Batoul Sayed Ahmed, Marena Lamy, Debra Cameron, Lisa Artero, Sandra Ramdial, Matthew Leineweber, Jan Andrysek
BACKGROUND: Individuals with limb absence benefit from participating in sports. While barriers and facilitators affecting sport participation are well documented for adults, they have not been explored for children with limb absence. PURPOSE: To identify the perceived factors impacting participation in sports according to children with limb absence and their parents. METHODS: This study uses a descriptive qualitative study design. Nineteen participants, consisting of children and their parents, were recruited from an outpatient hospital clinic for semi-structured interviews...

BACKGROUND: It is known that some people can, and do, sustain >1 injury over a playing season. However, there is currently little high-quality epidemiological evidence about the risk of, and relationships between, multiple and subsequent injuries. PURPOSE: To describe the subsequent injuries sustained by Australian Football League (AFL) players over 1 season, including their most common injury diagnoses. STUDY DESIGN: Cohort study; Level of evidence, 3...

Philip von Rosen, Annette Heijne
Classifying subsequent injuries is of high importance in injury epidemiology since a previous injury has been reported to increase the risk of a new injury or increase the risk of a more severe injury. Multiple reports have shown that self-reported data provide an extensive view of an injury problem and add valuable information to the understanding of the athlete's health. The purpose of this study was to display a method that can be used to facilitate classification of subsequent injuries and to discuss challenges faced when categorising subsequent injuries based on self-reported data...

#4
Rezvan Kianifar, Alex Lee, Sachin Raina, Dana Kulic
Many assessment and diagnosis protocols in rehabilitation, orthopedic surgery and sports medicine rely on mobility tests like the Single Leg Squat (SLS). In this study, a set of three Inertial Measurement Units (IMUs) were used to estimate the joint pose during SLS and to classify the SLS as poor, moderate or good. An Extended Kalman Filter pose estimation method was used to estimate kinematic joint variables, and time domain features were generated based on these variables. The most important features were then selected and used to train Support Vector Machine (SVM), Linear Multinomial Logistic Regression, and Decision Tree classifiers...

In this paper, we focus on oxygen consumption (VO2) estimation using 6-axis motion sensor (3-axis accelerometer and 3-axis gyroscope) for people playing sports with diverse intensities. The VO2 estimated with a small motion sensor can be used to calculate the energy expenditure, however, its accuracy depends on the intensities of various types of activities. In order to achieve high accuracy over a wide range of intensities, we employ an estimation framework that first classifies activities with a simple machine-learning based classification algorithm...

REVIEW
Mark J Winston, Andrew J Weiland
Scaphoid fractures are a common wrist injury, especially in athletes. Clinicians should have a high index of suspicion for a scaphoid fracture in any patient complaining of radial-sided wrist pain after a fall on an outstretched hand. Advanced imaging, including CT and MRI scans, may be useful in diagnosis and classification of fracture patterns. Treatment varies based on the fracture location, stability of the fracture, and predictability of the fracture to heal. Treatment involves either non-operative management with a thumb spica cast or brace, or operative fixation with a headless compression screw, k-wires, or scaphoid-specific plates...

Pathological forms of exercising are a topic of debate in terms of classification, etiology, and treatment. Validated instruments are a precondition for research in this field. The aim of this study was to validate the German version of the Commitment to Exercise Scale (CES-de). A confirmatory factor analysis was conducted using data from a large community sample (n = 571). In a second study, 100 eating disordered patients, 107 elite athletes and 100 individuals engaged in leisure time sporting activities were compared to assess discriminant validity and psychological correlates...

Many Olympians and Paralympians would not be called athletes if what dictates this classification is fulfilling the criteria of Araujo and Scharhag (2016). Shelley Watts, Australian amateur boxer and Commonwealth gold medallist undertakes a double degree in law and sports science, something which undoubtedly takes up a considerable number of hours throughout her week (Australian Olympic Committie [AOC], 2016). There are many other athletes in similar positions - College athletes in the United States who are part of the National Collegiate Athletic Association (NCAA), for example...

BACKGROUND: Physical exercises are effective in the treatment of osteoarthritis (OA). There is consensus that exercise interventions should take into account the patient's preferences and needs in order to improve compliance to exercise regimes. One important personal factor is the patient's motivation for physical exercise. Health improvement is a relevant motive for exercise participation. Accordingly, exercise interventions primarily focus on health related needs such as strengthening and pain reduction...

The Topographic Attentive Mapping (TAM) network is a biologically-inspired classifier that bears similarities to the human visual system. In case of wrong classification during training, an attentional top-down signal modulates synaptic weights in intermediate layers to reduce the difference between the desired output and the classifier's output. When used in a TAM network, the proposed pruning algorithm improves classification accuracy and allows extracting knowledge as represented by the network structure...

David Whiteside, Olivia Cant, Molly Connolly, Machar Reid
PURPOSE: Quantifying external workload is fundamental to training prescription in sport. In tennis, global positioning data are imprecise and fail to capture hitting loads. The current gold standard (manual notation) is time intensive and often not possible given players' heavy travel schedules. The aim of this study was to develop an automated stroke classification system to help quantify hitting load in tennis. METHODS: 18 athletes wore an inertial measurement unit (IMU) on their wrist during 66 video-recorded training sessions...

We aimed to evaluate the influence of wheelchair rugby (WR) classification and competitive level on the seated limits of stability of athletes with disabilities. Twenty-eight athletes were recruited from international and national level WR teams. Athletes were distributed into three groups per their classification: low-point (0.5-1.5-point); mid-point (2.0-2.5-point); and high-point (3.0-3.5-point). Athletes were asked to sit on a force platform placed upon a wooden block and to lean the body as far as possible in eight pre-defined directions...

​In team sport, classifying playing position based on a players' expressed skill sets can provide a guide to talent identification by enabling the recognition of performance attributes relative to playing position. Here, elite junior Australian football players were a priori classified into 1 of 4 common playing positions; forward, midfield, defence, and ruck. Three analysis approaches were used to assess the extent to which 12 in-game skill performance indicators could classify playing position. These were a linear discriminant analysis (LDA), random forest, and a PART decision list...
