57
Q

Children walk indoors and outdoors and climb stairs holding onto railing. Limitations walking on uneven surfaces and inclines and walking in crowded or confined spaces.

What level on GMFM would this describe?

A

Level II

58
Q

What is an assessment is often used for assessing spasticity?

A

Modified Ashworth Scale

What types of movement are associated with Dyskinetic?

A

Athetosis, rigidity, tremor, dystonia, ballismus, and choreoathetosis

86
Q

What is Athetosis?

A

slow, involuntary, convoluted, writhing movements

87
Q

What is Ballismus?

A

uncoordinated swinging of the limbs and jerky movements

88
Q

What is Dystonia?

A

neurological movement disorder, in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures.

89
Q

What is choreoathetosis?

A

occurrence of involuntary movements in a combination of chorea (irregular migrating contractions) and athetosis (twisting and writhing).

90
Q

What is the definition of Ataxic?

A

Disorder of balance and control in the timing of coordinated movements

Q

A deficit in the ______ is associated with Ataxic

A

Cerebellum

93
Q

If a person has Ataxic CP, What type of therapy is going to be the most effective and why?

A

Task- Specific… because they have difficulty with transference skills
(If this person has difficulty reaching for a cup with control – you cannot mimic the activity and expect them to carry through with it in their every day activity)
