To What Degree do Shoulder Outcome Instruments Reflect Patients' Psychologic Distress?
ABSTRACT BACKGROUND: Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores. QUESTIONS/PURPOSES: We asked (1) to what degree shoulder outcome instruments reflect patients' psychologic distress, and (2) whether patients who are strongly affected by psychologic distress can be identified. METHODS: We prospectively evaluated 119 patients with chronic shoulder pain caused by degenerative or inflammatory disorders using the Constant-Murley scale, Simple Shoulder Test (SST), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. To evaluate psychologic distress, we measured depression using the Center for Epidemiologic Studies-Depression (CES-D) scale and pain anxiety using the Pain Anxiety Symptom Scale (PASS). Demographic and clinical parameters, such as pain scores, ROM, and abduction strength, also were measured. We then assessed the relative contributions made by psychologic distress and other clinical parameters to the quantitative ratings of the three shoulder outcome instruments. RESULTS: Quantitative ratings of shoulder outcome instruments correlated differently with psychologic distress. Constant-Murley scores did not correlate with psychologic measures, whereas SST scores correlated with PASS (r = 0.32) and DASH scores correlated with PASS and CES-D (r = 0.36 and r = 0.32). Psychologic distress contributed to worsening SST and DASH scores but not to Constant-Murley scores. DASH scores were more strongly influenced by pain anxiety and depression than the other two outcome instruments. CONCLUSIONS: Shoulder outcome measures reflected different psychologic aspects of illness behavior, and the contributions made by psychologic distress to different shoulder outcome instruments apparently differed. Physicians should select and interpret the findings of shoulder outcome instruments properly by considering their psychologic implications. LEVEL OF EVIDENCE: Level II, prognostic study.

ABSTRACT: Musculoskeletal disorders substantially impacts physical activity, mental state, and quality of life (QOL). Generally, comprehensive assessment of upper limb function requires measures of impairment or disability as well as health-related quality of life. A growing number of outcome instrument have been introduced to evaluate upper limb function and disability, and these measures can be categorized as patient- or clinician-based, and as condition specific or general health-related QOL evaluations. The upper limb outcome instruments reviewed in this article assess different aspect of upper limb conditions, and the measures are affected by differences in cultural, psychological, and gender aspect of illness perception and behavior. Therefore, physician should select/interpret the outcome instruments addressing their primary purpose of research. Information about regional instruments for upper limb condition and health-related QOL in upper limb disorder may help us in decision-making for treatment priority or in interpretation of the treatment outcomes.08/2013; 9(4):400-405.

ABSTRACT: This study investigates the neck/shoulder pain (NSP) and low back pain (LBP) among current high school students in Shanghai and explores the relationship between these pains and their possible influences, including digital products, physical activity, and psychological status. An anonymous self-assessment was administered to 3,600 students across 30 high schools in Shanghai. This questionnaire examined the prevalence of NSP and LBP and the level of physical activity as well as the use of mobile phones, personal computers (PC) and tablet computers (Tablet). The CES-D (Center for Epidemiological Studies Depression) scale was also included in the survey. The survey data were analyzed using the chi-square test, univariate logistic analyses and a multivariate logistic regression model. Three thousand sixteen valid questionnaires were received including 1,460 (48.41%) from male respondents and 1,556 (51.59%) from female respondents. The high school students in this study showed NSP and LBP rates of 40.8% and 33.1%, respectively, and the prevalence of both influenced by the student's grade, use of digital products, and mental status; these factors affected the rates of NSP and LBP to varying degrees. The multivariate logistic regression analysis revealed that Gender, grade, soreness after exercise, PC using habits, tablet use, sitting time after school and academic stress entered the final model of NSP, while the final model of LBP consisted of gender, grade, soreness after exercise, PC using habits, mobile phone use, sitting time after school, academic stress and CES-D score. High school students in Shanghai showed high prevalence of NSP and LBP that were closely related to multiple factors. Appropriate interventions should be implemented to reduce the occurrences of NSP and LBP.PLoS ONE 10/2013; 8(10):e78109. DOI:10.1371/journal.pone.0078109 · 3.53 Impact Factor

ABSTRACT: In several areas of orthopaedics, including spine and upper extremity surgery, patients with greater levels of psychologic distress report worse self-assessments of pain and function than patients who are not distressed. This effect can lead to lower than expected baseline scores on common patient-reported outcome scales, even those not traditionally considered to have a psychologic component. The purposes of this study were to determine (1) the association of psychologic distress and baseline modified Harris hip scores and Hip Outcome Scores in patients undergoing hip arthroscopy; and (2) whether psychologic distress would remain a significant negative predictor of baseline hip scores when other clinical variables such as age, sex, BMI, smoking status, and American Society of Anesthesiologists (ASA) classification were controlled. One hundred forty-seven patients at one center were prospectively enrolled when they scheduled hip arthroscopy to treat painful femoroacetabular impingement. Before surgery, psychologic distress was quantified using the Distress Risk Assessment Method questionnaire. Patients also completed baseline self-assessments of hip pain and function including the modified Harris hip score and the Hip Outcome Score. Age, sex, BMI, smoking status, and ASA classification were recorded for each patient. Bivariate correlations and multivariate regression models were used to assess the effect of psychologic distress on patient self-assessment of hip pain and function. Patients with distress reported significantly lower baseline modified Harris hip scores (58 versus 67, p = 0.001), Hip Outcome Score-Activities of Daily Living scores (62 versus 72, p = 0.002), and Hip Outcome Score-Sports scores (36 versus 47, p = 0.02). Distress remained significantly associated with lower baseline modified Harris hip (p = 0.006), Hip Outcome Score-Activities of Daily Living (p = 0.005), and Hip Outcome Score-Sports scores (p = 0.017) when age, sex, BMI, smoking status, and ASA classification were controlled for in the multivariate model. Practitioners should recognize that psychologic distress has a negative correlation with baseline patient self-assessment using the modified Harris hip score and the Hip Outcome Scores, scales not previously described to correlate with psychologic distress. Longitudinal followup is warranted to clarify the relationship between distress and self-perceived disability and the effect of distress on postoperative outcomes in patients having hip arthroscopy.
