Kinetic Chain Rehabilitation in a Juvenile Idiopathic Arthritis Patient
CASE HISTORY: The patientâs chief complaint was decreasing ROM and pain noticed after conservative orthopedic treatment in the dominant (left) elbow. After extensive evaluation, the patient was diagnosed with juvenile idiopathic arthritis (JIA) at 9 years old. PHYSICAL EXAM: Upon physical therapist examination, it was determined that she had deficits throughout the entire left upper extremity and quadrant. Findings include signs and symptoms of Upper Cross Syndrome including pectoralis muscle group tightness, weakness of deep neck flexors with overuse of sternocleidomastoid and scalenes group, weakness of posterior shoulder and upper back including lower trap, middle trap, and all scapular stabilizing musculature including significant overuse of the upper trapezius and levator scapula complex. This presented as poor scapulothoracic rhythm and scapular dyskinesis with significant scapular winging, forward head and rounded shoulders causing inefficient mechanical function during functional movement patterns. Other specific objective findings included pectoralis minor length difference of right to left of one inch, MMT grade of teres minor and latissimus 3+/5, serratus anterior 3+/5, other rotator cuff reveals 4/5, with subscapularis 4/5. The initial AROM of the elbow revealed a 40° extension lag, excessive supination of 105° with limited pronation of 70°. DIFFERENTIAL DIAGNOSES: Medial epicondylitis, avulsion fracture, rheumatoid arthritis, ankylosing spondylitis. TESTS & RESULTS: X-rays and MRIs were obtained in order to make the JIA diagnosis. Imaging obtained by the patientâs rheumatologist nine months ago showed a slowing of the disease processes, confirmation of the cessation was confirmed on MRI obtained 3 months ago. After failing occupational therapy for ROM and joint sparing techniques, she was referred to physical therapy (PT) to address kinetic chain dysfunction to avoid other joint involvement. FINAL DIAGNOSIS: The final diagnosis was JIA with multiple joint involvement. For the purpose of this case study, Upper Cross Syndrome with associated scapular dyskinesis was addressed in rehabilitation. DISCUSSION: Treatment of JIA is often targeted at the involved joints. It is important for the medical professional to evaluate and address joints that are not currently involved in the disease process. In this case, the patientâs parents advocated for physical therapy. Many cases will go untreated which could affect the long-term functioning of the kinetic chain. Additionally, early intervention can improve functioning of other joints and increase strength of muscles that, when functioning at full capacity, could affect the involved joint. OUTCOME OF THE CASE: After 2 months of PT, objective findings revealed great improvements in pectoralis minor flexibility as demonstrated through measurement of just ½ inch which is symmetrical to the right side; increased postural awareness of downward scapular retraction; appropriate chin tuck posture due to increased deep neck flexor strength; decreased compensation of scalenes and upper trap and levator complex; improved rotator cuff strength and AROM pronation 82°. Most important, she is demonstrating improved awareness of correct downward retracted scapular position with little winging and good head alignment utilizing a chin tuck position. All AROM of the elbow remained the same. RETURN TO ACTIVITY AND FURTHER FOLLOW-UP: The patient is navigating all activities of daily living for her age group with a lack in ROM of her elbow. She competes on a shotgun team and plays sports at recess. She will continue with PT once per week for the next 3 months. After revaluation, she may be released with a maintenance program
Monitoring and Damping UMP Due Eccentricity Fault in Induction Machines: A Review
Š 2016 IEEE. Three-phase induction machines are reliable and widely used in industrial plants. The efficient condition monitoring can diagnose the inception of fault mechanisms in induction motors thus avoiding failure and expensive repairs. Therefore, there is a strong need to develop a more efficient condition monitoring. The main target is to achieve a relatively low cost and/or non-invasive system which is still powerful in terms of monitoring for online detection of developing faults. This digest adresses rotor eccentricity faults and study of conventional monitoring techniques for induction motor faults. In order to reduce the UMP in case of an eccentric rotor, the eccentricity-generated additional airgap flux waves should be reduced. Additional, the characteristics of UMP in induction machines are addressed. Methods to reduce the side-band flux waves and hence attenuate the UMP will be addressed
Graphics Processing Unit Accelerated Lattice Boltzmann Method Simulations of Dilute Gravity Currents
Lattice Boltzmann method models offer a novel framework for the simulation of
high Reynolds number dilute gravity currents. The numerical algorithm is well
suited to acceleration via implementation on massively parallel computer
architectures. Here we present two lattice Boltzmann method models of
lock-exchange dilute gravity currents, in which the largest turbulent length
scales are directly resolved. The three-dimensional simulations are accelerated
by exporting computations to a graphics processing unit and are validated
against experiments and high-resolution simulations for Reynolds numbers up to
30,000. The lattice Boltzmann method models achieve equivalent accuracy to
conventional large eddy simulation models in the prediction of key flow
properties. A conservative analysis of computational performance relative to
conventional methods indicates that the presented framework reduces simulation
times by two orders of magnitude. Therefore, it can be used as a foundation for
the development of depth-resolving models that capture more of the complexity
of environmental gravity currents.Comment: 59 pages, 14 figure
Functional Movement Screen Detected Asymmetry & Normative Values Among College-Aged Students
# Background
The Functional Movement Screen (FMSâ˘) is a popular test used by sports medicine professionals to identify dysfunctional movement patterns by analyzing mobility and stability during prescribed movements. Although the FMS⢠has been a popular topic of research in recent years, normative data and asymmetries in college-aged students have not been established through research.
# Purpose
The objective was to determine normative FMS⢠scores, report frequency counts for FMS⢠asymmetries, and determine if the number of sports seasons and number of different sports an individual participated in during high school varied between university students that showed FMS⢠identified asymmetries.
# Study Design
Cross-sectional Study
# Methods
One hundred university students completed the FMS⢠and an associated survey to determine which sport(s) and for how many seasons they participated in each sport(s) during high school. Total FMS⢠scores were assessed as well as identifying the presence of an asymmetry during a FMS⢠screen. An asymmetry within the FMS⢠was defined as achieving an unequal score on any of the screens that assessed right versus left movements of the body.
# Data Analysis
Data analysis included descriptive statistics, Pearson correlation was utilized to investigate the relationship between number of sports played and number of sport seasons. Shapiro Wilk test for normality, and Mann Whitney U test was employed to investigate group differences in number of sports played. All analyses were conducted using SPSS software.
# Results
Statistically significant correlations (r = .286, r^2^ = .08, p < 0.01) were found for both number of sport seasons and number of sports with FMS⢠total score. In addition, participants without FMSâ˘-detected asymmetries played significantly more seasons and more sports than their peers that presented asymmetries (U = 946.5, z = -1.98, p = 0.047). Finish with the actual p-value in parenthesis.
# Conclusion
Participating in multiple sports and multiple sport seasons during high school was associated with higher FMS⢠total scores. Results suggest that participating in multiple sports and multiple sport seasons was associated with fewer asymmetries, which may decrease subsequent injury risk.

Neuromuscular training improves movement competency and physical performance measures in 11-13 year old female netball athletes
The purpose of this study was to examine the effects of a neuromuscular training program on movement competency and measures of physical performance in youth female netball players. It was hypothesized that significant improvements would be found in movement competency and physical performance measures following the intervention. Twenty-three junior female netball players (age, 12.17 ¹ 0.94 yrs; height, 1.63 ¹ 0.08 m; weight, 51.81 ¹ 8.45 kg) completed a test battery before and after a six-week training intervention. 13 of these athletes underwent six weeks of neuromuscular training, which incorporated plyometrics and resistance training. Trained athletes showed significant improvements in 20 m sprint time, 505 agility time, countermovement jump height and peak power (p ⤠0.05, g \u3e 0.8). Additionally, trained athletes significantly improved their score in the Netball Movement Screening Tool (NMST) (p \u3c 0.05, g \u3e -1.30); while the athletes also demonstrated increased reach in the anterior and posteromedial directions for the right and left leg, and in the posterolateral direction for the left leg only in the Star Excursion Balance Test (SEBT) (p \u3c 0.05, g \u3e -0.03). Control subjects did not exhibit any significant changes during the 6-week period. Significant negative correlations were found between improved score on the NMST and decreased 5 m, 10 m and 20 m sprint time, and 505 change of direction time (r \u3e 0.4, p ⤠0.05). Results of the study affirm the hypothesis that a six-week neuromuscular training intervention can improve performance and movement competency in youth netball player

From Winckelmann to Wilde : masculinity and the historical poetics of nineteenth-century British Hellenism
This dissertation is a survey of nineteenth-century British Hellenism in texts authored between 1768 and 1895 by elite, bourgeois, and working-class people both female and male. Beginning in 18th-century Germany, the dissertation tracks the influence of Johann Joachim Winckelmann on nineteenth-century British Hellenism, asserting that there is a characteristic cluster of representational attributes visible in British Hellenist texts that display a shared ideological emphasis. Winckelmann, who rose from humble beginnings to become the Vaticanâs prefect of antiquities, bequeathed a systematic art-historical approach to classical Greek art that became an idealist discourse of British Greekness through the influence of the annual lectures given by Sir Joshua Reynolds, founding president of the Royal Academy of Art, to students between 1768 and 1792. Posthumously the âGrand Styleâ aesthetics Reynolds promulgated became highly politicized, its influence clear in the debates surrounding the parliamentary purchase of the Parthenon Marbles from Lord Elgin in 1816, in the poetry, prose, art and architecture of the 1820s and 1830s, in specific exhibits at the Great Exhibition of 1851, in the anthropological debates touched off by Darwinâs Origins of Species after 1859, and in Oscar Wildeâs fin-de-siĂŠcle advocacy of Dress Reform and his reformed, Reynoldsian aesthetic idealism. Particularly during Oscar Wildeâs 1895 trials, the political valence of nineteenth-century British Hellenism is inescapable, being explicitly enunciated in Wildeâs famous âThe Love That Dare Not Speak Its Nameâ speech, but I argue throughout that nineteenth-century British Hellenism tends to create âenfigurationsâ of subjectivity that constrain those who adopt them through insistent reference to an ideal subjectivity that is embodied in white, abled, elite, heterosexual male bodies resembling those found in classical Greek art. Thus I show that while the political valence of nineteenth-century British Hellenism could be contested, the terms of the debate remained fixed around an unmarked yet hypervisible central term, which fixity acted to foreclose radical political change throughout the nineteenth century, and particularly in the 1890s, when British sexological debates made the figure of the modern male homosexual visible at the same time that campaigns for tolerance of homosexuality were energetically quashedEnglis
Wave power resource dynamics for the period 1980-2021 in Atlantic Europe's Northwest seas
This paper explores the variability of wave power in space and time using a 42-year high-resolution hindcast wave model from the Copernicus Marine Environment Monitoring Service for the North-West European shelf. We calculate the wave energy flux using significant wave height and wave energy period. To improve wave power assessment, we use knowledge about mean wavelengths and bathymetry, which is necessary given the nature of the intermediate and shallow waters in the region. The results provide monthly, seasonal, and inter-annual estimates of wave power variability based on 122,728 modeled wave measurements. The study advances the understanding of wave energy resources within the domain
