26
Q

major impairment with hemiparetic gait

A
  • weakness
  • Decreased paretic positive work is a major feature of hemiparetic gait and is associated with increased metabolic cost
27
Q

hemiparetic gait - balance/coordination

A
  • Standing postural control is correlated but not strongly correlated with gait function
  • But BBS is mod-highly correlated to walking endurance (6MWT)
28
Q

hemiparetic gait - selectivity/fractionation

A
  • decreased access to dorsolateral systems
  • Learned disuse
29
Q

hemiparetic gait - tone

A
  • decreased reciprocal inhibition
  • mechanical factors –joint/soft tissue mobility
30
Q

when to treat asymmetry:

A
  • initial conditions
  • early in rehab when amount of damage or prognosis remains unclear –> Can focus a bit more on essential elements too
31
Q

you can make a person post-stroke walk more symmetrically BUT…

A
  • possibly with diminished paretic limb work
  • correlates with increased metabolic cost, decreased speed, and increased asymmetry in limb mechanics
  • mechanics used to restore symmetry must be considered
32
Q

problems of progression look like:

A
  • slow (maybe related to instability)
  • profound asymmetry
  • stop-start (maybe instability or AD)
  • lack of knee flexion during swing
33
Q

lack of knee flexion during swing

A
  • Speed-related
  • Tone
  • Synergy
  • Inter-limb Coordination
  • Weakness of other muscles besides hamstrings
34
Q

Acute Gait Training

A
  • when the patient is first starting to walk
35
Q

low function acute gait training

A
  • Provide maximum stability via mat table or assistive device
  • If mat table, provide a push up block to use as handle of device
  • Support provided at hemiplegic lower extremity
  • Have cane at end of mat table or chair for sitting or an aide follow with wc
36
Q

advantages of treadmill with/without body weight support

A

rhythm, speed, endurance, hip pull off, may not force increased conscious control

37
Q

disadvantages of treadmill with/without boy weight support

A

externally driven instead of internally generated; different joint kinematic and temporal measures (e.g., leg pulled backward instead of trunk gliding forward over leg); may not be better than over-ground training.

38
Q

treatment progression problems - external support

A
  • Partial Weight Support: Usually used with treadmill locomotion but can be used over-ground
  • “Simple Support” during overground ambulation: quad canes vs. straight canes
39
Q

treatment progression problems - increase speed

A
  • Speed: use speed to “force” progression
  • While loading of the LE and speed are factors in transitions in the gait cycle (stance to swing) sufficient hip extension is the most potent sensory input to initiate swing phase.
40
Q

Treatment Progression problems - NMES/FES

A
  • PF activity increases NMES: e.g., PF’s = push-off =? Increased speed
  • ANPT Guidelines on AFO/FES
41
Q

rhythmic auditory stimulation

A
  • A musical rhythm with accentuated beats acts as a peripheral pacing signal to facilitate the locomotion pattern and produces changes in
    EMG responses
  • The tempo of the music is set to the patient’s cadence
  • Indirectly treats asymmetry
42
Q

rhythmic auditory stimulation may be useful IF

A

you do not observe increased joint motion
asymmetry or increased vertical COM motion when symmetry is achieved

43
Q

Problems of stability look like:

A

*Slow
*Stop –start
*Wide BOS
*Inconsistent step length, direction, width
*Need for assistive device
*Postural asymmetry (static or dynamic)
*Poor trunk control

44
Q

stability - early intervention/ loading using tilt table

A
  • Develop a positive extensor support moment via strengthening hip and knee extensors
45
Q

stability - need to regain HAT control

A
  • Strength and mobility: Hip extensors/flexors
  • Cues for posture/trunk position –> Verbal, visual feedback, tactile/manual
46
Q

stability - utility in of external support

A

are they aiding gait or limiting the need for the patient to make postural corrections/develop control on his own?

47
Q

stability - practice in proactive and reactive modes to challenge balance

A
  • Head turns, different self-selected directions, change step size
  • Reactive –change speed of treadmill; walk against elastic tubing and release
48
Q

stability - progressively increase balance challenge

A

Eye; head, UE movements; carrying loads; placing objects along the way to force weight shifting

49
Q

is the approach to abnormal synergy patterns about relearning isolated movement?

A

no- it is to explore external environmental conditions and change the task allowing movements to emerge (through shaping)

50
Q

most important need for adaptation:

A

stairs, ramps, curbs, obstacles, surfaces

51
Q

what does exploit environmental conditions mean?

A
  • Change surfaces, vary obstacles, practice stairs/curbs.
  • Progress from stable-uncluttered to unstable-cluttered.
52
Q

change the task (gait) through:

A

vary speed; abrupt starts and stops; changing direction; turning the head; interact with differing loads; change attentional demand

53
Q

increased workload secondary to:

A
  • selectivity
  • posture/balance
  • coordination
  • tone
  • tension generation
  • muscle/CT properties issues
54
Q

long term viability - energy expenditure

A
  • Endurance training (increase time and distance) within cardiac restrictions
  • Treat other requirements due to their interactions
55
Q

long term viability - tissue stress

A
  • treat other requirements due to their interactions
  • orthotics
56
Q

why are AFOs needed?

A

for knee and ankle stability
- should initially be used only if needed for safety of to protect joints

57
Q

which AFOs are a little better for allowing ankle movement?

A

articulated

58
Q

do AFOs allow PF push off?

A

nope

59
Q

long distance travel observations

A
  • unable to independently travel to destinations where endpoint is unseen (despite relatively high level of physical capability)
  • Behavioral factors: cognitive dysfunction: attention, memory, judgment, problem solving skills
60
Q

to increase long distance travel

A

*Progressively increase travel distance and destination goals
*Keep environment stable at first; start with simple paths
*Make a course and provide relevant sensory cues (landmarks)
*Work with written and/or graphic information to help with planning and problem solving

61
Q

what do you have to practice for use-dependent learning?

A

gait

62
Q

all affected requirements should be addressed:

A
  • Treating impairments alone will probably not improve gait function substantially
  • Intense mobility training can be effective
63
Q

gait -

A

oriented physical fitness training should be offered to all patients assessed as medically stable and functionally safe to participate, when the goal is to improve functional ambulation
