Objective

To describe the incidence of overuse musculoskeletal injuries in service members with combat-related lower limb amputation.

Design

Retrospective cohort study.

Setting

Military treatment facilities.

Participants

Service members with deployment-related lower limb injury (N=791): 496 with a major lower limb amputation and 295 with a mild lower limb injury.

Interventions

Not applicable.

Main Outcome Measures

The outcomes of interest were clinical diagnosis codes (International Classification of Diseases–9th Revision) associated with musculoskeletal overuse injuries of the lumbar spine, upper limb, and lower limb regions 1 year before and 1 year after injury.

Results

The overall incidence of developing at least 1 musculoskeletal overuse injury within the first year after lower limb amputation was between 59% and 68%. Service members with unilateral lower limb amputation were almost twice as likely to develop an overuse lower or upper limb injury than those with mild combat-related injury. Additionally, service members with bilateral lower limb amputation were more than twice as likely to develop a lumbar spine injury and 4 times more likely to develop an upper limb overuse injury within the first year after amputation than those with mild combat-related injury.

Conclusions

Incidence of secondary overuse musculoskeletal injury is elevated in service members with lower limb amputation and warrants focused research efforts toward developing preventive interventions.  相似文献

Background

A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known whether an accelerated return to sport increases the risk of early-onset knee osteoarthritis (KOA).

Objective

To determine whether an accelerated return to sport post-ACLR (ie, <10 months) is associated with increased odds of early KOA features on magnetic resonance imaging (MRI) 1 year after surgery and to evaluate the relationship between an accelerated return to sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower limb function (good or poor).

Design

Cross-sectional study.

Setting

Private radiology clinic and university laboratory.

Participants

A total of 111 participants (71 male; mean age 30 ± 8 years) 1-year post-ACLR.

Methods

Participants completed a self-report questionnaire regarding postoperative return-to-sport data (specific sport, postoperative month first returned), and isotropic 3-T MRI scans were obtained.

Outcome Measures

Early KOA features (bone marrow, cartilage and meniscal lesions, and osteophytes) assessed with the MRI OA Knee Score. Logistic regression analyses evaluated the odds of early KOA features with an accelerated return to sport (<10 months post-ACLR versus ≥10 months or no return to sport) in the total cohort and stratified by type of ACL injury and lower limb function.

Results

Forty-six (41%) participants returned to competitive sport <10 months post-ACLR. An early return to sport was associated with significantly increased odds of bone marrow lesions (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.3-6.0) but not cartilage (OR 1.2, 95% CI 0.5-2.6) or meniscal lesions (OR 0.8, 95% CI 0.4-1.8) or osteophytes (OR 0.6, 95% CI 0.3-1.4). In those with poor lower limb function, early return to sport exacerbated the odds of bone marrow lesions (OR 4.6, 95% CI 1.6-13.5), whereas stratified analyses for type of ACL injury did not reach statistical significance.

Conclusion

An accelerated return to sport, particularly in the presence of poor lower limb function, may be implicated in posttraumatic KOA development.

Background

A variety of tests have been proposed to measure the performance of neck flexor muscles, but head-to-head comparisons hardly have been documented.

Objective

To compare reliability indexes, construct validity, and ability to discriminate between individuals with and without neck pain of 4 muscle tests (deep neck flexors endurance test [DNFET]; 2 variations of the craniocervical flexion test [CCFT1 and CCFT2]; and dynamometry).

Design

Reliability and validity study.

Setting

General community.

Participants

A total of 66 participants, 33 with chronic idiopathic neck pain (mean ± standard deviation pain intensity: 3.2 ± 1.9) and 33 without neck pain, from the general population.

Methods/Main Outcome

Neck muscle functioning was assessed with the CCFT1, the CCFT2, the DNFET, and dynamometry on 2 separate sessions. Participants with neck pain also were assessed for pain intensity, disability, pain catastrophizing, and fear of movement.

Results

Relative reliability of all tests was at least moderate (intraclass correlation coefficient ≥ 0.62), whereas measurement error was high, particularly for the DNFET (95% minimum detectable change ≥ 23.00 seconds). All tests showed moderate correlation (r ≥ 0.3) with at least 2 pain-related measures and moderate-to-strong correlations with each other. Principal component analysis retained 2 factors explaining 68%-73% of the variance of the 4 muscle tests. Significant differences between groups were found for the DNFET and dynamometry (P < .05).

Conclusion

The reliability indexes suggest that the DNFET and the CCFT may be more appropriate for group comparisons than for individual comparisons. The 4 tests seem to have construct validity, but they also seem to measure slightly different constructs.

Background

As one of the most common work-related musculoskeletal disorders and postural deviations, forward head posture (FHP), is considered to lead to muscle imbalance.

Objectives

The aim of this study is to investigate the bilateral cross-sectional area (CSA) of the deep neck flexor muscles at rest and during five stages of the craniocervical flexion (CCF) test in individuals with FHP and the controls with normal head posture.

Methods

Eighteen students with FHP and 18 controls with normal head posture, all females aged 18–35 years, participated in this study. Participants were categorized into two groups based on their craniovertebral angle. The CSA of the deep neck flexors was measured using ultrasonography while participants lay supine on the table with a pressure biofeedback unit placed under their necks in order to let the examiner measure the CSA of the muscles during rest and five stages of the CCF test including 22, 24, 26, 28, and 30 mmHg of the pressure biofeedback unit.

Results

A significant effect of contraction level was observed in both groups, indicating significant increases of the CSA of the deep neck flexors during contraction (F = 64.37, P < 0.001). No significant difference was evident for the CSA of the deep neck flexors between the groups, although the increase in the CSA of the deep neck flexors was up to 28 mmHg in the normal head posture group compared to 26 mmHg in the FHP group.

Conclusions

The results of the present study showed no significant difference between the performance of the deep neck flexors during the CCF test in FHP and normal head posture individuals, which challenge the common belief of the deep neck flexors weakness in individuals sustaining FHP.  相似文献

Objective

To test the effect that indicators of mobility device quality have on participation outcomes in community-dwelling adults with spinal cord injury, traumatic brain injury, and stroke by using structural equation modeling.

Design

Survey, cross-sectional study, and model testing.

Setting

Clinical research space at 2 academic medical centers and 1 free-standing rehabilitation hospital.

Participants

Community-dwelling adults (N=250; mean age, 48±14.3y) with spinal cord injury, traumatic brain injury, and stroke.

Interventions

Not applicable.

Main Outcomes Measures

The Mobility Device Impact Scale, Patient-Reported Outcomes Measurement Information System Social Function (version 2.0) scale, including Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities, and the 2 Community Participation Indicators' enfranchisement scales. Details about device quality (reparability, reliability, ease of maintenance) and device type were also collected.

Results

Respondents used ambulation aids (30%), manual (34%), and power wheelchairs (30%). Indicators of device quality had a moderating effect on participation outcomes, with 3 device quality variables (repairability, ease of maintenance, device reliability) accounting for 20% of the variance in participation. Wheelchair users reported lower participation enfranchisement than did ambulation aid users.

Conclusions

Mobility device quality plays an important role in participation outcomes. It is critical that people have access to mobility devices and that these devices be reliable.  相似文献

Objectives

To evaluate (1) the trajectory of resilience during the first year after a moderate-severe traumatic brain injury (TBI); (2) factors associated with resilience at 3, 6, and 12 months postinjury; and (3) changing relationships over time between resilience and other factors.

Design

Longitudinal analysis of an observational cohort.

Setting

Five inpatient rehabilitation centers.

Participants

Patients with TBI (N=195) enrolled in the resilience module of the TBI Model Systems study with data collected at 3-, 6-, and 12-month follow-up.

Interventions

Not applicable.

Main Outcome Measure

Connor-Davidson Resilience Scale.

Results

Initially, resilience levels appeared to be stable during the first year postinjury. Individual growth curve models were used to examine resilience over time in relation to demographic, psychosocial, and injury characteristics. After adjusting for these characteristics, resilience actually declined over time. Higher levels of resilience were related to nonminority status, absence of preinjury substance abuse, lower anxiety and disability level, and greater life satisfaction.

Conclusions

Resilience is a construct that is relevant to understanding brain injury outcomes and has potential value in planning clinical interventions.  相似文献

Objective

To assess how different decision-guiding factors, such as health- and performance-related stakeholders, as well as evidence-based guidelines, support the process-oriented final positive return-to-play (RTP) decision of head coaches responsible for semiprofessional sport teams.

Design

Cross-sectional survey.

Setting

Team sport.

Participants

A survey consisting of questions on the importance of different decision-guiding factors used when making the RTP decision after injuries was administered to and completed by head coaches (N=238) of semiprofessional players' teams.

Interventions

Not applicable.

Main Outcome Measures

With respect to helpfulness in the RTP decision-making process, the coaches rated both the importance of the opinions of physicians, physiotherapists, strength and conditioning coaches, and the athletes themselves, and the importance of the general and injury-specific RTP guidelines.

Results

Our survey revealed that the head coaches rely on physicians and physiotherapists to a large extent, to the athletes and to themselves to a medium extent, and to strength and conditioning coaches and RTP guidelines to a small but still relevant extent. The coaches' efforts to seek a shared decision-making process in RTP are, hence, partially evident.

Conclusions

A multitude of actuators intervene when making the RTP decision. The professionalization of the RTP process in semiprofessional sports includes the athletes themselves, the head coaches, the (external) physicians, the (external) physiotherapists, and the strength and conditioning coaches based on general RTP decision-making models and specific criteria related to injury type, sports type, level, and playing position. The development of awareness and implementation strategies of RTP models should be subject to further research.  相似文献

Objectives

To describe the prevalence of cannabis use in an adult sample with spinal cord injury (SCI) or traumatic brain injury (TBI) in Colorado, and to describe the self-reported reasons and side effects of cannabis use in this sample.

Design

Mixed-methods observational study, using focus group data and telephone survey.

Setting

Community.

Participants

Colorado adults who sustained SCI or moderate to severe TBI and received services through Craig Hospital.

Interventions

None.

Main Outcome Measures

Survey.

Results

Focus group participants identified issues that were then included in the survey development. Seventy percent of the 116 participants surveyed reported cannabis use before their injury (67% SCI, 74% TBI) and 48% reported use after their injury (53% SCI, 45% TBI). Overall, the most common reason for use was recreational (67%), followed by reducing stress/anxiety (62.5%) and improving sleep (59%). Among the respondents with SCI, the most common reasons for use were to reduce spasticity (70%), recreation (63%), and to improve sleep (63%). Among those with TBI, reasons endorsed were recreational (72%), reducing stress/anxiety (62%), and improving sleep (55%). Smoking was the most common method of use.

Conclusions

A majority of this sample reported using cannabis before injury, and approximately half reported using cannabis after injury. Both groups reported recreational use, whereas the group with SCI also highly endorsed using cannabis to address chronic medical conditions. Clinicians should be aware of the high prevalence of cannabis use in these populations and the impact such use may have on the individual’s medical management. Further research in this area is needed.  相似文献

Objective

To compare baseline kinesiophobia levels and their association with health-related quality of life across injury locations.

Design

Retrospective cross-sectional study.

Setting

Single, large outpatient physical therapy clinic within an academic medical center.

Participants

Patients (N=1233) who underwent an initial evaluation for a diagnosis related to musculoskeletal pain and completed the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11) and the Medical Outcomes Study 8-Item Short-Form Health Survey (SF-8) questionnaires within 7 days of their first visit were eligible for inclusion. Three hundred eighty patients were excluded because of missing data or because they were younger than 18 years. A total of 853 patients (mean age, 43.55y; range, 18–94y) were included.

Interventions

Not applicable.

Main Outcome Measures

Comparison of baseline kinesiophobia levels and their association with health-related quality of life across injury locations in an outpatient physical therapy setting.

Results

Separate analysis of variance models compared TSK-11 scores based on involved body region, and Pearson correlation coefficients were used to examine the association between TSK-11 scores and the SF-8 subscales at each body region. TSK-11 scores did not differ by body region (range, 23.9–26.1). Weak to moderate negative correlations existed between kinesiophobia and the SF-8 subscales.

Conclusions

Kinesiophobia levels appear elevated and negatively associated with health-related quality of life at initial physical therapy evaluation regardless of injury location. These findings suggest that physical therapists in outpatient orthopedic settings should implement routine kinesiophobia assessment and provide stratified care based on kinesiophobia levels across musculoskeletal conditions.  相似文献

Background

Serious isolated laryngeal injuries are uncommon in children.

Case Report

We describe the case of an 8-year-old boy with laryngeal injury and pneumomediastinum due to minor blunt neck trauma. He presented to the emergency department complaining of odynophagia and hoarseness, but without respiratory distress. Emphysema was seen between the trachea and vertebral body on initial cervical spine x-ray study, and flexible laryngoscopy revealed erythema and mild edema of both the right vocal cord and the arytenoid region. He recovered with conservative management only.

Why Should an Emergency Physician Be Aware of This?

We conclude that it is important to recognize subtle evidence of laryngeal injury secondary to blunt neck trauma to ensure early diagnosis. Initial cervical spine x-ray assessment should exclude both cervical spine fracture and local emphysema after blunt neck trauma. If patients with blunt neck trauma have evidence of a pneumomediastinum, the clinician should consider the possibility of aerodigestive injury.  相似文献

Background

Mortality prediction in patients with brain trauma during initial management in the emergency department (ED) is essential for creating the foundation for a better prognosis.

Objective

This study aimed to create a simple and useful survival predictive model for patients with isolated blunt traumatic brain injury that is easily available in the ED.

Methods

This is a retrospective study based on the trauma registry data of an academic teaching hospital. The inclusion criteria were age ≥ 15 years, blunt and not penetrating mechanism of injury, and Abbreviated Injury Scale (AIS) scores between 1 and 6 for head and 0 for all other body parts. The primary outcome was 30-day survival probability. Internal and external validation was performed.

Results

After univariate logistic regression analysis based on the derivation cohort, the final Predictor of Isolated Trauma in Head (PITH) model for survival prediction of isolated traumatic brain injury included Glasgow Coma Scale (GCS), age, and coded AIS of the head. In the validation cohort, the area under the curve of the PITH score was 0.970 (p < 0.0001; 95% confidence interval 0.960–0.978). Sensitivity and specificity were 95% and 81.7% at the cutoff value of 0.9 (probability of survival 90%), respectively.

Conclusions

The PITH model performed better than the GCS; Revised Trauma Score; and mechanism of injury, GCS, age, and arterial pressure. It will be a useful triage method for isolated traumatic brain injury in the early phase of management.  相似文献

Objective

To investigate the relation between posttraumatic stress (PTS) symptom severity and health-related quality of life (HRQoL) after severe traumatic brain injury (TBI).

Design

Longitudinal prospective multicenter, cohort study on severe TBI in Switzerland (2007–2011).

Setting

Hospital, rehabilitation unit, and/or patient’s living facility.

Participants

Patients with severe TBI (N=109) were included in the analyses. Injury severity was determined using the Abbreviated Injury Score of the head region after clinical assessment and initial computed tomography scan.

Interventions

Not applicable.

Main Outcome Measures

HRQoL (Medical Outcomes Study 12-Item Short-Form Health Survey Physical and Mental Component Summaries) and self-reported emotional, cognitive, and interpersonal functioning (Patient Competency Rating Scale for Neurorehabilitation).

Results

Multilevel models for patients >50 and ≤50 years of age revealed significant negative associations between PTS symptom severity and interpersonal functioning (P<.001 and P=.002), respectively. Among patients ≤50 years of age, PTS symptom severity was significantly associated with total functioning (P=.001) and emotional functioning (P<.001). Among all patients, PTS symptom severity was significantly associated with cognitive functioning (P<.001) and mental HRQoL (P=.01).

Conclusions

Findings indicate that PTS symptoms after severe TBI are negatively associated with HRQoL and emotional, cognitive, and interpersonal functioning.  相似文献

Background

Treatment of movement faults in the neck is known as an important factor in treatment of chronic neck pain. Along with the identification of site and direction of the faults, direction-movement control intervention retrains the control of the movement faults.

Purpose

This study was designed to investigate long-term effects of a direction-movement control training on pain, disability, head repositioning accuracy, function, cervical flexor endurance, and range of motion in female patients with chronic nonspecific neck pain.

Material and methods

Thirty women (36.5 ± 5.7 years) with chronic nonspecific neck pain were randomly allocated into two groups, i.e., an experimental group (n = 15) and a control group (n = 15). The experimental group performed the direction-movement control training for 30 min/day, three days per week for six months.All subjects were evaluated using the visual analog scale (VAS), range of motion (TOM), progressive iso-inertial lifting evaluation (PILE), neck disability Index (NDI), helmet attached with laser pointer using for head repositioning accuracy (HRA), and Trott's test (deep neck flexor endurance), in pre- and six-months post-treatment intervention.

Results

Significant differences were observed for the pain, neck disability Index, function endurance, head repositioning accuracy, range of motion, and cervical flexor endurance in the experimental group compared to that of control group.

Conclusion

Direction-movement control training is likely to be an effective training program to enhance body functionality through improvement of pain, function, endurance, head repositioning accuracy, range of motion, and cervical flexor endurance. Due to the high reported effect size for direction-movement control exercises, the application of the training is suggested as a supplementary method to improve chronic nonspecific neck pain in females.  相似文献

Background

Lower rib fractures are considered as a marker of intra-abdominal organ injury. Abdominal computed tomography (CT) is the “gold standard” examination for patients with lower rib fractures. However, the reported incidence of concomitant intra-abdominal injuries (IAI) is 20%–40%.

Objective

The purpose of this study was to evaluate the incidence of intra-abdominal organ injuries in blunt trauma patients with lower rib fractures.

Methods

Medical charts and radiology reports of patients with lower rib (from the 8th to 12th rib) fractures admitted to our center during a 6-year period were retrospectively reviewed. Patients were divided into two groups. Group I included patients with intra-abdominal injury (IAI) diagnosed either by CT or on urgent laparotomy, and Group II included those with normal abdominal CT scans. Data included demographics, mechanism of injury, laboratory tests, radiology results including number and location of fractured ribs, and incidence of IAI.

Results

Overall 318 patients were included in the study. Fifty-seven patients (17.9%) had 71 IAIs compared with 265 (82.1%) patients with no IAI. Logistic regression identified age younger than 55 years (relative risk [RR] = 7.2; 95% confidence interval [CI] 3.1–16.8; p = 0.001), bilateral rib fractures (RR = 3.9; 95% CI 1.1–13.5; p = 0.03) and decreased levels of hematocrit (RR = 2.4; 95% CI 1.2–4.8; p = 0.016) as independent risk factors for the presence of IAI.

Conclusions

Abdominal CT should be considered in blunt trauma patients with lower rib fractures who are younger than 55 years of age and have bilateral rib fractures and decreased levels of hematocrit on admission.  相似文献

Objective

To explore the factor structure of the UK Functional Independence Measure and Functional Assessment Measure (FIM+FAM) among focal and diffuse acquired brain injury patients.

Design

Criterion standard.

Setting

A National Health Service acute acquired brain injury inpatient rehabilitation hospital.

Participants

Referred sample of adults (N=447) admitted for inpatient treatment following an acquired brain injury significant enough to justify intensive inpatient neurorehabilitation

Intervention

Not applicable.

Outcome Measure

Functional Independence Measure and Functional Assessment Measure.

Results

Exploratory factor analysis suggested a 2-factor structure to FIM+FAM scores, among both focal-proximate and diffuse-proximate acquired brain injury aetiologies. Confirmatory factor analysis suggested a 3-factor bifactor structure presented the best fit of the FIM+FAM score data across both aetiologies. However, across both analyses, a convergence was found towards a general factor, demonstrated by high correlations between factors in the exploratory factor analysis, and by a general factor explaining the majority of the variance in scores on confirmatory factor analysis.

Conclusions

Our findings suggested that although factors describing specific functional domains can be derived from FIM+FAM item scores, there is a convergence towards a single factor describing overall functioning. This single factor informs the specific group factors (eg, motor, psychosocial, and communication function) after brain injury. Further research into the comparative value of the general and group factors as evaluative/prognostic measures is indicated.  相似文献

Background

Thoracic injuries are a major cause of death associated with blunt trauma in children. Screening for injury with chest x-ray study, compared with chest computed tomography (CT) scan, has been controversial, weighing the benefits of specificity with the detriment of radiation exposure.

Objective

To identify predictors of thoracic injury in children presenting as trauma activations to a Level I trauma center after blunt torso trauma, and to compare these predictors with those previously reported in the literature.

Methods

We performed a retrospective chart review of pediatric patients (<18 years of age) who presented to the Emergency Department of a Level I trauma center between June 2010 and June 2013 as a trauma activation after sustaining a blunt torso trauma and who received diagnostic imaging of the chest as part of their initial evaluation.

Results

Data analysis was performed on 166 patients. There were 33 patients (20%) with 45 abnormalities detected on diagnostic imaging of the chest, with the most common abnormalities being lung contusion (36%), pneumothorax (22%), and rib fracture (13%). Statistically significant predictors of abnormal diagnostic imaging of the chest included Glasgow Coma Scale score (GCS) < 15 (27% with abnormality vs. 13% without abnormality), hypoxia (22% vs. 5%), syncope/loss of consciousness (55% vs. 35%), cervical spine tenderness (12% vs. 3%), thoraco-lumbar-sacral spine tenderness (41% vs. 17%), and abdominal/pelvic tenderness (12% vs. 3%).

Conclusions

Based on our data, predictors of thoracic injury in children after blunt torso trauma include GCS < 15, hypoxia, syncope/dizziness, cervical spine tenderness, thoraco-lumbar-sacral spine tenderness, and abdominal/pelvic tenderness.  相似文献

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.

Background

In most developing countries, accessibility for people using walking aids is limited due to architectural and environmental barriers. As observed from anecdotal accounts, even a minor orthopaedic injury/disorder may restrict a person's ambulation due to fatigue associated with using walking aids. Hence this study was undertaken with the following objective.

Objective

to estimate the magnitude of energy consumption using energy expenditure index (EEI) during gait under different conditions.

Design

Repeated measures design (within subjects study).

Setting

School.

Participants

Ten healthy, typical young adults between 17 and 25 years of age.

Outcome measure

Energy Expenditure Index (EEI) was estimated for each of the conditions of the study using consistent measurement procedures.

Results

Energy consumption with immobilization is greater (ankle-16.2%, knee-36.7% and ankle and knee-49.2%) than typical self-selected ambulation. During on ground ambulation the energy cost was greatest for an axillary crutches than a standard walker with ankle and knee immobilized being the highest in relation to typical ambulation (78.2% greater). Axillary crutches were more efficient than a walker during stair climbing.

Conclusion

For young adults a standard walker may be the right option for over-ground ambulation, when a lower limb joint in immobilized; with an axillary crutch used during stair climbing.  相似文献
