Internal consistency of dynamometer measurements in healthy subjects and stroke patients.
Measurements of strength from six muscle groups described in two previously completed reports were analyzed further using Cronbach alpha. The coefficients were greater than .948 for a small sample of stroke patients and a larger sample of healthy individuals. This finding shows in diverse samples that the measures possess internal consistency and are measuring the same underlying construct.
