Conclusions There is considerable variability in the type of measures utilized to measure physical impairments and limitations in survivors of critical illness .
Purpose To identify measures used to evaluate the broad constructs of functional impairment and limitations in the critically ill across the continuum of recovery , and to evaluate , synthesis e and compare the clinimetric properties of the measures identified .
Global Muscle Strength But Not Grip Strength Predicts Mortality and Length of Stay in a General Population in a Surgical Intensive Care Unit
Background Paresis acquired in the intensive care unit ( ICU ) is common in patients who are critically ill and independently predicts mortality and morbidity . Manual muscle testing ( MMT ) and h and grip dynamometry assessment s have been used to evaluate muscle weakness in patients in a medical ICU , but similar data for patients in a surgical ICU ( SICU ) are limited . Objective The purpose of this study was to evaluate the predictive value of strength measured by MMT and h and grip dynamometry at ICU admission for in-hospital mortality , SICU length of stay ( LOS ) , hospital LOS , and duration of mechanical ventilation . Design This investigation was a prospect i ve , observational study . Methods One hundred ten patients were screened for eligibility for testing in the SICU of a large , academic medical center . The Acute Physiology and Chronic Health Evaluation ( APACHE ) II score , diagnoses , and laboratory data were collected . Measurements were obtained by MMT quantified with the sum ( total ) score on the Medical Research Council Scale and by h and grip dynamometry . Outcome data , including in-hospital mortality , SICU LOS , hospital LOS , and duration of mechanical ventilation , were collected for all participants . Results One hundred seven participants were eligible for testing ; 89 % were tested successfully at a median of 3 days ( 25th–75th percentiles=3–6 days ) after admission . Sedation was the most frequent barrier to testing ( 70.6 % ) . Manual muscle testing  was identified as an independent predictor of mortality , SICU LOS , hospital LOS , and duration of mechanical ventilation . Grip strength was not independently associated with these outcomes . Limitations This study did not address whether muscle weakness translates to functional outcome impairment . Conclusions In contrast to h and grip strength , MMT reliably predicted in-hospital mortality , duration of mechanical ventilation , SICU LOS , and hospital LOS
