The Association of Genetic Markers Involved in Muscle Performance Responding to Lactate Levels during Physical Exercise Therapy by Nordic Walking in Patients with Long COVID Syndrome: A Nonrandomized Controlled Pilot Study.

Several genetic markers have shown associations with muscle performance and physical abilities, but the response to exercise therapy is still unknown. The aim of this study was to test the response of patients with long COVID through an aerobic physical therapy strategy by the Nordic walking program and how several genetic polymorphisms involved in muscle performance influence physical capabilities. Using a nonrandomized controlled pilot study, 29 patients who previously suffered from COVID-19 (long COVID = 13, COVID-19 = 16) performed a Nordic walking exercise therapy program for 12 sessions.

Effects of Aerobic Exercise Therapy through Nordic Walking Program in Lactate Concentrations, Fatigue and Quality-of-Life in Patients with Long-COVID Syndrome: A Non-Randomized Parallel Controlled Trial.

Background: Long-COVID syndrome comprises a variety of signs and symptoms that develop during or after infection with COVID-19 which may affect the physical capabilities. However, there is a lack of studies investigating the effects of Long-COVID syndrome in sport capabilities after suffering from COVID-19 infection. The purpose of the study was to evaluate and compare lactate concentration and quality of life (QoL) in patients with Long-COVID with those who have not developed non-Long-COVID during Nordic walking exercise therapy.

Predictive Factors and Gene Polymorphisms in Susceptibility to Long COVID-19 Syndrome.

Long COVID-19 syndrome is present in 5-10% of patients infected with SARS-CoV-2, and there is still little information on the predisposing factors that lead to its development. The purpose of the study was to evaluate the predictive factors in early symptoms, clinical features and the role of Angiotensin-Converting Enzyme-2 () c.513-1451G>A (rs2106806) and c.

Construct Validity and Test-Retest Reliability of a Free Mobile Application to Evaluate Aerobic Capacity and Endurance in Post-COVID-19 Syndrome Patients-A Pilot Study.

Introduction: Disability associated with the symptoms of post-COVID-19 syndrome is one of its main features and can have a considerable impact on care and rehabilitation units. This, linked to a decreased aerobic capacity and endurance in post-COVID-19 syndrome patients, increases interest in studying the potential of mobile applications to assess performance capacity. The purpose of this research was to study how a free mobile application assesses aerobic capacity and endurance and its relationship with aerobic capacity, test-retest reliability, and endurance evaluated by a conventional test, along with fatigue and health-related quality of life.

Limits of stability in patients with vascular (due to diabetes) and nonvascular unilateral transtibial amputation: a cross-sectional study.

The aim of the study was to investigate the differences in the stability limits between patients with vascular and nonvascular unilateral transtibial amputation (UTA) and patients without amputation. Eighteen patients with UTA who used a prosthesis were divided into two groups: vascular (n=9) and nonvascular (n=9). Twenty-four patients without amputation served as the control group.

Weight Symmetry and Latency Scores for Unexpected Surface Perturbations in Subjects With Traumatic and Vascular Unilateral Transtibial Amputation.

Background: Subjects with lower limb amputation develop new motor control strategies to preserve balance when they experience unexpected perturbations. Most studies performed thus far have not aimed to discuss the possible differences in postural control between subjects with vascular unilateral transtibial amputation (UTA) and subjects with traumatic UTA.

Objective: To analyze the automatic postural reaction in response to unexpected surface perturbations in a sample of subjects with traumatic and vascular UTA and to compare these observations with those for a group of healthy subjects.

Comparison of stability limits in men with traumatic transtibial amputation and a nonamputee control group.

Background: Currently, knowledge is lacking about whether subjects with traumatic unilateral transtibial amputation (UTA) have a compromised ability to voluntarily move their center of gravity (COG) to positions within the limits of stability.

Objective: To analyze the ability to voluntarily move the COG to positions within the limits of stability in a sample of subjects with traumatic UTA.

Design: Observational, case-control study.

Knee and hip internal moments and upper-body kinematics in the frontal plane in unilateral transtibial amputees.

Objective: The aim of this study was to quantify the motor adaptations in the frontal plane made by unilateral transtibial amputees (UTAs), with special regard to: (1) abduction/adduction moment at the hip and knee valgus moment in the frontal plane; (2) pelvic and thorax obliquity; and (3) stride length and gait speed.

Methods: 15 Males with unilateral transtibial amputation comprised the subject group and 15 non-disabled individuals served as control group. Gait analysis was performed using the VICON MOTION SYSTEM(®) (Oxford Metrics, Oxford, UK).

Cardiac rehabilitation programs and health-related quality of life. State of the art.

Cardiovascular disease is the main health problem in developed countries. Prevention is presented as the most effective and efficient primary care intervention, whereas cardiac rehabilitation programs are considered the most effective of secondary prevention interventions; however, these are underused. This literature review examines the effectiveness and the levels of evidence of cardiac rehabilitation programs, their components, their development and role in developed countries, applications in different fields of research and treatment, including their psychological aspects, and their application in heart failure as a paradigm of disease care under this type of intervention.

Performance of the craniocervical flexion test, forward head posture, and headache clinical parameters in patients with chronic tension-type headache: a pilot study.

Design: Case-control, descriptive pilot study.

Objective: To describe the differences in the performance of the craniocervical flexion test (CCFT) between individuals with chronic tension-type headache (CTTH) and healthy controls. To assess the relationship between the CCFT, forward head posture, and several clinical variables related to the intensity and temporal profile of headache.
