Compared with conventional dynamic nonlinear equation systems, a hybrid double-deck dynamic nonlinear equation system (H3DNES) not only has multiple layers describing more different tasks in practice, but also has a hybrid nonlinear structure of solution and its derivative describing their nonlinear constraints. Its characteristics lead to the ability to describe more complicated problems involving multiple constraints, and strong nonlinear and dynamic features, such as robot manipulator tracking control. Besides, noises are inevitable in practice and thus strong robustness of models solving H3DNES is also necessary...

PURPOSE: Resistance training at longer muscle lengths induces greater muscle hypertrophy and different neuromuscular functional adaptations than training at shorter muscle lengths. However, the acute time course of recovery of neuromuscular characteristics following resistance exercise at shorter and longer muscle lengths in the quadriceps has never been described. METHODS: Eight healthy, young participants, (4M, 4F) were randomly assigned to perform 4 sets of 8 maximal isometric contractions at shorter (SL; 50o knee flexion) or longer muscle lengths (LL; 90o knee flexion) in a crossover fashion...

BACKGROUND: Patellofemoral arthroplasty (PFA) is a treatment option for isolated patellofemoral arthritis. Custom PFA is an innovative procedure utilizing patient-specific instrumentation. The purpose of this study is to evaluate short-term functional outcomes and complications of the custom PFA in treatment of isolated patellofemoral arthritis. METHODS: A retrospective study was conducted to analyze patients who received a PFA operation from a single surgeon. Inclusion criteria were surgical patients from 2012 to 2018 who underwent PFA using a custom prosthesis implant...

BACKGROUND: The severity and frequency of drought are expected to increase substantially in the coming century and dramatically reduce crop yields. Manipulation of rhizosphere microbiomes is an emerging strategy for mitigating drought stress in agroecosystems. However, little is known about the mechanisms underlying how drought-resistant plant recruitment of specific rhizosphere fungi enhances drought adaptation of drought-sensitive wheats. Here, we investigated microbial community assembly features and functional profiles of rhizosphere microbiomes related to drought-resistant and drought-sensitive wheats by amplicon and shotgun metagenome sequencing techniques...

BACKGROUND: In the squat movement, the use of constant resistance (CR) generates greater compression and shear forces close to 90° of knee flexion, increasing joint overload. However, when used variable resistance (VR) there is no consensus about the effect of knee joint load. The aim of this study was to compare knee torques using constant or variable resistance during the squat exercise. METHODS: Twenty-one healthy male subjects (mean age, 24 [SD, 3] years; height, 1...

INTRODUCTION: Piriformis muscle syndrome (PMS) is a condition that can lead to symptoms including gluteal pain, local tenderness, and limitation of hip joint motion in daily activities, and it may have a major impact on some daily functions such as gait. We proposed that dry needling (DN) can improve the gait of individuals with PMS. METHODS: Thirty-two individuals with PMS were assigned equally and randomly to the treatment group or the wait-list control group...

INTRODUCTION: Ankle fractures are one of the most common lower extremity fractures. After surgery, the ankle joint is often immobilized in a plantar flexion position, and there have been many reported cases of limited ankle joint range of motion. Therefore, the purpose of the present study was to investigate the effect of regular massage interventions on ankle joint range of motion after removal of fixation. METHODS: The massage group comprised 30 patients who had sustained an ankle fracture and had undergone surgical fixation, physical therapy, and massage between November 2020 and March 2022...

BACKGROUND: Joint hypermobility is a spectrum of symptoms associated with connective tissue disorders. The main feature is the increased range of joint mobility. Hypermobility is rarely recognised in clinical practice. The diagnosis is based on the evaluation of diagnostic tests, mainly the Beighton score. The divergence of research methods means that patients do not receive a proper diagnosis and treatment. METHODS: The study used the Beighton score and the Sachse scale...

Postoperative stiffness is a challenging problem in the setting of primary total knee arthroplasty. There remains a relatively high prevalence of patients suffering from this condition, and it can lead to unsatisfactory outcomes and need for revision surgery as well as a large financial burden on the health care system. There are a number of factors that predispose patients to developing arthrofibrosis, including patient-specific factors and intraoperative and postoperative considerations. Arthrofibrosis can be treated effectively in the early stages with manipulation under anesthesia with or without lysis of adhesions, however, those who fail to respond to these interventions may require revision surgery, which generally has poorer outcomes when performed for this indication...

Virginia K Henderson, Jean-Michel Brismée
Joint mobilizations are well-established and extensively researched treatment modality for adults. However, it remains largely unexplored in the pediatric population. Physical therapists hesitate to perform joint mobilization on children because of lack of knowledge, concern for the developing skeletal system, and the paucity of research on the topic. The aim of this article is to present a decision tool created for a continuing education course with the purpose to instruct pediatric therapists in the safe and effective use of joint mobilizations in children...

Xin Cao, Evangelos A Coutsias, Sara Pollock
In this paper, a stable and accurate algorithm to compute all solutions of the inverse kinematics problem of a 6 revolute manipulator chain is presented. A system of equations is constructed based on the fundamental closure conditions, leading to a closed algebraic system of 20 equations involving 16 quantities, composed of trigonometric functions of five among the six unknown joint angles. Two among these five are stably eliminated using singular value decomposition (SVD) avoiding the need to consider special cases...

Various functional modulations of the stretch reflex help to stabilize actions, but the computational mechanism behind its context-dependent tuning remains unclear. While many studies have demonstrated that motor contexts associated with the task goal cause functional modulation of the stretch reflex of upper limbs, it is not well understood how visual contexts independent of the task requirements affect the stretch reflex. To explore this issue, we conducted two experiments testing 20 healthy human participants (age range 20-45, average 31...

CONTEXT: Osteopathic treatments regulate the neurovegetative system through joint mobilizations and manipulations, and myofascial and craniosacral techniques. Despite the growing body of research, the precise impact of osteopathic medicine on the autonomic nervous system (ANS) is not yet fully elucidated. As to Kuchera's techniques, the stimulation of the sympathetic trunk and prevertebral ganglia contributed to harmonization of the sympathetic activity. However, potential relationships between the harmonization of the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) axis largely remain uncertain and warrant further exploration...
