Q

Where is the most struggle in muscle activation post stroke?

A

Shortened ROM of muscles especially with increased velocity (compensate by functioning in midrange - bend knees so quads are not fully shortened)

Q

What are the muscle fiber changes post stroke?

A

Disuse atrophy after 4-6 weeks

Type 2 fiber selective atrophy

Increased % of type 1 fibers

23
Q

Why does weakness occur in TBIs?

A

Central neural activation deficits with impaired ability to activate motor units

24
Q

Why does weakness occur in MS?

A

Disruption of spinal pathways to motor unit pool (muscle fatigue and reduced force production)

25
Q

What is Parkinson’s more so about rather than weakness?

A

Initiation, timing, and sequencing

26
Q

What is Parkinson’s impacted by?

A

Changes in muscle tone

27
Q

What occurs in GBS?

A

LMN presentation (distal to proximal weakness symmetrically)

28
Q

What occurs in ALS?

A

UMN and LMN presentation (effects hand/trunk first)

29
Q

What occurs in myasthenia gravis?

A

LMN presentation (affects high use muscles first)

30
Q

What occurs in post polio syndrome?

A

LMN presentation (prone to overuse)

31
Q

What occurs in charcot Marie tooth?

A

Hereditary LMN presentation (progressive wasting)

32
Q

What makes for most transfer of increased strength to increased function?

A

Specificity of training

33
Q

What should be combined with strength training in MS?

A

Aerobic training to improve fitness, function, and QOL

34
Q

How should strength training occur in those with mild to moderate MS?

A

2x a week at moderate intensity

35
Q

How should strength training occur in those with moderate or severe MS?

A

Maintain strength and prevent decline

36
Q

When should you not strength train in GBS?

A

While progressive it is contraindicated

37
Q

How should you incorporate strength training in GBS once they are stable?

A

Progress from active assist to active to resistive

38
Q

Why should you train affected muscles in ALS?

A

They are impacted by spasticity

39
Q

How should you train muscles that are not yet affected in ALS?

A

Submaximal strengthening

40
Q

What are the muscles that are key to prevent weakness in ALS?

A

Posture and respiration muscles

41
Q

When should you not strengthen in myasthenia gravis?

A

During active crisis

42
Q

How should you strengthen in myasthenia gravis?

A

Maintenance of non affected areas and strengthening affected areas post crisis

43
Q

How do you train muscle that are 4+/5 in post polio syndrome?

A

Moderate to vigorous exercise

44
Q

How do you train muscle that are 3+ to 4/5 in post polio syndrome?

A

Exercise cautiously

45
Q

How do you train muscle that are 3 or below in post polio syndrome?

A

Stretching and protection (no resistance)

46
Q

How should strengthening occur in those with charcot Marie tooth?

A

Strengthening above affected area and compensations

47
Q

What is the key thing we need to look out for when training in most people with neuromuscular disorders?

A

Overuse and fatigue

48
Q

What are the types of interventions done to help weakness in neurological disorders?

A

NMES

Electromyographic feedback

PNF

Progressive resistive exercise

Isokinetic exercise

Task specific strength training

49
Q

What does electromyographic feedback best help do?

A

Train the timing of muscle contraction (very weak muscles)

50
Q

What should intensity be at for strength training in neurological disorders?

A

60-80%

51
Q

How should NMES be used for neurological disorders?

A

Very weak muscles (make functional if possible)

52
Q

How should progressive resistive exercise be used for neurological disorders?

A

Focus on quality (3+/5 strength is best)

53
Q

How should isokinetic be used for neurological disorders?

A

Teach how to safely use for progressing to independent

54
Q

How should aquatics be used for neurological disorders?

A

Supported movement

Can offer resistance and input
