A Scoping Review of the Evidence regarding Assessment and Management of Psychological Features of Shoulder Pain.

METHODS: A scoping review of research studies identified through PubMed, EMBASE, and CINAHL and graduate theses identified using Google Scholar was conducted to determine studies and systematic reviews that addressed the management of psychological aspects of shoulder pain with or without neck pain. The search terms included psychological factors, anxiety, depression, catastrophic thinking, fear of movement, and psychological treatments. Two investigators screened study titles and abstracts. Data extraction, content analysis, and thematic coding focused on the dimensions of pain addressed (emotional, behavioural, and cognitive) and treatment approaches used (dimensions targeted, specific treatment parameters) and the linkage between treatment targets/rationale with interventions/outcomes measured. RESULTS: Ten studies (seven randomized trials and three cohorts) were identified that addressed the psychological aspects of shoulder pain. Out of seven RCTs, four compared psychological interventions with usual care. Eight studies used cognitive approaches, including emotional freedom techniques (EFT), pain coping strategies (PCS), physical-cognitive-mindfulness training (PCMT), psychological flexibility, face-to-face cognitive-behavioural treatment (CBT), and cognitive therapy using virtual reality (V.R.). Three studies used the behavioural approaches as their intervention, including behavioural therapy and Graded Exercise Therapy (GET). Pain intensity was addressed as the primary outcome in two studies and as a secondary outcome in five studies. Cognitive factors were evaluated in 50% of the articles using nine different measures. Emotional factors were evaluated in 80% of articles using ten different measures. Reduction of pain intensity and catastrophic thinking concerning pain was achieved in most studies using a biopsychosocial approach (70%). Applying a behavioural approach was associated with reductions in kinesiophobia and pain catastrophizing. Cognitive approaches had a positive association with reductions in the emotional aspect of pain. Only one study specifically linked rationale or specific physical and psychosocial treatment targets with the treatments provided and outcomes measured. CONCLUSIONS: Small pools of studies indicate that the rationale and treatment targeting are poorly defined in biopsychosocial interventions for shoulder pain. However, these benefits have been demonstrated when cognitive or behavioural components are added to the standard physical treatment of shoulder pain. A better definition of treatment targets, description of intervention components, and linkage of outcomes to targets are needed to advance our understanding of optimizing bio-psychosocial approaches.

Psychosocial Factors Are Associated with Electronic Portal Registration.

BACKGROUND: Electronic health records often include a portal for secure patient-clinician communication. There is evidence that use of electronic portals increases satisfaction, treatment adherence, safety, and clinical outcomes. We want everyone to enjoy these benefits and we noticed low and uneven portal use. We studied factors that we can address to improve portal use. QUESTIONS/PURPOSES: After controlling for differences in patient characteristics, what psychological and demographic factors are associated with an increased likelihood of registering for an electronic health record portal among people seeking musculoskeletal specialty care? METHODS: We reviewed data on 5672 adult English or Spanish-speaking patients seen in a musculoskeletal specialty office between October 2017 and December 2019. Eighteen percent (996 patients) had missing measures of symptoms of depression and anxiety due to intermittent problems with survey technology, leaving 4676 for analysis, 42% (1970 of 4676) men and 58% (2706 of 4676) women with a mean age of 51±15, 76% (3569 of 4676) of patients were English speaking, 22% (1015 of 4676) were Spanish speaking, and 2% (92 of 4676) spoke another language. Seventy-seven percent (3620 of 4676) of patients were residents of Austin, Texas, USA, 4% (159) were from Pflugerville, Texas, USA, 3% (143) were from Del Valle, Texas, USA, and 16% (754 of 4676) were from other areas of Texas. Ninety nine percent of patients were residents of Texas (4645 of 4676). Twenty-three percent of patients visited the upper extremity team (1077 of 4676), 37% the lower extremity team (1721 of 4676), 21% the back and neck team (1002 of 4676), and 19% the sport medicine team (876 of 4676). Seventy eight percent of patients (3654 of 4676) registered in portal and 22% (1022 of 4676) did not. The omitted population were not different from our study population in terms of age, gender, language, residence, and region of symptoms. We used a two-question measure of symptoms of depression (Patient Health Quality-2 [PHQ-2]) and a two-question measure of symptoms of anxiety (General Anxiety Disorder-2 [GAD-2]). The primary outcome was portal registration. To account for potential confounding, a multivariable logistic regressions model was used to determine the influence of age, spoken language, city and state of residence, care team, number of completed visits and GAD and PHQ scores on portal registration. RESULTS: After controlling for potentially confounding variables such as state of residence, we found younger age (odds ratio 0.98 [95% CI 0.97 to 0.99]; p < 0.01), speaking English (OR 1.85 [95% CI 1.14 to 3.02]; p = 0.01) rather than Spanish (OR 0.27 [95% CI 0.17 to 0.45]; p < 0.01), seeking care for back or neck symptoms, (OR 3.84 [95% CI 2.60 to 5.66]; p < 0.01) and higher number of completed visits (OR 1.03 [95% CI 1.01 to 1.05]; p < 0.01) were associated with an increased likelihood of portal registration while living in Austin, Texas, USA (OR 0.68 [95% CI 0.53 to 0.87]; p < 0.01) and Del Valle, Texas, USA (OR 0.47 [95% CI 0.30 to 0.74]; p < 0.01) compared with Pflugerville, Texas, USA, or other cities, seeking care for upper extremity (OR 0.74 [95% CI 0.58 to 0.94]; p = 0.01) or lower extremity symptoms (OR 0.68 [95% CI 0.53 to 0.86]; p < 0.01), and greater symptoms of anxiety (GAD score) (OR 0.97 [95% CI 0.95 to 0.99]; p < 0.01) or depression (PHQ score) (OR 0.97 [95% CI 0.95 to 0.98]; p < 0.01) were associated with lower likelihood of registering for the portal. English language, city of residence, and seeking care for back or neck symptoms (due to insurance contracts) were all associated with higher socioeconomic status in our setting. CONCLUSIONS: The association of better mental and social health (financial, employment, housing and food security; connectedness) with registration in a communication portal directs us to be more intentional about efforts to specifically welcome disadvantaged people to participate in the portal and to study the impact and effectiveness of such efforts. LEVEL OF EVIDENCE: Level III, therapeutic study.

Factors Associated with a Second Opioid Prescription Fill in Total Knee Arthroplasty.

BACKGROUND: Total knee arthroplasty (TKA) creates a relatively large degree of nociception, making it a good setting to study variation in pain intensity and pain alleviation. The purpose of this study is to investigate factors associated with a second prescription of opioid medications within 30 days of primary TKA. METHODS: Using an insurance database, we studied 1372 people over a 6-year period with no mental health comorbidities including substance misuse and no comorbid pain illness at the time of TKA. Factors associated with a second prescription of opioid medication within 30 days of TKA were sought among patient demographics and the overall prescription morphine milligram equivalents. Patient and prescription-related risk factors were evaluated utilizing logistic relative risk regression. We reserved a year of data, 222 people, to evaluate the performance of the derived model. RESULTS: More than half the patients filled a second prescription for opioids within 30 days of TKA. Factors associated with a second prescription of opioid medication within 30 days of TKA included age (P < .01), current smoker (P = .01), and the total morphine milligram equivalents of the initial prescription (P < .01). Applied to the 222 people we reserved for validation, the model was 81% sensitive and 14% specific for a second prescription within 30 days, with a positive predictive value of 74%, and a negative predictive value of 20%. CONCLUSION: People that are given more opioids tend to request more opioids, but our model had limited diagnostic performance characteristics indicating that we are not accounting for the key factors associated with a second opioid prescription. Future studies might address undiagnosed patient social and mental health opportunities, factors known to associate with pain intensity and satisfaction with pain alleviation. LEVEL OF EVIDENCE: Diagnostic Level III.

Influenza Vaccination Is Not Associated with Increased Number of Visits for Shoulder Pain.

BACKGROUND: Shoulder injury from vaccination was approved for automatic compensation from the Vaccine Injury Compensation Program (VICP)-a federal government program started in 1988 to shield the manufacturers of childhood vaccines from liability. The approval was made on the basis of case reports rather than experimental evidence. This, combined with the addition of influenza vaccination to the VICP in 2005 (which broadened coverage to include adults) and other social factors, was associated with a rapid rise in the number of claims of shoulder injury from vaccination over the last decade, which now account for more than half of all claims to the VICP. Given the high prevalence of newly symptomatic sources of shoulder pain such as rotator cuff tendinopathy, combined with the high prevalence of annual influenza vaccinations, there is a substantial risk of overlap leading to the post hoc ergo propter hoc fallacy ("after this, therefore because of this") contributing to misdiagnosis and inappropriate management of patients that perceive injury from vaccination. Records of medical care after a large number of vaccinations have a good chance of detecting serious shoulder pathology, even it is uncommon, which would result in an increased prevalence of visits for shoulder problems and specific types of shoulder pathology. QUESTIONS/PURPOSES: Is there a difference in the proportion of visits for shoulder pain within 3 months before and after vaccination among students and faculty receiving an influenza vaccination in the shoulder? METHODS: We studied people who were vaccinated for influenza between 2009 and 2018 at a university health service. During the study period, a comprehensive billing database identified 24,206 influenza vaccinations administered to 12,870 people (median age 20 years, range 16-77; 57% women). We had 80% power to detect a 0.1% increase in the proportion of shoulder problems after vaccination compared with before vaccination. Visits with coded ICD-9 shoulder diagnoses were identified from the electronic medical record. We compared the proportion of shoulder evaluations within 3 months before and 3 months after vaccination. RESULTS: With the numbers available, the proportion of visits for shoulder problems were not different before (1.1% [52 of 4801]) and after vaccination (1% [40 of 3977], risk ratio 1.1 [95% CI 0.8 to 1.5]; p = 0.72). Among all vaccinations, 49% (11,834 of 24,206) were preceded or followed by an appointment within 3 months before (20% [4801 of 24,206]), after (16% [3977]), or both before and after (13% [3056]) vaccine administration, and 1.4% (170) of these visits were related to a shoulder issue. The most common reason for shoulder-related appointments was atraumatic shoulder pain (79% [134 of 170]). CONCLUSIONS: Shoulder symptoms sufficient to seek care are notably common, even among relatively young adults, and are not more common after vaccination. Although this does not rule out an important rare pathology specific to vaccination, it seems important to consider the potential harms of assuming, based largely on chronology, that persistent shoulder pain after vaccination-something expected to be common based merely on the anticipated frequency of overlap of vaccination and common shoulder problems-represents harm from vaccine. LEVEL OF EVIDENCE: Level III, therapeutic study.

Factors Associated with Requesting Magnetic Resonance Imaging during the Management of Glomus Tumors.

BACKGROUND: The characteristic clinical presentation of glomus tumors and the low negative predictive value of the magnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this study aimed to investigate whether MRI improved the management of glomus tumors. METHODS: In total, 87 patients with a histologically confirmed glomus tumor were treated over a 25-year period and analyzed retrospectively. Multivariable logistic regression analysis was used to evaluate the independent predictors of an MRI request during the management of glomus tumors. RESULTS: ccording to the results, the patients who were treated by orthopaedic surgeons were more likely to have an MRI during the management of a glomus tumor. CONCLUSION: The role of an MRI during the management of a glomus tumor is unclear. Orthopaedic surgeons are more likely to request an MRI. Furthermore, visible lesions with characteristic symptoms probably do not benefit from MRI. However, it may help to be sure that the highest-quality MRI is used with the best possible coil for the finger.

What Role Does Positive Psychology Play in Understanding Pain Intensity and Disability Among Patients with Hand and Upper Extremity Conditions?

BACKGROUND: A large body of research shows that psychologic distress and ineffective coping strategies substantially contribute to more severe pain and increased physical limitations among patients with orthopaedic disorders. However, little is known about the relationship between positive psychology (constructs that enable individuals to thrive and adapt to challenges) and pain and physical limitations in this population. QUESTIONS/PURPOSES: (1) Which positive-psychology factors (satisfaction with life, gratitude, coping through humor, resilience, mindfulness, and optimism) are independently associated with fewer upper-extremity physical limitations after controlling for the other clinical and demographic variables? (2) Which positive-psychology factors are independently associated with pain intensity after controlling for relevant clinical and demographic variables? METHODS: In a cross-sectional study, we recruited patients presenting for a scheduled appointment with an orthopaedic surgeon at a hand and upper-extremity clinic of a major urban academic medical center. Of 125 approached patients, 119 (44% men; mean age, 50 ± 17 years) met screening criteria and agreed to participate. Patients completed a clinical and demographic questionnaire, the Numerical Rating Scale to assess pain intensity, the Patient-reported Outcomes Measurement Information System (PROMIS) Upper Extremity Physical Function computerized adaptive test to assess physical limitations, and six measures assessing positive-psychology constructs: The Satisfaction with Life Scale, the Gratitude Questionnaire, the Coping Humor Scale, the Brief Resilience Scale, the Cognitive and Affective Mindfulness Scale-Revised, and the Life Orientation Test-Revised. We first examined bivariate associations among physical limitations, pain intensity, and all positive-psychology factors as well as demographic and clinical variables. All variables that demonstrated associations with physical limitations or pain intensity at p < 0.05 were included in two-stage multivariable hierarchical regression models. RESULTS: After controlling for the potentially confounding effects of prior surgical treatment and duration since pain onset (step1; R total = 0.306; F[7,103] = 6.50), the positive-psychology variables together explained an additional 15% (R change = 0.145, F change [5, 103] = 4.297, p = 0.001) of the variance in physical limitations. Among the positive-psychology variables tested, mindfulness was the only one associated with fewer physical limitations (ß = 0.228, t = 2.293, p = 0.024, 4% variance explained). No confounding demographic or clinical variables were found for pain intensity in bivariate analyses. All positive-psychology variables together explained 23% of the variance in pain intensity (R = 0.23; F[5,106] = 6.38, p < 0.001). Among the positive-psychology variables, satisfaction with life was the sole factor independently associated with higher intensity (ß = -0.237, t = -2.16, p = 0.033, 3% variance explained). CONCLUSIONS: Positive-psychology variables explained 15% of the variance in physical limitations and for 23% of the variance in pain intensity among patients with heterogenous upper extremity disorders within a hand and upper extremity practice. Of all positive-psychology factors, mindfulness and satisfaction with life were most important for physical limitations and pain intensity, respectively. As positive-psychology factors are more easily modifiable through skills-based interventions than pain and physical limitations, results suggest implementation of such interventions to potentially improve outcomes in this population. Skills-based interventions targeting mindfulness and satisfaction with life may be of particular benefit. LEVEL OF EVIDENCE: Level II, prognostic study.

What Is the Effect of Vitamin C on Finger Stiffness After Distal Radius Fracture? A Double-blind, Placebo-controlled Randomized Trial.

BACKGROUND: It is proposed that vitamin C administration can reduce disproportionate pain and stiffness after distal radius fracture; however, randomized trials that tested this hypothesis have had inconsistent results. QUESTIONS/PURPOSES: (1) Is administering vitamin C after distal radius fracture associated with better ROM, patient-reported upper extremity function, and pain scores? (2) What factors are associated with post-fracture finger stiffness and worse upper extremity function? METHODS: This is a double-blind, randomized, placebo-controlled, noncrossover study. Between August 2014 and July 2017, we approached 204 consecutive patients, of which 195 were eligible, and 134 chose to participate. Participants were randomized to receive once-daily 500 mg vitamin C (67 participants) or placebo (67 participants) within 2 weeks after distal radius fracture. All patients received usual care at the discretion of their surgeon. The mean age of participants was 49 ± 17 years, 99 patients (74%) were women, and 83 (62%) were treated nonoperatively. The primary outcome was the distance between the fingertip and distal palmar crease 6 weeks after fracture. This measure is easy to obtain and previously has been shown to correlate with aggregate ROM of all finger joints. The secondary outcomes were total active finger motion, total active thumb motion, upper extremity-specific limitations, and pain intensity.An a priori power analysis suggested 126 patients would provide 80% power to detect a difference of 2 cm (SD 4.0) fingertip distance to palmar crease with α set at 0.05 using a two-tailed Student's t-test. Accounting for 5% lost to followup, we included 134 patients.All analyses were intention-to-treat. Ten participants of the intervention group and five of the placebo group were lost to followup. Their missing data were addressed by multiple imputation, after which we performed linear regression analysis for our outcome variables. RESULTS: Administration of vitamin C was not associated with ROM, function, or pain scores at 6 weeks (distance to palmar crease: ß -0.23; 95% CI -1.7 to 1.2; p = 0.754; finger ROM: ß 4.9; 95% CI, -40 to 50; p = 0.829; thumb ROM: ß 0.98; 95% CI, -18 to 20; p = 0.918, Patient-Reported Outcomes Measurement Information System [PROMIS] score: ß 0.32; 95% CI, -2.6 to 3.2; p = 0.828; pain score: ß -0.62; 95% CI, -0.62 to 0.89; p = 0.729) nor at 6 months (PROMIS score: ß -0.21; 95% CI, -3.7 to 3.3; p = 0.904; pain score: ß 0.31; 95% CI, -0.74 to 1.4; p = 0.559). At 6 weeks, we found that more finger stiffness was mildly associated with greater age (ß -1.5; 95% CI, -2.8 to -0.083; p = 0.038). Thumb stiffness was mildly associated with greater age (ß -0.72; 95% CI, -1.3 to -0.18; p = 0.009) and strongly associated with operative treatment (ß -32; 95% CI, -50 to -13; p = 0.001). Greater pain interference was modestly associated with greater functional limitations at 6 weeks (ß -0.32; 95% CI, -0.52 to -0.12; p = 0.002) and 6 months (ß -0.36; 95% CI, -0.60 to -0.11; p = 0.004). CONCLUSIONS: Vitamin C does not seem to facilitate recovery after distal radius fracture, but amelioration of maladaptation to nociception (pain interference) merits greater attention. LEVEL OF EVIDENCE: Level I, therapeutic study.

The "July Effect" on Shoulder Arthroplasty: Are Complication Rates Higher at the Beginning of the Academic Year?

BACKGROUND: The "July effect" is a colloquialism asserting an increased rate of errors at the start of the academic year in teaching hospitals. This retrospective population-based study evaluated for the presence of the July effect in performing shoulder arthroplasty. METHODS: Using the Nationwide Inpatient Sample for 2002 through 2011, a total of 178,590 patients undergoing shoulder arthroplasty at academic medical centers were identified and separated into 2 groups: 1) patients admitted during July and 2) patients admitted between August and June. Multivariable logistic regression was used to identify associations with inpatient mortality and adverse events, blood transfusion, prolonged length of stay (>75th percentile) and non-routine discharge. RESULTS: After adjusting for patient, procedure, and hospital characteristics in multivariable modeling, admission in July was not associated with increased risk for inpatient mortality (OR 1.6) aggregate morbidity, blood transfusion, prolonged length of stay, and non-routine discharge. CONCLUSION: This nationwide database analysis shows that shoulder arthroplasty at academic medical centers is not associated with increased perioperative morbidity and resource utilization during the month of July.

What Is the Relationship of Fear Avoidance to Physical Function and Pain Intensity in Injured Athletes?

BACKGROUND: Fear avoidance can play a prominent role in maladaptive responses to an injury. In injured athletes, such pain-related fear or fear avoidance behavior may have a substantial influence on the recovery process. Specifically, it may explain why some are able to reach their preinjury abilities, whereas others are unable to return to sport. QUESTIONS/PURPOSES: (1) Is fear avoidance in athletes associated with decreased physical function after injury? (2) To what degree is fear avoidance associated with athletes' pain intensity? METHODS: In a cross-sectional study, we recruited injured athletes-defined as patients with sports-related injury, weekly engagement in sport activities, participation in competitive events as part of a team or club, self-identification as an athlete, and a desire to return to sport after recovery-from an orthopaedic sports medicine center at a major urban university hospital. Of 130 approached patients, 102 (84% men; mean ± SD age 25 ± 8.5 years) met the inclusion criteria. Participants completed a demographic questionnaire, the Athlete Fear Avoidance Questionnaire, which assesses injury-related fear and avoidance behavior specifically in an athletic population, the Pain Catastrophizing Scale, the Hospital Anxiety and Depression Scale, and two Patient-Reported Outcomes Measurement Information System measures: Physical Function Computerized Adaptive Testing (CAT) and Pain Intensity CAT. RESULTS: After controlling for age, injury region (upper versus lower extremity), catastrophic thinking, and emotional distress, we found that an increase in athletes' fear avoidance was associated with a decrease in physical function (b = -0.32; p = 0.002). The model explained 30% of the variation in physical function with 7.3% explained uniquely by fear avoidance. After controlling for initial appointment/followup, surgery for the current condition, multiple pain conditions, history of prior sport-related injury/surgery, pain medication prescription, catastrophic thinking, and emotional distress, athletes' fear avoidance was not associated with pain (b = -0.14; p = 0.249). The model explained 40% of the variation in pain intensity and pain catastrophizing (b = 0.30; p = 0.001) uniquely explained 7.1% of this variation. CONCLUSIONS: In injured athletes, fear avoidance is independently associated with decreased physical function, whereas pain catastrophizing is associated with high pain intensity. Both level of an athlete's fear avoidance and catastrophic thinking about pain should be accounted for in clinical interventions aimed at helping athletes improve recovery and return to sport. LEVEL OF EVIDENCE: Level II, prognostic study.

Night Splinting for Idiopathic Trigger Digits.

BACKGROUND: This study assessed nighttime splinting for 6 weeks as treatment for recent onset idiopathic trigger fingers. METHODS: Patients over 18 years with a Quinnell grade 1 or 2, idiopathic trigger finger or thumb causing symptoms for less than 3 months were eligible for a custom-made hand-based orthoplast night orthotic. Improvement of symptoms and/or resolution of triggering were recorded. Patients also completed the short version of the Disabilities of the Arm, Shoulder and Hand and a numerical rating scale for pain at the initial visit, after 6 to 8 weeks, and after 3 months. RESULTS: Thirty-four patients wore a night orthotic for at least 6 weeks. At final evaluation, there was a substantial reduction in disability and pain. Symptoms of triggering resolved completely in 18 patients (55%). Sixteen patients did not resolve their triggering after splinting and therefore underwent a steroid injection. CONCLUSION: Night splinting is a noninvasive treatment option for idiopathic trigger fingers/thumb with symptoms for less than 3 months.

The Effect of Priming With Questionnaire Content on Grip Strength in Patients With Hand and Upper Extremity Illness.

BACKGROUND: Grip strength is a performance-based measure of upper extremity function that might be influenced by priming (the influence of a response to a stimulus by exposure to another stimulus). This study addressed the influence of questionnaire content on performance measurements such as grip strength between patients who complete the standard Pain Catastrophizing Scale (PCS) compared with patients who complete a positively adjusted PCS. METHODS: Between June 2015 and August 2015, we enrolled 122 patients who presented to 3 hand surgeons at 3 outpatient offices. They were randomized to 2 groups: the control group, which completed the PCS, and the intervention group, which completed a positively phrased version of the PCS. Before and after completion of the questionnaire, we measured each patient's grip strength 3 times by alternating between hands. Two patients were excluded after participation. We calculated both the preintervention and postintervention mean and maximum grip strengths. RESULTS: There was no significant difference between groups on mean or maximum grip strength before completion of the questionnaires. There was a greater improvement in mean grip strength of both hands in the intervention group compared with the PCS group. This improvement was statistically significant in the affected hand. The maximum grip strength showed a statistically significant greater improvement in both hands in the positive PCS group compared with the control group. CONCLUSIONS: Positive priming through a questionnaire leads to an increase in mean and maximum grip strength when compared with the standard questionnaire that uses negative terms rather than positive.
