Proactive/Anticipatory balance
Ability to generate postural adjustments prior to the onset of and during voluntary movement for the purpose of either countering an upcoming postural disturbance due to voluntary movement or realigning the body’s center of mass prior to changing the base of support. This includes the ability to adapt motor behavior to meet the demands of different task and environmental conditions.
46
Reactive balance
Ability to respond to sensory input that signals a need for a response to ensure successful maintenance of postural control. The need for a response is unanticipated but may be generated externally (perturbation originating external to body) or secondarily to an internally generated movement. This includes the ability to adapt motor behavior to meet the demands of different task and environmental conditions
47
Ankle strategy
Used when sways are small and slow Move COM of body as a block about ankle joints Muscles are activated distal-to-proximal During forward sway, gastrocnemius  hamstrings paraspinals During backward sway, tib ant  quads  abdominals Used on firm support surface
48
Hip strategy
Used with larger and/or faster sways Moves COM by flexing/extending/abd/adducting hips Muscles are activated proximal to distal Forward sway, abdominals  Quads. Backward sway, paraspinals  Hamstrings Used when support surface is small/narrow/compliant
49
Suspension strategy
Moves COM down by flexing hips/knees and flexing trunk May progress to squating

64
Optic Nerve- CN II examination
Using a Snellen eye chart, ask the patient to read the lines with progressively smaller letters. Using a penlight, shine the light obliquely into the patient’s eye. A normal response is constriction of the contralateral (opposite) pupil, although the ipsilateral pupil should also constrict (see test for CN III)

A CN 3 lesion causes...
the ipsilateral eye to look laterally and down (pulled by unopposed muscles innervated by CNs 4 and 6)
77
A CN 4 lesion causes...
the ipsilateral eye to look slightly upward because the actions of muscles innervated by CNs 3 and 6 are unopposed.

The patient should feel the touch equally on the right and left sides Palpate the patient’s masseter and temporalis muscles bilaterally for strength of contraction as he or she clenches the jaw Ask the patient to hold the jaw open slightly and then provide resistance to mandibular closing or lateral motion. The patient should be able to hold the position against moderate force
80
Facial Nerve- CN VII
Assess motor function by asking the patient to smile, frown, elevate or depress the eyebrows, and puff out the cheeks Assess for symmetry of facial expression Ask the patient to close his or her eyes and stick out the tongue. Taste may be assessed by placing something sweet (piece of hard candy or drop of sweet liquid) on the anterior portion of the tongue and asking the patient to identify the taste 
81
CN VII lesion may result in...
Impaired lacrimation (tear production to clean/lubricate the eyes) Impaired taste on the anterior 2/3 of the tongue Impaired corneal “blink” reflex
82
Vestibulocochlear Nerve- CN VIII
The patient’s eyes should be closed. Hearing can be assessed by rubbing the pads of your thumb and index finger together next to one of the patient’s ears and asking for indication of when the rubbing is heard Bilaterally symmetrical hearing is expected unless a known hearing loss is present. Test one ear at a time.
83
Rinne Test (Special Test)
Place and hold the stem of a vibrating tuning fork on the mastoid bone; when the patient no longer hears it, move the vibrating tuning fork tines into the air approximately 1 in from the ear canal Sound is conducted through air approximately twice as long as it is conducted through bone, and therefore the patient should be able to continue hearing the vibrating tuning fork after it is removed from the mastoid process.
84
Weber Test (Special Test)
Place and hold the stem of a vibrating tuning fork on the top of the patient's head; ask the patient if the sound is louder in one ear than the other. Normally the sound is equally loud in both ears.
85
Glossopharyngeal Nerve, and Vagus Nerve- CN IX and CN X
Taste is assessed as with CN VII, but the flavor of the candy or liquid should be sour or bitter and should be placed on the posterior third of the patient’s tongue. Ask the patient to open his or her mouth and say “ahh.” Observe the uvula (no lateral deviation should be present) and listen for loss of phonation (CN X) Ask the patient to swallow several times; observe for and ask about any difficulty with this action. Test the gag reflex by carefully moving the tongue depressor toward the back of the patient’s throat until the gag reflex is elicited. (CN IX)
86
Spinal Accessory Nerve- CN XI
Ask the patient to shrug his or her shoulders. Press downward, asking the patient to hold the position The patient should be able to resist your force bilaterally. Observe for atrophy of the trapezius or sternocleidomastoid muscles (compare side to side).
87
Hypoglossal Nerve- CN XII

initial stage, trying out a variety of strategies (abandoning those that don’t work and carrying on with what works), needs a lot of attention and conscious effort, performance quite variable, makes many mistakes, improvements can be large
113
Associative stage
by now best strategy is selected, makes less mistakes, practices more and more to refine the skill, needs less attention, improvements are slower/smaller
114
Autonomous stage
performance mostly automatic, can divert attention to other tasks (paying too much attention to elements of task can reduce performance!)
115
Bernstein’s 3 stage model
mastering the degrees of freedom. The 3 stages are novice, advanced, and expert. Talks about releasing degrees of freedom at different joints with higher stages, eg – learning to use a hammer using just elbows, then wrist, then wrist, elbow, shoulder Releasing degrees of freedom allows for more efficient and flexible movements according to task and environment demands. external support may be needed in early stages

120
Distributed practice
Divide 30 reps into smaller chunks, 5 trials now, 5 more after 10 mins, and so on. The amount of rest between trials is equal to or greater than the amount of time for the trial
121
Constant practice

122
Variable practice
Practice of a given task under variable conditions Better for retention and transfer of skill
123
