KINETIC CHAIN MODIFIES MUSCLE ACTIVATION IN ADULTS WITH SHOULDER PAIN: A RANDOMIZED CROSS-OVER TRIAL.

Background: A kinetic chain approach to shoulder rehabilitation is recommended. This study aimed to compare muscle activity between the isolated external rotation exercise and an exercise incorporating a kinetic chain approach in adults with shoulder pain. It also sought to identify muscle activation differences with the same tasks between asymptomatic adults and those experiencing shoulder pain.

Mixing transcutaneous vagal nerve stimulation and galvanic cutaneous stimulation to decrease simulator adaptation syndrome.

Purpose: Simulator Adaptation Syndrome arises from a perceptual discordance between expected and actual motion, giving rise to symptoms such as nausea and disorientation. This research focused on determining the benefit of Transcutaneous Vagal Nerve Stimulation (tVNS) and Galvanic Cutaneous Stimulation (GCS), where both were applied in conjunction, as compared to their administration in isolation, to decrease Simulator Adaptation Syndrome (SAS).

Method: A driving simulation study was proposed where SAS, body balance, and driving performance were measured.

Effects of a pulmonary rehabilitation program on pulmonary function, exercise performance, and quality of life in patients with severe COVID-19.

Background: Severe coronavirus 2019 disease (COVID-19) causes acute hypoxemic respiratory failure requiring invasive mechanical ventilation (IMV). Once these symptoms are resolved, patients can present systemic deterioration.

Objective: The two objectives of this study were as follows: to describe the results of a pulmonary rehabilitation program (PRP), which is divided into three groups with different numbers of sessions (12, 24, and 36), and to associate the variables of pulmonary function, exercise performance, and functionality with the number of sessions and functional improvement.

[Quality of life, level of physical activity and functional tests in actively working adults and older people].

Background: The population of actively working older people is growing rapidly. The relationship between quality of life, levels of physical activity and functionality in this population is not entirely clear.

Aim: To determine the association between quality of life, levels of physical activity and functional tests in actively working adults and older people.

Pain and Psychological Readiness to Return to Sport in Elite Volleyball Players: A Cross-Sectional Study.

Unlabelled: Pain is modulated by multiple factors. A relevant psychological process peculiar to athletes and which could be associated with pain is Psychological Readiness to Return to Sport (PRRS). The analysis of this association in competition context is particularly important.

Transcutaneous Vagal Stimulation in Knee Osteoarthritis (TRAVKO): Protocol of a Superiority, Outcome Assessor- and Participant-Blind, Randomised Controlled Trial.

Current treatments for knee osteoarthritis (KOA) are partially effective. It is, therefore, necessary to find new strategies that can complement the existing ones. In this scenario, transcutaneous vagal stimulation (TVS) neurophysiological effects could be a helpful solution.

The Effect of Sleep Quality on Pain in Chilean Individuals with Musculoskeletal Disorders.

Unlabelled: Poor sleep quality (SQ) negatively affects pain associated with musculoskeletal disorders (MSD). As the level of economic development of a country determines its sanitary conditions, these can influence the sleep-pain relationship; therefore, it is relevant to generate evidence in the population with MSD in developing countries. This cross-sectional study sought to determine the effect of poor SQ on pain in Chilean individuals with MSD, controlling for sex and duration of pain (in months).

Frequency of Injury and Illness in the Final 4 Weeks before a Trail Running Competition.

We aimed to (i) determine self-reported injury and illness frequency in trail runners 4 weeks preceding competition; (ii) compare athletes with and without injury/illness by sex, age, body mass index (BMI) and competition distance; (iii) describe mechanism of injury, anatomical region (injury)/organ system (illness) involved, consequences of injury on preparation and self-perception of injury severity; (iv) compare anatomical region (injury) and organ system (illness) by sex. A total of 654 trail runners (age 36.2, IQR 30.

Influence of age on functional capacity and work ability in Chilean workers: a cross-sectional study.

Objective: To determine if there are differences in functional capacity and work ability between older and younger active workers in public institutions, and to relate functional capacity to work ability.

Methods: This cross-sectional study evaluated 360 subjects from two public institutions, a university and a high-complexity regional hospital. The participants were divided into 3 age ranges 40-49, 50-59 and ≥ 60 years.

The association of musculoskeletal complaints and individual and work-related factors with work ability in Chilean white-collar and blue-collar workers.

The maintenance of good work ability has proven to have a positive effect on health, quality of work and productivity. There is little evidence regarding the association between musculoskeletal complaints, individual and work-related factors, and work ability in blue-collar and white-collar workers. .

Joint and individual effectiveness of galvanic cutaneous stimulation and tactile stimulation at decreasing Simulator Adaptation Syndrome.

This research was focused on investigating the effectiveness of galvanic cutaneous stimulation and tactile stimulation jointly and individually at mitigating Simulator Adaptation Syndrome. Forty drivers (mean age = 23.1 ± 3.

Muscle activation in semantic processing: An electromyography approach.

In this study, we focus on the spontaneous activity related to manual verbs to determine the extent to which semantic processing of manual verbs affects spontaneous arm muscle activity. For this purpose, we recorded the arm's electromyographic activity while participants read manual and non-manual verbs, focusing their attention on the semantic content or a specific letter. In addition, we manipulated the arm position (in front of the body or behind the back) to observe postural priming effects for spontaneous muscle activity.

Psychometric Properties of the Spanish Version of the Work Ability Index in Working Individuals.

It is increasingly important to have validated instruments to assess the ability to work. Thus, the aim of this study was to evaluate the psychometric properties of the Spanish version of the Work Ability Index (WAI) in working individuals. A cross-sectional study was conducted on 360 workers (men and women) in a high-complexity public hospital and in a public university.

Psychometric properties of the Spanish version of the Edinburgh Handedness Inventory in a sample of Chilean undergraduates.

An individual's nervous and cognitive systems are lateralized, and handedness represents a behavioral manifestation of such organization. Therefore, accurately and reliably measuring handedness has repercussion on our understanding of both the human brain and cognition. The Edinburgh Handedness Inventory (EHI) is the most frequently used instrument to measure handedness both in clinical practice and research.

Decreasing motion sickness by mixing different techniques.

We investigated the effectiveness of galvanic cutaneous stimulation (GCS) and auditory stimulation (AS) together and separately in mitigating motion sickness (MS). Forty-eight drivers (twenty-two men; mean age = 21.58 years) participated in a driving simulation experiment.

Pain and Distraction According to Sensory Modalities: Current Findings and Future Directions.

Background: This review discusses the findings in the literature on pain and distraction tasks according to their sensory modality. Distraction tasks have been shown to reduce (experimentally induced) acute pain and chronic pain. This can be influenced by nature and by the sensory modalities used in the distraction tasks.

Response Inhibition as a Function of Movement Complexity and Movement Type Selection.

This study aims to determine whether response inhibition shows the same degree of effectiveness for two sources of motor complexity: (1) Movement complexity, which is measured through two actions with different motor requirements (simple lifting action vs. complex reaching action), and (2) Movement type selection, which is measured in movements performed separately (no active-movement type selection) vs. selectively (active-movement type selection).
