30 min provide evidence of impairments outside of PT scope Hoehn-Yahr stages
36
what are the motor signs associated with PD
weakness apraxia bradykinesia akinesia rigidity postural instability gait abnormalities
37
explain weakness seen in PD? is it motor neuron weakness?
not UMN weakness, instead weakness due to disuse and rigidity of muscle
38
what's apraxia in PD due to
difficulty with automatic and voluntary movements directed through the pyramidal system
39
why is postural instability very important to address
those with PD are 2x more likely to fall
40

mask-like facial expression
43
what is the definition of rigidity
equal resistance in agonists / antagonists
44
what is the symptom reported of rigidity
heaviness and stiffness in limb
45
explain rigidity in relation to progression of PD
starts proximally in shoulders and neck and moves distally as progression occurs
46
how is LOS affected by PD
reduced, more so forward than backward directions
47
how do those with PD respond to perturbations
not well -- will not use postural control strategies due to abnormal coactivation of musculature / poor sensorimotor integration
48
how does dual tasking affect postural control in those with PD
worsens
49
why may a patient with PD experience dysphagia or dysarthria
rigidity in musculature leading to reduced ROM - can cause speech disorders
50
what are non motor clinical signs of PD
depression anxiety apathy _________ dysfunction cognitive autonomic olfactory visual / visuospatial perception vestibular auditory
51
what is sialorrhea
excessive drooling
52
what can lead to dementia in those with PD
depression
53
what autonomic dysfunction can be seen in those with PD
hypotension bowel/bladder blurry vision dyspnea orthostatic hypotension
54
how is visual and visuospatial perception dysfunction observed in those with PD
impaired postural control abnormal vestibulospinal reflexes impaired sensory integration
55
what is the pharmacological agent that is used to treat PD
levadopa/carbidopa (sinemet)
56
what is levodopa/carbidopa
gold standard for dopamine replacement
57
what is something to keep in mind when working with those on levadopa/carbidopa
needs to be on a fixed schedule & on and off times when the drug is active -- want to do PT with patient when they are "on"
58
how long after dosage does "on time" begin on levodopa/carbidopa
20-60 min
59
side effects of levodopa/carbidopa
hypotension nausea dry mouth dizziness fluctuations dyskinesia during "off times"
60
what do dopamine agonists do
stimulate dopamine receptors in basal ganglia
61
what is deep brain stimulation
multi-electrode leads implanted into thalamus
62
where is deep brain stimulation implanted
subthalamic nucleus globus palladis internus
63
what is deep brain stimulation effective for? what are the side effects
advanced PD depression, paresthesia, paresis, loss of balance, dystonia
64
what are the cardinal signs of PD? what qualifies a diagnosis
rigidity resting tremor bradykinesia postural instability 3 or more
65
how would an exam look in those with PD
cognitive screen msk screen cardiopulm screen movement analysis postural control assessment
66
what can be used to assess cognition
MMSE MOCA geriatric depression scale
67
what posture is seen typically in those with PD? how could that affect MSK screen?
flexed / stooped - kyphotic limit shoulder, spine and hip ROM
68
what is common pain wise in those with PD? why?
low back and neck pain postural abnormalities
69
what could indicate PD via cardiopulmonary screen
orthostatic hypotension
70
what outcome measures can be used to test cardiopulmonary system
2/6 MWT
71
what is looked at during movement analysis
if movements are bradykinetic if the tremor affects ADLs gait abnormalities UE function
72
what is used to test UE function
9 hold peg test
73
what is the most recommended postural control assessment in PD populations
miniBEST test
74
downward gaze palsy during neuro exam would indicate
progressive supranuclear palsy
75
what symptoms may mimic PD but are instead atypical parkinsonism
freezing of gait and/or frequent falls early in the disease
76
what would a patient present with that would cause one to think normal pressure hydrocephalus vs parkinson
urinary incontinence freezing of gait cognitive impairment (wet wobbly wacky)
77
what H&Y stage of PD is freezing of gait typically seen
3 into the late stages
78
what typically causes normal hydrocephalus
older adults that have brain tissue atrophy and CSF is allowed to build up in the ventricles over time
79
explain the difference between the current model of PD rehab and potential model
rehabilitation typically occurs once disability or acute events occur -- can be too late in the progression to really slow it down, more reactive than proactive
80
when physical therapy is applied early in progression, what is each interval of care assessed by
progression of disease and its effect on mobility, ADLs and quality of life
81
what H-Y classification is associated with early PD rehab? what is focused on intervention wise
