RESUMO
BACKGROUND: Psychological factors may impact recovery in patients undergoing treatment for shoulder complaints. The aim of this review is to systematically analyse the evidence for the effect of modifiable psychological factors (MPF) on outcome, for patients with musculoskeletal shoulder disorders undergoing conservative or surgical treatment. MPF refers to factors that may change with intervention. METHODS: This is a systematic literature review. Five databases searched (MEDLINE, CINAHL, Cochrane Library, Embase and PsycInfo), for longitudinal studies investigating the influence of MPF on prognosis of patients with shoulder disorders, all diagnoses, undergoing clinical interventions (conservative or surgical). Level of evidence was determined using Scottish Intercollegiate Guidelines Network (SIGN) methodology. Moderate and high quality evidence was included. We extracted all MPF, categorized constructs into the following domains: beliefs (self-efficacy, expectation of recovery), coping (catastrophizing, avoidant coping), and affect (depression, anxiety). We evaluated constructs for its predictive value of at least one outcome. Outcomes were informed by this review. Evidence was classified into three categories: evidence for, inconclusive evidence, and evidence against. RESULTS: Of 1170 references, 40 distinct publications based on 35 datasets were included (intervention type: 20 surgical; 20 conservative). Overall, 22 studies (20 cohort studies and 2 RCTs) were classified as high quality and 18 studies (16 cohort studies, 2 RCTs) were classified as moderate quality. Outcomes reported included pain, disability/function, perceived recovery, physical and mental health, and work status. Based on the review, of the psychological constructs explored, these data would suggest that expectation of recovery, catastrophizing, avoidant coping, depression, and anxiety may predict outcome for patients managed surgically. In patients undergoing conservative intervention the evidence was either against (catastrophizing, depression, anxiety) or inconclusive (self-efficacy, expectation of recovery, avoidant coping) for the predictive value of psychological factors on outcome. CONCLUSIONS: Five constructs were predictive of outcome for surgically managed patients. This suggests that implementing the biopsychosocial approach (i.e., preoperative screening, intervention by a trained clinician) may be advantageous for patients recommended for shoulder surgery,,. The same is not indicated for conservatively managed patients as no conclusive association of MPF with outcomes was noted. The importance of other MPF on outcome requires further investigation.

PURPOSE: Patient-reported outcome measures (PROM) are used to measure treatment efficacy in clinical trials. The impact of the choice of a PROM and the cut-off values for 'meaningful important differences' (MID) on the study results in patients with lumbar spinal stenosis (LSS) is unclear. OBJECTIVE: The objective is to study the consequences of applying different PROMs and values for MID for pain and disability on the proportions of patients with improvement. DESIGN: Prospective multi-center cohort study. METHODS: Proportions of patients with improvement using established MID cut-off values were calculated and compared for PROMs for pain and disability. RESULTS: 466 patients with LSS completed a baseline and 6-month follow-up assessment and were analyzed. Treatment modalities included surgery (65 %), epidural steroid injections (15 %), or conservative care (20 %). The prevalence of patients fulfilling the criteria for MID ranged from 40 to 70 % across all outcome measures and cut-offs. The agreement of the spinal stenosis outcome measure (SSM) symptom subscale with other pain scales, and the SSM function subscale with other function scales was fair to moderate (Cohen's κ value between 0.24 and 0.5). Disagreement in the assessment of MID (MID reported by patients in one scale but not the other) was found in at least one-third of the patients. CONCLUSION: The MID in outcome scores for this population varied from 40 to 70 %, depending on the measure or cut-off score used. Further, the disagreement between domain specific measures indicates that differences between studies may be also related to the choice of an outcome measures. An international consensus on the use and reporting of outcome measures in studies on lumbar spinal stenosis is needed.

Introduction: Older adults comprise a large portion of back pain (BP) sufferers but are under-represented in the literature. Patients over age 65 present with different clinical characteristics and psychosocial needs than younger patients. Therefore, recommended patient-centered outcomes for BP may not be relevant to older patients. Research question: What treatment outcomes are most important to adults over 65 years of age? Materials and methods: We queried older adults seeking treatment for BP using qualitative methods. Participants were asked about their goals and expectations of treatment in an audio-taped interview. Audiotapes were transcribed, coded and analyzed by the investigators. Using thematic analysis, main themes and constructs were extracted and interpreted by the investigators. From there we were able to generate hypotheses about what older patients want from spine treatment. Results: For all participants, age played a role in their treatment goals as a moderator or motivator. They were most concerned with returning to usual activities and preventing further physical limitations to maintain independence. Goals that reflect important outcomes such as increasing walking tolerance and improving balance were of particular importance. Confidence in the provider acted as a facilitator of goals. Discussion and conclusion: Unlike their younger cohorts, they did not emphasize work-related outcomes and pain relief. These findings can be tested in future quantitative studies and will help to develop protocols for outcomes assessment in older adults. This study is a first step towards understanding and improving the quality of care for older patients with back pain.
RESUMO
INTRODUCTION: Musculoskeletal injuries (MSIs) are a leading cause of separation from the U.S. Navy. Data have shown that several psychological responses to MSI are associated with treatment outcomes. Yellow flags are maladaptive psychological responses to injury and predict delayed recovery, whereas pink flags indicate resilience after MSI and are associated with good treatment outcomes. Identifying these factors in patients with MSI would permit early targeted care to address factors that may delay their readiness for deployment and enhance factors that support recovery. MATERIALS AND METHODS: Active duty service members with MSI who reported to physical therapy outpatient services at a naval hospital were recruited for the study. Yellow flags were assessed at baseline as part of a larger study. Participants completed the Fear Avoidance Beliefs Questionnaire (with two subscales, physical activity and work), the Pain Catastrophizing Scale, and the Hospital Anxiety and Depression Scale. Clinically relevant cut-off scores were used to indicate risk factors of delayed recovery. Pink flags were assessed with the Pain Self-Efficacy Questionnaire and a measure of positive outcome expectations for recovery. RESULTS: Two hundred and ninety participants responded to some or all of the questionnaires. Of these, 82% exceeded the cut-off scores on the physical activity subscale of the Fear Avoidance Beliefs Questionnaire, and 39% did so on the work subscale. Pain catastrophizing exceeded the cut-off in only 4.9% of the sample. Forty-three percent of these exceeded the cut-off for the anxiety subscale of the Hospital Anxiety and Depression Scale; 27% exceeded the cut-off on the depression subscale of the Hospital Anxiety and Depression Scale. Additionally, 54% endorsed scores greater than 40 on the Pain Self-Efficacy Questionnaire, and 53% endorsed a high score on the positive outcome expectations. CONCLUSIONS: A substantial portion of the sample endorsed elevated scores on one or more indicators of delayed recovery from MSI. Most participants showed a fear of physical activity, and approximately half reported pain-related distress (anxiety and depression). In addition, feelings of self-efficacy and positive outcome expectations of treatment were endorsed by only about half of the participants, indicating that the remaining half did not report adaptive responses to MSI. Early identification of these risk factors will allow for targeted treatment approaches that incorporate these yellow flags into treatment and support a psychologically informed approach to physical therapy. This approach is likely to reduce delayed recovery and improve deployment readiness.

INTRODUCTION: Musculoskeletal injuries (MSIs) pose a significant problem for active duty service members (ADSMs). MSIs may compromise readiness and are one of the main reasons for separation from the Navy and long-term disability. Implementation of optimal treatment strategies rests on understanding the characteristics of MSI complaints in a given population. This study reports on the frequency and nature of MSI complaints of ADSMs seeking care at a military treatment facility (MTF). MATERIALS AND METHODS: As part of a larger quasi-experimental study, data on MSIs from ADSMs reporting to an MTF were collected. Subjects completed a baseline questionnaire during an initial evaluation, including the self-reported MSIs for which participants were seeking care, time since onset, and other MSI comorbidities. RESULTS: Of the 289 respondents, 118 (41%) were female and 172 (59%) were male. The mean age was 33 years (SD = 8). The most frequently reported injury was low-back pain (n = 79, 27%), followed by knee pain (n = 60, 21%) and shoulder pain (n = 55, 19%). Thirty-four (12%) respondents reported injuries to the ankle or foot. The remaining respondents (21%) reported injuries to the neck, mid-back, arm or hand, hip, or other. Sixty-five (22%) reported an acute/subacute injury of less than 3 months, whereas 224 (78%) reported chronic injury >3 months. Furthermore, MSI comorbidities were reported by 233 (80%) of respondents with 128 of those reporting more than one. CONCLUSIONS: Back and knee injuries were most prevalent in ADSMs reporting an MSI at a Navy shore-based MTF. Shoulder injuries were also common. Of interest, 80% of ADSMs reported at least one MSI comorbidity and 80% reported chronic injury in this study. These rates are higher than those found in a previous study of ADSMs deployed on a carrier. This is notable because chronicity and multiple MSIs are obstacles to readiness. Our findings suggest that ADSMs reporting to shore-based facilities may be at higher risk for disability than their deployed counterparts. This information is important to the development of targeted care to improve readiness in this population.

INTRODUCTION: Musculoskeletal disorders (MSDs) are a primary cause of separation and long-term disability in active duty service members (ADSMs). Psychologically informed physical therapy (PiPT) is designed to identify and address modifiable psychological risk factors early in an MSD episode and has been proven effective in preventing chronicity in civilian populations. We developed a course to train military physical therapy (PT) personnel in PiPT for treating ADSM with MSD. This study tests the feasibility and effectiveness of our training. OBJECTIVE: Establish the feasibility of implementing PiPT and its effectiveness in the U.S. military. MATERIALS AND METHODS: An observational, prospective, comparative cohort study will test implementation and effectiveness. First, we will observe clinical outcomes in a cohort of ADSM with MSD receiving usual PT care at a military outpatient PT clinic. Next, we will train all PT staff in PiPT. Finally, PiPT will be implemented in a second cohort of ADSM. Data will be collected from each cohort at pre-treatment, fourth PT visit, 6 months post enrollment, and 12 months post enrollment. The primary outcomes are pain interference and psychological risk for chronicity. RESULTS AND CONCLUSIONS: Data collection is ongoing. Findings will identify the factors associated with PiPT outcomes in ADSM, inform the implementation of PiPT across health care settings, and allow us to document the prevalence of risk factors for chronicity in ADSM. Findings can help to prevent chronification from MSD, thereby reducing lost man-hours and enhancing military readiness, contribute to the development of a highly skilled workforce for the provision of health services to ADSM, and enhance the efficiency of health care delivery through optimal allocation of PT resources, resulting in significant cost savings for the military.

The aim of the pilot study was to evaluate a multidisciplinary program for nonspecific low back pain (NSLBP) at a major U.S. Navy base. In this single blinded randomized clinical trial, subjects were drawn from a larger, prospective cohort of active duty service members seeking care for NSLBP pain at a U.S. Navy Branch Medical Clinic. Outcome measures included return to work, self-reported pain, function, and psychological distress. Subjects were randomly allocated to one of two study arms: a multidisciplinary reconditioning program or the current standard of care for low back pain. The intervention lasted 4 weeks with a 12-week follow-up. Thirty-three subjects were enrolled. Subjects allocated to multidisciplinary care reported significantly lower perceived disability (p = 0.014) and less pain than those allocated to usual care at the end of the intervention period. All subjects returned to their usual duty following the conclusion of the intervention. The implementation of the intervention program was successful. Subjects in the multidisciplinary program showed a clinically significant improvement in the perception of disability compared to the usual care group. This is an important finding since perception of disability is associated with long-term functional outcome.

INTRODUCTION: This brief report describes the number and nature of cases of musculoskeletal pain and injury among sailors and marines presenting to the ship's physical therapist during recent, respective deployments of two U.S. Navy aircraft carriers. MATERIALS AND METHODS: The case definition for this study was cases of work-limiting medical complaints involving the musculoskeletal system presenting, or referred, to the ship's physical therapy services for evaluation and treatment. The population for this study was drawn from ship's company from two Nimitz class carriers on their respective deployments. Potential subjects were recruited at their index visit for their complaint. Participants completed a survey of their symptoms while at the ship's medical department. Data for analysis consist of counts of cases, body part affected, self-reported mechanism of injury, age, and gender of the subject. Data were analyzed by generating descriptive tables. RESULTS: One hundred ninety-seven cases were captured across the two carriers. Injury to the low back was the most frequent (34%), followed by shoulder (25%) and knee (15%). Twenty one cases (11%) were reported to be exacerbation of previous injuries and the rest new injuries. Of the 176 new injury cases, 93 (53%) were of an insidious onset and the remainder had a specific, identifiable onset. Of the 82 cases with a specific identifiable onset, 38 cases (46%) occurred during participation in sport and exercise activity on board ship, and the remainder of the cases occurred during the performance of duty-related work. None of the cases required evacuation off of the ship. CONCLUSION: Care should be used interpreting the results since participants were volunteers and a small proportion of eligible subjects chose not to participate in the study. Nevertheless, our data are generally consistent with other studies of musculoskeletal injury on board U.S. Navy ships and are useful for health care planning purposes and for planning for future studies that may take place on board U.S. Navy vessels. The novel and important finding of this study suggests that sports and exercise activity on board ship may warrant a new area of attention for safety.

BACKGROUND CONTEXT: Negative beliefs are known to influence treatment outcome in patients with spine pain (SP). The impact of positive beliefs is less clear. PURPOSE: We aimed to assess the influence of positive and negative beliefs on baseline and treatment responses in patients with SP. STUDY DESIGN/SETTING: A retrospective cross-sectional and longitudinal analysis of prospectively collected data of outpatient physical therapy patients with SP was carried out. Questionnaires administered before and during treatment included the STarT Back distress scale (negative beliefs), and expectation and self-efficacy questions (positive beliefs). PATIENT SAMPLE: Patients with SP with a baseline assessment and follow-up assessment comprised the study sample. OUTCOME MEASURE: Perceived disability was measured using the Oswestry Disability Index (ODI) or the Neck Disability Index (NDI). A clinical meaningful change (minimum clinically important difference [MCID]) was defined as decrease in ODI or NDI of ≥30%. METHODS: We used the Akaike Information Criterion from the first imputed dataset of the prediction model to select predictor variables. Prediction models were fitted to the outcome variables. RESULTS: In the cross-sectional analysis, 1,695 low back pain (LBP) episodes and 487 neck pain (NP) episodes were analyzed. STarT Back Screening Tool (SBST)-distress was positively associated with perceived disability in both LBP (beta 2.31, 95% confidence interval [CI] 1.75-2.88) and NP (beta 2.57, 95% CI 1.47-3.67). Lower self-efficacy was negatively associated with more perceived disability for LBP (beta 0.50, 95% CI 0.29-0.72) but not for NP, whereas less positive expectations was associated with more perceived disability in NP (beta 0.57, 95% CI 0.02-1.12) but not in LBP. In the longitudinal analysis, 607 LBP episodes (36%) and 176 (36%) NP episodes were included. SBST-distress did not predict treatment outcome in spine patients. In LBP, patients with a lower positive expectation were less likely to experience an MCID in perceived disability (odds ratio [OR] per point increase 0.89, 95% CI 0.83-0.96), and there was a similar trend in NP (OR per point increase 0.90, 95% CI 0.79-1.03). In patients with LBP, lower self-efficacy at baseline was associated with a higher likelihood that an MCID was achieved (OR per point increase 1.09, 95% CI 1.01-1.19). In NP, self-efficacy was not included in the final model. CONCLUSIONS: Our study demonstrates that both negative and positive beliefs are associated with perceptions of disability. However, in this study, only positive beliefs were associated with treatment outcome.

This study assesses the feasibility of training U.S. Navy Physical Therapy staff members (PT staff) aboard a U.S. Navy Aircraft Carrier in psychologically informed physical therapy (PiPT). Training was conducted prior to deployment over 3 d and included background information, skills development, and application in the form of role playing and case studies. During deployment, nine phone conferences were conducted to reinforce training, assess skills, and discuss implementation. PiPT knowledge was assessed by a written test and role-playing skills. The adoption of the training was determined by analysis of clinical notes and verbal responses of the PT staff during phone conferences. There were two PT staff members on the carrier. Both received passing knowledge test scores and demonstrated role-playing proficiency. Clinical note assessment and discussions during conference calls also indicated successful implementation. The feasibility of training Navy PT staff to implement PiPT was demonstrated. PT staff successfully translated training into practice. This is significant, since PiPT has the potential to limit attrition due to musculoskeletal injuries in Navy personnel. Factors believed to be associated with the success of the training include adoption of the PiPT model by PT staff and reinforcement of changes in clinical practice during deployment.

BACKGROUND: Expecting to recover from a musculoskeletal injury is associated with actual recovery. Expectations are potentially modifiable, although it is not well understood how injured people formulate expectations. A better understanding of how expectations are formulated may lead to better knowledge about how interventions might be implemented, what to intervene on, and when to intervene. OBJECTIVES: The objective of this study was to explore what "recovery" meant to participants, whether they expected to "recover," and how they formed these expectations. METHODS: This qualitative study used interpretive phenomenological analysis. Eighteen semistructured interviews were conducted with people seeking treatment for recent musculoskeletal injuries. RESULTS: Recovery was conceptualized as either (1) complete cessation of symptoms or pain-free return to function or (2) return to function despite residual symptoms. Expectations were driven by desire for a clear diagnosis, belief (or disbelief) in the clinician's prognosis, prior experiences, other people's experiences and attitudes, information from other sources such as the Internet, and a sense of self as resilient. CONCLUSIONS: Expectations appear to be embedded in both hopes and fears, suggesting that clinicians should address both when negotiating realistic goals and educating patients. This approach is particularly relevant for cases of nonspecific musculoskeletal pain, where diagnoses are unclear and treatment may not completely alleviate pain.

STUDY DESIGN: Systematic review. OBJECTIVE: The aim of this study was to assess the effect of catastrophizing on treatment efficacy and outcome in patients treated for low back pain. SUMMARY OF BACKGROUND DATA: Psychological factors including catastrophizing thoughts are thought to increase the risk for chronic low back pain. The influence of catastrophizing is debated. METHODS: In September 2012, the following databases were searched: BIOSIS, CINAHL, Cochrane Library, EMBASE, OTseeker, PeDRO, PsycINFO, MEDLINE, Scopus, and Web of Science. For 50 of 706 references, full text was assessed. Results based on 11 studies were included in this analysis. RESULTS: In the 11 studies, a total of 2269 patients were included. Seven studies were of good and 4 of moderate methodological quality. Heterogeneity in study settings, treatments, outcomes, and patient populations impeded meta-analysis. Catastrophizing at baseline was predictive for disability at follow-up in 4 studies and for pain in 2 studies. Three studies found no predictive effect of catastrophizing. A mediating effect was found in all studies (n = 5) assessing the impact of a decrease in catastrophizing during treatment. A greater decrease was associated with better outcome. Most studies that investigated the moderating effects on treatment efficacy found no effect (n = 5). However, most studies did not look for a direct interaction between the treatment and catastrophizing thoughts. No study investigated the influence of catastrophizing on work-related outcomes including return to work. CONCLUSION: Catastrophizing predicted degree of pain and disability and mediated treatment efficacy in most studies. The presence of catastrophizing should be considered in patients with persisting back pain. Limited evidence was found for the moderating effects on treatment efficacy. Future research should aim to clarify the role of catastrophizing as a moderator of outcome and investigate its importance for work-related outcomes. LEVEL OF EVIDENCE: 1.

BACKGROUND CONTEXT: Psychological factors including fear avoidance beliefs are believed to influence the development of chronic low back pain (LBP). PURPOSE: The purpose of this study was to determine the prognostic importance of fear avoidance beliefs as assessed by the Fear Avoidance Beliefs Questionnaire (FABQ) and the Tampa Scale of Kinesiophobia for clinically relevant outcomes in patients with nonspecific LBP. DESIGN/SETTING: The design of this study was a systematic review. METHODS: In October 2011, the following databases were searched: BIOSIS, CINAHL, Cochrane Library, Embase, OTSeeker, PeDRO, PsycInfo, PubMed/Medline, Scopus, and Web of Science. To ensure the completeness of the search, a hand search and a search of bibliographies was conducted and all relevant references included. A total of 2,031 references were retrieved, leaving 566 references after the removal of duplicates. For 53 references, the full-text was assessed and, finally, 21 studies were included in the analysis. RESULTS: The most convincing evidence was found supporting fear avoidance beliefs to be a prognostic factor for work-related outcomes in patients with subacute LBP (ie, 4 weeks-3 months of LBP). Four cohort studies, conducted by disability insurance companies in the United States, Canada, and Belgium, included 258 to 1,068 patients mostly with nonspecific LBP. These researchers found an increased risk for work-related outcomes (not returning to work, sick days) with elevated FABQ scores. The odds ratio (OR) ranged from 1.05 (95% confidence interval [CI] 1.02-1.09) to 4.64 (95% CI, 1.57-13.71). The highest OR was found when applying a high cutoff for FABQ Work subscale scores. This may indicate that the use of cutoff values increases the likelihood of positive findings. This issue requires further study. Fear avoidance beliefs in very acute LBP (<2 weeks) and chronic LBP (>3 months) was mostly not predictive. CONCLUSIONS: Evidence suggests that fear avoidance beliefs are prognostic for poor outcome in subacute LBP, and thus early treatment, including interventions to reduce fear avoidance beliefs, may avoid delayed recovery and chronicity.

BACKGROUND CONTEXT: Psychological factors including catastrophizing thoughts are believed to influence the development of chronic low back pain (LBP). PURPOSE: To assess the prognostic importance of catastrophizing as a coping strategy in patients with LBP. STUDY DESIGN: This is a systematic review. PATIENT SAMPLE: This study included patients with LBP. OUTCOME MEASURES: Work-related outcomes and perceived measures including return to work, pain, and disability. METHODS: In September 2012, the following databases were searched: BIOSIS, CINAHL, Cochrane Library, Embase, OTSeeker, PeDRO, PsycInfo, Medline, Scopus, and Web of Science. To ensure completeness of the search, a hand search and a search of bibliographies were conducted and all relevant references included. All observational studies investigating the prognostic value of catastrophizing in patients with LBP were eligible. Included were studies with 100 and more patients and follow-up of at least 3 months. Excluded were studies with poor methodological quality, short follow-up duration, and small sample size. RESULTS: A total of 1,473 references were retrieved, and 706 references remained after the removal of duplicates. For 77 references, the full text was assessed and 19 publications based on 16 studies were included. Of four studies that investigated work-related outcomes, two found catastrophizing to be associated with work status. Most studies that investigated self-reported outcome measures (n=8, 66%) found catastrophizing to be associated with pain and disability at follow-up in acute, subacute, and chronic LBP patients. In most studies that applied cutoff values, patients identified as high catastrophizers experienced a worse outcome compared with low catastrophizers (n=5, 83%). CONCLUSIONS: There is some evidence that catastrophizing as a coping strategy might lead to delayed recovery. The influence of catastrophizing in patients with LBP is not fully established and should be further investigated. Of particular importance is the establishment of cutoff levels for identifying patients at risk.

BACKGROUND CONTEXT: Psychological factors are believed to influence the development of chronic low back pain. To date, it is not known how fear-avoidance beliefs (FABs) influence the treatment efficacy in low back pain. PURPOSE: To summarize the evidence examining the influence of FABs measured with the Fear-Avoidance Belief Questionnaire or the Tampa Scale of Kinesiophobia on treatment outcomes in patients with low back pain. STUDY DESIGN/SETTING: This is a systematic review. PATIENT SAMPLE: Patients with low back pain. OUTCOME MEASURES: Work-related outcomes and perceived measures including return to work, pain, and disability. METHODS: In January 2013, the following databases were searched: BIOSIS, CINAHL, Cochrane Library, Embase, OTSeeker, PeDRO, PsycInfo, PubMed/Medline, Scopus, and Web of Science. A hand search of the six most often retrieved journals and a bibliography search completed the search. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: research studies that included patients with low back pain who participated in randomized controlled trials (RCTs) investigating nonoperative treatment efficacy. Out of 646 records, 78 articles were assessed in full text and 17 RCTs were included. Study quality was high in five studies and moderate in 12 studies. RESULTS: In patients with low back pain of up to 6 months duration, high FABs were associated with more pain and/or disability (4 RCTs) and less return to work (3 RCTs) (GRADE high-quality evidence, 831 patients vs. 322 in nonpredictive studies). A decrease in FAB values during treatment was associated with less pain and disability at follow-up (GRADE moderate evidence, 2 RCTs with moderate quality, 242 patients). Interventions that addressed FABs were more effective than control groups based on biomedical concepts (GRADE moderate evidence, 1,051 vs. 227 patients in studies without moderating effects). In chronic patients with LBP, the findings were less consistent. Two studies found baseline FABs to be associated with more pain and disability and less return to work (339 patients), whereas 3 others (832 patients) found none (GRADE low evidence). Heterogeneity of the studies impeded a pooling of the results. CONCLUSIONS: Evidence suggests that FABs are associated with poor treatment outcome in patients with LBP of less than 6 months, and thus early treatment, including interventions to reduce FABs, may avoid delayed recovery and chronicity. Patients with high FABs are more likely to improve when FABs are addressed in treatments than when these beliefs are ignored, and treatment strategies should be modified if FABs are present.

BACKGROUND CONTEXT: Musculoskeletal disorders of the spine in the US military account for the single largest proportion of the absence of sickness causes leading to early termination. We explored if selected psychological and physical factors were associated with poor outcome after episodes of low back pain (LBP). PURPOSE: To identify clinical, demographic, and psychological factors predictive of work duty status after a complaint of LBP. STUDY DESIGN: A prospective clinical cohort of US Navy personnel treated for LBP. PATIENT SAMPLE: Eligible cases were active duty US Navy or Marine Corps personnel presenting to an emergency clinic or primary care clinic with a complaint of LBP, where the index episode of LBP was no more than 12 weeks duration before enrollment. OUTCOME MEASURES: The subject's work status (full duty, light duty, sick in quarters [SIQ], limited duty, or medically released to full duty) was abstracted from the subject's electronic medical record at approximately 4 weeks and then again 12 weeks after study enrollment. Work status in this study population is assigned by a Navy health-care provider at the time of a clinical visit and based on the health-care provider's determination of medical fitness for duty. This study collapsed work status into two groups, "full duty" (consisting of "full duty" and "medically released to full duty") and "not at full duty" (consisting of "light duty," "SIQ," and "limited duty"). METHODS: Volunteers completed a baseline questionnaire consisting of recommended well-validated measures, including attitudes and beliefs about LBP and work (Fear-Avoidance Beliefs Questionnaire [FABQ] and the Tampa Scale of Kinesiophobia), distress (the Pain Catastrophizing Scale), clinical depression (The Center for Epidemiologic Studies Depression scale), a numeric pain intensity scale, self-perceived disability (Oswestry Disability Index), and general health status (12-Item Short Form Health Survey). Navy health-care providers conducted a back pain-specific medical evaluation. Associations are expressed as multivariate-adjusted prevalence ratios (PRs) estimated using Poisson regression. RESULTS: Two hundred fifty-three participants were enrolled. Work status outcome was collected for 239 participants. Predictors of "not at full duty" at 4 weeks after enrollment included having back pain for 4 weeks or less before study enrollment (PR, 2.69; 95% CI, 1.21-5.97) and increased FABQ Work subscale score (PR, 1.05; 95% CI, 1.01-1.08). The sole predictor of work status at 12 weeks after enrollment was increased FABQ Physical Activity (FABQ Physical) subscale score (PR=1.14; 95% CI, 1.00-1.30). CONCLUSIONS: The findings that fear-avoidance beliefs were predictive of subsequent work status among active duty service personnel in this study population (after adjusting for clinical, demographic, and psychological covariates) suggest the clinical utility of addressing these factors during treatment of back pain episodes in the military. These findings reflect the important role that psychological factors may play in the return to work process in an active duty military population.

STUDY DESIGN: A fully blocked experimental design using clinical vignettes to query primary care physicians on prescription for management of acute nonspecific low back pain. OBJECTIVE: To identify how nonclinical patient factors, specifically sex, patient presentation, and socioeconomic status, influence physician treatment recommendations for assessing and treating acute nonspecific low back pain. SUMMARY OF BACKGROUND DATA: Adherence to evidence-based practice guidelines for nonspecific low back pain remains inconsistent. Therefore, it is important to understand what factors guide physician management of these cases. METHODS: One vignette and questionnaire was distributed to primary care and emergency department clinical physicians during meetings at five teaching hospitals. The questionnaire asked for diagnostic and treatment recommendations including specific tests, medications, therapeutic procedures, activity, referral to other services, and patient education for the case represented in the vignette. RESULTS: Subjects included 284 physicians and approximately 75% had less than 5 years of clinical practice experience. Multivariate logistic regression showed seven significant associations of patient factors with treatment recommendations for acute nonspecific low back pain (one sex, two socioeconomic status, and four patient presentation; P < 0.05). CONCLUSION: All three assessed nonclinical factors influenced physician decisions regarding diagnostic and treatment recommendations for acute nonspecific low back pain. Patient presentation, suggestive of a patient's emotional state, was shown to be the most influential.

BACKGROUND: Job stress has been associated with poor outcomes. In focus groups and small-sample surveys, physical therapists have reported high levels of job stress. Studies of job stress in physical therapy with larger samples are needed. OBJECTIVE: The purposes of this study were: (1) to determine the levels of psychological job demands and job control reported by physical therapists in a national sample, (2) to compare those levels with national norms, and (3) to determine whether high demands, low control, or a combination of both (job strain) increases the risk for turnover or work-related pain. DESIGN: This was a prospective cohort study with a 1-year follow-up period. METHODS: Participants were randomly selected members of the American Physical Therapy Association (n=882). Exposure assessments included the Job Content Questionnaire (JCQ), a commonly used instrument for evaluation of the psychosocial work environment. Outcomes included job turnover and work-related musculoskeletal disorders. RESULTS: Compared with national averages, the physical therapists reported moderate job demands and high levels of job control. About 16% of the therapists reported changing jobs during follow-up. Risk factors for turnover included high job demands, low job control, job strain, female sex, and younger age. More than one half of the therapists reported work-related pain. Risk factors for work-related pain included low job control and job strain. LIMITATIONS: The JCQ measures only limited dimensions of the psychosocial work environment. All data were self-reported and subject to associated bias. CONCLUSIONS: Physical therapists' views of their work environments were positive, including moderate levels of demands and high levels of control. Those therapists with high levels of demands and low levels of control, however, were at increased risk for both turnover and work-related pain. Physical therapists should consider the psychosocial work environment, along with other factors, when choosing a job.
