Gilberto Pires da Rosa, Francisca Costa, Joana Guimarães, Fernando Friões
We report the case of a 50-year-old caucasian man presenting with lumbar pain, bilateral ataxia, central facial palsy, ophthalmoparesis and urinary retention. Cerebral MRI hinted a hyperintensity of the medulla oblongata and cervical medulla suggestive of myelitis. Cerebrospinal fluid displayed lymphocytic pleocytosis and elevated protein concentration. Without the possibility to rule out an infectious or inflammatory aetiology, antibiotics and corticosteroids were started. Nevertheless, neurological status deteriorated with loss of muscle strength and left eye amaurosis...

A brief intervention using Zero-time Exercise (ZTEx), a foot-in-the-door approach, was developed to reduce sedentary behaviour and increase physical activity. ZTEx refers to the integration of simple strength- and stamina-enhancing physical activity into daily life, which can be done anytime, anywhere and by anyone. This paper presents the development, feasibility, and preliminary evidence for the effectiveness of this intervention under the Hong Kong Jockey Club FAMILY Project. Needs assessments were conducted with social workers from the Christian Family Services Center(CFSC) and the Social Welfare Department (SWD)...

One of the main priorities of rehabilitation after anterior cruciate ligament reconstruction (ACLR) surgery is the restoration of knee extensor muscle strength. Residual deficits in knee extensor muscle size and strength after injury are linked to poor biomechanics, reduced knee function, increased knee osteoarthritis risk, as well as heightened risk of re-injury upon return to sport. Most studies indicate that knee extensor muscle strength is typically not resolved prior to return to sport. This clinical commentary discusses strategies to optimize and accelerate the recovery of knee extensor strength post-surgery, with the purpose to support the clinician with evidence-based strategies to implement into clinical practice...

k-nearest neighbour (k-NN) has been shown to be an effective learning algorithm for classification and prediction. However, the application of k-NN for prediction and classification in specific sport is still in its infancy. The present study classified and predicted high and low potential archers from a set of physical fitness variables trained on a variation of k-NN algorithms and logistic regression. 50 youth archers with the mean age and standard deviation of (17.0 ± 0.56) years drawn from various archery programmes completed a one end archery shooting score test...

Severe lower limb spasticity can hinder motor tasks and negatively impacts the quality of life in patients with cerebral palsy. Selective dorsal rhizotomy is a well-established neurosurgical intervention aimed at reducing muscle spasticity in patients with such neuromuscular conditions. Long-term outcomes of selective dorsal rhizotomy have been promising among the authors' institutional series of patients. In this case, we demonstrate the use of L1-S1 osteoplastic laminoplasty and L1-S1 selective dorsal rhizotomy in a 5-year-old male patient with cerebral palsy and spastic lower extremity diplegia...

From 1980 to 2000, physical fitness decreased and body mass index (BMI) increased in the population of many industrialised countries. Little is known about these trends after the year 2000. The present study aimed to investigate physical fitness performance, physical activity (PA) behaviour and BMI of young, male Swiss adults between 2006 and 2015. For this purpose, results from the Swiss Armed Forces mandatory recruitment were used. 306,746 male conscripts provided complete fitness test data, mean±SD (range from 5th to 95th -percentile): 20±1 (18-21)yrs...

CONTEXT: Core control and strength are important for reducing the risk of lower extremity injury. Current evidence on the effect of core training in male adolescent athletes is limited, and other investigations into the effects of core training often emphasized core strength only. OBJECTIVE: To examine whether core training emphasizing both control and strength of the trunk and hip would improve joint kinematics during landing, sports performance, and lower extremity muscle strength in adolescent male volleyball athletes...

Muscle strength - the maximal force generating capacity of a muscle or group of muscles - is regularly assessed in physiological experiments and clinical trials. An understanding of the expected variation in strength and the factors that contribute to this variation is important when designing experiments, describing methodologies, interpreting results, and attempting to replicate methods of others and reproduce their findings. In this review (Cores of Reproducibility in Physiology), we report on the intra- and inter-rater reliability of tests of upper- and lower-limb muscle strength and voluntary activation in humans...

Proper alignment in dancers is a pre-requisite for achieving aesthetic line and form and for efficient execution of movement. Pelvic alignment is a common deficit in dancers that results in faulty technique and impaired performance. Dancers must be able to obtain their personal neutral alignment to avoid injury and achieve ease of execution. This study was designed to examine the effects, qualitatively and quantitatively, of Pilates training on pelvic alignment, strength, and flexibility in dancers. Twenty female dancers, 17 to 22 years of age, participated in a screening that consisted of an AlignaBod posture screen, upper abdominal manual muscle test, double leg lower test, straight leg raise test, and modified Thomas test...

Background and purpose - Improvement of physical function is one of the main treatment goals in severe hip osteoarthritis (OA) patients. The Osteoarthritis Research Society International (OARSI) has identified a core set of performance-based tests to assess the construct physical function: 30-s chair stand test (30-s CST), 4x10-meter fast-paced walk test (40 m FPWT), and a stair-climb test. Despite this recommendation, available evidence on the measurement properties is limited. We evaluated the reliability, validity, and responsiveness of these performance-based measures in patients with hip OA scheduled for total hip arthroplasty (THA)...

BACKGROUND: Overuse injuries (OI) are common in elite athletics. Previous studies have had athletes self-report injuries rather than having a medical professional provide a clear diagnosis. This might be a major reason for the inconsistencies in reported incident proportions of OI in elite athletics, in addition to the varying definitions of OI in current literature. Risk factors or combinations of risk factors (biomechanical, clinical, and training-related) have been shown to be important in the developmental process of OI...

Thermotherapy is a widespread technique that provides relief for muscle spasms and joint injuries. A great deal of energy is used to heat the surrounding environment, and heat emitted by the human body is wasted on our surroundings. Herein, a woven Kevlar fiber (WKF)-based personal thermal management device was fabricated by directly growing vertical copper-nickel (Cu-Ni) nanowires (NWs) on the WKF surface using a hydrothermal method. The treated WKF was combined with reduced graphene oxide (rGO) dispersed in polydimethylsiloxane (PDMS) to form composites using vacuum-assisted resin transfer molding (VARTM)...
