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2.

Background
Preoperative progressive resistance training (PRT) is controversial in patients scheduled for total knee arthroplasty (TKA), because of the concern that it may exacerbate knee joint pain and effusion.Objective
To examine whether preoperative PRT initiated 5 weeks prior to TKA would exacerbate pain and knee effusion, and would allow a progressively increased training load throughout the training period that would subsequently increase muscle strength.Design
Secondary analyses from a randomized controlled trial (NCT01647243).Setting
University Hospital and a Regional Hospital.Patients
A total of 30 patients who were scheduled for TKA due to osteoarthritis and assigned as the intervention group.Methods
Patients underwent unilateral PRT (3 sessions per week). Exercise loading was 12 repetitions maximum (RM) with progression toward 8 RM. The training program consisted of 6 exercises performed unilaterally.Main outcome measures
Before and after each training session, knee joint pain was rated on an 11-point scale, effusion was assessed by measuring the knee joint circumference, and training load was recorded. The first and last training sessions were initiated by 1 RM testing of unilateral leg press, unilateral knee extension, and unilateral knee flexion.Results
The median pain change score from before to after each training session was 0 at all training sessions. The average increase in knee joint effusion across the 12 training sessions was a mean 0.16 cm ± 0.23 cm. No consistent increase in knee joint effusion after training sessions during the training period was found (P = .21). Training load generally increased, and maximal muscle strength improved as follows: unilateral leg press: 18% ± 30% (P = .03); unilateral knee extension: 81% ± 156% (P < .001); and unilateral knee flexion: 53% ± 57% (P < .001).Conclusion
PRT of the affected leg initiated shortly before TKA does not exacerbate knee joint pain and effusion, despite a substantial progression in loading and increased muscle strength. Concerns for side effects such as pain and effusion after PRT seem unfounded.Level of Evidence

Objective
To investigate the effect of a supervised upper limb (UL) program (SULP) compared to no supervised UL program (NULP) after lung transplantation (LTx).Design
Randomized controlled trial.Setting
Physiotherapy gym.Participants
Participants (N=80; mean age, 56±11y; 37 [46%] men) were recruited after LTx.Interventions
All participants underwent lower limb strength thrice weekly and endurance training. Participants randomized to SULP completed progressive UL strength training program using handheld weights and adjustable pulley equipment.Main Outcome Measures
Overall bodily pain was rated on the visual analog scale. Shoulder flexion and abduction muscle strength were measured on a hand held dynamometer. Health related quality of life was measured with Medical Outcomes Study 36-item Short Form health Survey and the Quick Dash. Measurements were made at baseline, 6 weeks, 12 weeks, and 6 months by blinded assessors.Results
After 6 weeks of training, participants in the SULP (n=41) had less overall bodily pain on the visual analog scale than did participants in the NULP (n=36) (mean VAS bodily pain score, 2.1±1.3cm vs 3.8±1.7cm; P<.001) as well as greater UL strength than did participants in the NULP (mean peak force, 8.4±4.0Nm vs 6.7±2.8Nm; P=.037). At 12 weeks, participants in the SULP better quality of life related to bodily pain (76±17 vs 66±26; P=.05), but at 6 months there were no differences between the groups in any outcome measures. No serious adverse events were reported.Conclusions
UL rehabilitation results in short-term improvements in pain and muscle strength after LTx, but no longer-term effects were evident. 相似文献4.

Background
Mobilisation with movement treatment techniques have been used to increase the range of motion following pathologies associated with shoulder, elbow and ankle joints. Lack of posterior tibial glide and reflex muscle inhibition are common physical impairments in individuals with post-traumatic stiffness of the knee joint. Current evidence is lacking for the benefits of mobilisation with movement treatment techniques for the knee joint disorders.Objective
The purpose of this study was to investigate the short-term effects of mobilisation with movement techniques following post-traumatic stiffness of the knee joint.Methods
Twenty consecutive patients with post-traumatic stiffness of the knee joint with a minimum available 80° knee flexion range of motion were included. One group pre-to-post-test study design was employed, in which the active knee flexion range of motion was used as an outcome measure. The mobilisation with movement treatment techniques was implemented with three sets of ten repetitions on each treatment occasion for a period of 3 days.Results
The mobilisation with movement treatment techniques significantly improved the active knee flexion range of motion (p = 0.000) from pre-treatment to post-treatment.Conclusions
The findings from this study demonstrated immediate benefits in outcomes following mobilisation with movement treatment techniques in a cohort of patients with post-traumatic stiffness of the knee joint. 相似文献5.
Background
Patients with acute anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries from sport-related activities are frequently seen in the emergency department (ED). However, knee instability tests are known to show variable sensitivity and specificity. These tests would also have limited functionality in patients with severe pain and swelling in the knee.Case Report
A 19-year-old female judo player presented to the ED with severe left knee pain. She had abruptly twisted her left knee while she was shoulder-throwing her opponent. She complained of severe pain and refused physical examination of the knee injury; as a result, evaluation of knee instability could not be performed. However, a point-of-care ultrasound helped in making a prompt and accurate diagnosis of simultaneous, complete rupture and partial ruptures of the ACL and PCL, respectively. The ultrasound findings correlated well with the magnetic resonance imaging images in the assessment of the combined ACL-PCL ruptures. The patient underwent simultaneous arthroscopic ACL and PCL reconstruction with a hamstring tendon autograft and was discharged.Why Should an Emergency Physician Be Aware of This?
Point-of-care ultrasound imaging of the knee in trauma patients may be helpful for diagnosis of ACL and PCL injuries by augmenting findings of physical examinations in patients with severe pain and swelling in the knee. Ultimately, it may lead to more accurate diagnosis and treatment plans in knee trauma patients. 相似文献6.
Background
Women are at greater risk for knee osteoarthritis and numerous other lower limb musculoskeletal disorders. Arch drop during pregnancy and the resultant excessive pronation of the feet may alter loading patterns and contribute to the greater prevalence of knee osteoarthritis in women.Objective
To determine the effect of arch drop on tibial rotation and tibiofemoral contact stress.Design
Interventional study with internal control.Setting
Biomechanics laboratory.Participants
Eleven postpartum women (age 33.4 ± 5.3 years, body mass 76.1 ± 13.5 kg) who had lost arch height with pregnancy in a previous study.Methods
Subjects underwent standing computed tomography (SCT) with their knees in a 20° fixed-flexed position with and without semirigid arch supports to reconstitute prepregnancy arch height. Magnetic resonance imaging of the knee was acquired at a flexion angle equivalent to that of SCT. Bone and cartilage were manually segmented on the magnetic resonance images and segmented surfaces were registered to the 3-dimensional SCT image sets for the arch-supported and -unsupported conditions. These models were used to measure changes in tibial rotation, as well as to estimate contact stress in the medial and lateral tibiofemoral compartments, using computational methods.Main Outcome Measures
Change in tibial rotation and tibiofemoral contact stress with arch drop.Results
Arch drop resulted in a mean tibial internal rotation of 0.75 ± 1.33° (P = .02). Changes in mean or peak contact stress were not detected.Conclusions
Arch drop causes internal tibial rotation, resulting in a shift in the tibiofemoral articulation. An associated increase in contact stress was not detected. Internal rotation of the tibia increases stress on the anterior cruciate ligament and menisci, potentially explaining the greater prevalence of knee disorders in postpartum women.Level of Evidence

Objectives
The role of a myofascial release (MFR) on flexion contractures after total knee arthroplasty (TKA) has not yet been elucidated. Therefore, the purpose of this study was to determine its immediate effect on such patients.Methods
In this A-B single subject experimental study, 33 TKA's patients with knee flexion contracture had their gluteal, posterior fascia lata, posterior crural and plantar fasciae released. Patients' knee range of motion (KROM), pain and muscle electric activity were assessed pre- and post-intervention.Results
An increase in electric activity of the biceps femoris muscle was identified after treatment (pre RMS = 0.087 ± 0.066 V; post RMS = 0.097 ± 0.085 V; p = 0.037). Mean gain of KROM was 5.72 ± 6.27, correspondent to an 11.9% improvement (p = 0.01). Eight subjects had their pain decreased on 56.9% (p = 0.04).Conclusions
MFR increased muscle activity, reduced pain and improved the KROM of TKA patients. Thus, MFR is a useful resource of rehabilitation after TKA. 相似文献8.

Background
Whole body vibration (WBV) has been widely used as a modality for physical activity. In fact, WBV has been used for physical rehabilitation, and to improve muscle performance; but there is little information about its effects on heart rate variability (HRV).Aim
The aim of this study was to evaluate the effect of vibration on HRV of the elderly using the vibratory platform.Methods
Eleven older adults (7 men, 4 women), aged between 60 and 75 years, were subjected to WBV. The study consisted of a single session of WBV with volunteers standing upright for 10 min on the oscillating platform, with frequency of vibration set at 20 Hz (displacement ± 6 mm; orbital vibration). Pre (baseline) and post-WBV electrocardiograph signals were acquired using a cardiac monitor; and data were statistically analyzed using paired Student's t-test or Wilcoxon test, as appropriate.Results
The results demonstrated an increase in SDNN (standard deviation (SD) beat-to-beat, N–N intervals), rMSSD (square root of the mean squared difference of successive N–Ns) and pNN50 (proportion of N–N50 divided by total number of N–Ns) post WBV (p = 0.032, p = 0.024 e p = 0.044, respectively), compared to baseline. The present study thus demonstrated that time domain variables (i.e., SDNN, rMSSD, and pNN50) increase post WBV.Conclusions
Older individuals are at high risk of developing cardiovascular diseases. As seen in the study, WBV improves HRV; and may help reduce risk of cardiac ailments. Moreover, WBV does not require extensive physical activity on the part of the participant. This makes WBV potentially beneficial to the elderly population. Further studies on WBV using different frequencies and training schedules may improve its applicability in clinics. 相似文献9.

Background
Swimming has no effect on bone mass or structure. Therefore, adolescent swimmers present similar bone strength values when compared to normo-active controls, and lower values when compared to weight-bearing athletes. It thus seems necessary to try to improve bone structure and strength of adolescent swimmers through a weight-bearing intervention in order to reduce the risk of suffering osteoporosis later in life.Objective
To evaluate the effects of a 6-month whole body vibration (WBV) intervention on bone strength and structure of adolescent swimmers.Design
Randomized controlled trial.Setting
Research center.Participants
A total of 51 swimmers (14.4 ± 2.0 years) participated in the study.Methods
Swimmers were randomly allocated into 2 groups: 20 swimmers (9 females) who only performed their swimming training, and 31 swimmers (15 females) who performed their swimming training and received a WBV intervention (3.6-11.6 g) 3 times per week during 6 months (VIB).Outcome measurements
Peripheral quantitative computed tomography was performed in the nondominant tibia of all swimmers at 4%, 38%, and 66% of the tibia length before and after the intervention.Results
No differences between groups in any bone structure variable were found at pre- or postintervention. Both groups presented similar improvements in time, and no group by time interactions were found, suggesting that the WBV intervention was not intense enough to achieve positive changes in bone strength or structure.Conclusion
WBV, at the chosen intensities and durations, had no effect on adolescent swimmers’ bone strength or structure. Future studies should test other weight-bearing interventions aiming to improve bone strength and structure of adolescent swimmers.Level of Evidence

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.Level of evidence

Objective
To investigate the relationship between spinal cord damage and specific motor function in participants with incomplete spinal cord injury (iSCI).Design
Single-blinded, cross-sectional study design.Setting
University setting research laboratory.Participants
Individuals with chronic cervical iSCI (N=14; 1 woman, 13 men; average age ± SD, 43±12y).Interventions
Not applicable.Main Outcome Measures
Axial T2-weighted magnetic resonance imaging (MRI) of spinal cord damage was performed in 14 participants with iSCI. Each participant's damage was processed for total damage quantification, lateral corticospinal tract (LCST) and gracile fasciculus (GF) analysis. Plantarflexion and knee extension were quantified using an isokinetic dynamometer. Walking ability was assessed using a 6-minute walk test.Results
Total damage was correlated with plantarflexion, knee extension, and distance walked in 6 minutes. Right LCST damage was correlated with right plantarflexion and right knee extension, while left LCST damage was correlated with left-sided measures. Right and left GF damage was not correlated with the motor output measures.Conclusions
MRI measures of spinal cord damage were correlated to motor function, and this measure appears to have spatial specificity to descending tracts, which may offer prognostic value after SCI. 相似文献12.

Background
Bone marrow aspirate concentrate (BMC) is one of the few cell-based therapies available as a possible biological treatment for early osteoarthritis (OA). Its efficacy, safety, and benefit compared with other treatments are still to be determined.Objective
To assess the clinical outcomes of patients undergoing intra-articular injection of BMC for the treatment of early knee and hip OA.Design
Prospective, cohort study.Setting
Single institution, quaternary level of care.Patients
Nineteen patients (16 female and 3 male), totaling 25 joints (10 knees, 15 hips), treated with intra-articular BMC for early OA between 2014 and 2016. The mean age at time of the procedure was 58 ± 12.7 years (range, 30-80 years). The mean follow-up was 13.2 ± 6.3 months (range, 6-24 months). Inclusion criteria included ≥18 years; knee OA, Kellgren–Lawrence grade I-II; hip OA, Tönnis grade I-II; first-time intra-articular BMC therapy, after unsuccessful symptomatic and conservative treatments (ie, physical therapy, analgesics and anti-inflammatory drugs) for 6 months. Exclusion criteria included pregnancy; malignancy; rheumatologic diseases; infection; Kellgren–Lawrence grade III-IV; Tönnis grade III; and previous intra-articular injections or surgery.Interventions
All patients had autologous bone marrow aspirate harvested from the iliac crest and centrifuged to achieve BMC, for intra-articular injection.Main Outcome Measurements
The hypothesis was formulated before the study. Patient-reported outcomes measures were assessed preoperatively and at last follow-up using the Western Ontario and McMaster Universities Arthritis Index.Results
Western Ontario and McMaster Universities Arthritis Index improved from a baseline of 40.8 ± 18.3% to 20.6 ± 17% (P < .001) at final follow-up. The satisfaction rate was 63.2%. The minimal clinically important difference threshold of 9.15 points was reached by 64% of the patients. Two patients were converted to total hip arthroplasty at 8 months after BMC injection.Conclusions
Intra-articular injections of BMC for the treatment of early knee or hip OA were safe and demonstrated satisfactory results in 63.2% of patients. Future studies are necessary to determine the efficacy of this technique and its safety profile.Level of Evidence

Background
Patients with Parkinson disease (PD) present cardiovascular autonomic dysfunction that impairs blood pressure control. However, cardiovascular responses during resistance exercise are unknown in these patients.Objective
To investigate cardiovascular responses during resistance exercise performed with different muscle masses in patients with PD.Design
Prospective, repeated-measures.Setting
Exercise Hemodynamic Laboratory, School of Physical Education and Sport, University of São Paulo.Participants
Thirteen patients with PD (4 women, 62.7 ± 1.3 years, stages 2-3 of the modified Hoehn and Yahr scale; “on” state of medication) and 13 paired control patients without PD (7 women, 66.2 ± 2.0 years).Interventions
Both groups performed, in a random order, bilateral and unilateral knee extension exercises (2 sets, 10-12 maximal repetition, 2-minute intervals).Main Outcome Measurements
Systolic blood pressure (SBP) and heart rate (HR) were assessed before (pre) and during the exercises.Results
Independent of set and exercise type, SBP and HR increases were significantly lower in PD than the control group (combined values: +45 ± 2 versus +73 ± 4 mm Hg and +18 ± 1 versus +31 ± 2 bpm, P = .003 and .007, respectively). Independently of group and set, the SBP increase was greater in the bilateral than the unilateral exercise (combined values: +63 ± 4 versus +54 ± 3 mm Hg, P = .002), whereas the HR increase was similar. In addition, independently of group and exercise type, the SBP increase was greater in the second than the first set (combined values: +56 ± 4 versus +61 ± 4 mm Hg, P = .04), whereas the HR increases were similar.Conclusions
Patients with PD present attenuated increases in SBP and HR during resistance exercise in comparison with healthy subjects. These results support that resistance exercise is safe and well tolerated for patients with PD from a cardiovascular point of view supporting its recommendation for this population.Level of Evidence

Background
Iliotibial band syndrome has been associated with altered hip and knee kinematics in runners. Previous studies have recommended further research on neuromuscular factors at the hip. The frontal plane hip muscles have been a strong focus in strength comparison but not for electromyography investigation.Objective
To compare hip surface electromyography, and frontal plane hip and knee kinematics, in runners with and without iliotibial band syndrome.Design
Observational cross-sectional study.Setting
Biomechanics research laboratory within a university.Participants
Thirty subjects were recruited consisting of 15 injured runners with iliotibial band syndrome and 15 gender-, age-, and body mass index–matched controls. In each group, 8 were male runners and 7 were female runners. Inclusion criteria for the injured group were pain within 2 months related to iliotibial band syndrome and a positive Noble compression test. Participants were excluded if they reported other lower extremity diagnoses within the last year or active lower extremity or low back pain not related to iliotibial band syndrome. Controls were excluded if they reported a history of iliotibial band syndrome. Convenience sampling was used based on referrals from local running clinics and orthopedic clinics.Methods
Three-dimensional motion capture was performed with 10 high-speed cameras synchronized with wireless surface electromyography during a 30-minute run. The first data point was at 3 minutes, using a constant speed of 2.74 meters per second. A second data point was at 30 minutes, using a self-selected pace by the participant to allow for a challenging run until completion at 30 minutes.Main Outcome Measurements
Motion capture was reported as peak kinematic values from heel strike to peak knee flexion for hip adduction and knee adduction. Surface electromyography was reported as a percentage of maximal voluntary contraction for the gluteus maximus, gluteus medius and tensor fascia latae muscles.Results
Injured runners demonstrated increased knee adduction compared with control runners at 30 minutes (P = .002, control = –1.48°, injured = 3.74°). Tensor fasciae latae muscle activation in injured runners was increased compared with control runners at 3 minutes (P = .017, control = 7% maximal voluntary isometric contraction, injured = 11% maximal voluntary isometric contraction).Conclusion
The results of this study suggest that lateral knee pain in runners localized to the distal iliotibial band is associated with increased knee adduction at 30 minutes. Increased tensor fasciae latae muscle activation at 3 minutes is noted, but more investigation is needed to better understand the clinical meaning. These findings are consistent with but not conclusive evidence supporting the theory that neuromuscular factors of the hip muscles may contribute to increased knee adduction in runners with iliotibial band syndrome. We advise caution using these findings to support treatments intended to modify tensor fasciae latae activation, given the small differences of 4% in muscle activation. Increased knee adduction in runners at 30 minutes was over 5° and beyond the minimal detectable difference. Additional research is needed to confirm whether the degree of knee adduction changes earlier versus later in a run and whether fatigue is a clinically relevant factor.Level of Evidence

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.Level of Evidence

Objective
To evaluate the effect of pulmonary rehabilitation (PR) on exercise performance and quality of life in patients with chronic obstructive pulmonary disease (COPD) with different degrees of static lung hyperinflation (LH).Design
Retrospective cohort study.Setting
PR network.Participants
A cohort of 1981 patients with COPD (55% men; age: 66.8±9.3y; forced expiratory volume in the first second%: 50.7±19.5; residual volume [RV]%: 163.0±49.7).Intervention
An interdisciplinary PR program for patients with COPD consisting of 40 sessions.Main Outcome Measures
Participants were stratified into 5 quintiles according to baseline RV and were evaluated on the basis of pre- and post-PR 6-minute walk distance (6MWD), constant work rate test (CWRT), and Saint George’s Respiratory Questionnaire (SGRQ), among other clinical parameters.Results
With increasing RV quintile, patients were younger, more frequently women, had lower forced expiratory volume in the first second%, lower body mass index and fat-free mass index, shorter 6MWD, shorter CWRT, and worse SGRQ scores (P<.01). All RV strata improved after PR in all 3 outcomes (P<.001). Nevertheless, higher, compared to lower RV categories, had lower ΔCWRT (P<.01) but similar Δ6MWD (P=.948) and ΔSGRQ (P=.086) after PR.Conclusions
LH in COPD is related to younger age, female sex, lower body weight, worse exercise capacity and health status, but did not prevent patients from benefitting from PR. LH, however, influences walking and cycling response after PR differently. 相似文献17.

Objective
To systematically characterize the effect of flexion synergy expression on the manifestation of elbow flexor stretch reflexes poststroke, and to relate these findings to elbow flexor stretch reflexes in individuals without neurologic injury.Design
Controlled cohort study.Setting
Academic medical center.Participants
Participants (N=20) included individuals with chronic hemiparetic stroke (n=10) and a convenience sample of individuals without neurologic or musculoskeletal injury (n=10).Interventions
Participants with stroke were interfaced with a robotic device that precisely manipulated flexion synergy expression (by regulating shoulder abduction loading) while delivering controlled elbow extension perturbations over a wide range of velocities. This device was also used to elicit elbow flexor stretch reflexes during volitional elbow flexor activation, both in the cohort of individuals with stroke and in a control cohort. In both cases, the amplitude of volitional elbow flexor preactivation was matched to that generated involuntarily during flexion synergy expression.Main Outcome Measures
The amplitude of short- and long-latency stretch reflexes in the biceps brachii, assessed by electromyography, and expressed as a function of background muscle activation and stretch velocity.Results
Increased shoulder abduction loading potentiated elbow flexor stretch reflexes via flexion synergy expression in the paretic arm. Compared with stretch reflexes in individuals without neurologic injury, paretic reflexes were larger at rest but were approximately equal to control muscles at matched levels of preactivation.Conclusions
Because flexion synergy expression modifies stretch reflexes in involved muscles, interventions that reduce flexion synergy expression may confer the added benefit of reducing spasticity during functional use of the arm. 相似文献18.
Background
Low back pain (LBP) is commonly associated with paraspinal muscle dysfunctions. A method to study deep lumbar paraspinal (ie, multifidus) muscle function and neuromuscular activation pattern is intramuscular electromyography (EMG). Previous studies have shown that the procedure does not significantly impact muscle function during activities involving low-level muscle contractions. However, it is currently unknown how muscular function and activation are affected during high-exertion contractions.Objective
To examine the effects of insertion and presence of fine-wire EMG electrodes in the lumbar multifidus on muscle strength, endurance, and activation profiles during high-exertion spinal extension muscle contractions.Design
Single-blinded, repeated measures intervention trial.Setting
University clinical research laboratoryParticipants
Twenty individuals between the ages of 18-40 free of recent and current back pain.Methods
Muscle performance was assessed during 3 conditions (with [WI] and without [WO] presence of intramuscular electrodes, and insertion followed by removal [IO]). Isometric spinal extension strength was assessed with a motorized dynamometer. Muscle endurance was assessed using the Sorensen test with neuromuscular activation profiles analyzed during the endurance test.Main Outcome Measurements
Spinal extensor muscle strength, endurance, and activation.Results
Our data showed no significant difference in isometric strength (P = .20) between the 3 conditions. A significant difference in muscle endurance was found (P = .03). Post hoc analysis showed that the muscle endurance in the IO condition was significantly higher than the WO condition (161.3 ± 58.3 versus 142.1 ± 48.2 seconds, P = .04), likely due to a learning effect. All 3 conditions elicited minimal pain (range 0-4/10) and comparable muscle activation profiles.Conclusion
Our findings suggested the sonographically guided insertion and presence of fine-wire intramuscular EMG electrodes in the lumbar multifidus muscles had no significant impact on spinal extension muscle function. This study provides evidence that implementing intramuscular EMG does not affect muscle performance during high-exertion contractions in individuals with no current back pain.Level of Evidence

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20.
