A former football player has fusion at C5-6 and C6-7 to treat spinal stenosis.  The procedure greatly improves pain symptoms but results in limits in the patient’s cervical AROM.  The patient is concerned about having adequate rotation ROM.  In discussing the patient’s expected limitations, the PT informs the patient that 50% of cervical rotation occurs at which joint?

A PTA is treating a patient with bilateral knee pain.  During the initial evaluation, the PT noted bilateral genu recurvatum.  Genu recurvatum may result from this pathological gait:

The esophageal stage of swallowing is

When a liquid or solid enter the airway below the level of the vocal folds, this is known as 

Let u→{“version”:”1.1″,”math”:”u→”}=−7i−9j and  v→{“version”:”1.1″,”math”:”v→”}=−3i+3j. Find u→+v→{“version”:”1.1″,”math”:”u→+v→”}

Suppose that u→{“version”:”1.1″,”math”:”u→”}=⟨8,−2⟩ and v→{“version”:”1.1″,”math”:”v→”}=⟨5,−5⟩. What is the angle betweenu→{“version”:”1.1″,”math”:”u→”} and v→{“version”:”1.1″,”math”:”v→”}, rounded to the nearest degree?

Let u⃗ =⟨7,−4⟩ and v⃗ =⟨3,4⟩. Find u⃗ −v⃗ .

Given the points H(−5,−1) and G(−2,3), determine the position vector of GH→{“version”:”1.1″,”math”:”GH→”}

The equation T=0.8sin(π28{“version”:”1.1″,”math”:”π28″}(t−7))+101.2 describes the body temperature of a pig in Fahrenheit, where t is time in hours. What is the temperature of the pig to the nearest tenth of a degree when t=2? Do not include units in your answer.

Find the unit vector in the same direction as v→{“version”:”1.1″,”math”:”v→”}=⟨−5,−6⟩.
