Cerebral palsy (CP) is a broad term describing a group
of nonprogressive disorders of posture and movement. The
cause of CP is multifactorial, usually attributed to events
during early brain development, and producing life-long
lesions and anomalies.1 The brain lesions manifest as sec-
ondary motor impairments, ranging from mild to severe,
and may also affect sensation, cognition, communication,
and/or behavior. The most common features are decreased
muscle strength and abnormal muscle tone.2 Because of the
motor impairments of the trunk and limbs, there is an
inability to generate enough force to maintain antigravity
postural control, thus leading to abnormal postures.3 Pos-
ture refers to the position of the limbs or body as a whole
whereas postural control is the ability to control the body’s
position in space to obtain stability and orientation.4,5 Pos-
tural control affects not only sitting and standing but also
the ability to sequence movement appropriately.4 Although
an increasing body of research has examined postural con-
trol in children with CP, it has been mostly observational
and descriptive in nature.
