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 compare sitting posture and movement strategies between chronic hemiparetic and healthy subjects while performing a drinking task, using statistical parametric mapping (SPM) and feature analysis.

Design

Cross-sectional study.

Setting

A university physical therapy department.

Participants

Participants (N=26) consisted of chronic hemiparetic (n=13) and healthy individuals (n=13) matched for sex and age.

Interventions

Not applicable.

Main Outcome Measures

The drinking task was divided into phases: reaching, transporting the glass to mouth, transporting the glass to table, and returning to initial position. An SPM 2-sample t test was used to compare the entire kinematic waveforms of different joint angles (trunk, scapulothoracic, humerothoracic, elbow). Joint angles at the beginning and end of the motion, movement time, peak velocity timing, trajectory deviation, normalized integrated jerk, and range of motion were extracted from the motion data. Group differences for these parameters were analyzed using independent t tests.

Results

At the static posture and beginning of the reaching phase, patients showed a shoulder position more deviated from the midline and externally rotated with increased scapula protraction, medial rotation, anterior tilting, trunk anterior flexion and inclination to the paretic side. Altered spatiotemporal variables throughout the task were found in all phases, except for the returning phase. Patients returned to a similar posture as the task onset, except for the scapula, which was normalized after the reaching phase.

Conclusions

Chronic hemiparetic subjects showed more deviations in the proximal joints during seated posture and reaching. However, the scapular movement drew nearer to the healthy individuals' patterns after the first phase, showing an interesting point to consider in rehabilitation programs.  相似文献

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.

Objective

To examine the task prioritization effects on postural-suprapostural dual-task performance in patients with early-stage Parkinson disease (PD) without clinically observed postural symptoms.

Design

Cross-sectional study. Participants performed a force-matching task while standing on a mobile platform, and were instructed to focus their attention on either the postural task (posture-first strategy) or the force-matching task (posture-second strategy).

Setting

University research laboratory.

Participants

Individuals (N=16) with early-stage PD who had no clinically observed postural symptoms.

Interventions

Not applicable.

Main Outcome Measures

Dual-task change (DTC; percent change between single-task and dual-task performance) of posture error, posture approximate entropy (ApEn), force error, and reaction time (RT). Positive DTC values indicate higher postural error, posture ApEn, force error, and force RT during dual-task conditions compared with single-task conditions.

Results

Compared with the posture-first strategy, the posture-second strategy was associated with smaller DTC of posture error and force error, and greater DTC of posture ApEn. In contrast, greater DTC of force RT was observed under the posture-second strategy.

Conclusions

Contrary to typical recommendations, our results suggest that the posture-second strategy may be an effective dual-task strategy in patients with early-stage PD who have no clinically observed postural symptoms in order to reduce the negative effect of dual tasking on performance and facilitate postural automaticity.  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

Objective

To explore the feasibility of a newly developed smartphone-based exercise program with an embedded self-classification algorithm for office workers with neck pain, by examining its effect on the pain intensity, functional disability, quality of life, fear avoidance, and cervical range of motion (ROM).

Design

Single-group, repeated-measures design.

Setting

The laboratory and participants' home and work environments.

Participants

Offices workers with neck pain (N=23; mean age ± SD, 28.13±2.97y; 13 men).

Intervention

Participants were classified as having 1 of 4 types of neck pain through a self-classification algorithm implemented as a smartphone application, and conducted corresponding exercise programs for 10 to 12min/d, 3d/wk, for 8 weeks.

Main Outcome Measures

The visual analog scale (VAS), Neck Disability Index (NDI), Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), Fear-Avoidance Beliefs Questionnaire (FABQ), and cervical ROM were measured at baseline and postintervention.

Results

The VAS (P<.001) and NDI score (P<.001) indicated significant improvements in pain intensity and functional disability. Quality of life showed significant improvements in the physical functioning (P=.007), bodily pain (P=.018), general health (P=.022), vitality (P=.046), and physical component scores (P=.002) of the SF-36. The FABQ, cervical ROM, and mental component score of the SF-36 showed no significant improvements.

Conclusions

The smartphone-based exercise program with an embedded self-classification algorithm improves the pain intensity and perceived physical health of office workers with neck pain, although not enough to affect their mental and emotional states.  相似文献

Objective

To assess the effectiveness of the Pilates method on pain, function, quality of life, and consumption of pain medication in patients with mechanical neck pain.

Design

The design was a randomized controlled trial, with a blinded assessor and intention-to-treat analysis.

Setting

The study took place in the outpatient clinic of the rheumatology department, referral center.

Participants

Patients (N=64) with chronic mechanical neck pain were randomly allocated to 2 groups: the Pilates group (PG) and a control group (CG).

Interventions

The PG attended 2 sessions of Pilates per week, for 12 weeks. The protocol included Pilates exercises performed on a mat and on equipment and was adapted depending on the physical fitness of each participant; the repetitions varied from 6 to 12, respecting patient reports of fatigue and pain, using a single series for each exercise. The CG received only the standard pharmacological treatment. Both groups were instructed to use acetaminophen 750 mg if necessary. Patients were evaluated at baseline after 45, 90, and 180 days.

Main Outcome Measures

We used the Numerical Pain Scale for pain, the Neck Disability Index for function, and the SF-36 questionnaire for quality of life.

Results

The groups were homogeneous at baseline, the only exception being body mass index (BMI), with the PG showing higher BMI. Regarding the assessment between groups over time, statistical differences were identified for pain (P<.001), function (P<.001) and the SF-36 (functional capacity, P=.019; pain, P<.001; general health, P=.022; vitality, P<.001; mental health, P=.012) with the PG consistently achieving better results. Drug consumption was lower in PG patients (P=.037).

Conclusions

This trial demonstrated the effectiveness of the Pilates method for the treatment of chronic mechanical neck pain, resulting in improvement of pain, function, quality of life, and reduction of the use of analgesics.  相似文献

Objective

To examine the occurrence of adverse events in patients undergoing assessment for pulmonary rehabilitation when a 6-minute walk test (6MWT) continues despite desaturation below 80%.

Design

Retrospective audit following REporting of studies Conducted using Observational Routinely-collected health Data (RECORD) Statement.

Setting

Large teaching hospital.

Participants

All patients (N=549) (55% men, mean age 69±11y) assessed for pulmonary rehabilitation (September 2005 to January 2016).

Interventions

The standardized tests were conducted by experienced cardiorespiratory physiotherapists. Oxyhemoglobin saturation was monitored continuously using a pulse oximeter (lowest value used for analysis). Medical records were reviewed, and adverse events defined as tachycardia, bradycardia, chest pain, or other sign/symptom necessitating cessation.

Main Outcome Measure

6MWT.

Results

Data from 672 walk tests were included with mean distance 369 (124) meters. The main diagnoses were chronic obstructive pulmonary disease (70%), interstitial lung disease (14%), and bronchiectasis (8%). Sixty individuals (11%) recorded desaturation below 80% without adverse events. Two adverse events were recorded during tests without desaturation; in 1 instance, chest pain with no evidence of cardiorespiratory compromise and in another, the patient stopped due to concern regarding blood sugar levels (11.5 mmol/L when tested). Independent predictors of desaturation to less than 80% were resting oxyhemoglobin saturation <95% (odds ratio [OR] 3.82, 95% confidence interval [CI] 2.06-7.08) and a diagnosis of interstitial lung disease or pulmonary arterial hypertension (OR 5.24, 95% CI 2.59-10.58).

Conclusions

This study found that desaturation to less than 80% during a 6MWT was not associated with adverse events in a large cohort of patients referred to pulmonary rehabilitation and assessed by experienced physiotherapists, suggesting that test cessation due to desaturation in stable patients may be unwarranted.  相似文献

Background

Deep neck flexor (DNF) muscles stabilize the neck and contribute to head acceleration control. The function of DNF in cervical spine dynamic stabilization has not been examined in athletes of any age group, including adolescents. This investigation was necessary prior to studying the DNF muscles’ role in cervical spine injury patterns.

Objectives

The objectives of this study were (1) to determine average Deep Neck Flexor Endurance Test (DNFET) time scores in high school?aged and university-aged subjects (aged 14-22 years); and (2) to establish the relationship between gender and age for adolescent DNFET time scores.

Design

Cross-sectional design.

Setting

Public high school and private university.

Participants

A total of 81 (40 male, 41 female) healthy high school and collegiate athletes.

Intervention

DNFET time scores (in seconds) were collected and means values were calculated. Interrater reliability was established using the first 15 university-aged subjects enrolled in the study.

Main Outcomes

Mean DNFET time (seconds) scores.

Results

The DNF muscle endurance interrater reliability coefficient of reproducibility for 4 allied health clinicians was intraclass correlation coefficient (2,4) 0.712 (confidence interval, 0.24-0.85). The mean (± standard deviation) DNFET time score for females was 31.86 (±8.53) seconds versus 35.57 (±10.43) seconds for males. The DNFET performance demonstrated a significant but fair correlation with age (r = 0.401, P = .0001). No significant performance differences were found between male and female subjects in the 14- to 17-year-old group (U = 187.0, P = .285), the 18- to 22-year-old group (U = 145.0, P = .215), or the total male versus female subject groups (U = 653.0, P = .083).

Conclusion

Our study establishes a normative data set available for the DNFET in the adolescent population. The fair correlation between DNFET time scores and age is consistent with other studies. These findings serve as a basis for clinician testing, objectifying, and monitoring DNF dysfunction in an adolescent athletic population.

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.

Background

The presence of subtle losses in hand dexterity after stroke affects the regaining of independence with regard to activities of daily living. Therefore, awareness of ipsilesional upper extremity (UE) function may be of importance when developing a comprehensive rehabilitation program. However, current hand function tests seem to be unable to identify asymptomatic UE impairments.

Objectives

To assess the motor coordination as well as the sensory perception of an ipsilesional UE using biomechanical analysis of performance-oriented tasks and conducting a Manual Tactile Test (MTT).

Design

Case-controlled study.

Setting

A university hospital.

Participants

A total of 21 patients with unilateral stroke, along with 21 matched healthy control subjects, were recruited.

Methods

Each participant was requested to perform a pinch?holding-up activity (PHUA) test, object-transport task, and reach-to-grasp task via motion capture, as well as the MTT.

Main Outcome Measurements

The kinetic data of the PHUA test, kinematics analysis of functional movements, and time requirement of MTT were analyzed.

Results

Patients with ipsilesional UE had an inferior ability to scale and produce pinch force precisely when conducting the PHUA test compared to the healthy controls (P < .05). The movement time was statistically longer and peak velocity was significantly lower (P < .05) in the performance-oriented tasks for the ipsilesional UE patients. The longer time requirement in 3 MTT subtests showed that the ipsilesional UE patients experienced degradation in sensory perception (P < .001).

Conclusion

Comprehensive sensorimotor assessments based on functional perspectives are valid tools to determine deficits in the sensation-perception-motor system in the ipsilesional UE. Integration of sensorimotor training programs for ipsilesional UE in future neuro-rehabilitation strategies may provide more beneficial effects to regain patients’ motor recovery and to promote daily living activity independence than focusing on paretic arm motor training alone.

Background

Spasticity is a common sequela of upper motor neuron pathology, such as cerebrovascular diseases and cerebral palsy. Intervention for spasticity of the ankle plantarflexors in physical therapy may include tone-inhibiting casting and/or orthoses for the ankle and foot. However, the physiological mechanism of tone reduction by such orthoses remains unclarified.

Objective

To investigate the electrophysiologic effects of tone-inhibiting insoles in stroke subjects with hemiparesis by measuring changes in reciprocal Ia inhibition (RI) in the ankle plantarflexor.

Design

An interventional before–after study.

Setting

Acute stroke unit or ambulatory rehabilitation clinic of a university hospital in Japan.

Participants

Ten subjects (47-84 years) with hemiparesis and 10 healthy male control subjects (31-59 years) were recruited.

Methods

RI of the spastic soleus in response to the electrical stimulation of the deep peroneal nerve was evaluated by stimulus-locked averaging of rectified electromyography (EMG) of the soleus while subjects were standing.

Main Outcome Measurements

The magnitude of RI, defined as the ratio of the lowest to the baseline amplitude of the rectified EMG at approximately 40 milliseconds after stimulation, was measured while subjects were standing with and without the tone-inhibiting insole on the hemiparesis side.

Results

Enhancement of EMG reduction with the tone-inhibiting insole was significant (P < .05) in the subjects with hemiparesis, whereas no significant changes were found in controls.

Conclusion

Tone-inhibiting insoles enhanced RI of the soleus in subjects after stroke, which might enhance standing stability by reducing unfavorable ankle plantarflexion tone.

Objective

To examine self-regulation strategies as correlates of physical activity in persons with multiple sclerosis (MS).

Design

Cross-sectional, or survey, study.

Setting

University-based research laboratory.

Participants

Convenience sample of persons with MS (N=68).

Interventions

Not applicable.

Main Outcome Measures

Exercise Self-Efficacy Scale (EXSE), 12-item Physical Activity Self-Regulation Scale (PASR-12), and Godin Leisure-Time Exercise Questionnaire (GLTEQ).

Results

Correlation analyses indicated that GLTEQ scores were positively and significantly associated with overall self-regulation (r=.43), self-monitoring (r=.45), goal-setting (r=.27), reinforcement (r=.30), time management (r=.41), and relapse prevention (r=.53) PASR-12 scores. Regression analyses indicated that relapse prevention (B=5.01; SE B=1.74; β=.51) and self-monitoring (B=3.65; SE B=1.71; β=.33) were unique predictors of physical activity behavior, and relapse prevention demonstrated a significant association with physical activity behavior that was accounted for by EXSE.

Conclusions

Our results indicate that self-regulatory strategies, particularly relapse prevention, may be important correlates of physical activity behavior that can inform the design of future behavioral interventions in MS.  相似文献

Background

Cerebral palsy (CP) is a chronic condition that affects children and has an impact on social and physical activity, as well as participation in daily life. Participation and quality of life (QOL) are 2 important measures of successful rehabilitation that have not been well studied in children with CP.

Objective

To report levels of participation and examine the relationship of participation to QOL in ambulatory children with CP.

Design

Secondary analysis, cross-sectional cohort study.

Setting

Regional pediatric specialty care center.

Participants

A cohort of 128 ambulatory children with CP, Gross Motor Function Classification System levels I-III, age 2-9 years.

Interventions

Not applicable.

Main Outcome Measures

Pediatric Quality of Life Inventory; Assessment of Life Habits; and Children’s Assessment of Participation and Enjoyment and Assessment of Preschool Children’s Participation.

Results

Participation was negatively associated with increasing Gross Motor Function Classification System but not age. Level of participation was associated with psychosocial QOL (2.97, P = .001) and total QOL (54.70, P = .03) but not physical QOL. There was a positive relationship between physical activity performance (0.63, P = .001), walking performance (0.002, P = .01), and communication level (7.23, P = .05) with physical QOL. Increasing age and decreased frequency of participation were negatively associated with all QOL domains.

Conclusions

The results suggest that participation in daily life is negatively influenced by physical impairment and that levels of participation are positively associated with psychosocial and total QOL among ambulatory children with CP. This suggests that participation influences QOL and further studies are needed to determine the aspects of participation directly impacting QOL in ambulatory children with CP.

Objective

To evaluate whether current Dutch primary care clinicians offer tailored treatment to patients with low back pain (LBP) or neck pain (NP) according to their risk stratification, based on the Keele STarT (Subgroup Targeted Treatment) Back-Screening Tool (SBT).

Design

Prospective cohort study with 3-month follow-up.

Setting

Primary care.

Participants

General practitioners (GPs) and physiotherapists included patients (N=284) with nonspecific LBP, NP, or both.

Interventions

Patients completed a baseline questionnaire, including the Dutch SBT, for either LBP or NP. A follow-up measurement was conducted after 3 months to determine recovery (using Global Perceived Effect Scale), pain (using Numeric Pain Rating Scale), and function (using Roland Disability Questionnaire or Neck Disability Index). A questionnaire was sent to the GPs and physiotherapists to evaluate the provided treatment.

Main Outcome Measures

Prevalence of patients' risk profile and clinicians' applied care, and the percentage of patients with persisting disability at follow-up. A distinction was made between patients receiving the recommended treatment and those receiving the nonrecommended treatment.

Results

In total, 12 GPs and 33 physiotherapists included patients. After 3 months, we analyzed 184 patients with LBP and 100 patients with NP. In the LBP group, 52.2% of the patients were at low risk for persisting disability, 38.0% were at medium risk, and 9.8% were at high risk. Overall, 24.5% of the patients with LBP received a low-risk treatment approach, 73.5% a medium-risk, and 2.0% a high-risk treatment approach. The specific agreement between the risk profile and the received treatment for patients with LBP was poor for the low-risk and high-risk patients (21.1% and 10.0%, respectively), and fair for medium-risk patients (51.4%). In the NP group, 58.0% of the patients were at low risk for persisting disability, 37.0% were at medium risk, and 5.0% were at high risk. Only 6.1% of the patients with NP received the low-risk treatment approach. The medium-risk treatment approach was offered the most (90.8%), and the high-risk approach was applied in only 3.1% of the patients. The specific agreement between the risk profile and received treatment for patients with NP was poor for low-risk and medium-risk patients (6.3% and 48.0%, respectively); agreement for high-risk patients could not be calculated.

Conclusions

Current Dutch primary care for patients with nonspecific LBP, NP, or both does not correspond to the recommended stratified-care approach based on the SBT, as most patients receive medium-risk treatment. Most low-risk patients are overtreated, and most high-risk patients are undertreated. Although the stratified-care approach has not yet been validated in Dutch primary care, these results indicate there may be substantial room for improvement.  相似文献

Objectives

To investigate the impact that the presence of chronic low back pain with radiculopathy (CLBPR) may have on (1) energy efficiency and (2) energy capacity among community-dwelling older adults.

Design

Matched case-control study.

Setting

Clinical research laboratory.

Participants

Included in the analysis were community-dwelling older adults (N=38, 60-85 years) with and without CLBPR. Participants were matched between-groups on age (±5 years), sex, and diabetic status.

Interventions

Not applicable.

Main Outcome Measures

Energy cost of walking at self-selected speed (ie, energy efficiency) and peak volume of oxygen consumed (ie, energy capacity).

Results

Older adults with CLBPR had a higher energy cost of walking at self-selected speed (P=.009) and lower peak volume of oxygen consumed while walking (P=.050), compared to those without pain.

Conclusions

Older adults with CLBPR may benefit from specific rehabilitative interventions that target these potentially modifiable energetic outcomes, thereby reducing the risk of mobility decline. Future studies should identify which mechanisms specifically contribute to diminished energy efficiency and capacity among older adults with CLBPR.  相似文献

Results

The measure was completed by 89.4% of the sample with most participants completing the measure in <8 minutes. After controlling for age, sex, psychiatric history, drug or alcohol history, and history of developmental disability, worst TBI severity was significantly associated with scores on the RPQ, F(2,230)=4.56, P=.011, and having a TBI within the past 2 years was associated with higher scores on the cognitive factor subscale of the RPQ, F(1,75)=7.7, P=.007.

Conclusions

The online administration of the Ohio State University Traumatic Brain Injury Identification Method appears to be feasible in the general population. Preliminary validity was demonstrated for the indices of worst TBI severity and time since most recent TBI.  相似文献

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

Objective

To examine the validity of the self-report Work-Disability Functional Assessment Battery (WD-FAB) physical function scales relative to clinician ratings of function and a performance-based functional capacity evaluation called the Physical Work Performance Evaluation (PWPE).

Design

Cross-sectional.

Setting

Outpatient rehabilitation.

Participants

Adults (N=50) participating in physical therapy for musculoskeletal conditions.

Interventions

Not applicable.

Main Outcome Measures

Patients completed the PWPE and the WD-FAB physical function scales including Changing and Maintaining Body Position, Whole Body Mobility, Upper Body Function, and Upper Extremity Fine Motor. The physical therapist also answered the WD-FAB questions on the patient’s physical functioning. The WD-FAB computer-adaptive test version administered up to 10 items for each scale. The PWPE produces ratings from 0 to 5 indicating overall Level of Work ability: 0 (unable to work); 1 (sedentary); 2 (light); 3 (medium); 4 (heavy); 5 (very heavy). The PWPE also produces Level of Work ability ratings in the Dynamic Strength, Position Tolerance, and Mobility subsections.

Results

Participating in the study were 50 patients with 1 or more conditions (shoulder, n=21; knee, n=16; low back, n=13; ankle/foot, n=10; neck, n=8; hip, n=7). The patient-based WD-FAB scores demonstrated moderate, statistically significant correlations with the provider proxy WD-FAB report (R=.49-.65). The WD-FAB Upper Body Function scale scores demonstrated moderate strength relationships with the PWPE overall ratings. The Whole Body Mobility and Changing and Maintaining Body Position scales did not demonstrate statistically significant relationships with the PWPE overall ratings.

Conclusions

We found moderate evidence for validity for the WD-FAB Upper Body Function, Whole Body Mobility, and Changing and Maintaining Body Position scales relative to clinician report and varied evidence relative to the PWPE in this clinical sample.  相似文献
