applied to examine the quality of life. FINDINGS: The mean scores of VAS and Constant in both groups showed a significant improvement two months after intervention when compared with their condition before the intervention. This improvement was significantly higher in the ultrasound group. The physical, physiological and environmental health scores of BREF questionnaire as well as their total score showed a significant improvement in both groups two months after intervention. But this improvement was not significantly different between the two groups in terms of any of the items. DISCUSSION: Hence, although ultrasound-guided injection is more costly and requires higher skills in comparison with blind injection, it is significantly more effective in controlling the pain and improving the shoulder function.

Postoperative Pain Management and the Incidence of Ipsilateral Shoulder Pain After Thoracic Surgery at an Australian Tertiary-Care Hospital: A Prospective Audit.

OBJECTIVES: Ipsilateral shoulder pain (ISP) is a common but variably occurring (42%-85%) complication after thoracic surgery. Multiple potential treatments, including upper limb blocks, intrapleural local anaesthetic infiltration, and systemic opioids, have undergone trials, with limited efficacy. Phrenic nerve infiltration is a potential intervention that may prevent ISP. The aim of this study was to assess the incidence and severity of ISP after thoracic surgery at the authors' institution, where phrenic nerve infiltration is commonly used. DESIGN: Observational cohort study. SETTING: A single- center study in a tertiary referral center in Brisbane, Australia. PARTICIPANTS: This study comprised all adult patients undergoing thoracic surgery at a tertiary- care referral center from May to July 2018. MEASUREMENTS AND MAIN RESULTS: Surgical procedures were divided into open thoracotomy, video-assisted thoracic surgery (VATS) and VATS-guided mini-thoracotomy. The primary outcome was a comparison of incidence of ISP among the 3 types of surgical procedures. Data were analyzed using Stata (StataCorp), with significance testing by Kruskal-Wallis equality of populations rank test. A p value of < 0.05 was deemed significant. Sixty thoracic surgeries were performed during the audit period. Nineteen patients had thoracotomies performed for lobectomy or pneumonectomy, all of whom received phrenic nerve infiltration. The incidence of moderate-to-severe ipsilateral shoulder pain among the thoracoctomy cohort was 15.8% (3/19). Of the 36 VATS procedures audited, 7 patients (19.4%) received infiltration of their phrenic nerve, none of whom reported postoperative ISP. Of the remaining twenty-nine patients who did not receive phrenic nerve infiltration, there were 4 cases of moderate-to-severe ipsilateral shoulder pain (11.1%). Four of the 5 patients (80%) who underwent VATS-guided mini-thoracotomies received phrenic nerve infiltration intraoperatively. Three patients reported moderate-to-severe ISP and of these 3 patients, 2 patients had phrenic nerve infiltration, and 1 patient did not receive infiltration. Overall, there were no statistically significant differences in rest or dynamic pain scores across the surgical groups at any time point. Mann-Whitney test revealed that the participants with ISP were significantly older than those without ISP (p = 0.006). However, there were no significant differences in sex or body mass index between those with and without ISP. CONCLUSION: The authors observed a lower (15.8%) incidence of moderate-to-severe ISP among their thoracotomy patients than reported in prior literature. Injection of local anesthetic into the phrenic nerve fat pad at the level of the diaphragm appeared to be an effective and safe surgical intervention that may eliminate a significant cause of ISP. None of the VATS patients who received phrenic nerve infiltration experienced ISP. Postoperative pain in VATS is expected to be reduced by avoiding the use of a rib spreader, severing of the intercostal nerves, and division of muscle tissue, which may account for the lower observed rates of ISP in the VATS cohort who did not receive phrenic nerve infiltration. Further randomized controlled trials are warranted to establish if patients undergoing various VATS procedures benefit from this intervention.

Protocol for a randomised controlled trial of Subacromial spacer for Tears Affecting Rotator cuff Tendons: a Randomised, Efficient, Adaptive Clinical Trial in Surgery (START:REACTS).

INTRODUCTION: Shoulder pain due to irreparable rotator cuff tears can cause substantial disability, but treatment options are limited. A balloon spacer is a relatively simple addition to a standard arthroscopic debridement procedure, but it is costly and there is no current randomised trial evidence to support its use. This trial will evaluate the clinical and cost-effectiveness of a subacromial balloon spacer for individuals undergoing arthroscopic debridement for irreparable rotator cuff tears.New surgical procedures can provide substantial benefit to patients. Good quality randomised controlled trials (RCTs) are needed, but trials in surgery are typically long and expensive, exposing patients to risk and the healthcare system to substantial costs. One way to improve the efficiency of trials is with an adaptive sample size. Such methods are well established in drug trials but have rarely, if ever, been used in surgical trials. METHODS AND ANALYSIS: Subacromial spacer for Tears Affecting Rotator cuff Tendons: a Randomised, Efficient, Adaptive Clinical Trial in Surgery (START:REACTS) is a participant and assessor blinded, adaptive, multicentre RCT comparing arthroscopic debridement with the InSpace balloon (Stryker, USA) to arthroscopic debridement alone for people with a symptomatic irreparable rotator cuff tear. It uses a group sequential adaptive design where interim analyses are performed using all of the 3, 6 and 12-month data that are available at each time point. A maximum of 221 participants will be randomised (1:1 ratio), this will provide 90% power (at the 5% level) for a 6 point difference in the primary outcome; the Oxford Shoulder Score at 12 months. A substudy will use deltoid-active MRI scans in 56 participants to assess the function of the balloon. Analysis will be on an intention-to-treat basis and reported according to principles established in the Consolidated Standards of Reporting Trials statement. ETHICS AND DISSEMINATION: NRES number 18/WM/0025. The results will be disseminated via peer-reviewed publications, presentations at conferences, lay summaries and social media. TRIAL REGISTRATION NUMBER: ISRCTN17825590.

Shoulder pain among male industrial workers: Validation of a conceptual model in two independent French working populations.

This study aims to validate a conceptual model for shoulder pain risk factors in two independent samples of male industrial workers: the Cosali cohort (n = 334) and one pharmaceutical company (n = 487). Direct and indirect relationships between work organization factors (automatic speed of a machine or movement of a product and work pace dependent on customers' demand), psychosocial factors (Job strain model), biomechanical factors (working with abducted arms, working with arms at or above shoulder level, and perceived physical exertion), perceived stress, and shoulder pain were explored using structural equation models. Shoulder pain was positively associated with biomechanical exposure in both samples, and with perceived stress only in the pharmaceutical preparation manufacturer, while factors related to work organization and psychosocial factors had indirect impacts on the risk of chronic shoulder pain in both samples. The results provide a deeper understanding of the complex relationships between workplace risk factors and shoulder pain.

A value-based care analysis of magnetic resonance imaging in patients with suspected rotator cuff tendinopathy and the implicated role of conservative management.

BACKGROUND: Magnetic resonance imaging (MRI) is often used to evaluate the integrity of the rotator cuff in patients with suspected full-thickness rotator cuff tears or other cuff tendinopathies. The value of advanced imaging value comes into question when it is used as the initial musculoskeletal imaging test before a trial of conservative therapy in patients with atraumatic shoulder pain, minimal to no strength deficits on examination, and suspected cuff tendinopathy. METHODS: A prospective study of a group of patients suspected to have cuff tendinopathy based on clinical findings was performed. Every patient underwent MRI and was offered an initial trial of conservative management. Patients had an average follow-up of 28.3 ± 5.3 months after imaging to determine whether surgery was performed. RESULTS: A total of 51 patients were included in this study. Of this cohort, 46 (90.2%) patients did not go on to surgical intervention, whereas 5 (9.8%) patients did at an average 68.3 days after imaging. These results suggest that over 90.2% of patients (46 of 51) had premature MRI, posing an unnecessary economic burden of $181,619 in advanced imaging charges. CONCLUSIONS: The use of MRI before a trial of conservative management in patients with atraumatic shoulder pain, minimal to no strength deficits on physical examination, and suspected cuff tendinopathy other than full-thickness tears provides negative value in the management of these patients, at both the individual and population level.

The Distress and Risk Assessment Method predicts postoperative narcotic use in patients undergoing rotator cuff repair.

BACKGROUND: The Distress and Risk Assessment Method (DRAM) predicts poor outcomes in spine, hip, and knee surgery. Unlike other areas of orthopedic surgery, DRAM scores are not predictive of lower postoperative patient-reported outcomes after arthroscopic rotator cuff repair (RCR). PURPOSE: As concerns for opioid dependence and abuse grow, the purpose of this study was to analyze the correlation between preoperative DRAM scores, modified Zung scores, and postoperative narcotic use in patients who underwent arthroscopic RCR. MATERIALS AND METHODS: This prospective cohort study identified and enrolled patients >18 years of age with full-thickness rotator cuff tears at a single institution. Patients with prior shoulder surgery, greater than 1-tendon RCR, and preoperative narcotic use were excluded. One-hundred and fifty patients were enrolled, with 114 (76%) completing all preoperative and postoperative questionnaires. Preoperative DRAM scores were collected from every patient. Postoperative narcotic use was evaluated via survey and converted to total morphine equivalents. RESULTS: Increased preoperative DRAM scores predicted higher postoperative morphine equivalent units (P = .002, r = 0.29). When dividing patients into those <17 or ≥17 on the modified Zung score, 44 of 114 (39%) met criteria for "at risk or depressed." This group showed a statistically significant trend toward higher postoperative morphine equivalent unit intake (P = .004). CONCLUSION: Baseline psychological distress (DRAM) can predict narcotic requirements after RCR and serve as a powerful tool to identify patients at risk for increased narcotics requirements postoperatively. In our cohort, 39% of patients showed evidence of baseline depression, which highlights a potential role of the modified Zung score to identify patients in need of preoperative psychological counseling.

Comparative study of psychometric properties of three assessment tools for degenerative rotator cuff disease.

OBJECTIVE:: To compare psychometric properties of Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, Shoulder Pain and Disability Index (SPADI) and Constant-Murley scale, in patients with degenerative rotator cuff disease (DRCD). DESIGN:: Longitudinal cohort. SETTING:: One French university hospital. METHODS:: The scales were applied twice at one-week interval before physiotherapy and once after physiotherapy two months later. The perceived improvement after treatment was self-assessed on a numerical scale (0-4). The test-retest reliability of the DASH, SPADI and Constant-Murley scales was assessed before treatment by the intraclass correlation coefficient (ICC). The responsiveness was assessed by the paired t-test ( P < 0.05) and standardized mean difference (SMD). The correlation between the percentage of variation in scale scores and the self-assessed improvement score after treatment was measured by the Spearman coefficient. RESULTS:: Fifty-three patients were included. Twenty-six only were available for reliability. The test-retest reliability was very good for the DASH (ICC = 0.97), SPADI (0.95) and Constant-Murley (0.92). The scale score was improved after treatment for each scale ( P < 0.05). The SMD was moderate for the DASH (0.56) and SPADI (0.56) scales, and small for the Constant-Murley (0.44). The correlation between the percentage of variation in scores and self-assessed improvement score after treatment was high, moderate and not significant for the SPADI (0.59, P < 0.0001), DASH (0.42, P < 0.01) and Constant-Murley scales, respectively. CONCLUSION:: The test-retest reliability of the DASH, SPADI and Constant-Murley scales is very good for patients with DRCD. The highest responsiveness was achieved with the SPADI.

Home-Based Exercise Enhances Health-Related Quality of Life in Persons With Spinal Cord Injury: A Randomized Controlled Trial.

OBJECTIVE: To assess the influence of a home-based exercise intervention on indices of health-related quality of life (HRQOL) in persons with spinal cord injury (SCI). DESIGN: This was a randomized controlled trial (HOMEX-SCI; ISRCTN57096451). After baseline laboratory testing and a week of free-living physical activity monitoring, eligible participants were randomly assigned (2:1 allocation ratio) to a home-based moderate-intensity upper-body exercise intervention group (INT, n=13), or a lifestyle maintenance control group (CON, n=8), for 6 weeks. SETTING: Home-based with short laboratory visits immediately before and after the intervention/control period. PARTICIPANTS: Inactive participants (N=21) with chronic (>1yr) SCI (injury level

Neck-Shoulder Pain and Work Status among Former Sewing Machine Operators: A 14-year Follow-up Study.

Purpose A total of 243 Danish female sewing machine operators lost their jobs in 1996 because of outsourcing. The aim was to investigate the employment status during follow-up from 1996 to 2008, and to estimate to what extent former neck-shoulder pain had an impact on later work participation. Methods Assessment of neck-shoulder pain was based on questionnaires completed in 1994. The Danish Register-Based Evaluation of Marginalization (DREAM) register was used to describe employment status during the follow-up period. Register data were explored by sequence analyses and graphics, and the association between neck-shoulder pain and work participation was analyzed by logistic regression analysis. Results In all, 987 working years were lost during follow-up, and a sequence index plot revealed interrupted and heterogeneous courses of incomes. The odds ratio between neck and shoulder pain and a work participation score less than 75% was 1.49 (95% CI 0.84-2.67). Conclusions After outsourcing of the textile industry, the former sewing machine operators had decreased work participation and frequent transitions between different income types. Previous neck-shoulder pain tended to be associated with poor work participation. The results suggest that increased attention should be to given to dismissed workers from other industries that become outsourced, especially unskilled workers with similar work-related health limitations. Additionally, we concluded that time-to-event measures in research involving employment status are insufficient because of the many transitions that take place in working life.

Rehabilitation of symptomatic atraumatic degenerative rotator cuff tears: A clinical commentary on assessment and management.

STUDY DESIGN: Clinical Commentary. INTRODUCTION: Atraumatic rotator cuff (RC) disease, is one of the most common cause of shoulder pain, which encompasses a continuum from tendinopathy to full thickness cuff tears. Extrinsic, intrinsic and environmental factors have been implicated in the pathophysiology of this disorder, affecting the clinical presentation of symptoms including pain and irritability. Successful rehabilitation of symptomatic atraumatic degenerative rotator cuff (SADRC) tears must address the underlying mechanisms causing dysfunction and correct modifiable factors. PURPOSE OF THE STUDY: The purpose of this paper is to review the shoulder complex anatomy, introduce atraumatic degenerative RC pathology, differentiate between symptomatic and asymptomatic degenerative RC tears, propose an assessment and introduce the Rotator Cuff Protocol 1 (RCP1) designed by the clinical reasoning of one of the lead authors (LW) as a rehabilitation management approach for those clients who present with SADRC tears. METHODS/RESULTS/DISCUSSION: N/A for clinical commentary. CONCLUSIONS: The ability to identify SADRC tears should consider shoulder anatomy, extrinsic, intrinsic and environmental factors, and the consideration for the natural history of atraumatic partial and full thickness tears in the general population. A thorough clinical history and examination, which includes shoulder symptom modification tests, allows the examiner to determine at what phase the patient may start their exercise program. The RCP1 is a program that has been used clinically by many therapists and clients over the years and research is underway to test this protocol in atraumatic rotator cuff disease including SADRC tears.

The modified Norwegian method of biceps tenodesis: how well does it work?

PURPOSE: The purpose of this study was to evaluate clinical outcomes and complications in a series of patients who underwent the modified Norwegian method (MNM) of biceps tenodesis by a single shoulder surgeon. METHODS: A retrospective review of charts from all patients who underwent the modified Norwegian method of biceps tenodesis by the senior author during a 5-year period between 2008 and 2013 was performed. After all patients were identified, informed consent was obtained and DASH and ASES surveys were administered. Inclusion criteria for the study were a minimum 2-year follow-up after MNM tenodesis and appropriate adherence to DASH and ASES survey protocol. Data obtained included: demographic data, time to follow-up, hand dominance, concomitant procedures, workman's compensation (WC) status, DASH and ASES surveys, and complications. A complication was defined as rupture of the tenodesis or post-operative infection. Residual shoulder pain was considered as treatment failure. The data were then analysed using statistical software. In this time period, 94 biceps tenodeses using the MNM technique were performed. Follow-up rate was 75/94 patients (80 %). Of 75 patients, 15 (20 %) had an isolated tenodesis performed. RESULTS: There was no statistically significant difference in DASH or ASES scores when comparing isolated tenodesis patients to those who had concomitant procedures. WC patients had worse DASH and ASES scores (p = 0.016; p = 0.002). The complication rate was 2/75 (3 %), which were both ruptured tenodeses. Of 75 patients, 3 (4 %) experienced treatment failure with residual anterior shoulder pain. CONCLUSIONS: There is debate in the literature regarding the optimal method of biceps tenodesis. This paper demonstrates that the MNM tenodesis appears to be a simple, efficient, and effective alternative to other methods of biceps tenodesis with subjective outcome scores and complication rates that parallel other methods previously described in the literature.

Cross-Sectional Assessment of Factors Related to Pain Intensity and Pain Interference in Lower Limb Prosthesis Users.

OBJECTIVE: To determine relationships between pain sites and pain intensity/interference in people with lower limb amputations (LLAs). DESIGN: Cross-sectional survey. SETTING: Community. PARTICIPANTS: Lower limb prosthesis users with unilateral or bilateral amputations (N=1296; mean time since amputation, 14.1y). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Patient-Reported Outcomes Measurement Information System (PROMIS) pain intensity (1 item to assess average pain), PROMIS pain interference (4-item short form to assess the consequences of pain in desired activities), and questions that asked participants to rate the extent to which each of the following were a problem: residual limb pain (RLP), phantom limb pain (PLP), knee pain on the nonamputated side, back pain, and shoulder pain. RESULTS: Nearly three quarters (72.1%) of participants reported problematic pain in 1 or more of the listed sites. Problematic PLP, back pain, and RLP were reported by 48.1%, 39.2%, and 35.1% of participants, respectively. Knee pain and shoulder pain were less commonly identified as problems (27.9% and 21.7%, respectively). Participants also reported significantly (P<.0001) higher pain interference (T-score ± SD, 54.7±9.0) than the normative sample based on the U.S. population (T-score ± SD, 50.0±10.0). Participants with LLAs rated their pain intensity on average ± SD at 3.3±2.4 on a 0-to-10 scale. Pain interference (ρ=.564, P<.0001) and intensity (ρ=.603, P<.0001) were positively and significantly correlated with number of pain sites reported. CONCLUSIONS: Problematic pain symptoms, especially RLP, PLP, and back pain, affect most prosthetic limb users and have the potential to greatly restrict participation in life activities.

The Influence of Test Positions on Clinical Assessment for Scapular Dyskinesis.

BACKGROUND: Appropriate evaluation of scapular dyskinesis is essential for therapeutic strategies. Although the current visual-based assessment is rapid and practical, the reliability of this method is unsatisfactory. It is necessary to adequately understand the conditions of assessment to maximize the benefit of therapeutic interventions. OBJECTIVE: To explore the influence of different test positions on clinical assessment for scapular dyskinesis. DESIGN: Observational study. SETTING: University rehabilitation department. PATIENTS: A total of 102 subjects diagnosed with unilateral shoulder disorder were recruited from among rehabilitation outpatients from November 2015 to February 2016. METHODS: Two experienced raters categorized the subjects' scapular movement pattern according to Kibler et al classification by the vision-palpation method at 4 test positions (at rest, and the end range of elevation in the sagittal, scapular, and coronal planes). MAIN OUTCOME MEASUREMENTS: The overall prevalence of scapular dyskinesis, the distribution of types, and the reproducibility of types at the 4 test positions were analyzed. RESULTS: The overall prevalence of scapular dyskinesis was 90.08%, and the highest frequency was found at the resting position. Type III was the most common type in our sample. In reproducibility analysis, 21.57% of subjects presented with the same type at any position, and 75.49% of subjects presented with 2 types. CONCLUSIONS: Scapular dyskinesis in individuals with shoulder disorder showed a high prevalence, especially at the resting position. More than 1 type of scapular pattern would be present if assessed at different positions. This study indicates that test positions can affect the results of scapular dyskinesis assessment, and that the resting position should primarily be applied. LEVEL OF EVIDENCE: III.
