Respiratory Function and Grip Strength in the Acute Phase of Stroke Are Associated with Stroke Severity and Disability at Hospital Discharge

Table 7

Association between respiratory function and grip strength and the degree of dependence, as measured by the Barthel index, at discharge and 90 days after discharge.
