16
Q

T/F CNS pathology can result in decreased neural mediated stiffness too

A

T

17
Q

why CNS can be decreased neural mediated stiffness too

A

hypotonia early after injury (spinal shock)

18
Q

what can cause joint limiation

A

client posture
alignment
speed of movement (spasticity)

19
Q

heterotrophic ossification treatment consideratsion

A

same as for other biotech limitations

20
Q

what can you not do for HO

A

no forced stretch
just acitve/ pass ROM
no casting / immbolization

21
Q

what do for HO

A

functional activity
cardio
lease with MD

22
Q

HO

A

bone forming inside soft tissue

23
Q

clinical indicators of HO

A

sudden / dramatic decrease ROM
feel a bony block

confirmed on X-ray

24
Q

what can HO be confused with

A

DVT, infection, trauma

25
Q

T/F any individual with challenged in mobility and motor function is at risk of developing biomechanic limitat

A

T

26
Q

always include __ in biomech limit patients

A

prevent / minimize loss of ROM and flexibility

27
Q

5 things you should consider in neuro population

A 
motor control
tone
flacid
neglect
sensory changes
28
Q

safety screening for neuo

A

assess sublax/ sulcus
flacid/tone
ER
AROM/PROM with humerus in ER (thumbs up)

29
Q

Overhead pulleys for hemiparetic shoulder?

A

NO, NO, NO

30
Q

condition that requires decrease mm extensibitly for function

A

tenodesis grip

31
Q

condition requires increase mm extensibility for function

A

hamstring

32
Q

does soleus or gastroc impact sit to stand

A

soleus

33
Q

treatment for biomech strategies

A

maintain ROM
anticipate loss of PROM
treat limits
consider individual needs

34
Q

goal of passive stretch

A

provide low load, long positional stretch

35
Q

t/f casting helpful with post head injury with CP

A

yes

36
Q

casting for HO or seizures?

A

no

37
Q

t/F stretch duration established in neuro population

A

no, FITT principals must be individually assessed

38
Q

contraindications for streching

A 
bony block limts
recent fracture not united
acute inflam
acute join piain
hematoma
when the contracture is helping stability
post tendon transfer surgery
39
Q

precautions for stretching

A 
dont force beyond normal PROM
newly united fraction
prolonged immboization
osteoporosis 
edema
when contractors are helping
