May:
Be transient and disappear
Preterm infants
Medically fragile children
Continue as Hypotonic CP
Later be diagnosed as Athetoid, Ataxic,
or Spastic CP
McElroy, Haynes, & Franjoine 2009
May:
Be part of an obvious or later diagnosed
genetic syndrome
Down Syndrome
Prader-Willi
Joubert Syndrome
Other syndromes
Fetal alcohol syndrome (FAS)
Fragile X syndrome
Maternal drug abuse
McElroy, Haynes, & Franjoine 2009
May be:
A muscle fiber type disorder
Sensory integration disorder
MR
Autism

Regulatory

Cardiopulmonary

McElroy, Haynes, & Franjoine 2009
Variable:
Child to child
Etiology
Cognition often underestimated
Flat affect
Appears “slow” or “lazy”
Latency of response time
McElroy, Haynes, & Franjoine 2009
Abnormally low muscle resting tone
Abnormally low resistance to being
lengthened
Feels “soft” when handled
Described as “floppy”
McElroy, Haynes, & Franjoine 2009
Impaired Muscle Activation
Insufficient Co-activation
Impaired Muscle Synergies
Inability to Initiate,
Sustain, Terminate
McElroy, Haynes, & Franjoine 2009
Holding joint positions in
midrange is difficult
Move quickly through transitions
Tend to work at end ranges
Decrease degrees of freedom
distally
Hyperextention of elbows and
knees
McElroy, Haynes, & Franjoine 2009
Difficulty initiating muscle contraction
Threshold for fiber firing
Insufficient number of fibers recruited
Slow to respond
Response is then short-lived
“Good baby”…later “lazy”
May have a flat affect
In supine “look flat”
McElroy, Haynes, & Franjoine 2009
Difficulty in sustained holding against
gravity…especially postural muscles
Look like gravity is pulling them down
Have a “belly” when upright
Often turns muscles off to quickly
i.e. Collapse when standing
McElroy, Haynes, & Franjoine 2009
Impaired Motor Execution
Impaired Modulation and
Scaling of Forces
Impaired Timing and
Sequencing
Excessive overflow of IntraInterlimb contractions
McElroy, Haynes, & Franjoine 2009
Phasic bursts of movement
Little grading – moves quickly to end
ranges
Overshoots target or strikes target
inappropriately
McElroy, Haynes, & Franjoine 2009
Primary—
Difficulty grading agonists and antagonists
Timing and sequencing difficulties may
be secondary to initiate, sustain, and
strength issues
McElroy, Haynes, & Franjoine 2009
Impaired Force Generation
Strength: the ability to contract a muscle
to a sufficient degree to impact the task
Primary
inability to reach threshold for muscle firing
inability to recruit enough muscle fibers
Secondary
Little muscle holding: decreased strength/atrophy
Changes in muscle fiber type 2°to phasic use
McElroy, Haynes, & Franjoine 2009
Anticipatory Postural Control—
Probably not a primary impairment
Difficult with latency of initiation
Often they may anticipate a movement
and “lock out their joints” in anticipation
Anticipation may be present…just not
appropriate
McElroy, Haynes, & Franjoine 2009
Poverty of Movement
“Poverty”--they don’t move much
Happy to stay in one place
Movement repertoires are somewhat
limited
Secondary to strength, alignment, and stability
available to them during development
Movements in the frontal and, especially, the
transverse planes are less frequently seen
McElroy, Haynes, & Franjoine 2009
Fractionated or Dissociated Movements
Often use pure reciprocal innervation
rather than co-contraction
Movements may be “too dissociated”
Need to control degrees of freedom to support
purposeful isolated control
Often fix distally
Splaying of fingers
Plantar-flexion of ankles
McElroy, Haynes, & Franjoine 2009
Vision
Vestibular
Somatosensory
McElroy, Haynes, & Franjoine 2009
Primary Impairments
Refractory errors
Visual field loss
Strabismus
Cortical visual impairment not as
common as in SQ
Secondary Impairment
Uses eyes for postural stabilization
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Difficulty using:
proprioceptive information
tactile information
Primary impairment
If inappropriate firing of receptors
Secondary impairment
If caused by lack of experience due to little
movement, ability to read the input didn’t
develop well
McElroy, Haynes, & Franjoine 2009
“ the ability of the nervous system
to perceive, interpret, modulate,
and organize sensory input for use
in generating or adapting motor
responses…
(Miller & Lane 2000)
Degree of difficulty varies widely by
etiology of the hypotonia
McElroy, Haynes, & Franjoine 2009
Bones:
Changes are usually secondary to static
positons
Plagiocephaly
Flattend ribcage
Kyphosis
Shoulder instability
Hip instability
McElroy, Haynes, & Franjoine 2009
Muscles:
Atrophy
Weakness
Fiber type changes
Muscle shortening
Muscle overlengthening
Connective tissue:

M R Franjoine & M P Haynes
Antigravity postures are difficult so use
phasic bursts of movement
Move quickly to ends of range
Rest on ligaments, joint capsules, and
bones
McElroy, Haynes, & Franjoine 2009
Use wide BOS in both UEs and LEs
Move quickly to ends of range
Rest on ligaments, joint capsules, and
bones
McElroy, Haynes, & Franjoine 2009
Postures:
Hyperextends neck and “rests” head back
Mouth is often open
Shoulder complex is often elevated to support
head
Lower extremities are widely abducted and
externally rotated
Movement:
Even neck extension is phasic…head may fall
forward without control
No lateral weight shifts!!!!
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Postures:
Prefers arms abducted and legs abducted
Body “melted” onto the floor
Movement:
Antigravity of extremities difficult
Sometimes “walks” extremities with hand
movements
Can’t lift head against gravity
“Flings” extremities
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Postures:
Retains flexed spinal position with
hyperextended head resting position
Sometimes looks like their chest “folds” in
front
Uses UEs for support (hyperextended
elbows)
May use feet as hands
Posteriorly tilted pelvis
BOS is very wide, knees flexed or extended
McElroy, Haynes, & Franjoine 2009
Movement:
Keeps the COM in the middle of the BOS
Will pivot rather than rotate spine
Often transitions out of sitting in the sagittal
plane with legs abducted
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Postures:
Hyperextension at the neck and elbows
UEs abducted
Hips and knees flexed greater than 90°
Hips abducted
Movement:
Moves extremities rapidly with longer
periods of 4s support with extremities
“locked” when possible
Much rather scoot on bottom!!!
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Postures:
Support with UEs
Hips are abducted
Hips rest on feet or floor
Movement:
Difficult position to maintain
Will not transition to ½ kneel, pushes with
legs at the same time to get to standing
McElroy, Haynes, & Franjoine 2009
McElroy, Haynes, & Franjoine 2009
Postures:
Still like hyperextended neck and kyphotic
upper spine
UEs used to increase stiffness of trunk
Pelvis may be anteriorly or posteriorly tilted
Wide BOS in LEs
Knees hyperextended, out-toeing
McElroy, Haynes, & Franjoine 2009
Movement:
Legs may “fold” unexpectedly
Difficulty shifting weight laterally to
unweight one leg for gait
Wide BOS and short steps make gait
awkward and inefficient

• Independent, efficient
upright mobility difficult
• Coordination and safety is
a concern
COMMUNICATION • Though may be difficult to
understand, communication
is usually verbal
• Usually can master ADLs
BASIC ADL’S
• May be more limited by
cognition than motor ability

M R Franjoine & M P Haynes
Accepted by family…”good child” or
“lazy child”
Often not accepted by peers due to
latency of responses and communications
Sometimes problems safely accessing
playgrounds and community centers
McElroy, Haynes, & Franjoine 2009
Work upright whenever possible
Attend closely to alignment
Narrow the base of support
Emphasize weight shifts
May need to increase attention and/or
arousal
McElroy, Haynes, & Franjoine 2009
Increase proprioception by activating cocontraction around joints…holding and
graded movements
Build strength working in midranges…
concentric and eccentric
McElroy, Haynes, & Franjoine 2009
“Good” babies and children are often
ignored
The static situation of these children
interferes with exploration and learning
Don’t under-estimate the power of the
biomechanical limits these children face.
