Anders C, Wenzel B, Scholle HC. Activation characteristics of trunk muscles during cyclic upper-body perturbations caused by an oscillating pole.
Objective
To evaluate the effect of a new device on trunk muscle activation.Design
Cross-sectional survey of trunk muscle activation characteristics.Setting
Physiologic laboratory at university institute.Participants
Thirty healthy subjects (15 men, 15 women) were recruited from a university campus.Interventions
A simple flexible pole that applies rapidly alternating forces on the trunk when set into motion was used. The device was held horizontally in both hands, in front of the body. It was used at 3 different oscillation frequencies (3, 3.5, 4.5Hz), in horizontal and vertical plane, respectively.Main Outcome Measures
Surface electromyography of 5 trunk muscles was measured and the data were normalized according to relative cycle time. Time dependent (amplitude curve) and time independent (mean amplitude over cycle) parameters were used for analysis.Results
Rectus abdominis and external oblique muscle amplitudes were directly proportional with oscillation frequency (analysis of variance), and these effects were independent of sex. Multifidus amplitude levels were subject to oscillation plane with increased levels for vertical oscillation in men but not in the women. All abdominal muscles exhibited continuous activation pattern, independent of oscillation plane. Back muscles changed from a continuous activation in horizontal plane into similarly phasic patterns in vertical oscillation plane. The occurring amplitude peak moved forward in relative cycle with increasing oscillation frequency.Conclusions
Back muscle activation patterns were subject to oscillation plane. Abdominal muscle activation was independent from oscillation frequency and oscillation plane. These normative data may be used to identify disturbed trunk muscle coordination patterns and to control success of functional restoration during rehabilitation interventions of back pain patients. 相似文献2.

Yoon JS, Hong S-J, Kim B-J, Kim SJ, Kim JM, Walker FO, Cartwright MS. Ulnar nerve and cubital tunnel ultrasound in ulnar neuropathy at the elbow.
Objective
To determine the accuracy of the ultrasonographic measurement of ulnar nerve to cubital tunnel area for diagnosis of ulnar neuropathy at the elbow.Design
Patients with confirmed ulnar neuropathy at the elbow and normative, healthy volunteers were evaluated with high-resolution ultrasound. The cross-sectional areas (CSAs) of the ulnar nerve and cubital tunnel were measured with the elbow extended and flexed, and results from the 2 groups were compared.Setting
Electromyography laboratory and radiology department of a tertiary care center.Participants
Twenty-seven patients with ulnar neuropathy at the elbow and 20 controls.Interventions
Not applicable.Main Outcome Measure
The ratio of ulnar nerve to cubital tunnel CSA with the elbow flexed.Results
The ulnar nerve, with the elbow flexed, was larger in those with ulnar neuropathy at the elbow, and this group also had larger cubital tunnels than did controls. In those with ulnar neuropathy at the elbow, the ratio of the ulnar nerve to cubital tunnel was .31, and in the controls it was .32, which was not significantly different (P=.89).Conclusions
The ratio of ulnar nerve to cubital tunnel did not differentiate those with ulnar neuropathy at the elbow from controls. 相似文献3.

Tarnanen SP, Ylinen JJ, Siekkinen KM, Mälkiä EA, Kautiainen HJ, Häkkinen AH. Effect of isometric upper-extremity exercises on the activation of core stabilizing muscles.
Objective
To evaluate whether isometric exercises for the upper extremities could sufficiently activate core stabilizing muscles to increase muscle strength.Design
Cross-sectional study.Setting
Department of physical medicine and rehabilitation at a Finnish hospital.Participants
Healthy adult women (N=20).Interventions
Not applicable.Main Outcome Measures
Peak isometric strength of the back and abdominal muscles was measured and relative loading in 5 test exercises was evaluated by surface electromyography.Results
The rectus abdominis and obliquus externus abdominis were activated to the greatest degree in a bilateral shoulder extension exercise and the average surface electromyographic activity was 114% and 101% compared with the amplitude elicited during the maximal isometric trunk flexion exercise. Horizontal shoulder extension elicited the greatest activation of the longissimus and multifidus muscles. In this exercise, the activity levels of the left side multifidus and longissimus muscles were 84% and 69%, respectively, compared with the level of activity elicited during trunk extension.Conclusions
Of all the exercises studied, bilaterally performed isometric shoulder extension and unilaterally performed horizontal shoulder extension elicited the greatest levels of activation of the trunk musculature. Thus, it can be assumed that these exercises elicit sufficient levels of contraction of the trunk muscles for the development of their endurance and strength characteristics in rehabilitation. 相似文献4.

Matthys K, Smits M, Van der Geest JN, Van der Lugt A, Seurinck R, Stam HJ, Selles RW. Mirror-induced visual illusion of hand movements: a functional magnetic resonance imaging study.
Objective
To identify neural networks associated with the use of a mirror to superimpose movement of 1 hand on top of a nonmoving contralateral hand (often referred to as mirror therapy or mirror-induced visual illusion).Design
A functional magnetic resonance imaging (fMRI) study of mirror-induced visual illusion of hand movements using a blocked design in a 1.5T magnetic resonance imaging scanner. Neural activation was compared in a no-mirror experiment and a mirror experiment. Both experiments consisted of blocks of finger tapping of the right hand versus rest. In the mirror experiment, movement of the left hand was simulated by mirror reflection of right hand movement.Setting
University medical center.Participants
Eighteen healthy subjects.Interventions
Not applicable.Main Outcome Measures
Differences in fMRI activation between the 2 experiments.Results
In the mirror experiment, we found supplementary activation compared with the no-mirror experiment in 2 visual areas: the right superior temporal gyrus (STG) and the right superior occipital gyrus.Conclusions
In this study, we found 2 areas uniquely associated with the mirror-induced visual illusion of hand movements: the right STG and the right superior occipital gyrus. The STG is a higher-order visual region involved in the analysis of biological stimuli and is activated by observation of biological motion. The right superior occipital gyrus is located in the secondary visual cortex within the dorsal visual stream. In the literature, the STG has been linked with the mirror neuron system. However, we did not find activation within the frontoparietal mirror neuron system to support further a link with the mirror neuron system. Future studies are needed to explore the mechanism of mirror induced visual illusions in patient populations in more detail. 相似文献5.

You JH, Saliba S, Saliba E. Use of a combination of ankle pressure and SENSERite system to treat older adults with impaired ankle proprioception: a single-blind experimental study.
Objective
To investigate the effects of a combination of visual biofeedback and ankle pressure on ankle position sense in elderly adults with and without impaired ankle joint position sense (JPS).Design
Independent 2 × 3 factorial design with an experimenter-blind study.Setting
University motion laboratory.Participants
Older adults (N=40) were recruited from local community centers. Among them, 21 elderly subjects had relatively normative score, whereas 19 subjects had impaired ankle position sense.Intervention
Both the normative and impaired elderly subjects underwent either ankle JPS visual feedback training alone or a combination of ankle JPS visual feedback training and circumferential ankle pressure for one 30-minute training session.Main Outcome Measures
The outcome measures included ankle JPS errors measured in absolute constant error (ACE) and variable error (VE) during standing at pretest, posttest, and 1-week follow-up test. A separate repeated measures analyses of variance was performed to evaluate the differential training effects on ACE and VE, respectively. The Pearson chi-square test and Bonferroni test were performed. Significance was assigned at P less than .05 for all analyses.Results
Regardless of intervention conditions, older adults with and without ankle position sense impairment showed immediate treatment benefits, which relatively remained stable even at the follow-up test. These effects were reflected in significant improvements of JPS accuracy and consistency (P<.05).Conclusions
Our findings may suggest that both interventions were equally effective in increasing ankle JPS accuracy and consistency in older adults with and without impairments, and therapeutic effects lasted for a week, reflecting long-term effect. 相似文献6.

Lee AS, Cholewicki J, Reeves NP, Zazulak BT, Mysliwiec LW. Comparison of trunk proprioception between patients with low back pain and healthy controls.
Objective
To determine whether proprioceptive impairments exist in patients with low back pain (LBP). We hypothesized that patients with LBP would exhibit larger trunk proprioception errors than healthy controls.Design
Case-control study.Setting
University laboratory.Participants
24 patients with nonspecific LBP and 24 age-matched healthy controls.Interventions
Not applicable.Main Outcome Measures
We measured trunk proprioception in all 3 anatomical planes using motion perception threshold, active repositioning, and passive repositioning tests.Results
LBP patients had significantly greater motion perception threshold than controls (P<.001) (1.3±0.9° vs 0.8±0.6°). Furthermore, all subjects had the largest motion perception threshold in the transverse plane (P<.001) (1.2±0.7° vs 1.0±0.8° for all other planes averaged). There was no significant difference between LBP and healthy control groups in the repositioning tasks. Errors in the active repositioning test were significantly smaller than in the passive repositioning test (P=.032) (1.9±1.2° vs 2.3±1.4°).Conclusions
These findings suggest that impairments in proprioception may be detected in patients with LBP when assessed with a motion perception threshold measure. 相似文献7.

Stoelb BL, Carter GT, Abresch RT, Purekal S, McDonald CM, Jensen MP. Pain in persons with postpolio syndrome: frequency, intensity, and impact.
Objective
To describe the frequency, intensity, and impact of pain in persons with postpoliomyelitis syndrome (PPS).Design
Retrospective, cross-sectional survey.Setting
Community-based survey.Participants
Convenience sample of people with PPS.Interventions
Not applicable.Main Outcome Measures
Overall intensity and duration of pain, pain sites, pain interference, pain treatments, and relief provided by pain treatments.Results
A total of 91% (n=57) of the study participants (N=63) reported pain. The most frequently reported pain sites were the shoulders, lower back, legs, and hips. Participants reported pain intensity to be the greatest in the knees, legs, wrists, lower back, and head. Pain interfered most with sleep and with activities requiring a high level of musculoskeletal involvement. Respondents also reported pain problems that were more severe than those of the general population and than those of a sample of people with multiple sclerosis. Many treatments had been tried previously for pain, but continued use of treatments was reported by relatively few participants at the time of the survey.Conclusions
The findings indicate that pain is a persistent and common problem in persons with PPS, highlighting the need for effective and accessible pain treatments for this population. 相似文献8.
Objective
To evaluate if unconjugated bilirubin (UB) inhibits C1 esterase activity.Design and methods
Esterase activity was evaluated by C1-mediated hydrolysis of N-acetyl-l-tyrosine ethyl ester, and binding of UB to C1r and C1s was assessed by dot-blot analysis.Results
UB inhibited C1 enzymatic activity. C1r, C1s and human serum albumin bound [14C]-UB to a similar extent.Conclusions
UB inhibits C1 esterase activity, apparently due to a direct pigment-protein interaction. This could explain the inhibitory action of UB on complement activation. 相似文献9.

Miller LA, Lipschutz RD, Stubblefield KA, Lock BA, Huang H, Williams III TW, Weir RF, Kuiken TA. Control of a six degree of freedom prosthetic arm after targeted muscle reinnervation surgery.
Objectives
To fit and evaluate the control of a complex prosthesis for a shoulder disarticulation-level amputee with targeted muscle reinnervation.Design
One participant who had targeted muscle reinnervation surgery was fitted with an advanced prosthesis and his use of this device was compared with the device that he used in the home setting.Setting
The experiments were completed within a laboratory setting.Participant
The first recipient of targeted muscle reinnervation: a bilateral shoulder disarticulation-level amputee.Interventions
Two years after surgery, the subject was fitted with a 6 degree of freedom (DOF) prosthesis (shoulder flexion, humeral rotation, elbow flexion, wrist rotation, wrist flexion, and hand control). Control of this device was compared with that of his commercially available 3-DOF system (elbow, wrist rotation, and powered hook terminal device).Main Outcome Measure
In order to assess performance, movement analysis and timed movement tasks were executed.Results
The subject was able to independently operate all 6 arm functions with good control. He could simultaneously operate 2 DOF of several different joint combinations with relative ease. He operated up to 4 DOF simultaneously, but with poor control. Work space was markedly increased and some timed tasks were faster with the 6-DOF system.Conclusions
This proof-of-concept study shows that advances in control of shoulder disarticulation-level prostheses can improve the quality of movement. Additional control sources may spur the development of more advanced and complex componentry for these amputees. 相似文献10.

Objectives
To assess the activities of paraspinal and abdominal muscles during therapeutic exercises for the treatment of patients with nonspecific chronic low back pain (CLBP), and to study the effects of active physical rehabilitation on these activities.Design
A cross-sectional study comparing muscle activities during 18 stabilization exercises, and a prospective follow-up of patients with CLBP during rehabilitation.Setting
Rehabilitation clinic in university hospital in Finland.Participants
Nine volunteers (5 men, 4 women) aged 27 to 58 years.Intervention
Three months of active outpatient rehabilitation (4 to 6 times in a rehabilitation clinic, supplemented with self-motivated exercise at home) supervised by a physiotherapist.Main outcome measures
Surface electromyography was recorded bilaterally from L5 level paraspinal, rectus abdominis, and obliquus externus abdominis muscles. The recorded signal was averaged and normalized to the maximal electromyographic amplitude obtained during the maximal voluntary contraction. The measurements were taken before and after the exercise treatment period.Results
CLBP patients showed variable trunk muscle activity patterns during the different therapeutic exercises, similar to those that we reported earlier in healthy subjects. The maximal trunk isometric extension (pre, 147.3±75.9Nm; post, 170.1±72.3Nm) and flexion (pre, 72.0±37.9Nm; post, 93.5±42.5Nm) torques did not show a significant changes during the exercise period. However, trunk rotation-flexion torque (pre, 52.9±26.5Nm; post, 82.4±65.8Nm) increased significantly (35.8%) after the exercise period (P<.05). The corresponding maximal electromyographic amplitudes of back and abdominal muscles remained unchanged. Disability, as assessed by visual analog scale and Oswestry Disability Index, did not change.Conclusions
The CLBP patients performed therapeutic exercises with similar abdominal and back extensor muscle activities in the same way as the healthy subjects in our earlier studies. In this study, active physical rehabilitation had no effect on the abdominal and back muscle activities or on pain and functional disability indices. 相似文献11.

Background
Shoulder pain is a common clinical problem, and numerous tests are used to diagnose structural pathology.Objectives
To systematically review the reliability of physical examination procedures used in the clinical examination of patients with shoulder pain.Data sources
MEDLINE, PEDro, AMED, PsychInfo, Cochrane Library (2009) and CINAHL were searched from the earliest record on the database to June 2009.Study eligibility criteria
Reliability studies that included any patients with shoulder pain were analysed for their quality and reliability results.Study appraisal and synthesis methods
Pre-established criteria were used to judge the quality of the studies (high quality >60% methods score) and satisfactory levels of reliability (kappa or intraclass correlation coefficient ≥0.85, sensitivity analysis 0.70). A qualitative synthesis was performed based on levels of evidence.Results
Thirty-six studies were included with a mean methods score of 57%. Seventeen studies were deemed to be of high quality; high-quality studies were less likely to meet the pre-agreed level of reliability. The majority of studies indicated poor reliability for all procedures investigated.Limitations
Overall, the evidence regarding reliability was contradictory.Conclusions and implications
There is no consistent evidence that any examination procedure used in shoulder assessments has acceptable levels of reliability. Alternate methods of classification which are reliable should be used to classify patients with shoulder problems. 相似文献12.

Nijs J, Roussel N, Vermuelen K, Souvereyns G. Scapular positioning in patients with shoulder pain: a study examining the reliability and clinical importance of 3 clinical tests.
Objective
To examine the interobserver reliability, internal consistency, and clinical importance of 3 clinical tests for the assessment of scapular positioning in patients with shoulder pain.Design
Prospective repeated-measures design.Setting
Private practices for physical therapy and hospital outpatient physical therapy divisions.Participants
Twenty-nine patients with shoulder pain who were diagnosed by a physician as having a shoulder disorder.Interventions
Not applicable.Main Outcome Measures
Study participants filled in a visual analog scale for pain and the Shoulder Disability Questionnaire. Next, 2 assessors performed the following tests: measurement of the distance between the posterior border of the acromion and the table, measurement of the distance from the medial scapular border to the fourth thoracic spinous processes, and the lateral scapular slide test.Results
The interobserver reliability coefficients were greater than .88 (intraclass correlation coefficients) for the measurement of the distance between the posterior border of the acromion and the table, were greater than .50 for the measurement of the distance from the medial scapular border to the fourth thoracic spinous processes, and were greater than .70 for the lateral scapular slide test. The Cronbach α coefficient for internal consistency for all tests was .88. No associations between the outcome of the tests and self-reported pain severity or disability were found.Conclusions
These data provide evidence favoring the interobserver reliability of 2 of 3 tests for the assessment of scapular positioning in patients with shoulder pain. The clinical importance of the tests’ outcomes, however, is questionable. 相似文献13.

Objectives
The aim of this study was to validate the Lipochip® genetic diagnostic platform by assessing effectiveness, sensitivity, specificity and costs for the identification of patients with familial hypercholesterolemia (FH) in Spain. This platform includes the use of a DNA micro array, the detection of large gene rearrangements and the complete resequencing of the low-density lipoprotein receptor gene.Design and methods
DNA samples of patients with clinically diagnosed FH were analyzed for mutations by application of the Lipochip® platform. Results obtained were confirmed by DNA sequencing and MLPA analysis by two other, independent laboratories.Results
Of 808 patients tested, Lipochip® detected a mutation in 66% of the cases and of these 78% were detected by the micro array. A specificity of 99.5% at a sensitivity of 99.8% was reached. A positive test result could be reported within 22 days after start of analysis. The total average screening costs of $ 350 per case were significantly lower compared to other existing screening programs.Conclusion
Lipochip® provides a reliable, fast and cheap alternative for the genetic testing of patients with clinically diagnosed FH. 相似文献16.
Background:
Radiation rectitis is a major problem associated with high-doseirradiation used for pelvic malignancies.Objective:
The aim of this study was to investigate the possible protectiveeffect of mesalamine against irradiation-induced oxidative tissue damage in an experimental model.Methods:
Three groups of female Sprague Dawley rats were assigned to receive treatment as follows: mesalamine enema (60 mg/mL) BID + irradiation (IR) was given to the mesalamine + IR group, and isotonic saline enema BID + irradiation to the control group. Treatments were given from the day before irradiation until euthanization (72 hours after the irradiation). Sham control rats received isotonic saline enema BID but no irradiation. On the third day of treatment, all animals were euthanized, and reduced glutathione (GSH) level, malondialdehyde (MDA) level, and myeloperoxidase (MPO) activity were measured in the rectal, intestinal, and hepatic tissue of the rats.Results:
The sham group comprised 7 rats; the control and mesalamine + IRgroups, 16 rats each. The median GSH levels of rectal and intestinal specimens were lower in the control group compared with the sham group. The rectal and intestinal MDA levels were higher in the control group compared with the sham group. The rectal and intestinal MPO activities were higher in the control group compared with the sham group. All of these differences were statistically significant (P < 0.001) and indicated oxidative stress. With the topical application of mesalamine, the GSH and MDA levels and MPO activities were similar to those of the sham group.Conclusion:
The pelvic irradiation of rats caused oxidative rectal, intestinal,and hepatic tissue damage, which was ameliorated with the use of mesalamine. 相似文献17.

Massie C, Malcolm MP, Greene D, Thaut M. The effects of constraint-induced therapy on kinematic outcomes and compensatory movement patterns: an exploratory study.
Objective
To determine changes in kinematic variables and compensatory movement patterns of survivors of stroke completing constraint-induced therapy (CIT).Design
Pre-post, case series.Setting
Clinical rehabilitation research laboratory.Participants
Men (n=7) and women (n=3) with unilateral stroke occurring at least 9 months prior to study entry with moderate, stable motor deficits.Intervention
Participants completed 10 consecutive weekdays of CIT for 6 hours a day comprised of trainer-supervised, functionally based activities using massed practice.Main Outcome Measures
Kinematic measures included movement time, average velocity, trajectory stability, shoulder abduction, and segmental contribution. Functional measures included Wolf Motor Function Test (WMFT) performance time and functional ability scores and Motor Activity Log (MAL) “how-well” scores. All measures were administered before and after the 2-week CIT intervention.Results
Movement time, average velocity, and trajectory stability significantly improved after CIT. Participants used more shoulder flexion to reach after CIT, but also demonstrated increased compensatory shoulder abduction. Functional scores also significantly improved, including WMFT performance time and functional ability and MAL scores. There was no change in trunk movement or amount of elbow extension.Conclusions
CIT improved motor capacities in the hemiparetic arm as reflected in the functional outcomes and in some kinematic measures. Participants' reliance on common compensatory movements was not beneficially affected by CIT. The results of this study demonstrate that while functional capacity and some movement strategies in the hemiparetic arm improve after CIT, participants may not overcome their reliance on common compensatory movement patterns. Based on these findings, this study suggests that CIT may encourage subjects to generate movement through compensatory and/or synergy-dominated movement rather than promote the normalization of motor control. This outcome highlights the need to develop CIT further as an intervention that improves functional capacity and more normative movement strategies. 相似文献18.

Objective
To determine whether a patient's presenting psychometric scores affect the findings of a pressure and injection speed-controlled manometric lumbar diskography in patients with chronic low back pain (CLBP).Design
A prospective, correlation-based, investigative study.Setting
Free-standing ambulatory spine surgery center.Participants
Two hundred sixty-three disks from 81 patients (54 men, 27 women).Intervention
Diskography was performed using pressure and injection speed-controlled techniques. The patients were divided into psychometric subgroups (normal, at risk, abnormal) according to the Distress and Risk Assessment Method (DRAM).Main Outcome Measures
The diskography findings on each psychometric DRAM subgroup were evaluated.Results
Across the individual psychometric categories, the positive rates of diskography in the normal, at-risk, and abnormal subgroups were 75.0% (9/12), 59.5% (25/42), and 70.4% (19/27), respectively (P>.05). The mean numeric rating scores of pain at 15 and 50psi above the opening pressure were similar in the 3 psychometric subgroups. There was no correlation between the diskography results and the psychometric subgroupings.Conclusions
In patients with CLBP, there is no correlation between the presenting psychometric DRAM score and the findings from pressure and injection speed-controlled manometric lumbar diskography. 相似文献19.
Yeh C-Y, Tsai K-H, Su F-C, Lo H-C. Effect of a bout of leg cycling with electrical stimulation on reduction of hypertonia in patients with stroke.
Objectives
To evaluate whether a bout of leg cycling in patients with stroke reduces muscle tone and to determine whether neuromuscular functional electrical stimulation (FES) to the affected leg during cycling is more effective than cycling without FES.Design
Within-subject comparison.Setting
University hospital.Participants
Patients with stroke (N=16; age range, 42-72y; <8wk poststroke) with hypertonia in the affected leg.Interventions
Subjects' affected leg (1) performed cycling exercise with the assistance of FES (assisted-cycling session) and (2) performed cycling exercise without the assistance of FES (nonassisted-cycling session). Subjects sat in a specially designed wheelchair positioned on a resistance-free roller for each 20-minute session.Main Outcome Measures
Changes in muscle tone pre- and posttest session were compared by using the Modified Ashworth Scale and the pendulum test (relaxation index and peak velocity).Results
Modified Ashworth Scale scores were significantly lower (P<.05) and relaxation index and peak velocity values were significantly higher (P<.05) after both sessions. Changes in Modified Ashworth Scale scores, relaxation index, and peak velocity values showed a significant (P<.05) difference between the 2 sessions, and assisted cycling reduced hypertonia more than nonassisted cycling.Conclusions
The hypertonia of patients with stroke showed a significant decrease immediately after a bout of leg-cycling exercise. FES-assisted leg cycling was better than nonassisted cycling for reducing hypertonia. 相似文献20.
