Questions 17-19 are based upon the following case study about Robby.  CASE: Robby is a 19-year-old male who works at a steel manufacturing plant. At work Robby experienced a severe laceration from a machine across the distal portion of his right (dominant side) volar forearm. The laceration was about ¼ inch deep and nearly four inches wide. In the hospital, the surgeons were able to perform tendon and muscle repair. At this point it is unclear if any nerves were damaged due to the laceration. After spending 8 weeks in a partial cast (no movement allowed), Robby has his first outpatient therapy evaluation with you today. Now the doctor has ordered full range of motion and strengthening as tolerated. However, his movement is somewhat limited and stiff due to immobilization and repair. Because of his manual labor job and active lifestyle, he has muscular forearms and larger hands.    Which movement is likely to be weak and/or absent at this point in recovery?

NOTICE: This case will be used for the following 3 questions of your exam. Make sure to answer every fill in the blank Mrs. White is a 55 year-old woman is 6-months post right total knee arthroplasty (TKA). She was discharged from home health physical therapy services 5 months ago. Her normal bed time routine always begins with a hot bath. Mrs. White currently depends on her upper body strength to lower herself into the tub because her right lower extremity is still weak. In order to lower herself into the tub, she stands with both feet firmly planted in the tub. Mrs. White flexes her hips and places her hands on both sides of the tub. She uses her arms to lower herself down into the tub (Phase I). When she is done with her hot bath, she pushes up with both hands on the side of the tub to return to standing (Phase II).   During phase I of lowering into the tub:    A) What type of contraction, if any, is occurring in the elbow flexors? __________________ B) What type of contraction, if any, is occurring in the elbow extensors? _______________

Because of his manual labor job and active lifestyle, he has muscular forearms and larger hands.  Which muscle and/or associated tendon(s) is LEAST LIKELY to be affected by the laceration?

What nerve innervates muscles in the posterior compartment of the arm and forearm? 

Radial deviation is not a “pure” movement (in other words, there is no single muscle that can contract and cause radial deviation). Forces from what muscles must combine in order to create radial deviation?

The figure below shows atrophy in the ___________ muscle group and is the result of __________ nerve injury/compression.
