Nope – we don’t make assumptions in this case. Only testable muscle groups count. You can include key and non-key muscle groups.
AIS B injuries are sensory incomplete AND motor complete. To be sensory incomplete, one must have sensation in the lowest sacral segments. This can be met in two ways: (1) light touch or pinprick preserved at S4-5, OR (2) deep anal pressure. To be motor complete, one must not have voluntary anal contraction AND no motor function more than three levels below the neurological level of injury.
The example you outlined (no VAC, 5/5 T1 MMT, sensation intact to T11, 0/5 MMT in BLE) is an example of an AIS B injury. Assuming strength and sensation are normal above T11, the person would have a neurologic level of injury of T11. All muscle groups below T11 were 0/5 and there is not voluntary anal contraction – making this a sensory incomplete injury (AIS B).
Hi Alex,
I think you are confusing tilt and recline. Tilt tips the whole chair without changing the seat-to-back angle (think of sitting in a dining room chair and leaning back so the front legs come off the floor). Recline opens up the seat-to-back angle (think of a recliner).
In a normal distribution, 95.4% of scores fall within 2 standard deviations of the mean, but that is not exactly what the question was asking. The question asked what percentage scored below 112 (2 standard deviations above the mean) – not what percentage of patients scored between 88 and 112. You know that 100% of patients to the left of the mean scored under 112.
Hi Alex,
Weak plantarflexors could absolutely lead to uncontrolled tibial advancement and, therefore, knee flexion during stance phase.
They could also cause knee hyperextension. Individuals with profound hamstring and/or plantarflexor weakness may have knee hyperextension in mid-stance due to a lack of eccentric control of knee extension (i.e., normally functioning hamstrings or plantarflexors could prevent the knee from snapping into hyperextension).
Hi Alex,
For the Barthel Index, both of these values are associated with a favorable outcome with different levels of sensitivity and specificity:
>95 (sensitivity 85.6%; specificity 91.7%)
>90 (sensitivity 90.7%; specificity 88.1%)
>75 (sensitivity 95.7%; specificity, 88.5%)Mini-BESTest scores of less than 22 or 23 (depending on the study you look at) are associated with increased risk of falling in Parkinson’s disease. There is one study that found scores less than 17.5 were associated with a history of falling in the stroke population.
Awesome – congratulations on putting your new skills to work! It sounds like you nailed it. There are several options for treating most types of BPPV. For horizontal cupulolithiasis, the modified Semont/Casani is a common treatment. For horizontal canalithiasis, the BBQ roll and Apiani maneuvers are pretty equally effective.
Hi Alex,
I would expect peds questions on the NCS exam to pertain more to transitioning to adulthood. I wouldn’t worry too much about memorizing developmental milestones.I cannot find confirmation on the ABPTS website, but you should get a dry erase board or scrap paper on which to take notes.
This question states that the injury was a Seddon *and* Sunderland class 2 injury. Axonotmesis (Seddon class 2) has a wide range of possible recovery timelines, but Sunderland’s classification is more specific describing the injury as disruption of the axon with regeneration and full recovery expected.
Statistical power is dependent on randomization. Random assignment to groups will average out differences that could lead to type 1 and 2 errors.
Your test taking strategy on this one was correct – even if you don’t know why all the other answers are correct/incorrect, you know that an ANOVA is completed after the study so that must be the correct answer here.
