Masticatory and Neck Muscles' Isometric Endurance and Their Relation to Upper Limb Isometric Grip Strength in Sport Climbers-Preliminary Investigation.

: Sport climbing's popularity has grown with its inclusion in the Olympics and increased accessibility. Understanding the relationship between hand dominance, grip strength, endurance, and the involvement of masticatory and neck muscles can provide valuable insights into the neuromuscular adaptations specific to sport climbing, potentially aiding performance optimization and injury prevention in intermediate and advanced climbers. This study analyzes if the dominant hand has greater isometric endurance and isometric manual grip strength parameters than the non-dominant one and examines its relation to the masticatory and neck muscles in intermediate and advanced sport climbers.

The impact of various subtypes of temporomandibular disorders on body balance - preliminary study.

Background: Balance disorders are considered a serious diagnostic challenge, with many potential causes. The influence of temporomandibular disorders (TMD) on postural balance has numerous anatomical, biomechanical, physiological and functional argumentation, however, cohort studies on this subject do not give unambiguous results. It is suggested that only some forms of TMD may affect the body balance.

Tendon Cell Biology: Effect of Mechanical Loading.

Tendons play a crucial role in the musculoskeletal system, connecting muscles to bones and enabling efficient force transfer. However, they are prone to acute and chronic injuries, which, if not properly repaired, can significantly impair function. Tendinopathy, a prevalent condition affecting approximately 20% of musculoskeletal complaints, arises from an imbalance between micro-injury accumulation and repair processes.

Evaluation of the effectiveness of selected physiotherapeutic techniques at trigger point in myalgia form of temporomandibular disorders - randomized controlled trial.

Objectives: The main aim of this study was to evaluate bioelectrical activity the immediate effect of the post-isometric relaxation technique (PIR) and compression technique in patients with myalgia of the masticatory muscles.

Materials And Methods: 97 people were divided into 3 groups: the first group underwent PIR, the second group underwent trigger point compression technique, and the third group consisted of individuals without myalgia of the masticatory muscles, serving as the control group and not experiencing any therapeutic intervention.

Results: After the therapy, a decrease in the bioelectrical activity of the masticatory muscles and an improvement in jaw mobility were observed.

Ultrasound Imaging in Diagnosis and Management of Lower Limb Injuries: A Comprehensive Review.

Medical imaging tests are widely used to diagnose a broad spectrum of lower-limb injuries. Among these modalities, ultrasound (US) imaging has gained significant traction as a valuable diagnostic instrument for assessing conditions primarily affecting muscles, tendons, ligaments, and other soft tissues. However, there are important dilemmas related to the indications and possibilities of US in lower-limb injuries.

Evaluation of the bioelectrical activity of the masticatory muscles in patients with narrowed maxillary transverse dimension compared to the occlusal norm.

Objective: The aim of the study was to determine how the electrical activity of the temporalis, masseter and sternocleidomastoid muscles differs in children with reduced transverse jaw dimension compared to children with normal occlusion.

Design: It was a experimental study. Thirty-seven patients were included in the study.

Analysis of the Use of Sample Size and Effect Size Calculations in a Temporomandibular Disorders Randomised Controlled Trial-Short Narrative Review.

Background/objectives: Temporomandibular disorder (TMD) is the term used to describe a pathology (dysfunction and pain) in the masticatory muscles and temporomandibular joint (TMJ). There is an apparent upward trend in the publication of dental research and a need to continually improve the quality of research. Therefore, this study was conducted to analyse the use of sample size and effect size calculations in a TMD randomised controlled trial.

Pharmacologically Induced Accommodation Palsy and the Bioelectrical Activity of the Muscular System: A Preliminary Investigation.

The aim of this study was to pharmacologically induce accommodative paralysis and evaluate its effects on the bioelectrical activity of the muscular system. The study included two participant groups: those with myopia and those with normal vision (emmetropes). Electromyographic assessments were performed using the Noraxon Ultium DTS 8-K MR 3 myo Muscle Master Edition system.

Surface Electromyography in Dentistry-Past, Present and Future.

Surface electromyography (sEMG) is a technique for measuring and analyzing the electrical signals of muscle activity using electrodes placed on the skin's surface. The aim of this paper was to outline the history of the development and use of surface electromyography in dentistry, to show where research and technical solutions relating to surface electromyography currently lie, and to make recommendations for further research. sEMG is a diagnostic technique that has found significant application in dentistry.

Neck pain, disability and mobile phone usage among physiotherapy students - a cross-sectional study.

Introduction And Objective: Modern mobile devices have become tools used for educational, research, business or recreational purposes. Incorrect position during excessive use of a smartphone can lead to biomechanical changes, the most visible of which is the position of the head in protraction, characterized by the protrusion of the head and neck forward in relation to the shoulder girdle and trunk. The aim of the study was to analyze the relationship between disability, neck pain (NP), use of phones before bedtime, and hours of using smartphones.

Association between pain intensity, neck disability index, and working conditions among women employed in horticulture.

Introduction And Objective: One of the most frequent musculoskeletal disorders is neck pain (NP). NP can be associated with occupational activities and is more common among females than males. Horticulture is a branch of agriculture in which work is intensively manual, and characterized by repetitive tasks.

Study protocol: Accommodative effects on the musculoskeletal system.

Accommodation is a phenomenon of the eyeball, which consists of adapting to view objects at different distances. The main aim of this study is to evaluate the effect of accommodations on the musculoskeletal system in myopic and emmetropic subjects. To date, the effect of accommodative paralysis on the musculoskeletal system has not been studied.

Exploratory Study on Central Sensitization and Bioelectrical Activity of the Selected Masticatory Muscles in Subjects with Myopia.

Background: Myopia is one of the most common eye disorders involving abnormal focusing of light rays. The studies recognize the association between the stomatognathic and visual systems. This compound may have a neurological basis associated with disorders such as central sensitization.

Relationship of lumbar-hip kinematics during trunk flexion and sex, body mass index, and self-reported energy expenditure: a cross-sectional analysis.

Purpose: Physical activity (PA) is a well-known, simple and effective preventive and therapeutic intervention for low back pain (LBP). In spite of the growing interest in active lifestyles and its benefits, more needs to be known about the relationship between energy expenditure, body mass and lumbar-pelvic kinematics during the forward bending movement in a group of young asymptomatic people who met PA guidelines. Young people can be identified as a future risk group of civilisation diseases and lumbar-hip kinematics can be considered as a predictor of LBP occurrence.
