The athlete complains of instability when walking and reports an MOI of tibial external rotation and valgus.  In addition, they present with knee ROM of 10 of Extension and 75 degrees of Flexion. and you suspect an injury to the ACL. What special test would you perform to confirm your suspicion of an ACL injury?

You are performing an ankle MMT and apply your resistance force in the direction of eversion and slight dorsiflexion.  Which of the following muscles is being tested?

What does the Physical Performance Test (PPT) measure?

Your patient is positioned in sitting and you have asked him to lift his arm in the frontal plane, and you then apply resistance over the distal humerus. Which of the following muscles are you MMT’ing?

You may enter your answer to Question 1B in this textbox. Please see your printed exam booklet for the content related to this question. You must include your Exam Number at the top of your answer submission.

A PTA completes an MMT where resistance is applied toward PF and eversion. This description BEST describes an MMT of which of the following muscles?

The number of turns per meter in a solenoid of fixed length is doubled. At the same time the current in the solenoid is halved. The energy stored in the solenoid:

As shown in Fig. 2, a proton is projected with speed 3 . 90 × 10 6   m s into a region with a uniform electric field parallel to the velocity of the proton and then enters a region with a uniform magnetic field which is perpendicular to the proton velocity with a magnitude B → = 0 . 300   T . Both the width of the electric region and the width of the magnetic region are 20 . 0   c m . If the surface charge density of the left large plate in the electric field region is 6 . 00 × 10 – 6   C m 2 and the surface charge density of the right large plate in the electric field region is – 6 . 00 × 10 – 6   C m 2 , (a) what is the speed of the proton when it exits from the region of the electric field; (b) what is radius of path of the proton after it enters the region of magnetic field; (c) how much time does the proton stay in the region of the magnetic field; and (d) what are the x and y components of the velocity of the proton when it exits the magnetic region? If the magnitude of the magnetic field can be changed, (e) what is the magnitude of the magnetic field if the incoming proton exits the region of magnetic field in a direction opposite to its incoming direction? (mass of a proton= 1 . 67 × 10 – 27   k g ; charge of a proton= 1 . 60 × 10 – 19   C ) fig_q18_final.jpg                                                                 Fig. 2.1                                                                                                                                                                                                                                     Fig. 2.2

You are attempting to assess a patient’s cervical rotation strength. He is unable to perform the motion against gravity. The correct position to complete the test would be:

Mrs. P underwent (R) total hip surgery last week. You have been working on exercise, and gentle stretching activities with her and she is making excellent progress. The supervising PT has asked you to take goniometric measurements and MMT’s of her (R) leg. Prior to today’s session, you notice that the IV in the (R) dorsum of her hand has infiltrated. Is it safe for you to proceed with assessment as planned?
