Abstract
B. Lindmark motor assessment (BLMA) is an instrument designed for evaluation of functional capacity after stroke. The objective of this study was to evaluate intra- and inter-rater reliability of the BLMA from assessments of videotaped examinations with the BLMA. Three physiotherapists served as raters and 21 acute stroke patients, with different levels of impairment, served as subjects for the videotapes. The videotaped examinations were viewed and scored by the raters individually on two occasions. Kappa statistics were used for calculation of reliability. For intra-rater reliability, the kappa values for the paretic side ranged from 0.43 to 1 and from 0.66 to 0.84 for mobility and balance. For inter-rater reliability, the kappa values for the paretic side ranged from 0.46 to 1 and from 0.45 to 0.86 for mobility and balance. It can be concluded that the BLMA has a good intra- and inter-rater reliability in an acute stroke care setting.
