Background
Chest pain is a high-risk emergency department (ED) chief complaint; the majority of clinical resources are directed toward detecting and treating cardiopulmonary emergencies. However, at follow-up, 80%–95% of these patients have only a symptom-based diagnosis; a large number have undiagnosed anxiety disorders.Objective
Our aim was to measure the frequency of self-identified stress or anxiety among chest pain patients, and compare their pretest probabilities, care processes, and outcomes.Methods
Patients were divided into two groups: explicitly self-reported anxiety and stress or not at 90-day follow-up, then compared on several variables: ultralow (<2.5%) pretest probability, outcome rates for acute coronary syndrome (ACS) and pulmonary embolism (PE), radiation exposure, total costs at 30 days, and 90-day recidivism.Results
Eight hundred and forty-five patients were studied. Sixty-seven (8%) explicitly attributed their chest pain to “stress” or “anxiety”; their mean ACS pretest probability was 4% (95% confidence interval 2.9%–5.7%) and 49% (33/67) had ultralow pretest probability (0/33 with ACS or PE). None (0/67) were diagnosed with anxiety. Seven hundred and seventy-eight did not report stress or anxiety and, of these, 52% (403/778) had ultralow ACS pretest probability. Only one patient (0.2%; 1/403) was diagnosed with ACS and one patient (0.4%; 1/268) was diagnosed with PE. Patients with self-reported anxiety had similar radiation exposure, associated costs, and nearly identical (25.4% vs. 25.7%) ED recidivism to patients without reported anxiety.Conclusions
Without prompting, 8% of patients self-identified “stress” or “anxiety” as the etiology for their chest pain. Most had low pretest probability, were over-investigated for ACS and PE, and not investigated for anxiety syndromes. 相似文献2.
Background
Ideally, high-stakes examinations assess 1 dimension of medical knowledge to produce precise estimates of a candidate’s performance. It has not been reported whether the American Board of Physical Medicine and Rehabilitation Part 1 Certification Examination (ABPMR-CE-1) is unidimensional or not.Objective
To examine the ABPMR-CE-1 to measure how many dimensions it assesses.Design
Retrospective observational study.Setting
We assessed examination results from the 2015 ABPMR-CE-1.Participants
A total of 489 deidentified candidates taking the 2015 ABPMR-CE-1.Methods
A 1-parameter Item Response Theory (IRT) measurement model was utilized. A Principal Components Analysis (PCA) of standardized residual correlations was used to detect multidimensionality.Main Outcome Measure
Number of primary dimensions reflected in the 325 test questions.Results
The results of the dimensionality analysis indicated that the ABPMR-CE-1 examination is highly unidimensional from a psychometric perspective. Expert content review of the substantive content of small contrasting clusters of questions provided additional assurance of the unidimensional nature of the examination.Conclusions
The ABPMR-CE-1 appears indeed to measure a single construct, which suggests a sound structure of the examination. It closely approximates the assumption of statistical unidimensionality.Level of Evidence

Background
Stroke is a primary cause of death and disability in upper-middle–income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region.Objective
To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia.Design
Cross-sectional study.Setting
The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia.Participants
Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50).Methods
Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnairesMain Outcome Measurements
Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke.Results
Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls.Conclusions
This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues.Level of Evidence

Background
A significant proportion of burn injury patients are admitted to inpatient rehabilitation facilities (IRFs). There is increasing interest in the use of functional variables, such as cognition, in predicting IRF outcomes. Cognitive impairment is an important cause of disability in the burn injury population, yet its relationship to IRF outcomes has not been studied.Objective
To assess how cognitive function affects rehabilitation outcomes in the burn injury population.Design
Retrospective study.Setting
Inpatient rehabilitation facilities in the United States.Participants
A total of 5347 adults admitted to an IRF with burn injury between 2002 and 2011.Methods or Interventions
Multivariable regression was used to model rehabilitation outcome measures, using the cognitive domain of the Functional Independence Measure (FIM) instrument as the independent variable and controlling for demographic, medical, and facility covariates.Main Outcome Measurements
FIM total gain, readmission to an acute care setting at any time during inpatient rehabilitation, readmission to an acute care setting in the first 3 days of IRF admission, rate of discharge to the community setting, and length of stay efficiency.Results
Cognitive FIM total at admission was a significant predictor of FIM total gain, length of stay efficiency, and acute readmission at 3 days (P < .05). Cognitive FIM total scores did not have an impact on acute care readmission rate or discharge to the community setting.Conclusions
Cognitive status may be an important predictor of rehabilitation outcomes in the burn injury population. Future work is needed to further examine the impact of specific cognitive interventions on rehabilitation outcomes in this population.Level of Evidence

Background
There is a growing interest in the use of biologic agents such as platelet-rich plasma and mesenchymal stem/stromal cells to treat musculoskeletal injuries, including meniscal tears. Although previous research has documented the role of diagnostic ultrasound to evaluate meniscal tears, sonographically guided (SG) techniques to specifically deliver therapeutic agents into the meniscus have not been described.Objective
To describe and validate SG injection techniques for the body and posterior horn of the medial and lateral meniscus.Design
Prospective, cadaveric laboratory investigation.Setting
Academic institution procedural skills laboratory.Subjects
Five unenbalmed cadaveric knee-ankle-foot specimens from 5 donors (3 female and 2 male) ages 33-92 years (mean age 74 years) with body mass indices of 21.1-32.4 kg/m2 (mean 24.1 kg/m2).Methods
A single, experienced operator completed SG injections into the bodies and posterior horns of the medial and lateral menisci of 5 unenbalmed cadaveric knees using colored latex and a 22-gauge, 38-mm needle. After injection, coinvestigators dissected each specimen to assess latex distribution within the menisci and identify injury to intra-articular and periarticular structures.Main Outcome Measures
Latex location within the target region of meniscus (accurate/inaccurate), and iatrogenic injury to “at risk” intra- and periarticular structures (present/absent).Results
Seventeen of 20 injections were accurate. Two of 3 inaccurate injections infiltrated the posterior horn of the medial meniscus instead of the targeted meniscal body. One inaccurate lateral meniscus injection did not contain latex despite sonographically accurate needle placement. No specimen exhibited injury to regional neurovascular structures or intra-articular hyaline cartilage.Conclusions
SG meniscus injections are feasible and can accurately and safely deliver injectates such as regenerative agents into bodies and posterior horns of the medial and lateral menisci. The role of SG intrameniscal injections in the treatment of patients with degenerative and traumatic meniscal disorders warrants further exploration.Level of Evidence

Background
ST-elevation myocardial infarction (STEMI) leading to cardiac arrest is an exceptionally rare occurrence in young adults. Those affected tend to abuse sympathomimetic drugs, have strong family histories, or have a significant burden of cardiac risk factors. Another uncommon cause of STEMI is coronary artery dissection, which overwhelmingly affects middle- and older-aged women with few cardiac risk factors.Case Report
A 22-year-old athlete with no medical history was admitted to our institution post–cardiac arrest with an anterior STEMI and concomitant right coronary dissection. To our knowledge, this represents the first documented case of these simultaneous pathologies in a young cardiac arrest survivor.Why Should an Emergency Physician Be Aware of This?
Myocardial infarction is rare in young adults, and a diverse range of etiologies must be considered promptly to prevent delays in time-sensitive therapies, such as antiplatelet agents and revascularization. The emergency physician is most often the first point of contact in patients with acute coronary syndromes, and the failure to recognize it in young adults threatens them with premature death and potentially life-long disability. 相似文献7.

Background
Left ventricular assist devices (LVADs) have become an increasingly popular and effective means for treating advanced heart failure. LVAD implantation requires extensive surgery and postoperative rehabilitation. The Functional Independence Measure (FIM) has been used to quantify functional gains in numerous patient populations, including those with stroke and spinal cord injury. This study investigated functional improvements in patients undergoing LVAD implantation using the FIM score.Objective
To assess functional improvements in patients with advanced heart failure who underwent LVAD implantation.Design
Retrospective.Setting
Inpatient rehabilitation unit.Subjects
Ninety consecutive patients who received acute inpatient rehabilitation after continuous flow LVAD implantation.Methods
Demographic, laboratory, and functional outcomes data including inpatient rehabilitation unit (IRU) length of stay (LOS), discharge disposition, and FIM score were collected for all patients. Paired t-tests were used to assess change in functional measures and laboratory data.Main Outcome Measures
Primary outcome measures included FIM gain, FIM efficiency, discharge disposition, rates of readmission after discharge from rehabilitation, and LOS in the rehabilitation unit.Results
The FIM gain was statistically significant at 28.4 ± 12.3 (P < .001) and compared favorably with benchmarks for mean FIM gains at our facility (26.4), regionally (21.5), and nationally (22.7) for patients admitted to IRUs with a cardiac diagnosis. FIM efficiency (FIM gain/IRU LOS) was 1.9 ± 1.0 compared with the mean FIM efficiency at our facility (2.2), regionally (2.1), and nationally (2.2). Seventy-four percent (n = 67) of patients were discharged directly home after inpatient rehabilitation, 17% (n = 16) were readmitted to the acute hospital service, and 8% (n = 7) required additional rehabilitation at a subacute rehabilitation facility. The IRU LOS was 16.2 ± 6.9 days.Conclusions
Our study indicates that most patients with an LVAD achieve clinically meaningful functional gains from acute inpatient rehabilitation, with the majority of patients being discharged home. Further studies need to be performed to analyze clinical outcomes after acute inpatient rehabilitation.Level of Evidence

Objective
To examine how patient satisfaction with care coordination and quality and access to medical care influence functional improvement or deterioration (activity limitation stage transitions), institutionalization, or death among older adults.Design
National representative sample with 2-year follow-up.Setting
Medicare Current Beneficiary Survey from calendar years 2001 to 2008.Participants
Community-dwelling adults (N=23,470) aged ≥65 years followed for 2 years.Interventions
Not applicable.Main Outcome Measures
A multinomial logistic regression model taking into account the complex survey design was used to examine the association between patient satisfaction with care coordination and quality and patient satisfaction with access to medical care and activities of daily living (ADL) stage transitions, institutionalization, or death after 2 years, adjusting for baseline socioeconomics and health-related characteristics.Results
Out of 23,470 Medicare beneficiaries, 14,979 (63.8% weighted) remained stable in ADL stage, 2508 (10.7% weighted) improved, 3210 (13.3% weighted) deteriorated, 582 (2.5% weighted) were institutionalized, and 2281 (9.7% weighted) died. Beneficiaries who were in the top quartile of satisfaction with care coordination and quality were less likely to be institutionalized (adjusted relative risk ratio [RRR], .68; 95% confidence interval [CI], .54–.86). Beneficiaries who were in the top quartile of satisfaction with access to medical care were less likely to functionally deteriorate (adjusted RRR, .87; 95% CI, .79–.97), be institutionalized (adjusted RRR, .72; 95% CI, .56–.92), or die (adjusted RRR, .86; 95% CI, .75–.98).Conclusions
Knowledge of patient satisfaction with medical care and risk of functional deterioration may be helpful for monitoring and addressing disability-related health care disparities and the effect of ongoing policy changes among Medicare beneficiaries. 相似文献10.

Background
Theoretically, patients with only one functional arm secondary to contralateral amputation or paralysis will subject their only functional upper extremity to increased loads. This could become an issue after reverse shoulder arthroplasty (RSA). However, there are no reported data on the implant survival or function for patients with a nonfunctional contralateral upper extremity.Objective
To report the outcomes of RSA in patients with contralateral upper extremity amputation or paralysis.Design
Retrospective case series.Setting
Tertiary university hospital.Patients
All patients who underwent RSA between January 2004 and December 2013.Methods
Of 1335 RSA procedures performed, 5 patients had a minimum 2-year follow-up and nonfunctional contralateral upper extremity. There were 3 men and 2 women, with a mean (standard deviation) age and length of follow-up of 72.4 (7.5) years and 56.4 (24-132) months. Two of the patients had a contralateral upper extremity amputation, and the other 3 had contralateral upper extremity paralysis as a result of stroke, traumatic brain injury, and traumatic brachial plexus injury at birth.Main Outcomes
Pain, range of motion, functional scores (Simple Shoulder Test, American Shoulder and Elbow Society and Quick-Disability of the Arm, Shoulder and Hand), satisfaction, complications/reoperations, and radiographic loosening.Results
RSA resulted in substantial improvement in pain (P = .008), forward flexion (P = .02), and external range of motion (P = .01). The mean (standard deviation) Simple Shoulder Test, American Shoulder and Elbow Society, and Quick-Disability of the Arm, Shoulder, and Hand scores were 9.8 (1.3), 82 (13), and 17.8 (13.4), respectively. The results were excellent in 3, satisfactory in 1, and unsatisfactory in 1 patient (due only to external rotation limited to 10°). Subjectively, all 5 patients felt greatly improved and stated they would undergo RSA again. There were no complications or reoperations. There were no shoulders with component loosening.Conclusions
RSA seems to be a safe, effective, and successful surgical procedure for patients with a nonfunctional contralateral upper extremity. Studies with larger sample sizes and longer follow-up will hopefully validate the present findings.Level of Evidence

Background
OnabotulinumtoxinA is approved for the treatment of upper and lower limb spasticity in adults. Guidance on common postures and onabotulinumtoxinA injection paradigms for upper limb spasticity has been developed via a Delphi Panel; however, similar guidance for lower limb spasticity has not been established.Objective
To define a clinically recommended treatment paradigm for the use of onabotulinumtoxinA for each common posture among patients with poststroke lower limb spasticity (PSLLS) and to identify the most common PSLLS aggregate postures.Design
Clinical experts provided insight regarding onabotulinumtoxinA treatment for PSLLS using an adaptation of the Delphi consensus process.Setting
Delphi panel.Participants
Ten expert clinicians in neurology and physical medicine and rehabilitation who treat PSLLS.Methods
A minimum of 2 rounds of anonymous voting occurred for each recommendation until consensus was reached (≥66% agreement). The first round was conducted via a survey; the second round was an in-person meeting.Main Outcome Measurements
Reached consensus on muscle selection for injection, overall and per-muscle dose of onabotulinumtoxinA, number of injection sites/muscle, onabotulinumtoxinA dilution, and use of localization techniques. The most common PSLLS postures were reviewed. Recommendations were tailored toward injectors with less experience.Results
Consensus was reached on targeted subsets of muscles for each posture. Doses ranged from 20 to 150 U for individual muscles and 50 to 300 U for limb postures. OnabotulinumtoxinA dilution 50 U/mL (2:1 ratio) was considered most appropriate but varied based on muscles selected (range, 2:1-4:1). Experts agreed that localization techniques for muscle identification during injection for all postures would be useful. For suboptimal response to injection, all panel members would increase the dose, and the majority (89%) would increase the number of treated muscles. The panel identified 3 common aggregating lower limb postures: (1) equinovarus foot and flexed toes; (2) extended knee and plantar flexed foot/ankle; and (3) plantar flexed foot/ankle and flexed toes. The recommended starting doses for each aggregate posture were 400 U, 400 U, and 300 U, respectively.Conclusion
The modified Delphi panel process provided consensus on common muscles and corresponding onabotulinumtoxinA treatment paradigms for postures associated with PSLLS that can be used for guidance in optimizing care delivery.Level of Evidence

Background
As our population ages, neurogenic claudication (NC) from central canal stenosis of the lumbar spine is becoming an increasingly common condition. Studies have been undertaken to assess the efficacy of caudal, interlaminar, or unilateral transforaminal epidural injections, but bilateral transforaminal epidural injections (BTESIs) have not been evaluated to date.Objective
To assess the therapeutic value and long-term effects of fluoroscope-guided BTESIs in patients with NC from degenerative lumbar spinal stenosis (DLSS) of the central spinal canal.Design
Case series.Setting
Single institution spine clinic.Patients
Twenty-six adults between the ages of 40 and 90 years with a diagnosis of DLSS and a history of subacute or chronic NC.Methods/Interventions
Patients meeting inclusion criteria received fluoroscope-guided BTESI of local anesthetic and steroid at the level immediately below the most stenotic level. Patient self-reported pain level, activity level, and overall satisfaction were recorded by telephone interview at 1, 3, and 6 months after injection by an independent observer.Main Outcome Measures
Pain score and Swiss Spinal Stenosis score at baseline, 1, 3, and 6 months.Results
Of the 22 participants eligible for analysis, 20, 19, and 18 had follow-up data available at 1, 3, and 6 months, respectively. Reduction in numeric pain scale score of at least 50% was noted in 30% of participants at 1 month, 53% at 3 months, and 44% at 6 months. Swiss Spinal Stenosis subscale scores indicated a significant reduction in the proportion of participants reporting the presence of severe pain in the back, buttocks, and legs (particularly the back or buttocks) at 1, 3, and 6 months of follow-up compared with baseline (P < .05). The proportion of participants reporting severe weakness in the legs or feet also decreased after injection and was statistically significant at 3 months of follow-up (P = .04).Conclusions
Fluoroscope-guided BTESI was moderately effective in reducing pain, improving function, and achieving patient satisfaction in patients with NC from DLSS at the central spinal canal in this clinical case series.Level of Evidence

Background
Patients have expressed concern about undergoing procedures involving trainees, even with direct attending physician supervision. Little literature has examined the effect of trainee involvement on patient outcomes.Objective
We aimed to evaluate the effect of trainee involvement on patient complications, immediate pain reduction, and fluoroscopic time for different fluoroscopic injection types.Design
Retrospective review.Setting
Four academic outpatient institutions with Accreditation Council for Graduate Medical Education (ACGME)?accredited residency (physical medicine and rehabilitation, or anesthesiology) or fellowship (sports medicine or pain medicine) programs from 2000 to 2015.Patients
All patients receiving fluoroscopically guided hip (HI), sacroiliac joint (SIJI), transforaminal epidural (TFEI), and/or interlaminar epidural injections (ILEI, performed at only 1 institution).Methods
Outcome measures were examined based on the presence or absence of a trainee during the procedure.Main Outcome Measurements
The primary outcome was the number of immediate complications, with secondary outcomes being fluoroscopic time per injection (FTPI) and immediate numeric rating scale percentage improvement.Results
Trainees were involved in 67.0% of all injections (N = 7,833). Complication rates or improvements in numeric rating scale scores showed no significant differences with trainee involvement for any injection type (P > .05). Trainee involvement was associated with increased FTPI for ILEIs (18.2 ± 10.1 seconds with trainees versus 15.1 ± 8.5 seconds without trainees, P < .001), but not for HIs (P = .60) or SIJIs (P = .51). Trainee involvement with TFEIs was dependent on institution for outcome with respect to FTPI (P < .001), with 28.1 ± 17.9 seconds with trainees and 32.1 ± 22.1 seconds without trainees (P = 0.51).Conclusions
This large multicenter study of academic institutions demonstrates that trainee involvement in fluoroscopically guided injections does not affect immediate patient complications or pain improvement. Trainee involvement does not increase fluoroscopic time for most injections, although there is an institutional difference seen. This study supports the notion that appropriate trainee supervision likely does not compromise patient safety for fluoroscopically guided injections.Level of Evidence

Objectives
To examine the effect of experimental knee pain on perceived knee pain and gait patterns and to examine the efficacy of transcutaneous electrical nerve stimulation (TENS) on perceived knee pain and pain-induced knee gait mechanics.Design
Crossover trial.Setting
Biomechanics laboratory.Participants
Recreationally active, individuals without musculoskeletal pain aged 18 to 35 years (N=30).Interventions
Thirty able-bodied individuals were assigned to either a TENS (n=15) or a placebo (n=15) group. All participants completed 3 experimental sessions in a counterbalanced order separated by 2 days: (1) hypertonic saline infusion (5% NaCl); (2) isotonic saline infusion (0.9% NaCl); and (3) control. Each group received sensory electrical stimulation or placebo treatment for 20 minutes, respectively.Main Outcome Measures
Perceived pain was collected every 2 minutes using a 10-cm visual analog scale (VAS) for 50 minutes and analyzed using a mixed model analysis of covariance with repeated measures. Gait analyses were performed at baseline, infusion, and treatment. Sagittal and frontal knee angles and internal net joint torque across the entire stance were analyzed using a functional data analysis approach.Results
Hypertonic saline infusion increased perceived pain (4/10cm on a VAS; P<.05) and altered right knee angle (more flexion and less abduction; P<.05) and internal net joint torque (less extension and greater abduction; P<.05) across various stance phases. TENS treatment reduced perceived pain and improved right sagittal gait abnormalities as compared with placebo treatment (P<.05).Conclusions
This pain model increases perceived pain and induces compensatory gait patterns in a way that indicates potential quadriceps weakness. However, TENS treatment effectively reduces perceived pain and restores pain-induced gait abnormalities in sagittal knee mechanics. 相似文献17.

Objective
To determine whether multifidi size, intramuscular fat, or both, are associated with self-reported and performance-based physical function in older adults with and without chronic low back pain (LBP).Design
Case-control study.Setting
Individuals participated in a standardized evaluation in a clinical laboratory and underwent magnetic resonance imaging (MRI) of the lumbar spine at a nearby facility.Participants
A volunteer sample of community-dwelling older adults (N=106), aged 60 to 85 years, with (n=57) and without (n=49) chronic LBP were included in this secondary data analysis.Intervention
Average right-left L5 multifidi relative (ie, total) cross-sectional area (CSA), muscle-fat infiltration index (MFI) (ie, a measure of intramuscular fat), and relative muscle CSA (rmCSA) (ie, total CSA minus intramuscular fat CSA) were determined from MRIs. Linear regression modeling was performed with physical function measures as the dependent variables. Age, sex, and body mass index were entered as covariates. The main effects of L5 multifidi MFI and rmCSA, as well as their interaction with group assignment, were compared as independent variables.Main Outcome Measures
Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning subscale, timed Up and Go, gait speed, and fast stair descent performance.Results
Interaction terms between L5 multifidi MFI and group assignment were found to be significant contributors to the variance explained in all physical function measures (P≤.012). Neither the main effect nor the interaction with group assignment for L5 multifidi rmCSA significantly contributed to the variance explained in any of the physical function measures (P>.012).Conclusions
Among older adults with chronic LBP of at least moderate intensity, L5 multifidi muscle composition, but not size, may help to explain physical function. 相似文献18.

Objective
To determine the association between the amplitude of vastus medialis (VM) Hoffmann reflex (H-reflex) and pain level, self-reported physical function, and chronicity of pain in women with patellofemoral pain (PFP).Design
Cross-sectional study.Setting
Laboratory of biomechanics and motor control.Participants
Women diagnosed with PFP (N=15) aged 18 to 35 years.Interventions
Not applicable.Main Outcome Measures
Data on worst pain level during the previous month, self-reported physical function, and symptom duration (chronicity) were collected from the participants. Maximum evoked responses were obtained by electrical stimulation applied to the femoral nerve and peak-to-peak amplitudes of normalized maximal H-reflexes (maximal Hoffmann reflex/maximal motor wave ratios) of the VM were calculated. A Pearson product-moment correlation matrix (r) was used to explore the relations between the amplitude of VM H-reflex and worst pain during the previous month, self-reported function, and chronicity of pain.Results
Strong negative correlations were found between the amplitude of VM H-reflex and worst pain in the previous month (r=?.71; P=.003) and chronicity (r=?.74; P=.001). A strong positive correlation was found between the amplitude of VM H-reflex and self-reported physical function (r=.62; P=.012).Conclusions
The strong and significant relations reported in this study suggest that women with PFP showing greater VM H-reflex excitability tend to have lower pain, better physical function, and more recent symptoms. Therefore, rehabilitation strategies designed to increase the excitability of the monosynaptic stretch reflex should be considered in the treatment of women with PFP if their effectiveness is demonstrated in future studies. 相似文献19.

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. 相似文献20.
