Contraction intensity scale skin#

Overall, there were few sex-related differences in the fatigue responses during intermittent contractions. Biceps brachii EMG and elbow flexion torque steadiness were examined throughout each protocol, and motor nerve stimulation was used to quantify central and peripheral fatigue. Two contraction protocols were matched for intensity (20% MVC) and total contraction time (600-s). The purpose of this study was to examine fatigue responses in a cohort of healthy men ( nВ =В 7, age В =В 21.6В В±В 1.1В year) and women ( nВ =В 7, age: 22.0В В±В 2.0В year) during sustained isometric and intermittent isometric contractions. In particular, contractions that are held for long durations, rather than contractions that are interspersed with rest periods, may induce greater levels of fatigue in men compared to women. persons deprived of liberty by administrative or judicial decision or under legal guardianship.Sex differences in motor performance may arise depending on the mode of contraction being performed.persons with Implanted cardiac support systems (pacemaker, implanted defibrillator).

skin lesions, infections or strictures in the neck area.not able to read and understand the national language German.conditions that limit the mobility of the diaphragm (high intra-abdominal pressure, ascites, BMI >30).known neurological conditions with motor muscle weakness.chronic lung diseases (bronchial asthma, COPD).Written informed consent by the patient for participation in the study given.No relevant pre-existing conditions - corresponding to American Society of Anesthesiologists (ASA) level of I-II.Applicable for Group 2: planned for elective surgery.Healthy Subjects Elective Surgical Procedure The knowledge gained will be used to further develop the technique and to prepare a study in critically ill, ventilated patients where the diaphragmatic muscle is to be treated preventively by stimulating the phrenic nerve, in order to prevent atrophy of the muscle. Different stimulation protocols will be used.ДЇinally, it will be investigated whether an adjusted coil position still triggers reproducible diaphragmatic contractions after removal and repositioning in the same configuration. The possible occurrence of discomfort and pain sensation will also be investigated in awake healthy volunteers. Further, the characterization of the position finding process is of great importance, so that technical developments can further simplify the process of coil positioning in the future. This applies to inspiration and expiration detection for subsequent synchronization mechanisms of the magnetic stimulator for patient-initiated breathing as well as to contraction intensity. The scientific study is intended to show that external non-invasive electromagnetic stimulation can be used to safely and effectively stimulate the phrenic nerve in awake healthy subjects as well as in ventilated, anesthetized patients and that the stimulation can generate a diaphragmatic contraction that generates significant breath volume - a Controlled Own Breath (COB).ДЄlso of interest is the reproducibility of the generated diaphragmatic movements and the reliability of different feedback signals for detecting the generated diaphragmatic contraction.
