Online identification and nonlinear control of the electrically stimulated quadriceps muscle [PDF]

, 2005
A new approach for estimating nonlinear models of the electrically stimulated quadriceps muscle group under nonisometric conditions is investigated. The model can be used for designing controlled neuro-prostheses. In order to identify the muscle dynamics

Relationship between modified Nutrition Risk in the Critically Ill (mNUTRIC) Score and nutrition intake with quadriceps femoris muscle thickness in critically ill patients

Qanun Medika: Jurnal Kedokteran Fakultas Kedokteran Universitas Muhammadiyah Surabaya, 2021
Muscle wasting in critical illness is seen from inadequate nutrition intake and stress catabolism. Modified Nutrition Risk in the Critically Ill (NUTRIC) Score is a screening tool that measures starvation, inflammation, disease severity, and organ ...

Quadriceps muscle strength in scoliosis [PDF]

European Respiratory Journal, 2009
Quadriceps muscle weakness is an important component of chronic obstructive pulmonary disease (COPD). We hypothesised that quadriceps weakness would also be a feature of restrictive lung disease due to scoliosis.We studied 10 patients with severe scoliosis (median (interquartile range (IQR)) forced expiratory volume in 1 s (FEV1)35.3 (11)% predicted ...

Quantitative sonographic assessment of quadriceps muscle thickness for fall injury prediction in patients undergoing maintenance hemodialysis: an observational cohort study

BMC Nephrology, 2021
Background Accidental fall risk is high in patients undergoing maintenance hemodialysis. Falls are associated with fatal injury, comorbidities, and mortality. Risk assessment should be a primary component of fall prevention.
