Reliability in using the modified Gross Motor Function Measurement-66 Thai version by Physical Therapy students

Abstract

The motor assessment tool in children is very limited in Thai.  The purpose of this study was to determine the reliability in Thai Physical Therapy students, using the Modified Gross Motor Function Measurement-66.  The Modified GMFM-66 was developed from the GMFM-66 & GMFM-88 and the Modified GMFM-88 in Thai version.  Two cerebral palsied children were assessed by using the Modified GMFM-66 Thai version, taping with VCD and scoring the evaluation according to Modified GMFM-66 scoring system. Then the third year Physical Therapy students who have never use GMFM, were instructed the Modified GMFM-66 Thai version and evaluated both children through VCD.  The over 70 percent agreement was signified for the reliability of using the Modified GMFM-66 Thai version.  The data was analyzed by using descriptive statistic in percentage, mean and standard deviation. The results from 113 students who scored both children demonstrated the over 70 % agreement in all dimensions at 79.87 ± 7.79 and 87.16 ± 6.18 %.  The number of students who was unable to pass the agreement of using the Modified GMFM-66 Thai version in the two CP were 11.50 % and 3.9 % respectively.  Therefore, the Modified GMFM-66 Thai version was proved as a reliable tool and suitable for clinical teaching in Thai physical therapy students.  It is believed that if the students practice this tool regularly, the Modified GMFM-66 Thai version will be more accountable in movement assessment in pediatric Physical Therapy clinic.
