The GMPM is an observational instrument to be used in the evaluation of gross motor performance (i.e., quality of movement) in children with cerebral palsy. The instrument's primary purpose is to evaluate change over time in specific qualitative features, or attributes, of gross motor behaviour.
To order the GMPM: The GMPM is available from the Social Program Evaluation Group at Queen's University in Kingston, Ontario, Canada. Send an email to spegmail@educ.queensu.ca. Include the name of the measure (i.e., GMPM) in your message.
Cost of the manual: Cost information is available from the Social Program Evaluation Group at Queen's University.

More information about the GMPM: The purpose of the GMPM is to evaluate change over time in gross motor performance (i.e., quality of movement) in children with cerebral palsy. The GMPM was validated on a sample of children with cerebral palsy aged 5 months to 12 years.
Twenty (20) items assess 5 attributes of gross motor performance - alignment, coordination, dissociated movement, stability, and weight shift. The GMPM may be used in conjunction with the Gross Motor Function Measure (GMFM). The GMPM is a criterion referenced observational measure. There is evidence of inter-rater (ICC = 0.93, n = 26), intra-rater (ICC = 0.92, n = 28), and test-retest reliability (ICC = 0.96, n = 28). The GMPM discriminates between groups of stable subjects and subjects who, in the judgement of therapists show clinically important change. Construct validity based on parent and video judgements has not yet been demonstrated. The GMPM uses a 5-point scale. Guidelines are required for administration and scoring. Average percent scores are calculated for attributes and total. Takes 45 to 60 minutes to administer.
There is a new version of the GMPM that is specifically designed for use with children ages 4 and up who are in GMFCS Levels I, II and III, and focuses on quality of movement related to ambulatory skills. It is called Quality FM.
