Muscle Thickness and Echo Intensity by Ultrasonography and Cognitive and Physical Dimensions in Older Adults. Diagnostics. 2021 Aug 13;11(8):1471.http://hdl.handle.net/10668/4087The purpose of the present study was to investigate the associations between muscle thickness and echo intensity with cognitive and physical dimensions like functional capacity measured in older people. This cross-sectional study involved 20 older adults (15 women and 5 men, mean age ± SD: 85 ± 7 years, body mass index: 25 ± 3 kg/m2) from a geriatric centre in Malaga (Spain). Anthropometric measurements, cognitive assessment with Pfeiffer Short Portable Mental Status Questionnaire and Motor Memory test, Physical Performance with Short Physical Performance Battery, and muscle strength were tested. Additionally, using B-mode ultrasonography, images of wrist flexors, biceps brachii, rectus femoris, vastus lateralis, medial gastrocnemius, and tibialis anterior were captured, and muscle thickness and echo intensity variables were extracted. An association between muscle parameters assessed by ultrasonography and cognitive and physical dimensions were found in older people. Echo intensity was the best predictor in a set of regression models with different muscle parameters and a battery of cognitive and physical tests in older people. Echo intensity adjusted by handgrip strength could be a low cost and ambulatory index and an indirect and reversible indicator of functional capacity.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/SarcopeniaMuscle ultrasoundMuscle qualityPhysical cognitive performanceBody mass indexUltrasonographyÍndice de masa corporalUltrasonografíaFuerza muscularMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Persons::Persons::Age Groups::Adult::AgedMedical Subject Headings::Anatomy::Musculoskeletal System::Muscles::Muscle, Skeletal::Quadriceps MuscleMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Study Characteristics as Topic::Epidemiologic Studies::Cross-Sectional StudiesMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Muscle Strength::Hand StrengthMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Physical Examination::Body Constitution::Body Weights and Measures::Body Mass IndexMedical Subject Headings::Geographical Locations::Geographic Locations::Europe::SpainMedical Subject Headings::Anatomy::Body Regions::Extremities::Upper Extremity::Hand::WristMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Imaging::UltrasonographyMedical Subject Headings::Psychiatry and Psychology::Psychological Phenomena and Processes::Mental Processes::Cognitionresearch article34441405open access10.3390/diagnostics110814712075-4418PMC8391851
