Q

What is the definition for Cerebral Palsy?

A

“A group of permanent disorders of the development of movement and posture, causing activity limitations that are attributed to non-progressive (nerve lesion) disturbances that occurred in the developing fetal or infant brain”

Q

What birth has the highest likelihood of producing a CP child? Why?

A

Triplets.
When multiple babies are in the womb, the placenta has to accommodate/deliver more nutrients and oxygen to the babies. In triplets, the placenta acts as if there are 2 babies, instead of 3, so there is an increased chance one child will not get enough oxygen and have CP.

A

Balance is primary goal in PT

131
Q

A

Increased muscle tone in antigravity muscles

132
Q

Hip flexors, adductors, internal rotators, knee flexors, ankle plantarflexors, scapular retractors, glenohumeral extensors and adductors, elbow flexors, forearm pronators.

133
Q

What other deficits may be present in those w/ CP?

A

Possible visual, auditory, cognitive, and oral motor deficits

134
Q

Common impairments w/ ataxic CP (7):

A
  • Low postural tone

Q

NSCA Guidelines for Strength Training

A
  • Warm up: 5-10 minutes
  • Type: single & multi-joint; concentric and eccentric
  • Intensity/volume: 1-3 sets of 6-15 reps 50-80% of 1 RM
  • Rest Intervals: 1-3 minutes
  • Frequency: 2-4 x/week
  • Duration: 8-20 weeks
  • Progression: Inc resistance gradually (5-10%)
