Flashcards in OS T#1: S1 Deck (71):
At what angle of the knee is the MCL most responsible for knee stability?
At what angle do you hold the patients knee for Lachmans test?
between full ext and 30 degrees and slight lateral rotation on the tibia
What is a mandated reporter?
mandated reporters are people who have regular contact with vulnerable people and are therefore legally required to ensure a report is made when abuse is observed or suspected.
general or local insensibility, as to pain and other sensation, induced by certain interventions or drugs to permit the performance of surgery or other painful procedures.
insensitivity to touch
Loss of the ability to sense weight
the inability to feel pain (while conscious)
Pain that results from a non-injurious stimulus to the skin.
constant relentless burning hyperesthesia and hyperalgesia that develops after a peripheral nerve injury
Disorientation of any of the senses (especially touch)
heightened sense of touch
heightened sense of pain
severe and multiple shock like pains that radiate from a specific nerve distribution
loss of vibratory sensation
abnormal sensations such as tingling, pins and needles, burning or numbness
A condition with involuntary movements combined with postural instability
A muscular twitch that is caused by random discharge of LMN, it suggests LMNL although it can be benign
a muscular twitch involving muscle fibrils that is not visible suggests UMNL
What are the common symptoms of Lymphedema?
Swelling, decreased ROM, achy heaviness, a feeling of fullness, brawny, fibrous non pitting edema.
What may be observed with cancer patients during ther ex
increased fatigue: elevated HR and BP, dyspnea, pallor, sweating
What hematological issues are possible with cancer treatment?
Leukopenia, Thrombocytopenia (decreased platelets), anemia
What is an open skill?
An open skill is a skill where the environment is constantly changing and so movements have to be continually adapted.
What is a closed skill?
These skills take place in a stable, predictable environment and the performer knows exactly what to do and when.
What is an internally paced skill?
This is a skill in which the performer controls the rate at which the skill is executed.
What is an externally paced skill?
This is a skill in which the environment, which may include opponents, controls the rate of performing the skill.
What is a discrete skill?
Brief, well-defined actions that have a clear beginning and end.
What is a serial skill?
A group of discrete skills strung together to make a new and complex movement.
What is a continuous skill?
A skill that has no obvious beginning or end. The end of one cycle of movements is the beginning of the next, and the skill is repeated like a cycle.
What foot position correlates with a rigid lever arm?
What position is the foot in during initial contact (heel strike)?
What position is the foot in during foot flat (loading response)?
What position is the foot in during midstance?
What position is the foot in during heel off?
What position is the foot in during toe off?
In what position should joint play be performed?
Open packed position
What three motions make up supination?
Inversion, Adduction, and Plantarflexion
What three motions make up pronation?
Eversion,Abduction and Dorsiflexion
Injury to a nerve that creases transient loss of function. (ex: conduction is blocked due to ischemia) nerve dysfunction is rapidly reversed (weeks)
Injury to to the nerve interrupting the axon and casing a loss of function and Wallerian degeneration. There is no disruption to the endoneurium and regeneration is possible.
A cutting of the nerve with severance of all structures and complete loss of function. Regeneration generally fails without surgical intervention.
Signs and symptoms of LMNL
Hypotonia,absent reflexes, or flaccidity
How to diagnose LMNL's
Nerve conduction velocity tests (slower or complete block)
EMG for nerve fuction check for fibrilations
What is evidence of reinnervation as seen on an EMG?
Low amplitude, short duration, polyphasic motor unit potentials
How do you propel a hemi-wheelchair?
With one arm and the ipsilateral leg.
What is a contraindication to a one arm drive wheelchair?
What influences a persons ability to perform normal vital capacity, Forced expiratory volume in 1 sec (FEV) and total lung capacity?
What is Functional residual capacity limited by
resting end expiratory pressure
what is Resting end expiratory pressure (REEP)
REEP is Resting end expiratory pressure, The equilibrium point where forces of inspiration and expiration are balanced.
Occurs at the end of tidal respiration.
What is considered a hypomobile patella?
When performing lateral glide and patella moves less than 1 quadrant
What is considered a hypermobile patella?
When the patella moves more than 2 quadrants with a lateral glide
At what angle is the ACL least stressed?
Medial rotation of the knee causes which structures to become taut and which to become slack?
ACL and PCL taut and collaterals slack
Lateral rotation of the knee causes which structures to become taut and which to become slack?
ACL and PCL slack and collaterals taut
At what angle is the majority of the PCL taut?
30 degrees of flexion
Which 3 nerves come from the anterior portion of the brachial plexus?
Musculocutaneus, median and ulnar
Which two nerves come from the posterior division of the brachial plexus?
Axillary nerve and the Radial nerve
What is class III heart diseased marked by?
Limitation of physical activity, less than ordinary physical activity causes fatigue, palpitations, dyspnea, angina pains
What are the adverse reactions of Digoxin
fatigue, headache, muscle weakness, bradycardia,ventricular fibrillation, and super ventricular arrhythmias
Normal reactions to Digoxin are:
Confusion/ memory loss, tachycardia, and involuntary movements/ shaking.

What polarity is Copper and magnesium? (muscle spasms)
What polarity is Dexamethasone?
What are the side effects of long term corticosteroid use?
osteoporosis, weakened supportive joint structures, muscle wasting.
After how many weeks does muscle hypertrophy begin?
Characteristics of Venous ulcer
irregular boarders, dark pigmentation, shallow, near medial malleolus is most common.
Characteristics of Arterial ulcer
irregular edges, painful (especially when legs are elevated)
