Section II. Description of the PDMS-2
The Peabody Developmental Motor Scales - Second Edition (PDMS-2) is composed of six subtests that measure
interrelated abilities in early motor development. It was designed to assess gross and fine motor skills in children from
birth through five years of age.
Reflexes (Re) - This subtest measures aspects of a child's ability to automatically react to environmental events.
Because reflexes typically become integrated by the time a child is 12 months old, this subtest is given only to children
ages 2 weeks through 11 months.
Stationary (St) - This subtest measures a child's ability to sustain control of the body within its center of gravity and
retain equilibrium.
Locomotion (Lo) - This subtest measures behaviors that children use to transport themselves from one place to another,
such as crawling, walking, running, hopping, and jumping forward.
Object Manipulation (Ob) - This subtest measures a child's movements needed to catch and throw objects. Because
these skills do not become apparent until a child reaches 11 months of age, this subtest is only given to children ages 12
months and older.
Grasping (Gr) - This subtest measures a child's ability to use his or her hands. It begins with the ability to hold an object
with one hand and progresses up to actions involving the controlled use of the fingers of both hands to button and
unbutton garments.
Visual-Motor Integration (Vi) - This subtest measures a child's ability to use his or her visual perceptual skills to perform
complex eye-hand coordination tasks such as reaching and grasping for an object, building with blocks, and copying
designs.
All of the PDMS-2 subtests contribute to a Total Motor Quotient (TMQ). This score can most appropriately be thought of
as the best estimate of overall motor abilities. In addition, each subtest contributes to either the Gross Motor Quotient
(GMQ) or the Fine Motor Quotient (FMQ) score.
Gross Motor Quotient (GMQ) - This quotient measures the ability to utilize the large muscle systems to move from place
to place, assume a stable posture when not moving, react automatically to environmental changes, and catch/throw
objects. High scores on this composite are made by children with well-developed gross motor abilities. These children
would have above average movement and balance skills. They are likely to be children who could be described as agile,
well-coordinated, and graceful in their movements. Low scores are made by children who have weak movement and
balance skills. These children may have difficulty in learning to crawl, walk, and run. A deficit in gross motor abilities can
be mild and the child's movements may be described as clumsy and uncoordinated. More severe gross motor problems
may limit a child's use of their legs to such a degree that they will need assistance to move from place to place.
Fine Motor Quotient (FMQ) - This quotient measures a child's ability to use his or her hands and arms to grasp objects,
stack blocks, draw figures, and manipulate objects. High scores on this composite are made by children with
