Objective: Six months after the onset of stroke, over 60% of patients experience upper limb dysfunction, with spasticity being a major contributor alongside muscle weakness. This study investigated the effect of transcutaneous electrical nerve stimulation (TENS) with taping on wrist spasticity, strength, and upper extremity function in patients with stroke. Methods: In total, 40 patients with stroke were included and randomly divided into two groups: the TENS + taping ( n = 20, age 52.4 ± 9.3 (range: 39 to 70)) and TENS ( n = 20, age 53...

BACKGROUND: Cerebral palsy (CP) is one of the primary causes of physical disabilities in children that affects posture and movement. Upper-extremity (UE) function is frequently impaired, which may result in activity and participation limitations in people with CP. The use of kinesiotape (KT) has increased in the treatment of CP for various purposes. The aim of this systematic review was to assess the efficacy of KT for improving UE function in children and adolescents with CP. METHODS: The literature search was carried out in PubMed, Cochrane, PEDro, Web of Science and SCOPUS databases...

OBJECTIVE: We aimed to determine the anthropometric measurements and ergonomic risk levels of students during a handwriting activity on a fixed desk and chair and to analyze the mismatch and relationships between these factors. METHODS: This study included 149 university students (female:73, male:76)...

Studies of vertebrate bone biomechanics often focus on skeletal adaptations at upper extremes of body mass, disregarding the importance of skeletal adaptations at lower extremes. Yet mammals are ancestrally small and most modern species have masses under 5 kg, so the evolution of morphology and function at small size should be prioritized for understanding how mammals subsist. We examined allometric scaling of lumbar vertebrae in the small-bodied Philippine endemic rodents known as cloud rats, which vary in mass across two orders of magnitude (15...

BACKGROUND: Previous research has shown that noninvasive brain stimulation can be used to study how the central nervous system (CNS) prepares the execution of a motor task. However, these previous studies have been limited to a single muscle or single degree of freedom movements (e.g., wrist flexion). It is currently unclear if the findings of these studies generalize to multi-joint movements involving multiple muscles, which may be influenced by kinematic redundancy and muscle synergies...

BACKGROUND/PURPOSE: No studies have observed the effects of a collegiate lacrosse season on movement pattern quality, dynamic postural control, or the accuracy of athletes' perceived movement pattern quality. The purpose was to examine the effects of a nontraditional fall season on movement pattern quality, perceived movement pattern quality, and dynamic postural control in collegiate lacrosse athletes. DESIGN: Cross-sectional laboratory study. METHODS: Fifty men's (age=19...

INTRODUCTION: Lower Cross Syndrome (LCS) is a prevalent condition that manifests as muscular tension due to the asymmetry in the strength of the lower extremity muscles. This imbalance could be due to the tautness of the iliopsoas, rectus femoris, tensor fascia latae, adductor group, gastrocnemius, and soleus muscles. LCS causes a postural imbalance in the individual, which triggers low back pain (LBP). When LCS is present alongside LBP, may cause the upper body to sway more in the transverse plane and at the lumbar level, making walking and termination of gait (GT) more difficult...

Archery ranks among the sports with a high incidence of upper extremity injuries, particularly affecting the drawing shoulder and elbow, as well as inducing stress on the lower back. This study seeks to bridge the gap by integrating real-time human motion with biomechanical software to enhance the ergonomics of archers. Thirteen participants were involved in four tasks, using different bows with varied draw weights and shooting distances. Through the application of advanced integrative technology, this study highlights the distinct postures adopted by both males and females, which indicate the biomechanical differences between genders...

Background: Forward head posture and rounded shoulder posture are common postural variants found in upper crossed syndrome, which can lead to limited neck mobility, respiratory problems, and other issues. The purpose of this study was to investigate the effects of telerehabilitation, combining diaphragmatic breathing re-education and shoulder stabilization exercises, on young men with upper crossed syndrome during the COVID-19 pandemic over 4 weeks. Methods: The study included 37 participants aged in their 20s and 30s who were randomly divided into two groups...

Objectives . Shoulder protraction is frequently seen in office workers because of working with excessive trunk flexion for a long time. This study aimed to compare the effectiveness of stabilization exercises (SE) given in addition to office exercises (OE). Methods . Sixty office workers with shoulder protraction were divided into SE + OE ( n =  30) and OE ( n =  30) groups by stratified random sampling for 8 weeks and followed up for 4 weeks. Shoulder protraction was assessed with a caliper, muscle strength with a hand-held dynamometer, proprioception with an isokinetic dynamometer, vibration sense with a vibrometer and upper extremity functional performance with the closed kinetic chain upper extremity stability test...

The shift from film to PACS in reading rooms, coupled with escalating case volumes, exposes radiologists to the issues of the modern computer workstation including computer work posture and work-related musculoskeletal disorders (WMSD). Common WMSDs affecting the neck and upper extremities include cervical myofascial pain, shoulder tendonitis, lateral epicondylitis, carpal tunnel syndrome, and cubital tunnel syndrome. This review examines each pathology along with its pathogenesis, clinical features, physical exam findings, and potential risk factors...

BACKGROUND: Asymmetry in involuntary trunk motion during voluntary movements of the lower extremities is a risk factor for musculoskeletal injuries and may be related to core stability. Core stability plays a pivotal role in maintaining postural stability during distal segment movements. Because mediolateral head motion partially represents trunk motion during rhythmic movements, controlling it can help ensure symmetric trunk motion. This study aimed to investigate the relationship between core stability and asymmetric trunk motion during rhythmic movements, and to evaluate the effects of feedback music on mediolateral head motion...

BACKGROUND: Poor balance ability may contribute to shoulder pathology in patients with existing shoulder pathologies or vice versa. The relationship between kinesiophobia and chronic shoulder pain intensity has been researched, although the conclusions are conflicting. To our knowledge, no study in the literature explores the association between kinesiophobia and balance in patients with shoulder pain. OBJECTIVE: To investigate the relationship between kinesiophobia, upper extremity functions, and balance abilities in patients with shoulder pain...

A 67-year-old woman complained of rest and postural tremors in her left upper extremity, associated with bradykinesia and gait disorder since 2 years ago, with no significant response to antiparkinsonism drugs. Dopamine transporter SPECT/CT revealed a remarkable area of 99mTc-TRODAT-1 uptake in a huge tumoral lesion in the right frontotemporal region, compressing and dislocating the right striatum with evidence of significant midline shift. The patient underwent surgical resection with a diagnosis of meningioma on preoperative MRI and postoperative histology report, experiencing a marked recovery in symptoms after 1 month...

BACKGROUND: Gait and cognition are closely associated in Parkinson's disease (PD), with specific cognitive domains being associated with different motor symptoms.
