Chapter 10, Problem 2CCS
45-Year-Old Female with Motor Nerve Damage
In Chapters 7 and 8, you met Kayla Tanner, who suffered a dislocated right hip in a car accident. Six weeks later, Mrs. Tanner was still unable to walk or run without hip pain, and had weakness in flexion at the knee, excessive foot inversion and plantar flexion, and significant “foot drop” (the inability to dorsiflex the foot).
Electromyography (measurement of muscle electrical activity) and nerve conduction studies (measurement of the speed of nerve impulses) revealed sciatic nerve damage, most likely a result of the nerve being compressed when the hip was dislocated. This large nerve innervates many lower limb muscles. Since her surgery, Mrs. Tanner has been undergoing intense physical therapy and has shown significant improvement.
2. To assess the function and strength of a specific muscle, a physical therapist will often apply resistance (push against the moving limb) to mimic the action of an antagonist muscle. What is an antagonist muscle, and why would the therapist mimic its action?

A 27-year-old man is brought to the emergency department because of gluteal pain and difficulty walking since sustaining an injury in a football game 3 days ago. He says that he trips on the toes of his left foot. He is a running back and was cutting through the line when he felt a pop in his gluteal region on the left side and had immediate pain. Physical examination shows deep gluteal tenderness. An MRI of the injured area today shows inflammation deep to the gluteus maximus in the area of the piriformis muscle. The physician suspects that there is compression of the common fibular (peroneal) branch of the sciatic nerve as it pierces the muscle. Which of the following additional findings is most likely on examination of this patient?
A) Loss of cutaneous sensation to the plantar foot
B) Loss of cutaneous sensation to the posterior thigh
C) Loss of eversion of the foot
D) Loss of inversion of the foot
E) Trendelenburg sign
F) Weakened extension at the hip
G) Weakened extension at…
is patellafemoral pain syndrome a arthogenic or myogenic condition and how can you distinguish it from other conditions
For this set of questions you will need to stand up from the chair you are sitting in,
and then sit back down. Do this slowly so that you can pay attention to what is
happening, and if necessary feel the tone of the muscles in your legs as your
standing and sitting (If you are lying down or standing start from a seated position,
then stand, then sit).
a) During the standing phase, what function is being carried out at the hip joint?
b) What are the prime movers (agonists) that are responsible for this particular
movement (Hint: You should be able to feel them activated)?
c) During the standing phase, what function is being carried out at the knee joint?
d) What are the prime movers (agonists) that are responsible for this particular
movement (Hint: You should be able to feel them activated)?
e) As you sit back down, you realize that some of the same muscles activated during
standing are also active when going from standing to sitting. Explain?

- bular ligamen A 68-year-old woman comes to the emergency department due to pain in the left uppe arm after a fall from standing height. Medical history is significant for hypothyroidism and hypertension. Physical examination shows bruising of the shoulder. Left arm movement is limited due to pain. Plain radiographs reveal a nondisplaced left hume fracture at the anatomical neck. This patient is at greatest risk for which of the following complications? A. Biceps tendon rupture B. Brachial artery tear C. Humeral head necrosis D. Median nerve injury E. Radial nerve palsyarrow_forwardA 20-year-old man complained that he was unable to raise his right upper limb. He held it limply at his side with his forearm and hand pronated. During questioning by the physician, he stated that he had been thrown from his motorcycle approximately 2 weeks previously and that he had hit his shoulder against a tree. He also recalled that his neck felt sore shortly after the accident. Physical Examination: On examination it was found that the patient was unable to flex, abduct, or laterally rotate his arm. In addition, he lost flexion of the elbow joint. A lack of sensation was detected on the lateral surface of his arm and forearm. The physician requested radiographs of the cervical and pectoral girdle regions. Radiology Report: No fractures are seen in the cervical region, pectoral girdle, and proximal part of the humerus. Diagnosis: Injury of nerves derived from the brachial plexus.

He has a history of right hemiplegia (right sided paralysis) one year back. Manual muscle testing of hip flexors was Grade 4, hip extensors Grade 5 and hip abductors Grade 3. While assessing his gait pattern his left pelvis dropped with every step. His X-ray of hip, knee and ankle showed normal alignments with mild signs of osteoarthritis. 1.
