IntroductionThe aim of this study was to evaluate the intra and inter-rater and inter-analyzer reliability of neuromuscular variables and functional tests.MethodsCross-sectional crossover design. Two independent raters and analyzers evaluated twenty-two healthy subjects. Knee-extensor strength was assessed from three maximal voluntary isometric contractions. Muscle activation was obtained from the vastus lateralis (VL), rectus femoris (RF), and vastus medialis (VM) muscles. VL and RF muscles’ architecture [fascicle length (FL), pennation angle (PA), muscle thickness (MT)] was obtained at rest by ultrasound. The time from five sit-to-stand (STS) trials, and the distance from the 6-min walk test (6MWT) were obtained. Intraclass correlation coefficient was determined and classified as strong (r = 0.75–1.00), moderate (r = 0.40–0.74), and weak (r < 0.40).ResultsStrong intra-rater reliability values were observed for strength (r = 0.97), muscle activation [VL (r = 0.91); RF (r = 0.92); VM (r = 0.80)], VL [FL (r = 0.90); PA (r = 0.94); MT (r = 0.99)] and RF [MT (r = 0.85)] muscle architecture, STS (r = 0.95), and 6MWT (r = 0.98). Inter-rater reliability also presented strong values for strength (r = 0.97), muscle activation [VL (r = 0.94); RF (r = 0.79); VM (r = 0.78)], muscle architecture VL [PA (r = 0.81) and MT (r = 0.88)] and RF [MT (r = 0.80)], STS (r = 0.93), and 6MWT (r = 0.98). A moderate correlation VL muscle architecture [FL (r = 0.69)]. Inter-analyzer muscle architecture reliability presented strong VL [FL (r = 0.77); PA (r = 0.76); MT (r = 0.91)] and RF [MT (r = 0.99)].ConclusionThe high intra and inter-rater and inter-analyzer reliability values for most variables is evidence that they can be used for clinical evaluation. Muscle architecture might need a longer training period by different raters and analyzers to increase reliability. 相似文献

This study investigated the validity and reliability of measuring patellar tendon (PT) cross-sectional area (CSA) using magnetic resonance imaging (MRI) and ultrasound (US) imaging. Nineteen healthy participants (10 women, 9 men) participated in three imaging sessions of the PT, once via MRI and twice via US, with image acquisition conducted by two raters, one experienced (rater 2) and one inexperienced (rater 1). All PT segmentations were analyzed by both raters. The validity of US-derived estimates of PT CSA against MRI estimates was analyzed using linear regression. Within-day reliability of US and MRI measurements and between-day reliability of US measurements were quantified using typical error (TE) and intra-class correlation coefficients (ICC3,1). There was good agreement between US- and MRI-derived estimations of PT CSA (standard errors of the estimate of 3.3 mm2 for rater 1 and 2.6 mm2 for rater 2; Pearson's r = 0.97 and 0.98 for raters 1 and 2, respectively). Within-session reliability for estimations of total PT CSA from US and MRI were excellent (ICC3,1 >0.95, coefficient of variation [CV] <4.1%, TE = 1.3–3.6 mm2. Between-day reliability for US was excellent (ICC3,1 >0.97, CV <2.7%, TE = 1.6–2.3 mm2), with little difference between raters. These findings suggest that MRI and US both provide reliable estimates of PT CSA and that US can provide a valid measure of PT CSA. 相似文献

IntroductionAlthough the pressure biofeedback unit (PBU) is used for muscular assessment and training, there is little evidence of its reproducibility and repeatability.ObjectiveThis study aims to assess intra- and inter-rater reproducibility and repeatability of the PBU in the assessment of the transverse abdominal (TrA), internal oblique (IO), low back multifidi, and deep neck flexors (DNF).MethodsFifty individuals had three muscular groups tested: TrA/IO, lower back multifidi, and DNF. For repeatability, one rater did three consecutive measures; for intra-rater reproducibility the same rater did two measures with seven-day intervals, and for inter-rater reproducibility, three raters, on the same day, did the measures. Data were analyzed with: Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), and Minimal Detectable Change (MDC). (α = 0,05).ResultsRepeatability: TrA/IO (ICC = 0.847), Multifidi (ICC = 0.860), DNF (ICC = 0.831). Inter-rater reproducibility: TrA/IO (ICC = 0.876), Multifidi (ICC = 0.508), DNF (ICC = 0.442). Intra-rater reproducibility: TrA/IO (ICC = 0.747), Multifidi (ICC = 0.293), DNF (ICC = 0.685). Except for Multifidi, all the SEM values were less than 10 mmHg and the MDC values were less than 15 mmHg.ConclusionsThe PBU can be used with reliability by different evaluators, although the evaluation of multifidi is not indicated. 相似文献

BackgroundFunctional performance tests are inexpensive, accessible, and easy to apply tools that can be used to help practitioners in daily decision making process. The purpose of this study was to evaluate the reliability and validity of the One Arm Hop Test (OAHT) and Seated Medicine Ball Throw Test (SBMT) in young adults.MethodsCross-sectional study with a sample consisted of 59 young adults. The subjects performed the OAHT and SMBT in two moments separated by seven days and by two examiners. The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) was performed at the second moment. The time in OAHT, distance in SMBT, mean number of touches, normalized score, and power of the CKCUEST were measured. Reliability was determined using Intraclass Correlation Coeficient (ICC) and Bland-Altman Plots. Validity was assessed via Pearson's Correlation Coefficient (r) between these tests and CKCUEST.ResultsWe found good reliability of the OAHT between different raters (dominant limb – ICC = 0.83; non-dominant limb – ICC = 0.80) and moderate reliability between the same rater (dominant limb – ICC = 0.63; non-dominant limb – ICC = 0.62). In the SMBT we found good reliability inter-examiner (ICC = 0.84) and intra-examiner (ICC = 0.77). Low to moderate correlations with the CKCUEST were found (r < 0.70; p < 0.05).ConclusionsThe OAHT and the SMBT show moderate/good reliability intra and inter-examiner, however these tests are poorly correlated with CKCUEST. The SMBT presented higher values of ICC than OAHT. A combination of the SMBT and CKCUEST is recommended in clinical practice. 相似文献

BackgroundPractitioners traditionally use observation to classify the position of patients' anatomical landmarks. This information may contribute to diagnosis and patient management.ObjectivesTo calculate a) Inter-rater reliability of categorising the sagittal plane position of four anatomical landmarks (lateral femoral epicondyle, greater trochanter, mastoid process and acromion) on side-view photographs (with landmarks highlighted and not-highlighted) of anonymised subjects; b) Intra-rater reliability; c) Individual landmark inter-rater reliability; d) Validity against a ‘gold standard’ photograph. Design: Online inter- and intra-rater reliability study.SubjectsPhotographed subjects: convenience sample of asymptomatic students; raters: randomly selected UK registered osteopaths.Methods40 photographs of 30 subjects were used, a priori clinically acceptable reliability was ≥0.4. Inter-rater arm: 20 photographs without landmark highlights plus 10 with highlights; Intra-rater arm: 10 duplicate photographs (non-highlighted landmarks). Validity arm: highlighted landmark scores versus ‘gold standard’ photographs with vertical line. Research ethics approval obtained.RatersOsteopaths (n = 48) categorised landmark position relative to imagined vertical-line; Gwet's Agreement Coefficient 1 (AC1) calculated and chance-corrected coefficient benchmarked against Landis and Koch's scale; Validity calculation used Kendall's tau-B.ResultsInter-rater reliability was 'fair' (AC1 = 0.342; 95% confidence interval (CI) = 0.279–0.404) for non-highlighted landmarks and 'moderate' (AC1 = 0.700; 95% CI = 0.596–0.805) for highlighted landmarks. Intra-rater reliability was 'fair' (AC1 = 0.522); range was ‘poor’ (AC1 = 0.160) to ‘substantial’ (AC1 = 0.896). No differences were found between individual landmarks. Validity was ‘low’ (TB = 0.327; p = 0.104).ConclusionBoth inter- and intra-rater reliability was ‘fair’ but below clinically acceptable levels, validity was ‘low’. Together these results challenge the clinical practice of using observation to categorise anterio-posterior landmark position. 相似文献

BackgroundThe purpose of this study is to compare the effects of stretching methods on flexibility, muscle activation, and pressure pain threshold in ballet dancers, and to suggest an effective stretching method.MethodsThirty-three ballet dancers were randomized to the static stretching group (n = 11), muscle energy technique stretching group (n = 11), and vibration-assisted stretching group (n = 11). The angle of hip joint extension in arabesque, activation of the rectus femoris in devéloppé, and pressure pain threshold on the rectus femoris in the sitting position were measured to compare the effects of the different stretching methods. Paired t-test was used to compare the pre and post-intervention findings within each group and one-way analysis of variance to compare the difference in the amount of changes among the groups.ResultsThe hip joint extension angles increased in all stretching methods (p < 0.05); however, vibration-assisted stretching and muscle energy technique stretching were more effective than static stretching (p < 0.05). The activation of the rectus femoris decreased in all groups (p < 0.05); however the muscle energy technique stretching group and vibration-assisted stretching group showed a significant decrease in muscle activation compared with the static stretching group (p < 0.05). The pressure pain threshold significantly improved only in the static stretching group (p < 0.05); and vibration-assisted stretching group (p < 0.05).ConclusionsCompared with static stretching and muscle energy technique stretching, vibration-assisted stretching is a beneficial method for improving flexibility, muscle activation, and pressure pain threshold in ballet dancers. 相似文献

ObjectiveMeasuring muscle quantity and quality is very important because the loss of muscle quantity and quality is associated with several adverse effects specifically in older people. Ultrasound is a method widely used to measure muscle quantity and quality. One problem with ultrasound is its limited field of view, which makes it impossible to measure the muscle quantity and quality of certain muscles. In this study, we aimed to evaluate the intra- and inter-rater reliability of extended-field-of-view (EFOV) ultrasound for the measurement of muscle quantity and quality in nine muscles of the limbs and trunk.MethodsTwo examiners took two ultrasound EFOV images with a linear probe from each of the muscle sites. The intraclass correlation coefficient (ICC) was used, and the standard error of measurement and coefficient of variation were calculated.ResultsIntra-rater reliability was good to excellent (ICC = 0.2–1.00) for all muscle measurements. The inter-rater reliability for most of the muscle measurements was good to excellent (ICC = 0.82–0.98). Inter-rater reliability was moderate (0.58–0.72) for some muscle quantity measurements of the tibialis anterior, gastrocnemius, rectus femoris, biceps femoris and triceps brachii muscles.ConclusionMuscle quantity and quality can be measured reliably using EFOV US. 相似文献

BackgroundInfiltration of muscle with non-lean tissue, such as fat, reduces muscle quality. Ultrasound captures muscle quality through measurement of echogenicity. Given the potential implications of quadriceps muscle quality on physical function, particularly in knee osteoarthritis, the purpose of this study was to investigate the relationship between echogenicity, muscle thickness and subcutaneous fat thickness with the clinical severity of osteoarthritis.MethodsThirty-one women with clinical knee osteoarthritis participated. Rectus femoris and vastus lateralis echogenicity, muscle thickness and subcutaneous fat thickness were measured from ultrasound images of the most symptomatic knee. Clinical severity of osteoarthritis was characterized with pain, self-reported function, six-minute walk test, and knee extensor strength. Correlation coefficients were calculated between muscle and fat architecture outcomes (muscle quality, muscle and fat thicknesses) and osteoarthritis clinical severity outcomes.FindingsData from 25 women were of sufficient quality for analysis. Echogenicity (muscle quality) related to the six-minute walk test for both rectus femoris (r = −0.52, p = 0.02) and vastus lateralis (r = −0.74, p = 0.004), with poorer muscle quality related to lower mobility. Subcutaneous fat thickness was related to the six-minute walk test (rectus femoris, r = −0.61, p = 0.0012; vastus lateralis, r = −0.73, p = 0.003) and strength (rectus femoris, r = −0.46, p = 0.02; vastus lateralis, r = −0.59, p = 0.03). Muscle thickness was not related to any severity outcomes.InterpretationMuscle quality, rather than thickness, is associated with mobility performance in women with knee osteoarthritis. Thus, interventions for osteoarthritis that specifically target muscle quality, rather than size, should be explored. 相似文献

IntroductionMedical professionals frequently encounter forward head postures (FHP) in the treatment of cervical spine pain. In the clinical setting, FHP measurements are often described subjectively using the phrase, “patient demonstrates forward head posture.” There are reliable tools that can objectively measure FHP, but they are not frequently used in the clinical setting on a regular basis because the tools are unavailable, inconvenient or overly time-consuming. The objective of this study was to confirm if FHP can be reliably measured using a novel posture-measuring device. The Posture Measuring Device (PMD) was designed to quickly obtain objective measurements of FHP in the outpatient clinical setting. A pilot study demonstrated good to excellent reliability in intra-rater (test-retest) measurements and good interrater reliability using two first-year Doctor of Physical Therapy Students as raters. This study is to confirm that the PMD is able to provide intra-rater and interrater reliability using two physical therapists and two second-year Doctor of Physical Therapy students to obtain FHP measurements.MethodsTwenty-three college-aged subjects were measured individually using a PMD by a panel of four raters consisting of two physical therapists and two second-year physical therapy students to develop interrater reliability. Each rater measured each subject twice on two separate occasions to obtain a measure of intra-rater (relative) reliability.ResultsPearson Correlations demonstrate high intra-rater correlation with inconsistent interrater correlation. The average measured Intraclass Correlation Coefficient (ICC) was .822 with a 95% confidence interval indicating a high degree of reliability between the eight measurements performed on each subject. Cronbach's alpha results confirm the ICC findings of strong correlation among the eight raters (α = 0.87).Discussion and conclusionObjective measurement of forward head posture is valuable to document and monitor patient response to treatment. This study identifies a convenient and time-efficient method for measuring forward head in the clinical setting. The PMD demonstrated a high degree of reliability in intra-rater measurements of FHP. 相似文献

ObjectiveThe purpose of this study was to determine the accuracy and intrarater reliability of a palpatory protocol based on a combination of 3 palpatory methods to identify both the C7 spinous process (C7 SP) and the factors that affect the errors and inaccuracy of palpation.MethodsTwenty-five women between the ages of 18 and 60 years were submitted to a palpation protocol of the C7 SP, and a radiopaque marker was fixed on the skin at the possible location of the vertebrae. A radiograph and a photograph of the cervical spine were obtained in the same posture by a first rater. A second rater performed the same palpation protocol and took a second photograph. The accuracy and measurement error of the palpation protocol of C7 SP were assessed through radiographic images. The inter-rater reliability was estimated by the interclass correlation coefficient and assessed using photographs of each rater. The Pearson's correlation coefficients (r), the Fisher exact test, and the χ2 test were used to identify the factors associated with the error and inaccuracy of palpation.ResultsAccuracy of the C7 palpation was 76% with excellent reliability (interclass correlation coefficient = 0.99). There was a moderate correlation between weight and the measurement of palpation error (r = –0.6; P = .003). One hundred percent of inaccuracy palpation was related to the increased soft-tissue thickness (P = .005) in the cervical region.ConclusionThe palpation protocol described in this study was accurate and presented excellent reliability in identifying the C7 SP. Increased weight and dorsocervical fat pad were associated to error and palpation inaccuracy, respectively. 相似文献

This investigation assessed the processer reliability of estimating muscle volume and echo-intensity of the rectus femoris, tibialis anterior and semitendinosus. The muscles of 10 typically developing children (8.15 [1.40] y) and 15 children with spastic cerebral palsy (7.67 [3.80] y; Gross Motor Function Classification System I = 5, II = 5, III = 5) were scanned with 3-D freehand ultrasonography. For the intra-processer analysis, the intra-class correlations coefficients (ICCs) for muscle volume ranged from 0.943–0.997, with relative standard errors of measurement (SEM%) ranging from 1.24%–8.97%. For the inter-processer analysis, these values were 0.853 to 0.988 and 3.47% to 14.02%, respectively. Echo-intensity had ICCs >0.947 and relative SEMs <4% for both analyses. Muscle volume and echo-intensity can be reliably extracted for the rectus femoris, semitendinosus and tibialis anterior in typically developing children and children with cerebral palsy. The need for a single processer to analyze all data is dependent on the size of the expected changes or differences. 相似文献

There is growing interest in evaluating body composition using routine clinical computed tomography (CT) scans; however, the validity of this technique in lung transplant patients has not been described. The study objectives were to determine the reliability of measuring fat compartments from thoracic CT and evaluate the validity of muscle and fat cross‐sectional area (CSA) from thoracic CT by comparing to bioelectrical impedance analysis (BIA). Thoracic CT scans from lung transplant assessments were obtained for analysis. Total thoracic muscle CSA, pectoral muscle CSA, subcutaneous adipose tissue (SAT), and mediastinal adipose tissue (MAT) were manually segmented by two independent raters. Reliability was analysed using intra‐class correlation coefficient (ICC). Correlations were determined between CT measures with fat‐free mass index (FFMI), body fat mass index (BFMI) and per cent body fat (%BF) from BIA; and anthropometrics [body mass index (BMI) and waist circumference (WC)]. High inter‐ and intra‐rater reliability were found for SAT and MAT (ICCs = 0.99). Pectoral and total muscle CSA were correlated with FFMI (r = .41, p = .003 and r = .57, p < .001, respectively). SAT was associated with whole‐body fat from BIA and with BMI and WC (r = .61 to .80, p < .001). MAT was associated with BMI (r = .58, p < .001) and WC (r = .61, p < .001). This study supports the reliability and validity of using thoracic CT to measure muscle and fat. Future studies are needed to investigate whether these CT‐based measures are predictive of clinical and post‐transplant outcomes in advanced lung disease. 相似文献

This study tests the inter- and intra-rater reliability of a new method of interpreting centre of gravity (COG) location results of the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) tested on the NeuroCOM Balance Master? (BM). Sixty-three women (40--80 years) were randomly selected from a cohort of 500 women from the Longitudinal Assessment of Women (LAW) study. Start location of COG, as provided diagrammatically in the BM test results, for each of the four tests (firm surface, eyes open and closed; foam surface, eyes open and closed) was subjectively allocated by two raters (blinded to one another) to one of nine location categories on two occasions separated by at least 2 weeks. Kappa (к) analysis of the data showed a substantial level of both inter-rater [к = 0.84 (95% CI = 0.82--0.86)] and intra-rater [rater 1 к = 0.78 (95% CI = 0.74--0.79), rater 2 к = 0.88 (95% CI = 0.86--0.90)] reliability. The strong inter- and intra-rater reliability of this new interpretation of COG location in the mCTSIB test on the BM suggests that this may be an additional reliable method for clinicians to interpret results from steady state balance tests on the BM. 相似文献

ObjectiveWe investigated ultrasound patterns of muscle involvement in different types of spinal muscular atrophy (SMA) and their correlation with functional status to determine the pattern of muscle compromise in patients with SMA and the potential role of ultrasound to evaluate disease progression.MethodsWe examined muscles (biceps brachii, rectus femoris, diaphragm, intercostals and thoracic multifidus) of 41 patients with SMA (types 1 to 4) and 46 healthy age- and sex-matched control individuals using B-mode ultrasound for gray-scale analysis (GSA), area (biceps brachii and rectus femoris) and diaphragm thickening ratio. Functional scales were applied to patients only. We analyzed ultrasound abnormalities in specific clinical subtypes and correlated findings with functional status.ResultsCompared with controls, patients had reduced muscle area and increased mean GSA for all muscles (p < 0.001), with an established correlation between the increase in GSA and the severity of SMA for biceps brachii, rectus femoris and intercostals (p = 0.03, 0.01 and 0.004 respectively) when using the Hammersmith Functional Motor Scale Expanded. Diaphragm thickening ratio was normal in the majority of patients, and intercostal muscles had higher GSA than diaphragm in relation to the controls.ConclusionUltrasound is useful for quantifying muscular changes in SMA and correlates with functional status. Diaphragm thickening ratio can be normal even with severe compromise of respiratory muscles in quantitative analysis, and intercostal muscles were more affected than diaphragm. 相似文献

BackgroundRecent studies presented that increased adiposity and hyperlipidemia may cause tendon pathology. The aim of this study was to evaluate the effect of hyperlipidemia on the patellar tendon stiffness by shear wave elastography.MethodsA total of 51 participants (19 female, 32 male) were included. Participants were divided into two groups, according to their low-density lipoprotein levels, as the study group (hyperlipidemia, n = 24) and the control group (non-hyperlipidemia, n = 27). The patellar tendon and rectus femoris muscle shear wave velocities were measured by shear wave elastography.FindingsPatellar tendon shear wave velocities was 5.02 (SD: 0.78) m/s in the control group and 5.98 (SD: 1.19) m/s in the hyperlipidemia group (ES = 0.95, P = .001). There was a positive moderate statistically significant correlation between patellar tendon shear wave velocity and low-density lipoprotein (r = 0.432, p < .002). In the multiple linear regression analysis, only low-density lipoprotein was found as a significant predictor of patellar tendon shear wave velocity (CI: 0.005–0.028, P = .007).InterpretationWe evaluated the effects of hyperlipidemia and body mass index on patellar tendon mechanical properties with shear wave elastography. We found that the blood low-density lipoprotein level had an impact on patellar tendon stiffness independently of body mass index. Accordingly, it is important to evaluate individuals' low-density lipoprotein levels when examining risk factors for tendon pathology. 相似文献

INTRA‐RATER AND INTER‐RATER RELIABILITY OF THE FIVE IMAGE‐BASED CRITERIA OF THE FOOT POSTURE INDEX‐6
Masafumi Terada Ara M. Wittwer Phillip A. Gribble 《International Journal of Sports Physical Therapy》2014,9(2):187-194
Purpose/Background:
The Foot Posture Index‐6 (FPI‐6) is considered a simple quantification tool to assess static foot alignment. Palpation of the foot is required for assessment of one of the six criteria that comprise the FPI‐6; the remaining five criteria may be evaluated using still‐frame photographs. Using only the image‐based criteria may allow multiple clinicians to evaluate large groups of patients quickly. Reliability using only these five image‐based criteria has not been established. The purposes of the current study were to establish the inter‐ and intra‐rater reliability using five image‐based criteria from the Foot Posture Index‐6 (FPI‐6) as well as to examine the agreement between the raters in identifying foot type using the composite five FPI scores.Methods:
Forty participants (23 females, 17 males; 23.67 ± 8.49 years; 64.59 ± 14.43 kg; 166.07 ± 11.79 cm) volunteered for this study. An investigator took three photos with a digital camera of the medial longitudinal arch, posterior ankle, and of the talonavicular joint approximately 45° from the posterior calcaneus for both right and left feet. Two investigators assessed the five image‐based criteria of the FPI‐6 for both feet of 40 participants on three occasions separated by a day. Inter‐and intra‐rater reliability were assessed with Intraclass Correlation Coefficients (ICC3,2). The amount of agreement for classification of foot posture type between the two raters was assessed with Cohen''s kappa coefficient. Significance was set a priori at P < 0.05.Results:
The inter‐rater reliability was poor to moderate for all three sessions (ICC3,2 = 0.334‐0.634). For the foot posture classification, the amount of agreement between two raters was poor for left (κ= 0.12) and right (κ= 0.19) feet. The intra‐rater reliability was excellent for left (ICC3,2=0.956) and right feet (ICC3,2=0.959).Conclusions:
Excellent intra‐rater and poor to moderate inter‐rater reliability was found using only the five image‐based criteria of the FPI‐6. However, the classification of foot posture did not improve the amount of agreement between raters. Therefore, caution is needed when interpreting FPI scores from five image‐based criteria.Levels of Evidence:

BackgroundDespite evidence of the impact of discharge teaching on patient outcomes, nursing students are poorly prepared in the pedagogical skills necessary for their role as patient and family educators in clinical practice. This study evaluated the effectiveness of simulation combined with online learning to improve nursing students’ discharge teaching skills.MethodsThe module included simulations before and after an online module on patient/family teaching for hospital discharge. Evaluation measures were student and independent rater evaluations using the Quality of Discharge Teaching Scale- Evaluation form (QDTS-E).ResultsStudents (n = 153) improved their performance on both content and delivery subscales of the QDTS-E by 20% (student self-evaluations) and 18% (independent raters). However, correlations between student and rater scores were low (r = 0.08-0.22).ConclusionUse of simulation with online learning in a discharge teaching module can help students build patient education skills to improve post-discharge patient outcomes, contributing to national health priorities to reduce hospital readmissions. With further refinement and testing, the learning module and QDTS-E evaluation form may also be useful for evaluation and continuing education of clinical nursing staff. 相似文献

BackgroundThis double-blinded randomized-controlled-trial aimed to identify the effects of an elastic band resistance training on walking kinetics and muscle activities in young adults with genu valgus.MethodsForty-two male young adults aged 22.5(2.7) years with genu valgus were randomly allocated to two experimental groups. The intervention group (n = 21) conducted a 14-weeks elastic band resistance training. The control group was passive during the intervention period and received the same treatment after the post-tests. Pre and post training, ground reaction forces and lower limb muscle activities were recorded during walking.FindingsResults revealed significant group-by-time interactions for peak medial ground reaction force and time-to-peak for posterior ground reaction force in favor of the intervention group (p < 0.012; d = 0.83–3.76). Resistance training with elastic bands resulted in significantly larger peak medial ground reaction force (p < 0.001; d = 1.45) and longer time-to-peak for posterior ground reaction force (p < 0.001; d = 1.85). Finding showed significant group-by-time interactions for peak positive free moment amplitudes in favor of the intervention group (p < 0.001; d = 1.18–2.02). Resistance training resulted in a lower peak positive free moment amplitude (p = 0.001; d = 1.46). With regards to muscle activities, the analysis revealed significant group-by-time interactions for rectus femoris and gluteus medius activities during the push-off phase in favor of the intervention group (p < 0.038; d = 0.68–0.89). Resistance training induced higher rectus femoris (p = 0.038; d = 0.84) and gluteus medius (p = 0.007; d = 0.54) activities.InterpretationThis study proved the effectiveness of resistance training using elastic bands on kinetics and muscle activities during walking in male adults with genu valgus disorder. Given that this training regime is low cost, effective, and easy-to-administer, we suggest that it should be implemented as a rehabilitative or preventive means for young adults with genu valgus. 相似文献

This study aimed to determine the reliability and the smallest real difference of the Ankle Lunge test in an ankle fracture patient population.In the post immobilisation stage of ankle fracture, ankle dorsiflexion is an important measure of progress and outcome. The Ankle Lunge test measures weight bearing dorsiflexion, resulting in negative scores (knee to wall distance) and positive scores (toe to wall distance), for which the latter has proven reliability in normal subjects only.A consecutive sample of ankle fracture patients with permission to commence weight bearing, were recruited to the study. Three measurements of the Ankle Lunge Test were performed each by two raters, one senior and one junior physiotherapist. These occurred prior to therapy sessions in the second week after plaster removal. A standardised testing station was utilised and allowed for both knee to wall distance and toe to wall distance measurement.Data was collected from 10 individuals with ankle fracture, with an average age of 36 years (SD 14.8). Seventy seven percent of observations were negative. Intra and inter-rater reliability yielded intra class correlations at or above 0.97, p < .001. There was a significant systematic bias towards improved scores during repeated measurement for one rater (p = .01). The smallest real difference was calculated as 13.8 mm.The Ankle Lunge test is a practical and reliable tool for measuring weightbearing dorsiflexion post ankle fracture. 相似文献
