Content and psychometric properties of children's motor function and activity measurements using ICF / 中国康复理论与实践

ABSTRACT

Objective To analyze the content and psychometric properties of measurement tools for children's gross motor function and activity. Methods Six measurement tools for children's gross motor function and activity were selected,including Gross Motor Function Measure(GMFM),Bruininks-Oseretsky Test of Motor Proficiency-Second Edition(BOT-2),Peabody Developmental Motor Scales-Second Edition(PDMS-2),Movement Assessment Battery for Children-Second Edition(MABC-2),Test of Gross Motor Development-Third Edition(TGMD-3)and Functional Movement Screen(FMS).International Classification of Functioning,Disability,and Health(ICF)linking rules,categories and coding were used to analyze the content of measurement dimensions and items of these six tools,and their psychometric properties were explored. Results For the body function,the content of these six tools primarily addressed neuromusculoskeletal and movement-re-lated functions(b7),such as mobility of joint functions(b710),stability of joint functions(b715),muscle power functions(b730),motor reflexes functions(b750),control of voluntary movement functions(b760),supportive functions of arm or leg(b7603)and gait patterns functions(b770).For the activities and participation,the content primarily addressed mobility(d4),such as changing and maintaining body positions(d410,d415),transferring oneself(d420),walking(d450),running(d4552),and jumping(d4553).GMFM was good in inter-rater and test-retest reliability;BOT-2 was good in inter-rater reliability,test-retest reliability and internal consistency;PDMS-2 was good in inter-rater and test-retest reliability;MABC-2 was good in test-retest reliability and internal consis-tency with an excellent model fit;TGMD-3 was good in internal consistency and test-retest reliability;and FMS was good in internal consistency and test-retest reliability. Conclusion The six tools for motor and activity function measurement primarily concern neuro-musculoskeletal and movement-related functions(b7)for ICF body function,and mobility(d4)for activities and participation.PDMS-2 is suggested for a comprehensive evaluation of children's motor functions and activities;TGMD-3 and GMFM for gross motor functions;and BOT-2,MABC-2 and FMS for motor development,coordination and functional movement patterns.BOT-2,PDMS-2,MABC-2 and TGMD-3 are norm-referenced measures,whereas GMFM and FMS are criterion-referenced.Norm-referenced tools,due to their established norms tailored for various ob-jectives,boast superior psychometric properties and wider applications.All the six tools exhibit good to excellent reliability,and internal consistency coefficients ranging from moderate to excellent.Their validity also spans from moderate to excellent.
