The patient's dominant hand will be tested, with the patient as seated as possible, with the elbow as close as to 90º. Three measurements will be taken, respecting a minute interval between them, whose average of the three measurements will be collected.\n\nMuscle weakness will be diagnosed based on previously published weakness scores (for males \\<11 kg (kilograms) and females \\<7 kg) 25. The strength value will be normalized as a relative value in percent, calculated according to Bohannon et al. based on values of healthy individuals, considering gender and age. It will also be normalized according to height, due to the known impact of this anthropometric feature on palmar strength.\n\nThe overall motor function of the patient will be assessed using the Medical Research Council (MRC) 24 scale. The evaluation will consist of the bilateral analysis of six specific movements (shoulder abduction, elbow flexion, wrist flexion, hip flexion, knee extension, ankle dorsiflexion) through manual muscle testing, scoring from zero to five points 2 = movement without the action of gravity, 3 = movement against the action of gravity, 4 = a slight manual resistance wins, 5 = a great manual resistance wins ). The maximum score of the scale is 60 points, adding the degree of muscle strength of all muscle groups tested. If the patient is unable to have one of the limbs tested (for example: amputation) it is assumed that the limb would have the same force as the contralateral limb.\n\nIn order to standardize the position during the application of the scale and to minimize bias, the position will be adopted in the supine position, with the bed between 45º to 60º and symmetrical posture. First the patient will be asked to move freely. According to the result, manual resistance is imposed or the action of gravity is eliminated.\n\nThe indicative weakness score is 48 points or less. Individuals who score between 48 and 37 points on the MRC scale are considered to have significant weaknesses; those with 36 points or less are classified as severely weak.\n\nThe handgrip strength and the MRC scale will be compared as predictors of weaning duration of mechanical ventilation"}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Adult patients on invasive mechanical ventilation for more than 48 hours and ready to perform the spontaneous breathing test.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* age over 18 years\n* being on invasive mechanical ventilation for more than 48 hours\n* fulfill the pre-defined criteria for performing the spontaneous breathing test\n\nExclusion Criteria:\n\n\\- patients unable to perform the hand grip strength test and the MRC scale (any rheumatologic conditions, neuromuscular, amputation, cachexia, neuropsychiatric symptoms: such as confusion and delirium)'}, 'identificationModule': {'nctId': 'NCT03991702', 'briefTitle': 'Hand Grip Strength and Medical Research Council Scale as Predictors of Weaning Failure', 'organization': {'class': 'OTHER', 'fullName': 'Hospital de Clinicas de Porto Alegre'}, 'officialTitle': 'Hand Grip Strength and Medical Research Council Scale as Predictors of Weaning Failure and Duration of Mechanical Ventilation.', 'orgStudyIdInfo': {'id': '49900015.0.0000.5327'}}, 'armsInterventionsModule': {'interventions': [{'name': 'diagnostic test', 'type': 'DIAGNOSTIC_TEST', 'description': 'The overall motor function of the patient will be assessed using the Medical Research Council (MRC) scale and Palmar dynamometer strength'}]}, 'contactsLocationsModule': {'locations': [{'zip': '90035007', 'city': 'Porto Alegre', 'state': 'Rio Grande do Sul', 'country': 'Brazil', 'facility': 'Hospital de Clinicas de Porto Alegre', 'geoPoint': {'lat': -30.03283, 'lon': -51.23019}}], 'overallOfficials': [{'name': 'Gilberto Friedman, Prof', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Hospital de Clinicas de Porto Alegre'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Hospital de Clinicas de Porto Alegre', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
